An atrophic crossed fused kidney with an ectopic vaginal ureter causing urine incontinence.

An ectopic vaginal ureter is an infrequent cause of urinary incontinence. Most cases are associated with a duplex kidney in which the lower moiety ureter drains into the bladder. Occasionally, some cases of ectopic kidney with single vaginal ectopic ureter can occur. In this study, we present a case of chronic continuous urine incontinence caused by the extremely rare combination of a fused-crossed kidney and a single vaginal ectopic ureter. Laparoscopic nephroureterectomy was carried out smoothly and uneventfully. In our experience, laparoscopic navigation and surgery can be valuable tools to delineate and manage unusual congenital anomalies.
