The urethral pressure profile (UPP) was studied in both normal and pathological conditions. The technique used was that of Brown and Wickham. The examined five groups of patients were normal adult females (40 cases), normal adult males (12 cases), patients of bladder neck contracture (15 cases), patients of benign prostatic hypertrophy (27 cases), and patients of neurogenic bladder after radical total hysterectomy (49 cases).
Analysis of the five groups showed the following results
1. In the normal adult females, a progressive fall of the maximum closure pressure with age was found.
2. In the patients of bladder neck contracture, its UPP was the same as that of normal adult male and it was thought that the UPP had little diagnostic value for bladder neck contracture.
3. In the patients of benign prostatic hypertrophys, the functional profile length and the prostatic profile length were significantly elongated. At the postoperative recording, these lengths were shortened. Its UPP was expected to be useful for screening examination.
4. In the patients of neurogenic bladder after radical total hysterectomy, the maximum closure pressure was significantly failed postoperatively. Its fall was more prominent at the full bladder than at the empty bladder. Its fall was significant in the group with poor micturition pattern on the uroflowmetry. From these results of ours and the review of literature it was presumed that the postoperative fall and postoperative micturition disturbances were due to the operative damage of sympathetic nerves.
