目的　探讨手术 +间断性腹膜透析在严重梗阻性肾衰治疗中的作用。方法　严重梗阻性肾衰2 5例 ,急诊一期手术 +间断性腹膜透析 ,术后监测BUN、Cr及尿量改变。结果　 2 5例严重梗阻性肾衰中 18例BUN、Cr术后 2周恢复正常 ,6例BUN、Cr约正常值 2倍 ,1例死于MOSF。结论　对于严重的梗阻性肾衰 ,急诊手术 +间断腹透可明显提高救治的成功率。 Objective To investigate the role of surgery + intermittent peritoneal dialysis in the treatment of severe obstructive renal failure. Methods Serious obstructive renal failure in 25 cases, emergency surgery + intermittent peritoneal dialysis, postoperative monitoring of BUN, Cr and urine output changes. Results Among the 25 cases of severe obstructive renal failure, 18 cases of BUN and Cr returned to normal after 2 weeks of operation, 6 cases of BUN and Cr were about 2 times normal and 1 case died of MOSF. Conclusion For severe obstructive renal failure, emergency surgery + intermittent peritoneal dialysis can significantly improve the success rate of treatment.
