Cutaneous loop versus Roux-en-Y ureterostomy: a comparison of two methods for diversion of urine.
Loop and Roux-en-Y ureterostomies are compared. Both methods have a place if diversion is necessary in cases of severe hydronephrosis and decompensated ureters. Although the loop ureterostomy has advantages, it can lead to problems, i.e., the nonfunctioning and the contracted bladder. This serious complication is not seen after Roux-en-Y ureterostomy, because the bladder continues to function. The localization of the new pyeloureteral junction is discussed as the formation of kinks in this region must be avoided.
