ureterostomy
Pronunciation: you-REE-ter-AH-stoh-mee
Surgical creation of an opening between the ureter and skin surface to allow urine drainage when normal bladder function is not possible.
Full Definition
A urinary diversionary procedure involving the surgical creation of a stoma by bringing the ureter to the skin surface, allowing urine to drain directly from the kidney without passing through the bladder. This procedure may be performed as a temporary measure during complex reconstructions or as permanent diversion in cases of bladder dysfunction, malignancy, or congenital anomalies. Types include cutaneous ureterostomy, end ureterostomy, and loop ureterostomy. The procedure requires careful surgical technique to prevent stricture formation and ensure adequate drainage while maintaining ureteral vascularity.
Usage
Usage note: Specify type (cutaneous, end, loop) and indication; distinguish from other urinary diversions.
