Сomparative analysis of the effectiveness of ultrasound cavitation in laparoscopic kidney resection

The purpose of the study is a comparative analysis of the effectiveness of ultrasonic cavitation in kidney malignancies. Materials and methods. The study included 42 patients aged 32–80 years with kidney tumors of stage T1a-T1b in order to compare the effectiveness of various methods of dissection of kidney tissue: 22 patients underwent laparoscopic resection using conventional mono- and bipolar electrosurgical instruments; 20 patients underwent laparoscopic resection of the kidney using an ultrasound cavitation device (Fotek, model «Actiton B»). Both groups were statistically comparable in terms of gender, age, and stage of the disease. In all cases, a clear cell renal cell carcinoma (100 %) was verified during histological examination in both groups. Results and conclusion. The method of kidney resection using ultrasound cavitation to dissect the renal parenchyma is more effective in terms of nephron conservation compared to the use of conventional electrosurgical instruments. There was also a lower volume of blood loss in the case of ultrasonic cavitation. The duration and radicality of surgery in both groups did not differ.
