RADIOGRAPHIC EVALUATION OF EXPERIMENTALLY-INDUCED NEPHROSIS IN GOATS

Intravenous pyelography (IVP) with pneumoperitoneum (PP) was undertake n in normal and induced nephrotic goats. In normal goats, the techniqu e provided visualization of both the kidneys, renal pelvis, ureter and urinary bladder at 10 min post-administration of sodium iothalamate ( 70%). In mercuric chloride- and oxytetracycline-induced nephrosis in g oats, the urinary tract could not be visualized even 60 min post-admin istration of dye indicating severe failure of renal excretory function . However, in gentamicin-abused goats, renal excretory function was no t significantly altered owing to a very mild renal damage. It was conc luded that IVP with PP could be a dependable diagnostic lest for varie d degree of renal insufficiency in ruminants.
