Optilume balloon
A minimally invasive option for selected urethral strictures, combining dilatation with a drug intended to reduce scar re-formation.
What Optilume is
Optilume is a drug-coated balloon used to treat urethral stricture. It works on two principles at once. The balloon dilates the narrowed segment mechanically, as a conventional dilatation would. As it does so, it delivers paclitaxel — an anti-proliferative drug — into the wall of the urethra, with the aim of interrupting the scarring process that causes conventional dilatation to fail.
The rationale is the persistent weakness of standard treatment. Dilatation and optical urethrotomy relieve symptoms immediately, but the scar re-forms in the majority of men, and each repeat procedure adds more scar tissue. Optilume is designed to address that recurrence directly.
Who it may suit
Optilume is used in carefully selected men, typically those with:
- Short bulbar strictures, generally under 3cm
- Recurrent strictures that have already been treated endoscopically, where the alternative is another dilatation
- A wish to avoid open reconstruction, or where surgery carries higher risk because of other health problems
- Strictures not caused by lichen sclerosus
It is not appropriate for very long strictures, for panurethral disease, for strictures caused by lichen sclerosus, or for men who want the most durable available result — which remains urethroplasty. It is also not used in men who are seeking to father children in the near future, given the drug involved.
Where this sits among the options
Optilume is a genuine addition to the range of treatments, not a replacement for reconstruction. Urethroplasty remains the most durable treatment for stricture disease, and I will say so plainly. Optilume is most useful for the man with a short recurrent bulbar stricture who wants to avoid open surgery, or who is not a good candidate for it. Being offered the least invasive option is not the same as being offered the best one for your stricture, and you are entitled to hear both sides.
The procedure
Optilume is performed endoscopically, under general or spinal anaesthetic, and usually as a day case. A telescope is passed into the urethra and the stricture assessed. A guidewire is placed across the narrowing, and the balloon is advanced over it and inflated for a set period to dilate the segment and deliver the drug. Some strictures are incised first. The balloon is then deflated and removed.
A catheter is left in place, typically for a few days, and removed at a follow-up appointment or by district nursing at home.
Recovery
Recovery is considerably quicker than after open reconstruction. Expect stinging on passing urine and some blood in the urine for a few days to a couple of weeks. Most men return to normal activities within a few days of the catheter coming out, and to sport and heavy activity within one to two weeks.
Follow-up includes flow rate measurement at intervals, since a falling flow rate is the earliest indication that the stricture is recurring, often before symptoms return.
Risks and considerations
Risks include urinary infection, blood in the urine, pain on passing urine, temporary retention, and recurrence of the stricture. Because paclitaxel is used, men who may wish to conceive should discuss timing and contraception, and the drug is not appropriate where fertility is an immediate priority. Longer-term data on drug-coated balloons in the urethra is still accumulating compared with the decades of evidence behind urethroplasty, and that difference should form part of your decision.
My practice
I set up and lead the Southeast London Urethral Reconstruction Team at Guy's Hospital, and specialise in all types of urethral surgery including the use of the Optilume balloon device alongside the full range of open reconstruction. Because I offer both, I have no reason to steer you towards one over the other — the recommendation follows the stricture, not the equipment.
Frequently asked
Is Optilume a permanent cure?
It is not presented as one. It aims to extend the interval before recurrence compared with conventional dilatation. For a durable, definitive result in suitable strictures, urethroplasty remains the reference standard. Follow-up flow tests are important either way.
How does it compare with a standard dilatation?
The mechanical part is similar; the difference is the drug delivered into the urethral wall, intended to reduce the scarring that causes conventional dilatation to fail so frequently. Published trial data supports better durability than standard endoscopic treatment, though follow-up is shorter than for urethroplasty.
Can I have urethroplasty later if Optilume does not work?
Yes. Having Optilume does not preclude later reconstruction. That said, every endoscopic treatment adds some scar tissue, so if you already know that reconstruction is likely to be needed eventually, it is worth discussing whether to go straight to it.
Will it affect my fertility?
Paclitaxel is an anti-proliferative drug, so if you are actively trying to conceive or plan to soon, this needs discussing before treatment and contraception advice will be given. Where fertility is an immediate priority, an alternative treatment is usually preferable.
Is it available on the NHS?
Availability varies by trust and commissioning arrangements. I can advise on what applies in your case at consultation, both privately and within the NHS pathway.
