[Is the lower urinary tract sensation different in patients with bladder instability?].
The author examined the sensory innervation of the lower urinary tract in two ways: by evaluation perception of bladder fullness and by determining the perception threshold to electrical stimulation of the urethral and bladder wall. The results obtained in 95 patients with detrusor instability were compared to those of 312 patients with no neurological disease and a stable detrusor. Patients with detrusor instability reported sensations of fullness at statistically significantly lower volumes than patients with a stable detrusor. In contrast, the threshold of perception of electrical stimulation was the same in the two groups, which indicates that the sensory system involved in the perception of electrical stimulation is independent of motor function, while the sensation of fullness is influenced by detrusor motor activity. These results constitute additional evidence that perception of fullness and perception of electrical stimulation are related to two different pathways of afferent innervation.
