Platelet-rich plasma is made from a patient's own blood and contains growth factors that may help repair the lining of the bladder and improve bladder function. The second treatment uses botulinum toxin. Botulinum toxin is a protein that can reduce unwanted bladder contractions and is already approved for use in patients with overactive bladder who did not
