To determine the effectiveness of small intestinal submucosa(SIS) cystoplasty and to compare with augmentation using standard bowel.


A retrospective analysis was performed of patients undergoing small intestinal submucosa cystoplasty ( SIS, n=7), and their outcomes compared to a similar population of patients in the same institution who had received traditional augmentation colocystoplasty (CC, n=7). Measurements included efficacy of the procedure in increasing bladder capacity, achieving urinary continence, and the short-term and long-term complications.


Follow-up range was 2 to 8 years (mean 3 years). Compared to the preoperative examinations there were significant increases in maximum bladder capacity and bladder compliance at the follow up in both SIS and CC groups, and there was no statistically significant difference between the two groups. Bowel function returned more promptly after surgery in SIS group than CC group. Renal function was preserved in both groups. But the complications after CC surgery were more severe than SIS surgery, including bowl obstruction, UTI, acidosis and bladder rupture. There was no statistically significant difference in the rate of continence and CIC between the two groups.


SIS cystoplasty can provide a viable option for bladder reconstruction in patients with neurogenic bladder. Patients with SIS cystoplasty are at decreased risk of complications than enterocystoplasty.
