Bulking agents can be injected into the bladder neck and urethra tissues to help close the bladder opening and reduce leaking.
Is it true that Bulking agents can be injected into the bladder neck and urethra tissues to help close the bladder opening and reduce leaking?
Yes. Injecting bulking agents into the bladder neck and urethra increases outlet resistance and mucosal coaptation, helping to reduce stress urinary incontinence and leaking.
Verdict: SUPPORTED · 5 sources for, 0 against · Last checked
The retrieved papers consistently confirm that periurethral and urethral bulking agents are utilized to increase urethral resistance and mucosal coaptation, thereby reducing stress urinary incontinence and leakage. Multiple systematic reviews and clinical studies support this mechanism and therapeutic application. Therefore, the claim is well-supported.
