男子尿道狭窄症に対する内尿道切開術の経験

Abstract

Many urologists have had prejudices against internal urethrotomy without good reason. Only a small number of patients with urethral stricture has been treated in Japan by internal urethrotomy. Twelve cases of urethral stricture were treated by internal urethrotomy and were followed up from two to eighteen months. Maisonneuve urethrotome was used in combination with catheterization for three weeks to maintain separation of the cut surfaces while epithelialization took place. Complications have been minimal and our results are gratifying. In five cases, urethra has been excellently repaired by only a single procedure. In other five cases, urethra had appeared as wide as healthy one just after the procedure, but a few months later urethrogram revealed an inconsiderable stricture without any complaints. In the remaining two patients, who had recieved regular interval dilatation over a long term, the procedure was proved to be rather ineffective. From our experiences, we believe that internal urethrotomy is a valuable procedure for male urethral stricture, which should be used more widely and it would seem advisable to need much deeper incision for stricture extending over a wide area of the anterior urethra.
