Overview
Abdominal CT scan may be helpful in the diagnosis of hydronephrosis. Findings on CT scan suggestive of hydronephrosis include dilation of the proximal ureter,

The choice of imaging depends on the clinical presentation (history, symptoms and examination findings):
In the case of renal colic (one sided loin pain usually accompanied by a trace of blood in the urine) the initial investigation is usually an intravenous urogram. This has the advantage of showing whether there is any obstruction of flow of urine causing hydronephrosis as well as demonstrating the function of the other kidney. Many stones are not visible on plain xray or IVU but 99% of stones are visible on CT and therefore CT is becoming a common choice of initial investigation.
Patient #1: CT images demonstrate marked left hydronephrosis secondary to a calculus in the proximal right ureter
