Using laser radiation in partial nephrectomy for renal tumors

In recent years, the number of organ-sparing operations for renal tumors has been increasing steadily due to comparable oncological outcomes and the desire to preserve functioning renal parenchyma. Another technique, which is becoming increasingly popular, is so-called zero ischemia partial nephrectomy, which allows bleeding to be controlled during the operation without clamping the renal artery, thus avoiding renal ischemic injury. One of the most interesting and promising instruments for partial nephrectomy is a laser radiation. It combines good cutting and coagulating properties, thus enabling partial nephrectomy to be carried out without vascular clamping. This literature review presents the physical basis of laser technology and evidence from published clinical studies on using of various types of laser radiation for partial nephrectomy. The prospects for further development of the technique are discussed.
