We identified the incidence of acquired cryptorchidism among patients with proximal and mid shaft hypospadias, predictors of acquired cryptorchidism, and the prevalence of testis-epididymis nonfusion with ascended testes. We hypothesized that proximal hypospadias would be associated with higher incidence of acquired cryptorchidism than mid shaft hypospadias, and that ascended testes would exhibit increased prevalence of testis-epididymis nonfusion similar to anatomical findings in an undescended testis.A retrospective cohort study of patients who underwent primary proximal and mid shaft hypospadias repair from 2010 to 2016 was conducted. Clinical and operative notes were reviewed. Patients with congenitally undescended testes or differences of sex development were excluded.A total of 175 patients were identified. Those with proximal hypospadias (14/104, 13%) were more likely than those with mid shaft hypospadias (1/71, 1%) to develop acquired cryptorchidism (p=0.04). Among proximal hypospadias patients, increased risk of acquired cryptorchidism was associated with pre-term birth (p0.01) and penoscrotal transposition (p=0.01) but not with testis position on initial examination (p0.99). In the 14 proximal hypospadias patients with acquired cryptorchidism, 21 ascended testes underwent orchiopexy. Operative notes adequately described testis-epididymis anatomy for 8/21 ascended testes. Testis-epididymis nonfusion was described in 6/8 ascended testes.Risk of acquired cryptorchidism is increased among patients with proximal hypospadias. Operative notes revealed a high rate of epididymal nonfusion with ascended testes, suggesting these testes morphologically resemble undescended testes. Close followup of testis position is needed in these patients, and the threshold to perform orchiopexy may need to be lower in select patients.

Among some populations access to neonatal circumcision has become increasingly limited despite evidence of its benefits. This study examines national neonatal circumcision trends before and after the 2012 American Academy of Pediatrics recommendation for neonatal circumcision reimbursement.A retrospective cohort study of boys aged 28 days or less was conducted using data from the Kids' Inpatient Database (2003 to 2016). Boys who underwent neonatal circumcision prior to discharge were compared to boys who did not. Boys with coagulopathies, penile anomalies or a history of prematurity were excluded.An estimated 8,038,289 boys comprised the final cohort. Boys were primarily White (53.7%), privately insured (49.1%) and cared for at large (60.8%) teaching (49.4%) hospitals in metropolitan areas (84.1%). While 55.0% underwent circumcision prior to discharge, neonatal circumcision rates decreased significantly over time (p0.0001). Black (68.0%) or White (66.0%) boys, boys in the highest income quartile (60.7%) and Midwestern boys (75.0%) were most likely to be circumcised. Neonatal circumcision was significantly more common among privately (64.9%) than publicly (44.6%) insured boys after controlling for demographics, region, hospital characteristics and year (p0.0001). The odds of circumcision over time were not significantly different in the years before vs after 2012 (p=0.28).Among approximately 8 million boys sampled over a 13-year period 55.0% underwent neonatal circumcision. The rate of neonatal circumcision varied widely by region, race and socioeconomic status. The finding that boys with public insurance have lower circumcision rates in all years may be related to lack of circumcision access for boys with public insurance.

We assessed the probability of bladder augmentation/diversion and clean intermittent catheterization in classic bladder exstrophy in a multi-institutional cohort.We included children born from 1980 to 2016 with bladder exstrophy and treated across 5 centers (exclusion criteria less than 1 year followup after birth, isolated epispadias, bladder exstrophy variants etc). Outcomes were probability of bladder augmentation/diversion after bladder closure and proportion of patients performing clean intermittent catheterization at last followup. Survival analysis was used.Of 216 patients 63.4% were male (median followup 14.4 years). Overall 4 patients (1.9%) underwent primary diversion and 212 underwent primary closure (72.6% in first week of life). After primary closure 50.9% underwent augmentation, 4.7% diversion and 44.8% neither. By age 18 years 88.5% underwent a bladder neck procedure (synchronous augmentation 27.3%). On survival analysis the probability of bladder augmentation/diversion was 14.9% by age 5 years, 50.7% by 10 years and 70.1% by 18 years. Probability of bladder augmentation/diversion varied significantly between centers (p=0.01). Probability of bladder augmentation/diversion was 60.7% 10 years after bladder neck procedure. At last followup of the entire cohort 67.4% performed clean intermittent catheterization. Among 95 patients with intact native bladders 30.5% performed clean intermittent catheterization (channel 72.4%). Among 76 adults without a diversion 85.5% performed clean intermittent catheterization (augmented bladder 100.0% clean intermittent catheterization, native bladder 31.3%). Fifteen patients underwent diversion (continent 8, ureterosigmoidostomy 5, incontinent 2).On long-term followup probability of bladder augmentation/diversion increased with age, with 1 in 2 patients by age 10 years and the majority in adulthood. Probability of bladder augmentation/diversion differed among institutions. Almost a third of patients, including adults, with a closed native bladder performed clean intermittent catheterization. Considering all adults only 14% did not perform clean intermittent catheterization.

Ureteral complications following renal transplantation are more common in children than in adults. We identify potential risk factors for ureteral complications in pediatric patients.We retrospectively studied a cohort of patients who underwent renal transplantation at Lurie Children's Hospital between 2004 and 2016. We analyzed the associations between patient characteristics, operative factors, graft characteristics and postoperative complications.A total of 224 renal transplantations in 219 patients were identified. Preexisting bladder pathology was present in 25% of cases. Overall rate of ureteral complications was 16%, with symptomatic vesicoureteral reflux being the most common. Ureteral complications were seen significantly more frequently in patients with underlying bladder pathology (26% vs 12%, p = 0.01). Rate of postoperative vesicoureteral reflux in patients with bladder pathology was lower when a urologist performed the reimplantation but the difference was not statistically significant (15% vs 27%, p = 0.35). Urologists were significantly more likely to perform the ureteral anastomosis in patients on clean intermittent catheterization (85% vs 43%, p = 0.004) and in patients with a history of complex bladder reconstruction (75% vs 28%, p0.001).Patients with existing bladder pathology are at increased risk for ureteral complications, particularly vesicoureteral reflux. Since pediatric urologists routinely perform ureteral reimplantation in patients with existing bladder pathology, these patients may benefit from a multidisciplinary approach between urology and transplant surgery at renal transplantation.

We describe our experience with 2-stage proximal hypospadias repair. We report outcomes, and patient and procedure characteristics associated with surgical complications.We retrospectively studied patients with proximal hypospadias who underwent staged repair between January 1993 and December 2012. Demographics, preoperative management and operative technique were reviewed. Complications included glans dehiscence, fistula, meatal stenosis, nonmeatal stricture, urethrocele/diverticula and residual chordee. Cox proportional hazards model was used to evaluate the associations between time to surgery for complications and patient and procedure level factors.A total of 134 patients were included. Median patient age was 8.8 months at first stage surgery and 17.1 months at second stage surgery, and median time between surgeries was 8 months. Median followup was 3.8 years. Complications were seen in 71 patients (53%), with the most common being fistula (39 patients, 29.1%). Reoperation was performed in 66 patients (49%). Median time from urethroplasty to surgery for complication was 14.9 months. Use of preoperative testosterone decreased risk of undergoing surgery for complication by 27% (HR 0.73, 95% CI 0.55-0.98, p = 0.04). In addition, patients identified as Hispanic were at increased risk for undergoing surgery for complications (HR 2.40, 95% CI 1.28-4.53, p = 0.01).We review the largest cohort of patients undergoing 2-stage hypospadias repair at a single institution. Complications and reoperation rates were approximately 50% in the setting of complex genital reconstruction.

Research on health related quality of life in patients with bladder exstrophy has demonstrated mixed results compared to population samples. Few studies have had a comparison group with a urological disorder and none correlated body image to health related quality of life. We compared health related quality of life in patients with bladder exstrophy to that in patients with kidney stones and correlated body image to health related quality of life in the bladder exstrophy population.Participants included 24 patients with kidney stones and 24 with bladder exstrophy. Patient age was 8 to 25 years. Participants completed the PedsQL (Pediatric Quality of Life Inventory) and the 25-item multiple choice UBIQ (Urological Body Image Questionnaire), which was created for the current study.Compared to patients with kidney stones those with bladder exstrophy indicated significantly higher scores on physical functioning (p = 0.0005) and overall health related quality of life (p = 0.02) in the 8 to 17-year-old cohort. When health related quality of life was compared to body image in patients with bladder exstrophy, lower social scores were associated with those who worried about friends finding out about the condition (p = 0.01) and about having romantic relationships (p = 0.003). Lower social (p = 0.006) and emotional (p = 0.009) functioning scores were associated with patients who thought that they were less likely to have romantic relationships.The finding that patients with bladder exstrophy had a better physical functioning score than those with kidney stones is not surprising, given the morbidity of active stone disease. The negative correlations with body image in the bladder exstrophy population may be due to the possibility of others discovering the condition and the perceived likelihood of not having romantic relationships.

Although research in patients with urological conditions indicates that functional limitations, pain, limited mobility and social restrictions can impact self-image, to our knowledge the influence of the visibility of the condition has not been examined. We assessed body image and self-image at school age through young adulthood in patients with bladder exstrophy compared to patients with kidney stones.Patients diagnosed with bladder exstrophy and kidney stones completed a 25-item multiple choice Urological Body Image Questionnaire for ages 13 to 25 years, which was created for the current study. It consists of questions on physical appearance, avoidance behaviors, urological condition disclosure, romantic relationships and future expectations. A modified Urological Body Image Questionnaire for patients 8 to 12 years old was created by removing questions on relationships and future expectations.A total of 24 patients with bladder exstrophy and 24 with kidney stones 8 to 25 years old completed the questionnaire. Compared to patients with kidney stones, patients with bladder exstrophy were significantly more likely to avoid changing clothes in front of peers and to not tell friends about the condition (each p = 0.0001). Patients with bladder exstrophy were also significantly more likely to think that the condition would prevent having future romantic relationships (p = 0.002) and children (p = 0.003).Differences in the visibility and privacy of the 2 conditions likely explain the discrepancy between the groups. Findings may call for an individual approach to assessing issues related to self-esteem and identity in patients with bladder exstrophy and may highlight the importance of receiving psychosocial support.

The impact of diagnostic genitourinary imaging on patients and families is poorly understood. We measured patient and family reaction to commonly performed genitourinary imaging studies using a standardized measurement tool.We surveyed families undergoing genitourinary imaging (renal ultrasound, voiding cystourethrography, radionuclide cystogram, static renal scintigraphy and diuretic renal scintigraphy) using a Likert scaled 11-item survey to assess impact across 4 domains (pain, anxiety, time, satisfaction). Survey scores were analyzed using ANOVA and linear regression.A total of 263 families were surveyed (61 renal ultrasound, 52 voiding cystourethrogram, 55 radionuclide cystogram, 47 mercaptoacetyltriglycine dynamic renal scintigraphy, 48 dimercaptosuccinic acid static renal scintigraphy). Mean patient age was 2.1 years old. Of the patients 45% were male and 77% were white. Patient age, gender and prior genitourinary imaging experience varied by study type. Study type was significantly associated with total and weighted scores on the genitourinary imaging survey (both p0.0001). Renal ultrasound was scored as better and mercaptoacetyltriglycine dynamic renal scintigraphy was worse than voiding cystourethrogram, radionuclide cystogram and dimercaptosuccinic acid static renal scintigraphy, which did not differ from each other. Other factors associated with worse total scores included patient age 1 to 3 years (p0.001) and nonwhite race (p = 0.04). Gender, prior testing history, wait time and parent education were not associated with total scores. In the multivariate model renal ultrasound remained the best and mercaptoacetyltriglycine dynamic renal scintigraphy the worst (p0.0001). In a direct comparison dimercaptosuccinic acid static renal scintigraphy and voiding cystourethrogram total scores did not differ (p = 0.59).There were significant differences among genitourinary imaging studies regarding the patient/family experience, but there was no overall difference between dimercaptosuccinic acid static renal scintigraphy and voiding cystourethrogram. These findings may be useful to aid decision making when considering genitourinary imaging for children.

We have previously shown that nonwhite patients with ureteropelvic junction obstruction undergo pyeloplasty at a younger age than white patients. The mechanisms behind this finding are unclear, since there is no known racial variation in the natural history of ureteropelvic junction obstruction. We used a detailed clinical database to explain this phenomenon.We retrospectively reviewed all patients undergoing primary pyeloplasty at our institution between 1992 and 2008. More than 360 data points were abstracted for each patient, including self-reported race, socioeconomic status, symptom duration and presentation.Of 847 patients undergoing pyeloplasty during the study period 741 met inclusion criteria. Nonwhite patients underwent surgery at a younger age (0.6 years) than whites (2.6 years, p0.0001). When stratified by timing of clinical presentation (prenatal vs postnatal), there was no significant difference in race among patients presenting prenatally (0.37 vs 0.36 years, p = 0.22). Nonwhite patients presenting postnatally were significantly younger than white patients (6.3 vs 8.2 years, p = 0.03). This finding appeared to be due to differences in age at initial clinical presentation (5.4 vs 7.0 years, p = 0.03) and in time from initial clinical presentation to urological evaluation (0.6 vs 3.2 months, p = 0.03). These differences persisted after correcting for other factors, including markers of socioeconomic status.Consistent with previous studies, we found that nonwhite patients underwent primary pyeloplasty at a younger age than whites. This difference is limited to patients presenting after birth. Prenatally diagnosed patients underwent surgery at similar ages regardless of race.

A major goal of bladder exstrophy management is urinary continence, often using bladder neck reconstruction. We report our experience with bladder neck reconstruction after complete primary repair of exstrophy.Patient history, ultrasound, voiding cystourethrogram, examination using anesthesia and urodynamics were performed during a prospective evaluation. Continence was assessed using the International Children's Continence Society classification and the dry interval. Bladder capacity was measured by examination using anesthesia, voiding cystourethrogram and/or urodynamics. Urodynamics were also done to assess bladder compliance and detrusor muscle function.From 1994 to 2010 we treated 31 male and 15 female patients with bladder exstrophy after complete primary repair of exstrophy. Of patients 5 years old or older bladder neck reconstruction was performed after complete primary repair in 9 of 21 males (43%) and in 3 of 11 females (27%) at a mean age of 6.3 and 8.1 years, respectively. By the International Children's Continence Society classification 6 of 12 patients (50%) were continent less than 1.5 years after bladder neck reconstruction and 2 of 9 (23%) were evaluable 1.5 years or greater after reconstruction. Median bladder capacity was 100 ml before, 50 ml less than 1.5 years after and 123 ml 1.5 years or greater after bladder neck reconstruction. Three males and 2 females emptied via an appendicovesicostomy. Two boys underwent augmentation.In our experience most patients with bladder exstrophy require bladder neck reconstruction after complete primary repair of exstrophy. The need for reconstruction is more common in males. Our rates of bladder neck reconstruction after complete primary repair of exstrophy and of continence after bladder neck reconstruction are similar to those in other reports.

Optimal management for bulbous urethral stricture in children is poorly defined. We compared our long-term experience with direct vision internal urethrotomy and open repair to define the optimal surgical strategy.We reviewed the records of 63 patients who underwent direct vision internal urethrotomy or open repair. A total of 46 patients (73%) were treated with 1 or more urethrotomies. Of the patients 17 (27%) underwent urethroplasty, 13 underwent end-to-end repair and 4 received a patch graft or tube. Eight of 17 cases required urethroplasty only, whereas in 9 combined open repair and urethrotomy were done. Mean patient age was 14.1 years (range 5 months to 21 years). Followup included voiding cystourethrogram, retrograde urethrogram and/or cystoscopy, or flow rate. Mean followup was 30 months for urethrotomy and 16 months for open urethroplasty.When direct vision internal urethrotomy was the initial approach, 1 procedure was successful in 28 of 53 cases (53%). Multiple urethrotomies increased the success rate to 59% (43 of 73 cases). The 53 patients with urethrotomy required a total of 84 procedures (mean 1.6 each). When open repair was the initial approach, 1 procedure was successful in 8 of 10 cases (80%). A total of 12 procedures (mean 1.2 each) were required in those 10 cases. A combined urethrotomy/open approach with 2 procedures was successful in 78% of cases (7 of 9).Open reconstruction is more successful than direct vision internal urethrotomy as the initial approach to bulbous urethral strictures. Although aggressive, end-to-end repair usually provides a definitive solution. Initial direct vision internal urethrotomy is successful in half of the cases and repeat urethrotomy adds little to success. The success of the combined urethrotomy/open approach approximates that of initial open reconstruction. If initial direct vision internal urethrotomy is elected, we advocate only 1 attempt, followed by open end-to-end urethroplasty if necessary.

Endoscopic treatment of vesicoureteral reflux has gained popularity and is frequently used as a first-line therapy. Reports of potential long-term complications from this treatment modality are lacking. We review the development of mound calcification in a cohort of patients undergoing endoscopic treatment of vesicoureteral reflux with autologous chondrocytes.All patients who underwent endoscopic treatment of vesicoureteral reflux with autologous chondrocytes at our institution were included in this study. All available renal and bladder ultrasounds, as well as any other imaging studies of the urinary tract, were reviewed by a staff radiologist (HJP) and 2 urologists (PCG, DAD) to assess for the presence of mound calcification. A variety of clinical factors were assessed, including grade and laterality of initial reflux, volume of autologous chondrocytes injected, number of injections, postoperative mound appearance and mode of presentation. Statistical comparison between groups was performed by paired sample t test and Fisher's exact test. Univariate and multivariate analysis was used to identify potential risk factors for the development of mound calcification.Total median followup was 9 years (range 7 to 11). Mound calcifications developed in 10 of our 27 patients (37%) at a median interval of 2.1 years after injection (range 1 to 5). More females (40%) than males (28%) had calcifications, although the difference was not statistically significant. Of the 10 patients with mound calcifications 7 presented with gross or microscopic hematuria, with or without flank pain. Three of these patients were initially thought to have ureterovesical junction stone(s). The remaining 3 cases were found incidentally. Hydroureteronephrosis was absent in all patients with mound calcifications. Univariate and multivariate analyses revealed no relationship between the presence or absence of calcification when controlled for gender, initial reflux grade, amount of autologous chondrocytes injected, number of injections used or total followup time from initial injection.Mound calcifications have now been reported after endoscopic therapy for vesicoureteral reflux with autologous chondrocytes as well as dextranomer/hyaluronic acid copolymer. The etiology of these calcifications remains unknown, and it is unclear whether mound calcification after endoscopic treatment will have any associated morbidity in long-term followup. Urologists, patients and other health care providers should be aware that mound calcification is a potential risk after endoscopic treatment of vesicoureteral reflux, and that these calcified mounds may mimic ureterovesical junction stones.
