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.
