Ureterocalicostomy is usually a salvage procedure for recurrent pelvi-ureteric junction (PUJ) stricture or upper ureteric injury. It requires meticulous dissection of the upper ureter, and lower pole nephrectomy is considered an essential step to achieve a wide funneled and dependent ureterocaliceal anastomosis. We, hereby, highlight the importance of guillotine lower pole nephrectomy through a case report of recurrent PUJ stricture managed with ureterocalicostomy that failed due to the omission of lower pole nephrectomy.
