Study summary

The purpose of this study is to evaluate the safety and outcomes, such as postoperative dysuria (pain during urination), urgency (frequent need to urinate) and urinary incontinence (leaking urine or inability to hold urine), of 3 different HoLEP laser settings.

Read the detailed description

Study subjects will be identified by the clinical team or study coordinator either at the time surgery is scheduled or by review of the surgery schedule. Each subject will be screened for inclusion/exclusion criteria by reviewing the chart. If inclusion/exclusion criteria are met, the patient will be approached by a member of the research team for enrollment into the study. The patient must consent to participate by reviewing a study-specific, IRB-approved informed consent form before any study data is collected.

After informed consent has been obtained, a complete medical history including a detailed urologic history will be obtained prior to the HoLEP procedure. Standard pre-operative laboratory tests will be obtained, including a complete blood count, basic metabolic panel and urine culture.

Pre-operative, intra-operative and post-operative management of the patients included in this study will not differ from routine HoLEP treatment options described in the literature and practiced at our center. All laser settings examined are currently utilized. A complete description of the HoLEP procedure at our institution has previously been described15. Briefly, a 550um Lumenis MOSES fiber will be utilized. A 120W Holmium:YAG laser made by Lumenis will be used. Operatively, the time (minutes) for resection of the tissue will be recorded as "enucleation time". Once enucleation of the tissue has been completed, the time (in minutes) for complete removal of the enucleated tissue will be recorded as "morcellation time". Enucleated tissue can be removed by any means determined necessary by the surgeon, i.e. he/she may use the holmium laser or graspers in combination with the morcellator. Enucleation is typically performed in a stepwise fashion with an initial groove at the 5 and 7 o'clock position, followed by enucleation of the median lobe. The enucleation of the lateral lobes occurs in a bottom up approach. At times depending on patient anatomy an intraoperative decision by the treating surgeon may result in an early apical release. The power settings of 2J of energy will be consistent between the three treatment arms. The frequency will differ from 20Hz, 40Hz and 60Hz between the three treatment arms. After enucleation, hemostasis is performed at a setting of 1J and 20 Hz with a widened pulse width for standard HoLEPs. For patients with a high median bar of bladder neck tissue, a single incision at the bladder neck is made at 6 o'clock. Total amount of laser energy utilized for the procedure will also be recorded.

Note will be made of concurrent procedures done at the time of HoLEP including: bladder calculi managed with cystolithopaxy or upper urinary tract calculi management.

Postoperative, patients will be provided with daily Twilio assessments of their postoperative dysuria, urgency and urgency urinary incontinence (as defined above) until it has resolved and remained symptom free x 3 consecutive days. Follow up Twilio assessments at 1month, 3month and 6months will be performed. Patients will concurrently follow up for standard postoperative face-to-face or virtual visit evaluations with their surgical team at 3months.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 7, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
