چکیده

BACKGROUND A previous study showed that foot stimulation can delay the bladder filling sensation and increase bladder volume in healthy humans without OAB. The aim of this study was to determine whether or not electrical stimulation of somatic afferent nerves in the foot can increase bladder capacity in neurogenic bladder patients after sigmoid cystoplasty. METHODS Eleven subjects underwent 30-min foot stimulation using skin surface electrodes connected to a bladder-pelvic stimulator. The electrodes were attached to the bottom of the foot. The subjects completed a 5-day voiding diary, during which time foot stimulation was applied on day 3. The stimulation parameter was a continuous, bi-polar square wave form with a pulse duration of 200 μs and a stimulation frequency of 5 Hz. The stimulation intensity was set by each subject at a maximal level without causing discomfort. RESULTS The volume per clean intermittent catheterization (CIC) was 279.4 ± 11.7 ml and 285.4 ± 11.8 ml on the 1st and 2nd days, respectively. On the 3rd day, the average volume per CIC increased to 361.1 ± 18.1 ml after stimulation (p <0.05). The average volume per CIC returned to 295.4 ± 13.4 ml and 275.1 ± 11.5 ml on the 4th and 5th days, respectively. CONCLUSIONS Foot stimulation can delay the bladder filling sensation and significantly increase bladder capacity in neurogenic bladder patients after sigmoid cystoplasty.

Transcutaneous electrical stimulation of somatic afferent nerves in the foot relieved symptoms related to postoperative bladder spasms

BACKGROUND Bladder spasm is a common side effect of urological surgery. Main treatment modalities include opioids or anticholinergic medication; however, bladder spasms still occur even after these interventions. Recent studies indicate that transcutaneous stimulation of the foot can result in 50% increase in bladder capacity in healthy adults, and inhibit bladder detrusor overactivity in spina...

Augmentation Cystoplasty: in Pretransplant Recepients

Augmentation cystoplasty is performed to increase bladder capacity and compliance. The primary use of augmentation cystoplasty is to protect renal function, to achieve urinary continence, and often to facilitate urinary tract reconstruction (1). The most common problems necessitating bladder augmentation are neurogenic bladder dysfunction secondary to myelodysplasia, extrophy of the bladder, an...

Semiconditional Electrical Stimulation of Pudendal Nerve Afferents Stimulation to Manage Neurogenic Detrusor Overactivity in Patients with Spinal Cord Injury

OBJECTIVE To evaluate the effect of semiconditional electrical stimulation of the pudendal nerve afferents for the neurogenic detrusor overactivity in patients with spinal cord injury. Forty patients (36 males, 4 males) with spinal cord injury who had urinary incontinence and frequency, as well as felt bladder contraction with bladder filling sense or autonomic dysreflexic symptom participated ...

Aging impairs neurogenic contraction in guinea pig urinary bladder: role of oxidative stress and melatonin.

The incidence of urinary bladder disturbances increases with age, and free radical accumulation has been proposed as a causal factor. Here we investigated the association between changes in bladder neuromuscular function and oxidative stress in aging and the possible benefits of melatonin treatment. Neuromuscular function was assessed by electrical field stimulation (EFS) of isolated guinea pig...
