Urethra01:16

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...
Urologic Endoscopic Procedure: Cystoscopic Examination01:28

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...
Ureters01:22

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...
Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
Disorders of the Urinary System01:20

Disorders 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...
Anatomy of the Genitourinary System II: Bladder and Urethra01:19

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...

    Area of Science:

    • Urology
    • Female Pelvic Medicine

    Background:

    • Female urethral stricture disease is uncommon, often caused by trauma, iatrogenic factors, or inflammation leading to fibrosis.
    • Key symptoms include urinary frequency, urgency, dysuria, hesitancy, slow stream, incontinence, and recurrent UTIs.
    • Defining female bladder outlet obstruction and urethral stricture disease can be challenging.

    Purpose of the Study:

    • To summarize the understanding of female urethral stricture disease.
    • To outline diagnostic approaches and treatment modalities for this condition.

    Main Methods:

    • Diagnosis is typically based on clinical presentation, meatal assessment, and difficulty with instrumentation.
    • Ancillary tests like urodynamics, voiding urography, and cystoscopy can aid diagnosis.
    • Treatment strategies encompass conservative management (dilation), endoscopic procedures, and open surgical repair.

    Main Results:

    • The efficacy of urethral dilation for voiding dysfunction in women remains a subject of debate.
    • Various surgical techniques involving tissue flaps or grafts are available for repair.
    • Accurate diagnosis and appropriate treatment selection are crucial for managing female urethral strictures.

    Conclusions:

    • Female urethral stricture disease requires a comprehensive diagnostic approach.
    • Treatment options vary, and ongoing research is needed to clarify the effectiveness of different interventions, particularly dilation.
