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...

Urologic Endoscopic Procedure: Cystoscopic Examination

Urologic Endoscopic Procedure: Cystoscopic Examination

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Urinary Tract Infection I: Introduction

Urinary Tract Infection I: Introduction

Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...

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...

Urinary Tract Infection II: Pathophysiology

Urinary Tract Infection II: Pathophysiology

The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

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...

Area of Science:

Pediatric Urology
Surgical Pathology
Congenital Abnormalities

Background:

Urinary obstruction in infants can stem from various causes, including posterior urethral valves.
Bladder neck masses are rare but can present with significant obstructive symptoms.

Purpose of the Study:

To report a rare case of a large fibroepithelial polyp causing bladder outlet obstruction in a child.
To highlight the diagnostic and management challenges of such pediatric bladder masses.

Main Methods:

Initial ultrasonography and vesicostomy for suspected posterior urethral valves.
Subsequent Micturating Cystourethrogram (MCUG) and cystoscopy to evaluate persistent symptoms.
Surgical exploration and excision of the identified bladder neck mass.
Histopathological examination of the resected mass.

Main Results:

A 3 x 4 cm polypoidal mass at the bladder neck, near the verumontanum, was identified.
Histology confirmed a large fibroepithelial polyp with cystitis glandularis cystica.
Complete surgical excision was achieved due to a narrow pedicle.
The child experienced an uneventful recovery and remained symptom-free at 6-month follow-up.

Conclusions:

Large fibroepithelial polyps can cause significant bladder outlet obstruction in children.
Prompt surgical intervention, such as mass excision, can lead to favorable outcomes.
This case underscores the importance of thorough investigation for rare bladder pathologies in pediatric urinary obstruction.
