Perineal Urethrostomy Explained

Perineal Urethrostomy Explained

📖 7 min read Written/reviewed by Dr. Alhad Naragude, MBBS, MS, DrNB Urology Last updated: September 4, 2026

Perineal urethrostomy is a reconstructive operation that creates a new permanent urinary opening in the perineum, usually using healthy bulbar urethra. Urine then exits through this opening rather than through the penile urethra, so the patient generally sits to urinate. It is an established treatment—not a “last-resort failure”—for complex anterior urethral stricture, panurethral disease, multiple failed reconstructions or patients who prefer a simpler durable outlet instead of extensive penile reconstruction.

Who may benefit from perineal urethrostomy?

  • Complex or long anterior urethral stricture.
  • Panurethral stricture with a healthy proximal bulbar urethra.
  • Multiple failed urethroplasties.
  • Severe lichen sclerosus or failed hypospadias where further penile reconstruction is undesirable.
  • Significant medical comorbidity making long complex reconstruction less attractive.
  • A patient who prioritises reliable voiding and is comfortable sitting to urinate.

What happens during the operation?

Through a perineal incision, the bulbar urethra is opened and sutured to perineal skin to create a wide, well-supported stoma. Several surgical designs exist; the surgeon selects one according to body habitus, scar extent and the location of healthy urethra.

Will urine still come from the penis?

No meaningful urinary stream should pass through the diseased distal urethra once a definitive perineal urethrostomy is functioning. Urine exits from the perineal opening. Semen may still travel through the urethra depending on anatomy, but ejaculation and fertility considerations should be discussed individually.

How does it affect daily life?

Issue What to expect
Urination Usually sitting, through the perineal opening.
Catheter Short-term catheter while the stoma heals.
Sexual activity Erections and penile sensation are generally preserved; urinary route changes.
Clothing Usually no special clothing once healed.
Stoma care Routine hygiene and awareness of narrowing/skin irritation.
Future catheterisation Access is through the perineal opening.

Advantages

  • Can avoid a long or multi-stage penile reconstruction.
  • Provides a wide urinary outlet in difficult disease.
  • Usually no oral graft is required for standard cases.
  • Can be particularly valuable after multiple failed repairs.

Limitations and risks

  • Permanent change in the site of urination.
  • Stomal narrowing/stenosis.
  • Bleeding, infection or wound problems.
  • Spraying or post-void dribbling.
  • Need for revision if the opening contracts.

Is it reversible?

Sometimes further urethral reconstruction is technically possible, but perineal urethrostomy is usually chosen as a durable endpoint rather than a temporary diversion. The decision should therefore be made with the expectation that the perineal opening may be permanent.

Perineal urethrostomy is a reconstructive choice, not merely a last resort

Perineal urethrostomy creates a permanent urinary opening in the perineum using healthy proximal urethra. The patient urinates while sitting, bypassing the scarred distal penile urethra. For selected men with extensive lichen sclerosus, panurethral disease, multiple failed reconstructions or significant comorbidity, it can provide a simpler and very durable way to empty the bladder.

The main trade-off is lifestyle rather than kidney or bladder function: urine no longer exits at the tip of the penis, so standing urination is usually not possible. Erections, orgasm and ejaculation can still occur, although semen exits through the perineal opening and fertility plans may need discussion.

The stoma itself can narrow and occasionally requires revision, particularly in scar-prone disease. Good surgical technique uses healthy urethral tissue and creates a wide, dependent opening. Patients who value reliable voiding and fewer reconstructive stages often find this option preferable to repeated attempts to rebuild a severely diseased distal urethra.

Who may benefit most from perineal urethrostomy

Perineal urethrostomy can be particularly attractive in extensive lichen sclerosus, panurethral stricture, multiple failed hypospadias repairs, recurrent penile-stricture surgery or older or frail patients who want a simpler durable outlet. It can also be used as part of a staged pathway, although many patients choose it as the definitive endpoint.

The surgeon must still select healthy urethral tissue; a stoma created within active scar can narrow. Different flap configurations can be used to create a wide mucosa-to-skin opening. Obesity, a deep perineum and ongoing inflammatory disease can make construction and later self-inspection more difficult.

After healing, no urethral catheter is usually needed long term. Patients urinate sitting through the perineal opening and should return if the stream narrows or spraying becomes difficult. A perineal urethrostomy does not remove the bladder or prostate and does not by itself eliminate erections or orgasm.

Recovery

Patients walk early but avoid pressure and heavy activity while the perineal wound heals. The catheter after a straightforward perineostomy can often be removed within several days, depending on the operation. Sitting comfort improves progressively. Your surgeon will give specific wound and hygiene instructions.

What if the opening narrows later?

Stenosis can sometimes be managed with dilatation, but significant recurrence may require surgical revision or enlargement of the stoma. Obesity, proximal scar extension and poor local tissue can influence the design and long-term outcome.

Who may prefer a perineal urethrostomy as the final solution

Perineal urethrostomy is sometimes described as a “last resort,” but that language can be misleading. For an older man with extensive lichen sclerosus, multiple failed repairs or a very long scar, it can offer a durable, low-maintenance urinary outlet without another complex penile reconstruction.

It may also suit a patient who prioritises reliable voiding over standing urination from the tip of the penis. The trade-off is that urination is through the perineal opening and is usually performed sitting down.

The decision is personal. A well-informed patient choosing perineal urethrostomy is not accepting an incomplete repair; he is choosing a different reconstructive endpoint with its own benefits and risks.

What to bring for consultation

  • RGU and MCU/VCUG images or films, not only the written report.
  • Uroflowmetry report and post-void residual if already done.
  • Urine routine and urine culture reports.
  • Serum creatinine and other relevant blood tests.
  • Previous catheter, VIU/dilatation or urethroplasty discharge summaries.
  • Details of any pelvic injury, prostate surgery, hypospadias surgery, radiation or recurrent infections.
  • Current medicines, including blood thinners, and any history of self-dilatation.

How perineal urethrostomy is created and maintained

Through a perineal incision, the healthy proximal bulbar urethra is brought to the skin and opened widely to create a new urinary meatus in the perineum. Diseased distal urethra is bypassed rather than reconstructed all the way to the glans. The opening must be broad, well vascularised and positioned so urine drains without pooling in deep folds.

A catheter is usually left temporarily while the new opening heals. Once removed, the patient urinates sitting down. Early care focuses on keeping the area clean and watching for wound infection or narrowing at the skin edge. Hair-bearing skin around the opening may occasionally need attention if it causes irritation.

The main late failure is stenosis of the urethrostomy. A progressively narrowing stream, prolonged voiding or recurrent infection should trigger review early; repeated stretching of a poorly designed or scarred opening may not be durable. Revision is possible if needed.

FAQs

Is perineal urethrostomy only for elderly patients?

No. Age alone is not the indication. It is chosen according to disease complexity, health, previous surgery and patient priorities.

Can I have intercourse normally?

The operation does not remove the penis and usually does not directly prevent erections or intercourse. Ejaculatory route and fertility depend on individual anatomy and should be discussed.

Will I be incontinent?

A standard anterior perineal urethrostomy is distal to the urinary sphincter, so continence is usually preserved if the sphincter is normal.

Do I need a bag?

No. It is not a urinary diversion into a stoma bag; you void voluntarily through the perineal opening.

Why would someone choose it over another graft urethroplasty?

For some patients, one reliable perineal outlet is preferable to multiple further penile/graft operations with uncertain durability.
