Treating Complex Upper Urinary Calculi With Different Type of Channel of Percutaneous Renal Fistula

［Abstract］Objective　To compare the clinical result of different type of channel of percutaneous renal fistula in treatment of complex upper urinary calculi．Methods　32 patients accepted the operation with 16 F channel of percutaneous renal fistula，and 20 patients with 20 F channel．After the channel was made，the litholapaxy was performed with the help of Holmium Laser．The clean rate of the stone in one-stage operation，average time of the operation，the postoperative decreasing level of hemoglobin and the rate of blood transfusion were compared between these 2 groups．Results　The clean rate of the stone in one-stage operation of the 16F group was 47%（15/32）， and to the 20F group，it was 65%（13/20），the difference was insignificant（P＞0.05）；the average time of operation of 16F group was 2.3±0.6 hours，and it was 1.5±0.5 hours in 20 F group，the difference was significant（P＜0.05）； the postoperative decreasing level of hemoglobin of 16 F group was 16±7.5 g/L，and it was 18±8.5 g/L in 20 F group， and the difference was insignificant（P＞0.05）；the rate of blood transfusion of 16F group was 6%（2/32）， and it was 10%（2/20）to 20 F group，the difference was insignificant（P＞0.05）．Conclusion　In the treatment of complex upper urinary calculi， when compared with 16F channel of percutaneous renal fistula， 20 F channel is more effective，rapid and safe，so this channel deserves to be used in clinical works
