Anaesthesia for HoLEP

Two common choices

HoLEPs are commonly done under general anaesthesia (GA) or spinal anaesthesia. The anaesthetist and the surgeon agree on the plan with you at pre-op.

GA puts you fully asleep through a combination of intravenous and inhalation medicines. A breathing tube supports your airway.

Spinal anaesthesia numbs the lower half of your body through a small injection in the lower back. You stay awake while sensation below the chest is reduced.

What you notice with general anaesthesia

You are asked to breathe oxygen through a mask, then an intravenous medicine sends you to sleep within a minute. The next thing you remember is waking up in recovery.

Awareness of the operation is rare, and memory of it is unusual.

Common after-effects include mild sore throat from the breathing tube and brief drowsiness that wears off over an hour.

What you notice with spinal anaesthesia

An anaesthetist injects a local anaesthetic into the spinal fluid through a thin needle. The injection takes about a minute and is done with you sitting up or lying on your side.

Within minutes, your legs feel heavy and warm, and the sensation in your lower half fades. Sensation during the operation is typically absent, though you may hear conversation.

Spinal blocks wear off over two to four hours. You regain leg movement gradually and can walk once sensation is fully back.

How blood pressure matters during HoLEP

Blood pressure during the operation shapes bleeding on the cutting surface. A 2026 study looked at intraoperative hypotension during HoLEP and its effect on hemostasis[¹].

The team aims to keep blood pressure in a range that supports your organs without increasing bleeding. Small adjustments are common throughout the procedure.

This is one of the reasons continuous monitoring is central to safe anaesthesia.

Which to choose

The choice is driven by your health, the expected length of the operation, and your preference. A cardiac history, severe reflux, or sleep apnoea may tilt the balance toward a spinal.

Men who are anxious about being awake during a procedure often choose GA. Men who prefer a quick wake-up with less grogginess often choose spinal.

Your anaesthetist walks you through the pros and cons with your specific history in mind.

Recovery after anaesthesia

After GA, a short stay in recovery monitors breathing and pain. Many men go back to the ward within an hour.

After spinal, you stay in recovery until the block wears off to a safe level. Bladder function returns once sensation does.

Eating and drinking restart when your team is happy. Pain relief is offered as needed.

Risks, in plain terms

Serious anaesthetic complications are rare. The anaesthetist reviews risk factors with you and plans accordingly.

Common mild effects include sore throat after GA and a headache after some spinals. Both usually pass quickly.

Tell your team any time something feels wrong during or after the operation. Early review of small issues is generally easier than later review.

Plain bottom line

GA and spinal both work well for HoLEP. The right choice is made with you, guided by your health and your preference.

The goal of either technique is the same — a steady, well-controlled operation and a smooth wake-up.
