An assessment of computerised isotopic renal section scanning

The basic non-invasive investigation of renal space occupying lesions by excretion pyelography was coupled with ultrasonic scanning. Forty-one patients who have undergone isotopic section scanning as part of their investigative assessment were studied. The conditions investigated included solitary cysts, polycystic kidneys, renal tumours, tumefactive xanthomatous pyelonephritis, renal infarct and non-functioning kidneys. An analysis of the accuracy of isotopic section scanning in these different pathological states was made. Computerised isotopic section renal scanning offers a new non-invasive renal investigative technique.
