Renal stones
Calcification of the urinary bladder wall
bladder exstrophy
radiographic appearance in bladder exstrophy. It describes wide midline separation of the pubic bones.Bladder exstrophy (also known as ectopia vesicae) refers to a herniation of the urinary bladder through an anterior abdominal wall defect. The severity of these defects is widely variable.

Normal IVU series
Failure of contrast to pass to ureters due to both sided mid ureteric stones
LT sided upper Ureteric stones
Bilateral HU + HN
Bulb of follys cathter IVU with bilateral mild to moderate degree of HN
RT sided PUJ stenosis & obstruction with RT sided HN
Uretrocele (cobra head shape)distal both sided ureteric ends with dilated both ureters
