Objective: Laparoendoscopic single-site (LESS) surgery represents the evolution of laparoscopy for the treatment of urologic diseases.
To investigate the safety and feasibility of LESS surgery in high-risk patients undergoing radical nephrectomy (LESS-RN) for renal cell carcinoma.
Methods and Results: A total of 20 high-risk patients were enrolled in this prospective study. Patients who underwent LESS-RN were compared to 26 high-risk patients after multitrocar laparoscopic radical nephrectomy (LRN).
Then the patients were divided into two groups: patients of high-anaesthetic risk (Group A: 7 after LESS-RN [Group A1] and 9 after LRN [Group A2] ) and patients of high surgical risk (group B: 13 after LESS-RN [Group B1] and 17 after LRN [Group B2] ).
The mean operative time in the group A1 and A2 was 162.1±34.3 min and 150.5±126.5 min, respectively. The mean hospital stay resulted to be 6.8±1.2 vs. 7.5±2.4 days in the two groups, respectively.
The mean operative time in the group B1 and B2 was 153±25.9 min and 122.5±81.3 min, respectively. The mean hospital stay resulted to be 3.8±0.8 vs. 4.2±1.4 days in the two groups, respectively. All LESS-RN were performed successfully without conversion to an open procedure and all patients were very satisfied with the appearance of their scars.
Conclusions: LESS-RN can be performed safely in high risk patients.
