During Aquablation, patients experience no pain because the procedure is performed under general or spinal anesthesia. After the procedure, pain is typically mild to moderate, including temporary burning during urination, pelvic pressure, and urgency that usually resolves within a few days to weeks. Most discomfort can be managed with over-the-counter pain relievers like ibuprofen or paracetamol.
Aquablation uses a heat-free, robotically-guided water jet to precisely remove excess prostate tissue, causing less trauma than traditional surgical methods like TURP. Post-procedure symptoms commonly include blood in urine for several weeks, temporary difficulty urinating due to swelling, and urinary urgency as the bladder adjusts. Recovery is generally smoother and faster compared to conventional prostate surgeries, with most patients resuming normal activities within days and experiencing preserved sexual function in the majority of cases.

What Is Aquablation, and How Does It Work?
Aquablation is a specialised treatment for benign prostatic hyperplasia (BPH). This minimally invasive procedure, approved by the Food and Drug Administration, combines advanced imaging and robotic precision to target excess prostate tissue. Using a robotically guided camera and ultrasound, the prostate is mapped in detail to create a personalised treatment plan. A high-pressure water jet, free of heat, is then directed to remove the overgrown tissue effectively. This approach helps minimise damage to surrounding areas while providing a precise and tailored solution for BPH.

How painful is Aquablation?
Aquablation therapy is a minimally invasive procedure used to treat an enlarged prostate (BPH). While any medical procedure involves some level of discomfort, Aquablation is designed to minimise pain. Since it is performed under general or spinal anaesthesia, patients do not feel pain during the procedure itself.
After the procedure, mild to moderate discomfort, including a burning sensation during urination or pelvic pressure, is common for a few days. Some patients may also experience temporary urgency or blood in the urine, but these typically subside within a couple of weeks. Compared to traditional surgical methods, Aquablation generally results in less post-procedure pain and a quicker recovery. Always consult a healthcare professional for personalised guidance on pain management and recovery.
Who Can Benefit from Aquablation?
Aquablation is a suitable treatment for individuals experiencing symptoms of benign prostatic hyperplasia (BPH). It can be performed on prostates of any size and may help those dealing with:
- Frequent or urgent need to urinate
- A weaker or slower urinary stream
- Waking up multiple times at night to urinate
- A lingering sensation of incomplete bladder emptying
How Aquablation Works
This procedure is completed in two steps under general anaesthesia.
First, a robotic imaging system creates a customised surgical map based on the patient’s anatomy. A small camera, inserted using a cytoscope, works alongside ultrasound imaging to provide a clear view of the prostate. This dual imaging technique allows the surgeon to identify and remove only the necessary prostate tissue while preserving key structures to reduce risks such as ejaculation issues.
In the second step, a heat-free, high-pressure water jet, controlled by robotic precision, follows the surgical plan to remove the targeted prostate tissue. The software ensures that the surgeon can design and execute the procedure with optimal accuracy, enhancing safety and outcomes.
Recovery After Aquablation
Following the procedure, patients wake up in the recovery room with a catheter that helps drain urine and rinse the bladder to clear any bleeding. Most individuals remain under medical supervision for two to three hours as they recover from anaesthesia.
The catheter remains in place until the doctor confirms that the urine is sufficiently clear. Some patients may need to stay overnight in the hospital, while others can go home the same day once they are stable. Medication may be prescribed to ease any burning sensation.
For those discharged with a catheter, detailed instructions will be provided on how to maintain it, including flushing to prevent blockages and proper emptying techniques.
Advantages of Aquablation
Aquablation is a minimally invasive, robot-assisted procedure that utilises a high-powered water jet without heat. It does not require incisions, and recovery time is comparable to traditional surgical options.
Although Aquablation is a relatively new treatment, early research is promising. A study published in October 2023 involving 113 patients found that 98% of participants regained the ability to urinate successfully, highlighting its effectiveness in managing urinary retention. This innovative approach continues to show potential as a precise and safe treatment for BPH symptoms.
Comparing Aquablation and TURP: A Safer Alternative?
Aquablation is emerging as a potential alternative to transurethral resection of the prostate (TURP), offering both effectiveness and safety. Clinical trials comparing the two procedures found that urine flow improvement and symptom relief for benign prostatic hyperplasia (BPH) were similar. However, Aquablation showed a lower risk of side effects, particularly in preserving ejaculatory function. This makes it a compelling option for those seeking effective treatment with fewer complications.

What to Expect After Aquablation: Common Side Effects and Recovery Tips
Following post-procedure care instructions is crucial for a smooth recovery. If side effects feel unusual or concerning, patients should contact their healthcare provider. Below are some common side effects of Aquablation and tips for managing them effectively.
Blood in Urine: It’s normal to notice blood in the urine for several weeks after the procedure. The blood may be most visible at the start of urination and could clear as the stream continues. Staying well-hydrated is essential—drinking plenty of fluids helps flush the urinary tract and promote healing.
Difficulty Urinating: Swelling around the urethra may cause temporary difficulty with urination. As the swelling reduces, urination should gradually become easier week by week. If urination becomes painful or overly difficult, patients should seek medical advice.
Urinary Urgency: Sudden, intense urges to urinate may occur while the bladder adjusts to the removal of excess prostate tissue. This is temporary, and the muscles controlling the urinary sphincter will strengthen over time. Practicing bladder control techniques and following medical guidance can help manage urgency.
Changes in Sexual Response: Once the urine clears and at least two weeks have passed, it is generally safe to resume sexual activity. Most people do not experience changes in orgasm or ejaculation, but some may notice reduced semen volume or a temporary absence of ejaculation. These effects vary and may improve with time.
By following recovery guidelines and maintaining open communication with their healthcare provider, patients can support their healing process and return to normal activities with confidence.

How Aquablation Improves Quality of Life for BPH Patients
Benign prostatic hyperplasia (BPH) can severely impact a man’s quality of life, leading to frequent urination, weak urinary flow, and interrupted sleep due to nighttime trips to the bathroom. Aquablation effectively addresses these issues by restoring normal urinary function without compromising sexual health. Unlike traditional surgical procedures, which may cause ejaculatory dysfunction, Aquablation is designed to preserve key structures, reducing this risk. Patients report significant improvements in their ability to empty the bladder completely, fewer disruptions during the night, and enhanced comfort during the day. The procedure’s minimally invasive nature also ensures a faster recovery, allowing men to return to work and daily activities with minimal downtime. Aquablation provides lasting relief, offering renewed confidence and a better quality of life.
Conclusion
Aquablation is revolutionising the treatment of benign prostatic hyperplasia (BPH) by offering a minimally invasive, highly precise alternative to traditional surgical methods. By using a heat-free, high-pressure water jet guided by robotic imaging, this procedure minimizes damage to surrounding structures, reducing the risk of complications such as incontinence and sexual dysfunction. Patients experience less post-procedure pain, a faster recovery, and long-term symptom relief. Compared to traditional surgeries like TURP, Aquablation preserves ejaculatory function and enhances overall quality of life. As more clinical studies support its effectiveness and safety, Aquablation is emerging as a leading choice for men seeking a reliable, low-risk treatment for BPH. By understanding its benefits, patients can make informed decisions and regain control over their urinary health with confidence.

I underwent Aquablation therapy on Tuesday morning. After the procedure, I had a catheter in place while my medical team flushed my bladder until Wednesday morning. When they removed the catheter, it wasn’t uncomfortable, but I couldn’t urinate on my own, so they sent me home with a catheter. Fortunately, I’ve experienced very little pain after the procedure. The only mild discomfort I’ve had is a slightly sore throat from the breathing tube used during surgery. I’ll return to the clinic on Monday to have the catheter removed. In the meantime, I’m drinking three litres of water daily to stay hydrated. The only upside of having a catheter is that I don’t have to wake up at night to pee. Looking forward to great results!

I had my procedure on Tuesday. After reading multiple forums about post-procedure experiences, I was more anxious about recovery than the surgery itself. Now, three days later, I’m doing well—taking it easy, experiencing good urine flow, and noticing some blood in my urine, but not much discomfort. I feel better than I expected, which is a relief. So far, everything looks positive. Now, I’ll see how the next few weeks unfold.
