Ultrasonography of the Adult Male Urinary Tract for Urinary Functional Testing
Published on: August 14, 2019
Urinary tract ultrasonography in normal rams and in rams with obstructive urolithiasis
Summary
Ultrasonography effectively diagnosed obstructive urolithiasis in rams by revealing urinary tract abnormalities. This imaging technique established diagnostic criteria for kidney, ureter, bladder, and urethra conditions in affected animals.
Area of Science:
- Veterinary Medicine
- Diagnostic Imaging
- Urology
Background:
- Obstructive urolithiasis is a significant health concern in rams.
- Accurate diagnosis is crucial for effective treatment and management.
- Ultrasonography offers a non-invasive method for evaluating the urinary system.
Purpose of the Study:
- To establish ultrasonographic criteria for diagnosing obstructive urolithiasis in rams.
- To determine normal ultrasonographic measurements of the ovine urinary tract.
- To compare findings in healthy rams with those affected by urolithiasis.
Main Methods:
- Ultrasonography was performed on 20 healthy adult rams and 7 rams with obstructive urolithiasis.
- A 5.0 MHz convex transducer examined kidneys; a 5.0 MHz linear rectal transducer examined the bladder and urethra.
- Examinations were conducted transrectally and over the paralumbar fossa on standing rams.
Main Results:
- Normal ultrasonographic dimensions for ovine kidneys, renal sinus, and medullary pyramids were established.
- Rams with obstructive urolithiasis exhibited markedly dilated urethra and urinary bladder.
- Ultrasonography revealed renal pelvis and medullary pyramid dilation, uroperitoneum, and organ rupture in affected rams.
Conclusions:
- Ultrasonography is a valuable diagnostic tool for obstructive urolithiasis in rams.
- Established criteria aid in identifying urinary tract abnormalities associated with urolithiasis.
- This imaging modality assists in diagnosing complications such as uroperitoneum and organ rupture.

01:24Imaging Studies II: Ultrasonography
IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
01:22Imaging Studies V: Intravenous Urography and Retrograde Pyelography
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. Intravenous Urography (IVU)Intravenous...
01:30Urinary Tract Calculi III: Medical Management
The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...
01:25Urinary Tract Calculi VI: Surgical Management
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

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,...

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...
