Urethral Stricture, Scar Tissue

Hi Drs, I am new to this forum could any one help please.

Early this year I was having a problem with the Urine, Burning, weak flow, pain during and after urinate, not emptying bladder properly, frecurrent visits, infection, Pain lower belly, abdominal ect.

My urologist checked me and said I developed a Urethral Stricture Scar Tissue.

He said we will have to do operation to open the Urethra and remove the Stricture scar tissue.

I had my operation done in Nov 2014.
I was told that after the operation I will have to use Catheter 3x a week.
Because the scar tissue will occur again.
There is no medication for it, Using a Catheter will stop occurring it.

My urologist tells me take pain killers and live your life.
Take Viagra when or if I want to have a sex.
I do not like to take Viagra.

Could you help me please.
I am using Catheter 3x a week.
This is a problem for me.

1: When I use the Catheter I have few drops of blood.

2: Pain lower belly, bladder , Abdominal area.

3: Lower back pain.

4: week erection, impotence

Please help so I can have normal life.
Apart from this problem I have a check up every 6 months.
Everything is under control.

Help please help,

yours,

ALLAM
