Abdominal drain use is a common practice after urologic procedures involving urinary tract violation with the intention of externalizing potential urine leaks and preventing urinomas. Drains may alternatively be placed to detect bleeding or bowel injury, prevent hematomas or lymphoceles, or for other reasons equally lacking any evidence showing benefits. In general, the practice of placing abdominal drains in urology is based on dogma and learned habits.

大多数机器人泌尿外科手术不需要引流管

在涉及侵犯尿路的泌尿外科手术后，使用腹腔引流管是一种常见的做法，目的是消除潜在的尿漏并预防尿路瘤。或者，可以放置引流管以检测出血或肠道损伤、预防血肿或淋巴囊肿，或者由于同样缺乏任何证据显示有益的其他原因。一般来说，在泌尿外科放置腹腔引流管的做法是基于教条和习得的习惯。
