F4.8可视穿刺辅助微通道经皮肾镜治疗肾盏憩室结石的临床应用

Clinical application of F4.8 visual puncture auxiliary micro channel percutaneous nephroscopy in treatment of renal caliceal diverticular calculi

目的探讨F4.8可视穿刺辅助微通道经皮肾镜(mPCML)治疗肾盏憩室结石的安全性和有效性。方法回顾性分析2017年1月至2021年8月该院采用F4.8可视穿刺辅助mPCML治疗的17例肾盏憩室结石患者的临床资料。结果17例肾盏憩室结石患者均采用F4.8可视穿刺辅助mPCML取石,通道建立时间为(6.9±2.3)min,手术时间为(48.4±19.5)min;术后3例(17.6%)患者出现发热,12例(70.6%)患者出现血红蛋白减少,平均减少(6.2±3.7)g/L。术后无症状率100%,出院时结石清除率为94.1%(16/17)。术后3个月复查,14例(82.4%)患者憩室消失,3例(17.6%)患者憩室变小。结论F4.8可视穿刺辅助mPCNL在治疗肾盏憩室结石方面具有很好的安全性和有效性。

Objective To investigate the effectiveness and safety of F4.8 visual puncture auxiliary micro channel percutaneous nephroscope(mPCNL)for treating renal caliceal diverticular calculi.Methods Retrospective analysis was conducted on the clinical data of 17 patients with renal caliceal diverticular calculi treated with F4.8 visual puncture auxiliary mPCML in this hospital from January 2017 to August 2021.Results Seventeen patients with renal caliceal diverticular calculi all adopted F4.8 visual puncture auxiliary mPCNL.The channel establishment time was(6.9±2.3)min,and the operative time was(48.4±19.5)min.Three cases(17.6%)developed fever after operation.Twelve cases(70.6%)developed the hemoglobin decrease and the mean hemoglobin decrease was(6.2±3.7)g/L.The postoperative symptom-free rate was 100%and the stone removal rate of hospital discharge was 94.1%(16/17).In the reexamination at the postoperative 3 months,the diverticulum disappeared in 14 cases(82.4%)and was decreased in 3 cases(17.6%).Conclusion F4.8 visual puncture auxiliary mPCNL has the excellent safety and effectiveness for treatment of renal caliceal diverticular calculi.
