Summary
Urethral duplication, a rare congenital anomaly, is infrequently associated with anorectal malformations. This report details two unique cases, highlighting endoscopic and surgical interventions for this rare condition.
Area of Science:
- Pediatric Surgery
- Congenital Anomalies
- Urology
Background:
- Urethral duplication is a rare congenital anomaly with varying presentations.
- Anorectal malformations are more common and often present with other anomalies.
- The co-occurrence of urethral duplication and anorectal malformation is exceptionally rare.
Observation:
- This report presents two pediatric cases with the rare association of urethral duplication and anorectal malformation.
- Case 1 involved a urethral duplication where the septum was managed endoscopically.
- Case 2 involved a urethral duplication that required surgical excision.
Findings:
- The study highlights the rarity of combined urethral duplication and anorectal malformation.
- Successful management strategies included endoscopic septotomy and surgical excision of the duplicated urethra.
- These interventions demonstrate feasible approaches for this complex anomaly.
Implications:
- This case series expands the understanding of rare congenital anomalies.
- It provides insights into potential management strategies for combined urethral duplication and anorectal malformation.
- Further research may elucidate the underlying mechanisms and optimal treatment pathways for such rare conditions.

01:19Anatomy 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...
01:16Urethra
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...

01:22Ureters
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...
01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
01:20Disorders of the Urinary System
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
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...

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...
