KIDNEY URETER newer investigations 3


 NEWER TECHNIQUES
4.1 Ultrasound Scan (U.S)
This is a non-invassive investigation and has to a large  extent,
replaced radiologic tests in obtaining information regarding  the
kidney.  This  scan can be of renal failure can  tell  difference
between  solid  and  cystic lesions. Transrectal  U.S.  can  give
information of size of prostate.

4.2 Computerized Tomography (C.T.)
Especially  required for assessment of the  retroperitoneium  and
eliminating  the possibility of adrenal tumours  in  differential
diagnosis of flank masses.

This scan is used in cases of renal tumour to identify renal vein
involvement. It is also usefull for accurate staging of tesicular
tumours.

4.3 Arteriograms
This  test is less often used, since information can be  obtained
by ultrasound and C.T. scans. Information regards vascularity  of
the  lesion  can be had with this test. It can be  of   value  in
renal trauma cases.
In very vascular lesions, embolisation of the tumour vessels  can
also be done.

4.4 Radioisotopic Studies
Radioisotopic  labelled substances (DTPA, hippuran)  excreted  by
the  glomerulus  or  tubules provide a  functional  scan  of  the
kidney.  Information on relative function of different  areas  of

the kidney can be obtained.
