Experience of performing laparoscopic organ-preserving operations in treatment of kidney tumors

Abstract

Purpose: to conduct a comparative assessment of the effectiveness and safety of laparoscopic kidney resections for benign and malignant neoplasms with and without vascular isolation of the organ. Materials and methods: the research presents a comparative analysis of the direct results of treatment of 182 patients who underwent laparoscopic kidney resection. Among them there were 94 men (51,7 %) and 88 women (48,3 %). The average age was 61,6 ± 6,2 years. Two main methods were used: kidney resection with vascular isolation and without vascular ischemia. Surgical treatment was performed for malignant neoplasms in 152 cases (86,5 %) and for benign neoplasms in 24 cases (13,6 %). We used the methods of laparoscopic resection of the kidney with total vascular ischemia in 44 cases (24,2 %) and without vascular ischemia in 138 patients (75,8 %). Results: the average duration of surgery was 80 ± 18,5 minutes. The average duration of the operation with the use of vascular ischemia was 122,1 ± 17,5 minutes, without ischemia — 81,7 ± 10,6 minutes. The volume of intraoperative blood loss averaged 174,4 ± 20,1 ml, while this indicator when using the ischemic-free technique was 154,2 ± 15,7 ml, which is 32,9 % less (p> 0,05) than in cases with the use of vascular isolation (230,1 ± 20,8 ml). When using the technique of vascular isolation, the serum creatinine has increased for 16,2 ± 1,7 μmol / L (16,7 %), without vascular isolation 6,5 ± 1,5 μmol / L (6,7 %). Conclusion: laparoscopic kidney resections without vascular isolation are characterized by a lower volume of intraoperative blood loss, a shorter operation time and are not accompanied by an increase in the number of postoperative complications.
