直肠癌Miles术保留盆腔自主神经对排尿功能的影响

目的探讨直肠癌Miles术中保留盆腔自主神经（PANP）对术后排尿功能的影响。方法行PANP＋Miles术的直肠癌患者56例为观察组,行传统Miles术的直肠癌患者56例为对照组,对2组患者术后排尿功能障碍的情况进行回顾性分析。结果术后3d,对照组均未拔除尿管,而观察组36例（64.3%）拔除尿管,且均能自主排尿,其中10例有轻度排尿困难。术后7d,2组患者均拔除尿管,观察组10例（17.8%）出现排尿困难,对照组35例（62.5%）出现排尿困难,19例（33.9%）出现尿潴留。术后15d,观察组基本恢复正常排尿,对照组27例（48.2%）有排尿功能障碍。2组差异有统计学意义（P〈0.05）。结论PANP可以明显减少Miles术后患者排尿困难的发生率。

Influence of pelvic autonomic nerve preservation on urinary function in Miles operation for rectal cancer

Objective To analyse the influence of pelvie autonomic nerve preservation （PANP） on urinary function in Miles operation for rectal cancer. Methods To retrospectively analyse urinary disfunction rate in the two groups of 112 rectal carcinoma patients who underxwent traditional or PANP radicul operation respeetivery. Results 3 days after operation, in traditional group 56 cases were not removed cartheter,while in PANP 64.3% were removed cartheter,and they all can urinate independently, 10 cases have slight urination dysfunction. 7 days after operation, both group were removed eartheter, 17.8% in PANP group showed urination disfunetion ,while 62.5% in traditional group showed urination disfunction, 19 cases showed urine retention, 15days after operation, PANP group all recovered, while in traditional group 48.2% still have urination disfunction. The difference between them was significant （ P 〈 0.05 ） Conclusion PANP can reduce the urinary disfunction rate in Miles operation for rectal cancer.
