Sigmoidocystoplasty to augment bladder capacity.

Sigmoidocystoplasty with subtotal cystectomy was carried out in 14 patients with severe, symptomatic contracture of the bladder, refractory to other modes of therapy. Eight patients had excellent results, four showed improvement, two showed no improvement and required supravesical diversion. Indications for the procedures, complications and over-all results are discussed, with emphasis on our surgical technique. The possible advantages of sigmoidocystoplasty over ileal and ileocecal cystoplasty are noted.
