concomitant treatment of ureteropelvic junction obstruction and renal calculi with robotic laparoscopic surgery and rigid nephroscopy
Urology, 2014Co-Authors: Ji Zheng, Zhansong Zhou, Zhiwen Chen, Xin Li, Weibing LiAbstract:Introduction The treatment of ureteropelvic junction obstruction (UPJO) and concomitant calculus poses a technically challenging situation. We present our experience with using rigid nephroscopy for renal calculi removal during robot-assisted pyeloplasy (RAP) for UPJO. Technical Considerations From December 2010 to November 2012, 25 patients with UPJO had RAP at our institution; 9 of those had concurrent renal calculi, which were simultaneously treated with rigid nephroscopy. For stone extraction, a rigid ureteroscope was passed through an assistant trocar under laparoscopic vision directly into a previously created pyelotomy. The stones were extracted using a rigid grasper or stone basket through the rigid ureteroscope. For the removal of the stones within the upper and lower calyces, the rigid ureteroscope was introduced into the incised renal pelvis through robotic trocars if the "assistant trocar" route failed. Complete stone clearance was achieved in 8 of 9 patients. Residual calculi in 1 patient were removed with a single session of extracorporeal shock wave lithotripsy. At the mean follow-up of 10.2 months, no patients had obstruction or recurrent stones. The mean operative time was 187.1 minutes, which was 40.9 minutes longer than the mean operative time in patients without renal calculi. There was no significant difference in blood loss, hospital stay, complications, and success rates between patients with and without renal calculi. Conclusion Our data suggest that the use of a concomitant rigid Nephroscope and RAP is a safe and feasible option for the treatment of UPJO complicated with renal calculi.

Use of Rigid Nephroscope for Laparoscopic Common Bile Duct Exploration—A Single-Center Experience
World journal of surgery, 2010Co-Authors: Muneer Khan, Syed Javid Farooq Qadri, Syed Sajad NazirAbstract:Background Increasingly, laparoscopic biliary surgeons are undertaking laparoscopic cholecystectomy and laparoscopic common bile duct exploration for patients with cholelithiasis and choledocholithiasis. In laparoscopic common bile duct exploration a flexible choledochoscope is ordinarily used, and with this instrument the surgeon usually fails to remove large impacted stones. In contrast with use of a rigid Nephroscope it is possible to remove all common bile duct stones irrespective of size and degree of impaction. The present study evaluates the efficiency of rigid Nephroscope for managing common bile duct stones laparoscopically.

The development of robotic percutaneous Nephroscope simulative system
Journal of Modern Urology, 2009Co-Authors: Wang Gong-xianAbstract:Objective To simulate the movements performed by available robot in percutaneous nephroscopy,and to explore the feasibility of executing surgical robots. Methods The authors inspected similar systems of the robotic assisted percutaneous nephroscopy,designed a model and produced one robot. Results According to the test,the model could successfully perform puncture on the velvet fruit,and the learning curve was relatively short. Conclusion As percutaneous Nephroscope has been widely used in major departments,robotic assisted percutaneous nephroscopy will have a bright future in urology.
