Abstract:Objective:To evaluate the clinical efficacy and safety of percutaneous nephrolithotomy (PNL) under the guidance of X-ray in the treatment of complex renal calculi with a combination of ultrasonic and pneumatic lithotripsy.Methods:Between 2006 and 2011, 458 patients (285 males and 173 females) with complex renal calculi underwent PNL. Of these cases, staghorn calculi were found in 156 cases, horseshoe kidney calculi in 5cases, calyceal diverticulum stones in 18 cases, pediatric kidney calculi in 38 cases, solitary kidney calculi in 45 cases, and the remaining 196 cases were multiple or diameter more than 30 mm calculi. Under general anesthesia, an ureteral stent was placed to the ureter by cystoscopy. With the prone position, percutaneous access was established by placement of an access needle into the intended calix under ultrasonographic or fluoroscopic guidance. Ultrasonic and pneumatic probes were combined through nephroscopy for lithotripsy.Results:A single tract was used in 439 patients, and two or three tracts in the remaining 19 patients. One step procedure to remove the stones was in 317 patients, the need for secondary intervention was in 124 patients, 16 for third procedure, and 1 for fourth procedure. The mean time of operations were 30-150(75±28)min. Major complications were rare, haemorrhage occurred in 7 patients after operation, which were successfully treated with blood transfusion and super-selective arterial embolization. Sepsis occurred in 3 cases after PNL,these 3 patients were recovered after conservative treatment.The mean postoperative hospitalization stay were 5.6(3-26) days.The stone cleared rate was 85.8%(393/458)at one month follow-up. 28 cases needed ESWL after PNL. The stone-free rate in all was 90.2% (413/458)at 6 month follow-up.Conclusions:The combination of ultrasonic and pneumatic intracorporeal lithotripsy under the guidance of X-rayappears is to be efficacious and safety for removing complex renal calculi.
