RADIOISOTOPIC SCANNING IN UROLOGICAL PRACTICE

Abstract

There a re widespread application for radionuclide imaging in patients with urologic diseases. A large number of radioisotopes have been developed for the investigation of specific anatomic and functional disorders, primarily of the kidneys but also of other organs of the genitourinary tract the most common radioisotopes used are technetium-99m (9901Tc) and Iodine 131 c3lr). Radioisotopes are used to demonst rate patho-physiologic changes that result from a bnormalities in.the perfusion and function of the organ. As regard scanning of the kidneys rad i oisotopes to d etect the presence of interna l mass lesion or a ny vascular a bnor ma lities. Also , diffuse renal diseases of the kidney, reno ascular • hypertension and obstructive uropathy a re well demonstrated by rad ioisotopic scanning. Eva luation of the renal transplants, renal colic make rad ioisotopes have a great deal in urological practice. Fa r away of the kidneys radionuclides were used in imag ing the scrotum to detect torsion of the testes or infla mmatory conditions a nd other pathological conditions. Also, radioisotopes scanning evaluate most .of di seases in the ureter, urinary bladder and prostate. Other applications of radioisotopic scanning of the urogenital system are much but for example, the role in evaluation of renal function in children, follow up of renal function after extracorporeal shock wave lithotripsy, indirect radionuclide cystography is posterior urethral valves and the great diagnostic value of radioisotopic erection penogram for vasculogenic impotence.
