What to Expect After Aquablation Surgery

Most men who undergo Aquablation for an enlarged prostate experience a recovery that involves a catheter for one to three days, blood-tinged urine that gradually clears over several weeks, and noticeable improvement in urinary symptoms within the first month. The procedure uses a high-pressure waterjet guided by ultrasound imaging to remove excess prostate tissue without generating heat, which shapes the recovery profile in ways that differ from older surgical techniques. What happens during the weeks and months after surgery depends partly on prostate size, partly on individual healing, and partly on how experienced the surgical center is with the technology.

The First Few Days and Leaving the Hospital

After the procedure, you’ll wake up with a urinary catheter in place. The catheter typically stays in for one to three days while the surgical site stabilizes. During that time, you can expect the urine draining through it to appear red or pink. Most men experience only mild pain during this phase. A study of 60 consecutive patients found that pain scores were minimal in the early postoperative period, and the vast majority of men in that series were discharged on the same day as surgery.

Same-day discharge is becoming more common as centers gain experience. In that same series, where the average prostate size was a substantial 115 mL, 98% of men went home the day of surgery with no transfusions and no returns to the operating room required.¹ That said, many hospitals still keep patients overnight, especially early in their experience with Aquablation or when the prostate is very large. You should plan for at least one night in the hospital and be pleasantly surprised if your surgeon clears you for same-day discharge.

Blood in the Urine and the Bleeding Question

Bleeding is the most discussed aspect of Aquablation recovery, and for good reason. Because the waterjet removes tissue without generating heat, it does not cauterize blood vessels the way a traditional electrosurgical tool does. After the tissue is resected, the surgeon uses a separate cauterization step to control bleeding, but some oozing is expected during healing. Visible blood in your urine, called hematuria, is normal for several weeks. It tends to be heaviest in the first few days, then lightens gradually, sometimes flaring briefly around the two-to-three-week mark as scabs inside the prostate slough off.

The rate of blood transfusion after Aquablation has been a moving target as surgical technique has evolved. Early data showed roughly 6 to 8 percent of patients needed a transfusion. With refinements in how surgeons cauterize the surgical bed, particularly a 360-degree cauterization technique near the bladder neck, one center reported dropping its transfusion rate to under 1%.² A safety review across multiple studies confirmed that most complications after Aquablation are minor, with transfusion needed in roughly 1 to 8 percent of cases depending on the center and the size of the prostate.³

Some surgeons have explored giving tranexamic acid, a medication that helps blood clot, during surgery to reduce blood loss. One preliminary study found that men who received it had a smaller drop in hemoglobin levels afterward compared to those who did not.⁴ However, a larger study of 131 patients found that among those who received thorough cauterization during the procedure, tranexamic acid did not make a meaningful additional difference in blood-related outcomes, and emergency visits for hematuria were minimal regardless.⁵ The takeaway is that careful surgical technique during the procedure itself matters more than any single medication for keeping bleeding in check.

When Urinary Symptoms Actually Improve

You’ll likely notice some improvement in your urinary stream within the first few weeks, but it takes time for the full benefit to emerge. In the first month, your body is still healing, and temporary irritative symptoms like urgency, frequency, and a burning sensation during urination are common. These storage symptoms are a normal part of the prostate healing and usually settle down within six to twelve weeks.

The long-term improvement, though, is where the data gets encouraging. In a randomized trial comparing Aquablation to the standard older procedure (TURP), men who had Aquablation saw their symptom scores improve by about 15 points on a standard 35-point scale at five years, with their peak urinary flow rate more than doubling compared to baseline.⁶ That improvement was statistically comparable to what TURP achieved. For men with larger prostates specifically, the five-year results from a dedicated trial showed symptom scores dropping from about 23 to 7 on average, with peak flow rates roughly doubling from around 9 to 17 mL per second.⁷

Real-world data outside of clinical trials tells a similar story. The largest single-center study with four-year follow-up reported symptom scores improving from about 24 at baseline to 7, with peak flow rising from roughly 6 to 17 mL per second.⁸ In practical terms, men who were getting up multiple times a night, straining to urinate, and dealing with a weak dribbling stream typically found those problems substantially resolved and staying resolved years later.

What Happens to Sexual Function

Preservation of sexual function is one of the main reasons men and their urologists consider Aquablation over traditional alternatives. The procedure’s ability to precisely target tissue using robotic guidance, while avoiding heat damage to surrounding structures, appears to protect the mechanisms responsible for both erections and ejaculation better than many competing techniques.

A systematic review pooling data from multiple studies found that between 72 and 99.6 percent of men maintained antegrade ejaculation after Aquablation, meaning they could still ejaculate normally during orgasm rather than experiencing retrograde ejaculation, where semen travels backward into the bladder. Erectile function remained stable across all of the reviewed studies. When Aquablation was directly compared to TURP in a randomized trial, the Aquablation group had significantly lower rates of ejaculatory dysfunction, and that advantage persisted for up to five years.⁹ An Italian real-world study of 300 consecutive patients reported 88% preservation of antegrade ejaculation.¹⁰

For men who place a high priority on maintaining normal ejaculation, those numbers represent a meaningful improvement over TURP, which commonly causes retrograde ejaculation in 50 to 75 percent of patients. Keep in mind that preservation rates depend partly on prostate anatomy and the extent of tissue removed, so individual results can vary. Still, this remains one of Aquablation’s strongest selling points relative to traditional surgery.

Urinary Continence After the Procedure

Incontinence, or losing control of urine, is one of the fears men bring to any prostate surgery. The evidence on Aquablation is reassuring on this front. Multiple studies have reported no cases of new-onset urinary incontinence after the procedure. In the Italian multicenter cohort, continence was preserved in all patients through three years of follow-up.¹¹ The 300-patient study also reported zero cases of new incontinence, defining continence as no pad use and no patient-reported stress or urge incontinence at follow-up.¹⁰

That does not mean you won’t experience any urinary control issues in the first few weeks. Temporary urgency, a sense that you need to get to the bathroom quickly, and occasional dribbling are common in the early healing period. These storage symptoms are distinct from true incontinence and typically resolve as inflammation subsides. One study tracking continence questionnaire scores in men with both smaller and larger prostates found that scores improved by roughly 40 percent from baseline over two years, suggesting that men actually gained better urinary control than they had before surgery.¹²

How Prostate Size Shapes Your Recovery

One of the things that distinguishes Aquablation from several competing procedures is that it can treat very large prostates, sometimes over 150 mL, where traditional TURP becomes impractical. But prostate size does influence the recovery experience. A study specifically examining this found that men with prostates under 100 mL had shorter operating times, required less irrigation fluid during surgery, and experienced a smaller drop in hemoglobin afterward compared to men with prostates at or above that threshold.¹³ That means if your prostate is on the larger side, you should expect a somewhat longer procedure and a slightly higher chance of needing to manage heavier bleeding.

That said, the procedure’s outcomes remain strong even in large prostates. A case report of a man with a large prostate and an intravesical median lobe, a configuration that can be particularly tricky to treat, documented substantial improvement in both symptom score and urinary flow at three months.¹⁴ The five-year trial data for prostates between 80 and 150 mL showed durable symptom relief comparable to what smaller-prostate men experience.⁷ The recovery may be a bit rougher at the start, but the endpoint is similar.

Potential Complications and Readmission Risk

Beyond bleeding, the most common complications after Aquablation are urinary retention (temporary inability to urinate after the catheter is removed, sometimes requiring a new catheter), urinary tract infection, and irritative voiding symptoms. Severe complications graded 3 or higher on the standard surgical complication scale are uncommon and usually related to bleeding or retention.³ Long-term problems like urethral stricture or bladder neck contracture, which can occur after older resection techniques, are rare after Aquablation.

One area where the data is less flattering involves readmissions. A comparative analysis found that patients who underwent Aquablation were more likely to be readmitted within 30 or 90 days and more likely to need a catheter reinserted compared to men who had other surgical treatments for BPH. The same study noted that when it excluded patients treated during 2023, the early-adoption period for many centers, the elevated readmission rate disappeared. The authors attributed this pattern to the learning curve associated with adopting a new technology and to Aquablation being applied to larger prostates that may carry inherently higher complication risk.¹⁵ If you’re considering Aquablation, asking your surgeon about their case volume and experience with the technology is worth doing. Outcomes appear to improve as centers move past their initial learning phase.

How Aquablation Compares to Other Procedures

If you’re weighing Aquablation against TURP, the randomized trial data suggests that both procedures deliver similar improvements in urinary symptoms and quality of life out to five years. Quality-of-life improvements were essentially identical at two years between the two procedures.¹⁶ Where Aquablation pulls ahead is in ejaculatory preservation. Where TURP may have an edge is in lower bleeding risk and a longer track record.

The comparison with HoLEP, a laser-based enucleation technique often considered the gold standard for larger prostates, is more nuanced. A prospective study found that Aquablation had an early advantage in ejaculatory and continence function at three months, but by the six-month mark and beyond, the two procedures performed similarly on most measures. HoLEP had a shorter operating time and removed more tissue, while Aquablation had a higher rate of severe complications in that study.¹⁷ A network meta-analysis comparing the two across multiple studies found that both produced similar symptom improvements, but HoLEP achieved better post-void residual volume reduction and tended toward lower blood loss, while Aquablation had shorter hospital stays and potentially lower incontinence risk.¹⁸

The honest summary is that no single procedure “wins” across every dimension. Aquablation’s strengths are its ability to handle large prostates effectively, its ejaculatory preservation rates, its relatively short hospital stay, and its robotic precision that reduces variability between surgeons. Its weaknesses relative to some alternatives are higher bleeding rates and the ongoing learning curve at newer centers.

Quality of Life and the Longer View

Beyond the specific measurements of flow rate and symptom scores, pooled data from five international studies examining quality of life after Aquablation found sustained improvement in patient-reported quality of life alongside preserved sexual function at the five-year mark.¹⁹ That analysis was particularly notable because it focused on men who started with poor quality of life, exactly the group most in need of meaningful relief. The results showed these men achieved significant and lasting gains.

What this means practically is that the worst of the recovery, the catheter, the bloody urine, the temporary urgency, is concentrated in the first few weeks. By three months, most men are experiencing substantially better urinary function than they had before surgery. By six months to a year, the full benefit is typically established, and the data suggests it holds steady for at least five years in most patients.

The Cost Question

One factor that does not show up in clinical outcome data but matters in the real world is cost. An in-hospital cost analysis comparing Aquablation to TURP found that Aquablation was significantly more expensive, averaging roughly 3,500 euros more per patient. The difference was driven primarily by the cost of the disposable surgical supplies and the robotic system itself, not by longer hospital stays or more follow-up care.²⁰ Insurance coverage for Aquablation varies by country and by plan. In the United States, many major insurers now cover the procedure, but you should verify coverage before scheduling. The growing trend toward outpatient same-day discharge may help narrow the overall cost gap by eliminating overnight hospital charges, though the device costs remain a factor.
