The preoperative urodynamic evaluations of twenty patients with myelomeningocele who had had artificial sphincter implantation because of urinary incontinence were reviewed. Four patients developed hydronephrosis and severe impairment of renal function between two and six years after implantation of the artificial sphincter. The condition was partly reversible after removal of the artificial sphincter. The urodynamic evaluation prior to implantation revealed in the four mentioned patients compared to the 16 patients with normal upper urinary tract, a tendency to lower bladder compliance, lower bladder capacity and more severe detrusor hyperreflexia, but it was not possible to make a clear discrimination between the two groups. Attention is drawn to this unfortunate combination of effects after artificial sphincter implantation. Periodic control of the upper urinary tract by urography is recommended.
回顾了20例因尿失禁接受人工括约肌植入术的脊髓脊膜膨出患者的术前尿动力学评估情况。4例患者在人工括约肌植入术后2至6年间出现肾积水和严重肾功能损害。去除人工括约肌后，病情部分可逆。与16例上尿路正常的患者相比，上述4例患者在植入前的尿动力学评估显示膀胱顺应性较低、膀胱容量较小以及逼尿肌反射亢进更严重，但无法在两组之间做出明确区分。需注意人工括约肌植入术后这种不良效应的组合。建议通过尿路造影对上尿路进行定期检查。
