vesicosigmoidostomy
Pronunciation: VES-ih-koh-sig-moy-DOS-toh-mee
Surgical connection of the bladder to the sigmoid colon for urinary diversion, now largely historical.
Full Definition
Vesicosigmoidostomy is a urinary diversion procedure that creates a direct anastomosis between the bladder and sigmoid colon, allowing urine to drain through the rectum and be expelled with bowel movements. This technique was historically used for patients requiring cystectomy but has largely been abandoned due to significant complications including electrolyte imbalances, recurrent urinary tract infections, and increased risk of malignancy at the anastomotic site. Modern urological practice favors alternative diversions such as ileal conduits or continent pouches. Understanding this procedure remains important for urologists managing patients with historical diversions or considering revision surgeries.
Usage
Usage note: Largely historical procedure; emphasize modern alternatives when discussing.
