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.
