Potential cures would depend on what is causing the prostatic bleeding (i.e. recurrance of the cancer or a mass). If the bleeding continues, there should be consideration for taking the prostate out. It may be that your husband is a poor surgical candidate (thus the urologist saying that no cure exists).
If the bleeding continues, you may want to inquire about a second urological opinion.
Another consideration would be checks for any clotting disorders (i.e. blood count and coagulation studies) that would delay any wound healing.
Followup with your personal physician is essential.
