B超引导下经皮肾穿刺微造瘘治疗肾结石

Treatment of renal calculi with minimally invasive percutaneous nephrolithotomy guided by ultrasound

目的:探讨运用超声引导经皮肾穿刺微造瘘治疗肾结石(MPCNL)的疗效及适应证。方法:回顾性分析运用超声引导对30例肾结石患者共31只肾进行MPCNL治疗的资料。结果:30例患者肾穿刺成功率96.8%(30/31),满意放置导管造瘘成功率93.5%(29/31)。全部病例术后解除结石梗阻。结论:B超引导下经皮肾穿刺微造瘘治疗肾结石成功率高,创伤小,安全,可靠。值得临床上推广使用。

Objective：To evaluate the therapeutic effect and adaptability of minimally invasive percutaneous nephrolithotomy （MPCNL） guided by ultrasound.Method：30 patients with renal calculi,who were treated with MPCNL guided by ultrasound from October 2005 to April 2006, were retrospectively analyzed.Results：The success rate of which the introducer needle tip was correctly positioned at the target point inside kidney was 96.8%（30/31）, and the catheter has been placed satisfactorily was 93.5%（29/31）.The successive rate or single puncture is very high, up to 95%, free from block in all cases after operations. Conclusions：A high success rate and less trauma were the merits of MPCNL, the technique is claimed to be safe and reliable, and it is worthwhile to be widely used.
