Safety and Efficacy of Simultaneous Bilateral Percutaneous Nephrolithotomy

Abstract

A retrospective review was conducted to evaluate intraoperative and patient outcomes following simultaneous bilateral percutaneous nephrolithotomy (SB-PCNL). Target stone characteristics, operative time, hospitalization length, post-operative complications, blood loss, opioid use, pain, and stone-free rates were evaluated. In total, 42 patients with large renal stones (>20 mm2) were identified for this study, and 38% of them achieved stone-free status with no residual fragments apparent on post-operative day one CT imaging. The maximum mean residual fragment size was 3.67 mm2 and average number of residual fragments following the procedures was 1.63. The rates of blood loss, post-operative complications, opioid use, and pain from the study cohort were similar to the reported outcomes of studies conducted by others. The potential benefits of a single procedure and anesthesia to treat bilateral stone burdens, lower total pain medication prescribed, and lower hospital costs render SB-PCNL as an attractive option in the treatment of bilateral kidney stones.
