Seventeen patients with Friedreich's ataxia or spastic ataxia were subjected to an urodynamic evaluation. Fifty-three per cent (53%) of the patients presented with urinary symptoms consisting of urgent micturition and urgency incontinence. Cystometric evaluation showed a lack of inhibition of the detrusor in 7 patients (41%). Abnormal electric hyperactivity of the external sphincter was documented in 6 cases (37.5%) by electromyography. Some hypotheses are presented to explain the etiology of these abnormal findings.
对17例弗里德赖希共济失调或痉挛性共济失调患者进行了尿动力学评估。53%的患者出现了包括尿急和急迫性尿失禁在内的泌尿症状。膀胱测压评估显示7例患者（41%）逼尿肌抑制功能缺失。通过肌电图记录发现6例患者（37.5%）存在外括约肌异常电活动增强。文中提出了一些假说来解释这些异常发现的病因。
