Abstract:
Objective To evaluate the clinical efficacy of ultrasound-guided percutaneous pneumatic nephrolithotomy combined with ultrasonic lithotripsy in the treatment of renal calculi.Methods Fifty-nine patients with complicated renal calculi(ranged from 2.8 to 7.0 cm in diameter measured by KUB),including 36 patients with unilateral calculi and 23 patients with bilateral calculi,received percutaneous nephrolithotomy by using ultrasonic and pneumatic lithotripter(EMS Ⅲ),puncture hard wire,and mental dilator.A track from the skin surface into the kidney was established under the guidance of B ultrasonography.Results 82 tracks in the 59 patients were successfully established.The mean operation time was 90 minutes(45-150 minutes),and the management time of stones was 30-70 minutes.Residual stones were found in 15 kidneys and were removed by extracorporeal lithotripsy or two stage lithotripsy two weeks after operation.The clearance rate of stone in one session and two sessions was 82%(67/82) and 93%(14/15),respectively.Hospital stay was 5-15 days(mean,10 days).A follow-up of 1-6 months(mean,3.2 months) in 59 cases showed no severe bleeding,infections,and stone recurrence.Conclusions Ultrasound-guided percutaneous pneumatic nephrolithotomy combined with ultrasonic lithotripsy for complicated renal calculi is characterized by high efficiency,safety and minimal invasion.
