By Utilizing Double J Tube Continuous Reflux Perfusion of Bladder to Implement Percutaneous Nephrolithotomy for Renal Calculus without Hydronephrosis

Objective To observe the therapeutic effect of treatment by utilizing double J tube continuous reflux perfusion of bladder to perform percutaneous nephrolithotomy in the treatment of renal calculi without hydronephrosis.Methods 25 renal calculi patients without obvious hydronephrosis admitted to our hospital from September 2010 to May 2011 were selected to perform continuous perfusion of bladder through double J tube to form artificial hydronephrosis.Percutaneous nephrolithotomy was performed afterward.Results 25 cases were successfully established percutaneous minimally invasive channel.23 patients were given single stone crushing,2 cases were given indwelling fistula to perform secondary gravel stone due to hemorrhage and orthostatic intolerance.There were no residual stones among the 20 patients who were given first-stage operation;there were no residual stones among the 2 patients who were given secondary PCNL.ESWL was used to treat the 3 patients who had residual stones.The one-stage stone clearance rate was 80%(20/25).Conclusion By utilizing double J tube continuous reflux perfusion of bladder to implement percutaneous nephrolithotomy for renal calculus without hydronephrosis is safe and effective,and can be promoted clinically.
