Neurogenic bladder associated with pure cervical spondylotic myelopathy: clinical characteristics and recovery after surgery.


STUDY DESIGN Retrospective study. OBJECTIVE To examine the prevalence of lower urinary tract symptoms (LUTS) and neurogenic bladder (NB), and surgical outcomes in pure cervical spondylotic myelopathy. SUMMARY OF BACKGROUND DATA The inclusion of various types of cervical diseases, NB, and no obvious definition of NB provided the wide range of NB prevalence frequency among previous reports. METHODS Of the 220 operated patients with cervical myelopathy, 54 were selected by excluding other cervical and/or concomitant diseases contributing to LUTS. All patients with LUTS were referred to urologists and recommended to undergo urodynamic study (UDS). The presence of NB was judged by abnormal findings of UDS according to the most recent criteria and a congruity between LUTS and the course of cervical myelopathy. Patients were divided into 4 groups: no symptoms, positive symptoms without UDS examination, positive symptoms with positive NB, and positive symptoms with negative NB. Evaluation scores were compared among the groups before and after surgery. RESULTS There were no particular LUTS in NB patients. Prevalence of LUTS was 53.7% and that of NB was at least 20.4% in the patients with pure cervical spondylotic myelopathy. The scores of all 4 groups improved after surgery (P < 0.05); however, the recovery rate of NB group (47.1%) was the worst among the groups (no-symptoms group, 69.3%; negative-NB group, 53.5%; and positive symptoms without UDS group, 57.1%). Preoperative part scores showed no difference among the groups, whereas NB group demonstrated lower scores in finger and lower extremity postoperatively. A post hoc analysis confirmed a significantly poorer recovery rate related to the NB group only in the lower extremities. CONCLUSION This study is the first to describe the prevalence of LUTS and NB according to the most recent criteria in patients with pure cervical spondylotic myelopathy, which demonstrated that neurological functions in NB patients may recover; however, the extent will be limited to two-thirds of those in patients with no-NB; moreover, the remaining symptoms derive from poor lower limb function.
