Abstract：Objective To compare the effect of ultrasound-guided standard and multi-channel percutaneous nephrolithotomy in the treatment of renal calculi. Methods Retrospective analysis was made on the clinical data of 100 patients with renal calculi who received ultrasound-guided percutaneous nephrolithotomy in Anhui Provincial Corps Hospital from June 2020 to June 2022. Among them, 50 patients underwent standard channel percutaneous nephrolithotomy (standard group) and 50 patients underwent multi-channel percutaneous nephrolithotomy (multi-channel group). Operation duration, lithotomy duration, blood loss, length of hospital stay, visual analogue score (VAS) on the first day after surgery, stone clearance rate, and postoperative complications were compared between the two groups. Results The operation time, lithotripsy time and intraoperative blood loss in the multi-channel group were lower than those in the standard group (P<0.05). The visual analogue scale (VAS) score of the multi-tract group was lower than that of the standard group on the first day after operation (4.41±1.14 vs. 5.03±1.22), and the stone clearance rate was higher than that of the standard group(96.0% vs. 82.0%), with statistically significant difference (P<0.05). The total incidence of postoperative complications in the multi-tract group was 2.0%, which was lower than 14.0% in the standard group, whose difference was statistically significant (P<0.05). Conclusions Compared with ultrasound-guided standard percutaneous nephrolithotomy, the application of ultrasound-guided multi-channel percutaneous nephrolithotomy in the treatment of renal calculi is helpful to save operation time, reduce surgical injury, improve stone clearance effect, and reduce the risk of postoperative complications.
