A total of 82 patients with complex renal calculi were selected, who underwent percutaneous nephrolithotripsy guided by B-ultrasound. The average operation time was 101.52 ±8.35 minutes, the average intraoperative bleeding volume was 132.86 ±7.22 ml, the average hospital stay was 10.47 (±1.68) days, the primary calculi clearance rate was 85.37% (70 cases), and the secondary calculi clearance rate was 95.12% (78 cases). Postoperative complications occurred in 18 (21.95%) cases, including fever in 13 (15.85%), residual stone in 4 (4.88%), and delayed bleeding in 1 (1.22%) case. The findings show that percutaneous nephrolithotripsy guided by B-ultrasound is safe and effective in the treatment of complex renal calculi and is suitable for popularisation and application in primary hospitals.
