The safety of surgical treatment for complex renal calculi

Abstract

Objective To explore the safety of surgical treatment for complex renal calculi.Methods 30 patients with complex renal calculi who had been treated during the period of March 2001 to September 2012 were included in this study.15 patients underwent pyelolithotomy,7 received renal parenchyma incision for removing stones,5 received renal sinus parenchyma incision for stone removal,and 3 received renal pedicle vascular blocking plus renal parenchyma incision for removing stones under pararenal low temperature with ice.The efficacy of the procedures,surgical duration,postoperative bleeding volume and duration of hematuria were analyzed.The safety of the procedures were assessed.Results The procedures were successfully perfromed on all patients,and kidney function returned to normal one week after surgery.No patients needed to receive blood transfusion.Residual stones occurred in five patients,with a rate of 16.67％.There were 5 residual stones with a diameter of 0.3 cm to 0.5 cm and they were small calyceal stones,which were finally treated by EWSL.The surgical duration was 50-120 min,with an average of (93 ± 17) min; postoperative bleeding was 50 to 200 ml,with an average of (112 ± 36) ml; and postoperative duration of hematuria was 12 to 48 h,with an average of (28 ± 7) h.Conclusions Surgical treatment for complex renal calculi has higher safety.In clinical treatment,different surgical procedures should be selected accroding to the location and size of the stones.
