We reported two cases of dysuria caused by intrapelvic urethral trauma secondary to pelvic fracture. Case 1 (A 1-year-old male crossbreed dog, 3.1 kg) presented with pelvic fracture and dysuria. The urethral rupture was diagnosed by retrograde urography and the urethral anastomosis was performed. The dog has been urinating voluntarily but still has urinary incontinence at 16 months after the surgery. Case 2 (1-year-old male Miniature Dachshund, 3.7 kg) started to have dysuria at 7 days after the pelvic fracture repair. The urethral stricture was diagnosed by retrograde urography. The first resection of urethral constriction and end to end anastomosis resulted recurrent urethral stricture. Therefore, the urinary diversion via preputial urethrostomy was performed. The dog has been urinating voluntarily at 10 months after the surgery.
Fourteen hip joints of 8 juvenile dogs with hip dysplasia were evaluated by radiographic and arthroscopic examinations. The purpose of the study was to evaluate the relationship between radiographic and arthroscopic findings. Radiographic hip osteoarthritis grades were obtained from the ventrodorsal hip-extended view. The distraction index (DI) for each hip joint was calculated from the compression and distraction views. Articular cartilage pathology, the condition of the ligament of the femoral head and the synovium were evaluated by arthroscopy. Results showed that dogs with higher DIs were likely to have more severe cartilage injuries in the hip joints. Hip arthroscopy was useful for evaluating joint pathology and the findings seem to correlate with joint laxity in young dogs with hip dysplasia.
A 2-year-old male lop eared rabbit was presented for anorexia, lethargy and anuria. Abdominal radiographs revealed urinary calculi in the both ureteres. The calculi were removed by ureterotomy, and the rabbit made a full recovery. However, the ureterolith was recurred and the rabbit died after the second recurrence. It seemes that surgical removal of ureterolith is one of the choices of the treatment of ureterolithiasis in rabbits, but further study is needed to prevent the recurrence of ureterolith in rabbits.
A 14 month-old Yorkshire terrier was presented with hyperammonemia and neurological disorder. Helical computed tomographic portography showed a single extrahepatic portosystemic shunt between left colic vein and caudal vena cava. Mesenteric portography after laparotomy revealed the other shunt inconsistently visualized around left gastric vein. The both shunts were safely ligated and hyperammonemia was disappeared. This case report shows a rare case of extrahepatic CPSS in a dog and the importance of mesenteric portography especially after shunt ligation, not for missing other shunts.
