Summary

Stranguria in neonatal llamas can indicate urethral duplication, a rare condition. This case highlights the importance of considering intersex conditions in diagnosing urinary abnormalities in crias.

Area of Science:

  • Veterinary Medicine
  • Developmental Biology
  • Genetics

Background:

  • Neonatal stranguria in crias can be caused by various congenital abnormalities.
  • Early diagnosis and intervention are crucial for managing urinary tract issues in young animals.

Observation:

  • A 24-hour-old cria presented with severe stranguria and a distended bladder.
  • Physical and ultrasonographic examinations revealed no obvious external abnormalities but indicated urinary obstruction.
  • Biochemical analysis showed elevated creatinine levels, suggesting kidney compromise.

Findings:

  • Radiographic imaging (cystography and urethrography) revealed urethral duplication in the cria.
  • Necropsy confirmed bilateral ovotestes, a female reproductive tract, and urethral duplication, indicating a complex intersex condition.

  • The condition resulted in significant urinary dysfunction, necessitating euthanasia.

    • Implications:

    • Urethral duplication should be considered in the differential diagnosis of neonatal stranguria in male crias.
    • Hermaphroditism and associated intersex conditions are important causes of urethropathies in llamas.
    • This case underscores the need for thorough diagnostic workups in neonatal animals with congenital anomalies.
