Concomitant Trans-Perineal Prostate Biopsy and Ablation (Bioblation) for Prostate Cancer (Bioblation)

April 9, 2026 updated by: Ahmed Al-Lithi, Benha University

Validation of Concomitant Trans-Perineal Prostate Biopsy and Ablation (Bioblation) for Symptomatic (LUTS) Selected Most Probably Low and Intermediate Risk PCa Patients

This prospective study aims to validate the clinical outcomes of performing a concomitant trans-perineal prostate biopsy and laser ablation (termed "Bioblation") during a single session. The intervention is designed for symptomatic patients presenting with lower urinary tract symptoms (LUTS) who are highly suspected to have low to favorable intermediate-risk prostate cancer. By combining diagnosis and targeted treatment under local anesthesia, this approach seeks to facilitate early relief of severe symptoms and a rapid return to daily activities. Ultimately, the study evaluates whether this combined procedure decreases the patient's exposure to multiple, temporally separated interventions without compromising oncological safety or efficacy.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Bioblation Group
Patients with severe lower urinary tract symptoms (LUTS) and suspected low to favorable intermediate-risk prostate cancer undergoing concomitant trans-perineal prostate biopsy and laser ablation in a single session
Procedure: Bioblation
The procedure is performed under local anesthesia and a prostatic nerve block. Under real-time transrectal ultrasound (TRUS) visualization, four biopsy cores are taken transperineally from each suspected focal lesion, alongside systematic biopsies of the transitional zones. Immediately following the biopsy, 18G Chipa needles are inserted transperineally to pass 300-micron laser fibers to the target site. Using the Elesta system, 7W of laser energy is delivered via MRI-guided cognitive fusion to induce thermal coagulative necrosis of the tumor.

  • Elesta laser system

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in International Prostate Symptom Score (IPSS)
Time Frame: Baseline, 1, 3, 6, 9, and 12 months post-procedure
The IPSS is a validated questionnaire used to assess the severity of lower urinary tract symptoms (LUTS). The total score ranges from 0 to 35, where 0-7 indicates mildly symptomatic, 8-19 moderately symptomatic, and 20-35 severely symptomatic. A decrease in the score indicates an improvement in symptoms.
Baseline, 1, 3, 6, 9, and 12 months post-procedure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Maximum Urinary Flow Rate (Q-max)
Time Frame: Baseline, 1, 3, 6, 9, and 12 months post-procedure
Maximum urinary flow rate will be measured using uroflowmetry to assess functional improvement in urination. It is measured in milliliters per second (mL/sec). A higher value indicates better urinary flow and less obstruction.
Baseline, 1, 3, 6, 9, and 12 months post-procedure
Change in Post-Void Residual (PVR) Urine Volume
Time Frame: Baseline, 1, 3, 6, 9, and 12 months post-procedure
PVR will be measured via ultrasound to determine the volume of urine remaining in the bladder immediately after urination. It is measured in milliliters (mL) or cubic centimeters (cc). A lower volume indicates better bladder emptying.
Baseline, 1, 3, 6, 9, and 12 months post-procedure
Change in Prostate Volume
Time Frame: Baseline, 1, 3, 6, 9, and 12 months post-procedure
Total prostate gland volume will be assessed using transrectal ultrasound (TRUS) or multiparametric MRI. It is measured in cubic centimeters (cc) or milliliters (mL). A decrease in volume indicates a reduction in gland size following the ablation procedure.
Baseline, 1, 3, 6, 9, and 12 months post-procedure
Change in Total Serum Prostate-Specific Antigen (PSA)
Time Frame: Baseline, 1, 3, 6, 9, and 12 months post-procedure
Measurement of total serum PSA levels (in ng/mL) to monitor oncological control, disease status, and therapeutic response following the focal ablation of the suspected prostate lesions.
Baseline, 1, 3, 6, 9, and 12 months post-procedure
Incidence of Procedure-Related Complications
Time Frame: Up to 12 months post-procedure
The occurrence, type, and severity of post-operative adverse events (such as hematuria, acute urinary retention, fever, or signs of infection) will be recorded to evaluate the safety profile of the concomitant biopsy and ablation procedure.
Up to 12 months post-procedure
