External ureteral catheter (EUC) and double-J stent are both commonly used to drain upper urinary tract in percutaneous nephrolithotomy (PCNL). We compared the outcomes of using EUC versus double-J stent in performing PCNL in patients with renal stones in our settings in order to identify a better technique for the management of renal stones in terms of postoperative stent-related symptoms.
This randomized controlled trial was conducted at the Department of Urology, PAEC General Hospital, Islamabad, from January 2020 to December 2020. A total of 80 patients of either gender between ages 18 and 70 years planned for PCNL were enrolled and randomized into group I (double-J stent) and group II (EUC). Outcomes of the procedure were compared in both groups.
There were 62.5% of patients in group I who demonstrated stent-related symptoms compared to 22.5% in group II (p=0.001). No statistically significant difference was noted in other outcome variables like urinary leak (10% vs. 20%, p=0.210), post-procedure fever (25% vs. 22.5%, p=0.793), mean analgesia requirement (60.8 mg vs. 58.5 mg, p=0.685), and mean length of hospital stay (3.9 days vs. 4.2 days, p=0.330).
Stent-related symptoms were demonstrated by a significantly lesser number of patients who underwent PCNL with EUC when compared with patients who underwent PCNL with double-J stent. For other outcome variables (urinary leak, post-procedure fever, mean analgesia requirement, and mean length of hospital stay ), no significant difference was noted among both the groups.
外输尿管导管（EUC）和双J支架管在经皮肾镜取石术（PCNL）中均常用于引流上尿路。我们比较了在我们的医疗环境中使用EUC与双J支架管进行PCNL治疗肾结石患者的结果，以便从术后支架相关症状方面确定更好的肾结石管理技术。
本随机对照试验于2020年1月至2020年12月在伊斯兰堡PAEC综合医院泌尿外科进行。共有80例计划接受PCNL的18至70岁患者入组，并随机分为I组（双J支架管组）和II组（EUC组）。比较两组的手术结果。
I组有62.5%的患者出现支架相关症状，而II组为22.5%（p = 0.001）。在其他结果变量方面，如尿漏（10%对20%，p = 0.210）、术后发热（25%对22.5%，p = 0.793）、平均镇痛需求量（60.8 mg对58.5 mg，p = 0.685）和平均住院时间（3.9天对4.2天，p = 0.330），未观察到统计学上的显著差异。
与接受双J支架管PCNL的患者相比，接受EUC PCNL的患者出现支架相关症状的人数明显较少。对于其他结果变量（尿漏、术后发热、平均镇痛需求量和平均住院时间），两组之间未观察到显著差异。
