CLINICAL EFFECTIVENESS ASSESSMENT OF MODIFIED METHOD OF LAPAROSCOPIC PARTIAL NEPHRECTOMY
22 laparoscopic partial nephrectomy (LPN) was performed on T1 stage renal cell carcinoma (RCC) patients. In all patients warm ischemia method was used. Main group consisted of 12 patients (54.5%) whose pelvicaliceal system (PCS) of the kidney was opened during LPN. These patients underwent LPN modification, which consisted of excluding of separate PCS suture repair of the kidney after tumor excision. This technique allowed reducing WIT. Tumor bed excision was sutured using “sliding clip” technique. Control group consist of 10 (45.5%) patients whose PCS were not opened during LPN. Mean age in the main and control groups was 59.3+10.6 (range 42-77) and 52.5 +11.7 (range 33-68), mean tumor size – 39.3+7.5 mm (range 29-57) and 39.5 + 7.5 mm (range 25-52), mean RENAL nephrometry sum - 7.6+1.2 (range 6-10) and 6.8+0.9 (range 5-8), mean WIT – 12.6+2.3 min.(range 9-16) and 11.3+3.1 (range 6-15), mean blood loss – 207.5+237.9 ml (range 50-800) and 97+32.7 ml (range 50-150) respectively. Using of modified technique of LPN reduces warm ischemia time and expands indications to LPN.
