ABSTRACT
Objective@#To evaluate the safety and effectiveness of ultrasound-guided percutaneous nephrolithotomy (PCNL) accessed by SVOF-principle and two-step puncture techniques.@*Methods@#A total of 838 cases with upper urinary stones underwent percutaneous nephrolithotomy successfully accessed by ultrasound-guided between June 2007 and December 2015 at Department of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology. Of all cases were divided in two groups hydronephrosis calyces puncture group include 425 cases and SVOF-principle puncture group include 413 cases. The access establishment time, operation time, stone free rate (SFR), postoperative complications, and postoperative hospitalization time between the two groups we compared by t test or χ2 test.@*Results@#Statistically significant differences were observed between hydronephrosis calyces puncture group and SVOF-principle puncturegroup in the first access establishment time ((16.5±8.4) minutes vs. (11.2±5.9) minutes, t=3.931, P=0.013), one-stage SFR (74.3% vs. 85.7%, χ2=16.868, P=0.000), postoperative hospitalization time ((6.4±2.1) days vs. (4.8±1.8)days, t=4.574, P=0.000), transfusion rate (7.1% vs. 2.9%, χ2=8.027, P=0.006), and embolization rate (3.3% vs. 1.0%, χ2=5.390, P=0.020). There were no statistically significant differences in operation time, total SFR, postoperative fever and sever infection between these two groups (all P>0.05). In both two groups, no serious complications such as peripheral organ injury and death occurred.@*Conclusions@#PCNL accessed guided by ultrasound with SVOF-principle and two-step puncture techniques has advantages of quick puncture location, high stone free rate, fewer complications and fast recovery. This technique is an effective and safe treatment option for upper urinary stones and deserved promotion and application in clinic.
