[THE RESULTS OF LAPAROSCOPIC PARTIAL NEPHRECTOMY DEPENDING ON THE TYPE OF ACCESS AND THE TUMOUR SIZE]

Aim - retrospective comparative analysis of results of laparoscopic partial nephrectomy (LPN) depending on the type of access and the size of the tumor. The study included 170 patients undergoing LPN during the period from 2010 to 2015 years. Among the patients was 108 males (63.5%) and 62 women (36.5%) ranging in age from 17 to 80 years (average age 56,6±0.9 years). Depending on the type of access and the size of the tumor patients divided into 4 subgroups-154 patients who performed transperitoneal LRP, 16 patients undergoing retroperitoneal partial nephrectomy, 117 patients with tumor less than 4 cm and 53 patients with tumor more than 4 cm. There were no fatalities in 170 patients undergoing LRN, 3 (1.8±1.0%) patients had conversion, two of which involved open partial nephrectomy and one case involved radical nephrectomy. The duration of the surgery ranged 50-250 min (115.4±2.3 min on average), while time of insufflation ranged 40-240 min (103.8±2.2 min on average). Average intraoperative blood loss constituted 120.6±6.3 ml (15-400 ml), average time of warm ischemia was 22.01±0.83 min. Different intraoperative complications were observed in 4 patients (2.4%), in the postoperative period in 25 patients (14.7±2.7%). Patients spent 2-16 days (average 4.11±0.16 days) in the hospital after surgery. LRP can perform as transperitoneal а retroperitoneal approaches. The large size of kidney tumour, are not a contraindication for laparoscopic organ-preserving surgery and can successfully performed in experienced hands and specialized centres.
