How Long Does Aquablation Last?What the Long-Term Data Says

When men consider any surgical treatment for BPH, one of the first questions they ask is: Is this a permanent fix — or will I be back in a few years? It's the right question to ask. Nobody wants to go through a procedure, recovery, and disruption to their life, only to be dealing with the same symptoms again five years later.

For Aquablation, the data available is reassuring — and growing. Here's what we know about long-term outcomes, how Aquablation compares to other options, and what factors influence how durable your results will be.

What the Clinical Trials Show

Aquablation's efficacy has been studied in two landmark trials: the WATER trial (focusing on prostates 30–80 cc) and the WATER II trial (for larger prostates 80–150 cc). Both trials used the International Prostate Symptom Score (IPSS) as the primary measure of symptom improvement, along with maximum urinary flow rate (Qmax).

At the 5-year mark — the longest published follow-up data currently available — the results are compelling:

• The majority of patients maintained clinically significant symptom improvement from their baseline IPSS scores
• Urinary flow rates remained meaningfully improved compared to pre-procedure measurements
• Retreatment rates (the percentage of patients who needed additional surgery or procedures) were low — comparable to or better than leading alternatives

In practical terms: most men who have Aquablation are still experiencing the benefit of that procedure five years later without needing further intervention.

Is Aquablation Permanent?

The word "permanent" deserves some nuance in the context of BPH. Aquablation permanently removes the prostate tissue that was causing the obstruction — that tissue does not grow back. In that sense, yes, the treatment is permanent.

However, the prostate is a living organ that can continue to change over time. In a small percentage of men — particularly those with very large prostates or who are younger at the time of treatment — the remaining prostate tissue may eventually grow enough to cause symptoms again, years down the road.

This is true of virtually all BPH procedures. No surgery eliminates the possibility of future prostate growth entirely. What Aquablation offers is a durable solution with low retreatment rates and strong long-term outcomes based on the evidence currently available.

How Does It Compare to Other BPH Treatments?

Medications (alpha-blockers, 5-alpha reductase inhibitors) — These are typically the first line of treatment, but they manage symptoms rather than addressing the underlying obstruction. Many men find that medications become less effective over time, or that they simply don't want to stay on them indefinitely.

TURP — The traditional surgical gold standard. Long-term data is extensive, and TURP is effective — but it carries higher rates of ejaculatory dysfunction and has known limitations for very large prostates. Retreatment rates at 5–10 years are generally in the 5–15% range depending on the population studied.

Aquablation — Comparable durability to TURP with a significantly better profile for preserving ejaculatory function. For men with larger prostates in particular, Aquablation offers durable outcomes that traditional procedures couldn't reliably deliver.

What Factors Affect How Long Results Last?

While the procedure itself is highly reproducible, a few individual factors can influence how long results remain optimal:

• Age at time of treatment — Younger men have more years of potential prostate growth ahead of them, which can eventually affect symptoms
• Initial prostate size — Larger prostates may have more remaining tissue that could grow over decades
• Hormonal factors — Testosterone and DHT levels influence prostate growth and may affect long-term outcomes
• Adherence to follow-up — Regular check-ins allow your physician to catch any early changes before they become significant

The Bottom Line on Longevity

Based on the evidence available, Aquablation delivers durable symptom relief for the vast majority of men — with most maintaining their improvement at the 5-year mark without additional treatment. As follow-up data continues to mature, those numbers are expected to hold.

If you're weighing Aquablation against other options and longevity is one of your primary concerns, it belongs on the short list. The right conversation to have is with a specialist who can look at your specific anatomy, prostate size, age, and symptom profile — and give you an honest assessment of what to expect.
