Insights
Urinary diversion in early childhood for classic bladder exstrophy (CBE) is safe and effective. Both continent and incontinent urinary diversion (CUD and IUD) can lead to favorable continence outcomes, with CUD showing better initial success rates.
Area of Science:
- Pediatric Urology
- Surgical Reconstruction
- Bladder Exstrophy Management
Background:
- Classic bladder exstrophy (CBE) often requires complex surgical management.
- Early childhood urinary diversion is sometimes necessary for patients with CBE.
- Continent and incontinent urinary diversion (CUD and IUD) are surgical options.
Purpose of the Study:
- To evaluate the indications for and applicability of CUD and IUD.
- To assess outcomes in early childhood patients with CBE undergoing urinary diversion.
- To determine the safety and efficacy of these procedures in young children.
Main Methods:
- Retrospective review of a CBE database for patients undergoing CUD or IUD within the first five years of life.
- Analysis of surgical indications, procedures performed, and clinical outcomes.
- Study included patients born after 1980 treated by two surgeons.
Main Results:
- In the CUD group (n=14), 21% had successful primary closure; indications included desire for dryness and upper tract changes. All patients achieved dryness with clean intermittent catheterization (CIC).
- In the IUD group (n=5), only one had successful primary closure; indications included severe hydronephrosis and recurrent UTIs. Four were later re-diverted to CUD. All achieved social dryness via catheterization.
- No cases of renal function loss or malignant transformation were observed in either group.
Conclusions:
- Early urinary diversion in CBE is often necessitated by upper tract deterioration and social factors.
- Both CUD and IUD can achieve favorable continence outcomes in young children with CBE.
- Urinary diversion is a safe and effective option for managing complex bladder exstrophy cases in early childhood.
Objective:
To evaluate indications and applicability of continent and incontinent urinary diversion (CUD and IUD, respectively) in early childhood in patients with classic bladder exstrophy (CBE).
Methods:
Using an institutionally approved exstrophy database, patients with CBE born after 1980 who underwent CUD or IUD by 2 surgeons within the first 5 years of life were identified. All aspects of their care and clinical outcomes were studied.
Results:
In the CUD group (n = 14), only 21% had successful primary closure. Indications were desire to be dry (7), persistent hydronephrosis (4), urinary tract infections (UTIs) (1), repeat CUD (1), and inaccessible proper follow-up (1). Three patients had neobladder creation, 10 had bladder augmentation with continent stomas, and 2 underwent ureterosigmoidostomy. Currently, all patients are dry with clean intermittent catheterization (CIC). In the IUD group (n = 5), only 1 had successful primary closure. In addition to small, noncontractile bladders, the indications for IUD were severe hydronephrosis (2), recurrent UTIs (2), and noncompliance with catheterization (1). Four patients were re-diverted to CUD after a mean of 9.4 years and 1 has colon conduit. All are socially dry via catheterization. There was no case of renal function loss or malignant transformation.
Conclusion:
The need for early diversion in CBE is primarily driven by upper tract changes after secondary closure and social factors. Urinary diversion can be safe in younger children with a favorable continence outcome.
