Urethroplasty: Scar Tissue Repair of Urine Channel

Urethroplasty is the fixing of scar tissue in the urine channel from the bladder out the penis.  There are many surgeries possible to fix this and all work to increase the size of the urine channel to improve urine flow.

Why does scar tissue form in the urine channel?

There are many causes of this including prior injury, prior procedures such as catheter placement, prior surgery, or even sexually transmitted diseases.  A particular cause of scar formation known as Balanitis Xerotica Obliterans (BXO) can even effect a large portion of the penis both inside and out.

What problems would I have?

Anyone with a build up of scar tissue in the urine channel can have a slow urine stream or feel all the urine does not come out.  Some individuals develop a complete blockage and have no ability to urinate.  Other patients may feel pain with urination or have bladder infections.

What is done to determine if I have a blockage?

Prior to urethroplasty surgery it is important for all patients to have an x-ray test of the urethra to determine the location of the scar tissue.  Some patients may also undergo a uroflow test, urodynamics, or cystoscopy depending on the problems.

What types of repairs are available?

There are several options for fixing blockages of the urine channel.  Most scar tissue can be stretched open as a form of treatment but the scar can come back quickly with this procedure.  A camera and small scope can be used to guide a small knife to cut the scar open and usually a drainage tube is left in the penis.  In most cases this is useful for short scars or those that are new.  The longest lasting repair is urethroplasty.  In this procedure, the region of scar tissue is either removed or enlarged through a cut in the skin.  A small drainage tube (catheter) is left in place after surgery to allow the treated area to heal.

Will urethroplasty cause trouble having sex?

In general it is not likely to have trouble with sex after this surgery.  Some patients may have trouble with erections in addition to the urine channel blockage.  Both of these problems can be treated by your doctor.

Who performs a urethroplasty?

Many urologists feel confident to do the surgery but only about 10% do these surgeries often.

Does it leave a scar on the penis?

Most urethroplasty procedures are performed through the perineum, the region between the scrotum and the anus.  There are surgeries when the penis skin is used and a cut on the penis may be needed.  With care and good surgery, this rarely leads to scar tissue forming on the outside of the penis.

Does the procedure hurt?

Most people do have pain after the surgery, but the pain is usually not very bad.  Patients are given pain medication to limit the discomfort.  Some patients do not have any pain after surgery.

Catherter (drainage tube) care after surgery:

A small tube (catheter) about the size of cooked spaghetti will be placed in the penis for 10 to 20 days after surgery to allow it to heal.  The tube should be kept clean and taped to the skin to prevent movement.  A small amount of antibiotic ointment should be put daily at the penis opening to keep the catheter from sticking.


Recovery Guidelines for Urethroplasty

Most patients recover fairly quickly after the procedure but the swelling from the surgery may take weeks to get better.  In general it is recommended to limit activity to basic needs until the penis drain (catheter) is removed.  Pain should improve in the first week after surgery.
