■经皮肾镜取石术(PCNL)是治疗大于2cm大小的肾结石的一线治疗方法,具有较低的发病率和较快的术后恢复的优点。建立肾造口术是PCNL的主要步骤之一。它可以通过单步扩张或通过多步串行扩张技术来完成。
■为了比较单步扩张技术与连续扩张技术经皮肾镜取石术的结果并评估其疗效,透视时间,输血率,住院时间(术后)和并发症发生率。
■这是一项前瞻性研究,样本量为100,其中50名患者接受了一步扩张,其他50名患者接受了连续扩张技术。这些患者根据他们的人口统计学特征进行了分析,肾通路时间,检查的总透视时间,术后血尿,术后住院时间和手术后并发症。使用统计工具分析和报告数据。
■两组患者的人口统计学特征和结石特征相当。平均进入道扩张时间,其中一组患者的平均总透视时间显著减少.需要输血,两组术后并发症发生率差异无统计学意义。
■两种方法都是安全和有效的尿道扩张。然而,PCNL可以通过一步扩张成功进行,并具有更短的肾脏进入时间的附加优点。较少的辐射暴露。两组患者术中出血量和术后住院时间差异无统计学意义。
UNASSIGNED: Percutaneous nephrolithotomy (PCNL) is the first line treatment for treating kidney stones larger than 2 cm size with the advantages of lower morbidity and faster post-operative recovery. Creation of a nephrostomy access is one of the major steps of PCNL. It can be done either by single-step dilatation or by multi-step serial dilatation technique.
UNASSIGNED: To compare the outcome and evaluate the efficacy of percutaneous nephrolithotomy done by single-step versus serial dilatation technique with specific reference to access time, fluoroscopy time, rate of blood transfusion, length of hospital stay (post-op) and complication rate.
UNASSIGNED: It was a prospective study with a sample size of 100 where 50 patients underwent one-step dilatation and other 50 patients underwent serial-dilatation technique. These patients were analysed on the basis of their demographic profile, renal access time, total fluoroscopy time for access, post-operative haematuria, duration of post-operative hospital stay and complications after operative procedure. Data was analysed and reported using statistical tools.
UNASSIGNED: Demographic profile of the patients and stone characteristics were equivalent between two groups. Mean access tract dilatation time, mean total fluoroscopy time were significantly less in one of the groups. Requirement of blood transfusion, and post-operative complications rate were not significant between two groups.
UNASSIGNED: Both methods are safe and effective for tract dilatation. However, PCNL can be successfully performed by one-step dilatation with the added advantages of lesser time of renal access, lesser radiation exposure. Blood loss and hospital stay after operative procedure were not statistically significant between two groups.
