title: Renal carcinomas missed by urography.
abstract: It is well accepted that renal masses are missed on intravenous urography. We present 3 patients with renal carcinoma; their tumours, measuring between 3 and 5 cm, were not detected on good quality IVU but were demonstrated on ultrasound. We wish to emphasise the importance of performing an ultrasound or computed tomography examination in cases where a renal tumour is suspected when the IVU is normal.
