Sigmoidocystoplasty after total cystectomy for bladder cancer: a follow-up study.

Data on 47 patients who underwent sigmoidocystoplasty after total cystectomy for bladder cancer from 1960 to 1979 are presented. The overall survival rates were 53.3 per cent at 5 years and 41.3 per cent at 10 years, respectively. The urethral recurrence of cancer occurred in 8 (17 per cent) patients with bladder neck or multiple cancers. Long-term follow-up studies revealed that hydronephrosis with vesico-ureteral reflux and mild acidosis occurred in some patients, but severe deterioration of renal function was nil. We emphasize that sigmoidocystoplasty should widely be considered for patients with extratrigonal bladder cancers infiltrating but not extending beyond the muscle layer.
