Abstract：Objective To compare the clinical effect of two different minimally invasive surgical treatments for patients with larger bladder stones (diameter 2.5 cm or above), and to explore the advantages of minimally invasive percutaneous transurethral cystostomy in the treatment of larger bladder stones.Methods The clinical data of 80 patients with bladder stones (above 2.5 cm in diameter) were retrospectively analyzed. According to the treatment, 40 patients were divided into the percutaneous group and transurethral group respectively.<<< In the percutaneous group, percutaneous cystostomy combined with pneumatic lithotripsy was used while in the transurethral group, transurethral pneumaticlithotripsy was performed. The clinical efficacy was compared and analyzed between the two groups>>>.Results The percutaneous group was superior to the transurethral group in terms of operation time, catheterization time and voiding time. The amount of bleeding loss was smaller in the percutaneous group than in the transurethral group (P<0.01). The first-stage stone clearance rate was 97.5% in the percutaneous group and 85% in the transurethral group. The total effective rate was 92.5% in the transcutaneous group (P<0.05), higher than in the transurethral group (P<0.05).Conclusions Percutaneous pneumatic lithotripsy is more effective for the treatment of bladder stones with a diameter of 2.5 cm or above than transurethral pneumatic lithotripsy, and this method is worthy of popularization and application in clinical practice.
