在嚴重或復發性癌症病患中，有時候會遇到必須同時接受尿路及腸道分流手術的情形，對泌尿科醫師而言，治療這些病患困難度高且複雜，對於分流手術的選擇仍然莫衷一是。六位病患在本院接受雙柱濕性大腸造口手術以為尿路及腸道分流，包括五位復發性子宮頸癌合併直腸膀胱陰道廔管患者、一位侵犯性大腸癌患者，追蹤時間約為五至十三個月。兩位患者因手術併發症死亡，一位於術後一個月因大量陰道出血而受動脈栓塞術，手術死亡率約百分之三十，平均存活率約為七個月，此手術之併發症及病患之選擇應於術前作詳細且小心之評估。

Urinary and fecal diversion sometimes happen in patients with an advanced primary or recurrent carcinoma. Most of these cases are tuff and pose complicate problems for urologists, and the choice of diversion is controversial. To date 6 patients have undergone double-barrelled wet colostomy in our section for simultaneous diversion of the urinary and fecal streams with a single abdominal stoma and been followed up from 5 to 13 months. Five cases have recurrent cervix cancer with rectovesicovaginal fistula and one has invasive colon cancer. Two patients had died from complications of the procedure with urosepsis in one case and anastomosis dehiscence in the other one. One patient had massive vaginal bleeding one month after the surgery and received arterial embolization. The other three had more satisfactory results with fair conditions. The perioperative mortality rate is 33% and mean survival time is about 7 months. The risk of complication and selection of patient should be carefully evaluated before carrying out this procedure.
