Optilume BPH — Prostatic Drug-Coated Balloon System
Optilume BPH combines mechanical opening of the prostatic outlet with local paclitaxel delivery. It uses an uncoated predilation catheter followed by a separate drug-coated balloon, rather than a single interchangeable urethral-stricture balloon. The BPH balloon has a paclitaxel coating density of 2.4 µg/mm².[1]
For operative selection and technique, see Optilume BPH. For the distinct anterior-urethral-stricture product and its drug evidence, see Drug-Coated Balloon Therapy.
Label and Safety
The US PMA indication is obstructive urinary symptoms associated with BPH in men aged 50 years or older. The pivotal trial enrolled men with 20–80 g prostates; this study population is separate from the wording of the labeled indication. Balloon sizing, anatomy and eligibility must follow the BPH-specific instructions.[1]
- Contraindications include active UTI, paclitaxel-related hypersensitivity, an artificial urinary sphincter or a penile prosthesis.
- Use barrier protection during sex for 30 days after treatment. Men with partners of childbearing potential should use highly effective contraception and avoid fathering a child for at least 12 months; paclitaxel has been detected in semen during follow-up, and effects on sperm and spermatogenesis are uncertain. Do not substitute the shorter counseling interval from another Optilume product.
- Hematuria, infection, dysuria and retention can occur. An office or outpatient setting does not eliminate the need for a complication and catheter plan.
- Avoid damaging or prematurely wetting the drug coating. Device preparation, hydration, inflation limits and handling after a failed inflation are governed by the full BPH instructions.[1]
PINNACLE Evidence
PINNACLE randomized 148 men: 100 to Optilume BPH and 48 to sham. Its primary comparison used the active group's one-year IPSS improvement versus the sham group's three-month improvement. The reported 11.5 versus 8.0-point change must not be presented as a contemporaneous one-year sham comparison.[2]
At two years, follow-up was limited to treated participants: 56 of 83 evaluable participants met the symptom-response definition without medical or surgical retreatment. Missing follow-up and the lack of a long-term concurrent control limit comparisons with other procedures. Favorable sexual-function findings do not establish zero ejaculatory risk or equivalence to more invasive surgery.[3]
