3. • Fig GU 24-1 Bladder calculi. (A) Excretory
urogram demonstrates a large stone (arrows)
in a left-sided bladder diverticulum. (B) Plain
radiograph of the pelvis shows the laminated
stone and multiple smaller calculi that were
obscured by contrast material in the right-
sided bladder diverticula on the contrast-filled
view.

4. • Fig GU 24-2 Transitional cell carcinoma. (A)
Large, irregular filling defect (arrows) in the
bladder. (B) In another patient, the irregular
tumor (open arrows) is associated with a large
filling defect (closed arrows), representing
benign prostatic hypertrophy, at the base of
the bladder.

5. • Fig GU 24-3 Benign prostatic hypertrophy.
Large, smooth filling defect at the base of the
bladder. Note the fishhook appearance of the
distal ureters and the calcification in the vas
deferens.

6. Fig GU 24-4 Carcinoma of the prostate. Elevation of and markedly
irregular impression on the floor of the contrast-filled bladder.

7. • Fig GU 24-5 Bilateral simple ureteroceles.

8. Fig GU 24-6 Endometriosis. Right posterior oblique view of the
bladder shows an irregular, rounded filling defect along the
posterior dome.24

9. • Fig GU 24-7 Cystitis. Irregular, lobulated filling
defects (representing intense mucosal edema)
at the base of the bladder.

10. Fig GU 24-8 Emphysematous cystitis. Plain film of the pelvis
shows radiolucent gas in the wall of the bladder.7

11. Fig GU 24-9 Cystitis cystica and cystititis glandularis. Oblique view
shows a nodular filling defect (arrow) in a lobulated bladder.24

12. Fig GU 24-10 Malacoplakia. Postvoiding excretory urogram shows
multiple smooth, nodular filling defects.18
