Biofeedback in the treatment of detrusor instability.

Detrusor instability has remained resistant to conventional forms of treatment. An attempt to use biofeedback methods in its management is described. Six female patients with symptoms of frequency, urgency and urge incontinence due to detrusor instability were conditioned to auditory and visual stimuli for 6 to 8 1 h sessions. They were assessed clinically and urodynamically. The results are presented as well as detailed case studies of 3 patients. Subjectively, 3 were cured, 2 improved and 1 remained the same; objectively, 3 were cured, 1 improved and 2 remained the same. No significant side effects were encountered.

Idiopathic bladder instability treated by biofeedback.

Biofeedback training has been used to treat 27 female patients suffering from symptoms associated with detrusor instability Re-education to auditory and visual stimuli took place during 4 to 8 one-hour sessions at weekly intervals. Using subjective and objective methods of assessment 81% of the patients were improved following treatment.

Spontaneous voiding after surgery for urinary incontinence.

Eighty patients with urinary incontinence were treated by colposuspension and bladder neck plication. Fourteen patients had difficulty in establishing normal micturition postoperatively. Of these, 10 patients took longer than 21 days to void and had reduced peak urine flow rates after surgery; the other four patients voided within ten days of surgery but had reduced peak urine flow rates before and after surgery and all had residual urines in excess of 100 ml following surgery. The value of the preoperative diagnosis of pre-existent bladder dysfunction by symptomatology and the peak urine flow rate is discussed.

A psychiatric study of women with urgency and urgency incontinence.

26 patients with frequency, urgency and urgency incontinence, without bladder or urethral abnormality, underwent psychiatric evaluation. They were divided into 2 groups according to the degree of neuroticism found. Treatment by group and individual psychotherapy showed that approximately one-third of the patients benefited considerably, one-third refused treatment or ceased prematurely and one-third improved slightly or not at all. The importance of excluding organic bladder or urethral disease prior to psychiatric assessment is stressed.

The colposuspension operation for urinary incontinence.

Forty-two patients with urinary incontinence and related symptoms were treated by colposuspension. Two patients were lost to follow-up and the results of surgery in the remaining 40 patients are presented and discussed. The place of vaginal surgery in women with urinary symptoms is also discussed.

Seminal prostaglandins in infertile men.

The concentration of prostaglandin E (PGE) was measured in the semen of 5 men of proven fertility and in 12 men of couples who were infertile but in whom no abnormality had been detected by conventional semen analysis, postcoital test of sperm motility, endometrial biopsy, and laparoscopic dye insufflation of the fallopian tubes. In the fertile men the mean PGE concentration was 52.7 +/- 9.9 mug/ml, and in infertile men the concentration was 22.1 +/- 2.76 mug/ml; the difference between the two groups was highly significant (P less than 0.001). In five of the infertile men attempts were made to raise the PGE concentration by the administration of either corn oil, which contains the prostaglandin precursor linoleic acid, or caffeine, which inhibits prostaglandin degradation; the response to both agents was insignificant.

Electromyography of the detrusor muscle.

In order to diagnose and treat patients with micturitional disturbances it is necessary to obtain as much information as possible about the function of the lower urinary tract in each case. We studied 70 female patients with micturitional disturbances by monitoring pulse, respiration, intrinsic bladder pressure, urine flow rate and volume, and detrusor and sphincter electromyograms during a 2 to 4-hour period. As earlier investigators have shown, there are 2 types of detrusor electromyograms: low frequency and high frequency activity. The low frequency activity is random in nature and has definite patterns in disturbed bladder function. It is a useful diagnostic parameter and, when considered with the results of the sphincter electromyograms and pressure recordings, it provides much diagnostic information in this group of patients. The high frequency activity is similar to that of striated muscle.

Computer analysis of electromyographic signals from the human bladder and urethral and anal sphincters.

An investigation has been made into the form of the EMG signals from the human bladder and urethral and anal sphincters. A buildup of the low frequency detrusor EMG before micturition occurs in some patients and this is more marked in patients with urgency. A good correlation occurs between the amount of EMG activity and bladder activity as assessed by the cystometrogram. Marked spike activity has been seen in the detrusor EMGs of patients with irritable bladders. The comparison of anal and urethral sphincter EMGs is of interest from the viewpoint of the anatomy of the urethral sphincter and the mechanism of micturition.
