Assessment of lower urinary tract dysfunction in women with multiple sclerosis

Multiple sclerosis (MS) is a chronic disorder of the central nervous system affecting primarily young women. Neurogenic lower urinary tract dysfunction (NLUTD) represents one of the disease manifestations creating the risk of infectious complications and kidney disease. Today, there is insufficient data on the urinary microflora composition obtained by advanced high-tech diagnosis methods. The study aimed to perform clinical assessment of NLUTD associated with MS and its impact on the quality of life (QOL), as well as to clarify the data on the urinary microflora composition. A total of 33 women with MS aged 36 [39.5; 30.5] years were assessed using the customized questionnaires for estimation of the NLUTD prevalence and severity, as well as for QOL evaluation. Qualitative determination and quantification of urinary opportunistic microflora (OM) were performed using the real-time polymerase chain reaction. A total of 19 (57.6%) women with MS had symptoms of NLUTD: symptoms of the storage (15 individuals, 45.5%) and emptying (16 individuals, 48.5%) phases. In almost half of women with MS, the complaints included abnormalities of both bladder functioning phases (12 individuals, 36.4%); moderate abnormalities prevailed (12 individuals, 34.6%). Women with MS and NLUTD were more disabled based on the EDSS score (3.5 [5.0; 3.0] points; p < 0.001) and had longer disease duration (13 [20.0; 5.0] years; p < 0.001). The QOL index of women with NLUTD showed dissatisfaction with bladder function. The study revealed bacteriuria in patients with MS and NLUTD. The data on the urinary microflora composition are provided: OM members (bacteria of the ESKAPE group) have been found in 8 samples obtained from women with MS and NLUTD. Bacteriuria was asymptomatic.
