Since Helal and Jackman developed the mini-percutaneous ("mini-perc") percutaneous nephrolithotomy (PCNL) for the treatment of pediatric renal lithiasis various authors have used is technique in adults with the aim to preserve renal parenchyma and diminish morbidity associated with the standard PCNL.
We describe the surgical technique of "mini-perc" PCNL in the treatment of renal lithiasis.
We review various case series from the literature of "mini perc" PCNL for the treatment of adult renal lithiasis, its current indications, percentages of stone free patients, and associated problems, mainly the required instruments.
Morbidity associated with "miniperc" PCNL seems to be lower than with the standard PCNL, but the use a smaller calibre tract with the only aim to preserve renal parenchyma does not offer advantages. It is a complementary technique to the standard PCNL; however, the diameter of the percutaneous access is not well defined yet and depends on the calibre of the instruments used.
自从赫拉尔（Helal）和杰克曼（Jackman）开发出用于治疗小儿肾结石的微创经皮肾镜取石术（“mini-perc”经皮肾镜取石术）以来，许多作者已在成人中使用该技术，目的是保留肾实质并降低与标准经皮肾镜取石术相关的发病率。
我们描述了“mini-perc”经皮肾镜取石术治疗肾结石的手术技术。
我们回顾了文献中关于“mini perc”经皮肾镜取石术治疗成人肾结石的各种病例系列、其当前适应症、结石清除患者的百分比以及相关问题，主要是所需器械。
“miniperc”经皮肾镜取石术相关的发病率似乎低于标准经皮肾镜取石术，但仅以保留肾实质为目的使用较小口径的通道并无优势。它是标准经皮肾镜取石术的一种补充技术；然而，经皮穿刺通道的直径尚未明确界定，且取决于所使用器械的口径。
