Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 80 years
  • Men only
  • No healthy volunteers
  • Adult, Older adult

Study population: The patients included in this study will be allocated into 2 groups, a PLASMA arm and a HOLEP arm, depending on the technique used by each of the surgeons in the study, which depends on the technology available in the health care institution. Therefore, no randomisation is possible for this study. A balance of centres between those performing the PLASMA technique and those performing the HOLEP technique is set up (2 centres for each technology) in order to allow the inclusion of a comparable number of patients in each group. Recruitment will take place through the urology consultation flow or through inpatient referrals. In the latter case, patients must have been seen at least once in consultation by an investigating physician prior to the intervention to introduce them to the study.

Who may be able to join

  • Men aged 18 years or more and less than 80 years,
  • Prostate volume 30-80 cc inclusive
  • Patient who has failed medical treatment for his prostate adenoma,
  • Indication for prostate enucleation (HOLEP or PLASMA)
  • Patient who was informed of the study and did not object

Who cannot join

  • Patient with a diagnosis of prostate cancer,
  • Patient requiring monopolar or bipolar endoscopic resection,
  • Patient under legal protection

About this study

Official title: Observational Study to Compare Two Prostate Laser Enucleation Techniques (Photo-vaporization of the Prostate (PLASMA) Versus HoLEP) in Terms of Overall Post-operative Urinary Incontinence

Benign prostatic hypertrophy or prostatic adenoma is a benign tumour that develops in the central part of the prostate. Prostatic adenoma can result in the progressive appearance of a difficulty in evacuating the bladder or frequent urges to urinate and other complications (lithiasis, haematuria, urinary retention, etc.). Surgery is indicated when medical treatment is no longer effective and in the case of complications. The endoscopic techniques for treating prostate adenoma, PLASMA and HOLEP, are recognised and recommended by the French Association of Urology and the European Association of Urology (EAU) as Gold Standard techniques in view of the good results reported in the literature, the low rate of complications compared to the other techniques, and the reduced hospitalisation rate. For prostate volumes less than 80cc, there is no difference between HOLEP and Bipolar Plasma Enucleation of the Prostate (BTUEP) in terms of International Prostate Symptom Score (IPSS), Qmax, and reoperation rate at 12 months. The surgeon's experience is the most important factor influencing the risk of complications for HOLEP. Urinary incontinence after HOLEP according to Houssin et al. is 14.5% at 3 months and 4.2% at 6 months, the risk factors identified were surgeon experience and the existence of diabetes. Comparative evaluation of the two techniques is less frequent, hence the interest of our prospective and multicentre study. In this study, the investigators hope to demonstrate a better outcome of the PLASMA technique in terms of post-operative residual urinary incontinence.

Read the detailed description

Benign prostatic hyperplasia or prostatic adenoma is a benign tumour that develops in the central part of the prostate. It usually affects men over the age of 50, with the incidence of the disease increasing with age. Prostatic adenoma may result in the progressive appearance of bladder weakness or frequent urination and other complications (lithiasis, haematuria, urine retention, etc.).

Surgery is indicated when medical treatment is no longer effective and in the case of complications.

Among the surgical interventions, several techniques are currently offered to the patient:

  • transurethral monopolar resection
  • transvesical adenomectomy
  • HOLEP laser enucleation of the prostate
  • Bipolar resection and enucleation using the Bipolar Plasma Enucleation of the Prostate (BTUEP) technique, also known as "PLASMA".

Transurethral monopolar resection is considered an obsolete technique by the learned societies, in particular because of the risk of transurethral resection of the prostate syndrom (vital risk for the patient in the event of reabsorption of the peroperative glycocoll washing liquid), the per and postoperative haemorrhagic risk, especially in patients who are on anticoagulants and/or anti-aggregants and who cannot be stopped for the prostatic procedure.

Transvesical adenomectomy has a higher bleeding risk due to the fact that it is performed in open surgery, which is much more invasive. There is a transfusion rate of 7-14%. The rate of urinary incontinence can be as high as 10% and the rate of urethral stenosis 6%.

Compared to BTUEP or HOLEP, HOLEP has a longer operating time, longer catheterisation and hospitalisation time and a higher transfusion rate for transvesical adenomectomy.

Adenomectomy should therefore only be offered if the centre has neither HOLEP nor BTUEP according to European recommendations.

The new endoscopic techniques for treating prostate adenoma, PLASMA and HOLEP, are recognised and recommended by the French Association of Urology and the European Association of Urology (EAU) as Gold Standard techniques in view of the good results reported in the literature, the low rate of complications compared with the other techniques described above, and the reduced hospitalisation rate.

For prostate volumes less than 80cc, there is no difference between HOLEP and BTUEP in terms of IPSS, Qmax, and reoperation rate at 12 months.

Compared to conventional transurethral resection of the prostate, there was a significant improvement in International Prostate Symptom Score (IPSS), quality of life (QoL), and Qmax for the BTUEP technique. These results are valid at 36, 48 and 60 months. BTUEP was also superior in terms of haemoglobin loss, duration of irrigation, duration of catheterisation and duration of hospitalisation, as well as a reduction in the post-operative retention rate and the transfusion rate. There is no greater risk of incontinence with BTUEP than with transurethral resection of the prostate.

For HOLEP, there was no significant difference in Qmax or reoperation rate compared to MTURP. Compared to BTUEP, there was no significant difference in IPSS, QOL, and Qmax according to two meta-analyses. Functional outcomes at 7 years follow-up between HOLEP and monopolar transurethral resection of the prostate (MTURP) are comparable and HOLEP has an advantage in catheterisation time, hospitalisation, loss of haemoglobin, no more urethral strictures or urge incontinence.The experience of the surgeon is the most important factor influencing the risk of complications in HOLEP.

Urinary incontinence after HOLEP according to Houssin et al. is 14.5% at 3 months and 4.2% at 6 months, the risk factors identified were surgeon experience and the existence of diabetes.

In a comparative study of HOLEP and PLASMA, 19% of incontinence was found at 3 months for HOLEP against 6% for PLASMA.

Other a study found lower rates of 5.7% for HOLEP. Based on these data, the functional outcomes of PLASMA and HOLEP are comparable. However, comparative evaluation of the two techniques is less frequent in studies which are generally retrospective or monocentric, hence the interest of our prospective and multicentric study.

By comparing two reference techniques of prostatic enucleation, HOLEP and PLASMA, the investigators hope to demonstrate in this study a better result of the PLASMA technique in terms of post-operative residual urinary incontinence. If this is demonstrated, PLASMA could overtake HOLEP, with a significantly lower material cost and a reduced learning curve.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PLASMAProcedure or surgery

    The aim is to remove the prostatic adenoma by enucleation, i.e. to pass through the plane between the adenoma and the prostatic capsule, as opposed to resection, which also consists of removing the adenoma, but by making small cuts in the prostatic tissue, without necessarily reaching this anatomical plane between the adenoma and the capsule. This means removing less adenoma and therefore increasing the risk of adenomatous regrowth in the long term or obtaining worse results than enucleation in the short to medium term.

    The other advantage of using this approach is that it reduces intra- and post-operative bleeding and does not require the systematic discontinuation of anti-aggregating or anticoagulant treatments prior to the operation. The field of indications is thus potentially enlarged.

Study groups in NCT05157724
Study groupRoleWhat they receive
PLASMAThis technique consists of an endoscopic intervention, through the natural route (urethra).
Receives: Procedure: PLASMA
HOLEPThis is a recent and difficult technique of endoscopic prostate enucleation, requiring a greater learning curve for the operators compared to PLASMA. The principle remains the same technically as the PLASMA procedure, the energy used is not electrical energy, but a laser. Once the adenoma has been enucleated, it can only be removed by a morcellator (additional material) which can lead to complications such as bladder perforation. This is a blade that rotates in a tube that has to cut the adenoma once it has been freed from the prostate when it is in the bladder and it can happen that this blade catches on the bladder wall and causes a bladder wound or even a perforation.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall urinary incontinence (including stress urinary incontinence and urgency) between the two prostate enucleation procedures PLASMA and HOLEP at 3-month visit (time frame: At 3 months post surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05157724, which also lists 26 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Feb 2024.
