Abstract
Objective-To evaluate the effect of saline (0.9% NaCl) solution administere d IV to induce diuresis on 15 dimensional variables of the kidneys, size of renal pelvis, and diameter of the cranial part of the ureters. Animals-25 dogs without evidence of renal disease that were undergoing chem otherapy for various neoplasms. Procedure-The kidneys, cranial aspect of th e ureters, and trigone area of the urinary bladder of each dog were examine d ultrasonographically before and during IV administration of saline soluti on (2.7 to 18.8 ml/kg of body weight/h). Results-Ultrasonography revealed unilateral and bilateral pyelectasis durin g diuresis in 16 of 23 (70%) dogs but unilateral pyelectasis in only 1 dog before diuresis. Unilateral pyelectasis during diuresis was observed in 11 of 16(69%) dogs. Pyelectasis during diuresis was categorized as slight in 1 5 of 21 (71%) kidneys. Degree of pyelectasis during diuresis was not identi cal in both kidneys of 13 of 16 (81%) dogs. Diuresis did not induce uretere ctasis, and it did not cause changes in 15 dimensional variables of the kid neys. Conclusions-In nonsedated, nonazotemic dogs, IV administration of saline so lution to induce diuresis may cause slight pyelectasis without evidence of ureterectasis. Clinical Relevance-When dilatation of the cranial part of the ureter is > 2 mm at the same time that ipsilateral pyelectasis is detected during ultras onographic examination of the urinary tract system of a nonsedated, nonazot emic dog receiving IV administration of saline solution to induce diuresis, additional examinations are recommended to determine the possibility of ea rly obstructive nephropathy or pyelonephritis.
