Urinary Bladder

Urinary 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...

Anatomy of the Genitourinary System II: Bladder and Urethra

Anatomy of the Genitourinary System II: Bladder and Urethra

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Nursing Assessment of the Genitourinary System II: Inspection and Palpation

Nursing Assessment of the Genitourinary System II: Inspection and Palpation

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease. Look for...

Disorders of the Male Reproductive System

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra. Symptoms...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Imaging Studies VI: Voiding Cystourethrography and Cystography

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...

Area of Science:

Urology
Surgical Pathology

Background:

Male urethral diverticula are uncommon congenital or acquired conditions.
Acquired diverticula often arise secondary to infection, strictures, or trauma.

Observation:

A 71-year-old man presented with a large scrotal mass and urinary retention.
Symptoms stemmed from an untreated urethral injury sustained 15 years prior.
Imaging revealed an anterior urethral diverticulum containing stones.

Findings:

Open diverticulectomy was performed for the symptomatic urethral diverticulum.
Pathologic examination confirmed the diverticulum was lined by granulation tissue.
The patient experienced a successful recovery post-surgery.

Implications:

This case underscores the potential long-term complications of untreated urethral injuries.
Accurate diagnosis of urethral diverticula requires a comprehensive approach including history, physical exam, imaging, and pathology.
Surgical intervention can effectively manage symptomatic urethral diverticula.
