Fifty-five consecutive male patients aged 18-77 with chronic retention of urine were investigated urodynamically. All were shown to have obstructed micturition. Inflow cystometry defined two groups, one with high-pressure and one with low-pressure filling. Recent-onset enuresis and upper-tract dilatation as seen on radiography were significantly associated with high-pressure bladder filling. Postoperative studies showed that patients with high-pressure filling on preoperative cystometryhad a better response to outflow-tract surgery. The poor response of the patients with low-pressure filling was due to a high incidence of inadequate detrusor contraction leading to persistent residual urine. Thus urodynamic studies may be used to indicate which patients are likely to benefit from prostatectomy and, after the operation, whether the obstruction has been relieved.
对55例年龄在18至77岁之间的慢性尿潴留男性患者进行了尿动力学研究。所有患者均表现为排尿梗阻。充盈性膀胱测压确定了两组，一组为高压充盈，另一组为低压充盈。近期出现的遗尿和影像学检查所见的上尿路扩张与高压膀胱充盈显著相关。术后研究表明，术前膀胱测压为高压充盈的患者对流出道手术反应较好。低压充盈患者反应不佳是由于逼尿肌收缩不足导致残余尿持续存在的发生率较高。因此，尿动力学研究可用于表明哪些患者可能从前列腺切除术中获益，以及术后梗阻是否已解除。
