Comparison of traditional enterocystoplasty and seromuscular colocystoplasty lined with urothelium.

OBJECTIVE

To evaluate long-term outcomes between various methods of augmentation cystoplasty.

METHODS

A retrospective analysis was performed of patients undergoing seromuscular colocystoplasty lined with urothelium (SCLU, n=26), and their outcomes compared to a similar population of patients in the same institution who had received traditional forms of bladder augmentation (colocystoplasty and ileocystoplasty, n=32). Measurements included efficacy of the procedure in increasing bladder capacity and achieving urinary continence, and the need of subsequent surgery for complications.

RESULTS

There was no statistically significant difference in achieved bladder capacity, subjective urinary continence and the rates of subsequent surgery for stones, vesicoureteral reflux, augment failure, bladder neck continence and catheterizable channel. None of the patients in the SCLU group had spontaneous perforation or small bowel obstruction.

CONCLUSION

Patients with SCLU are at decreased risk for bowel obstruction and spontaneous perforation, but are not devoid of other long-term complications including bladder stones, vesicoureteral reflux and augment failure. Most of the risks and benefits of augmentation cystoplasty performed using ileum, colon, or SCLU appear similar.
