The objective of this study was to evaluate failure rate after ureteroneocystostomy for malignant ureteral obstruction and to elucidate any predictive pre-operative factors leading to these failures. Failure was defined as requiring a new stent or percutaneous nephrostomy tube within thirty days of surgery.
From 2003-2015, there were 257 patients who underwent ureteroneocystostomy with 27 failures for a stricture rate of 9.5%. The one and five year risk of failure were 7% and 22%, respectively. Only salvage or palliative radiation were associated with the development of an anastomitic failure. The majority of patients who had undergone salvage or palliative radiation were also found to have recurrent disease. The author concluded that it was likely a combination of the radiation and recurrent disease that increased the risk of failure after ureteroneocystostomy.
