I had an enlarged prostate and was urinating blood so a foley was inserted blood stopped after 2 days and i removed folry after 7 days ..I tried for 24 hours to urinate to no success so a new foley was inserted 3 qts of urine came out and now i have to wait 7 days till i try again ..im 57 yr 6'2" 220 lbs and am taking 100mg atenol for HBP and flomax .4 and proscar 5mg it was very painful when the foley went by my prostate which might be the cause of my failure on urinate
