Summary
High-frequency ultrasonography is key for diagnosing scrotal diseases like epididymitis and epididymo-orchitis. This review details sonographic features of various epididymal pathologies, aiding radiologists in accurate diagnosis and management.
Area of Science:
- Radiology
- Medical Imaging
- Urology
Background:
- Acute scrotal pain is commonly caused by epididymitis and epididymo-orchitis.
- Differentiating these conditions from testicular torsion is critical for timely management.
- High-frequency ultrasonography is the preferred imaging modality for scrotal evaluation.
Purpose of the Study:
- To review the sonographic features of diverse epididymal pathologies.
- To enhance radiologists' understanding of conditions affecting the epididymis.
- To differentiate infectious and noninfectious epididymal conditions.
Main Methods:
- Review of sonographic findings in various epididymal diseases.
- High-frequency transducer ultrasonography for detailed epididymal visualization.
- Presentation of imaging characteristics for benign and malignant epididymal lesions.
Main Results:
- Detailed sonographic features of infectious and noninfectious epididymitis/epididymo-orchitis are presented.
- Imaging findings for benign epididymal lesions (cysts, spermatoceles, tubular ectasia, sperm granulomas) are described.
- Sonographic appearances of malignant epididymal tumors (lymphoma, metastases) and other conditions (trauma, torsion) are discussed.
Conclusions:
- Ultrasonography is essential for evaluating acute and nonacute scrotal pathology.
- Understanding diverse sonographic features aids in diagnosing epididymal conditions.
- This review provides a comprehensive guide for radiologists managing scrotal diseases.

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.

01:28Imaging Studies I: Kidney, Ureter, and Bladder Studies
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...
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...

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...
01:27Imaging Studies III: Computed Tomography
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...
01:27Imaging Studies IV: Magnetic Resonance Imaging
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,...
