Great question. Although the urethra is continuous from the bladder to the tip of the penis inside the prostate its more of just a lining. Picture it as a carpet overlying the prostate gland. When you resect it, yes, you are removing the urethral lining. It starts to reline itself within days and eventually has a complete new lining. Like removing carpet, lowering the floor, then laying in new carpet.

pain after vasectomy

The bumps on the penis are probably pearly papules since you have never had sex. The bump on the testicle needs to get checked by a doctor. Testicular cancer is the most common solid tumor in young men. You may need an ultrasound. On a positive note, if it moves around and is not attached to the testicle it is probably just your epididymis. Please get checked. RSN

UTI? Kidney Stones? Anxiety??

If you had symptoms in November and had a negative CT scan it's unlikely the symptoms you're having now are from a stone. Stones can form fast but are still unlikely. Problem is that a CT with contrast can miss small stones because the contrast is white and stones are white on CT. If blood is in the urine it's possible. More likely cystitis. Check into a test by a company called Pathnostics. It checks PCR for a lot of microorganisms that may not grow out on culture.

Urinary issues?

That's easy. Get a 2nd opinion. You probably were living close to the edge and something tipped you over. Once your bladder stretched out, you're on the "other side" of the edge and struggling. You likely will need long-term medication (you're on 2 of the big 3 we use). The 3rd med you could use is Cialis 5 mg daily. If a patient doesn't want to be on meds then I'd look in and see the configuration of the prostate. Options depending on size and configuration include TURP (laser or regular), UroLift, Rezum, etc. UroLift is the only treatment without sexual side effect. If it was me, I'd probably try the combination of tamsulosin and Cialis and see if that'9s better. If not, seek treatment.

Foreskin issue?

That’s pretty normal. It might pose a problem as you get older, diabetic, or heavier. Consider a circumcision if it ever is a real bother.

Why boyfriend won't wear condoms?

There is a condom for every size and condition. He’s obviously not trying hard enough.

Don't do anything different if it's just a post-void residual. They will ask you to urinate and then measure how much is left with an ultrasound. If you over drink, sometimes your bladder will be stretched out and it won't be accurate.

Why do I have delayed ejaculation?

Anti-depressant medication is the number 1 reason. Diabetes can also be a cause.

How to clear a fungal infection on your penis?

Usually, we use a combination of steroid and anti-fungal such as triamcinolone and nystatin. If this doesn’t work, sometimes you end up needing a circumcision. Roscoe S. Nelson, READ MORE

Can I get a UTI from this?

It would be very unlikely to "catch" a standard UTI from your girlfriend. There are some vaginal infections (STIs, yeast, etc.) that can be transmitted. Thanks, Roscoe S. READ MORE

Do I have a urinary tract infection?

Probably. It could be something worse, but at 21, the most likely diagnosis is a UTI of some sort. See a doctor as you will need antibiotics.
