💬In plain words
What the trial is, and whether it could suit you
This clinical trial tests whether the magnetic resonance imaging (MRI)-guided transurethral ultrasound ablation (TULSA) procedure is safe and effective in treating patients with low to intermediate grade prostate cancer. MRI-guided TULSA ablation is a minimally invasive procedure that uses an ultrasound device guided by MRI imaging to deliver high-energy sound waves, producing very high temperature to ablate (destroy) tumor cells in a targeted manner. The MRI-guided TULSA procedure may help patients avoid surgery and help improve prostate cancer patients' quality of life.

* Stage =\< T2c, N0, M0
* International Society of Urological Pathology (ISUP) grade group 1, 2, or 3 disease on transrectal ultrasonography (TRUS)-guided biopsy (minimum 8 cores, combination of systematic and MRI fusion-guided) or in-bore biopsy \[minimum 3 cores from each Prostate Imaging-Reporting and Data System (PI-RADS) version (v)2 category \>= 3 lesion\]. Biopsy reported within 12 months of baseline visit, with minimum 6-week interval between biopsy and baseline
* Prostate specific antigen (PSA) =\< 20 ng/mL reported within 3 months of baseline
* Treatment naive
* Planned ablation volume \< 3.0 cm axial radius from the urethra on mpMRI acquired within 6 months of baseline
Exclusion Criteria:
