Computed tomography of the genitourinary tract.

Eighteen months of experience with computed body tomography have revealed that this radiologic modality is useful in the diagnostic evaluation and management of urologic patients. Renal masses, perirenal lesions, poorly functioning kidneys, pelvic tumors and associated retroperitoneal nodal spread and other diagnostic problems related to the urinary tract have been imaged successfully with computed body tomography. Accuracy is high in the differentiation of benign renal cysts from renal neoplasms. Tumor staging and computed body tomography is being explored currently.
