Explore the major channel of percutaneous renal fistula for treatment of complex renal calculi

【 Objective】To investigate the passage of percutaneous renal fistula method of treatment of complex renal calculi and its advantages.【Methods】102 cases of kidney-shaped stone,or cast a huge kidney stone patients were randomly divided into two groups,each of 51 cases,respectively,the major channel by percutaneous renal fistula lithotripsy and percutaneous renal micro-fistula lithotomy (MPCNL).【Results】The major channel of percutaneous renal fistula lithotomy mean operative time was 72 min,blood loss of about 110 mL,to take the net rate of 90% of the stones,two stones to take the net rate of 98%,intraoperative and postoperative bleeding or line does not appear super-selective renal embolization.Percutaneous renal micro-fistula lithotomy were operating time was 150 min,blood loss of about 105 mL,to take the net rate of 80% of the stones,two stones to take the net rate of 90%,intraoperative and postoperative bleeding does not occur or line of super-selective renal embolization.【Conclusion】 Percutaneous nephrolithotomy channel treatment of complex renal calculi reduce surgical time and improve the stone to take the net rate,without increasing the risk of injury and bleeding.
