微创经皮肾镜取石术治疗肾下盏结石

摘要

Objectives To investigate the viability and clinical outcome of minimally invasive percutaneous nephrolithotomy (M PCNL ) in treating lower caliceal calculi .M ethodsWe retrospectively reviewed the clinical outcome and complications of 28 patients w ho underwent M PCNL for lower caliceal calculi from March 2009 to April 2013 . ResultsOf 48 cases ,83% (40/48) were rendered stone-free at 1 session .A second-look was needed in 4 cases .ESWL in 3 case ,untreatment in 1 case ,respectively .1 nephrostomy tract was required in all patients ,renal ac‐cess was obtained through an middle calyx in 10 cases ,a lower calyx in 18 .F16 renal access was in 18 cases ,F18 in 30 .Average operative time was 95 minutes ,blood loss volume was 123 ml ,average hospitalization stay was 10 .5 days ,no other major complications were noted . C onclusions Minimally invasive percutaneous nephrolithotomy is a alternative of treating lower caliceal calculi .It may offer advantages with respect to safety ,less invasion ,and easy recovery .%　　目的 探讨微创经皮肾镜取石术治疗有症状肾下盏结石的可行性与临床疗效。方法 我们对在2009年3月至2013年4月期间，接受了微创经皮肾镜取石术治疗的48例肾下盏结石患者的临床疗效及并发症进行回顾性分析。结果 在48例患者中，一期结石清除率为83％（40／48），4例需要二期取石，3例需要体外冲击波碎石，1例未处理。所有患者均为单通道取石，10例患者为中盏通道，其余患者均为下盏通道，F16通道18例，F18通道30例。平均手术时间为95min，平均住院天数为10．5天，术中平均出血量为123ml，其余没有出现大的并发症。结论 微创经皮肾镜取石术可以作为治疗有症状肾下盏结石的一种方法，它具有安全，微创，恢复快等优点。
