The subject of this essay is computrized tomography in
urology the work in this machine had started at the sixties
but the first machine was installeted by 1973.
The scanner consist basically of an x-ray rigidly mounted
opposite a detectory array, and the system rotates around the
body, then the finely collinated x-ray beam passes through the
body, and partially absorped this is impregnated on greyscale
detectors acording to the densities and trans lated by the help
of the computer into body sectionso Where the radio-opaque
material appears white and the radiotranslucent appears black
and the cross section of the body is formed on a display monitoro
This is done for the whole body in a very small thickness of
every slice is 2 -13 mm , the distance between two slices is
very small, that a small lesion of less than 1 cm can be
diagnosed.
Initially it was used as a headscanner but soon it had
become useful for the whole body and a lot of developments and
modifications was introduced.
The main uses of computerized tomography in urology is in
kidney diseases to diagnose renal abscesses, renal cysts when it
is very small and in more than one organ. Also differentiating
solid from cystic renal masses, and extrarenal extension of any
renal pathology.
In the urinary baldder, prostate it is used in staging
of tumours and assesing the depth of penteration and extension.
In the testis it is used to identify the lymph node
metastasis and the volume of the tumour, CT also diagnose
undescended testis position, and pathology like atrophy or
malignancy. It can not be claimed that CT will replace the
conventional methods like I.V.P., ultrasonography but it
will act as a complelentary method in diagnosis, used only
when the other methods either fails or become technically
difficult to interprete.
