Even 60 years after its first clinical application intravenous urography (IVU) is still an essential part of basic diagnostic measures in benign hyperplasia of the prostate (BPH). We compared the value of the IVU to the ultrasound examination in the preoperative evaluation prospectively in 79 patients. Out of a total of 16 pathological findings (20%), only 5 findings (6.3%) could be proved in the IVU. If there was no clinical relevance, however, no treatment was necessary; neither did the pathological findings influence the strategy of surgery. Indirect signs of a tumour in 3 IVU's could be identified ultrasonically as parapelvic or cortical cysts, respectively. In addition to reliable and reproducible estimates of prostatic size, ultrasonography provides information on the residual volume, dilatation of the upper urinary tract, renal masses or stone disease. We recommend ultrasound examination as a helpful method in the preoperative evaluation of BPH. IVU should be considered only for answering specific and clinically relevant questions.
即使在首次临床应用60年后，静脉尿路造影（IVU）仍是前列腺良性增生（BPH）基本诊断措施的重要组成部分。我们前瞻性地比较了79例患者术前评估中IVU与超声检查的价值。在总共16项病理结果（20%）中，IVU仅能证实5项结果（6.3%）。然而，如果没有临床相关性，则无需治疗；病理结果也不影响手术策略。3例IVU中的肿瘤间接征象经超声检查分别确认为盆腔旁囊肿或皮质囊肿。除了对前列腺大小进行可靠且可重复的评估外，超声检查还能提供残余尿量、上尿路扩张、肾肿块或结石病的信息。我们推荐超声检查作为BPH术前评估的一种有用方法。仅在回答特定且与临床相关的问题时才应考虑IVU。
