Summary
This study details a rare coronal plane urethral duplication in a child with enuresis. This unique finding aids in diagnosing and planning treatment for this rare congenital anomaly.
Area of Science:
- Pediatric Urology
- Congenital Anomalies
- Medical Imaging
Background:
- Urethral duplication is a rare congenital anomaly.
- Most urethral duplications occur in the sagittal plane.
- Primary enuresis can be a presenting symptom.
Observation:
- An isolated urethral duplication was identified in the coronal plane.
- The patient presented with primary enuresis.
- This presentation is atypical for urethral duplication.
Findings:
- Magnetic resonance imaging (MRI) is effective in delineating urethral duplication.
- Catheterization of the distal opening aids in diagnosis.
- Coronal plane duplication presents unique diagnostic challenges.
Implications:
- Accurate delineation enables individualized treatment strategies.
- Understanding rare anatomical variations is crucial for pediatric urologists.
- Early diagnosis and intervention can improve patient outcomes.

01:22Ureters
1.1K
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...

229
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

01:19Anatomy of the Genitourinary System II: Bladder and Urethra
685
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
2.7K
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...

1.8K
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

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...
