title: Prognosis of radiologically non-functioning obstructed kidneys.
abstract: Twenty patients found to have unilateral radiologically non-functioning obstructed kidneys on excretory urography (IVU), and who had normal contralateral kidneys, were further evaluated. Ultrasonography, radionuclide imaging and CT scan were carried out pre-operatively to try to predict which of the kidneys were potentially recoverable after relief of obstruction. Percutaneous nephrostomy was also performed on the last consecutive 7 patients 4 weeks before definitive treatment and the function of the kidneys determined daily. The patients were re-evaluated 2 months after the relief of obstruction. Ultrasonography, radionuclide imaging and CT scan were not found to be reliable in predicting whether these kidneys were potentially recoverable. We consider percutaneous nephrostomy a good procedure for obtaining prognostic information prior to definitive surgery.
