Title: [Percutaneous nephrolithotripsy with pneumatic and ultrasonic power under B-type ultrasound guidance for treatment of renal calculi in non-dilated collecting system].
Abstract: To evaluate the efficacy and safety of management of renal stone in non-dilated collecting system by percutaneous nephrolithotripsy (PCNL) under ultrasound guidance.From September 2003 to April 2005, 132 cases of renal stone in non-dilated collecting system were performed by percutaneous nephrolithotripsy. A stent was first inserted into the pelvis through cystoscope, and saline was instilled to dilate collecting system. Antegrade percutaneous access was obtained by B-type ultrasound guidance. A combination pneumatic and ultrasonic lithotrite were used to disintegrate and remove stone under direct vision. Clinical data including operation time, complications and stone free rate were analyzed retrospectively.The percutaneous renal access was successfully established under B-type ultrasound guidance in all patients, immediate phase I lithotripsy was performed in 129 cases and delayed phase II lithotripsy in 3 cases. Operation time ranged from 70 to 130 minutes, average time was (89 +/- 11) minutes, 3 cases were supported by blood transfusion, severe complications did not occur during nephrolithotripsy. Stones were cleared in 114 out of 132 cases (86.4%) during immediate phase I lithotripsy, residual stone fragment was found in 18 cases who received second PCNL or adjuvant extracorporeal shock wave lithotripsy.The management of renal stone in non-dilated collecting system using PCNL appears to be efficacious and safe under B-type ultrasound guidance.
