Objective: To report the case of a left complete triple ureter with ureteral pyelocalicial system draining independently into the bladder in a patient consulting for episodes of right renal colic.
Methods/results: 27-year-old female patient consulting for episodes of right renal colic. Several studies including intravenous urography and CT scan were performed revealing a right renal lithiasis and a double ureteral pyelocalicial system on the right side; the left kidney showed three pyelocalicial systems with three ureters, draining each of them separately into the bladder.
