Summary
Approximately 18.4% of canine prostatic cavitary lesions contain urine, often indicating a need for more aggressive surgical treatment beyond initial drainage. This finding aids in diagnosing intra-prostatic urethral fistulation.
Area of Science:
- Veterinary Medicine
- Canine Urology
- Surgical Pathology
Background:
- Prostatic cavitary lesions, including cysts and abscesses, are common in dogs.
- Identifying urine within these lesions is crucial for determining appropriate treatment.
- Percutaneous drainage is a common initial treatment, but its efficacy can vary.
Purpose of the Study:
- To determine the prevalence of urine-containing prostatic cavitary lesions in dogs.
- To describe the clinical management and outcomes for these lesions.
- To evaluate the utility of creatinine measurement in diagnosing urine contamination.
Main Methods:
- Retrospective study of 87 dogs with prostatic retention cysts/abscesses.
- Initial treatment involved percutaneous ultrasound-guided drainage.
- Dogs were categorized into two groups based on prostatic fluid:serum creatinine ratio to identify urine presence.
Main Results:
- Urine was present in 18.4% of prostatic cavitary lesions (16 out of 87 dogs).
- Dogs with urine in the lesion (Group 1) were more likely to require abdominal surgery (62.5%) compared to those without (15.5%).
- Creatinine measurement proved helpful in diagnosing intra-prostatic urethral fistulation.
Conclusions:
- A significant proportion of canine prostatic cavitary lesions contain urine.
- The presence of urine suggests a higher likelihood of intra-prostatic urethral fistulation.
- Dogs with urine-containing lesions often necessitate more aggressive surgical intervention than percutaneous drainage alone.

01:26Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
01:23Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

01:28Urinary Tract Calculi I: Introduction
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes 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...
01:30Urinary 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)...
