You've heard the word *cancer,* and the ground shifted beneath you. Now you're reading everything you can, trying to separate real answers from noise.
MRI-guided prostate ablation is one of those answers worth understanding clearly.
MRI-guided prostate ablation is a minimally invasive treatment that uses real-time magnetic resonance imaging to direct thermal energy at cancerous prostate tissue. The MRI lets your physician see exactly where the tumor sits, where your nerves run, and where your urinary sphincter lives.
Because the imaging happens in real time, your physician adjusts the energy delivery as the treatment progresses. Healthy tissue stays intact. The cancer gets targeted with sub-millimeter precision.
Conventional approaches force a trade-off.
Radical prostatectomy removes the entire prostate through incisions, putting the nerves that control erections and continence at direct risk.
Radiation therapy sends energy through healthy tissue over 5 to 40 sessions, with damage that may not show until years later.
MRI-guided ablation takes a different path.
There are no incisions and no radiation exposure. The treatment is delivered through the urethra, from the inside out, heating only the tissue your physician has mapped for destruction.
This inside-out approach means the neurovascular bundles that protect sexual function and bladder control aren't in the direct line of fire. A 2025 review in Prostate Cancer and Prostatic Diseases showed MRI-guided transurethral ultrasound ablation preserves functional outcomes at high rates compared to traditional whole-gland treatments. The CAPTAIN head-to-head randomized clinical trial of TULSA-PRO vs. radical prostatectomy has already started reporting favorable TULSA functional outcomes.
Not every man with prostate cancer qualifies. As with surgery or radiation, TULSA candidates are men diagnosed with localized, organ-confined disease, meaning the cancer hasn't spread beyond the prostate. Low-risk and intermediate-risk profiles (Gleason grade groups 1 through 3) tend to see the strongest outcomes.
An MRI-visible tumor allows for precision targeting. Men with certain implants such as orthopedic hardware or Urolift™ prostatic implants, large prostatic calcifications, or urethral strictures need additional evaluation.
At Integrative Urology, Dr. Y. Mark Hong personally reviews every MRI, imaging and pathology information before confirming candidacy. If the fit isn't right, he'll tell you directly.
You are comfortable under sedation for the entire treatment. A small ultrasound applicator is inserted through the urethra alongside a cooling device that protects the rectum.
Once you're positioned inside the MRI, your physician can see the prostate, the tumor boundaries, and every critical structure around them. Treatment boundaries are customized based on your anatomy, and then directional ultrasound energy is delivered within those boundaries.
The MRI monitors tissue temperature in real time, so adjustments also happen real-time by the surgeon. The whole process takes one to three hours, and you go home the same day.
Your nerves don't lie in a textbook diagram. They wrap around the prostate in patterns unique to your body. Real-time MRI lets your physician see those exact nerve positions during treatment, not days before on a static scan.
Because the ablation works from the inside out (starting at the urethra and heating outward), energy can be controlled before reaching the neurovascular bundles on the prostate's outer edge. Data from the TACT pivotal trial's four-year follow-up showed 87% of previously potent men maintained erections sufficient for penetration — up from 75% at one year — and 94% remained pad-free continent.
At Integrative Urology, functional preservation isn't a secondary benefit. It's the standard we hold ourselves to, because your identity is not negotiable.
Forget weeks in bed or months of physical therapy. After MRI-guided ablation, most men resume light activities within days. A temporary catheter stays in place for a short period, and patients consistently describe it as manageable.
The outpatient, same-day format means no hospital admission. You sleep in your own bed. You eat your own food. You get back to the life you built.
Integrative Urology's continuity-of-care commitment means Dr. Hong doesn't disappear after your treatment day. You receive direct MRI review and follow-up, a personalized restoration plan, and ongoing physician-led oversight.
The clinical evidence is building, and the numbers are direct. In the TACT pivotal trial, 96% of 115 men experienced PSA reductions of 75% or greater at 12 months.
Among the intermediate-risk men in the trial, 79% were free of Grade Group 2 or higher disease at one-year biopsy
Four-year follow-up showed sustained cancer control, and only 16% of men in the trial required salvage therapy — with the treatment leaving future paths like surgery or radiation still open if needed.
These observations and claims are published in the Journal of Urology and jave been presented at the American Urological Association's annual meetings.
Focal therapy treats only the visible tumor, leaving the rest of the prostate intact. Whole-gland ablation treats the entire prostate while still sparing the urethra and sphincter. The distinction matters because prostate cancer is often multifocal, meaning it shows up in more than one spot.
Whole-gland TULSA-PRO treatment addresses both visible and potentially hidden disease in a single session. For men who want definitive cancer control without the trade-offs of radical surgery, this approach fills a critical gap.
Dr. Hong has performed over 250 whole-gland TULSA Procedures personally and independently — an ever-increasing milestone Profound Medical has recognized as a world-first: 200 procedures performed by a single urological surgeon without radiologist involvement.
That volume of experience translates into precision you can measure.
MRI-guided prostate ablation treats localized cancer with precision that traditional approaches can't match. It preserves what matters: your sexual function, your bladder control, your dignity.
You are a man with a life you spent decades building. Integrative Urology exists to protect that life while eliminating the cancer threatening it. You deserve a path that honors both.
[We invite you to a private consultation with Dr. Hong to find out if TULSA-PRO is right for you and your case.]
TULSA-PRO received FDA 510(k) clearance in August 2019, based on results from the TACT pivotal clinical trial. Clearance is the standard regulatory pathway most medical devices go through — distinct from the "approval" pathway used for new drugs — and means the FDA reviewed the device and its supporting clinical data before authorizing it for market use.
Dr. Y. Mark Hong at Integrative Urology uses this technology to deliver precise, whole-gland prostate cancer treatment guided by real-time MRI imaging.
The treatment itself takes one to three hours. You go home the same day.
At Integrative Urology, Dr. Hong personally performs every imaging review, consultation, and the procedure itself, ensuring precision from start to finish.
You are comfortable under sedation during the entire treatment.
Integrative Urology's TULSA-PRO approach is incision-free and performed through the urethra, reducing post-treatment discomfort significantly.
Yes. Unlike radiation, MRI-guided ablation does not limit your future treatment paths. If cancer recurs, you can undergo another ablation session or pursue surgery or radiation therapy.
Many men resume daily routines within days.
Integrative Urology's same-day outpatient TULSA-PRO treatment allows you to go home hours after the session, with a personalized restoration plan guiding your return to full activity.
