Intraoperative Doppler flowmetry was used for localization of the intrarenal arteries. To reduce blood loss during nephrolithotomy, a neodymium-yttrium aluminum garnet (YAG) laser beam was used clinically as a cutting instrument. The combination of intraoperative localization of intrarenal arteries by Doppler flowmetry and cutting through renal parenchyma using the neodymium-YAG laser beam was used in 7 patients with stag-horn calculi or recurrent stones. The average blood loss was only 185 ml. Postoperative renal function was normal. Intravenous pyelograms revealed prompt function and no evidence of contrast extravasation. The data indicate that this technique is effective, diminishes blood loss, and does not impair renal function.
术中使用多普勒血流仪定位肾内动脉。为减少肾切开取石术期间的失血，临床上使用钕钇铝石榴石（YAG）激光束作为切割器械。7例鹿角形结石或复发性结石患者采用了多普勒血流仪术中定位肾内动脉并使用钕-YAG激光束切开肾实质的联合方法。平均失血量仅为185毫升。术后肾功能正常。静脉肾盂造影显示肾功能迅速恢复且无造影剂外渗迹象。数据表明该技术有效，可减少失血且不损害肾功能。
