Lower Urinary Tract Symptoms in Patients With Chronic Low Back Pain: A Cross-Sectional Study

Introduction: This study aimed to determine the extent of lower urinary tract symptoms (LUTS) in patients with chronic low back pain (CLBP) and the relationship between LUTS and patients' clinical and functional factors. Methods: Patients aged 40 to 80 who were admitted with CLBP were included. Demographic data and the duration of CLBP and LUTS were noted. Anteroposterior and lateral lumbar radiographs and lumbar MRI findings were recorded. Short Form 36 (SF-36) and the Oswestry Disability Index (ODI) were used for functional status assessment. For the LUTS evaluation, patients were asked to tick the symptoms from the list of LUTS prepared. Results: We included 90 patients with CLBP. The frequency of urinary incontinence was 81.1%. The mean number of LUTS was 2.81±3.22. The LUTS rates were higher in patients with vertebral height loss (p = 0.03), with central (p = 0.02) and lateral spinal narrow canals (p = 0.03), and with facet hypertrophy (p = 0.04). The rates of LUTS were lower in patients with decreased lumbar lordosis (p = 0.02). The ODI and LUTS were found to be related (p = 0.01). The role limitations due to physical problems of the SF-36 subgroups and LUTS were significantly correlated (p = 0.01). Conclusion: The incidence of the coexistence of CLBP and LUTS is high. Patients cannot match and report LUTS among their complaints, so physicians should inquire about LUTS in patients with CLBP and carry out the appropriate diagnosis and treatment.
