If you've been researching treatment options for prostate cancer, two names keep coming up: TULSA-PRO and HIFU. Both use focused thermal energy to destroy cancerous prostate tissue. But how each device is guided, how energy reaches the gland, and how each protects the structures responsible for erections and continence are meaningfully different.
This comparison walks through those differences — guidance, energy delivery, treatment scope, and clinical evidence — so you can talk through the right questions with your care team.
Integrative Urology is a Phoenix-based practice led by Dr. Y. Mark Hong, who trained at Stanford and Harvard and has personally performed more than 200 whole-gland TULSA-PRO procedures (sourced: Profound Medical, Nov 2025).
Considerations:
HIFU (High-Intensity Focused Ultrasound) delivers focused sound waves from a rectal probe through the rectal wall to the prostate. Multiple overlapping sonications cover the treatment zone.
Traditional HIFU is typically monitored with ultrasound; MRI-guided HIFU systems also exist but are less widely deployed.
Benefits:
Considerations:
TULSA-PRO operates inside an MRI suite, giving the treating physician a live, high-resolution view of the prostate, the tumor, and surrounding structures throughout treatment, with closed-loop temperature feedback confirming energy stays within the planned boundary.
Traditional HIFU is monitored by ultrasound, which offers less soft-tissue contrast than MRI. MRI-guided HIFU systems close some of this gap but are not yet as widely available as TULSA-PRO.
TULSA-PRO's transurethral device rotates inside the urethra, directing ultrasound energy outward toward the prostate boundary — an inside-out path that keeps energy away from the rectum, with active cooling of both the urethra and rectal wall.
HIFU's rectal probe fires focused sound waves inward through the rectal wall in overlapping sonications — an outside-in path that necessarily passes through non-target tissue before reaching the prostate.
TULSA-PRO can be configured for focal, hemi-gland, or whole-gland ablation. HIFU is most established for focal treatment of smaller lesions (typically up to ~40cc, with some centers extending this with adjunctive treatment). Whole-gland HIFU exists but is used more selectively due to the added risk profile of outside-in delivery at larger volumes.
Protecting sexual function and continence is central to how TULSA-PRO is positioned. The CAPTAIN trial (211 men, 23 sites) showed better quality-of-life scores for TULSA-PRO than robotic prostatectomy in the first 30 days.
TULSA-PRO is supported by the CAPTAIN randomized controlled trial and the TACT pivotal FDA registration trial.
HIFU has prospective registry and single-arm study data with multi-year follow-up confirming oncologic control in well-selected focal cases. A head-to-head randomized trial between HIFU and a comparator has not been completed at the scale of CAPTAIN.
Different approaches. Different considerations.
There isn't one treatment path for every prostate cancer diagnosis. Start by understanding your options—then decide what fits yours.
There isn't a single right answer for every diagnosis. The better fit depends on tumor location, prostate volume, and your priorities for recovery and preservation of function — which is exactly what a candidacy consultation is for.

You didn't spend decades building your life, your relationships, your career, your sense of who you are, to hand it all over to a treatment that guesses where the boundaries should be. Integrative Urology gives you MRI-guided precision that sees, measures, and confirms every boundary in real time.
Dr. Hong has performed more TULSA-PRO treatments than any urologist on the planet. He does it himself. Personally. The CAPTAIN trial isn't a talking point. It's Level 1, randomized evidence that proved TULSA-PRO preserves erections and continence at more than twice the rate of robotic prostatectomy.

TULSA-PRO treats the prostate from inside the urethra outward under live MRI guidance, while HIFU sends focused ultrasound from a rectal probe inward through the rectal wall using ultrasound imaging. Integrative Urology's TULSA-PRO also actively cools both the urethra and rectum to protect surrounding structures.
No. HIFU is a focal-only approach designed for smaller, well-defined lesions up to approximately 40 cc. If your cancer is multi-focal or you need whole-gland treatment, Integrative Urology's TULSA-PRO offers that flexibility in a single session.
The CAPTAIN trial, presented at EAU 2026, showed that men treated with TULSA-PRO were more than twice as likely to preserve both erections and pad-free continence at six months compared to robotic prostatectomy. Integrative Urology uses this same technology under Dr. Hong's direct care.
TULSA-PRO's inside-out delivery and active nerve-bundle cooling give it a structural advantage for protecting the nerves responsible for erections. Integrative Urology's clinical data shows 87% of men preserve erections at five years after whole-gland treatment.
Integrative Urology performs TULSA-PRO as a same-day outpatient treatment. Men typically resume light activities in days. The CAPTAIN trial confirmed that TULSA-PRO patients returned to work in a median of 10 days, compared to 19 days after robotic surgery.
Integrative Urology is located in Phoenix, Arizona, and men travel nationally and internationally for Dr. Hong's expertise. The practice offers concierge-level support to coordinate consultations, pre-treatment planning, and follow-up care for out-of-town visitors.
