Wound Process in Kidney Parenchyma Following Traditional Partial Nephrectomy Versus Laserassisted Partial Nephrectomy in Experiment

Abstract

The purpose of the study To compare the morphological changes in renal tissue following traditional partial nephrectomy versus laserassisted partial nephrectomy. Material and methods 100 mature male Wistar rats were included in experiment. A diode laser-emitting light at a wavelength of 970 nm of ЛСП «ИРЭ-Полюс» model ЛСП 0,97/10 laser was used for partial nephrectomy. General conditions of animals and morphological changes in renal tissue following traditional partial nephrectomy with warm ischaemia and laserassisted partial nephrectomy were evaluated during the experiment. Results and their discussion the reparation of kidney parenchyma in a resection margin was more fluent after laserassisted partial nephrectomy with the laser-emitting light at a wavelength of 970 nm in continuous-wave mode. Also there were not any morphological changes in renal tissue following laserassisted partial nephrectomy. Conclusion the comparative analysis showed that the diode laser-emitting light at a wavelength of 970 nm is promising method for using in clinical practice
