Purpose: To evaluate the one-step prone split-leg position compared to the traditional prone position for percutaneous nephrolithotomy (PCNL).
Materials and Methods: This study retrospectively analyzed the clinical data for 102 patients with upper urinary tract calculi who underwent PCNL at our hospital from April 2019 to December 2022. All PCNL procedures were performed by the same senior urologist. According to different surgical positions, the patients were divided into a one-step prone split-leg position group (observation group, n = 39) and a traditional bladder lithotomy position followed by prone position group (control group, n = 63). Then, the two groups were compared regarding the time of catheter insertion and channel establishment, channel size, time required for double-J stent placement, total operative time, postoperative hospital stay, stone removal rate, secondary operation rate and postoperative complications.
Results: There was no significant difference in the preoperative baseline characteristics of the patients between the two groups (all P >.05). Patients in the observation group had shorter total operative times, higher stone removal rates (76.9% [30/39] vs. 57.1% [36/63], P =.042), and lower secondary operation rates (10.3% [4/39] vs. 28.6% [18/63], P =.029) than those in the control group. There were no significant differences in the time of working channel establishment, channel size, postoperative hospital stay, or postoperative complications between the two groups (all P >.05).
Conclusion: The one-step prone split-leg position is a safe and reliable surgical posture for treating upper urinary calculi in PCNL patients. It can not only shorten the overall operation time of PCNL but also improve the stone removal rate of the operation, thus reducing the secondary operation rate of multiple renal stones.
