| Objective: To compare the efficacy and advantages of standard percutaneous nephrolithotomy(PCNL) and mini-percutaneous nephrolithotomy(mPCNL) in the treatment of renal calculi, improve the treatment of kidney stones. Methods: From Oct. 2012 to Oct. 2014, application of B-guided PCNL was performed in 150 patients and mPCNL in 150 patients. Statistics the stone-free rate and effcts on renal function. Results: 18 F and 24 F percutaneous renal access were successfully established in PCNL and mPCNL group respectively. The PCNL group had a shorter operation time than the mPCNL group. The one-stage stone-free rate for multiple stones was significantly higher in the mPCNL group than in the PCNL group. However, the rate for simple renal pelvis stone was significantly lower in the mPCNL group than in the PCNL group. There was no statistical difference in the one-stage stone-free rate for staghorn stone, complications rate, blood transfusion, and postoperative hospital stay between the two groups. The blood loss in mPCNL was less than in PCNL group, but the rate of blood transfusion and the remaining was no significant difference. Conclusion: The PCNL may be suitable for large renal stone, while mPCNL may has advantages in the treatment for renal calyx stone. |
