Conditions

Prolonged catheterization in neurogenic bladder patients is a high risk of developing CAUTI, which causes many sequelae, including frequent recurrences, urosepsis, renal damage, and many complications caused by constant or repetitive antimicrobial use, as well as considerable economic and public health burdens. Currently, the prevention of CAUTI in neurogenic bladder patients, especially nutraceuticals, is not well elucidated and has controversial results. Proanthocyanidins (PACs), active comp
