Prostatic Disease Center

Advanced Prostate Care with Aquablation Therapy

At our Prostate Center, we provide expert care for prostate cancer and benign prostatic hyperplasia (BPH). With advanced technology—including the latest da Vinci® Surgical System —our team delivers safe, precise, and minimally invasive treatments. By combining innovation with compassionate care, we create an environment where every patient can feel confident and supported.

1. Advanced Diagnostic Technology－Early detection. Accurate results.

Our center uses the latest diagnostic tools, including MRI–ultrasound fusion biopsy and PSMA-PET scans. These advanced methods allow highly precise detection of prostate cancer and its spread, enabling earlier diagnosis and more effective treatment.

2. Robotic-Assisted Surgery－Precision through innovation.

We perform minimally invasive laparoscopic surgery using the latest da Vinci® Surgical System. Our procedures are led by highly experienced urologists certified as instructors in robotic surgery. Compared to traditional open surgery, Da Vinci surgery offers clear advantages: less bleeding, less pain, and faster recovery.

3. Radiation Therapy－Powerful treatment, fewer side effects.

Our center is equipped with cutting-edge proton beam therapy and intensity-modulated radiation therapy (IMRT). IMRT delivers radiation tailored to the exact shape of the prostate, maximizing effectiveness while minimizing impact on surrounding tissues.

4. Aquablation Therapy (AQUABEAM® Robotic System)－A new era in prostate treatment.

In 2023, we became the first hospital in Japan to introduce the AQUABEAM® Robotic System, the world’s first fully automated surgical robot for the prostate. This breakthrough therapy has drawn attention as a way to restore the prostate to a more youthful condition, offering hope to patients seeking safe and effective treatment.

Uses high-velocity saline water jets to gently remove tissue
Unlike traditional electrosurgical methods, it causes no heat damage, protecting the nerves around the prostate responsible for erections
No impact on the urinary sphincter or ejaculatory ducts, preserving urinary and reproductive function
These features make the procedure safe even for younger patients
Less bleeding and faster recovery

AQUABEAM® Robotic System

During the procedure, doctors map the prostate using ultrasound, and the robot performs the resection with remarkable precision. Each session lasts about five minutes, repeated twice, making the overall surgery significantly shorter while ensuring safety and effectiveness.

Diagnostic Tests

PSMA-PET/CT

A highly accurate PET/CT scan used to identify metastatic sites of prostate cancer.
*This test is offered as a self-paid option.

Phi (Prostate Health Index)

A blood tumor marker that is more sensitive than PSA for detecting prostate cancer in the “gray zone” when PSA is below 10 ng/mL.

MRI

Performed before prostate biopsy to locate cancerous lesions and assess any spread to surrounding organs.

Prostate Biopsy

Conducted under anesthesia to collect tissue from the prostate for cancer diagnosis, performed via the perineum with transrectal ultrasound guidance, and typically requires a two-night hospital stay.

Frequently Asked Questions

Is a prostate cancer biopsy painful?

A prostate needle biopsy is performed under local anesthesia, which helps reduce pain. Any discomfort after the procedure is usually minimal.

How long does prostate cancer treatment take?

It depends on the treatment method. For robotic-assisted surgery (da Vinci® Surgical System), hospitalization is about 10 days. Radiation therapy usually takes around 3 to 8 weeks.

How long is the treatment for benign prostatic hyperplasia (BPH)?

With the Aquablation robotic system, hospitalization is about 5 days.

Will there be restrictions on daily life after treatment?

It depends on the type of treatment, but many patients can return to normal daily activities within a few days to a few weeks. Your doctor will give you detailed instructions and advice for your specific case.
