Recently heart attack age ramipril 10 mg order otc, the British Association of Pediatric Urologists published the following appropriate guidelines in a Consensus Statement: 1. Temporizing procedures such as cutaneous ureterostomy, cutaneous pyelostomy, or refluxing ureteral reimplantation should be performed for patients younger than 1 year of age. Ideally, the procedure should be deferred until 1 year of age and allow for a definitive ureteral reimplantation. Follow-up: the British Association of Pediatric Urologists recommends long-term follow-up into adulthood because of the risk for late asymptomatic deterioration (Farrugia et al. Significant compression of the thoracic region from bladder distention coupled with decreased amniotic fluid may lead to immediate need for pulmonary resuscitation. However, the only reliable method to determine the etiology is through direct visualization with fetal cystoscopy (Morris et al. As mentioned earlier in this chapter, with prenatal counseling, a narrow window between 18 and 24 weeks is the ideal time to consider intervention, which should be preceded by extensive counseling in regard to the expected benefits in relation to the relatively high complication rate (Elder et al. After delivery, the urologic team should be immediately on hand to aid in bladder decompression. Digital rectal pressure may be needed to direct the drainage catheter over the high riding bladder neck in some patients. The neonatal team should be advised to avoid using a balloon catheter as it may drop down into the posterior urethra and obstruct or damage the urethra and impair drainage of the ureteral orifices (Jordan and Hoover, 1985). If one cannot pass a catheter into the urethra, then a percutaneous suprapubic catheter can be placed with ultrasound confirmation at the bedside using local anesthesia and an angiocatheter using the Seldinger technique. Unfortunately, the ability to identify this condition prenatally does affect the natural history of this condition with about one-third developing the need for long-term renal replacement. Prune Belly Syndrome/Megalourethra the constellation of massive dilation of the bladder (megacystis) and upper urinary tract combined with the physical examination findings of absent/decreased rectus abdominal wall musculature with bilateral nonpalpable testes confers the diagnosis of prune belly syndrome (see Chapter 32 for a more detailed description). Urethral Stenosis/Atresia Urethral stenosis and/or atresia more commonly resides with the constellation of signs that include oligohydramnios, severe bilateral urinary tract dilation, and bladder distention. Postnatally, a catheter will not pass into the bladder, and a narrowed penile urethra with a membrane at the level of the membranous/prostatic urethra can be seen on cystoscopy. Prenatal ultrasound scan demonstrating "keyhole" sign indicative of lower urinary tract obstruction. Transverse ultrasound image of the bladder demonstrating marked thickening of the urinary bladder after decompression and associated bilateral distal ureteral dilation. Equally, the neonatal team should be advised of the likely concentrating defect inherent with these disease processes that may be exacerbated with a postobstructive diuresis. A repeat ultrasound scan should be obtained to serve as a baseline for maximal decompression following intervention.

Sonographically fetal arrhythmia 38 weeks 10 mg ramipril sale, it is important to characterize the renal cortex, medulla, and corticomedullary differentiation as well as the size, location, and number of cysts. Ultrasound is helpful not only in diagnosis of renal cysts but also for evaluation of hepatic involvement as well as for monitoring of complications such as hemorrhage and nephrolithiasis. Multicystic dysplastic kidney is the most common cause of cystic disease in children (Cardona-Grau and Kogan, 2015). It is characterized by multiple noncommunicating cysts of varying sizes with no identifiable normal renal parenchyma. Similarly, there is no indication for performing serial ultrasound examinations, although the examiner may perform one additional ultrasound at 1 year to adequately evaluate the contralateral solitary kidney with any further follow-up imaging guided by any abnormality of the contralateral kidney, abnormal blood pressure, or enlarging multicystic dysplastic kidney. Although not validated in children, a modified Bosniak classification may be used as a guideline to direct the need for surgical intervention because of an increased risk of malignancy (Wallis et al. This should be differentiated from a calyceal diverticulum, which is a cystic cavity within the kidney that communicates with a calyx or, less commonly, with the renal pelvis through a narrow isthmus (Ochoa Santiago et al. Although a calyceal diverticulum is often misdiagnosed Referral for Ultrasound Findings Prenatal Hydronephrosis. Dilation of the fetal renal collecting system, prenatal hydronephrosis, is one of the most common abnormalities detection on prenatal ultrasonography, occurring in up to 5% of all pregnancies. Several grading systems have been developed in attempt to correlate prenatal and postnatal ultrasound findings with the ultimate urologic diagnosis. There are several grading systems ranging from descriptive to semiquantitative to quantitative. Most recently, a multidisciplinary consensus panel developed the Urinary Tract Dilation Classification System based on anterior posterior renal pelvic diameter, calyceal dilation, parenchymal thickness, and appearance of the ureter and bladder (Nguyen et al. The diagnosis of prenatal hydronephrosis may cause significant parental anxiety and physician uncertainty with regard to prenatal and postnatal management. Variations in the definition and management of prenatal hydronephrosis make accurate counseling regarding the risk of postnatal pathology challenging (Lee et al. Based on postnatal imaging studies, up to two-thirds of antenatal hydronephrosis is due to transient hydronephrosis. Clear cell sarcoma commonly metastasizes to the bone, and some variants can be challenging to differentiate from Wilms tumors. Finally, renal medullary carcinoma is seen almost exclusively in patients with sickle cell disease/trait. Calyceal diverticuli are usually asymptomatic; treatment is indicated if associated with pain or infection, abscess formation, urosepsis, or symptomatic calculus formation (Estrada et al.

These two results are not necessarily in conflict blood pressure erectile dysfunction 5 mg ramipril buy mastercard, as they were performed under conditions with different pretest probabilities for urinary tract infection. We recommend to parents and patients with isolated malodorous urine in the absence of other signs or symptoms of urinary tract infection to increase hydration so as to alter the specific gravity of the urine and dilute volatile compounds. This avoids further testing in most cases and subsequent overtreatment, which fosters antibiotic-resistant organisms. Overtreatment can compound the difficulty in treating patients who develop true symptomatic, recurrent urinary tract infections. Additional Testing Blood samples are rarely indicated in the typical workup of lower urinary tract dysfunction, unless the history, physical examination, or other testing reveals possible underlying kidney disease or risk factors for the development of kidney disease. This important document codifies language to describe results of tests in common terms, thus allowing researchers and clinicians to compare studies and results on a comparable basis, avoiding ambiguous older verbiage. We highly recommend that all clinicians who treat patients with lower urinary tract dysfunction read this important paper. Noninvasive Testing Uroflowmetry Uroflow studies measure the flow of urine during urination. The most important variables obtained by the uroflow are voided volume, Qmax, and void pattern (Van De Beek et al. These are not absolute, but they do provide a guide to possible underlying etiologies of lower urinary tract dysfunction. A healthy child of any age, sex, race, or voided volume should result in a bell-shaped curve. A high-amplitude, peaked curve of short duration suggests an overactive bladder with sudden detrusor contraction. Not all children with overactive bladder, however, present with this voiding phenotype. This flow pattern is irregular and fluctuates but does not reach zero flow during voiding. Intermittent sphincter overactivity is suggested to be the underlying cause and is felt to be associated with bowel and bladder dysfunction. Like the staccato curve, the interrupted shape uroflow result is also irregular, but there are segments of the curve that read zero flow, indicating cessation of urination and inadequate detrusor contraction (as in underactive bladder with Valsalva voiding). This uroflow result is a flat, low-amplitude prolonged flow curve that is suggestive of downstream obstruction (bladder outlet, posterior urethral valves, urethral stricture). This curve type may also be seen in patients with underactive bladder, whereby a continuous, low-amplitude pressure either from the detrusor or Valsalva generates force to expel urine. Peaks may be artifactual, so Qmax should be only be registered when the peak lasts at least 2 seconds (Szabo and Fegyverneki, 1995). Multiple attempts have been made to find objective, quantifiable methods to normalize uroflow results to allow better comparisons between different patients (Chang and Yang, 2008; Kanematsu et al. Some of these efforts were suboptimal or based on populations that lacked generalizability. Total volume is usually recorded, and a minimum of ~50 to 100 mL is needed to qualitatively assess urine flow pattern.

On the other hand prehypertension american heart association ramipril 5 mg purchase on-line, construction of a new tunnel with a full 5:1 length-to-diameter ratio may not be absolutely required to correct reflux (Villanueva et al. Conditions caused by innate bladder detrusor pathology are usually considered to be of either a neurogenic or non-neurogenic origin as well, as in the case of spinal pathology or again, dysfunctional voiding, respectively. In particular, neurogenic bladder associated with spina bifida is at risk for reflux (Bauer et al. Special attention to the potential for occult spinal dysraphism, including sacral dimple, hairy patch, gluteal cleft abnormality, diminished rectal tone, or significant and often refractory constipation or encopresis, should prompt consideration for investigation of coexistent spinal cord abnormalities. Urodynamic extremes that predispose to reflux in the absence of abnormal neurologic conditions may also exist. Some studies suggest that a secondary aspect to neonatal reflux is a peculiarity found in male infants. Normal or immature voiding patterns were observed in all infants in the nonrefluxing control group, of which 16 of 21 were male. In infants, higher voiding pressures are associated with reflux, particularly in boys (Chandra et al. This would explain the higher gender inequalities within this age range and also the high resolution rates and gender shift, which were previously discussed. Urodynamic evaluation suggests these elevated infant bladder pressures may be caused by inadequate sphincter relaxation during this stage of development (Chandra et al. However, detrusor activity in such infants is largely normal during filling, with slightly diminished bladder capacities in some (Podesta et al. Considering that the high prevalence for reflux in infants coexists with urodynamic evidence of elevated voiding pressures, these observations suggest that infant voiding patterns may be a part of normal development. The precise cause of bladder dysfunction is unclear, but may evolve from a persistence of the expected early attempts to suppress bladder contractions during the toilet-training months by volitional contraction of the external sphincter (Allen, 1985). Detrusor overactivity is the most common urodynamic abnormality associated with reflux in neurologically normal children and was found to be as high as 90% in one study of children with voiding dysfunction or idiopathic detrusor overactivity (Glassberg et al. In one study of 37 girls with primary reflux, 75% had overactive detrusor contractions (Taylor et al. However, the observation that treatment of such patients with oxybutynin can eliminate reflux in up to 80% of involved ureters strongly argues that an overactive bladder frequently can be partly responsible for reflux by either causing secondary reflux or perpetuating primary reflux (Seruca, 1989; Koff et al. A negative correlation was found between dysfunction at follow-up and reflux improvement (P =. In addition, scintigraphic renal abnormalities at study entry and at follow-up were also associated with dysfunction (P =. Failure to address bladder abnormalities can adversely affect the outcome of antireflux surgery (Koff et al. Neurogenic Caused by bladder Non-neurogenic Increased intravesical pressure Mechanical.

Although the advent of endourology and minimally invasive surgery has played an unprecedented role in minimizing morbidity blood pressure medication lipitor generic 10 mg ramipril mastercard, it has also introduced newly described and reported periprocedural complicating events. Training in urology has also witnessed another paradigm shift, from the era of classic surgical mentoring to the current use of simulators and virtual reality surgery. Learning curves of complex surgical procedures such as open radical prostatectomy once estimated to be around 100 to 1000 cases have dropped to 40 cases with robotic-assisted surgery. Surprisingly, complication rates have not followed the same trend, and some authors associate this with the increased number of young surgeons progressing through their learning curves. There has been a dramatic increase in the use of minimally invasive procedures in the surgical management of urologic disease. These include the wide range of modern endoscopic and endourologic procedures and the use of laparoscopic and robotic surgical techniques. As such, surgical training has also evolved with a dramatic decrease in the exposure to major open surgery in the average urologic training program. Today, major index and common urologic oncologic and reconstructive procedures are performed in a minimally invasive fashion. Although the new generation of surgeons are better trained in minimally invasive techniques, the principles for the treatment of major complications remains the same. Increased incidence of complications was associated with several factors, such as procedure complexity (laparoscopic partial nephrectomy and cystectomy), length of surgery greater than 4 hours, and serum creatinine greater than 1. Several studies have shown that complications increase up to ninefold with procedure complexity and decrease fourfold with surgeon experience. However, there is a unique set of complications related to pneumoperitoneum and access, for example. A high index of suspicion is necessary intraoperatively and postoperatively to detect and treat these complications in an expeditious and safe manner. Although technology has changed the actual performance of operations, it has also led to the development of minimally invasive means to treat surgical complications. These include interventional radiologic techniques and, in many instances, minimally invasive laparoscopic and/or robotic approaches to treat complications.

This model is further supported by the fact that oligohydramnios resulting from experimentally induced urinary obstruction is associated with pulmonary hypoplasia in fetal sheep that initially showed normal renal function (Peters et al arteria costa rica purchase ramipril paypal. Therefore, uropathy-associated pulmonary hypoplasia appears to be a predominantly the result of oligohydramnios during the canalicular phase of lung development rather than renal dysfunction (Peters et al. This observation is further supported by the fact that in some cases of anhydramnios or severe oligohydramnios, serial transabdominal amnioinfusion with saline has improved the fetal lung volume and also postnatal neonatal lung function (Vergani et al. Additional diagnostic findings include small lung volumes and chest diameter and abnormal adrenal gland appearance (Heling et al. The characteristic Potter facies and the presence of oligohydramnios are pathognomonic. A renal sonogram is recommended when these ear anomalies are found in the presence of other malformations. Renal aplasia is found in 1 in about 1300 births, which is similar to the incidence of renal agenesis and may be the most common cause of congenital solitary kidney. It is thought to be a result of early regression of the ureteric bud, altered metanephric differentiation, or defects in the reciprocal induction of the branching ureteric duct and the metanephric blastema. A flattened adrenal gland or the spleen (on the left) may be mistaken for a kidney on the 20-week structural ultrasound (Woolf and Hillman, 2007). Complete absence of a ureteric bud or aborted ureteral development prevents reciprocal induction of the metanephric blastema, which is critical for development into the definitive adult kidney. The metanephros is not likely to be responsible for the majority of cases, because the ipsilateral gonad (derived from adjacent mesenchymal tissue) is rarely absent, malpositioned, or nonfunctioning (Ashley and Mostofi, 1960). Absence of a kidney occurs somewhat more frequently on the left side, and a familial tendency for renal agenesis has been noted (Cascio et al. Others who evaluated families with more than one affected individual have confirmed this inheritance pattern (Roodhooft et al. Genetic/Syndromic and Other Associations An absent kidney has been noted in a number of genetic disorders in which there is a deletion of several chromosomal loci: 8q13. Maternal diabetes is associated with a threefold increased risk for renal agenesis and dysplasia (Davis et al. Animal studies have shown that the developing kidney is adversely affected by a high glucose environment, causing dysmorphogenesis of the metanephros and ureteric bud and disruptions in the normal process of nephrogenesis resulting in a reduced population of nephrons (Kanwar et al. Children with supernumerary nipples (Urbani and Betti, 1996) and disorders of the ears with hearing loss, especially if it is congenital (Huang et al. In most cases of complete absence of the ureters, the bladder showed no evidence of a ureteric orifice with failure of the ipsilateral trigone to develop (Ashley and Mostofi, 1960). Cell lineage studies using a murine model show that the trigone has a urogenital sinus origin and should form normally (Viana et al. Therefore, the endoscopic appearance of the trigone in this setting has led to the probable misnomer in the case of the "hemitrigone" (in association with complete ureteral agenesis) or "asymmetrical trigone" (in the presence of a partially developed ureter).

Findings in females with true renal agenesis also include an absent ipsilateral bladder hemitrigone blood pressure apple watch ramipril 2.5 mg sale. Usually the distinction between true agenesis versus dysplasia and atrophy does not have clinical implications. Because of section orientation, (A) depicts the lower portion of the specimen (the introitus to the upper vagina), and (B) depicts the upper portion of the specimen (vagina, cervix, and uterus) (H&E stain). The vaginal epithelium is many layers thick as a result of estrogenic stimulation (A and B). In (B), note the abrupt transition in epithelial differentiation at the vaginal/cervical border (*). Bladder: Ureteral Development Both the bladder and ureters consist of a urothelial-lined lumen, a lamina propria consisting of extracellular matrix with unorganized smooth muscle, an outer layer of thick bundles of smooth muscle, and a serosal surface. The ureters and bladders of human males and females develop in similar fashion without differences in size. Clinical Correlation: Vaginal Agenesis and Imperforate Hymen Failure of canalization of the vaginal canal results in atresia or blockage of the vagina. This occurs in approximately 1: 80,000 women and is called a transverse vaginal septum. The septum is typically located at the junction of the middle and superior third of the vagina. Obstructed hemivagina ipsilateral pelvic renal nubbin Healthy kidney and ureter Atrophic dysplastic kidney Septated uteri the Wolffian (mesonephric) ducts fuse with the cloaca just before its subdivision by the urorectal septum (Moore et al. The formation of these final connections involves apoptosis, which enables the ureters to disconnect from the mesonephric ducts and fuse to the bladder (Batourina et al. With use of cell-lineage studies (in mice), the fibromuscular wall of the trigone was found to form mostly from bladder smooth muscle cells with only a minor contribution from mesenchymal cells associated with the ureters (Viana et al. This is in contrast with the classic hypothesis in which the trigone is formed from an extension of the ureteral development into the trigone of the bladder (Weiss, 1988). The ureteral orifices incorporate into the bladder and migrate in a cranial and lateral direction within the base of the bladder. The embryonic pattern of ureteral orifice incorporation into the developing bladder is inferred primarily from clinical observations of duplex kidneys with two ureters joining the bladder on the same side. The upper-pole ureteral orifice rotates dorsally relative to the lower-pole orifice and assumes a more caudal and medial position. Weigert and Meyer recognized the regularity of this relationship between upper- and lower-pole ureteral orifices, which has come to be known as the Weigert-Meyer rule (Weigert, 1877; Meyer, 1907). According to this concept, an abnormally laterally placed lower-pole ureteral orifice may result from a ureteric bud arising too low on the mesonephric duct, therefore resulting in premature incorporation and migration within the developing bladder. In such an abnormal ureteral orifice, vesicoureteral reflux is more likely to occur because of an inadequate intramural tunnel.

Although this did not show an increased risk for urine leaks blood pressure chart preeclampsia generic 2.5 mg ramipril visa, early catheter removal remains an uncommon practice, with most surgeons recommending a 7- to 10-day catheterization requirement (Gratzke et al. Classification of urine leak severity will have to follow the ClavienDindo grading system in an effort to standardize reporting. It is evident though that attempts for grading urine leaks depended mainly on the need for intervention for proper management. Clinically significant urinary leaks consist of collections extraperitoneally in open radical prostatectomy or intraperitoneally after robotic prostatectomy. These can result in ileus, requiring extended hospital stay and intravenous fluids. When associated with fever and signs of sepsis, antibiotic therapy or percutaneous drainage is warranted (Mochtar et al. The incidence of re-intervention for vesicourethral anastomotic leakage ranges from 0. With increasing experience with robotic prostatectomy and the utilization of a watertight running anastomotic technique, the incidence of urinary extravasation has decreased. Then long-term sequelae can be a bladder neck contracture and a resultant fibrotic bladder neck. This can potentially contribute to a decrease in continence if the scar involves the external sphincter mechanism by decreasing sphincteric coaptation and function. However, bladder injuries are more common during gynecologic and at times colorectal procedures. The bladder is at risk for injury during a hysterectomy during the creation of a bladder flap when the bladder dome is dissected from the lower uterine segment. Intraoperative recognition is key, and repair can be performed in two layers with absorbable sutures. A urethral catheter should be left for 7 to 10 days to ensure adequate healing and decrease the risk for subsequent vesicovaginal fistulas. Postoperative presentation can mimic ureteral injuries with abdominal distension, ileus, fever, chills, leukocytosis, and increased drainage from pelvic drains. Intraperitoneal leaks are managed with robotic or open repair in two layers with absorbable sutures. On occasion, when a small, contained extraperitoneal leak is evident, management can be conservative Contributing Factors Postoperative blood loss is a predictor for the development of urinary extravasation. A postoperative hematocrit drop of more than 6 points identifies a group of patients at increased risk for urine extravasation. Other contributing factors are obesity, length of the operation, size of the bladder neck, and utilization or lack thereof of bladder neck reconstructive techniques (Fenig et al. Most urinary leaks are small, can be managed conservatively, and will spontaneously resolve with prolonged urethral catheter drainage.

Some conditions preclude primary closure heart attack flac torrent ramipril 5 mg buy low price, including penoscrotal duplication, ectopic bowel within the extruded bladder (a relative contraindication), a hypoplastic bladder, and significant bilateral hydronephrosis. Those delayed for small bladder templates tended to be older at the age of primary closure (305 days vs. Although the measured bladder capacities were smaller in the patients with a delayed primary closure, notably, the annual growth is similar (Baradaran et al. Thus waiting for the bladder template to grow for 6 to 12 months in the child with a small bladder is not as risky as submitting a small bladder template to closure in an inappropriate setting, resulting in dehiscence and possible future incontinence. Ultimately, delaying the primary closure when indicated does not jeopardize the growth of the bladder (Baradaran et al. If the bladder does not grow to sufficient size for closure after 6 to 12 months, other options include excision of the bladder and a nonrefluxing colon conduit or ureterosigmoidostomy. Osteotomy Children born with bladder exstrophy have not only an exposed bladder but also a wide diastasis of the pubic rami (average 4. In addition, if the pelvis is not malleable or if the pubic bones are more than 4 cm apart at the time of initial examination under anesthesia, osteotomy should be performed, even if closure is done before 72 hours of age. A well-coordinated surgery and anesthesia team can perform osteotomy and proceed to bladder closure without undue loss of blood or risk of prolonged anesthesia in the child. However, osteotomy together with posterior urethral and bladder closure and abdominal wall closure is a 5- to 7-hour procedure in these infants. If the patient is younger than 72 hours old and examination under anesthesia reveals that the pubic bones are malleable and able to be brought together easily in the midline by medial rotation of the greater trochanters, the patient can undergo closure without osteotomy. No chances should be taken with a decision of this magnitude, and if any doubt exists, an osteotomy should be performed. The most frequently used osteotomy today is the bilateral anterior innominate and vertical iliac osteotomy, popularized by Gearhart et al. This approach improves the ease of symphyseal approximation in the patient with exstrophy compared with posterior approaches. In our experience, this osteotomy is superior to the pubic mobilization seen with simple bilateral transverse anterior innominate osteotomy or even pubic ramotomy. With the ease of approximation obtained with this combined osteotomy, tension on the midline abdominal closure is lessened and the rates of bladder dehiscence and bladder prolapse are markedly decreased (Gearhart and Jeffs, 1998). In addition, pelvic closure allows anterior movement of the levator ani to strengthen the puborectalis sling. This helps position the bladder neck and posterior urethra deep within the pelvic ring and improved continence rates. This also moves the pelvic floor muscles into a more anterior position, thus providing more support for the anterior pelvic organs.

Presence of a lipoma arrhythmia pronunciation discount ramipril 5 mg, mass, or hair tuft overlying the spine or sacrum should also be investigated as these confer high risk for occult spinal dysraphism or tethered cord (Guggisberg et al. Ultrasonography of the spine may be appropriate for patients up to 6 months of age (ossification of the spine occurs by 10 to 12 months of age) for low-risk lesions, understanding that ultrasonography has been reported to have decreased sensitivity (50% to 70%) (Scheible et al. Abdominal Examination Abdominal exam should begin with visual inspection to note the presence of asymmetry or distention, which may indicate bowel gas, fecal retention, or underlying bowel dysfunction. Palpation of all four quadrants should be performed to uncover the presence of enlarged kidneys or bladder, abdominal masses, or palpable stool in the colon. Stool is typically only felt in patients with extreme cases of constipation and may be more appreciable in small children. Tenderness to palpation and/or fullness of the suprapubic area may indicate urinary retention or a full bladder. Household ambulators Nonfunctional ambulators Nonambulators Genital Examination Genitourinary examination should include inspection of the genitalia, looking for evidence of damp underwear or external genital irritation, which can occur with incontinence. Skin changes over the spine that are suspicious for spina bifida, including isolated macules, deviated cleft, protuberance or mass, or isolated tuft of hair. Chapter 28 Clinical and Urodynamic Evaluation of Lower Urinary Tract Dysfunction in Children 479 In the male patient, the penis should be inspected and examined. Any erythema, swelling, or tenderness of the prepuce should be documented as possible evidence of balanitis. Meatal stenosis only occurs in circumcised males, secondary to irritation of the exposed meatus that induces epithelialization to create a ventral web. Meatal stenosis is felt to only be relevant if there is significant deviation or narrowing of the stream, and patients and caregivers should be counseled that concurrent symptoms may not necessarily be attributable to this finding or improve with surgical correction. Inspection of the meatus may be sufficient along with clinical history, but our preference has been to observe the urinary stream directly during voiding to note stream caliber and direction. In the female patient, the introitus should be examined for pooling of urine or ongoing signs of inflammation (erythema, swelling). Labial fusion is common, particularly in children younger than 2 years of age who are still in diapers (Farage and Maibach, 2005). It will usually resolve spontaneously with time by the time of puberty as increased circulating estrogens change the vaginal epithelium (Williams et al. In some cases, labial fusion can result in pooling of the urine, which may result in urinary stasis and bacterial colonization, thus increasing the probability of developing a urinary tract infection (Leung and Robson, 1993). In cases in which there is ongoing concern, topical estrogen can be used, but families should be counseled that about 10% of cases will recur. If there is concern for continuous incontinence, the vaginal introitus should be examined for an ectopic ureteral orifice.

Aschnu, 54 years: Although the cause of urethral prolapse is likely multifactorial, episodic increases in intra-abdominal pressure are likely contributory (Lowe et al.
