One-Stage vs Two-Stage Urethroplasty

One-Stage vs Two-Stage Urethroplasty

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

One-stage urethroplasty completes the reconstruction in one operation; staged urethroplasty deliberately leaves the urethra open after the first operation and tubularises it months later. Neither is universally better. A one-stage oral mucosal graft repair is preferred when the urethral plate and local tissues are healthy enough. Staged repair is valuable when there is severe penile scarring, failed hypospadias, fistula, poor urethral plate or other adverse tissue. The correct choice is based more on tissue quality than on stricture length alone.

One-stage vs two-stage: quick comparison

Feature One-stage urethroplasty Staged urethroplasty
Number of planned operations One At least two; sometimes more
Best tissue setting Healthy plate / adequate vascular bed Scarred, deficient or unreliable local tissue
Common use Many bulbar, penile and panurethral graft repairs Failed hypospadias, complex penile scar, fistula, severe local damage
Catheter after definitive closure Usually 2-3 weeks Longer catheter after final tubularisation; first stage often shorter
Between operations Not applicable Patient urinates through open reconstructed plate/meatus
Ability to revise graft before closure No separate maturation stage Yes

When is one-stage reconstruction preferred?

One-stage repair avoids a prolonged treatment pathway and is appropriate when the urethral plate can be preserved/augmented, local tissue is vascular and there is no major fistula, active infection or severe scar that makes closure unreliable. Many bulbar graft urethroplasties and selected penile/panurethral repairs are performed this way.

When is staged reconstruction safer?

  • Severely scarred failed-hypospadias urethral plate.
  • Multiple prior penile operations.
  • Fistula or false passage within unhealthy tissue.
  • Need to replace poor local tissue with oral mucosa and observe graft take.
  • Severe spongiofibrosis where immediate tubularisation would be under tension or poorly vascularised.

Does lichen sclerosus automatically mean two stages?

No. In the absence of adverse local conditions, single-stage oral mucosal graft urethroplasty can achieve good outcomes in lichen sclerosus. Genital skin should generally be avoided. Staging is chosen when the local anatomy—not the diagnosis alone—makes one-stage repair unreliable.

Why a two-stage operation may become three stages

The surgeon may find graft contraction or residual scar at follow-up. Revising the first-stage plate before tubularisation can improve the chance of a durable final result. Patients should be counselled that “two-stage” describes a strategy, not a guaranteed operation count.

Which has the better success rate?

Published outcomes vary widely because staged patients are usually more complex than one-stage patients. Comparing raw percentages is therefore misleading. A simpler stricture chosen for one-stage repair is not equivalent to a multiply operated failed hypospadias chosen for staging.

What about recovery and quality of life?

One-stage repair has one major recovery and one catheter period. Staging spreads the burden across several months, and the first-stage opening changes the way urine exits during the interval. On the other hand, staging can prevent the patient from undergoing an ambitious one-stage closure that is likely to fail in poor tissue.

How the surgeon decides

  • Urethral plate width and quality.
  • Extent of penile skin scarring.
  • Presence of fistula, infection or hair-bearing tissue.
  • Lichen sclerosus or radiation.
  • Number and type of previous operations.
  • Availability of oral mucosa.
  • Patient willingness to undergo staged treatment and accept the temporary first-stage anatomy.

How a reconstructive urologist decides between one and two stages

The decision is mainly about tissue quality. A one-stage repair is attractive when a usable urethral plate remains, local tissues are well vascularised and the surgeon can create adequate calibre without excessive tension. Staged repair becomes more reliable when the plate is scarred or deficient, there is severe lichen sclerosus, extensive failed hypospadias, significant curvature or multiple prior operations.

Length matters, but it is not the only variable. A long stricture with a healthy plate can sometimes be reconstructed in one stage with oral mucosa, while a shorter segment in a scarred hypospadias penis may be safer to stage. This is one reason an experienced surgeon may change the plan after opening the urethra and directly assessing the tissue.

Patients should compare pathways rather than slogans. One-stage surgery offers one major reconstruction but may be inappropriate if it compromises graft support. Staged surgery requires a period of voiding through an open urethral plate and another operation months later, but it can provide a healthier platform in the most difficult tissue. The “better” choice is the one that fits the anatomy and the patient’s priorities.

Recovery differences between one-stage and staged repair

One-stage reconstruction concentrates the main urethral repair and catheter period into a single operation. Staged surgery distributes reconstruction over time: stage one creates the open grafted plate, the patient heals for several months, and stage two tubularises it. That makes the total calendar longer even if each individual step is manageable.

Staged repair also changes urination between operations because the urinary opening is proximal on the grafted plate. Patients need to be comfortable with this temporary anatomy and with the possibility that graft contraction may require revision before closure.

One-stage repair has its own risk: if tissue quality was overestimated, wound breakdown or recurrence can convert a hoped-for single operation into more surgery. The decision is therefore not simply convenience versus inconvenience; it is a judgment about which pathway gives the tissue the best chance to heal.

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.

FAQs

Can the plan change from one stage to two stages during surgery?

Yes. If operative findings show poor tissue that was not fully apparent on imaging, conversion to a staged approach may be safer.

Can two-stage surgery be completed faster by closing early?

Rushing before the graft is mature can increase problems. A several-month healing interval is intentional.

Is one-stage always less successful for failed hypospadias?

No. Selected failed-hypospadias cases with favourable tissue can be repaired in one stage. The challenge is choosing the correct patient.

Can I stop after stage one?

Yes in selected patients who void comfortably and accept the position/appearance of the first-stage opening.

Which option has fewer complications?

The answer depends on anatomy. One-stage avoids a second operation, but in poor tissue it may have a higher risk of fistula or recurrence. Staging accepts more treatment steps to create a safer final reconstruction.
