MANAGEMENT OF THE URETHRA AND BLADDER Urological injury occurs in about 10 per cent of patients with pelvic ring fractures. As these patients are often seriously ill from other injuries, a urinary catheter may be required to monitor urinary output, and therefore the urologist is placed under pressure to make a rapid diagnosis of urethral damage. There is no place for passing a diagnostic catheter as this will most probably convert any partial tear to a complete tear. For an incomplete tear, the insertion of a suprapubic catheter as a formal procedure is all that is required. Around half of all incomplete tears will heal and require little long-term management. The treatment of a complete urethral tear is controversial. Primary realignment of the urethra may be achieved by performing suprapubic cystostomy, evacuating the pelvic haematoma and then threading a catheter across the injury to drain the bladder. If the bladder is floating high it is repositioned and held down by a sling suture passed through the lower anterior part of the prostatic capsule, through the perineum on either side of the bulbar urethra and anchored to the thighs by elastic bands. An alternative – and much simpler – approach is to perform the cystostomy as soon as possible, making no attempt to drain the pelvis or dissect the urethra, and to deal with the resulting stricture 4–6 months later. The latter method is contraindicated if there is severe prostatic dislocation or severe tears of the rectum or bladder neck.With both methods there is a significant incidence of late stricture formation, incontinence and impotence. ---from 《Apley’s System of Orthopaedics and Fractures》 重点词汇整理： Urological /juərə'lɔdʒikəl/adj. 泌尿道的；泌尿科学的 catheter /ˈkæθətər/n.
