[Continent urostomy: sigmoid reservoir and sigmoid hydraulic valve]

Abstract

We report our experience of continent sigmoidostomy. The technique consisted in urinary diversion with sigmoid pouch and hydraulic valve. Eleven patients underwent this procedure (10 men and 1 women, mean age 48 years, range 20 to 77 years). Indications were bladder tumor in 7 cases, bladder exstrophy in 2 patients, neurogenic bladder in 1 case and 1 bladder with a small capacity secondary to a stricture of traumatic urethra. The pouch was made according to the detubularized model. The sigmoid was opened on its antimesenteric edge, leaving the distal portion of the sigmoid intended to do the sigmoid valve. The posterior edges of the colonic segment opened were alined then secured by a Dexon 3/0 whipping then the anterior adges were secured, as the former after reimplantation of the ureters according to Camey Leduc or Politano Leadbetter's procedure. The post operative follow-up was marked by a fistula of the pouch in one case treated by securing it. All the patients were continent day and night. The purpose of this study was the description of the technique and the results of the continent sigmoïdostomy.
