After external urethral sphincterotomy 7 patients were found to have residual urine in excess of 80 ml. By measurement of the urethral pressure and analysis of the cystometrogram it was found that these patients fail to sustain bladder contraction and, thereby, fail to empty the bladder completely.
在进行尿道外括约肌切开术后，发现7名患者残余尿量超过80毫升。通过测量尿道压力和分析膀胱测压图，发现这些患者无法维持膀胱收缩，因此不能完全排空膀胱。
