Objective: Bilateral ureteral calculi, hydronephrosis, pyometra, pyocolpos, vestibulovaginal steno¬sis, and imperforate hymen in a dog are uncommon and can be difficult to diagnose. The aim of this article is to report diagnostic challenges and successful surgical treatment of this rare event and the long-term outcomes.
Materials and methods: A 5-year-old, spayed (partial ovariohysterectomy) female dog was pri¬marily diagnosed with bilateral hydronephrosis and ureter obstruction due to urolithiasis along with pyometra. The urolith was removed carefully by the right-side ureterectomy, an appropriate ureteral stent was inserted from the bladder to the right kidney, and then, a vasectomy and hys¬terectomy were performed. The dog improved and was discharged. However, 50 days after surgery, pyocolpos due to imperforate hymen and vestibulovaginal stenosis were diagnosed and sur¬gically corrected, and the ureteral stent was removed because the ureter had completely healed.
Results: During the first admission, serum biochemistry results revealed the increased blood urea nitrogen (5.9 mg/dl), creatinine (116.2 mg/dl), amylase (1,345 U/l), and lipase (141 U/l) values. After surgical correction, all parameters returned to normal. However, 50 days after surgery, the C-reactive protein concentration (143 mg/l) and white blood cell level increased (18.4 × 109/l). After a second surgical correction, the dog recovered fully within 10 days, and no postoperative complications were observed during the follow-up of 6 months.
Conclusion: This report provides diagnostic assistance and surgical treatment options for a com¬plex urogenital case. Careful examination during puberty is recommended to prevent the associ¬ated complications of this disorder.
