目的:探讨既往开放取石术、经皮肾镜碎石术和ESWL对微创经皮肾镜碎石术(mini-PCNL)的影响。方法:收集2002年7月～2006年10月收治的885例1156例次接受mini-PCNL术患者的临床资料。将患者分为四组:既往行开放取石术组(A组)、经皮肾镜术组(B组)、单纯ESWL组(C组)、无结石干预史组(D组)。对比分析各组手术时间、结石清除率、出血量、输血率、平均住院日及并发症。结果:各组最终结石清除率未见明显差异(x~2=0.584,P=0.900)。A组的出血量为(10.5±9.3)g/L,明显低于其他各组(F=12.879,P<0.001)。各组手术时间、平均住院日差别无统计学意义(P>0.05)。各组输血率、并发症也未见明显差别。结论:有既往结石干预史的患者行mini-PCNL是安全、有效的。
Objective: To investigate the effect of previous open lithotomy, percutaneous nephrolithotomy and ESWL on mini-percutaneous nephrolithotomy (mini-PCNL). Methods: The clinical data of 885 patients who accepted mini-PCNL in our hospital from July 2002 to October 2006 were collected. The patients were divided into four groups: those who underwent open stone surgery (group A), percutaneous nephrolithotomy (group B), ESWL alone (group C), and no stone intervention group (group D). The operative time, stone removal rate, blood loss, blood transfusion rate, average length of stay and complications in each group were compared. Results: There was no significant difference in final stone clearance (x ~ 2 = 0.584, P = 0.900). The amount of bleeding in group A was (10.5 ± 9.3) g / L, which was significantly lower than those in other groups (F = 12.879, P <0.001). There was no significant difference in the operation time and average length of stay in each group (P> 0.05). Blood transfusion rates in each group, no significant difference in complications. CONCLUSIONS: Mini-PCNL is safe and effective in patients with previous stone intervention.
