Vanishing "ureterohydronephrosis" on technetium-99m-MDP bone scanning. 1989

F De Geeter, and V Cocquyt, and A Bossuyt, and M Jonckheer

Finding a marked bilateral renal and ureteral activity on a bone scan has been regarded as being highly specific for bilateral ureterohydronephrosis. We report here on a patient in whom this finding was not confirmed by repeated bone scanning and in whom subsequent radiologic and ultrasound examination proved normal. The possible mechanisms involved in this vanishing "ureterohydronephrosis" are discussed.

UI	MeSH Term	Description	Entries
D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D001842	Bone and Bones	A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principal cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.

D006869	Hydronephrosis	Abnormal enlargement or swelling of a KIDNEY due to dilation of the KIDNEY CALICES and the KIDNEY PELVIS. It is often associated with obstruction of the URETER or chronic kidney diseases that prevents normal drainage of urine into the URINARY BLADDER.	Hydronephroses
D000368	Aged	A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available.	Elderly
D013669	Technetium Tc 99m Medronate	A gamma-emitting radionuclide imaging agent used primarily in skeletal scintigraphy. Because of its absorption by a variety of tumors, it is useful for the detection of neoplasms.

D014517	Ureteral Obstruction	Blockage in any part of the URETER causing obstruction of urine flow from the kidney to the URINARY BLADDER. The obstruction may be congenital, acquired, unilateral, bilateral, complete, partial, acute, or chronic. Depending on the degree and duration of the obstruction, clinical features vary greatly such as HYDRONEPHROSIS and obstructive nephropathy.
