X線撮影法による排尿障碍の研究 --排尿時尿道膀胱撮影法-

Abstract

The author and others reported a part of results ab o ut studies of "Physiology and Pathology of Voiding" which was done by application of seriography and cineradiography to voiding cystourethrography. The c onclusions are as follows : 1) In normal cases, descending of the bladder base and opening of the internal meatus were shown. 2) In prostatic hypertrophy where patients could not void spontaneously descending of the bladder base was shown to a slight degree, but using the parasympathomimetic agent, Besacolin, the descent became more clear than before. After prostatectomy the descent of the bladder base and the opening of the internal meatus were clearly shown and urine was completely voided. 3) In p r ostatic cancer, descending of the bladder base and opening of the internal meatus were scarecely shown. The author believes that the above indications as well as the stiffness of the posterior urethra should be a help in differential diagnosis from the prostatic hypertrophy. 4) In neurogenic bladder, descending of the bladder base and opening of the internal meatus were clearly shown. 5) In urethral s t r icture, dilatation of the urethra as far as the strictural portion was shown with hard voiding.
