Hydronephrosis. When is obstruction not obstruction?
It once was relatively simple for most urologists to diagnose ureteropelvic junction obstruction, and it was previously axiomatic that obstruction required repair to preserve and maximize renal function. Modern imaging studies have cast doubt on previously held concepts, leaving the clinician with an enigma. Prolonged follow-up of some non-operated cases has demonstrated late deterioration of function, further compounding the diagnostic uncertainty.
