Functional, augmented rectal bladder: early clinical experience.

From August 1988 until March 1990, 10 female patients received an augmented, functional rectal bladder according to the technique first described by Kock. Indications were radical cystectomy in 8 and undiversion from a previously wet stoma in 2 patients. There was no perioperative mortality. Postoperative complications were: one obstructive pyelonephritis (treated with a temporary nephrostomy); one obstruction at the ileal intussusception (operative revision), and one slipping at the sigma nippel (no treatment). Intravenous pyelographies taken 2-3 months postoperatively, showed 13 normal and 5 slightly dilated renal units. All patients are completely continent by day, 7 are continent at night, 2 wear sanitary pads during the night due to occasional spotting. The preliminary experience with this new technique is encouraging and warrants further clinical application in patients in whom the external urethral sphincter is not available as continence organ.

[The functional, augmented rectal bladder. Initial clinical experience with 10 patients].

From August 1988 until March 1990, 10 female patients received an augmented, functional rectal bladder, according to the technique first described by Kock. Indications were a radical cystectomy in 8 and a rediversion from a previously wet stoma in 2 patients. There was no perioperative mortality. Postoperative complications were obstructive pyelonephritis (1 case, treated with a temporary nephrostomy), obstruction at the ileal intussusception (1 case; operative revision) and slipping at the sigmoid nipple (1; no treatment). Intravenous pyelography 2-3 months postoperatively showed 13 normal and 5 slightly dilated renal units. All patients are completely continent by day, 7 are continent by night, 2 wear sanitary pads during sleep due to occasional spotting. Preliminary experience with this new technique is encouraging and warrants further clinical application in patients in whom the external urethral sphincter is not available to provide the continence mechanism.

The functional rectal bladder--prevention of hyperchloremic acidosis following vesico-sigmoidostomy in dogs.

Urinary diversion by a vesico-sigmoidostomy was performed in fourteen dogs. The animals were randomly divided into two groups. Group 1 had an isoperistaltic intussusception of the sigma proximal to the vesico-sigmoidostomy. Group 2 was used as control without intussusception. In the postoperative course, serum creatinine, chloride, pH, bicarbonate, base-excess were controlled over a period of four months twice weekly. Additionally, IVPs were taken in all dogs and rectograms performed in the intussuscepted group. While IVPs and creatinine values demonstrated normal postoperative kidney function in all dogs of both groups, acidbase parameters including chloride were significantly (p less than 0.001, Wilcoxon test) better in group 1. Intussusception of the sigmoid colon is a reliable operative way to significantly reduce hyperchloremic acidosis in the course of urinary diversion into the sigmoid colon, while the fecal stream remains undisturbed.
