Extended pyelolithotomy is a technique applicable for removal of most staghorn, and large pelvic and caliceal calculi. Nephrotomy incisions can be avoided in many cases. The efficiency of extended pyelolithotomy in difficult cases can be improved by renal artery occlusion combined with regional renal hypothermia. Devascularization of the kidney produces softening of the renal substance, which facilitates stone removal. The operative method is described and 5 cases are presented.
扩大肾盂切开取石术是一种适用于大多数鹿角形结石以及较大的肾盂和肾盏结石取出的技术。在许多情况下可避免肾切开切口。对于困难病例，通过肾动脉阻断联合局部肾低温可提高扩大肾盂切开取石术的效率。肾脏去血管化可使肾实质软化，这有助于结石取出。本文描述了手术方法并介绍了5例病例。
