Phần lớn các thương tích như vậy có thể được quản lý bởi một khoảng thời gian dẫn dòng nước tiểu suprapubic, mà không cần phải phẫu thuật tiếp theo. Sẽ chữa lành mà không có một hẹp đáng kể chức năng (Cass và Godec năm 1978, Pierce 1989), sau khi một vài tuần thoát nước. | 112 J. REYNARD thral contusion. If there is extravasation of contrast with contrast also present in the bladder the patient has a partial rupture of the anterior urethra. If there is no filling of the posterior urethra or bladder the anterior urethral disruption is complete. Management of Anterior Urethral Injuries Anterior Urethral Contusion A small-gauge urethral catheter 12 Ch in an adult is passed. It is removed a week or so later. Partial Rupture of Anterior Urethra The majority of such injuries can be managed by a period of suprapubic urinary diversion without the need for subsequent surgery. Most will heal without a functionally significant stricture Cass and Godec 1978 Pierce 1989 after a few weeks of drainage. If there is a penetrating partial anterior urethral disruption . knife gunshot wound primary immediate repair may be carried out but this depends on the presence of a surgeon experienced in these techniques. There is some evidence that the stricture rate with immediate surgical repair is lower than that associated with realignment of the urethra by urethral catheterisation alone Husmann et al. 1993 . Suprapubic catheterisation percutaneously is preferred over urethral catheterisation because of the concern that a partial rupture can be converted to a complete rupture. If the bladder cannot easily be palpated such that a suprapubic catheter cannot safely be inserted then a formal open suprapubic cystostomy under general anaesthetic should be performed. It seems a sensible idea to give these patients a course of a broad-spectrum antibiotic to prevent infection of extravasated urine and blood. A voiding cystogram can be done after 2 weeks to confirm that the urethra has healed and the suprapubic catheter can then be removed. If there is still extravasation of contrast the suprapubic catheter can be left in place a little longer. Seventy percent or more of partial urethral tears heal without stricture formation following a short period of suprapubic .
