目的:探讨非同步俯卧位螺旋CT定位行微创经皮肾镜取石的可行性。方法:对5例肾结石和4例输尿管上段结石共9例拟行微创经皮肾镜取石患者,术前两次行俯卧位螺旋CT扫描,分别测量皮肤标记穿刺点到结石及肾下极的层面距离、标记穿刺点到达肾收集系统的深度以及穿刺径路与背部平面(人体冠状面)的角度并进行统计学分析。结果:两次扫描测得的穿刺点到结石及肾下极距离差值分别是(0.56±0.77)mm(P=0.49)和(1.11±1.54)mm(P=0.06),穿刺深度及角度差值分别为(0.18±0.85)mm(P=0.84)和(-0.64°±0.55°)(P=0.27)。结论:非同步俯卧位螺旋CT定位行微创经皮肾镜取石切实可行。
Objective: To explore the feasibility of using minimally invasive percutaneous nephrolithotomy in non-synchronized prone position spiral CT. Methods: Nine patients with renal calculi and 4 patients with upper ureteral calculi underwent minimally invasive percutaneous nephrolithotomy. Two patients underwent preoperative spiral CT scan. The puncture points of skin markers were measured to the stones and the lower kidney electrode The distances between the puncture site and the renal collecting system, as well as the angles between the puncture path and the dorsal plane (coronal plane) were marked and statistically analyzed. Results: The differences of the distance from the puncture point to the lithiasis and the lower kidney electrode measured by two scans were (0.56 ± 0.77) mm (P = 0.49) and (1.11 ± 1.54) mm (P = 0.06) Values were (0.18 ± 0.85) mm (P = 0.84) and (-0.64 ° ± 0.55 °), respectively (P = 0.27). CONCLUSIONS: Non-synchronized prone-position helical CT positioning is practically feasible with minimally invasive percutaneous nephrolithotomy.
