Modified staged repair of bladder exstrophy: a strategy to prevent penile ischemia while maintaining advantage of the complete primary repair of bladder exstrophy

Long-term psychosexual adjustment of adults born with classic bladder exstrophy

BACKGROUND

In literature studies exploring long-term psychosexual development and intimacy of adults living with the complex genitourinary conditions associated with classic bladder exstrophy (BE) are scarce, with small sample sizes and lacking in methodology.

OBJECTIVE

This study aims to examine areas of potential psychosexual distress in adults born with classic BE to develop targeted clinical interventions.

STUDY DESIGN

The validated Sexrelation Evaluation Schedule Assessment Monitoring (SESAMO) questionnaire was administered to all BE patients aged ≥18 years operated on in our tertiary referral center during infancy. Z-scores were calculated for each area of interest, considering i) gender (female vs male); ii) committed partnership status (singles vs couples); iii) the voiding technique adopted to empty the bladder.

RESULTS

A total of 33 (F:M 12:21; singles: couples 11:22) adults with BE were enrolled in the study at a median age of 39 (32-47) years. Overall, BE adults performed the worst regarding psychosexual identity (z-score:-1.282), pleasure (z-score:-0.915) and desire (z-score:-0.583); singles regarding relational attitude (z-score:-1.751) and imaginative eroticism (z-score:-0.806); couples regarding extramarital sexuality (z-score:-1.175) and sexual communication (z-score:-0.255). When it came to gender, females significantly performed worse than males regarding psychosexual identity (-1.645 vs -1.282; p-value:<0.0001) and areas of pleasure (-1.126 vs -0.359; p-value:<0.001). Single females performed worse than males regarding actual masturbation (-0.763 vs 0.583; p-value:<0.05) and better regarding relational attitude (-1.226 vs -1.751; p-value:<0.05). Females in stable relationships performed worse than males regarding actual masturbation (-1.645 vs 0.306; p-value:<0.05) and better regarding sexual intercourse (1.866 vs -0.565; p-value:<0.01). The voiding techniques used to empty the bladder did not show any influence on these results.

CONCLUSION

Adults with BE have a greater likelihood of experiencing a wide range of psychosexual difficulties. Identifying the specific areas of psychological distress can help them cope with their medical experience and actual clinical condition and clinicians plan adequate psychological interventions.

Achieving goal capacity for continence surgery: A cumulative event analysis of bladder exstrophy patients

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.

Indocyanine Green (ICG)-Guided One-Stage Delayed Bladder Closure and Radical Soft-Tissue Mobilization (Kelly Procedure) For Bladder Exstrophy Repair: The First Experience

The vascular supply of the pelvic structures and the external genitalia can be easily injured during the one-stage delayed bladder closure and radical soft-tissue mobilization (Kelly procedure) for bladder exstrophy surgical repair. Aiming to help surgeons assessing and confirming tissue perfusion and viability, indocyanine green (ICG)-based laser angiography was incorporated into the operative approach to reduce the risk of ischemic injuries. The EleVision IR system (Medtronic Ltd) was adopted to confirm the identification of the vascular pedicles and assess the tissue perfusion in real-time in a 5-month-old with bladder exstrophy undergoing the one-stage delayed bladder closure and radical soft-tissue mobilization (Kelly procedure). ICG (0.15 mg/kg) was intravenously administered at 6 key steps during surgery with the ability to be re-dosed every 15 minutes. ICG-based laser angiography helped to confirm the correct identification of the vascular structures during surgery and to assess tissue perfusion in real-time. Blood flow did not change considerably after initial dissection or upon approximating the pubis symphysis. At the end of the procedure, good penile perfusion was shown, proving that no direct injury or substantial compression of the pudendal vessels had occurred following the mobilization and the reconstructive phase. ICG-based laser angiography proved to be safe, effective, and easy to employ and should be considered as a reasonable adjunct for tissue perfusion assessment and operative decision-making in patients undergoing bladder exstrophy Kelly repair.

Kidney function outcomes in patients after complete primary repair of bladder exstrophy and penopubic epispadias: Results from the international bladder exstrophy consortium

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.

Intraoperative laser angiography in bladder exstrophy closure: A simple technique to monitor penile perfusion

BACKGROUND

The successful repair of Bladder Exstrophy remains one of the biggest challenges in Pediatric Urology. The primary focus has long been on the achievement of urinary continence. Historically there has been less focus on early penile outcomes. To this end we have incorporated penile perfusion testing using intraoperative laser angiography in to our operative approach.

OBJECTIVE

We hypothesize that assessment of penile perfusion at various points in the procedure is a feasible technique that may assist in decision making during the repair of this complex condition. This will reduce the risk of tissue compression and potential loss of penile tissue that has been reported to occur as a complication of the procedure.

STUDY DESIGN

Consecutive patients presenting with bladder exstrophy were evaluated at four stages of their operation (i.e. following induction of anesthesia, after bladder mobilization, following internal rotation of the pubis and at the end of the procedure) by infusing indocyanine green (ICG) at a dose of 1 mg per 10 kg body weight. Measurements were taken at 80 s post infusion and the medial thigh served as the reference control. Postoperative penile viability was evaluated by visual inspection and palpation three months following the procedure.

RESULTS

Eight consecutive patients were included in this study. Perfusion was easy to measure and posed no significant technical difficulties. Penile perfusion increased slightly following bladder dissection. Internal rotation of the hips with apposition of the symphysis pubis resulted in an average 50% reduction in penile blood flow. Patients undergoing CPRE experienced an additional mean 33% drop in blood flow. In all eight cases the penis was symmetric and healthy with no sign of tissue loss at three months follow up.

CONCLUSIONS

This pilot study demonstrates that the measurement of penile perfusion utilizing intraoperative laser angiography is easy to employ and should be considered a reasonable adjunct to tissue assessment in this complex condition. Marked reduction in penile blood flow may occur without any outward clinical signs. Penile perfusion is markedly reduced by apposition of the symphysis pubis and, in the immediate postoperative period, there may be further reduction in penile blood flow with CPRE as opposed to a staged repair. Future correlation with measures of penile viability and function are needed to define the clinical utility of this modality.

Bladder exstrophy: We need to improve. A lot

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.

Penile Disassembly in Complete Primary Repair of Bladder Exstrophy: Time for Re-evaluation?

OBJECTIVE

To explore a series of classic bladder exstrophy (CBE) cases referred to the authors' institution where primary closure with penile disassembly epispadias repair was complicated by penile injury. The penile disassembly technique is frequently combined with bladder closure in patients with CBE undergoing the complete primary repair of exstrophy (CPRE). Penile disassembly has been posited as a risk for penile injury by ischemic mechanisms.

METHODS

A prospectively-maintained institutional database of 1337 exstrophy-epispadias complex patients was reviewed for CPRE cases referred to the authors' institution, and those with injury to the penis were identified. The location, extent of injury, and subsequent management is reported.

RESULTS

One hundred and thirteen male CBE patients were referred after prior CPRE. Twenty-six (20%) were identified with penile loss and reviewed. Eighty-one percent were closed in the neonatal period, and 54% had a pelvic osteotomy. Median follow-up time was 9.9 years (range 0.6-21.3). Of 26 patients with penile loss, 77% had unilateral loss and in 23% had bilateral loss involving the glans and/or one or both corpora cavernosa. Three patients were successfully managed with myocutaneous neophalloplasty.

CONCLUSION

Complete penile disassembly during bladder exstrophy closure may lead to penile injury. This major complication questions the continued application of complete penile disassembly in the reconstruction of bladder exstrophy.

A less invasive technique for delayed bladder exstrophy closure without fascia closure and immobilisation: can the need for prolonged anaesthesia be avoided?

INTRODUCTION

It is believed that the main factors enhancing security of the bladder exstrophy closure are use of osteotomy, pubic bones approximation or transferred flaps for rectus fascia closure. However, these methods increase operating time, surgical trauma and carry risks for the patient.

OBJECTIVES

To demonstrate that the goal of secure bladder exstrophy closure can be achieved easier technically and safer for the child than previously thought. The paper examines the hypothesis that less invasive bladder exstrophy closure achieved without fascia closure can reduce pain and avoid the need for immobilization and prolonged analgesia.

STUDY DESIGN

Patients aged 34 days to 15 years (n = 36) from 37 who consecutively referred to the institution with classical bladder exstrophy between 2004 and 2016 underwent modified delayed primary (25) or redo (11) closure. One boy with low weight was excluded. Patient and treatment features were analysed to determine needs for immobilisation and anaesthesia in the postoperative period, and outcomes.

PROCEDURE

Bladder exstrophy closure with proximal urethroplasty was performed with the detachment of crura from the ishiopubic rami and levators-from obturator internus muscle. Abdominal wall closure was accomplished with skin and subcutaneous fat mobilisation without rectus fascia closure. No method of immobilization was applied.

RESULTS AND LIMITATIONS

Bladder closures have been successful in all 36 children in this report after 37 months (22-138) follow up. The surgeries took time between 126 and 215 min (mean - 148). After 1 day in the ICU the majority of the patients (34/36) were returned to the ward. No bladder spasms or signs of acute pain were noted in the ward; therefore, no local anesthesia or opioids were needed. Intravenous analgesia with non-narcotic analgesics was used for all patients in the ward for an average period 2.2 days (95% CI 2-4 days).

COMPLICATIONS

Minor complications: two fistulas, which closed spontaneously; three bladder outlet obstructions, each required one endoscopic incision. No major complications of exstrophy closure such as dehiscence or bladder prolapse were occurred.

CONCLUSIONS

The proposed less invasive technique with relieved postoperative program is the way to obtain successful bladder exstrophy closure as well as to reduce some risks for the patients. Absence of major complications, and avoiding the need for immobilisation and prolonged analgesia, contribute to the benefits of this approach.
