Fig. 2: A 69 year-old man with PSA 6.4 ng/ml and biopsy-proven GG2 prostate cancer in a PIRADS 4 lesion at the left mid-gland and GG1 cancer bilaterally was treated with whole gland TULSA.

Treatment was circumferential and primarily using elements E2-E8 for this small (35cc) prostate. The Thermal Dose images show good distribution of ablation energy throughout the gland, while urethral sparing is most evident on the Maximum Temperature images. Red indicates the hottest temperatures, and yellow through red indicates that ablative temperatures have been reached. A 1-year post-treatment biopsy was negative and the patient’s PSA has fluctuated between 0.2 ng/ml and 0.6 ng/ml over 3 years post-treatment, with most recent PSA at 0.4 ng/ml.
