Objective: The objective of this study was to evaluate the safety profile and efficacy of “flank-free modified supine position (FFMS)” approach for percutaneous nephrolithotomy (PCNL). Materials and methods: This study was conducted in the Department of General Surgery over 4-year period from August 2016 to August 2020 on 50 patients after institutional ethical clearance. Results: The patients in our study were in the range of 21–65 years with mean age of 35.9 SD 9.85 years. Approximately, 62% of patients were males and right kidney was involved in 54%. The mean stone size of our study group was 17.3 SD 1.81 mm with a range of 14.2–21 mm. Pelvic stones were found in 28 (56%) of patients and majority of our patients, i.e., 88% were symptomatic of their disease. The mean operative time in our study was 83.62 SD 16.95 with range of 60–115 minutes. Nephrostomy was placed in situ in 84% patients. There was no operation related mortality in our study. The mean hospital stay of our patients was 3.7 SD 1.15 days. Out of total 50 patients, success was achieved in 45 (90%) patients as 6% required auxiliary treatment and 4% was converted to prone position. Conclusion: Thus, in our study we found that FFMS PCNL surgery is a safe and an effective means of intrarenal access with high success rate and with acceptable morbidity and complications.
