Objective: the primary correction of male epispadias consists of multiple surgical steps: isolation of the complex corpora-urethral plate, bladder neck plasty if incontinence is associated, tubularization of the urethral plate, correction of dorsal curvature, and skin coverage of the penile shaft. The present video demonstrates our center experience in managing incontinent male epispadias and addresses the above-mentioned technical details to achieve the best possible cosmetic and functional result. In particular, the bladder neck plasty through perineal approach, the correction of curvature by external rotation of the corpora and the penile shaft coverage with rotational skin flap Patient and surgical procedure: a 3-year-old boy was born with an isolated incontinent penopubic epispadias. The epispadias was repaired starting with the isolation of the corpora-urethral plate complex using disassembly technique and external rotation of both corpora to fix the dorsal chordee. In addition, the bladder neck was funneled to treat the incontinence. Dorsal skin coverage was achieved using penile skin rather than the redundant ventral prepuce. Result: the boy had an excellent outcome with no urethrocutaneous fistula or recurrence of dorsal chordee at one-year follow-up post-surgery. Conclusion: the described surgical steps allowed dorsal skin closure using the lateral rotation of ventral penile skin flap to improve cosmesis after epispadias repair and avoid the recurrence of chordee secondary to midline dorsal scarring

Introduction: Lower urinary tract dysfunction (LUTD) in cerebral palsy (CP) and other neuromuscular diseases can present with chronic retention that leads to hydronephrosis, recurrent urinary tract infections (UTI), and stone formation. Whenever the conservative treatment of LUTD fails for any reason, it is considered to be complicated LUTD, in which a surgical approach is warranted. Cutaneous vesicostomy (CV) is a simple, well-tolerated, and potentially reversible procedure that protects the upper tracts. We describe our experience using CV for this complex population., Materials and Methods: Children with CP and other neuromuscular diseases admitted to pediatric long-term care units for palliative care between 2015 and 2019 were included in the study. They present multi-system involvement, polypharmacy, and Gross Motor Function Classification System levels of 4 or 5. We retrospectively studied this population's indications and results of CV., Results: Of the 52 admitted patients, 18 presented LUTD with UTI ( n :18; 100%), stones ( n :5; 28%), progressive hydroureteronephrosis ( n :3; 17%), or stones ( n :2; 11%). Conservative initial management (catheterizations, prophylaxis antibiotics) was effective in half the cases. The remaining nine were defined as complicated LUTD and underwent CV. After a mean follow-up of 11.3 months, the follow-up showed improved hydronephrosis in all nine (100%) patients. Recurrent UTIs were no longer seen in eight of nine patients, although three patients required bladder irrigations; bladder stones did not recur after CV; the kidney stones needed further intervention. Revision of the CV was required in two (11%) cases at 12 and 24 months postoperatively due to stoma stenosis., Conclusion: CV is a relatively simple and effective procedure representing a pragmatic solution for managing complicated LUTD in complex long-term institutionalized pediatric palliative care patients with neuropathic bladders., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Vallasciani, Al Saeedi, Khalil, Mohamed, Muneer, Abdelmaguid and Pippi Salle.)

Introduction: The radiographic grading of voiding cystourethrogram (VCUG) images is often used to determine the clinical course and appropriate treatment in patients with vesicoureteral reflux (VUR). However, image-based evaluation of VUR remains highly subjective, so we developed a supervised machine learning model to automatically and objectively grade VCUG data., Study Design: A total of 113 VCUG images were gathered from public sources to compile the dataset for this study. For each image, VUR severity was graded by four pediatric radiologists and three pediatric urologists (low severity scored 1-3; high severity 4-5). Ground truth for each image was assigned based on the grade diagnosed by a majority of the expert assessors. Nine features were extracted from each VCUG image, then six machine learning models were trained, validated, and tested using 'leave-one-out' cross-validation. All features were compared and contrasted, with the highest-ranked then being used to train the final models., Results: F1-score is a metric that is often used to indicate performance accuracy of machine learning models. When using the highest-ranked VCUG image features, F1-scores for the support vector machine (SVM) and multi-layer perceptron (MLP) classifiers were 90.27 % and 91.14 %, respectively, indicating a high level of accuracy. When using all features combined, F1 scores were 89.37 % for SVM and 90.27 % for MLP., Discussion: These findings indicate that a distorted pattern of renal calyces is an accurate predictor of high-grade VUR. Machine learning protocols can be enhanced in future to improve objective grading of VUR., Competing Interests: Conflict of interest The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Journal of Pediatric Urology Company.

Introduction: Severity of penile curvature (PC) is commonly used to select the optimal surgical intervention for hypospadias, either alone or in conjunction with other phenotypic characteristics. Despite this, current literature on the accuracy and precision of different PC measurement techniques in hypospadias patients remains limited., Purpose: Assess the feasibility and validity of an artificial intelligence (AI)-based model for automatic measurement of PC., Material and Methods: Seven 3D-printed penile models with variable degrees of ventral PC were used to evaluate and compare interobserver agreement in estimation of penile curvatures using various measurement techniques (including visual inspection, goniometer, manual estimation via a mobile application, and an AI-based angle estimation app. In addition, each participant was required to complete a questionnaire about their background and experience., Results: Thirty-five clinical practitioners participated in the study, including pediatric urologists, pediatric surgeons, and urologists. For each PC assessment method, time required, mean absolute error (MAE), and inter-rater agreement were assessed. For goniometer-based measurement, the lowest MAE achieved was derived from a model featuring 86° PC. When using either UVI (unaid visual inspection), mobile apps, or AI-based measurement, MAE was lowest when assessing a model with 88° PC, indicating that high-grade cases can be quantified more reliably. Indeed, MAE was highest when PC angle ranged between 40° and 58° for all the investigated measurement tools. In fact, among these methodologies, AI-based assessment achieved the lowest MAE and highest level of inter-class correlation, with an average measurement time of only 22 s., Conclusion: AI-based PC measurement models are more practical and consistent than the alternative curvature assessment tools already available. The AI method described in this study could help surgeons and hypospadiology researchers to measure PC more accurately., Competing Interests: Conflict of interest All co-authors have nothing to declare., (Copyright © 2023 Journal of Pediatric Urology Company.

The bladder exstrophy-epispadias complex includes some of the most challenging conditions treated by pediatric urologists. They are associated with the need for multiple intricate reconstructive procedures, aimed at restoring the anatomy and function of the bladder, urethra and external genitalia. These patients often endure multiple redo reconstructive procedures to improve urinary function, sexual function and cosmesis throughout the first two decades of life. In this article, we present the 30-year experience of a single surgeon performing redo surgery for males born with epispadias and bladder exstrophy. Through detailed documentation of 6 clinical cases, we highlight technical aspects that may contribute to a successful surgical reconstruction in these patients. The article is focused specifically on patients undergoing redo epispadias repair with or without concomitant continence procedures. We make the case for complete penile disassembly with external rotation of the corpora to correct recurrent dorsal curvature; this approach also allows the surgeon to have access to the proximal urethra and bladder neck after opening the intersymphiseal scar/band. This is useful when additional procedures on the bladder, such as bladder neck tailoring, are necessary. We also highlight the importance of avoiding reverse Byars' flaps when performing skin closure, due to the resulting midline scar. Besides being associated with a poor cosmetic outcome, it can also contribute to recurrent dorsal curvature. The authors advocate for rotational skin flaps to cover the penile shaft. Correction of dorsal curvature and improved cosmesis obtained with complete penile disassembly sometimes comes at the expense of the urethra being left as a hypospadias (figure). This will require further surgeries (usually a 2-stage buccal mucosa graft), much like the treatment of proximal hypospadias. Redo epispadias surgery in males remains a challenge. The systematic approach offered by the case scenarios may help guide surgeons dealing with this difficult condition. Patient with complications after repair of classic bladder exstrophy. A) Stone retrieved from posterior urethra after complete penile disassembly. B) After opening the inter-symphiseal scar, the bladder has been opened and the bladder neck tailored. C) Complete penile disassembly has been completed with corporal bodies and urethra individualized. D,E,F) Final appearance of the repair; abdominal wall was closed with anterior rectus sheath flaps, penile skin was closed with rotational flaps and urethra ended up as a hypospadias., Competing Interests: Conflict of interest None of the authors have conflicts of interest to disclose., (Copyright © 2024 Journal of Pediatric Urology Company.

Introduction: Historically, repair of bladder exstrophy (BE) is associated with compromise to the upper tracts; the single stage repair of BE was considered to exacerbate risks of kidney impairment., Objective: We aim to evaluate the risk of upper urinary tract deterioration or chronic kidney disease after the complete primary repair of exstrophy (CPRE)., Study Design: As part of the U.S.-India Multi-institutional Bladder Exstrophy Collaboration, we prospectively performed data collection on all patients managed at the Civil Hospital, Ahmedabad from 2010 to 2020. All patients who underwent primary or redo BE or primary penopubic epispadias (PE) repair using CPRE were included. Data on annual VCUG and DMSA, serum creatinine and cystatin-C, urinary albumin, and creatinine were aggregated., Results: 72/104 patients who underwent CPRE at a median age of 1.7 years (IQR: 1.1-4.6) were included: 43(60%) patients with primary BE, 17(24%) with redo BE, and 12(17%) with primary PE. At a median follow-up of 4 years (IQR: 3-6), the overall median eGFR was 105 for BE, and 128 ml/min for PE. 14(19%) patients had eGFR<90, and 22(31%) had microalbuminuria. 21(30%) patients had kidney scarring in DMSA and 31(44%) had VUR. Multivariate analysis showed that neither kidney scarring nor VUR could predict the presence of eGFR<90 or microalbuminuria. Of 72 patients, 2 (3%) patients had dry intervals >3 h, 9 (13%) patients have dry intervals of 1-3 h and 44 (61%) patients had dry intervals <1 h during follow-up. We found that kidney function outcomes (i.e., eGFR and microalbuminuria) were not associated with continence status (p = 0.3)., Discussion: In this series, we report a 5% incidence of CKD stage 2 or above that was not impacted by continence status. Furthermore, a 40% incidence of VUR and a 30% incidence of kidney scarring during follow-up was observed within this cohort, neither of which had a significant impact on renal function deterioration (i.e, decline in eGFR), but underscores the need for close kidney surveillance in children that have undergone bladder exstrophy repair., Conclusions: Modern CPRE technique for the repair of BE may increase the risk of kidney scarring in the intermediate-term follow-up, however, this finding does not correlate with low eGFR and presence of albuminuria inpatients. Therefore, close follow-up with serial kidney function measurements is warranted and necessary after CPRE., 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 © 2022.

Purpose: Compartment Syndrome (CS) has been recognized as a potential factor that worsens testicular viability after detorsion, especially in borderline cases of prolonged ischemia. Fasciotomy of the testicular tunica albuginea to relieve the pressure associated with CS has been proposed to accommodate edema after detorsion, embracing the raw fasciotomy area with tunica vaginalis flap (TVF) or graft. Fashioning the TVF can be tedious in cases of severe scrotal edema. Herein we present a technique that facilitates and expedites the procedure, maintaining the fasciotomy area decompressed., Materials and Methods: In testicular torsion, where the testis remains with dark coloration and questionable viability after detorsion a longitudinal releasing incision is made in the tunica albuginea (fasciotomy) to decrease compartmental pressure. If signs of parenchymal recovery (bleeding points, better color) are seen an orchio-septopexy is performed, suturing the incised albuginea's edges to the septum with a running suture, avoiding CS as well as re-torsion., Results: Orchio-septopexy was performed in 11 cases with a mean age of 11.9 years (3-17). All cases had clinic follow-up and testicular Doppler US with a mean of 9.5 months (6-24). 6/11 cases (54%) were salvaged, with good vascularity in the Doppler US and maintained more than 50% testicular volume compared to the contralateral side., Conclusion: Orchio-septopexy after testicular fasciotomy is a simple and fast technique that can be utilized in cases of prolonged testicular ischemia and questionable viability. More than half of the testes recovered, encouraging us to propose its utilization as well as its validation by other surgeons., Competing Interests: None declared., (Copyright® by the International Brazilian Journal of Urology.)

Introduction: Bladder exstrophy (BE) affects continence and sexual function, impacting on social life and mental health. Long-term data from the patients' point of view are needed to get a real-life perspective on the problem., Study Design: A self-developed questionnaire concerning sexual, psychosexual and psychosocial outcomes was sent to the adult members of the Brazilian Exstrophy Group., Results: Fifty out of 67 adults from the group (74.5%) responded to the questionnaire. Failure of initial bladder closure attained 62%. Almost ¾ of the patients had augmentation cystoplasty. Bladder lithiasis was common. Esthetic procedures were frequently done. Repetitive UTI (n = 32, 64%) and kidney scars/disease (n = 20, 40%) were frequent. Most (88%) patients either depend on CIC or remain incontinent. Sexual problems predominated in males. Surgery for continence often failed, requiring re-operations, but the prognosis without these procedures was comparatively worse. Continent patients underwent more surgeries (mean 18, 13 and 9 procedures in continent, imperfectly continent and incontinent patients, respectively). Augmented patients more frequently achieved dryness (p = 0.0035). Two-thirds of the women underwent vaginoplasties, but dyspareunia/feeling of "tight" vagina still affected a quarter of them. Four women (15.4%) delivered healthy children. 91.7% of the males reported "normal" erections, but sexual inhibition was common due to feeling of having a small penis (n = 18, 75%). Persistent dorsal curvature and abnormal ejaculation were common (58.3% and 77.1%, respectively). Patients' comments related mainly to mental health issues/need for specialized care, limitations of medicine to cure/treat their disease, unavailability of experts, especially adult specialists, embarrassment over deformities and insufficient information about disease/treatment/prognosis., Discussion: Most BE patients are well-integrated into society, but feelings of sadness and low self-esteem are common. Most welcome procedures to become dry, despite self-catheterization. The results of bladder neck reconstruction are far from perfect, despite multiple attempts and bladder augmentation was often necessary. Volitional voiding is uncommon. Sexual problems are worse for males, and sexual avoidance is common. Sexual function and self-image are inter-related. It seems reasonable to offer selective esthetic procedures to improve social/sexual interaction. Obstetric complications are common, especially UTI, need for ureteral and/or conduit stenting, abnormal fetal positioning, uterine prolapse, technical problems during surgical deliveries and prematurity., Conclusion: Continence/dryness in BE was mostly eventually achieved, usually depending on multiple interventions, bladder augmentation and self-catheterization. Despite multiple surgeries many adults remain incontinent. Sexual problems and avoidance are the rule in males, due to the feelings of penile inadequacy. Pregnant females deserve expert obstetric care., (Copyright © 2021 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.)
