unilateral multiple renal congenital anomalies; a case report

Aims: the urinary tract is a site for common anomalies. ureteropelvic junction obstruction and double collecting system are among the most common anomalies in the body, but gathering all of these anomalies reported in our patient and being unilateral may be a rare entity. hereby, we report a case with such a rare condition.patient & methods: the patient is a 19-year-old army male who presented with left lower quadrant abdominal pain after blunt abdominal trauma, accompanied by gross hematuria. findings: ultrasonography suggested an ectopic pelvic left kidney with hydronephrosis and ureteropelvic junction obstruction with distal ureteral dilatation. exploration was done through a gibson’s retroperitoneal incision, and pyeloplasty accompanied by ureteroneocystostomy was carried out. conclusion: the collection of unilateral renal ectopia, double collecting system, lower moiety ureteropelvic junction obstruction, and finally ending to a common ureter with ureterovesical junction obstruction, seems to be a rare condition, but we found all of these in a young male.
