A case of retrocaval ureter with robot‐assisted ureteral reconstruction

Abstract

Introduction: Retrocaval ureter is a rare congenital anomaly that causes ureteral obstruction. Because of the rarity of retrocaval ureter, only a few cases of open, laparoscopic, or robot-assisted surgery have been reported. We herein report a case of retrocaval ureter that was successfully reconstructed with robot-assisted surgery. Case presentation: A 24-year-old woman was incidentally diagnosed with right hydronephrosis on ultrasonography. Computed tomography revealed retrocaval ureter, and the right hydronephrosis was attributed to the retrocaval ureter. The patient underwent robot-assisted right ureteral reconstruction in the left lateral decubitus position. No intraoperative or postoperative complications occurred, and no right hydronephrosis was observed 6 months after the operation. Conclusion: The present case demonstrated the feasibility and efficacy of robot-assisted ureteral reconstruction for retrocaval ureter.
