Objective:
Most multiple sclerosis patients have urological complications such as lower urinary tract symptoms. This study was conducted to evaluate the prevalence of these symptoms and whether they result in a urological evaluation.
Methods:
A cross-sectional study of 517 multiple sclerosis patients at Tehran's referral multiple sclerosis center and neurology clinics between 2018 and 2022 was performed. Data were collected through interviews after patients completed informed consent forms. Urological examinations, including urine analysis and ultrasonography, were evaluated as final assessments. The data were analyzed using descriptive and inferential statistical tests in Statistical Package for Social Science.
Results:
Among all participants, the prevalence of lower urinary tract symptoms was 73% (n = 384), with urgency (44.8% n = 232) being the most common symptom. The prevalence of intermittency was significantly higher among women (p = 0.004). There was no gender-significant difference in terms of the prevalence of other symptoms (p > 0.050). Lower urinary tract symptoms were significantly correlated with age, clinical course, disease duration, and disability (p < 0.001). Additionally, 37.3% and 18.7% of patients with lower urinary tract symptoms, as well as 17.9% and 37.5% of patients with multiple sclerosis attacks, respectively, had undergone urine analysis and ultrasonography.
Conclusion:
Multiple sclerosis patients rarely undergo urological evaluations during the course of their disease. Proper assessment is essential as these symptoms are among the most detrimental manifestations of this disease.

The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...
