Abstract

Abstract : Introduction: Primary obstructed non‐refluxing megaureter, a type of congenitally dilated ureter, often resolves spontaneously. Surgery may be indicated in symptomatic cases; however, there are no reports of transvesicoscopic ureteral implantation and ureteroscopy for ureteral stones. Therefore, we describe the treatment of primary obstructed non‐refluxing megaureter and ureteral calculi using this technique. Case presentation: A 6‐year‐old Japanese girl was referred for abdominal pain and gross hematuria due to right megaureter with multiple stones in the renal lower‐pole calyces and ureter. She was diagnosed with primary obstructed non‐refluxing megaureter and ureterovesical junction obstruction. The stones were removed using mini‐percutaneous nephrolithotomy and transvesicoureteroscopic surgery, respectively. A narrow segment of the right ureter was cut, and transvesicoscopic ureteral plication and reimplantation were performed. The procedures were successful without postoperative complications. Conclusion: Transvesicoscopic ureteral reimplantation with ureteroscopy may be a safe, effective and minimally invasive surgical option for ureterovesical junction obstruction with ureteral stones.
