Ten men were subjected to transurethral electroresection because of prostatic adenoma. All were examined with urethrocystography on 3 occasions, viz. at the end of operation, 4-7 days later and after a further 2-3 months. Peroperative examination for residual adenoma appeared to be of little value, while examination a few days after the operation revealed residual adenomas in 2 cases and possibly also in a third. The cavity left after the operation had the same size at the peroperative and the first postoperative examination, though its outline was sometimes smoother at the latter. During urination the cavity invariably increased in size. At the second postoperative examination the operation cavity was clearly smaller and its outline smoother in 9 of 10 cases. The cavity still expanded during micturition. No passage of contrast medium to the veins was ever demonstrable. At the peroperative examination the contrast medium was not injected under any substantial pressure and the cavity was not exposed to pressure by micturition. Even at the first postoperative examination, when the operation cavity was exposed to pressure by urination, the veins that had been opened at operation had closed so effectively that no contrast medium passed outside the prostatic capsule. Urethrocystography in association with TUR of prostatic adenoma is of interest to the urological surgeon. It provides him with a possibility to check his work very carefully.
10名男性因前列腺腺瘤接受了经尿道电切术。所有患者均接受了3次尿道膀胱造影检查，即手术结束时、术后4 - 7天以及再过2 - 3个月后。术中对残余腺瘤的检查似乎价值不大，而术后几天的检查发现2例有残余腺瘤，可能还有第3例。手术结束时及术后首次检查时，术后留下的腔隙大小相同，不过术后首次检查时其轮廓有时更平滑。排尿时腔隙大小总是会增加。术后第二次检查时，10例中有9例手术腔隙明显变小且轮廓更平滑。排尿时腔隙仍会扩张。从未证实有造影剂进入静脉。术中检查时，造影剂并非在任何较大压力下注入，且腔隙未因排尿而受到压力。即使在术后首次检查时，当手术腔隙因排尿而受到压力时，手术中开放的静脉已有效闭合，以至于没有造影剂通过前列腺包膜外。前列腺腺瘤经尿道电切术联合尿道膀胱造影术对泌尿外科医生来说很有意义。它为医生提供了非常仔细检查其手术效果的可能性。
