Peri-Urethral Platelet-Rich Plasma Injections for Postmenopausal Female Stress Urinary Incontinence
Peri-Urethral Injections of Platelet-Rich Plasma in Treatment of Post-Menopausal Female Stress Urinary Incontinence
his prospective interventional study will evaluate the effectiveness and safety of peri-urethral injections of platelet-rich plasma for treating stress urinary incontinence in postmenopausal women. Platelet-rich plasma is prepared from each participant's own blood and contains concentrated platelets and growth factors that may promote tissue repair and regeneration.
Approximately 70 postmenopausal women with stress urinary incontinence will receive peri-urethral platelet-rich plasma injections once monthly for four consecutive months. Platelet-rich plasma will be injected into five sites around the urethra. Participants will be followed after treatment to assess improvement in urinary leakage and urinary symptoms, changes in urodynamic measurements, and treatment-related adverse events.
The study aims to determine whether repeated peri-urethral platelet-rich plasma injections can provide a safe and effective minimally invasive treatment option for postmenopausal women with stress urinary incontinence.

실험적: Peri-Urethral Platelet-Rich Plasma Injection
Participants will receive autologous platelet-rich plasma injections under local anesthesia.
A total of 5 milliliters of platelet-rich plasma will be administered, with 1 milliliter injected at each of five peri-urethral submucosal sites corresponding to the 12, 2, 5, 7, and 10 o'clock positions.
The injection procedure will be repeated once monthly for four consecutive months.
Routine urinary catheterization will not be required after the procedure.
|
Autologous platelet-rich plasma will be prepared from 30 to 50 milliliters of peripheral blood using a two-step centrifugation technique.
The first centrifugation will be performed at 200 × g for 20 minutes at 20 degrees Celsius, followed by a second centrifugation at 2000 × g for 20 minutes at 20 degrees Celsius.
The final 5 milliliters of platelet-rich plasma, with an expected platelet concentration approximately 2.5 to 5 times the baseline platelet concentration, will be used for peri-urethral injection.

Treatment Success Based on Global Response Assessment Score
기간: 1 month after the fourth platelet-rich plasma injection
|
Treatment response will be assessed using the Global Response Assessment score, which ranges from -3 to +3.
A score of -3 indicates markedly worse symptoms, -2 indicates moderately worse symptoms, -1 indicates mildly worse symptoms, 0 indicates no change, +1 indicates mild improvement, +2 indicates moderate improvement, and +3 indicates marked improvement.
Treatment success will be defined as a Global Response Assessment score of +2 or +3.
The result will be reported as the number and percentage of participants achieving treatment success.

Dry Rate
기간: 1, 3, and 6 months after the fourth platelet-rich plasma injection
|
Dry rate will be defined as the proportion of participants achieving complete continence without urinary leakage and without the need for pad protection.
The number and percentage of participants who are completely dry will be recorded.

Change in Stress Urinary Incontinence Severity Assessed by the Visual Analogue Scale
기간: Baseline through 6 months after the fourth platelet-rich plasma injection
|
Stress urinary incontinence severity will be assessed using a 10-point Visual Analogue Scale modified from the Stamey grading system, ranging from 0 to 10, with higher scores indicating more severe urinary incontinence.
