Simultaneous management for retrocaval ureter and ipsilateral renal stone using retroperitoneoscopic approach: report of a case

A 32-year-old male presented with a month history of right back and flank pain and a possibility of gross hematuria. As part of the initial evaluation abdominal ultrasound revealed marked right hydronephrosis. An excretion urogram showed delayed excretion of contrast material extending to the L4 level distally. Computed tomography revealed right renal pelvic stone and right retrocaval ureter. At surgery, a right-sided double-J ureteric stent was placed under fluoroscopic guidance. Retroperitoneal approach was used and flexible ureteroscopic removal of the right renal stone via a trocar port followed by retroperitoneoscopic right ureteroureterostomy using an intracorporeal suture technique. So far, none has reported simultaneous treatment of retroperitoneoscopic repair with retrocaval ureter and removal for the renal pelvic stone via a trocar port. We showed that this simultaneous management via a trocar port can be the better therapeutic choice for the renal stone with retrocaval ureter.
