[The influence on the urinary tract function after modified radical hysterectomy (author's transl)].

Total urodynamics tests, subjective complaints and intravenous pyelographic findings were investigated in order to clarify the condition of urinary tract after modified radical hysterectomy, comparing with radical hysterectomy with complete preservation of the plexus pelvics. The following results were obtained. 1) No subjective complaints of urination were obtained at three months after the operation. 2) The cystometrograms and the urethral profile pressure patterns after the operation were same as the preoperative patterns. 3) The urinary flow curves revealed normal patterns except one case. 4) In I.V.P. findings, considerable transient disturbances were noted on the upper urinary tract in 15.8%. 5) The patients with radical hysterectomy of complete preservation of the plexus pelvics remained direct operative disturbance at three months and from any view points we investigated the radical hysterectomy, even with complete preservation of the plexus pelvics remained worse influence in patients than modified radical hysterectomy.
