Summary
Radiographs taken before relieving feline urethral obstruction improve diagnosis rates. Urethral plugs were the most common cause identified in cats with urinary obstruction.
Area of Science:
- Veterinary Radiology
- Urology
- Small Animal Internal Medicine
Background:
- Feline urethral obstruction is a common emergency.
- Accurate diagnosis of the underlying cause is crucial for effective treatment.
Purpose of the Study:
- To investigate causes of feline urethral obstruction.
- To compare radiographic diagnosis frequency before and after urethral unobstruction.
Main Methods:
- Retrospective cross-sectional study of cats with first-time urethral obstruction.
- Radiographic evaluation integrated into initial assessment.
- Comparison of diagnosis rates between pre- and post-unobstruction radiography.
Main Results:
- 80 cats (52%) had pre-unobstruction radiographs; 73 (48%) had post-unobstruction radiographs.
- Higher diagnostic frequency in cats radiographed before unobstruction (61% vs. 45%).
- Urethral plugs were significantly more frequent when diagnosed before unobstruction (45% vs. 5.5%).
Conclusions:
- Pre-unobstruction radiography offers a diagnostic advantage for feline urethral obstruction.
- Urethral plugs are the predominant cause of obstruction.
- Timing of radiography impacts diagnostic yield in obstructed cats.

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
