目的:探讨B超引导微创经皮肾穿刺造瘘,输尿管镜通过造瘘通道,气压弹道碎石术(MPCNL)治疗复杂性肾结石的疗效。方法:回顾性分析2006-06/2008-05采用B超引导MPCNL治疗32例复杂性肾结石的患者资料。结果:经单通道取石27例,二通道取石4例,三通道取石1例。结石总排净率96.88%(31/32)。术中及术后无大出血及严重并发症发生。结论:B超引导微创经皮肾输尿管镜取石术是一种安全、可靠的治疗复杂性肾结石的方法。
OBJECTIVE: To investigate the curative effect of B-guided minimally invasive percutaneous nephrostomy and ureteroscopy in the treatment of complex nephrolithiasis through the fistula tract and pneumatic lithotripsy (MPCNL). Methods: The data of 32 patients with complicated renal calculi treated with B-guided MPCNL were retrospectively analyzed. Results: There were 27 cases of single-channel stone removal, 4 cases of two-channel stone removal and 1 case of three-channel stone removal. Total stone discharge rate of 96.88% (31/32). No intraoperative and postoperative bleeding and serious complications occurred. Conclusion: B-guided minimally invasive percutaneous nephroureterectomy is a safe and reliable method for the treatment of complex renal calculi.
