HoLEP for Men on Blood Thinners

Why blood thinners matter for BPH surgery

Blood thinners prevent clots in the heart, the brain, and the legs. They also raise the risk of bleeding during any operation.

For BPH surgery, the inside of the prostate is very vascular. A thinner than usual blood adds to the challenge.

Your team balances the two risks together. Stopping a blood thinner carries its own risk, and sometimes that risk outweighs the surgical bleeding risk.

Why HoLEP suits many men on thinners

The holmium laser seals small vessels as it cuts. That sealing happens at the point of contact, not somewhere else.

Because the surface stays sealed, the amount of blood in the field is often smaller than with older techniques. That advantage carries through to men on blood thinners.

HoLEP is therefore offered to many men who would have been steered toward an open operation in the past.

How the decision is made

Your cardiologist, your anaesthetist, and your urologist talk before the operation. They decide whether the thinner should be continued, paused, or swapped.

The choice depends on what the thinner is for. A recent stroke or a drug-eluting stent is different from long-term aspirin for prevention.

You are part of this conversation. Ask what is being proposed and why.

What the evidence says

A 2024 study compared men who held their blood thinner for HoLEP with men who continued theirs through the operation[¹]. The study covered clopidogrel, warfarin, apixaban, and rivaroxaban in a total of 139 men.

Overall outcomes were similar in both groups. Holding clopidogrel was linked with shorter hospital stays and more same-day catheter removal. Holding warfarin shortened the operation slightly.

The takeaway is that HoLEP can be performed whether the thinner is held or continued, and specific medicines may influence length of stay.

Practical tips before your HoLEP

Bring every medicine bottle to the pre-op clinic. Supplements count too, because some contain blood-thinning ingredients.

Do not stop a prescription on your own. Some thinners need a bridging plan, and stopping them cold can cause harm.

Write the stop-and-start dates down. Pin them to the fridge or save them in your phone.

After the operation

Your team restarts your blood thinner on a schedule that protects both you and the healing prostate. This is usually within a few days.

Mild bleeding after restart is possible. Call for heavy red urine, clots, or trouble passing urine.

A short follow-up at six weeks checks that everything has settled.

Plain bottom line

Being on a blood thinner is not a barrier to HoLEP for many men. The plan — continue, pause, or swap — is shared between cardiology, anaesthesia, and urology, with your voice in the room.
