パーキンソン病,多発性硬化症,脊髄小脳変性症の診察においては,原疾患の重症度の軽い時期から排尿症状の出現することが多く,また,原疾患の重症度が変化しなくても下部尿路機能の病態が変化する可能性があることを念頭におくことが必要である.また,症例ごとに下部尿路機能障害の病態・ADLレベル及び介助者の有無等の背景因子を考慮することで,腎機能保護ならびにQOLの向上を目指した排尿方法の選択が可能であるClinical symptoms, urodynamic findings, and urological treatment of 35 patients with neurogenic bladder dysfunction caused by Parkinson's disease (11 patients), multiple sclerosis (10 patients), and spinocerebellar degeneration (14 patients) were reviewed retrospectively. Most of the patients had a relatively low stage of disease, when they were first seen by their urologists. Chief urological complaints were of irritation in 63.6% of Parkinson's disease and 64.3% of spinocerebellar degeneration cases, compared with obstruction in 80.0% of multiple sclerosis cases. Cystometry revealed underactive detrusor function in 69.2% of the patients with spinocerebellar degeneration but no abnormalities in the patients with Parkinson's disease or multiple sclerosis. Of 34 patients, excluding one patient lost to follow-up, the period of urological management ranged from one to 44 weeks with a mean of 11.0. The final methods of urinary drainage in 34 patients consisted of voluntary voiding in 20, clean intermittent catheterization in 11 including eight by self catheterization, incontinence into diaper in two, and indwelling catheter in one. Five patients were compelled to change urinary drainage method from voluntary voiding to clean intermittent catheterization because of increasing residual volume in four and progressing bladder deformity in one. However, none of them showed the clinical signs of primary disease progression. These findings indicate that in patients with Parkinson's disease, multiple sclerosis, and spinocerebellar degeneration, the urological symptoms can appear even in the early stage of disease. In addition, close follow-up is important in the urological management of neurogenic bladder patients with these diseases, because the disorders of the lower urinary tract may progress regardless of the status of the primary disease.
