Urethra

Urethra

The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...

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...

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 Calculi VI: Surgical Management

Urinary 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...

Ureters

Ureters

The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

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...

Area of Science:

Pediatric Urology
Congenital Anomalies
Surgical Case Series

Background:

Urethral duplication is a rare congenital anomaly with diverse clinical manifestations.
Understanding the spectrum of presentation is crucial for timely diagnosis and management.

Purpose of the Study:

To report our experience with 4 cases of urethral duplication.
To describe the varied clinical presentations and management strategies.

Main Methods:

Retrospective chart review of 4 pediatric cases with urethral duplication.
Surgical excision of accessory urethra and correction of associated anomalies.

Main Results:

Cases presented between newborn and 10 years of age.
Presentations ranged from prepubic sinus to diphallus urethra.
Two cases of incomplete duplication (Type IA) and two of complete duplication (Effmann Type IIA2) were identified.

Conclusions:

Urethral duplications exhibit a wide range of clinical presentations.
Complete excision and correction of associated anomalies led to asymptomatic outcomes.
Successful surgical management resulted in good cosmetic results for all patients.
