Purpose. A comparative assessment of health-related quality of life in patients undergoing simultaneous bilateral and staged bilateral mini-percutaneous nephrolithotomy was conducted, and factors affecting the quality of life of patients were investigated.

Materials and methods. A prospective analysis of health-related quality of life of 79 patients who underwent a simultaneous and staged bilateral mini-percutaneous nephrolithotomy was performed. Quality of life was investigated using the SF-36 questionnaire before surgery, 10 days aer surgery, 1 month and 6 months aer surgery. During 3 days after the surgery, the intensity of the pain syndrome was assessed using a visual analogue scale.

Results. In the early postoperative period, patients in the main group had significantly higher scores in terms of social functioning (69.7 ± 12.3 vs. 60.1 ± 10.8 points; p<0.005), role- emotional functioning (67.6 ± 14, 7 vs. 59.4 ± 21.4 points; p<0.005) and mental health (69.4 ± 12.4 vs. 60.1 ± 14.7 points; p<0.005). Physical component summary between the two study groups did not have significant differences during all stages of the survey. Mental component summary in the early postoperative period in the main group were significantly higher in the main group (60.3 ± 10.1 vs. 53.1 ± 11, 3 points; p<0.005).After 6 months aersurgery, patients in both groups reported a comparable improvement in all indicators of health-related quality of life.

Conclusions. Despite the absence of differences in the efficiency of fragmentation of stones, the quality of life of patients aer simultaneous surgical procedures in the early postoperative period was relatively high due to the shorter duration of hospitalization and early rehabilitation of patients
