Abstract: Objective：To investigate the clinical effect of onestage combination therapy laparoscope surgery to perform nephrorrhaphy and ureteroscopic lithotripsy surgery to treat repeated ureteropelvic junction obstruction (UPJO) with renal calculus.Method：The surgical procedure including one double “J” ureteral catheter type F6 placed into renal pelvis was performed on one case of UPJO combined with renal calculus.Result：The surgery was successfully completed without serious complications,such as heavy bleeding and peripheral organ damage.The whole operation lasted 155 minutes including about 65 minutes of removal of renal calculus.There was about 50 ml of bleeding during the procedure.A complete inspection by flexible ureteroscope on repeated renal pelvis showed no blind spots.After the surgery,reviewed KUB showed the removal rate of renal calculus was 100%.After removing the double “J” tube,the examination of the repeated renal showed significantly reduced hydronephrosis.Conclusion：Onestage combination therapy of laparoscope surgery to perform nephrorrhaphy and ureteroscopic lithotripsy is safe and efficacy,it can be adopted as an ideal therapy to treat the case of UPJO combined with renal calculus.
