目的：观察大网膜包裹修复重度肾损伤的疗效。方法：１７例Ⅳ级肾损伤分成２组：（１）１０例行肾修补后取带蒂大网膜一块包裹伤肾（简称大网膜组）。（２）７例行单纯肾修补（简称单修组）作对照。结果：术后（１）大网膜组在肉眼血尿持续时间、伤口渗液量、伤肾愈合时间均比单修组短和少（Ｐ＜０．０１）；（２）单修组出现伤口渗尿感染１例，而大网膜组无１例并发症发生；（３）随访１ａ，ＩＶＰ检查示大网膜组肾功能恢复良好，而单修组肾功能差（Ｐ＜０．０１）。结论：大网膜是重度肾损伤良好的修复材料。
Objective: To observe the effect of omentum wrapping in the treatment of severe renal injury. Methods: 17 cases of grade Ⅳ renal injury were divided into two groups: (1) 10 cases of renal pedicle were taken from the sutured omentum and injured kidney (referred to as the omental group). (2) 7 cases of simple renal repair (referred to as single repair group) as a control. Results: After operation (1), the duration of gross hematuria, wound exudation and wound healing time were both shorter and less in the omental group (P <0.01); (2) (3) Follow-up of 1a and IVP showed that the renal function in the omental group recovered well, while the mono-repair group had poor renal function (P <0.01) . Conclusion: Omental is a good repair material for severe renal injury.
