Urinary Obstruction

Part of the Medical Radiology book series (MEDRAD)


Urinary tract obstruction is a common urologic problem occurring at all ages. If left untreated, obstruction invariably results in loss of renal tissue and function, the extent of which depends on duration and severity of the obstruction, unilateral or bilateral renal involvement, and the presence of preexisting renal disease. Furthermore, obstructive uropathy enhances the progress of superimposed infection, often leading to pyonephrosis, sepsis, and rapid renal and systemic failure.
