[A study of bladder function in benign prostatic hyperplasia].

A study of bladder function was performed on 106 patients with benign prostatic hyperplasia (BPH), 21 of whom had cerebrovascular disease (CVD). The incidence of overactive bladder in 21 patients with CVD was 57% and was significantly higher than the 25% in 86 patients without CVD. The incidence of cases having residual urine of over 100 ml, was in the order of low compliance bladder, overactive bladder and normal bladder. The mean value of maximum voiding pressure in overactive bladder was higher than that in normal bladder. The high pressure was improved after the operation for BPH. Improvement of overactive bladder after the operation was seen in 9 of 13 patients without CVD while in 2 of 6 patients with CVD.

[Clinical effects of distigmine bromide (Ubretid), a cholinesterase inhibitor, on micturition disturbance by benign prostatic hypertrophy--comparative study of distigmine bromide and the combination of distigmine bromide and adrenergic blocker].

We report the results of a comparative study on the clinical efficacy of the single use of distigmine bromide and its combined use with prazosin hydrochloride in the treatment of benign prostatic hypertrophy. The single use and combined use groups were administered 10 mg/day of distigmine bromide and the same with 1 mg/day of prazosin hydrochloride for a period of 8 weeks respectively. In the single administration group, marked improvement was found in one patient (9%), moderate improvement in 4 patients (36.3%), slight improvement in 3 patients (27.2%) and aggravation in 3 patients. In the combined use group, marked improvement was found in one patient (11.0%), moderate improvement in 5 patients (55.5%), and slight improvement in 3 patients (33.3%). No significant differences were found in the improvement rate between the two groups. However, significant improvements were found in both groups for the subjective symptoms of urinary disturbance, diurnal and nocturnal frequency. As a result of the examination of objective findings, a significant decrease in residual urine ratio was also shown in both groups, while significant improvement for average flow and maximum flow rates were found in only the combined use group. In conclusion, distigmine bromide and distigmine bromide+prazosin hydrochloride are considered very useful for the treatment of miturition disturbance due to benign prostatic hypertrophy.

[The relationship between pathological spreading factors and tumor size in 45 patients with renal cell carcinoma].

The relationship between pathological spreading factors (T3,4 V+, N+, M+) and tumor size was studied in 45 patients with renal cell carcinoma during the past 10 years from 1982. The incidence of having one or more factors was 0% for the 17 tumors smaller than 5 cm, but 75% for the 28 tumors over 5 cm. The mean diameter of the tumors having a T, V, N or M factor was significantly larger than that of tumors having no factor (T1,2V0N0M0). These findings suggest that they have a higher tendency of having spreading factors once the tumors have exceeded a certain size.

[Clinical study of voiding disorders in patients with cerebrovascular accidents].

Cystometry and urethral pressure profile were determined in 41 patients (29 males and 12 females) with voiding disorders resulting from cerebrovascular accidents within one year after the episode. By clinical symptoms, they were classified into 3 groups, urge incontinence (14 patients, 34%), pollakisuria (10 patients, 24%) and dysuria (17 patients, 41%). Cystometrogram were classified into 3 types, hyperactive bladder (31 patients, 76%), normal bladder (5 patients, 12%) and hypoactive bladder (5 patients, 12%). All patients in both groups of incontinence and pollakisuria showed hyperactive bladder except one normal bladder, while in the group of dysuria 3 types of cystometrograms were observed. Bladder capacity in incontinence group showed tendency to be smaller than that in dysuria group who had hyperactive bladder. Maximum urethral pressure in incontinence group was significantly lower than that in pollakisuria group and dysuria group who had hyperactive bladder. Ten patients with cerebral cortical lesions (80%) showed hyperactive bladder and 60% of them showed incontinence. In patients with cerebral lesions who had hyperactive bladder, the maximum urethral pressure of patients with incontinence showed tendency to be lower than that of patients with pollakisuria and dysuria. The majority of 7 patients with thalamic lesions showed hyperactive bladder and normal urethral pressure, and had dysuria. Two patients with pontine lesions showed hypoactive bladder. These findings suggested that urge incontinence resulting from cerebrovascular accidents was due not only to hyperactive bladder but also to lower urethral pressure.

[Clinical studies of terodiline hydrochloride and clenbuterol hydrochloride for urinary frequency and incontinence].

The clinical effectiveness and safety of terodiline hydrochloride and clenbuterol hydrochloride were studied on 51 patients with neurogenic bladder, stress incontinence, unstable bladder and others, the chief complaints of which were urinary frequency or urinary incontinence. Overall improvement was graded as marked in 6 patients (11.8%), moderate in 20 patients (39.2%), slight in 11 patients (21.6%), unchanged in 13 patients (25.5%) and aggravated in one. The patients impression was "good" or better in 56.9%. There were a total of 13 cases (25.5%) of adverse reactions, namely, 7 cases of finger tremor, 3 cases of dry mouth and others. These reactions disappeared rapidly after the discontinuance of drug administration. The clinical efficacy in the treatment of subjective symptoms was 71.4% for urinary incontinence, 56.4% for diurnal pollakisuria. The examination of lower urethral functions demonstrated a significant (p less than 0.01) increase in bladder capacity at first desire and maximum desire to void. However, we found no significant increase in urethral clossure pressure. The findings of this study suggest that terodiline hydrochloride and clenbuterol hydrochloride are very useful for the treatment of urinary frequency and incontinence.

[Prophylactic effect of UFT on the recurrence of bladder cancer].

To evaluate the effect of UFT, a mixture of ftorafur and uracil in a ratio of 1:4, in preventing postoperative recurrence of bladder cancer, we performed a randomized controlled study with a non-medication group as control. UFT was given orally 400 mg a day for 6 months. Of 111 patients, 56 were given UFT and 55 were followed up without any medication. The non-recurrence rate in the group treated with UFT was 62.8% after 1 year and 36.3% after 2 years of follow up, and that of the control group was 45.7% and 39.5%, respectively. The rate of non-recurrence in the UFT group was significantly higher (p less than 0.05) than that of the control group during the period of follow up for 2 years. The incidence of side effects was 6.8% in UFT patients. These results indicate the clinical usefulness of prophylactic administration of UFT for bladder cancer patients.

[Primary malignant lymphoma of the urinary bladder: report of a case].

A case of primary malignant lymphoma of the bladder is presented. A 42-year-old woman was admitted to our clinic with the chief complaint of asymptomatic hematuria. Examination of cystoscopy, IVP, ultrasonography and CT scan suggested a non-epithelial tumor of the bladder, which was reported as malignant lymphoma, non-Hodgkin, by findings of transurethral biopsy. Subsequent systemic CT scan, Ga-scintigraphy and bone marrow puncture revealed no abnormalities. Therefore, this case was thought to be primary malignant lymphoma of the bladder. Partial cystectomy with pelvic lymph node resection was carried out. The tumor, 2 x 1 cm in diameter, invaded into the middle portion of muscularis. Histological diagnosis of the tumor was follicular lymphoma, medium-sized cell type according to LSG classification, and immunohistological findings also showed B-cell lymphoma. Resected lymph nodes had no signs of neoplasms. Postoperative adjuvant chemotherapy consisting of vincristine, cyclophosphamide and prednisolone was performed. She has been doing well without any clinical evidence of recurrence for 16 months after the operation.
