Enterocystoplasty or detrusor myectomy? Comparison of indications and outcomes for bladder augmentation

Purpose: We review our experience with enterocystoplasty and detrusor myectomy to delineate clinical indications and compare operative outcomes with both types of bladder augmentation. Materials and Methods: Retrospective analysis of 61 patients who had undergone a total of 37 detrusor myectomies and 32 enterocystoplasties was performed. The patients were categorized into 6 diagnostic subsets representative of the clinical spectrum of indications for bladder augmentation. Results: For most clinical indications detrusor myectomy offered comparable success or significant improvement in bladder function without incurring the significant complication rate of enterocystoplasty. Conclusions: Detrusor myectomy is a safe, successful method of bladder augmentation for most clinical indications. Myectomy does not hinder subsequent creation of an enterocystoplasty.
