Introduction: Ureteropelvic junction obstruction is often associated with renal calculus formation. However, there is no report of using robot-assisted laparoscopic pyeloplasty combined with percutaneous endoscopic surgery for ureteropelvic junction obstruction and renal calculi in a partial duplex system.
Case presentation: A 19-year-old female patient with lower moiety ureteropelvic junction obstruction and renal calculi in a partial duplex system was referred to our hospital because of left lumbar pain, left acute pyelonephritis, and an increase in left renal calculi during follow-up at the referral hospital. To prevent the complication of percutaneous nephrolithotripsy following pyeloplasty, robot-assisted laparoscopic pyeloplasty combined with percutaneous endoscopic surgery was performed. Two years after surgery, the patient reported no left lumbar pain.
Conclusion: The combination of robot-assisted laparoscopic pyeloplasty and percutaneous endoscopic surgery can be proposed as a safe and less-invasive treatment option for ureteropelvic junction obstruction and renal calculi in a partial duplex system.
