我们前瞻性研究中风病人的膀胱功能,以判定中风发生后尿失禁的机制。 选入51例近期患单侧半球缺血中风恢复期的病人为研究对象,对所有尿失禁的19例病人进行尿动力学研究。 51例中19例患尿失禁,尿失禁与病灶的大面积梗塞、失语、认识力损害和一般状况差有关(P<0.05),与年龄、性别、中风发生的左右侧别及中风发生到进入研究的时间无关。19例尿失禁病人进行尿动力学研究,发现反射性膀胱37％,正常占37％,无张力性膀胱20％,逼尿肌、括约肌失调5％。所有尿动力学检查异常者有失语、痴呆或严重 We prospectively studied the bladder function of stroke patients to determine the mechanism of urinary incontinence after a stroke. A total of 51 patients with recent recovery from unilateral hemispheric ischemic stroke were enrolled in this study. Twenty-nine patients with urinary incontinence underwent urodynamic studies. Among the 51 cases, urinary incontinence was found in 19 cases, and urinary incontinence was related to large infarct, aphasia, impairment of cognitive ability and poor general condition (P <0.05), with age, gender, stroke and left and right side and stroke occurred Study time has nothing to do. Nineteen urinary incontinence patients underwent urodynamic studies and found that 37% of reflexive bladder, 37% of normal, 20% of non-tonic bladder, detrusor and 5% of sphincter were negative. All patients with abnormal urodynamic tests have aphasia, dementia or severe
