Name of the Procedure:

Ablation of Prostate, Transrectal, High Intensity Focused Ultrasound (HIFU), including Imaging Guidance

Summary

High Intensity Focused Ultrasound (HIFU) is a minimally invasive medical procedure used to treat prostate issues by using focused ultrasound waves to generate heat and destroy targeted prostate tissue. This procedure includes imaging guidance to ensure precise targeting.

Purpose

HIFU is employed to treat conditions such as prostate cancer and benign prostatic hyperplasia (BPH). The goal of the procedure is to eradicate the problematic prostate tissue while minimizing damage to surrounding healthy tissue. Expected outcomes include reduced tumor size or complete tumor removal, alleviation of urinary symptoms, and an overall improvement in quality of life.

Indications

• Prostate cancer (localized)
• Benign prostatic hyperplasia (BPH)
• Men who opt for a non-surgical treatment option
• Patients unsuitable for or unwilling to undergo traditional surgery or radiation therapy

Preparation

• Patients may be advised to fast for several hours before the procedure.
• Blood tests, imaging studies (MRI or ultrasound), and a thorough urological assessment may be required.
• Medication adjustments, particularly blood thinners, may be necessary.
• Bowel preparation (using enemas or laxatives) might be recommended to ensure a clear rectal area for the procedure.

Procedure Description

1. Anesthesia: The patient is usually given regional anesthesia (spinal or epidural block) or general anesthesia.
2. Initial Imaging: Imaging guidance (typically MRI or ultrasound) is utilized to map out the prostate and plan the treatment.
3. Probe Insertion: A transrectal probe, which sends out high-intensity focused ultrasound waves, is inserted into the rectum.
4. Targeting: Using real-time imaging, the physician precisely targets the prostate tissue.
5. Ablation: The HIFU waves heat and destroy the specific areas of the prostate tissue.
6. Completion: The probe is removed, and post-procedure imaging may be conducted to ensure the treatment area is accurately ablated.

Duration

The procedure typically takes between 1.5 to 3 hours, depending on the size and location of the targeted prostate tissue.

Setting

This procedure is performed in a hospital operating room, outpatient clinic, or specialized surgical center with the necessary imaging and HIFU equipment.

Personnel

• Urologist or specialized surgeon
• Anesthesiologist
• Radiologist or imaging specialist
• Nurse(s) and surgical technician(s)

Risks and Complications

• Infection
• Urinary incontinence
• Erectile dysfunction
• Urinary retention
• Rectal fistula (rare)
• Urethral stricture

Complications can generally be managed with medications, catheterization, or additional medical interventions.

Benefits

• Minimally invasive with no surgical incisions
• Reduced hospitalization time
• Faster recovery compared to traditional surgery
• Precise treatment aimed at conserving healthy prostate tissue
• Potentially preserved urinary and sexual function

Benefits are often realized within weeks to months following the procedure, as targeted tissue gradually shrinks and symptoms improve.

Recovery

• Hospital stay is typically brief, often outpatient or 1-day admission.
• Patients may experience mild discomfort, managed with pain medications.
• Foley catheter may be inserted to aid urination for a few days.
• Avoid strenuous activities for several weeks.
• Follow-up appointments are crucial to monitor recovery and evaluate the success of the treatment.

Alternatives

• Radical prostatectomy (surgical removal of the prostate)
• Radiation therapy
• Cryotherapy (freezing prostate tissue)
• Hormone therapy

Each alternative has its own risks, benefits, and suitability depending on individual patient conditions. HIFU is often chosen for its minimally invasive nature and quicker recovery time.

Patient Experience

During the procedure, patients under anesthesia should not feel pain. Post-procedure, there may be mild to moderate discomfort, which can be alleviated with pain medication. Patients may experience temporary urinary symptoms such as frequency, urgency, or mild blood in the urine, which typically resolve over a few weeks. Emotional support and clear communication from the healthcare team can significantly enhance the overall experience.
