My father is 85 years old. He suffering from enlarged prostrate and is on catheter for micturitionfor the past 9 months. Since the last two months after consulting an urologist he is on a regular medication on flotral (1 tab daily at bed time) My query: How do I know that the medicine has worked , Or Should the catheter be removed now and let him urinate (once the catheter had come off accidentally but the outcome was dad could not hold back his urine for more than an hour .It was a pretty good volume of urine that he passed out and now hes back with the catheter > Please advise as this is becoming a problem worth giving some importance.
