Phalloplasty with Urethral Lengthening
Urethral lengthening, usually shortened to UL, is the part of phalloplasty that builds a urethra from your existing opening, through the perineum (the skin between the genitals and the anus) and the full length of the new phallus, to the tip. It is what makes standing to pee possible. Without it the phallus is still a phallus, but you pee from an opening left at the base, sitting down.
It is the stage you can skip, and the one that causes most of the trouble. Fistulas (leaks) and strictures (narrowings) are common enough that they are better planned for than hoped against. A good share of people need a revision or two before the urethra works reliably. Surgeons build the phallus itself with fairly predictable results now. The urethra is where phalloplasty still goes wrong.
That is why this page exists on its own. Of the people I have walked through phalloplasty, the ones who had the hardest year were nearly all having urethral problems, not flap problems. Almost none of them had understood going in that this was a separate decision.

Who it’s for
People having phalloplasty for whom standing to pee is a need rather than a nice-to-have, who have looked at the complication rate and decided it is worth it. Nearly every surgeon requires a vaginectomy. The lower section of the new urethra runs through the space where the vagina was, and the closed tissue is what supports it.
The flap matters. A thin flap like RFF makes a good urethra from its own skin. Thicker flaps such as ALT often need a second flap or graft for the shaft section. With an abdominal phallus most surgeons will not lengthen the urethra at all. A history of urethral problems, poorly controlled diabetes or smoking all push the fistula risk up, and some surgeons will decline on that basis.
Skipping it is a real choice, and a minority of people make it. If sitting to pee does not bother you, or you would rather have the lowest-risk path to a phallus, the urethra can be left out. Nicotine is stopped for several weeks either side of every stage. See eligibility.

Before you book
Spend a week noticing every time you pee. Ask yourself honestly whether sitting bothers you, or whether you just assumed standing was part of the package. The answer decides whether the riskiest part of phalloplasty is worth it to you.
How it’s done
The new urethra has two sections. The lower one, sometimes called the pars fixa, runs from your existing urethral opening to the base of the phallus. The surgeon builds it as a tube from the inner labia and the lining of the vaginal entrance. That tube is joined to the existing urethra and brought forward through the closed vaginectomy tissue to the perineum.
The upper section runs the length of the shaft. With a thin flap the surgeon rolls a strip along one edge of the flap inwards into a tube, then rolls the rest of the flap around it. That is the tube-within-a-tube design. With a thicker flap the shaft urethra is made from a second, thinner flap.
Or it is made from a graft of skin or of the lining from inside the cheek (buccal mucosa), laid in flat and formed into a tube at a later stage. Whatever the source, the shaft skin that becomes urethra has to be cleared of hair beforehand, over months of electrolysis or laser.
The two sections meet at the base of the phallus. That join is the most fistula-prone point in the whole operation, and it is where surgeons differ. Some complete it in stage one. Others build both sections but leave the join for a second stage months later, once the flap's blood supply has settled.
A catheter in the urethra, and usually a second one draining the bladder through the lower abdomen (a suprapubic catheter), then stays in for three to four weeks. Before you are allowed to pee through the new urethra, an X-ray with dye run through the tube checks that nothing is leaking.

The week before
Practise moving around with a catheter bag strapped to your leg, or at least look at how one attaches. You'll be living with one for the best part of a month. Knowing how to empty it and sleep with it takes some of the strangeness out of the first days.
Urethral lengthening recovery
The catheter runs the first month. Both tubes are uncomfortable rather than painful, and the suprapubic one is the one people forget about until it snags. Urine drains into a bag on your leg or by the bed. There is nothing to do with the new urethra except keep it clean and leave it alone.
Then the leak X-ray, the catheter coming out, and the first attempt at peeing through the phallus. That milestone arrives with more nerves than most people expect. Early on the stream sprays, splits or dribbles afterwards, and that is normal. Fistulas tend to show up in the first few weeks as urine appearing somewhere it should not, along the shaft or at the perineum. Strictures come later, as a stream that weakens over months.
| Days 0–3 | In hospital with the phalloplasty stage. Urethral and suprapubic catheters in place. |
|---|---|
| Weeks 1–3 | Home with the catheters. Leg bag by day, bedside bag at night. Nothing passes through the new urethra. |
| Weeks 3–4 | Contrast X-ray. If nothing leaks, catheters out and first pee through the phallus. Spraying and dribbling normal. |
| Weeks 4–8 | Any early fistula usually declares itself. Small ones may close with the bladder drained again for a while. |
| Months 3–6 | Stream settling. Flow tests at follow-up. Stricture repair or fistula revision planned if needed. |
| Months 6–12 | A reliable stream for most people, sometimes after a revision. Glansplasty can go ahead; an erectile implant waits until the urethra is stable. |

In the first month
Keep a pair of dark, loose trousers and a spare pad by the door once the catheter is out. If a fistula shows up it will be as a damp patch at the wrong moment. Being ready for that is easier than being embarrassed by it.
Urethral lengthening scars
None that belong to the urethra alone. The work is inside the phallus and along the perineum, and the perineal closure sits in the same line as the vaginectomy and scrotoplasty scars. What you see on the phallus is the seam of the flap, which is there whether or not a urethra runs inside it. A fistula repair or stricture revision adds a small scar on the shaft or underside wherever the surgeon opens it.
Sensation after urethral lengthening
Urethral lengthening does not change sensation in the phallus. Erotic feeling comes from the buried clitoris and tactile feeling from the flap's nerves, and neither is touched by building the tube. The tissue taken from the inner labia for the lower section is not tissue you will miss.
What people do notice is the sensation of peeing through it. A new urethra has no feedback at first, so the stream starts and stops without the warning you are used to. It can take months before you sense when the bladder has emptied. That settles as the nerves grow in.
Risks and complications
Fistula and stricture are the defining risks, and they are why this stage has its own page. A urethral fistula is a hole that lets urine out somewhere other than the tip, most often at the join between the two sections. A urethral stricture is a narrowing that slows or blocks the stream.
Combined rates in published phalloplasty series run from around a quarter to a half. It depends on the flap, whether the join was staged, and how the surgeon counts. Metoidioplasty urethras do better; phalloplasty urethras are longer and built from moved tissue, and they leak and narrow more.
Most fistulas and strictures are fixable. The fix is another procedure, sometimes two, and each carries its own smaller chance of the same problem. A diverticulum, a pouch in the urethra that traps urine, can form and cause dribbling or infection. Hair left in the shaft skin grows inside the tube and collects stones.
Urinary infections are more common than before, especially early. In a small minority the urethra never becomes reliable and is abandoned, with the opening moved back to the perineum. That is safe and leaves the phallus intact, but it is the outcome to have in mind before you choose this.
Urethral lengthening results
Most people who complete urethral lengthening end up able to stand to pee. Getting there can take a year and a revision or two, and the stream is often weaker, wider or less controlled than a cis man's. The people who are happiest with it are the ones who wanted the function, not the ones who took it because it was on the menu.
What disappoints is time. The phallus is finished long before the urethra is trustworthy. Living with a fistula while waiting for the tissue to settle enough for a repair is the part of the whole pathway people describe as most wearing.
Alternatives to urethral lengthening
The alternative is phalloplasty without a urethra. The phallus is built the same way, the existing opening stays at the base, and you sit to pee. It removes most of the complication risk from phalloplasty and shortens the catheter period to days.
If you are unsure, I would say build the phallus without it and decide later. Adding a urethra afterwards is a harder operation with the flap already healed, so it is not a free option. A minority of surgeons decline to add one later at all.
The other route is abdominal phalloplasty, which has no urethra by design and the lowest complication rate of any flap. And metoidioplasty with urethral lengthening gets standing to pee with a shorter urethra and a lower fistula rate, at the cost of size.
Combining urethral lengthening with other surgery
The lower section is nearly always built in stage one, alongside the phallus, the vaginectomy and often a scrotoplasty. Whether the join is made then or left for a later stage is the surgeon's protocol, and both are common. Glansplasty and erectile implants wait until the urethra is stable, because an implant next to a leaking urethra is an infection waiting to happen. See surgery order.
Urethral lengthening cost
When the urethra is built as part of a phalloplasty stage it is in the stage price and not itemised. The figures that land on their own are for a delayed join, a fistula repair or a stricture revision. Those are the bills people do not budget for. Ask what the quote says about revisions. Some surgeons include one urethral repair in the package; most do not, and some charge full theatre fees for it.
Insurance in the US generally authorises each stage separately. A revision is a fresh authorisation, and a fresh out-of-pocket amount if it lands in a new plan year. Abroad, a repair means another trip.
| Country | Self-pay | Public / insurance |
|---|---|---|
| United States Included in the stage price when done with the phalloplasty; fistula and stricture repairs at the lower end | $10,000–$25,000 as a separate stage or revision | Usually covered under the phalloplasty approval; revisions need their own authorisation |
| Thailand Normally within the phalloplasty package; a repair means a return trip, so ask what the package includes | $4,000–$10,000 as a separate stage or revision | Self-pay only for international patients |
Choosing a urethral lengthening surgeon
This is the part of phalloplasty where the surgeon's numbers matter most, because the flap outcomes between experienced surgeons are closer than their urethral outcomes. The two figures I would ask for are their fistula rate and their stricture rate, separately, for your flap. Then what those look like after the first repair. Expect numbers. A surgeon who has to look them up, or answers "very low", has not been counting.
Then ask how they handle a fistula when one appears. A surgeon who has a routine for fistulas has seen plenty, and that is what you want. Finally, ask what happens if the urethra does not work out, and whether they would help you go back to a perineal opening. Nobody likes that question, but the answer tells you a lot.

At the consultation
Ask "do you join the urethra in stage one or later?" and then ask for the fistula rate that goes with their answer. A surgeon who has thought about the join has thought about the thing most likely to go wrong.
Frequently asked questions
Can I stand to pee without urethral lengthening?
Not through the phallus. The opening stays at the base and most people sit, though some manage with a stand-to-pee device held against it. See alternatives.
How likely is a fistula or stricture?
Common enough to plan for. Published series put the combined rate at roughly a quarter to a half, most of it fixable with another procedure. See risks.
Can I add it later if I skip it now?
Sometimes. Some surgeons will build a urethra into a healed phallus, but it is a harder operation with a higher failure rate, and others decline. See alternatives.
Why do I need a vaginectomy for it?
The lower section of the urethra runs through where the vagina was, and the closed tissue supports it. Almost no surgeon lengthens the urethra over an open canal. See how it's done.
