Lower Urinary Tract Symptoms
|June 9, 2020
Summary
Bladder neck dysfunction (BND) affects 12.3% of women with voiding issues. Video-urodynamic study (VUDS) is key for diagnosis, and treatments like alpha-blockers can improve outcomes.
Area of Science:
- Urology
- Female Lower Urinary Tract Symptoms
- Urodynamics
Background:
- Voiding dysfunction in women is a common condition.
- Bladder neck dysfunction (BND) is a recognized cause of voiding difficulties.
- Accurate diagnosis is crucial for effective treatment.
Purpose of the Study:
- To investigate bladder neck dysfunction (BND) in women with voiding dysfunction using video-urodynamic study (VUDS).
- To analyze the therapeutic outcomes for different subtypes of BND.
- To compare BND characteristics with other causes of bladder outlet obstruction.
Main Methods:
- Retrospective review of women undergoing VUDS for voiding dysfunction.
- Diagnosis of BND based on non-funneling bladder neck and/or high detrusor pressure.
- Comparison of urodynamic parameters between BND, dysfunctional voiding (DV), and other bladder outlet obstructions (BOO).
Main Results:
- BND was identified in 12.3% of women with bladder outlet dysfunction.
- BND patients showed smaller bladder filling volumes and higher bladder outlet obstruction index (BOOI).
- Alpha-blocker therapy and transurethral incision of the bladder neck improved uroflow parameters in BND patients.
Conclusions:
- BND is a significant contributor to voiding dysfunction in women.
- High-pressure BND may indicate anatomical obstruction, while low-pressure BND might impair detrusor contractility.
- VUDS is the primary diagnostic method for BND in women.

2.2K
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...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

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...

01:23Urinary Bladder
2.7K
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...

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...

The genitourinary system maintains the body's fluid balance, waste excretion, and overall homeostasis. Proper assessment is essential for early detection of disorders, with percussion and auscultation integral to this evaluation. These methods help identify signs of kidney or bladder issues and provide important diagnostic clues.Percussion for Kidney TendernessPercussion is used to assess tenderness and detect kidney and bladder abnormalities. A common method for determining kidney tenderness...
