Purpose: Few studies have quantified differences in histology and implications for survival between male children and adults with germ cell tumors (GCT). We evaluated these differences and associations with cancer-specific survival (CSS) using Surveillance, Epidemiology, and End Results (SEER) cancer registries., Methods: SEER (1988-2016) was used to identify male patients 0 to 40 years of age diagnosed with seminoma and nonseminomatous GCT (NSGCT). Demographic and tumor characteristics were tabulated with histology distributions compared by age group (0-4, 12-18, 19-40 years old). CSS was evaluated in multivariable Cox proportional hazards regression models., Results: Among 27,204 patients identified, 1,538 (5.7%) were pediatric (0-18 years). Seminoma (54.3%) predominated in adult patients (ages 19-40). Among 0 to 4 years-old, yolk sac tumor (71.2%) and teratoma (21.5%) were most common. Mixed GCT (52.7%) was most prevalent among 12 to 18 years-old with seminoma, embryonal, and teratoma occurring in 12 to 15% each. Relative to pediatric patients, adult patients had similar CSS for seminoma but worse CSS for NSGCT on Kaplan-Meier curves with 9 years mean follow-up. Choriocarcinoma and yolk sac tumors carried the worst prognosis relative to seminoma for both children (HR 5.7 and HR 11.1, respectively, both P < 0.01) and adults (HR 4.6 and HR 4.6, respectively, both P < 0.01) adjusted for stage., Conclusion: Histology of GCTs vary by age with yolk sac tumors and teratoma predominating for male patients 0 to 4 years, mixed GCT for 12 to 18 years, and seminoma for 19 to 40 years. Pediatric patients with NSGCT had higher CSS than their adult counterparts. Mixed GCT represented an increasing proportion of GCT over the study period. Age, stage, and histology impact CSS in both pediatric and adult populations., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Introduction: Classic bladder exstrophy (CBE) is a malformation of the genitourinary system that occurs due to failure of abdominal wall closure. Unlike other malformations of similar incidence, prenatal diagnosis of CBE relies on suggested, rather than formal, diagnostic criteria., Objective: This report describes prenatal diagnosis of CBE in the largest single-institutional cohort to date and delineates key sonographic findings and protocols for specialist referral., Materials and Methods: A single-institutional database was reviewed for CBE patients born since 2000. Data on screening ultrasound use, gestational age at ultrasound, and abnormal findings were extracted. Where possible, time of prenatal diagnosis (pre- or postnatal and gestational age), ultrasound findings and other imaging data, specialist referral, institution of birth and closure, and outcome of primary closure attempt were compared., Results: Of 557 patients born with CBE between 2000 and 2022, 284 met inclusion criteria and complete data were available for 280 (229 born domestically and 51 born internationally) who were included for analysis. Abnormal sonography suggestive of CBE was present for 48% (n = 134) of patients, for whom absent bladder was the most common abnormal finding (76% [102/134]). Of domestic patients, 46% (n = 106) were diagnosed prenatally at a median gestational age of 22 weeks (inter-quartile range [IQR]: 20-24), and 14% (n = 32) underwent confirmatory fetal magnetic resonance imaging. Of domestic patients with abnormal prenatal findings, 75% (n = 80/106) consulted with maternal-fetal medicine and 58% (n = 62/106) consulted with pediatric urology. On univariate analysis, prenatal diagnosis was positively associated with primary repair at Association for the Bladder Exstrophy Community-recognized centers of excellence (54% vs. 38%, p = 0.02) and negatively associated with osteotomy at primary closure (41% vs 59%, p = 0.003) but not success of primary closure (74% vs. 82%, p = 0.07)., Discussion: Rates of prenatal diagnosis in this cohort were similar to previous reports of smaller cohorts. Diagnosis allows for comprehensive pre- and postnatal follow-up with a pediatric urologist, with implications on birth planning and decisions on termination of pregnancy. Because of the previously-reported association between exstrophy and in vitro fertilization, these pregnancies should undergo detailed sonography. Any nonvisualization of the fetal bladder should prompt a detailed exam, and any finding characteristic of bladder exstrophy warrants referral to pediatric urology., Conclusions: Although CBE is a rare disorder, it is underdiagnosed during pregnancy. Sonographers and obstetricians should be aware of characteristic findings and best practices following diagnosis. Early referral to pediatric urology and maternal-fetal medicine is important for counseling and postnatal planning., Competing Interests: Conflicts of interest None of the authors have a direct or indirect commercial financial incentive associated with the publication of this article, and the manuscript is not under consideration elsewhere., (Copyright © 2024 Journal of Pediatric Urology Company.

Purpose: Appropriate perioperative management is crucial in patients undergoing classic bladder exstrophy closure (CBE). Therefore, the authors sought to review their intra and postoperative management of patients with CBE undergoing primary closure and examine the impact of this pathway on patient outcomes., Method: A prospectively maintained institutional approved exstrophy-epispadias complex database was reviewed for patients with CBE who had undergone primary closure between 2016 and 2022 and whose closure was performed within one year of age. Electronic medical records for eligible patients were retrospectively reviewed to examine patient demographics, use of pelvic osteotomy, immobilization status, pediatric intensive care unit (PICU) admission and management, perioperative analgesia and sedation, nutritional support, drainage tubes, blood transfusions, antibiotic coverage, hospital length of stay, postoperative complications, and closure failure., Results: A total of 25 patients were identified, 22 with CBE and 3 with variant CBE. Closure was performed at a median age of 84 days with patients ranging in age from 9 to 351 days. All patients underwent osteotomy and immobilization with modified Buck's traction and external fixation for a median duration of 41 days. A suprapubic tube was placed in all patients for a median duration of 46.5 days. All patients underwent PICU admission following closure for a median duration of 8 days. Ventilator support was required in 68 % of patients for a median of 3 days. Epidural analgesia was used in all patients and catheters were maintained for a median duration of 19 days. All patients received a blood transfusion over the course of their admission. Patient-controlled analgesia was used in most patients as an adjunct for a median duration of 38.5 days. Other commonly used analgesic adjuncts included acetaminophen, diazepam, clonidine, and dexmedetomidine. TPN was used in 80 % of patients for a median of 7 days with a return of oral feeding thereafter. Overall, the closure success rate in this cohort of patients was 100 %., Discussion: The outcome of primary bladder closure can have inauspicious consequences that can affect a child's continence for years. The incidence of failed bladder closure can be minimized with the implementation of a detailed plan for immobilization, analgesia, and nutrition guided by an experienced multi-disciplinary team., Conclusion: We have identified several guiding principles for perioperative success in exstrophy patients at our center including Buck's traction with external fixation, provision of adequate postoperative analgesia and sedation, aggressive nutritional support, renal and bladder drainage, and robust antibacterial support. Our high success rate in managing this complex pathology demonstrates its validity and use as a pathway to success., Competing Interests: Conflict of interest The authors have no financial or personal relationships with other people or organizations that could inappropriately influence their work., (Copyright © 2024 Journal of Pediatric Urology Company.

With continued improvements in medical care and surgical reconstruction, more patients with classic bladder exstrophy (CBE) are living into adulthood, than ever before. With improved survival, a greater emphasis on adult issues and improving quality of life (QOL) for these individuals is of increasing importance. This review aims to summarize data on long-term considerations for the adult with exstrophy and to highlight areas of future research and collaboration. Key conclusions are that continence or dryness are achievable alongside the ability to enjoy sexual relationships and a good quality of life., Competing Interests: Conflicts of interest None., (Copyright © 2023 Journal of Pediatric Urology Company.

Introduction: Bladder capacity (BC) is an important metric in the management of patients with classic bladder exstrophy (CBE). BC is frequently used to determine eligibility for surgical continence procedures, such as bladder neck reconstruction (BNR), and is associated with the likelihood of achieving urinary continence., Objective: To use readily available parameters to develop a nomogram that could be used by patients and pediatric urologists to predict BC in patients with CBE., Study Design: An institutional database of CBE patients was reviewed for those who have undergone annual gravity cystogram 6 months after bladder closure. Candidate clinical predictors were used to model BC. Linear mixed effects models with random intercept and slope were used to construct models predicting log transformed BC and were compared with adjusted R 2 , Akaike Information Criterion (AIC), and cross-validated mean square error (MSE). Final model evaluated via K-fold cross-validation. Analyses were performed using R version 3.5.3 and the prediction tool was developed with ShinyR., Results: In total, 369 patients (107 female, 262 male) with CBE had at least one BC measurement after bladder closure. Patients had a median of 3 annual measurements (range 1-10). The final nomogram includes outcome of primary closure, sex, log-transformed age at successful closure, time from successful closure, and interaction between outcome of primary closure and log-transformed age at successful closure as the fixed effects with random effect for patient and random slope for time since successful closure (Extended Summary)., Discussion: Using readily accessible patient and disease related information, the bladder capacity nomogram in this study provides a more accurate prediction of bladder capacity ahead of continence procedures when compared to the age-based Koff equation estimates. A multi-center study using this web-based CBE bladder growth nomogram (https://exstrophybladdergrowth.shinyapps.io/be&#95;app/) will be needed for widespread application., Conclusion: Bladder capacity in those with CBE, while known to be influenced by a broad swath of intrinsic and extrinsic factors, may be modeled by the sex, outcome of primary bladder closure, age at successful bladder closure and age at evaluation., Competing Interests: Conflicts of interest The authors have no financial or personal relationships with other people or organizations that could inappropriately influence their work., (Copyright © 2023 Journal of Pediatric Urology Company.

Background: Following successful closure of patients with classic bladder exstrophy (CBE), the next major milestone is the establishment of urinary continence. Prior to determining the most appropriate continence surgery, it is imperative to reach an adequate bladder capacity minimum of 100 cc in order to make the decision between bladder neck reconstruction (BNR) or continent stoma, with or without augmentation cystoplasty (AC)., Objective: To examine the timing of when patients achieve threshold bladder capacity for BNR eligibility. We hypothesize most patients will achieve an adequate bladder capacity (100 cc) by 7 years old when continence surgeries will begin to be considered., Study Design: An institutional database of 1388 exstrophy patients was retrospectively reviewed for CBE patients after successful primary bladder closure. Bladder capacities were measured via gravity cystography and data presented as descriptive statistics. The cohort was stratified by location, neonatal (≤28 days) or delayed closure period and osteotomy status. The bladder capacities were categorized to either reaching goal or not and a cumulative event analysis was performed. The event being reaching 100 cc capacity or greater and time being the number of years between bladder closure and attainment of goal capacity., Results: 253 patients met inclusion criteria between 1982 and 2019. The majority were of male gender (72.9%), had their closure performed at the authors' institution (52.5%), within the neonatal period (80.7%), and without an osteotomy (51.7%). 64.9% of patients reached goal bladder capacity. There were no significant differences in those who did or did not achieve goal except for clinical follow up. Cumulative event analysis demonstrated a median time of 5.73 years (95% CI 5.2-6.20) corresponded with a 50% event probability of reaching goal capacity. Cox-proportional hazards showed location of closure was significantly associated with hazards of reaching goal bladder capacity (HR = 0.58, CI 0.40-0.85, p = 0.005). Based on this model, the median time to event would be 5.20 years (95% CI 4.76-5.80) for cases done at the authors' hospital and 6.26 years for those performed at an outside hospital (95% CI 5.77-7.24)., Conclusions: These findings help surgeons counsel families appropriately on the odds of attaining goal capacity at various ages. For those who do not reach 100 cc by five years of age, it helps further characterize the odds of requiring a continent stoma with bladder augmentation and the best timing for reconstructive surgery in order to safely gain urinary continence. Families may also be assured that most patients would have the breadth of surgical options when it comes to continence as more than half of patients reached the bladder capacity threshold., Competing Interests: Conflicts of interest The authors have no financial or personal relationships with other people or organizations that could inappropriately influence their work., (Copyright © 2023 Journal of Pediatric Urology Company.

Introduction: Bladder exstrophy (BE), cloacal exstrophy (CE), and epispadias (E) are variants of the exstrophy-epispadias complex (EEC). These children require opioids and benzodiazepines to achieve pain management and immobilization for a lifetime of surgeries. It is hypothesized that these children would be sensitized to opiates and benzodiazepines as adults. The objective was to identify incidence of opiate and benzodiazepine use in adult EEC patients., Methods: A US Health network, TriNetX Diamond was queried from 2009 to 2022. Incidence of prescriptions for benzodiazepines and opioids were calculated for adults aged 18-60 years with a diagnosis of BE, CE, or E., Results: A total of 2627 patients were identified: 337 with CE, 1854 patients with BE, and 436 with E. Of these, 55.5% of CE, 56.4% of BE, and 41.1% of E had received any opioid prescription. Non-EEC controls had lower rates of opioids at 0.3%. E had a lower likelihood than BE or CE of receiving opioids (p < 0.0001, p < 0.0001). Benzodiazepines were prescribed in 30.3% of CE, 24.4% of BE, 18.3% of E, and 0.1% of controls. CE had a higher likelihood of benzodiazepines than both BE and E (p = 0.022, p < 0.001, respectively). E group had the lowest likelihood of benzodiazepine prescription (p = 0.007 when compared to BE) and all groups were significantly higher than controls (p < 0.0001 for all comparisons). For BE, females were more likely to be prescribed opioids (p = 0.039) and benzodiazepines (p = 0.027) than males. Sub-analyses revealed BE females had higher rates of surgical procedures (general, cardiac, gastrointestinal, and maternity) and chronic diagnoses (generalized anxiety disorder, major depressive disorder, chronic pain) compared to males with BE. Older age was associated with higher likelihood of opioid or benzodiazepine prescriptions in BE (p < 0.001), CE (p = 0.004), and E (p = 0.002)., Discussion: Across the EEC, adult patients with the most severe anomalies of CE were more likely to have received opioids and benzodiazepines. Females with BE were prescribed more opioid and benzodiazepines than males with BE. Mirroring the US population, female sex and increasing age were associated with higher rates of prescriptions, chronic diagnoses, and surgical procedures. Limitations include the lack of granular data and ability to correlate results with childhood surgeries., Conclusion: Adult EEC patients have higher rates of opioid and benzodiazepine prescriptions, with a high percentage of co-prescribing when compared to healthy controls. Across the spectrum, those with more severe anomalies, female sex, and increasing age were more likely to have received prescriptions., Competing Interests: Conflicts of interest None., (Copyright © 2023 Journal of Pediatric Urology Company.

Introduction: Restoration of genitourinary anatomy with functional urinary continence is the reconstruction aim is the exstrophy-epispadias complex (EEC). In patients who do not achieve urinary continence or those who are not a candidate for bladder neck reconstruction (BNR), bladder neck closure (BNC) is considered. Interposing layers including human acellular dermis (HAD) and pedicled adipose tissue are routinely placed between the transected bladder neck and distal urethral stump to reinforce the BNC and minimize failure due to fistula development from the bladder., Objective: The aim of this study was to review classic bladder exstrophy (CBE) patients who underwent BNC to identify predictors of BNC failure. Specifically, we hypothesize that increased operations on the bladder urothelium leads to a higher rate of urinary fistula., Study Design: CBE patients who underwent BNC were reviewed for predictors of failed BNC which was defined as bladder fistula development. Predictors included prior osteotomy, interposing tissue layer use and number of previous bladder mucosal violations (MV). A MV was defined as a procedure when the bladder mucosa was opened or closed for: exstrophy closure(s), BNR, augmentation cystoplasty or ureteral re-implantation. Predictors were evaluated using multivariate logistic regression., Results: A total of 192 patients underwent BNC of which 23 failed. Patients were more likely to develop a fistula with a wider pubic diastasis at time of primary exstrophy closure (4.4 vs 4.0 cm, p=0.0016), have failed exstrophy closure (p=0.0084), or have 3 or more MVs before BNC (p=0.0002). Kaplan-Meier analysis of fistula-free survival after BNC, demonstrated an increased fistula rate with additional MVs (p=0.0004, Figure 1). MVs remained significant on multivariate logistic regression analysis with a per-violation odds ratio of 5.1 (p<0.0001). Of the 23 failed BNC's, 16 were surgically closed including 9 using a pedicled rectus abdominis muscle flap which was secured to the bladder and pelvic floor., Conclusion: This study conceptualized MVs and their role in bladder viability. Increased MVs confer an increased risk of failed BNC. When considering BNC, CBE patients with 3 or more prior MVs may benefit from a pedicled muscle flap, in addition to HAD and pedicled adipose tissue, to prevent fistula development by providing wellvascularized coverage to further reinforce the BNC., Competing Interests: Conflicts of interest The authors have no financial or personal relationships with other people or organizations that could inappropriately influence their work., (Copyright © 2023 Journal of Pediatric Urology Company.

Introduction: The authors aim to compare single institutional 30-day complication rates between delayed and neonatal closure of classic bladder exstrophy (CBE)., Materials and Methods: An institutional database of 1415 exstrophy-epispadias patients was reviewed retrospectively for CBE patients who underwent primary closures at the authors' institution between 1990 and 2020. Patients were identified as having received either neonatal or delayed (at age >28 days) closures. All 30-day complications were recorded, including wound infection and dehiscence, genitourinary and non-genitourinary infections, bowel obstruction, blood transfusions, and others. Descriptive statistics were performed to summarize patient level data. Categorical variables were reported by count and percentages and were compared using Exact Cochran-Armitage trend analysis by decade, or with Fisher's Exact Test and Chi-square test when directly comparing categories and outcomes. Continuous variables were analyzed via Mann Whitney U and one-way ANOVA as appropriate., Results: The cohort included 145 patients: 50 delayed and 95 neonatal closures. The total complication rate was 58% in delayed closures compared to 48.4% for neonatal closures (p = 0.298), with the majority being Clavien-Dindo grade I or II. Excluding blood transfusion, complication rates fell to 26% and 34.7% in delayed and neonatal closures, respectively (p = 0.349). The most common single complication was unplanned post-operative blood transfusion (38% delayed; 26.3% neonatal; p = 0.34), followed by pyelonephritis (2% delayed; 8.4% neonatal), and urinary fistula (6% delayed; 1.1% neonatal). Grade III Clavien-Dindo complications occurred in 2% delayed and 7.4% neonatal groups (n = 1; n = 7 respectively; p = 0.263). A single delayed patient had grade IV complications compared to three neonatal patients (p = 0.66)., Conclusions: Delayed primary closure has become a frequently performed alternative in the modern treatment of bladder exstrophy for patients who do not undergo newborn closure because of prohibitive circumstances or surgeon's discretion. The majority of the complications associated with delayed closure are a low Clavien-Dindo grade and easily managed during the postoperative inpatient hospital stay. Families should be counseled about the possibility of minor, conservatively managed complications and likelihood of a blood transfusion with osteotomy., (Copyright © 2023 Journal of Pediatric Urology Company.

Purpose: A pivotal factor in the success of bladder closure in patients with classic bladder exstrophy (CBE) is the postoperative immobilization of the pelvis and lower extremities after pelvic osteotomy. This study investigates the outcomes of closure among patients with lower limb immobilization using many techniques. The authors hypothesize that the addition of external fixation (pelvic immobilization) in patients with any form of limb immobilization will be associated with improved outcomes., Methods: A prospectively maintained institutional exstrophy-epispadias complex database of 1415 patients was reviewed for patients with CBE who had undergone closure with available immobilization and osteotomy data. Association between closure outcomes and immobilization techniques were determined. Univariate analysis was performed using Chi-Square or Fischer-Exact test as appropriate for categorical variables. Multivariate analysis via binomial logistic regression was used to identify factors leading to successful closure., Results: A total of 747 closure events matching the inclusion criteria were identified. Patients included 508 males and 239 females. There were 597 primary closures (79.9%) with 150 reclosure events (20.1%). Limb immobilization was used in 627 (83.9%) of closure events. Successful closures were associated with osteotomy use (p < 0.0001) and limb immobilization (p < 0.0001); specifically, the combined anterior innominate with posterior vertical iliac osteotomy and modified Buck's traction with external fixation (p < 0.0001, p < 0.0001). Among the group of 33 patients who received external fixation alone and no other type of immobilization, the failure rate was 33.3%, comparatively, patients with any form of combined immobilization (external fixation with lower limb immobilization) had a failure rate of 7.1% ( Table 1). Among patients immobilized with mummy wrap, spica casting, or knee immobilizers, external fixation was associated with 3.76 increased odds of successful closure (p = 0.0005, 95% CI 1.79-7.90). In a unique group of 67 patients without pelvic osteotomy or any form of pelvic or limb immobilization, the failure rate was 74.6%., Discussion: This study confirms, in a larger series, previous findings of improved outcomes when patients are immobilized with modified Buck's traction and external fixation. The authors apply this technique in most all closures and recommend this technique be utilized whenever feasible. However, regardless of the manner of lower limb immobilization, external fixation is a critical factor to optimize closures and ensure success., Conclusion: The results of this study clearly suggest the use of external fixation can be protective against bladder closure failure. The use of pelvic immobilization, in addition to post-operative lower limb immobilization should be strongly considered., (Copyright © 2023 Journal of Pediatric Urology Company.

Introduction and Objective: The bladder exstrophy-epispadias complex (BEEC) is a rare spectrum of congenital genitourinary malformations with an incidence of 1:10,000 to 1:50,000. Advances in reconstructive surgical techniques have improved clinical outcomes, but there is a paucity in data about disease sequela in adulthood. This is the largest survey to date in the United States exploring the urinary continence, bladder management, and oncologic outcomes in adults with BEEC., Methods: Respondents were over the age of 18 with a diagnosis of bladder exstrophy, cloacal exstrophy, or epispadias. They were treated at the authors' institution, included in the Association for the Bladder Exstrophy Community (A-BE-C) mailing list, and/or engaged in A-BE-C social media. A survey was created using uniquely designed questions and questionnaires. Survey responses between May 2020 and July 2020 were processed using Research Electronic Data Capture (REDCap). Quantitative and qualitative statistics were used to analyze the data with significance at p < 0.05., Results: A total of 165 patients completed the survey. The median age was 31.5 years (IQR 25.9-45.9). Many patients considered themselves continent of urine, with a median satisfaction score of 74 (IQR 50-97) on a scale from 0 (consider themselves to be completely incontinent) to 100 (consider themselves to be completely continent). There was less leakage among those with a continent urinary diversion compared to those who void or catheterize per urethra (p = 0.003). Patients with intestinal-urinary tract reconstruction, such as augmentation cystoplasty or neobladder creation, were more likely to perform bladder irrigations (p = 0.03). Patients with continent channels were more likely to report UTI than all other forms of bladder management (89.0% vs. 66.2%, p = 0.003). Three (1.9%) patients were diagnosed with bladder cancer. A small portion of patients (27.2%) were given bladder cancer surveillance recommendations by a physician., Discussion: Most patients achieved a satisfactory level of urinary continence, with the highest continence rates in those with a continent urinary diversion. Those with intestinal-urinary tract reconstruction were more likely to perform bladder irrigations, perhaps to avoid complications from intestinal mucous production. The rates of self-reported UTI and were higher in patients with continent channels, but recurrent UTIs were not affected by the type of genitourinary reconstruction. Bladder cancer exists in this population, highlighting the need for long-term follow-up., Conclusion: Most BEEC patients achieve a satisfactory level of urinary continence, with the best outcomes in those with a continent urinary diversion. This population requires long-term follow-up with a transitional urologist to ensure adequate oncologic care., Competing Interests: Conflicts of interest The authors have no conflicts of interest to disclose., (Copyright © 2022 Journal of Pediatric Urology Company.

Introduction: In patients with classic bladder exstrophy (CBE), posterior urethral strictures after primary bladder closure can be difficult to manage and therefore necessitate alternative techniques in reconstruction of the proximal urethra. There is a paucity of literature describing treatment and management of posterior urethral stricture arising after repair of classic bladder exstrophy., Objective: To describe the technique of a bladder neck reconstruction (BNR) with a modified Tanagho anterior detrusor flap in the treatment of posterior urethral stricture arising after repair of classic bladder exstrophy., Patients and Methods: A prospectively maintained, IRB-approved database of 1401 exstrophy-epispadias patients was reviewed for patients who underwent bladder neck or proximal urethral reconstruction with modified Tanagho flap for proximal urethral stricture disease from the time period of 1975-2021. A total of 5 patients (1 female and 4 males) with classic bladder exstrophy who underwent proximal urethral reconstruction with modified Tanagho flap were identified. Of these 5 patients, the 1 female patient was treated for ongoing incontinence, not posterior urethral stricture, and was thus excluded from this report. Outcomes measured included post operative bladder capacity, post-operative continence status, upper urinary tract status, and stricture recurrence., Results: Four male patients with CBE were treated for posterior urethral strictures and are reviewed here. Three patients underwent successful primary closure (1 via modern staged repair of exstrophy (MSRE) and 2 via complete primary repair of exstrophy (CPRE)), and 1 patient (MSRE) required repeat closure at the time of stricture repair. Mean age at BNR Tanagho flap was 3.8 (range 2.3-5.0) years. All patients remained stricture free with post-operative urinary incontinence; 2 patients underwent subsequent elective bladder neck transection to achieve continence. Mean follow up 9.9 (range 2.1-15.6) years., Discussion: All 4 patients had excellent long term success rates, comparable to results reported in several adult studies utilizing a modified Tanagho flap in women with post-traumatic bladder neck contractures. In addition, our technique described here shares similarities with both the originally described Tanagho flap as well as with a dorsal onlay graft urethroplasty., Conclusion: In this limited series, modified Tanagho flap reconstruction is effective in treating posterior urethral stricture disease in CBE. This technique adds a valuable adjunct to the armamentarium of surgical options for this difficult to manage condition., Competing Interests: Conflicts of interest The authors have no financial or personal relationships with other people or organizations that could inappropriately influence their work., (Copyright © 2022 Journal of Pediatric Urology Company.

Introduction: The penis in exstrophy-epispadias complex (EEC) males is diminutive and patients are often dissatisfied with appearance and length. Due to an increased risk of psychosexual dysfunction, patients desire penile reconstruction. Surgical options include penile lengthening with a full thickness skin graft (SG) or tissue expansion (TE) used for cutaneous coverage or neophalloplasty using a radial forearm free flap or pedicled antero-lateral thigh flap., Objective: The aim of this study was to assess sexual health outcomes before and after SG or TE assisted lengthening and neophalloplasty., Study Design: Patients aged 18 years or older, who underwent penile reconstruction were identified using an institutionally approved database of EEC patients. Patient perception of penile appearance, sexual function, their frequency of sexual intercourse and overall satisfaction with reconstruction were assessed using a survey consisting of validated and non-validated questions., Results: Eighty-three patients underwent penile reconstruction, 57 met the inclusion criteria and 28 responded to the survey (49.1%). Fourteen were reconstructed using a SG, 6 with TE and 8 underwent neophalloplasty. Median time from reconstruction to survey completion was 4.4 years (range 1.2-13.2) Four patients had a diagnosis of epispadias, 1 cloacal exstrophy, 23 classic bladder exstrophy (CBE). Before reconstruction patients were dissatisfied with their penile appearance with a median penile perception score of 4.5 compared to 7.5 after surgery (p = 0.0034, Fig. 1). Twenty-three patients were dissatisfied with penile length, with 18 reporting an improvement following reconstruction (p = 0.0002). There was no correlation in time after reconstruction with PPS or satisfaction with penile length (p = 0.86 and p = 0.55, respectively). Overall, the median Sexual Health Inventory for Men (SHIM) score was 19, with no difference between the surgical groups (p = 0.33). Nine patients engaged in sexual intercourse before reconstruction which increased to 17 afterwards., Conclusion: All three surgical methods improved patient perception of penile appearance and length. Patients who previously never engaged in intercourse were able to and those who had were doing so more frequently, of which a greater proportion were in a relationship. The results are encouraging though must be interpreted with caution due to the small number of responders and possible risk of bias. These findings provide vital information for future patients and routine psychological assessment will help manage patient expectations to improve satisfaction., Competing Interests: Conflict of interest None., (Copyright © 2022 Journal of Pediatric Urology Company.

Background: The addition of pelvic osteotomy to the armamentarium of tools for correction of classic bladder exstrophy (CBE) and cloacal exstrophy (CE) has undeniably served as one of the most effective advancements in improving the likelihood of successful primary bladder closure. Osteotomy-related complications have been studied and documented extensively in patients with CBE, yet evaluation remains limited in CE concordant with its relative rarity., Objective: To compare orthopedic complications in patients with CBE and CE who underwent primary bladder closure with osteotomy., Methods: A prospectively maintained, IRB-approved database of 1401 exstrophy-epispadias patients was reviewed for patients with CBE or CE after primary closure and pelvic osteotomy performed at a single institution from 1975 to 2021. Failed closure was defined as dehiscence, bladder prolapse, or vesicocutaneous fistula at any point. Surgery or anesthesia-related complications were captured within 6 weeks of osteotomy or closure., Results: A total of 146 patients were included in the analysis with 109 and 37 patients with CBE and CE, respectively. Between the CBE and CE cohorts, there were significant differences in median age at primary closure (68 days [IQR 10-260] vs 597 [448-734]; p < 0.001), diastasis width (4 cm IQR [3.8-4.6] vs 6.1 [5.0-7.2]; p < 0.001), osteotomy at time of closure (99.1% vs 75.7%; p < 0.001), and utilization of external hip fixation (67.9% vs 89.2%; p = 0.011). There was no significant difference by gender, osteotomy technique, or hip immobilization technique. Regarding exstrophy closure outcomes, there were 5 failures in the CBE group and 1 in the CE group (p = 1.000). Complications were experienced in 38.5% and 56.8% of CBE and CE patients (p = 0.054) with a significant difference in orthopedic complications (primarily consisting of superficial pin-site infections) between the cohorts (4.6% vs 16.2%, p = 0.031). There was no significant difference in grade 3 or higher complications between cohorts (5.5% vs 13.5%, p = 0.147)., Discussion: This was the first study comparing orthopedic complications after osteotomy between CBE and CE, providing valuable insight into which factors vary among cohorts and which are associated with increased complication rates. Despite availability of high case numbers for these rare disorders, the analysis continued to be limited sample size and missing data for retrospective analysis., Conclusions: While exstrophy closure success and overall complications rates are similar in patients with CBE and CE, patients with CE experience more superficial pin-site infections after pelvic osteotomy. External hip fixation may be associated with the increase in orthopedic complications, though further research is required to elucidate the underlying cause of these complications., (Copyright © 2022 Journal of Pediatric Urology Company.

Introduction: Pelvic osteotomy is indicated in classic bladder exstrophy (CBE) patients with a wide pubic diastasis or non-malleable pelvis. While the safety of pelvic osteotomy in delayed and failed closures is established, there remains less clarity on their safety in newborns. The authors herein sought to present their experience with CBE patients who underwent pelvic osteotomy for assistance with bladder closure during both the newborn and delayed time periods., Objective: The authors hypothesize that pelvic osteotomy during exstrophy closure may be performed safely in newborns with few perioperative or post-operative negative sequelae., Study Design: A prospectively maintained IRB-approved database was reviewed for CBE patients who underwent osteotomy during primary closure. Patient demographics, performing institution (authors' or outside), closure outcome, diastasis width, and post-operative complications were noted. Patient subgroups included newborn and delayed (>28 days of life) closures. Failure was defined as bladder dehiscence, prolapse, outlet obstruction, or vesicocutaneous fistula requiring reoperation. Orthopedic complications included nerve palsies, superficial pin-site infection, and bladder neck erosion by orthopedic hardware. Analyses were performed using a Chi-square test., Results: 286 patients were included: 186 newborn and 100 delayed closures. The authors' institution performed 109 cases (44 newborn and 65 delayed). Within the overall newborn closure cohort, no significant differences were found in outcomes among the osteotomy types with success rates of 80%, 60.8%, and 71.4% in the combined, posterior iliac, and anterior innominate groups, respectively (p = 0.24). In the delayed group, success rates were significantly different with rates of 100%, 72.4%, and 93.8% in the combined, posterior iliac, and anterior innominate groups, respectively (p < 0.001). Febrile urinary tract infection (UTI) was the most common complication at 8% (23/286). Only 1.7% (5/286) of patients had orthopedic complications with 3 patients in the newborn cohort, 2 patients in the delayed cohort, and only one patient requiring reoperation., Discussion: Orthopedic complications are rare in CBE patients who undergo osteotomies regardless of the closure period. No clinically significant difference in orthopedic complication rate was found between newborn and delayed closure periods., Conclusions: While current trends have moved toward delayed primary closures, there remains a role for osteotomy during exstrophy closure in select newborn patients and can be performed safely with few complications., Competing Interests: Conflicts of interest None., (Copyright © 2021 Journal of Pediatric Urology Company.

Introduction: With current trends towards delaying the closure of classic bladder exstrophy (CBE), bladder growth rate or ultimate capacity may be impacted., Objective: To examine consecutive bladder capacities in CBE patients who had primary closures at differing ages and determine whether there is an optimal age for closure, with reference to bladder capacity., Study Design: A retrospective review was performed using an institutional database., Inclusion Criteria: CBE, successful neonatal (i.e. ≤28 days old) or delayed (i.e. >28 days old) primary closure, at least three consecutive bladder capacities or two measures taken 18 months apart, and first bladder capacity measured ≥3 months after closure. Only capacities prior to continence surgery and before 14 years of age were considered. Two cohorts were created: neonatal and delayed closure. To account for repeated measurements per patient, a linear mixed model evaluated effects of age and length of delay on bladder capacity based on closure cohort. Individuals in the delayed closure group were further stratified into quartiles to assess for detriment to the bladder based on length of delay., Results: The cohort included 128 neonatal and 38 delayed patients. Median age at closure for the delayed group was 193 days (IQR 128-299). Based on univariate analysis, for the first three capacity measurements, the delayed group had significantly lower capacities despite having a similar median age when the measurements were taken. Linear mixed effects model showed significantly decreased total bladder capacity in delayed closure compared to neonates. The 2nd and 4th quartile groups had the most significant decreases in capacity., Discussion: Time points for the most significant decline appear after the 2nd and 4th quartiles, representing 4-6 months and beyond 9 months, respectively. From this, the authors theorize that the appropriate time to close an exstrophy patient is as early as possible (1st quartile), or, if a delay is needed for growth of a bladder template, then between 6 and 9 months (3rd quartile). There may be a detriment to growth rate, however, statistical power may be lacking to discern this. Study limitations include the single-centered, retrospective design. However, results described here fill an important deficit in the knowledge of managing CBE., Conclusions: All patients in the delayed bladder closure group demonstrated a decline in bladder capacity compared to the control neonatal closure group, with significant differences in the 2nd and 4th quartiles. Thus, closing the bladder prior to nine months of age is recommended., Competing Interests: Conflicts of interest The authors have no financial or personal relationships with other people or organizations that could inappropriately influence their work., (Copyright © 2020 Journal of Pediatric Urology Company.

Introduction: Repair of classic bladder exstrophy (CBE) is known to alter dimensions of the bony pelvic ring. Pelvic volume and acetabular configuration are additional metrics which merit analysis in the reconstruction process. Advances in magnetic resonance imaging (MRI) allow for precise elucidation of such anatomy in pediatric patients, providing enhanced knowledge of how primary reconstruction may impact factors in pelvic health., Methods: An IRB-approved exstrophy-epispadias database of 1337 patients was reviewed for patients with CBE who had pelvic MRI performed before and after repair. Pelvic MRIs were analyzed by a pediatric radiologist, and three-dimensional volumetric renderings of the true pelvis were calculated. Pre- and post-closure imaging were compared, in addition to imaging from age-matched controls without pelvic pathology. Cartilaginous acetabular index and version angles were also calculated and compared between groups., Results: Eighteen patients with post-closure imaging, 14 of whom also had pre-closure imaging, and 23 control patients (ages 0-365 days) were included. The median ages at pre- and post-closure scan were 2 and 178 days, respectively. Osteotomy was performed in 6 (33%) of the closures. The median segmented pelvic volumes were 89 cm 3 in the pre-closure group, 105 cm 3 in the post-closure group, and 72 cm 3 in the control group. At a given age, patients with CBE pre-closure had the largest pelvic volume, and those without bladder exstrophy demonstrated the smallest pelvic volumes (Summary Figure). CBE patients' pelvic volumes were overall lower following repair, relative to age (p = 0.007). Cartilaginous acetabular version angle increased following closure, with acetabular orientation converting from retroversion to anteversion in all cases. However, only acetabular version angles were significantly different between groups., Discussion: This study found that pelvic volume significantly decreased relative to age following primary repair of CBE, but that it did not correct to control levels. Similarly, acetabular retroversion that is naturally seen in exstrophy patients was converted to anteversion post-closure but did not become completely normal. Knowledge of these persistent anatomical anomalies may be useful in treatment of future concerns related to exstrophy, such as continence achievement, pelvic organ prolapse, and potential gait disturbances. Lack of significant differences between study groups regarding acetabular index angles can give assurance to providers that hip dysplasia is neither a natural concern nor iatrogenically inflicted through reconstruction., Conclusions: The primary closure of exstrophy results in pelvic volumes and anteverted acetabula that more closely resemble those without bladder exstrophy, compared to pre-closure findings., Competing Interests: Conflict of interest The authors have no financial or personal relationships with other people or organizations that could inappropriately influence their work., (Copyright © 2020 Journal of Pediatric Urology Company.

Background: Men born on the bladder exstrophy-epispadias complex (BEEC) spectrum may undergo neophallus reconstruction with a variety of free flaps, most commonly radial forearm. In order to achieve erectile function, a penile prosthesis may be inserted following neophallus construction., Objective: In this study, we sought to describe the perioperative and clinical outcomes of inflatable penile prosthesis (IPP) insertion into neophalluses of patients along the BEEC spectrum., Study Design: Using a prospectively maintained institutional BEEC database, patients who had undergone both neophallus creation and IPP placement were identified for this study. Surgery was performed by two surgeons with expertise in IPP implantation. Operative details and postoperative outcomes and complications were collected with review of the medical record., Results: Overall, there were a total of 13 men who underwent neophallus reconstruction with subsequent IPP placement. Of these men, 76.9% (10/13) had experienced successful primary closure in childhood. One patient had corporal loss secondary to complete primary repair of exstrophy (CPRE) following a failed primary attempt. The average age at IPP placement was 23.2 years (SD ± 5.06). Mean OR time (n = 11) was 244.8 min (SD ± 46.2). 76.9% (10/13) of the cases used AlloDerm™ as a neotunica albuginea for support of the IPP. Three patients (23.1%) experienced complications all of which required revision surgery. Two of these complications were erosions in patients for whom AlloDerm™ was not used in the initial IPP placement., Discussion: The results of this study suggest that IPP placement in neophalluses of males on the BEEC spectrum have low perioperative and postoperative morbidity with successful outcomes. While the rate of complications is notably higher in this group compared to the native penis IPP literature, the use of AlloDerm™ or other allograft materials may help to narrow this gap., Conclusions: IPP placement in neophalluses of men on the BEEC spectrum is successful in the majority of cases. Complications may be reduced with the use of AlloDerm™ in initial placement., Competing Interests: Conflicts of interest The authors have no conflicts of interest to disclose., (Copyright © 2020.

Introduction: Several surgical methods have been used for primary repair of bladder exstrophy in the newborn. Complete primary repair of exstrophy (CPRE) aims to prevent the need for surgeries beyond the newborn period. Due to the rarity of bladder exstrophy, it has proven difficult in the past to analyze whether use of this method of closure truly does confer acceptable continence outcomes and hence minimizes the requirement for additional surgeries later in life., Objective: To describe the continence outcomes of CPRE patients who went on to receive bladder neck reconstruction (BNR), and secondarily, to compare clinical features between those patients who were able to receive undergo a BNR compared to those who were not., Study Design: An IRB approved database of 1330 exstrophy-epispadias patients was used to identify referred patients after successful CPRE for management of continued urinary incontinence. Urinary continence outcomes were assessed in those who underwent modified Young Dees Leadbetter BNR following CPRE., Results: Sixty-one patients were referred for treatment after successful CPRE between 1996 and 2016. None developed continence or a dry interval after primary closure. Of these, forty-two (68.9%) underwent BNR by a single surgeon at a mean age of 5.8 years (range 5-8.4). The mean bladder capacity at BNR was 147 mL (range 102-210 mL). Twenty-five (59.5%) achieved day and night continence, 7 (16.7%) gained daytime continence with nocturnal leakage, and 10 (23.8%) remain totally incontinent. Mean follow-up after BNR was 5.9 years. Combined CPRE and pelvic osteotomy were performed in 100% of patients who were continent and 75% of those who were daytime dry. No continent patient had a ureteral reimplantation before BNR, whereas 4 patients with daytime continence and nocturnal leakage and 7 patients who remained continuously incontinent did., Discussion: This is the largest known series of BNRs in exstrophy patients closed by CPRE. Previous smaller studies have demonstrated mild to moderate success rates of BNR after CPRE, with many patients still requiring additional continence surgeries. The present study found similar results, with additional indication that successful primary closure and use of pelvic osteotomies may correlate with enhanced continence. This study includes outcomes from a single surgeon, with a maximum length of follow up of 13 years., Conclusions: CPRE alone often does not render patients continent of urine, based on the authors' referral population. However, following BNR continence rates in this subgroup were found to reach 76%. Surgeons who treat this population should keep these factors in mind when planning continence surgeries., (Copyright © 2020. Published by Elsevier Ltd.)

Introduction: While evaluation and management options for classic bladder exstrophy (CBE) patients are numerous and varied, little is known regarding the relative utilization of these different methods throughout the world. A large group of exstrophy surgeons practicing globally was surveyed, seeking to document their methods of care., Methods: A list of international exstrophy surgeons' email addresses was compiled using professional contacts and referral networking. An online survey was sent to each email address. Surgeons who had not performed a CBE closure within the previous 5 years were excluded. Survey questions queried the respondents' surgical practice type, years since training, and their preferred methods of preoperative evaluation, operative management, and postoperative management. Survey invitations were sent out starting in December 2014 and responses were collected for approximately 6 months., Results: A total of 1152 valid email addresses were invited, resulting in 293 respondents (25%) from 39 countries and every American Urological Association (AUA) section. Seventy-six were excluded, leaving 217 respondents (Table). Respondents reported a median of 17 years since finishing their surgical training (IQR 8-25 years). Practice types included pediatric urology (n = 209), general urology (n = 9), pediatric surgery (n = 59), and other practice makeup (n = 3). On subgroup analyses, there were no significant regional practice differences, with the exception of complete primary repair of exstrophy (CPRE) and oral opioid prescribing being significantly higher in North America compared to other regions., Discussion: Findings indicate that there may be diversity in CBE practice patterns globally. While most responding surgeons from regions outside of North America indicated modern staged repair of exstrophy (MSRE) as their preferred closure technique, a relatively equal distribution of respondents from North America selected CPRE and MSRE. A majority of North American surgeons chose performing osteotomies for both newborn and delayed closures, while an appreciable number of respondents from other regions selected never using osteotomies in their closures. Limitations to this study include a low survey response rate, particularly from surgeons outside of the United States, which may have significantly impacted the ability to draw meaningful global comparisons., Conclusions: Global variation among practices of surgeons performing CBE closures may exist. The wide range of methods demonstrated by this survey suggests the need for more conclusive comparative studies to elucidate whether an optimal standard exists. Local social factors, access to surgical expertise and transportation to referral centers, and finances play a role in what constitutes the best operative approach., Competing Interests: Declaration of competing interest None., (Copyright © 2020 Journal of Pediatric Urology Company.
