膀胱頚部硬化症におけるレ線学的診断法

Abstract

An investigation was made on the diagnostic significance of Yanase's method of roentgenological visualization of the vesical neck in 25 patients with bladder neck sclerosis who had been operated in the past ten years. Attention must be directed to the contracture localized at the internal orifice and the contracture in the posterior urethra. Differential diagnosis between minute type of benign prostatic hypertrophy and bladder neck sclerosis was difficult in this method. But this urethrographic sign is offered as an aid to the preoperative diagnosis of bladder neck sclerosis.
