Title: Clinical application value of swelling palace machine during ureteroscopic lithotripsy in the treatment of ureteral calculi combined with polyps
Abstract: Objective To evaluate the clinical value of swelling palace machine during ureteroscopic pneumatic lithotripsy in the treatment of ureteral calculi combined with polyps,in order to explore the surgery techniques.Methods Clinical date of 52 patients who underwent ureteroscopic pneumatic lithotripsy and were found with polyp surrounding ureter calculi were reviewed.Among them,18 cases were upper ureter stone and 34 cases were middle-lower ureteral stone.25 cases used swelling palace machine to inject normal saline for keeping clear operation view(swelling palace machine-assisted group).27 cases used a high handled water bag with artificial water injection(traditional pneumatic lithotripsy group).Double J stent was put in both groups.Total operation time,time of stone removal,stone clearance rate and surgery complications were compared between two groups.Results All operations were successful with no case transferred to open surgery.No ureter breakage or avulsion occurred in two groups.One case in traditional pneumatic lithotripsy suffered from ureter perforation.Total operation time in swelling palace machine-assisted group and traditional pneumatic lithotripsy group were 31.2±5.1 min VS 37.0±6.2 min(t=-3.68,P=0.00060.05).Time of stone removal were 6.5±1.4 min VS 9.4±1.5 min(t=-7.19,P=0.00000.05).Stone clearance rate were 100%(25/25) VS 96.3%(26/27) with upper ureter stone in one case of traditional pneumatic lithotripsy group immigrated to renal pelvis,which was treated by extraorgan shock wave lithotripsy after surgery.All patients in two groups received 3 months to 1 year follow-up.B-ultrasound showed no residual stones and postoperative ureteral stricture occurred in both groups.Conclusions Intraoperative infusion of saline by swelling palace machine with some gravel techniques can maintain a clear operation field and favor stone removal,resulting in less time of stone clearance during ureteroscopic pneumatic lithotripsy.It has important clinical value in the treatment of ureteral calculi combined with polyps.
