摘要:

Under standardized conditions, simultaneous urethrocystometry and recording of urethral pressure profile were performed in 10 healthy volunteers and 20 patients suffering from urge incontinence. In the normal subjects, desire to void occurred at a bladder volume of about 300 cm3. At maximum bladder capacity (∼ 500 cm3), variations in intraurethral pressure were recorded at a time when the intravesical pressure remained stable. Immediately before voiding, there was a marked reduction in intraurethral pressure and then the intravesical pressure increased. In 10 of the patients with symptoms of urge incontinence, the findings did not differ from those in the normal subjects. In the other 10 patients, urgency was reported at bladder volumes between 125 and 150 cm3, and the maximum bladder capacity did not exceed 200 cm3. In 8 of them, marked variations in intraurethral pressure were recorded when urge was experienced, whereas the bladder pressure remained stable. In 2 of the patients, variations in intraurethral and intravesical pressure occurred simultaneously. The role of the urethra in urge incontinence is discusse

摘要:

The evolution of patterns of neurogenic vesical dysfunction with emphasis on urethral resistance has been studied using a two-catheter urethral profile technique in 24 patients following acute spinal cord injury. Inappropriate urethral resistance to voiding appeared to result both from smooth and skeletal muscular activity and to some extent was dependent on the level of the spinal cord lesion. Autonomic dysreflexia was common, and responded to treatment with an α-sympatholytic agent

摘要:

Prolonged bladder distension has been used to treat patients with urgency and urge incontinence of urine. At follow-up varying from 14 to 24 months 17 out of 33 patients were symptom-free, 13 symptomatically improved and 3 unchanged. These results, as anticipated, are not so good as the initial early reported results, but are sufficiently encouraging for us to recommend prolonged bladder distension for the treatment of severe urgency and urge incontinence of urine.

摘要:

Eleven patients with incontinence of urine owing to detrusor contractions have been treated by partial denervation of the bladder. Seven have substantially improved.

摘要:

In a retrospective study of 579 patients with cystometrically proven detrusor hyperreflexia bacteriuria was correlated to the commonly accepted etiologies, and to the duration and amplitude of the uninhibited bladder contractions. Blood flow in the bladder wall may be reduced by increased intravesical pressure due to detrusor hyperreflexia, and it has been suggested that a resulting weakening of antibacterial defense mechanisms is responsible for the majority of urinary tract infections in these patients. We have not been able to confirm this hypothesis. We found no statistically significant difference between the incidence of bacteriuria in patients with low amplitude and short duration of the bladder contractions and in patients with high amplitude and long duration of the uninhibited bladder contractions.

摘要:

Using sophisticated recording equipment and two fine copper wire electrodes introduced through the cystoscope into the bladder muscle of conscious patients at cystoscopy, reproducible electromyographic recordings were obtained from the normal and the neuropathic bladders of a group of patients. By means of simultaneous recording of the electromyographic activity of the rectus abdominis muscle in these patients, it was found that, in general, the variations in electromyographic activity of the normal bladder with filling and voiding are quite independent of abdominal muscle activity. The upper motor neuron bladders by a way of contrast showed continuing electrical activity even at rest and this activity increases with abdominal contraction. Lower motor neuron bladders remain electrically silent at all times including during abdominal muscle contraction. This suggests that the bladder electrodes do not record remote muscle activity from the abdomen or elsewhere and confirms the validity of the detrusor EMG.

摘要:

A new standardized technique for continuous recording of the urethral pressure profile simultaneously with intravesical pressure has been developed. The pressures are recorded using two microtransducers enclosed in a thin Dacron catheter. The catheter is moved at a constant speed through the urethra with the aid of a specially designed withdrawal instrument. Using electronic subtraction the closure pressure can easily be measured simultaneously with the intravesical and intraurethral pressure. About 900 investigations have been performed with this technique. It has been testified that very detailed information about normal micturition as well as stress and urgency incontinence can be obtained. The functional as well as the absolute length of the urethra can be estimated within half a millimeter.

摘要:

The shape of the urethral closure pressure profile of 281 male patients has been analysed. ‘Prostatic’ length, ‘prostatic’ peak, ‘prostatic’ plateau height and ‘prostatic’ plateau area have been measured. This study has shown that these parameters have a significant relation to the diagnosis of bladder outflow obstruction made after uro
