Haematuria is presence of blood in the urine. It is important to know whether it was associated with any pain, fever or urinary symptoms, signifying association with stone disease or infections. Painless causes bother us more, since these could be associated with a cancer in the urinary tract. Urine cytology, ultrasound scan, CT scan and endoscopic examination are usually done to exclude the latter causes. It seems that nothing significant was found and you were labelled as having the bleeding directly from prostate, or due to infection secondary to prostate obstruction, and hence you were advised Urimax-F. The medicine is a combination of an alpha blocker and finasteride, both working on prostate to relax and make it smaller.
Now the answers to your questions:
1. Whether the treatment should continue, and if yes, whether one or both the drugs in combination should continue: This may be decided upon the clinical picture at present, apart from the ultrasound finding of the volume of your gland and residual urine, present PSA and result of your uroflowmetry.
2. Twenty percent of patients taking tamsulosin (urimax) may experience reduced or absent ejaculate. It is not worrisome as orgasm and erectile properties remain unaffected, and this being a reversible side effect of medicine.
3. All prostate enlargements do not bleed. Your bleed, as mentioned earlier could be directly from prostate or secondary to bladder neck obstruction with prostate. In both circumstances prostate could be responsible even without increase in its bulk.
