Aquablation Therapy is the robotic, heat-free, ultrasound-guided treatment for an enlarged prostate. Unlike TURP or laser, it opens your urinary flow while protecting your erections, ejaculation, and continence. Performed by Dr. Ali Tourchi at LPG Urology.
Lower urinary tract symptoms (LUTS) caused by BPH are very common with age. The five symptom patterns below are the most frequent presentations seen in clinical practice.
Millions of men over 50 wake up 2–4 times at night, strain to urinate, or rush to the bathroom feeling desperate. These are the most common complaints of Benign Prostatic Hyperplasia (BPH). You are not alone — and every symptom is fixable with modern treatment.
You could hold it through a long drive. The stream was strong. You slept through the night. You emptied completely and never thought about any of it — because your body was working exactly as designed.
As men age, the prostate gradually enlarges. This is called benign prostatic hyperplasia (BPH). It is not cancer, but it can obstruct urinary flow in three distinct anatomic patterns. The pattern of enlargement guides which treatment is most appropriate.
The lateral lobes (the side portions of the prostate) grow inward and compress the urethra from both sides. The bladder must work harder to overcome the resistance, producing a weak stream, hesitancy, and incomplete emptying.
The median lobe grows down into the bladder neck and behaves like a one-way ball valve. When the bladder contracts, the lobe is pushed downward and seals the bladder outlet. Patients feel urgency but have difficulty initiating the stream.
Both the lateral lobes and the median lobe enlarge simultaneously. The lateral lobes compress the urethra from the sides while the median lobe obstructs the bladder outlet from above. This pattern carries the highest risk of acute urinary retention.
The prostate is only part of the picture. Over years of working against an obstructed outlet, the bladder muscle hypertrophies — it grows thicker. Eventually the muscle can decompensate (lose contractile function). Once that occurs, even technically successful prostate surgery may not fully restore normal voiding. This is why earlier evaluation matters.
Discuss these symptoms with your physician promptly: post-void dribbling · sensation of incomplete emptying · urinary frequency within 5 minutes of voiding · recurrent UTIs · gross hematuria · rising serum creatinine · nocturia of 4 or more times per night · persistent straining throughout the stream. A simple bladder scan measures post-void residual urine. A residual greater than 100 mL suggests significant obstruction and warrants urologic assessment.
For decades, the two standard surgical options for an enlarged prostate have been transurethral resection of the prostate (TURP) — using electrical current to remove tissue — and laser vaporization or enucleation. Both procedures relieve obstruction effectively, but both rely on heat energy that can affect the nerves and structures responsible for sexual function. Newer technologies, including Aquablation, are designed to reduce these heat-related side effects while still relieving the blockage.
Aquablation Therapy combines real-time ultrasound radar, AI-guided planning, robotic execution, and the judgment of your surgeon. Together, they deliver an outcome that is not possible with TURP or laser surgery.
Dr. Tourchi places a small ultrasound probe that creates a live, 3D picture of your prostate — updating 30 times per second. Every structure is visible: the outer capsule wall, the lateral lobes, the median lobe, the verumontanum (your sex-function landmark), the sphincter, and the nerve bundles outside the capsule. Nothing is hidden. Nothing is guessed.
On the ultrasound image, Dr. Tourchi marks the exact tissue to remove (red) and the exact structures to spare (green). This treatment boundary is locked 3–5 mm above the verumontanum — preserving your ejaculation — and stops short of the capsule — preserving the nerves that control your erections.
A high-pressure stream of cold saline (~20°C, room temperature) sweeps across your prostate, removing the tissue squeezing your urinary flow. No heat. No burning. No electrical current. The robot executes Dr. Tourchi's plan with submillimeter precision. Average active treatment time: just 5.8 minutes.
Aquablation is most often performed as an outpatient procedure, with most patients discharged the same day; some patients may be observed overnight based on individual factors. There are no external incisions — the procedure is performed through the natural urinary channel. A urinary catheter is typically required for 3–4 days after surgery. Most patients return to light activity within about a week, with continued improvement in urinary flow over 4–6 weeks. Published 5-year data show favorable preservation of erectile and ejaculatory function.
Aquablation Therapy is not just another surgery with a new name. It's a next-generation surgical platform — integrating real-time ultrasound imaging, artificial intelligence treatment planning, robotic execution, and a heat-free waterjet. Nothing else in urology works this way.
For most men, the biggest fear isn't the procedure itself — it's the hospital stay, the cutting, the long recovery. Aquablation takes all three off the table.
Most men with BPH start with lifestyle changes and medication. Surgery becomes the right next step when one or more of the following conditions applies — these are the established indications, in line with American Urological Association (AUA) guidelines.
An adequate trial of medications — alpha-blockers (Flomax, Rapaflo), 5-ARIs (Proscar, Avodart), tadalafil 5 mg daily, or combination therapy — has not provided sufficient symptom relief. AUA/IPSS score remains moderate (8–19) or severe (≥20).
Single or recurrent episodes of acute urinary retention requiring catheter drainage. A trial without catheter on alpha-blocker therapy was unsuccessful, or the patient remains catheter-dependent.
Rising creatinine, declining eGFR, or imaging that shows hydronephrosis or hydroureteronephrosis caused by bladder outlet obstruction. Surgical decompression is medically necessary to protect kidney function.
Multiple UTIs caused by incomplete bladder emptying and elevated post-void residual. Antibiotics alone are not enough — the underlying obstruction must be relieved.
Bladder calculi seen on imaging or cystoscopy, caused by urinary stasis from BPH. Recurrent stone formation is a direct complication of obstruction and warrants definitive treatment.
Visible blood in the urine from prostatic bleeding, after other sources have been excluded. If 5-ARI therapy has been trialed without success, surgical management of the prostate is the next step.
Intolerance of long-term medical therapy (side effects, dizziness, sexual side effects), inability to reliably take daily medications, or preference for a one-time definitive solution over lifelong pills. Alpha-blocker therapy may also be contraindicated due to planned cataract surgery (IFIS risk).
If one or more of these applies, surgical evaluation is appropriate. Your urologist will review your case in detail, confirm the indication, discuss the surgical and non-surgical alternatives, and answer every question you have before any treatment is recommended.

Stop the following 7 days before your procedure, unless another physician specifically tells you not to stop:
Do NOT stop any blood thinner on your own. These medications must only be stopped after approval from the physician who prescribes them — your cardiologist, primary care, vascular doctor, neurologist, or hematologist. If you have a heart stent, mechanical valve, recent stroke/TIA, atrial fibrillation, recent clot, pulmonary embolism, or vascular graft, a written plan from your prescriber is required before surgery.

Tell our office if you take any of these:
Do not restart any blood thinner until specifically instructed by your surgeon or prescribing physician. Restart timing depends on urine color, catheter status, your cardiac/clotting risk, and bleeding during surgery. Most patients restart between 24–72 hours post-op, but the plan is always individualized.
Stopping blood thinners can increase the risk of stroke, heart attack, stent thrombosis, valve thrombosis, DVT, or pulmonary embolism. Continuing them can increase the risk of bleeding, clot retention, catheter problems, transfusion, or return to the operating room. For this reason, every patient's plan is individualized and coordinated between your surgeon, anesthesia, and your prescribing physician.
Aquablation removes obstructing prostate tissue through the urinary channel. Because the prostate and bladder neck are healing internally, urinary symptoms for several weeks are normal. Here is what to expect — and what to call about.
Some blood in the urine can come and go for 3–4 weeks after the procedure — this is normal.
Some blood in the urine is expected and may come and go for several weeks. Use this guide to know which colors are normal during healing and which colors should prompt a call to the office or a visit to the ER. If bleeding increases, stop activity, rest, and hydrate.
Unless you are on fluid restriction (heart failure, kidney disease): drink 2–3 liters of water per day for the first 1–2 weeks. Drink enough that urine stays light pink or clear. Reduce fluids 2–3 hours before bedtime if nighttime urination is severe.
Conventional surgical options for BPH — TURP (electrical) and laser — rely on thermal energy to remove tissue, which can affect the nerves responsible for erections and the bladder neck mechanism that prevents retrograde ejaculation. Aquablation uses a high-velocity waterjet under live ultrasound guidance to remove tissue mechanically, without heat.
Three major clinical trials — WATER, WATER II, and OPEN WATER — have followed patients for five years after Aquablation Therapy. The outcomes hold up in both controlled trials and real-world community practice.
