Abstract
Objective To investigate the clinical effect of ultrasound guided multi-tract percutaneous nephrolithotomy in the treatment of complex renal calculi. Methods A total of 300 patients in our hospital from January 2013 to December 2016 who underwent ultrasound guided percutaneous nephrolithotomy were retrospectively included in our study. One hundred and fifty patients were in the multi-tract group and the other 150 were in the single channel group. The operation time, estimated blood loss and nephrotomy tube stay time, the stone clearance rate and postoperative complications were compared. Results The basic and preoperative characteristics had no significant difference between the two groups, and the hospital stay time, incision infection and blood loss were similar in the two groups. But the stone clearance rate and nephrotomy tube stay time were significant shorter in ultrasound guided group(P<0.05)while the operation time was longer in multi-tract group. Conclusions The ultrasound guided multi-tract percutaneous nephrolithotomy were effective in treating complex renal calculi than single channel method and thus should be recommended in clinical practice. Key words: Kidney Calculi; Nephrostomy, Percutaneous; Ultrasonography
