Ureterocalycostomy is a surgical procedure that involves creating an anastomosis, or connection, between the ureter and the renal calyx. This procedure is specifically indicated for cases where the renal pelvis is severely fibrosed or scarred, making traditional ureteropyelostomy unsuitable. In ureteropyelostomy, the upper part of the ureter is joined to the lower part of the renal pelvis, while ureterocalycostomy connects the ureter to the calyces, which are the cup-like structures in the kidney that collect urine. This connection is typically performed to address conditions such as ureteropelvic junction (UPJ) obstruction or a long proximal ureteral stricture, which can impede the normal flow of urine from the kidney to the bladder. The procedure involves careful dissection and mobilization of the ureter, ensuring that the surrounding periureteral tissue is preserved to maintain blood supply and function. The ureter is then divided just below the narrowed area, and the proximal stump is ligated. The kidney is also mobilized, and any diseased or fibrotic tissue is excised to facilitate a healthy connection. A stent is placed to support the anastomosis during healing, ensuring that urine can flow freely from the kidney through the newly created connection.
