Ureteral tissue expansion for bladder augmentation

The Journal of Urology

Abstract

Ureteral augmentation is an effective method of bladder reconstruction using the native urothelium of a megaureter. Clinically this procedure is contingent on the presence of an enlarged ureter. We have iatrogenically produced a segmental megaureter, while preserving renal function in a pig model. The urothelium of the enlarged ureter was then used for augmentation cystoplasty. A tissue expander suitable for insertion into the lumen of the ureter was constructed. The tissue expander was passed antegrade through a flank incision of 8 pigs, and a separate nephrostomy tube was left in place. During the ensuing 1 to 4 weeks the pigs underwent daily dilation of the tissue expander without anesthesia. After dilation the pigs underwent ureteral augmentation of the bladder. The segment of expanded ureter was isolated from the native ureter, opened and anastomosed to the bladder. The continuity of the left ureter was restored by primary ureteroureterostomy. The animals underwent cystograms at 1 and 4 weeks and were sacrificed 4 weeks after augmentation. Tissue was harvested for gross and microscopic histology. Of the 8 pigs starting the protocol 5 underwent successful ureteral tissue expansion followed by bladder augmentation. Tissue ex...Continue Reading
