Abstract:
Objective:To explore the application value of B-mode ultrasound combined with real-time color doppler ultrasound in percutaneous nephrolithotomy and provide guidance for clinical application.
Methods:A total of 150 patients underwent percutaneous nephrolithotomy from December 2015 to December 2017 in the People's Hospital of Lishui were selected.According to different ultrasound guidance methods, the patients were divided into two groups.The single group(70 cases) received B-guided puncture.In the combined group(80 cases), B-ultrasound combined with real-time color doppler ultrasound-guided puncture was applied.The incidence of complications and the success rate of lithotomy were compared between the two groups.The changes in renal artery blood flow parameters[end diastolic velocity(EDV), peak systolic velocity(PSV) and resistance index(RI)] before and after surgery in the combined group were observed.
Results:The incidence of complications in the combined group was 2.50%(2/80), which was lower than that in the single group[14.29%(10/70)](χ2=7.046, P<0.05). The success rate of stone extraction in the combined group was 98.75%(79/80), which was higher than that in the single group[85.71%(60/70)](χ2=9.336, P<0.01). The EDV and PSV of the renal interlobar arteries of the combined group before and after surgery had statistically significant differences (t=3.794, 5.385, all P<0.05), but the RI had no statistically significant difference (P>0.05). The EDV and PSV of renal segment arteries in the combined group before and after surgery had statistically significant differences (t=4.535, 4.884, all P<0.05), while the RI had no statistically significant difference (P>0.05). The EDV and PSV of renal aorta of the combined group before and after surgery showed no statistically significant differences (all P>0.05), while the RI showed statistically significant difference (t=4.360, P<0.05).
Conclusion:B-mode ultrasound combined with real-time color doppler ultrasound guidance for percutaneous nephrolithotomy can help reduce the incidence of complications and improve the success rate of stone extraction to a certain extent.
