CT三维重建技术在泌尿系结石术前诊断及定位中的应用(1)
[摘要] 目的 探討CT三维重建技术(CTU)在泌尿系结石术前诊断及定位中应用的实用性及准确性。 方法 将2017年1月～2019年12月我院泌尿外科收治的70例行PCNL的泌尿系结石患者随机分为观察组35例和对照组35例。观察组术前行CT尿路三维重建(CTU)检查，对照组术前行静脉肾盂造影(IVP)检查。术前通过不同方法检查，分别设计PCNL穿刺通道，比较两组在一次穿刺成功率、手术时间、术中出血量、结石取净率以及两组术后并发症的发生率等方面的差异。 结果 所有患者均成功完成PCNL，其中两组的手术时间和术中出血量比较，差异有统计学意义(P<0.01)。两组的一次穿刺成功率和结石取净率比较，差异有统计学意义(P<0.05)。观察组术后并发症总发生率低于对照组，差异有统计学意义(P<0.05)。 结论 术前行CT尿路三维重建(CTU)，精准设计PCNL穿刺通道，在PCNL中的实用性、精准性、安全性优于静脉肾盂造影(IVP)检查，值得推广。

[Abstract] Objective To explore the practicability and accuracy of the application of CT three-dimensional reconstruction technology in the preoperative diagnosis and localization of urinarylithiasis. Methods 70 patients with urinarylithiasis admitted to and treated in Department of Urology of our hospital from January 2017 to December 2019 who received percutaneous nephrolithotomy (PCNL) were randomly divided into the observation group (n=35) and the control group (n=35). The observation group had a CT urography (CTU) with three-dimensional reconstruction before operation， while the control group underwent intravenous pyelography (IVP) before operation. Since different methods were adopted for examination， the puncture approaches were respectively designed for PCNL before operation， and the differences between the two groups in the success rate of one-time puncture， the operation time， the intraoperative blood loss， the stone clearance rate and the incidence rate of postoperative complications were compared. Results All the patients successfully received PCNL. Among which the differences between the two groups in the operation time and the intraoperative blood loss were statistically significant(P<0.01). The differences between the two groups in the success rate of one-time puncture and the stone clearance rate were statistically significant(P<0.05). Compared with the control group， the overall incidence rate of postoperative complications in the observation group was lowerand the difference was statistically significant (P<0.05). Conclusion Accurate design of puncture approaches for PCNL through CTU with three-dimensional reconstruction before operation is superior to IVP in practicability， accuracy and safety， which is worthy of promotion., http://www.100md.com(张晨辰)
