Stricture Urethra. Or any side effects.

I have been suffering from stricture urethra since 20 years now. It started 20 years back when i was catherized. all these years i neglected but now the urine flow is in two stream, burning sensation and urge to urinate very frequently.. However i got myself checked with Urologist for which he recommeded me to undergo Urethragram. It was found out that i have a long stricture urehtra all the till bladder..and bladder distended.. it has been ruled out chronic cystisis. Since i be marrying in two months is it advisable for surgery at this stage.. will dat affect my sex life post marriage.. cos i have heard surgeries often create erectile dysfucntion at a later stage...used to get painful erections recently but it has stopped automatically.. the semen often does get blocked in an erected penis and flows out when penis goes into a flacid state. please advise.. if i need to undergo surgery or any side effects.. i am worried...
