Abstract
We evaluated the clinical results of microendoscopic surgery for lumbar disc herniation (LDH) and lumbar spinal canal stenosis (LCS) in 44 patients (including 7 hemodialysis or renal transplantation patients), who were followed up to determine the degree of improvement in the JOA score, along with data obtained using a visual analog scale (VAS), the Roland-Morris Disability Questionnaire (RDQ), and the Self-Rating Depression Scale (SDS). The mean scores for the JOA, VAS, RDQ and SDS improved in patients who were not receiving hemodialysis, whereas hemodialysis or renal transplantation patients showed deterioration in the mean VAS for lower back pain and the RDQ. We investigated the instability of the lumbar spine using X-ray and magnetic resonance imaging (MRI), and found no significant deterioration. In this study, the relationship between lower back pain and instability of the lumbar spine was unclear, but we conclude that the long-term outcome of hemodialysis or renal transplantation patients requires more careful attention.
