Reduction cystoplasty in prune belly syndrome.

Reduction cystoplasty is a useful procedure to treat a large, poorly functioning bladder in boys with prune belly syndrome who are candidates for urinary tract reconstruction. The technique includes elliptical resection of all anomalous urachal tissue and sufficient detrusor dome to reduce bladder capacity to average size and to create a spherical detrusor. Improved detrusor function and a satisfactory or excellent result can be expected.
