During conventional cystometry the patients with different types of incontinence experience the degrees of desire to void at larger volumes than in daily life. Sensation related symptoms will thus be more accurately studied with the SR-BD than with cystometry.

In patients with functional voiding disorders, the EPT can be disturbed independently of the bladder filling sensation. No significant correlation exists between volumes of filling sensations and bEPT (r < 0.005, p > 0.243). Therefore, both tests provide complementary information. Somatosensory tests of the pudendal nerve are correlated, so performing SSEP, pEPT and uEPT provides poor additional information to one of these tests alone. Somatosensory pudendal tests cannot be used to quantify filling sensation.
