Toronto – October 12, 2026 -- Men treated with whole-gland TULSA Procedure showed no median change in penile length at one month, compared with a median 0.65 cm reduction after robotic radical prostatectomy (RP), according to new data from the Level 1 CAPTAIN randomized controlled trial, Profound Medical Corp. (NASDAQ:PROF; TSX:PRN) announced.
Mixed-effects model shows 0.42 cm between-arm difference
The between-arm difference in change in penile length, estimated from a mixed-effects model, was 0.42 cm (p<0.001), which Profound describes as statistically significant. Xiaosong Meng, MD, PhD, Assistant Professor in the Department of Urology at UT Southwestern Medical Center, presented the results at the Society of Robotic Surgery Annual Meeting in Fort Lauderdale, Florida.
