Advance in research of treatment and prognosis of iatrogenic rectourethral fistula.

Recturethral fistula (RUF) is a kind of serious complication that mainly happened during the treatment of prostate cancer. It has become one of the most difficult diseases to treat in urology because of its special anatomical location, complicated condition, and the varied prognosis. At present, the main treatment methods for RUF are conservative treatment such as application of antibiotics and indwelling catheters, etc. and surgical treatment such as transperineal approach, transsphincter approach, transanal approach, transabdominal approach, etc. However, there is no explicit treatment protocol for RUF. What's more, the etiology of RUF has changed greatly in recent years. Summarizing the advantages and disadvantages of different RUF's treatment methods and their prognosis will be helpful for the decision of clinical treatment.
