The Clinical Research Of Utilizing Of The Foley Catheter Strained For Hemorrhage Of Post-microchannel Percutaneous Nephrolithotomy

Objective:Renal hemorrhage is one of the most common and worrisome complications of post-percutaneous nephrolithotomy.This study aimed at evaluating the safety,effectiveness,and feasibility of utilization of the Foley catheter strained for hemorrhage of post-microchannel Percuta-neous Nephrolithotomy.Methods:88 Patients were collected prospectively at urology department of CSU XIANGYA Hospital during november 2010 to June 2011 with upper urinary calculi undergoing mPCNL procedures,and divided into two groups randomly.one group(45patients) with 16F Foley catheter unstrained as nephrostomy,another group (43patients) with 16F Foley catheter strained. Blood loss was estimated based on the the mass of hemoglobin in the draining liquid and urine during postoperative duration through the HiCN.Blood loss and bleeding time were compared in 2 groups with Wilcoxon rank sum test.RESULTS:The average blood loss was 13.82638g and 7.957g (P<.001). The mean bleeding time was 4 and 3days (P<.002), A statistically significant difference was found. CONCLUSIONS:Utilizing the Foley catheter strained for hemorrhage of post-microchannel Percutaneous Nephrolithotomy is a safe,effective and feasible method.
