Urinary symptoms interfered with daily life in 88%\/92% and sexual life in 72%\/67% of sexually active men\/women. Symptoms of disturbed bladder emptying were the most common (95%\/92% men\/women), followed by urinary incontinence (56%\/71%) and symptoms of overactive bladder (40%\/56%). Perianal sensation was abnormal in 96%, EMG of the EAS muscle in 88%, and sacral reflex in 84% of patients. In 40%\/17% men\/women, a postvoid residual (\u2009&gt;100 ml) was found. On filling cystometry overactive bladder was found in 21%\/0%, reduced detrusor capacity in 9%\/15%, and during voiding phase an acontractile detrusor or detrusor underactivity were found in 59%\/85% men\/women. Using multiple linear regression analysis, perianal sensory loss (<jats:italic>P<\/jats:italic>\u2009=\u20090.0001) and female gender (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.02) had a significant positive effect on urinary incontinence score.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our study demonstrated significant LUT dysfunction, which disturbed the life of the majority of patients with chronic lesions of the cauda equina.
