Abstract

INTRODUCTION: Bladder exstrophy remains one of the most challenging abnormalities in pediatric urology. We propose bladder neck transection and bladder augmentation with a catheterizeable reservoir technique to achieve continence after previous anatomic reconstruction in stages.

METHODS: At the age of 5-6 years, we offer the transection of bladder neck and enterocystoplasty to achieve continence. We report on a 6-year-old boy that underwent this procedure. We perform the reservoir from ileum according to Macedo-technique that constructs a catheterizeable channel from the same bowel segment. The continence mechanism of the efferent tube is based on angulation and a serous lined tunnel created with 3.0 prolene sutures. The stoma is placed in the midline.

RESULTS: Patient had an uneventful evolution and is continent performing CIC every 4 h with 9 months of follow up.

DISCUSSION: In spite of continuous development of bladder exstrophy surgery, the urethral continence and voluntary micturition is still not possible in the majority of patients. We discuss with our patients honestly and offer this method as a viable alternative to achieve continence.

CONCLUSION: In our experience, most patients accept urethral transection and suprapubic CIC when educated about results with other alternatives of bladder neck plasty.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
