Management of Untreated Classical Bladder Exstrophy in Adults: A Single-Institutional Experience

Abstract

To report our single center experience in the management of untreated adult classical bladder exstrophy. A retrospective review of 25 adults aged ≥18 years who underwent repair of the classical bladder exstrophy from April 2000 to February 2020 was performed. Patients with prior repair and neoplastic changes in the exposed bladder mucosa were excluded. The patients and primary caretakers were actively involved in the decision-making of the surgical procedures best suited them. Work-up included upper tract evaluation and random bladder mucosal biopsy. The mean age of presentation was 25 years. Primary schooling was completed by only 32% patients. The majority (72%) of the patients opted continent catheterizable pouch. Penn pouch was the most common pouch performed. In 3 patients, a complete primary repair was done in a single setting. In 4 patients with lack of education and difficult access to nearby health care settings, ileal conduit was performed. In all except 3 (13.1%), abdominal wall closed primarily. None of the patients required osteotomy. At a mean follow-up of 6.5 years, all patients with continent pouches were continent. One patient required revision of left ureteroneocystostomy at 20 months follow-up. All except one patient, who had complete primary repair were continent at a mean follow-up of 6 years. Management of adult classical bladder exstrophy is challenging. The various pouches extend the surgical options. Ileal conduit may be a simple alternative to complex reconstructions in unmotivated patients with poor access to the hospital.
