Radionuclide imaging in urology.
Radiopharmaceutic tracers are used commonly to diagnose and monitor benign and malignant conditions of the genitourinary system. Most often, these tracers assess renal function and obstruction in "normal" and transplanted renal units. More recently, especially with the advent of positron emission tomography (PET)/CT, the role of nuclear pharmaceutics in the staging and monitoring of malignancies has expanded.

Presentation of a functional pituitary adenoma as a significant decrease in prostate-specific antigen level in a patient followed for prostate cancer.
The stimulatory role of testosterone in the production and release of prostate-specific antigen (PSA) has been well characterized. Testosterone production by the testes is dependent on a functional hypothalamic-pituitary-gonadal axis. High prolactin levels have been shown to disrupt this axis, resulting in decreases in gonadotropins and testosterone levels. We report a patient with prostate cancer and elevated PSA levels followed with "watchful waiting" for several years who experienced a precipitous decrease in PSA level over a 3 month period. The patient was found to have an asymptomatic prolactin-secreting pituitary macroadenoma.
