Interventions
Aquablation Therapy
The AquaBeam Robotic System and the HYDROS Robotic System utilize high-velocity sterile saline waterjet to resect prostate tissue, guided by real-time visualization through cystoscopy and transrectal ultrasound imaging. This minimally invasive surgical procedure is called the Aquablation therapy.
Active Surveillance
Active surveillance is a management strategy for men with low- and favorable intermediate-risk localized prostate cancer that involves close monitoring with curative intent, reserving treatment for evidence of disease progression. Monitoring typically includes serial PSA testing, periodic prostate MRI, and repeat biopsies at scheduled intervals, with intervention triggered by evidence of disease progression.
