[Laser now also to be used in organ-preserving kidney surgery?]

Abstract

Kidney surgery is subject to continuous change. Partial nephrectomy is the prevailing method for small and medium-sized tumours and proven to be superior to radical nephrectomy. The conventional technique usually includes clamping the renal vessels. The duration of the ischaemia caused determines the outcome of the remaining renal function. The shorter the ischaemic time the more likely the renal function will be preserved. Thus, new techniques are needed to abandon renal vessel clamping. Essential is a combination of good cutting abilities and assured haemostasis. To date, the commonly used techniques for cutting in partial nephrectomy only partially fulfil these requirements. Establishment of laser in urology offers a new surgical technique that combines both. In spite of the still limited data on laser use in kidney surgery, this method can be assessed favourably. Laser offers a possibility of both open and laparoscopic partial nephrectomy avoiding renal vessel clamping without additional risks or complications.
