[Ectopic ureter without urinary incontinence despite ureteric orifice in the vestibulum: report of one case]

This is one case of ectopic ureter which lacked urinary incontinence despite ureteric orifice in the vestibulum.

A 20-year-old woman complained of miction pain. On examination, we found a small orifice in the vestibulum. DIP revealed slight hydronephrosis in the left contracted kidney and normal pyelogram in the right kidney. On cystoscopy, the bilateral ureteral orifices were normal, but we found the head of a catheter placed in the orifice of the vestibulum was passing under the mucosa of the bladder. The abnormal lumen was recognized by introducing an opaque medium through a catheter placed into the orifice of the vestibulum. The diagnosis was an abnormal left ureteral ectopic opening into the vestibulum with left complete duplication of renal pelvis and ureter. Left heminephro-ureterectomy was performed. Some discussions about the ectopic ureteral orifice without incontinence were conducted.
