EXPRESS: Azotaemia and outcomes in male cats with initial and recurrent urethral obstruction: a multicentre retrospective study of 601 cats (2020-2024).
Clinical evidence update from Journal of feline medicine and surgery
Clinical Context
Peer-reviewed veterinary literature continues to shape everyday decision-making for feline patients, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.
What the Study Evaluated
A study published in Journal of feline medicine and surgery in 2026 evaluated eXPRESS: Azotaemia and outcomes in male cats with initial and recurrent urethral obstruction: a multicentre retrospective study of 601 cats (2020-2024)..
Key Findings
ObjectivesThis study aimed to compare the prevalence and time to resolution of azotaemia between male cats presented with initial and recurrent urethral obstruction (UO), and to evaluate risk factors for extended duration of urethral catheterisation and hospitalisation.MethodsA multicentre, retrospective study of male cats that underwent urethral catheterisation for UO was conducted. Cats were excluded if they did not have a UO on presentation, had previously diagnosed chronic kidney disease, had incomplete medical records or if they were referred by another clinic after decompression. Prevalence of azotaemia (serum or plasma creatinine >...
Why It Matters for Veterinary Professionals
For veterinary professionals, the practical value of this work lies in how the findings may support more structured clinical assessment, clearer monitoring, and more informed decisions for feline patients.
Practical Interpretation
The results should be interpreted in the context of the study design, population, inclusion criteria, and clinical setting. Application in practice should consider patient-specific risk factors, available diagnostics, local standards of care, and clinician judgment.
Clinical Takeaway
Overall, the study adds useful evidence for clinicians seeking to align daily practice with current veterinary research while maintaining a balanced, case-by-case approach.
