✦ Synopsis
The aim of transurethral electrical bladder stimulation (TEBS) treatment in patients with diminished detrusor contractility is to attain complete voiding, i.e., micturition without residual urine, which is under volitional control. In contrast to other types of electrical bladder stimulation, the physiological basis for this kind of treatment is sensitizing of the bladder mechanoreceptor afferents. The latency of afferent stimuli in normal conditions indicates that myelinated A-&fibers are used for neurotransmission from these mechanoreceptors.
Forty-eight patients with hypocontractile or acontractile detrusor underwent intravesical electrical stimulation. All patients had a history pointing to neurogenic pathology.
Forty patients had an acontractile and 8 a hypocontractile bladder. Prior to therapy, the mean residual urine volume was 461 ml. After stimulation, 32 of 48 patients were able to void with a mean residual of 57 ml. Detrusor contraction was achieved in 39% and bladder sensation was perceived by 75% of patients who failed these conditions before treatment. Following therapy, 19 of 35 patients were able to empty their bladder without the previously needed catheterization. Side effects were epididymitis in 1 and cystitis in 7 patients.
