[New method of retrograde urethrography. Clinical study of autourethrography].
Autourethrography (A-UG), a new method of retrograde urethrography was developed, in which the patient injects the contrast medium by himself under fluoroscopical observation by urologists out side of the room. For clinical study of A-UG, comparative study between A-UG and the conventional retrograde urethrography (C-UG) was performed on 20 patients with benign prostatic hypertrophy. The mean age was 68.8 years (range 49-85 years) in A-UG and 69.4 years (range 61-86 years) in C-UG. We evaluated complications of A-UG, compared with these of C-UG. Opacification of the posterior urethra was achieved in all but one in A-UG. None of these patients in A-UG experienced pain during the examination of A-UG. On the other hand, all patient experienced pain in C-UG. Urethral bleeding occurred in only one of 19 patients in A-UG, compared with eighteen of 20 patients in C-UG. Extravasation occurred in one of 19 patients in A-UG, compared with three patients of 20 patients in C-UG. A-UG left the urologists free from the radiological exposure. It is concluded that A-UG is highly useful examination for patients and urologists.
