Undergone urethral biopsy near meatus with stitches. Urinary stream has shifted 90 degrees to the left. Been 2 days since surgery. Is this permanent?

Usually not. There is the possibility of developing a urethral stricture which could cause permanent deflection of urine of obstruction to the flow. Only time will tell.
Probably not. This is probabaly some swelling and local irritation from the sutures. Too early from surgery. Don't be alarmed at this point. Wait for it to heal and reassess in few months.
