Massive or giant hydronephrosis has been arbitrarily defined as a hydronephrosis containing at least 1,000 ml. of fluid.1 The condition, although unusual, is not rare.1,2 It is rare, however, for the hydronephrosis to attain such proportions that clinically it simulates ascites, as occurred in the patient presented in this report. Our purpose in describing this case is (1) to emphasize the possibility that massive hydronephrosis should be considered in all instances of ascites of obscure origin, (2) to delineate certain features suggestive of such massive hydronephrosis, and (3) to call attention to the dangers attendant upon misdiagnosis.
