The study aimed to assess the long-term kidney function outcomes in patients who underwent ureteroureterostomy (UU) after surgery for non-urothelial cancers, and to determine the maximum length of ureter defect that can be bridged successfully with UU.
A retrospective review of 19 patients showed that UU had a high success rate, with only one patient experiencing significant kidney function decline due to UU failure, while others faced issues linked to cancer recurrence.
Overall, UU effectively maintained long-term renal function in most patients, especially when the ureteric defect was 5 cm or less.
