To evaluate a novel, simplified technique for TRUE supine percutaneous nephrolithotomy (PCNL) that omits the use of bolsters or stirrups, utilizing a novel anatomical landmark ("Dixit line") for initial puncture. The outcomes of this technique are compared with those of the traditional supine PCNL approach.
A retrospective observational study was conducted on 400 patients who underwent supine PCNL for renal or upper ureteric stones between January 2020 and January 2024. All procedures were performed by a single urologist at a tertiary care center. Patients were divided into two groups: One treated with the novel technique and the other with the traditional technique. Data on demographics, stone characteristics, intraoperative variables, and postoperative outcomes were collected and analyzed.
The novel technique group demonstrated significantly shorter operative times (53 ± 10 min vs. 70 ± 15 min, < 0.01), demonstrating enhanced procedural efficiency. Demographic and stone characteristics, as well as most intraoperative and postoperative outcomes, showed no significant differences between the two groups. However, the novel technique group exhibited a trend toward quicker discharge times (1.8 ± 0.5 days vs. 2.1 ± 0.7 days, = 0.05).
The novel TRUE supine PCNL technique, which excludes bolsters or stirrups and uses the "Dixit line" for initial puncture may serve as an effective alternative to traditional methods, improving efficiency while maintaining safety.
评估一种新颖、简化的真正仰卧位经皮肾镜取石术(PCNL)技术,该技术省略了使用支撑垫或马镫,利用一种新颖的解剖标志(“迪克西特线”)进行初始穿刺。将该技术的结果与传统仰卧位PCNL方法的结果进行比较。
对2020年1月至2024年1月期间因肾或上段输尿管结石接受仰卧位PCNL的400例患者进行回顾性观察研究。所有手术均由三级医疗中心的一名泌尿外科医生进行。患者分为两组:一组采用新技术治疗,另一组采用传统技术治疗。收集并分析人口统计学、结石特征、术中变量和术后结果的数据。
新技术组的手术时间明显更短(53±10分钟对70±15分钟,<0.01),表明手术效率提高。两组的人口统计学和结石特征以及大多数术中及术后结果均无显著差异。然而,新技术组的出院时间有更快的趋势(1.8±0.5天对2.1±0.7天,=0.05)。
新颖的真正仰卧位PCNL技术,不使用支撑垫或马镫,使用“迪克西特线”进行初始穿刺,可能是传统方法的有效替代方案,在保持安全性的同时提高了效率。
