Blood-based injections offer new hope for women with bladder leaks

This study tested two injections made from a woman's own blood (platelet-rich plasma and platelet-rich fibrin) to treat stress urinary incontinence—leaking urine when coughing, sneezing, or exercising. Forty women aged 30-75 who could not or did not want surgery received one of the two injections around the urethra. The goal was to see which injection better reduced leakage and improved quality of life, and whether repeat injections were needed.
