The Clinical Value Of Ultrasound And X-Ray Guided Percutaneous Nephrolithotomy (PCNL) For Treatment Of Kidney Calculi:a Meta-Analysis

Objective:To compare the clinical value of ultrasound and X-ray guided percutaneous nephrolithotomy (PCNL) for treatment of kidney calculi.Methods:We searched relevant clinical controlled articles in Pub Med, EMBASE/Cochrane library and CNKI data base.The outcome in dicators included stone clearance rate, complication rate, puncture time, blood loss, and hospital days. All data were analyzed by Revman 5.0 software.Results:There were 9 articles involved in 1693 patients. The res ults suggested that there was no significant difference in stone clearanc e rate between ultrasound group and X-ray group[OR=1.11,95%CI (0. 83-1.49),p=0.47]. However, the complication [OR=0.43,95%CI (0.27,0. 69), p=0.0004], time to puncture[WMD=-4.54,95%CI (-0.45,-8.62), p= 0.03], blood loss[WMD=-22.77,95%CI (-36.57,-8.97), p=0.001], and h ospital days[WMD=-0.16,95%CI (-0.28,-0.03), p=0.02] is better in ultr asound group than in X-ray group.Conclusions:Ultrasound and X-ray guided PCNL had an equal stone clearance rate, but it seemed that ultrasound was better than X-ra y in time to puncture and hospital days after operation. However, the r esults of this meta-analysis should be treated carefully because of limit ation of data and heterogeneity.
