摘要:
目的 探讨微通道经皮肾镜碎石取石术(mPCNL)与标准通道经皮肾镜碎石取石术(标准通道PCNL)治疗肾结石的有效性及优缺点,提高肾结石的治疗水平。方法 2009年1月-2012年7月,应用B超引导下mPCNL与标准通道PCNL分别治疗178例和194例肾结石。统计结石清除率及对肾功能的影响等。结果 mPCNL组与标准通道PCNL组一期分别建立F18和F24肾穿刺通道。标准通道PCNL组手术时间比mPCNL组缩短(P<0.05);单纯肾盂结石一期清除率高于mPCNL组(P<0.05);而mPCNL组对肾盏多发性结石患者一期结石清除率高于标准通道PCNL组(P<0.05)。mPCNL组术中出血量明显少于标准通道PCNL组(P<0.05),但输血率及留管时间差异无统计学意义(P>0.05)。两组患者术后第1天、第3天及1个月的血肌酐Cr较术前有所升高,mPCNL组较标准通道PCNL组变化更大(P<0.05);肾小球滤过率GFR在术后第1天出现一过性的下降,mPCNL组比标准通道PCNL组下降更大(P<0.05),3天后基本恢复正常。结论 较大的肾盂结石优选标准通道PCNL,肾盏多发结石首选考虑用mPCNL处理。标准通道PCNL对患者肾功能的影响要小于mPCNL。建立通道扩张所引起的肾功能的损害要小于灌注压力的危害。
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 Jan. 2009 to July 2012, application of B-guided PCNL was performed in 194 patients and mPCNL in 178 patients. Statistics the stone-free rate and effcts on renal function. Results: 18F and 24F 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, renal function, 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. First and third days and one month, the Cr was more in both group, and greater in mPCNL. GFR had dedined in the first day and greater in mPCNL, and three day later the GFR retuned to normoal. Conclusion: The PCNL may be suitable for large renal stone, while mPCNL may has advantages in the treatment for renal calyx stone. PCNL is less than mPCNL on renal function. Renal function impairment caused by expansion in the establishment of channel process is far lower than caused by the perfusion pressure.
