Urethroplasty

Urethroplasty is an operation to repair a narrowed, scarred section of the urethra, the tube that carries urine out. The surgeon either cuts out a short scar and rejoins the healthy ends, or widens a longer scar with a graft taken from the inside of your cheek.

Also called urethral reconstruction, urethral stricture surgery, stricture repair, buccal mucosa graft urethroplasty, BMG urethroplasty, excision and primary anastomosis, EPA, anastomotic urethroplasty

Overview

A urethral stricture is a section of scar tissue that narrows the urethra. Urine has to squeeze through, so the stream becomes weak, slow or split, and it can take a long time to empty. Some men get repeated infections or suddenly cannot pass urine at all. Strictures can follow an injury, a catheter or scope, an infection, or a skin condition called lichen sclerosus, but often no cause is found.

Stretching the scar (dilation) or cutting it from the inside (urethrotomy) can help for a while, especially for a first, short stricture. When a stricture comes back, those treatments work less well each time. Urethroplasty rebuilds the urethra through an incision and gives the best chance of a lasting cure.

The operation is planned around the length and location of the scar. For a short scar in the bulbar urethra (the part behind the scrotum), the surgeon can often cut out the scarred piece and sew the healthy ends back together. This is called excision and primary anastomosis. For a longer scar, the surgeon opens the narrow section lengthwise and sews in a patch of lining taken from the inside of your cheek, called a buccal mucosa graft. Cheek lining is used because it is tough, comfortable being wet, and heals well in its new home.

Urethroplasty is a specialized operation, and results are best with a surgeon who does it regularly. For strictures in the bulbar urethra, success rates of about 8 to 9 in 10 or better are typical.

The parts of your body involved

The urethra runs from the bladder through the prostate and past the sphincter muscle, then through the bulbar urethra behind the scrotum and along the penis to the tip. The part from the sphincter to the tip is called the anterior urethra, and this is where most strictures form. It is wrapped in a spongy layer of tissue (the corpus spongiosum) with a rich blood supply, which helps grafts and repairs heal.

  • Bladder

    Stores urine. Years of pushing against a stricture can thicken its wall.

  • Prostate and sphincter

    Above the stricture. Repairs of the anterior urethra stay below the sphincter, so new leakage afterward is uncommon.

  • Bulbar urethra

    The section behind the scrotum. It is the most common place for strictures, and repairs here have the best results.

  • Penile urethra

    The section inside the penis. Strictures here are often longer, may be linked to lichen sclerosus or earlier hypospadias surgery, and sometimes need a repair done in two stages.

  • Inner cheek

    The moist lining inside the cheek (buccal mucosa). A strip of it is used as a patch when the scar is too long to cut out.

Why it’s done

Urethroplasty is usually recommended when a stricture keeps coming back, or when it is too long or complex for stretching or cutting to last.

  • A stricture that came back

    AUA guidelines recommend offering urethroplasty, rather than repeated cutting or stretching, when a stricture returns.

  • A long stricture

    Scars longer than about 2 cm (under an inch), or in more than one place, rarely stay open after cutting or stretching.

  • Penile strictures and lichen sclerosus

    These rarely respond for long to cutting or stretching and usually need a graft repair.

  • Injury to the urethra

    Strictures after a straddle injury, or a torn urethra after a pelvic fracture, are repaired with forms of this surgery.

  • Problems caused by the blockage

    Being unable to pee, repeated urinary infections, bladder stones, or a bladder that no longer empties well.

  • Ending repeated procedures

    Many men are tired of self-dilating or repeated trips to the operating room and want a lasting fix.

Other options

  • Urethrotomy or dilation

    Opening the scar from inside with a tiny knife or a balloon. Reasonable for a first, short bulbar stricture; less likely to last each time it is repeated.

  • Drug-coated balloon (Optilume)

    A balloon coated with a medicine that slows scar regrowth, for shorter strictures that have come back. Better results than plain stretching in a trial, with less long-term data than urethroplasty.

  • Self-dilation

    Passing a soft catheter yourself on a regular schedule to keep the scar from closing. It can keep the urethra open, but only for as long as you keep doing it.

  • Suprapubic catheter

    A tube through the lower belly into the bladder bypasses the urethra completely. An option for men who cannot have, or prefer not to have, reconstruction.

  • Perineal urethrostomy

    A new opening for urine is made between the scrotum and anus, so you sit to pee. Used for very long or complex strictures, or after a repair that did not work.

  • Watching

    If your stream is only mildly slow, you empty well, and you have no infections, regular check-ups are reasonable.

In the operating room, step by step

Press play or pick a step. Each drawing shows what your surgeon is doing at that moment. Your team may do some steps differently.

YouAnesthesia team
1 / 9

1. Going to sleep

You have general anesthesia and receive antibiotics through an IV. If a cheek graft is planned, the breathing tube is often placed through the nose so the mouth is free.

  1. You have general anesthesia and receive antibiotics through an IV. If a cheek graft is planned, the breathing tube is often placed through the nose so the mouth is free.

  2. Your legs are raised in well-padded stirrups so the surgeon can reach the area between the scrotum and anus. The team pads pressure points carefully and checks your legs during the operation, because long periods in this position can strain nerves and muscles.

  3. If a graft is needed, the surgeon, or a second surgeon at your head, removes a strip of lining from the inside of one cheek. It is usually about 2 cm wide and as long as the scar requires, often 4 to 6 cm (1.5 to 2.5 inches). The cheek is closed with dissolving stitches or left to heal on its own.

    More detail

    The surgeon stays clear of the small opening of the saliva duct, which sits in the cheek near the upper back teeth. Some teams take the graft at the start of the operation; others wait until the scar has been measured.

  4. A thin scope is passed into the urethra up to the scar to see where it starts.

  5. For a bulbar stricture, a vertical incision about 2 to 3 inches long is made behind the scrotum. The muscle covering the urethra is opened, and the urethra is freed from the tissue around it. For a penile stricture, the incision is usually on the underside of the penis.

  6. The surgeon locates the scar, often by passing a soft probe up to it. The urethra is opened lengthwise through the narrow segment until healthy, wide urethra is reached at both ends. Now the true length of the scar can be measured.

  7. If the scar is short, usually under about 2 to 3 cm (about an inch), the scarred piece is cut out completely. The two healthy ends are trimmed, freed enough to meet without tension, and stitched together over a catheter.

    More detail

    The bulbar urethra is elastic and can stretch a little to bridge the gap. Some surgeons use a technique that removes the scar without fully dividing the spongy tissue around it, to keep more of its blood supply.

  8. If the scar is longer, it is left in place but opened lengthwise. The cheek graft is laid into the opening as a patch and stitched in place, which makes the channel wide again. The graft is spread flat on a bed of healthy tissue that will grow new blood vessels into it.

    More detail

    The graft can go on the top side of the urethra (dorsal onlay), the underside (ventral onlay), or both. The best position depends on where the scar is and the surgeon's preference; results are similar.

  9. A soft catheter is passed through the repair into the bladder. It acts as a splint and drains urine while the repair heals. The muscle and skin are closed in layers with dissolving stitches. Some surgeons also place a small drain or a tube through the lower belly.

After the operation

Right afterward

  • Waking up

    You wake up with a catheter, soreness between the legs, and, if a graft was taken, a sore, swollen cheek.

  • Mouth care

    Ice chips and cold drinks help the cheek. You can usually start soft foods the same day.

  • Leg checks

    Nurses check the feeling and movement in your legs, because of the time spent in stirrups.

  • Pain and spasm medicine

    Acetaminophen and an anti-inflammatory if safe for you, a few stronger tablets, and often a medicine for bladder spasms.

  • Catheter teaching

    A nurse shows you how to switch between the leg bag and the night bag and how to keep the catheter secured.

  • Going home

    Many men go home the same day or the next morning, with the catheter in place.

At home

  • Catheter care

    Keep the catheter taped or strapped to your thigh so it does not tug. Clean where it enters the penis with soap and water daily. Do not let anyone except your urology team remove or replace it.

  • Bladder spasms

    Sudden cramps with urine leaking around the catheter are common. Spasm medicine helps, and they ease once the catheter is out.

  • Your mouth

    Eat soft, cool foods for several days and avoid spicy, salty or crunchy foods. Rinse with salt water or the prescribed rinse after meals. Most men eat normally within 1 to 2 weeks.

  • Wound and swelling

    Bruising and swelling of the scrotum and perineum are common. Ice for 20 minutes at a time in the first 2 days and snug briefs help. Shower after 24 to 48 hours; avoid baths until your surgeon says the incision has healed.

  • Sitting

    Sitting on the incision is sore at first. A soft cushion or sitting slightly to one side helps. Avoid bicycles and other straddle seats for about 6 weeks or as your surgeon advises.

  • Activity and lifting

    Walk every day. Avoid lifting more than about 10 to 15 pounds, straining and hard exercise for about 6 weeks.

  • Bowels

    Pain medicine can cause constipation. Drink plenty of fluids and use a stool softener so you do not strain.

  • Driving

    Do not drive while taking opioid pain medicine. Many men drive within 1 to 2 weeks once sitting is comfortable.

  • Sex

    No sexual activity until the catheter is out and your surgeon clears you, usually about 4 to 6 weeks. Night-time erections with the catheter in can be uncomfortable; this is expected.

  • Work

    Desk work is often possible within 1 to 2 weeks, even with the catheter. Heavy work usually waits 4 to 6 weeks.

Recovery timeline

  1. Day 0
    Surgery

    The repair is done, and many men go home the same day or the next morning.

  2. Days 1 to 5
    Home with a catheter

    The cheek is most sore on days 2 to 4. Perineal soreness and bladder spasms are common.

  3. Weeks 1 to 2
    Mouth heals

    Most men are eating normally and getting around comfortably, still with the catheter.

  4. Weeks 2 to 3
    X-ray check and catheter out

    An X-ray dye test checks that the repair has healed without leaks. If it has, the catheter comes out. If there is a small leak, the catheter stays about another week.

  5. Weeks 3 to 6
    Back to normal

    Your stream is usually strong. Most men return to full activity and sex by about 6 weeks.

  6. About 3 months
    First check-up

    A urine flow test, a bladder scan after you pee, and a review of symptoms.

  7. 1 year
    Further check

    Most strictures that come back do so within the first 1 to 2 years, so follow-up continues during this time.

  8. Long term
    Watching your stream

    If your stream slows again at any time, see your urologist early.

What it feels like

Men usually say the catheter weeks are the hardest part. The pain of the operation itself is often less than expected, and the moment a strong stream returns is a big relief, especially for men who have struggled for years.

  1. Before surgery

    Many men are tired of a weak stream and earlier procedures, and uneasy about the cheek graft and weeks with a catheter.

    What helpsAsk your surgeon to show you the X-ray of your stricture and walk you through the plan. Knowing exactly what will happen makes it easier.

  2. Waking up

    The cheek can bother you more than the incision between the legs. Your mouth may feel tight and swollen, and your lip or cheek may feel numb.

    What helpsIce chips, cold drinks and pain medicine on a schedule.

  3. Eating in the first days

    Chewing is sore, and hot, spicy or crunchy food stings.

    What helpsSoft, cool foods. Chew on the other side. Most men are eating normally within 1 to 2 weeks.

  4. Living with the catheter

    Embarrassment, the tug of the tube, bladder spasms, and uncomfortable erections at night.

    What helpsSecure the tube to your thigh, wear the leg bag under loose pants, take spasm medicine as directed, and empty the bag before it gets heavy.

  5. Sitting

    Sitting on the incision feels like sitting on a deep bruise.

    What helpsUse a soft cushion, shift your weight to one side, and get up and walk often.

  6. Catheter removal day

    Nervous waiting for the X-ray result, then the first pee may sting or spray.

    What helpsDrink normally. The first few pees settle quickly, and many men are amazed at how strong the stream is.

  7. The following weeks

    Some men notice a few drops of urine after they finish, or a change in sensation or feel during erections.

    What helpsPressing gently behind the scrotum and sweeping forward after peeing clears the last drops. Most changes ease over months.

How well it works

Success means a strong stream that stays strong without further procedures.

  • Success rates

    For short bulbar strictures that are cut out and rejoined, about 9 in 10 men or more stay open over the long term. With cheek grafts, about 8 to 9 in 10 are successful at several years. Results are lower for long penile strictures, lichen sclerosus, and repairs after radiation.

  • How success is checked

    Your symptoms, a urine flow test and a bladder scan after you pee. If anything looks off, a cystoscopy or X-ray dye test.

  • If the stricture returns

    Most recurrences show up in the first 1 to 2 years, often as a thin ring that can be treated with a minor procedure.

  • Long-term follow-up

    Any time your stream slows again, tell your urologist early, when treatment is simplest.

Risks

Every operation has risks. These are the ones people ask about most, with honest odds where good numbers exist. Your surgeon’s own results matter more than averages.

Common

Mouth soreness and swelling

Expected for 1 to 2 weeks when a cheek graft is used.

Swelling and bruising

Between the legs and in the scrotum for 1 to 2 weeks.

Bladder spasms

Common while the catheter is in.

Dribbling after urinating

A few drops after you finish are common after bulbar repairs. Usually mild, and helped by pressing behind the scrotum.

Less common

The stricture comes backAbout 1 in 10 men after bulbar repair; more often for long or penile strictures

Often a thin ring that can be treated with a minor procedure; sometimes another urethroplasty is needed.

Changes in erections

Some men notice softer erections, a slight change in curve or length, or less feeling in the head of the penis for some months, especially after the scar is cut out. Most improve within 6 to 12 months.

A small leak on the X-ray

The catheter stays in a little longer, and nearly all such leaks heal.

Numbness or tightness in the cheek

Usually improves over a few months.

Infection

A urinary or wound infection, treated with antibiotics.

Numbness or tingling in the legs

From the surgical position. Usually temporary.

Rare

Lasting erection problems

Uncommon. Ask your surgeon about your specific risk.

Pressure injury to leg muscles

A rare but serious problem after long surgery in stirrups, called compartment syndrome. Teams limit time in the position and watch for it.

Problems opening the mouth or with the saliva duct

Rare after cheek graft harvest.

Blood clots

Rare. Walking soon after surgery lowers the risk.

Call your care team or go to the emergency room if

  • Fever of 101°F (38.3°C) or higher, or shaking chills
  • The catheter falls out, or stops draining and your bladder feels full. Call your urology team right away, and do not let anyone else put a new one in
  • Heavy bleeding from the penis or incision, or swelling of the scrotum or perineum that grows quickly and feels tense
  • Redness, warmth or pus at the incision
  • Leg pain, swelling, numbness or weakness that is getting worse
  • Mouth bleeding that does not stop after 20 minutes of firm pressure, or swelling that makes it hard to swallow
  • Chest pain or trouble breathing (call 911)

Questions to ask your surgeon

  1. How long is my stricture, and exactly where is it?
  2. Will you cut out the scar and rejoin the ends, or use a graft?
  3. Will you need a cheek graft, and from which side?
  4. How many urethroplasties do you do each year?
  5. What success rate do you see for strictures like mine?
  6. Should I stop self-dilating before surgery, and for how long?
  7. How long will I have the catheter, and how will you check healing?
  8. What are the chances of changes in erections or penis length?
  9. Does lichen sclerosus play a part, and does it need treatment?
  10. If the stricture comes back, what are my options?
  11. When can I ride a bicycle, return to work and have sex?

Common questions

Why use the inside of my cheek?

Cheek lining is tough, used to being wet, easy to take, and heals well when moved to the urethra. The cheek itself heals in 1 to 2 weeks.

Will my face look different?

No. The graft comes from inside the cheek, and there is no scar on the face. Some men notice tightness or numbness inside the cheek for a few months.

Why do I need a catheter for so long?

The catheter supports the repair and keeps urine away from it while it heals. Removing it too early could let urine leak and cause the scar to return.

I have had several urethrotomies. Is it too late?

No. Urethroplasty still works well after earlier procedures, although repeated cutting can make the scar longer and the repair more involved.

Will this affect my erections?

Some men notice changes in firmness, curve or sensation for several months, and most recover. Lasting new erection problems are uncommon.

Do I need to keep self-dilating after surgery?

Usually not. Most surgeons ask you to stop once the repair has healed, unless they advise otherwise.

Can the stricture come back after urethroplasty?

Yes, in a minority of men, most often in the first 1 to 2 years. Many of these are thin rings that can be treated with a small procedure.
