Objective To investigate the therapeutic effect and safety of drainage tubes with different calibers in treating pyonephrosis in percutanous nephrostomy.Methods 42 patients from 2007 to 2010 with pyonephrosis and the symptom of fever underwent anti-infection treatment and percutanous nephrostomy.They were divided into two groups:big drainage tube group and small drainage tube group according to the size of pipe diameters,namely F6 and F16 drainage tube.Results Patients in both groups reported relived lumbago and normal body temperature postoperatively.The operation time,postoperative pain grades,times of applying painkillers,duration of increased temperature and leukocyte levels in the two groups were (21.68 ± 5.38) min,(3.61 ± 2.42) points,(0.72 ± 0.71) times,(2.73 ± 2.47) d,(5.22 ± 1.25) d and (12.70 ± 4.64) min,(2.00 ± 1.92) points,(0.26 ± 0.51) times,(4.82 ± 2.09) d,(7.10 ± 1.74) d respectively.Results of comparison between groups were considered significant (P ＜ 0.05).Conclusion Drainage tubes of both calibers prove safe and effective in treating pyonephrosis in percutanousnephrostomy.Relatively speaking,the small drainage tube technique is easy to operate with shorter operation time and fewer pains after surgery,while better effects are observed in big drainage tube group.%目的 探讨不同管径引流管对经皮肾穿刺造瘘引流肾积脓的疗效和安全性的影响.方法 2007年至2010年我院收治的肾积脓有发热的患者42例,予以抗感染和经皮肾穿刺引流治疗,小引流管组使用F6引流管,大引流管组使用F16引流管.结果 两组术后腰痛缓解,体温降至正常.大引流管组和小引流管组造瘘时间、术后疼痛评分、使用止痛药次数、体温降至正常时间和白细胞降至正常时间分别为(21.68±5.38) min、(3.61±2.42)、(0.72±0.71)、(2.73±2.47)d、(5.22±1.25)d和(12.70±4.64)min、(2.00±1.92)、(0.26±0.51)、(4.82±2.09)d、(7.10±1.74)d.结论 两种管径引流管在经皮肾穿刺造瘘引流肾积脓中都安全、效果确切,小引流管方法操作简单、手术时间短、术后疼痛轻,但大引流管的效果较好.
