My Dad 82yrs old has been treated for cancer urinary bladder by surgery and bcg instillation in 2008. In 2011, he developed recurrence in the neck of the bladder. TURP was also done. Following this surgery, he developed overactive bladder and has been on suprapubic catheter since then. Moreover, inspite of changing his catheter every 3 weeks, he has urinary tract infections. Kindly let me know if his overactive bladder is treatable and how to control his frequent uti.
