RESUMO

PURPOSE: The risk factors for future infertility in adolescents with varicocele are controversial, and little is known about the association between hormone levels and semen parameters. Semen analysis is likely the closest marker of fertility but may be difficult to obtain in some boys secondary to personal, familial or religious reasons. Identifying other clinical surrogates for abnormal semen parameters may offer an alternative for assessing varicocele severity in these boys. We hypothesized that hormone levels and total testicular volume are predictive of abnormal total motile sperm count. MATERIALS AND METHODS: We retrospectively reviewed Tanner 5 boys with palpable left varicoceles who underwent a semen analysis and had serum hormone levels tested (luteinizing hormone, follicle-stimulating hormone, inhibin B, anti-müllerian hormone and/or total testosterone) within a 6-month period. Total testicular volume was also calculated. Abnormal total motile sperm count was defined as <9 million sperm per ejaculate. RESULTS: A total of 78 boys (median age 17.2 years, IQR 16.5-18.0) were included. Luteinizing hormone, anti-müllerian hormone and total testosterone were not correlated with any semen analysis parameter. There was a negative correlation between follicle-stimulating hormone and total motile sperm count (ρ -0.35, p=0.004) and positive correlation between inhibin B and total motile sperm count (ρ 0.50, p <0.001). Total testicular volume was significantly positively correlated with total motile sperm count (ρ 0.35, p=0.01). ROC analyses revealed an optimal follicle-stimulating hormone cutoff of 2.9, an optimal inhibin B cutoff of 204 and an optimal total testicular volume cutoff of 34.4 cc to predict abnormal total motile sperm count. CONCLUSIONS: Total motile sperm count is inversely associated with follicle-stimulating hormone levels, and directly associated with inhibin B levels and total testicular volume. Optimized cutoffs for serum follicle-stimulating hormone, inhibin B and total testicular volume may prove to be reasonable surrogates for total motile sperm count in boys who defer semen analysis for personal or religious/cultural reasons.

RESUMO

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.

RESUMO

Introduction: Caring for children with bladder exstrophy-epispadias complex (BEEC) exacts a long-term emotional toll on caregivers. Previous studies leave a gap in understanding the impact that caring for a child with BEEC has on caregivers in low- and middle-income countries (LMIC). We hypothesize that families and caregivers experience psychological distress that has long gone unaddressed. Materials and methods: From 2018 to 2020, researchers conducted a multi-method evaluation of caregiver distress with participants recruited as part of the annual International Bladder Exstrophy Collaboration based in Ahmedabad, Gujarat, India. In 2018, pilot data was collected through cognitive interviews. In 2019, researchers conducted structured interviews predicated on themes from the previous year, which subsequently prompted formal mental health screenings in 2020. Caregivers who reported suicidal thoughts were immediately referred for intervention. Results: In 2018, caregivers described the primary source of stigma arose from their village (n = 9, 26.5%). Caregivers also identified long-term concerns (n = 18, 52.9%), including future fertility and marital prospects, as sources of anxiety. In 2019, caregivers substantiated preliminary findings with the primary source of anticipated (n = 9, 31%) and experienced (n = 19, 65.5%) stigma again stemming from their communities. Both cohorts identified the collaboration as a positive source of support (n = 23, 36.5%). In 2020, caregivers stated decreased emotional wellbeing as number of subsequent repairs increased (n = 54, 75%, p = 0.002). Caregivers of children who underwent initial surgery within 5 years of screening reported higher anxiety (n = 46, 63.8%) and this was exacerbated as the number of subsequent repairs increased (p = 0.043). Conclusion: Complex, long-term course of care, including additional surgeries, significantly impacts caregiver distress in the LMIC setting. Screening for caregivers of children with complex congenital anomalies, like BEEC, should be an essential element of any comprehensive effort to alleviate the global burden of disease.

RESUMO

Variants of bladder exstrophy are a rare but diverse spectrum of bladder exstrophy-epispadias complex. This case series describes a group of 4 unique exstrophy variant cases who had an intact phallus, but a completely open bladder plate. These patients underwent exstrophy repair and concomitant umbilicoplasty at the Civil Hospital, Ahmedabad as part of the US-India Multi-institutional Bladder Exstrophy Collaboration and were followed at the same institution. We believe that a detailed assessment of bladder neck prior to reconstructive repair and bladder closure would be beneficial in these cases as the extent of bladder neck involvement would affect reconstructive approach.

RESUMO

INTRODUCTION: Early proactive treatment of patients with high-risk neurogenic bladder from spina bifida (SB) may preserve renal function and decrease the need for bladder augmentation later in life. Timing of initiation of anticholinergic therapy (AC) medication and clean intermittent catheterization (CIC) is variable and based on imprecise studies. The authors hypothesized that initiation of AC after the initial video-urodynamic study (VUDS) may benefit bladder capacity even in children who do not meet the standard hostile criteria for starting AC. STUDY DESIGN: A retrospective review of a prospectively maintained VUDS database from August 2015 to March 2019 was performed. Patients with SB who had undergone initial VUDS between 1 and 7 months of age and had a subsequent follow-up study between 9 and 18 months of age were included. Multiple VUDS and clinical parameters including expected bladder capacity, actual capacity reached, pressure at actual capacity, presence of detrusor overactivity, presence of urinary tract dilation and reflux, and whether or not AC was started were extracted and compared. P-value of <0.05 was considered statistically significant. RESULTS: A total of 69 patients completed an initial study at median age of 2 months, and follow-up study at median age of 13 months. Anticholinergic therapy was started in 21 patients (10 F, 11 M). Decision to initiate AC was at discretion of the attending pediatric urologist performing the VUDS in real time. Changes between the initial and repeat VUDS are listed in the summary table below. Adverse effects of AC were reported in 25% (5/21) patients: urinary retention/UTIs (3), allergic reaction (1), and fatigue (1). DISCUSSION: The authors findings suggest that AC stabilizes storage pressure for those who initially have a higher storage pressure, while in those with initial low storage pressures, storage pressures worsened over time in the absence of AC. Patients started on AC experienced a faster rate of increase in bladder capacity. Limitations to this study included the unknown long term and sustainability of the improvement in bladder parameters, the lack of uniform criteria for the initiation of AC or CIC, and an unknown long-term degree of upper tract protection. CONCLUSION: This study found early initiation of AC in SB at 2 months of age had significant positive effects on growth of bladder capacity and stabilization of storage pressure. However, long-term effects of AC are still undetermined, and thus, longitudinal studies are needed to understand the precise indications for initiation of early AC treatment.

RESUMO

PURPOSE: The Multi-Institutional Bladder Exstrophy Consortium (MIBEC) was established in 2013 to refine technical aspects of the complete primary repair of bladder exstrophy (CPRE), to decrease complications, and to improve outcomes. In order to place outcomes from the consortium into context of historic outcomes, we evaluated continence and dry intervals in children who were repaired prior to the beginning of the consortium at these institutions. We hypothesized that continence (voiding with dryness) is rarely achieved after primary CPRE and surgery following CPRE improves dryness but may hinder voiding per urethra. MATERIALS AND METHODS: We reviewed prospectively maintained IRB approved databases of children who underwent CPRE for classic bladder exstrophy (BE) between 5/1993 and 1/2013 at 3 institutions. Exclusion criteria included: lack of continence documentation, and lack of follow up subsequent to January 2014. We recorded age at closure, method of bladder emptying, bladder capacity and surgical history. We used a 3 part dryness scale for both patients who void volitionally and those on CIC. Children were considered dry if they could hold urine for over 3 h. An intermediate group was defined as having a dry interval of 2-3 h, with minimal dampness in between voids. If dry intervals were <2 h with frequent leakage, children were considered wet. RESULTS: A total of 54 of 73 (38 M) children met inclusion criteria. 35 of 54 (64.8%) children void per urethra, while 18 (33.3%) perform clean intermittent catheterization (CIC) and 1 underwent a vesicostomy due to incomplete emptying and UTI's. 25/35 (71.4%) of those voiding per urethra underwent CPRE only, while the remaining 10 underwent secondary continence procedures. In total, 26 of 54 (48.1%) are dry, that is either continent or not wet for > 3 h, while only 11/54 (20.4%) are truly continent, i.e., voiding per urethra. Only 9/54 (16.7%) are continent after a single surgery (CPRE). 14/54 children who are dry (25.9%) underwent a bladder neck procedure with or without augmentation and empty with CIC. DISCUSSION AND CONCLUSION: Granular detail about the specifics of emptying, surgical history, and dry intervals is crucial to understand the true outcomes from the repair of BE. Children with BE undergoing CPRE prior to the institution of MIBEC experienced variable results, with only 17% achieving continence while spontaneously voiding per urethra without additional reconstruction. We are now engaged in MIBEC to identify factors that contribute to continence and to attempt to render such findings reproducible.

RESUMO

Importance: International collaboration to alleviate the massive burden of surgical disease is recognized by World Health Organization as an urgent need, yet the surgical mission model to treat reconstructive surgical challenges is often constrained in ensuring adequate patient follow-up, optimal outcomes, and sustainability. Objective: To determine whether a collaboration predicated on long-term commitment by surgeons returning to the same institution annually combined with an experienced host surgical team and infrastructure to ensure sustained patient follow-up could provide surgical care with acceptable outcomes to treat bladder exstrophy-epispadias complex (BE) and penopubic epispadias (PE). Design, Setting, and Participants: In this prospective, observational study, long-term collaboration was created and based at a public hospital in Ahmedabad, India, between January 2009 and January 2015. The entire postoperative cohort was recalled in January 2016 for comprehensive examination, measurement of continence outcomes, and assessment of surgical complications. Seventy-six percent of patients (n = 57) who underwent complete primary repair of exstrophy during the study interval returned for annual follow-up in 2016 and formed the study cohort: 23 patients with primary BE, 19 patients with redo BE, and 11 patients with PE repair. Main Outcomes and Measures: Demographics, operative techniques, and perioperative complications were recorded. A postoperative protocol outlining procedures to ensure monitoring of study participants was followed including removal of ureteral stents, urethral catheter, external fixators, imaging, and patient discharge. Results: Of the 57 patients, 4 were excluded because they underwent ureterosigmoidostomy. Median age at time of surgery was 3 years (primary BE), 7 years (redo BE), and 10 years (PE), with median follow-up of 3 years, 5 years and 3 years, respectively; boys made up more than 70% of each cohort (n = 17 for primary BE, n = 15 for redo BE, and n = 9 for PE). All BE and 3 PE repairs (27%) were completed with concurrent anterior pubic osteotomies. Seventeen of 53 patients (32%) experienced complications. Only 1 patient with BE (4%) had a bladder dehiscence and was repaired the following year. Conclusions and Relevance: A unique surgical mission model consisting of an international collaborative focused on treating the complex diagnoses of BE and PE offers outcomes comparable with those in high-income countries, demonstrating a significant patient retention rate and an opportunity to rigorously study outcomes over an accelerated interval owing to the high burden of disease in India. Postoperative care following a systematized algorithm and rigorous follow-up is mandatory to ensure safety and optimal outcomes.
