Efficacy and Safety of Ultrasound-guided Percutaneous Nephrolithotomy in Flank position

Abstract

Objective: To evaluate the efficacy of clinical result and safety of ultrasound-guided Percutaneous Nephrolithotomy (PCNL) in Flank position. Material and methods : A total of 142 renal stones patients undergone ultrasound-guided PCNL in Flank position between January 2015- December 2017 in Buriram hospital, were prospectively observed. Stone size, operative time and length of stay were recorded. Stone free rate, blood transfusion and postoperative complications were evaluated. Results: The collecting system could be successfully approached in 142 patients (97.9%). Stone free rate was 81.3%. The mean length of stay was 6.3 days. The mean total operative time was 78.1 minutes. Six patients needed blood transfusion. Postoperative urinary tract infection was found 7 cases, 1 case was presented with septic shock. Minor tear of renal pelvis was found 3 cases. The pleural or visceral organ injury was not found in this study. Conclusions: Ultrasound-guided PCNL in Flank position provided satisfactory result. Its efficacy and safety were comparable to standard PCNL. The operative teams were radiation-free exposed in this technique.
