T2-weighted sequences along the axial (a) and sagittal (c) plane at month 12 after transperineal prostate laser ablation (TPLA) in a 70-year-old patient in comparison with the same sequences (b, d) in a 68-year-old patient 12 months after transurethral resection of the prostate (TURP). After TPLA, a horseshoe-shaped hyperintense fluid collection in the transitional gland is well emarginated by the prostate pseudocapsule. The urethra is visible as a hyperintense spot inside the solid stromal adenoma core with reduced compression from the hypertrophic central gland. Both bladder neck and urethra morphology are preserved and therefore bladder function and ejaculation are preserved as well. After transurethral resection of the prostate (TURP), the bladder neck is wedged into the surgical cavum. The urethra is no longer visible. Bladder function and ejaculation are impaired
