Plain-English summary
A 3-year-old English Cocker Spaniel was brought in for persistent urinary incontinence, which continued even after surgery to remove reproductive organs. Tests showed that the dog had a rare condition called XX sex reversal, where the reproductive organs didn't develop normally. An unusual fluid-filled structure was found near the bladder, and it was connected to the urethra and remnants of the uterus. After surgery to remove this abnormal structure, the dog's urinary incontinence was resolved.

Abstract
A 3-year-old dog weighing 8 kg was referred with a disorder of sexual development and persistent urinary incontinence before and after gonadohysterectomy performed at a local animal hospital. Histopathological examination disclosed hypoplasia of the testes, epididymis, pampiniform plexus, and uterus. On ultrasonography, an anomalous structure containing anechoic fluid was identified in the region dorsal to the urinary bladder. An anomalous communication between the proximal urethra and the remnant uterus and vagina was found on retrograde urethrography under fluoroscopy. Reflux of contrast medium into the anomalous structure, suspected to be the uterus and cranial vagina, from the urethra was detected. Computed tomography identified the anomalous structure between the rectum and urethra. The anomalous structure was removed via laparotomy and the urinary incontinence resolved. The diagnosis of XX sex reversal with a developmental anomaly of the genitourinary tract was made on the basis of laparotomy findings and cytogenetic and SRY gene analyses.
