Spontaneous urinary extravasation during a diuretic radionuclide renal study. Report of two cases.

Spontaneous urinary extravasation has been observed in excretory urography, but this complication has not been reported when a diuretic radionuclide renal study is used. This study reports two cases demonstrating this phenomenon. The lack of documentation of this occurrence may be related to the infrequency of this complication.

Indium 111 white blood cell imaging of epididymitis.

The clinical diagnosis of epididymitis is frequently substantiated radiographically with pertechnetate 99m (99mTc) testicular scintigraphy and scrotal sonography. Indium 111 (111In) autologous leukocyte imaging in a patient with epididymitis has to our knowledge not been reported previously. The case presented is an elderly man with epididymitis.

Prospective analysis of strategies for diagnosing renovascular hypertension.

Renovascular hypertension is a potentially curable form of high blood pressure. However, it is unclear how best to select patients who are likely to have renovascular hypertension, what diagnostic strategy to use in these selected patients, and how to predict the hemodynamic significance of a renal artery stenosis. We determined the prevalence of renovascular hypertension in adults who exhibited suggestive clinical features.
