OUTCOME ANALYSIS OF PERCUTANEOUS NEPHROLITHOTOMY IN SUPINE POSITION

Abstract

Supine PCNL (Percutaneous Nephrolithotomy) is an Alternative to traditional prone positioning. Benets of the supine position include easy access to the airway and Optimization of cardiopulmonary function in patients. This is a prospective study which analyzes the outcome of percutaneous nephrolithotomy in supine position. There were totally 50 patients included in the study. 27 were male and 23 female patients. Mean age was 43 years, ranging from 18 to 70 years. Right side stones seen in 60% of cases ( 30/50). Average stone size was 2.6cm ranging from 1.8 to 6cm. Average operating time were 63.5 minutes and uroscopy 18.9 minutes (5 to 35 minutes). Clearance rate in our study were pretty good with 90% (45 out of 50 cases). Five patients required secondary procedures and ve had complications in form of sepsis and bleeding requiring blood transfusion. There were no visceral injury or srtula. Thus Supine PCNL has several potential advantages with successful technical feasibility and can be used to treat all stone sizes especially very effective in high risk patients for anesthesia. There is no added risk in this technique, and the stone clearance and complication rates are comparable to standard prone PCNL
