Endoscopic combined intrarenal surgery after anti‐reflux operation is rarely performed.
Case presentation
A 37‐year‐old female was referred to our hospital for treatment of left renal stone. She underwent anti‐reflux surgery (Cohen reimplantation) for left vesicoureteral reflux at the age of 10 years. Computed tomography revealed a 17 × 11 mm left inferior calyceal calculus. The patient received retrograde double‐J stent insertion under radiographic guidance and underwent ultra‐mini endoscopic combined intrarenal surgery without ureteral access sheath. The patient was discharged on postoperative Day 5 with no postoperative complications. Postoperative cystography showed no recurrence of vesicoureteral reflux. One month after the operation, kidney–ureter‐bladder radiography and computed tomography scan revealed no residual stones or hydronephrosis.
Conclusion
Ultra‐mini endoscopic combined intrarenal surgery without ureteral access sheath is an effective method for treating renal stones after Cohen reimplantation.
