Summary
Reconstructive pelvic surgery temporarily impairs urethral afferent nerve function, increasing sensation thresholds. Women with stress urinary incontinence show altered pre-operative urethral sensation.
Area of Science:
- Urology
- Neuroscience
Background:
- Urethral neuromuscular function research predominantly examines efferent pathways.
- Understanding afferent innervation is crucial for pelvic floor disorders.
Purpose of the Study:
- To investigate changes in urethral afferent nerve function before and after reconstructive pelvic surgery (RPS).
- To compare urethral afferent innervation in women with and without stress urinary incontinence (SUI) undergoing RPS.
Main Methods:
- Current perception threshold (CPT) and urethral anal reflex (UAR) testing were performed pre- and post-operatively.
- Statistical analysis included Wilcoxon signed ranked test and Spearman's correlations.
Main Results:
- Urethral CPT thresholds significantly increased post-RPS, indicating reduced afferent nerve function.
- Pre-operative CPT thresholds were lower in women with SUI compared to continent women, suggesting heightened urethral sensation.
Conclusions:
- RPS has a short-term negative impact on urethral afferent nerve function.
- Women with SUI exhibit altered pre-operative urethral afferent nerve sensitivity.

6.6K
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...

3.6K
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
4.7K
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...

01:16Urethra
7.0K
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...

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.
