Evaluation of transplanted kidneys with computed tomography and ultrasound

165 computed tomography (CT) and 98 ultrasound (US) examinations were performed in 64 renal transplant patients. The correlations between CT/US, contemporary clinical and retrospective diagnoses were analysed. CT and US are of great help in the post transplantation follow up, particulary when used together. Determination of the cause for unsatisfactory transplant function had always constituted one of the major problems for the clinician involved in the care for organ transplant patients. Traditionally transplant malfunction had been investigated by clinical examination, renography, radionuclearscanning, angiography and needle biopsy. (Nilsson et al. 1968. Starzl et al. 1970. Häyrö 1981). Computed tomography (CT) and ultra sound scanning (US) show promising capacities to differentiate between the alternative causes for diminished transplant function. (Frick et al. 1981, Smith 1981). The purpose of this presentation is to evaluate CT and US in the diagnosis of the various conditions causing impaired function of the transplanted kidney.
