Varying opinions are held as to the usefulness of the retained catheter after perineal operations upon the posterior urethra. Most authorities, in discussing external urethrotomy, pass the retention catheter without comment, advocating the use of the short perineal drainage-tube only. By some it is advised that continual catheterization be employed for twenty-four or forty-eight hours, and that at the end of that time intermittent catheterization be begun. A few favor retention of the catheter for a longer period, varying from three to six days. By no writer with whose counsels I am familiar are we taught to leave the catheter in after perineal urethrotomy until the urethral and perineal wounds are firmly healed.
Permanent catheterization for a period as long as twenty days is common practice in hematuria, having its origin in trauma of the prostate, and, as is well known, it is often indicated and employed in certain cases
