Insights
Congenital anterior urethral diverticulum (CAUD) is a rare condition causing urinary issues in children and adults. Surgical excision and primary repair effectively treated two pediatric cases presented in this study.
Area of Science:
- Pediatric Urology
- Congenital Abnormalities
Background:
- Congenital anterior urethral diverticulum (CAUD) can occur anywhere along the anterior urethra.
- Symptoms include poor urinary stream, dribbling, and urinary tract infections, often present from infancy.
- A key clinical sign is a cystic swelling of the penile urethra.
Purpose of the Study:
- To present two cases of congenital anterior urethral diverticulum (CAUD) in pediatric patients.
- To describe the surgical management of CAUD through diverticulectomy and primary repair.
Main Methods:
- Case report of two pediatric patients diagnosed with CAUD.
- Surgical intervention involving excision of the diverticulum.
- Primary repair of the urethra following excision.
Main Results:
- Successful management of CAUD in both pediatric cases.
- Restoration of normal urinary stream post-surgery.
- No reported complications in the presented cases.
Conclusions:
- Surgical excision of the diverticulum with primary repair is an effective treatment for congenital anterior urethral diverticulum (CAUD).
- Early diagnosis and surgical intervention can resolve urinary symptoms and prevent complications.
Abstract:
Congenital anterior urethral diverticulum (CAUD) may be found all along the anterior urethra and may present itself at any age, from infant to adult. Most children with this condition present with difficulty in initiating micturition, dribbling of urine, poor urinary stream, or urinary tract infection. A careful history will reveal that these children never had a good urinary stream since birth, and the telltale sign is a cystic swelling of the penile urethra. In this paper, we present two cases of CAUD that were managed by excision of the diverticulum with primary repair.

Urinary Bladder
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...

Urethra
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...
Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
