Flank suspended supine position versus standard supine and prone positions in percutaneous nephrolithotomy

Background and aim The aim of this article was to compare the outcome of percutaneous nephrolithotomy (PCNL) in flank suspended supine position (FSSP), standard prone position, and standard supine position. Patients and methods This study was conducted on 60 patients with renal stone disease from March 2013 to October 2016 in the Department of Urology, Benha University Hospital, and they were divided randomly into three groups: group A had 20 patients who underwent PCNL in FSSP, group B had 20 patients who underwent PCNL in standard supine position, and group C had 20 patients who underwent PCNL in prone position. Results A total of 60 patients were divided into three groups − A, B, and C − with 20 patients in each group. Mean age in group A was 30.05±14.93 years, in group B was 49.35±14.31 years, whereas in group C was 35.15±15.18 years. The mean BMI by kg/m2 in group A was 25.81±6.16, in group B was 27.68±6.74, and in group C was 30.94±6.65. There were 38 males and 22 females who were divided into three groups: group A had 11 (55%) males and nine (45%) females, group B, had 10 (60%) males and 10 (40%) females, whereas group C had 13 (75%) males and seven (25%) females. There were 33 right renal stones and 27 left renal stones, which were divided into three groups. Group A had 11 (65%) right renal stone cases and nine (35%) left renal stones, group B had 13 (70%) right renal stones and seven (30%) left renal stones, whereas group C had nine (45%) right renal stones and 11 (55%) left renal stones. Conclusion In conclusion, PCNL in the FSSP position is safe, effective, and suitable for patients, especially morbidly obese patients; it has several advantages like less operative time because of less patient handling and needing drape only once.
