Abstract

Study Design A prospective observational study. Objectives To investigate preoperative prevalence of neurogenic bowel dysfunction and neurogenic bladder in patients with degenerative cervical myelopathy (DCM) and examine the degree and timing of symptom improvement after cervical decompression surgery. Factors contributing to symptom improvement were also analyzed. Methods Among 75 patients with DCM who underwent cervical decompression, Constipation Scoring System (CSS) score, International Prostate Symptoms Score (IPSS), and Japanese Orthopaedic Association (JOA) score were assessed before surgery and 1, 3, 6, and 12 months after. Prevalence rates were calculated. Data regarding patient age, sex, disease status, disease duration, lesion level, and score changes was prospectively recorded and analyzed. Results The prevalence rates of defecation and urinary dysfunction before surgery were 41.3% and 34.7%, respectively. Among the patients with defecation dysfunction, the number of patients who improved 1, 3, 6, and 12 months after surgery was 10, 9, 9, and 6, respectively. Among the patients with urinary dysfunction, the corresponding number of patients was 12, 10, 11, and 11, respectively. None of the factors we examined were significantly associated with improvement in either CSS or IPSS score; however, improvement of lower extremity JOA score tended to be associated with improvement in both. Conclusions The prevalence of symptoms of defecation and urinary dysfunction in patients with DCM was 41.3% and 34.7%, respectively. Decompression surgery improved symptoms in 20% to 46% of patients.
