  1. Radiology Packet 36 Urinary Tract II

  2. 3-year old Shih Tzu“Maggie” • Hx: Presented because of straining to urinate.

  3. 3-year old Shih Tzu“Maggie” • RF • Two large radiopaque cystic calculi are noted in the midportion of the bladder. • Multiple smaller cystic calculi are seen. • There is a large calculus within the trigone region. • The bladder is large. • RD • Multiple cystic calculi, one is lodged in the trigone or proximal urethra causing acute bladder outflow obstruction

  4. 5-year old F Collie“Mira” • Hx: Hit by car the previous day.

  5. 5-year old F Collie“Mira” • RF • Lateral survey film • The urinary bladder is not visible and there is decrease in abdominal detail in the caudal abdominal cavity. • The retroperitoneal detail is normal. • A small, triangular mineral opacity structures is present at the ventral body wall. • Fracture of the ilial body is apparent. • Lateral film of IV pyelogram • There is no evidence of leakage of contrast material into the retroperitoneal space. • The termination of the ureters at the bladder is not defined by the study. • Contrast is present free within the abdominal cavity.

  6. 5-year old F Collie“Mira” • RD • Rupture of the urinary tract • Ilial body fracture • Small bone fragment at the ventral aspect of the abdominal wall • R/O • Rupture of the bladder or at the junction of the ureters with the bladder. • Small bone fragment suggests partial avulsion of the prepubic tendon at its attachment to the pubis. • Next • Exploratory laparotomy

  7. 10-year old Yorkshire Terrier“Berty” • Hx: Presented for evaluation of dysuria and pollakiuria.

  8. 10-year old Yorkshire Terrier“Berty” • RF • The liver is enlarged and has rounded margins. • The urinary bladder is distended. 3 large and multiple small calculi are present. • There is a calculus present in the urethra at the base of the os penis. • Large amount of intra-abdominal fat. • RD • Hepatomegaly • Cystic calculi • Urethral calculus • R/O • Hepatomegaly • Hyperadrenocorticism • Next • ACTH stimulation test and abdominal ultrasound. • Lateral radiograph with legs pulled cranially to further evaluate urethra.

  9. 14-year old FS Sheltie“Flame” • Hx: Presented with stranguria and dysuria. Some blood has be noted in the urine.

  10. 14-year old FS Sheltie“Flame” • RF • Urinary bladder is moderately distended. • There is calcific rimmed oval structure just caudal to the liver margin on the lateral view . This corresponds to an incidental finding of fat mineralization. • 8 Lumbar vertebrae are noted. • RD • Moderately distended urinary bladder • Next • Abdominal ultrasound

  11. 5-year old Pug“China” • Hx: Presented for evaluation of urethral obstruction.

  12. 5-year old Pug“China” • RF • The liver extends beyond the costal arches but the borders are sharp and clear. • The stomach wall appears mildly thick. • There are multiple mineral opacity structures noted in the urinary bladder consistent with calculi. • There is an incidental finding of bilateral coxofemoral degenerative joint disease. • RD • Cystic calculi • Next • Abdominal ultrasound

  13. 12-year old FS Sheltie“Mindy” • Hx: Presented with hematuria.

  14. 12-year old FS Sheltie“Mindy” • RF • Two discrete, roughly marginated opaque structures are present overlying the urinary bladder in both views. • The craniolateral margin of the left kidney is slightly flattened. • Mild arthritis of the right hip. • RD • Two cystic calculi • Next • Ultrasound

  15. M DSH“Scooter” • Hx: Two films are provided. The first was taken in 1999 prior to a perineal urethrostomy. The second was taken in 2001 because the patient presented with signs of urinary tract obstruction.

  16. M DSH“Scooter” • RF • 1999 • The urinary bladder contains a single 2mm round mineral opacity structure. • There is a granular appearance to the ventral aspect of the bladder suggesting that mineralized sediment is present. • Irregular mineral opacity material is present in the pelvic and proximal penile urethra. • There is an incidental finding of mild spondylosis at the lumbosacral junction. • 2001 • There are multiple variably-sized mineral opacity structures within the bladder and extending into the bladder neck. • The bladder neck appears elongated. • A gas bubble is also present within the bladder lumen. • RD • 1999 • Cystic calculi with evidence of mineralized bladder sediment • Mineralized sediment/small calculi within the urethra • 2001 • Multiple cystic calculi • Air bubble is the result of previous catheterization
