HoLEP for Men in Urinary Retention

What urinary retention means

Urinary retention is when the bladder cannot empty on its own. It can be acute (sudden, painful, no urine passed) or chronic (gradual, less painful, large residual).

Acute retention is a medical emergency that needs a catheter at once. Chronic retention may be picked up during routine assessment of slow flow and incomplete emptying.

Both can be caused by BPH when the outlet is severely obstructed.

Why HoLEP fits this situation

HoLEP opens the outlet widely and removes the obstructing tissue. The capsule plane allows a complete job even in very large glands.

Men in retention often have had BPH for years. By the time retention sets in, the gland tends to be large.

HoLEP handles large glands without a change in technique, which is why many surgeons offer it as a go-to for retention.

What the evidence shows

A 2026 study compared HoLEP in men with and without catheter-dependent acute urinary retention[¹]. The study reported similar functional outcomes across both groups, with slightly longer catheter time in the retention group but no difference in long-term symptom relief.

That fits clinical experience. For many men in retention, HoLEP has been followed by long-term catheter-free voiding in published cohorts, though individual outcomes depend on bladder function and other factors.

Bladder recovery after long-standing retention may take weeks, and pre-operative counselling covers this.

Pre-op steps

Urine culture is taken before surgery because long-standing catheters can carry low-grade infection. Targeted antibiotics may be given on the day.

Blood tests check kidney function. Chronic retention can strain the kidneys, and kidney numbers sometimes need a period of bladder drainage before they settle.

A scan checks for bladder stones or upper-tract changes that might need separate attention during the operation.

After the catheter is removed

Bladder contractility — the strength of the pushing muscle — needs time to wake up after long retention. Small weak streams in the first days can improve over weeks.

Some men have persistent weak contractility if retention was very long-standing. In those cases, the bladder, rather than the outlet, is now the limiting factor.

Your team can assess this with a flow test and a scan, and can plan the next steps.

Continence after HoLEP in retention

Temporary leaks are possible in the first weeks after catheter removal. They tend to follow the same pattern as after a standard HoLEP.

A bladder that was stretched for months may be more prone to urgency in early recovery. This usually settles as the bladder returns to a normal size.

Pelvic floor exercises help here too.

A word on expectations

Not every man in retention recovers a full normal stream. The bladder's years of extra work may have left lasting changes.

HoLEP, however, removes the outlet obstruction. That is the part the operation can fix.

An honest pre-op conversation sets expectations and opens the door to longer-term support if needed.

Plain bottom line

Men in retention with an indwelling catheter are often strong candidates for HoLEP. The operation aims at the outlet, which is the part that the catheter has been bypassing.

Recovery takes time, but many men end the operation catheter-free for the first time in months.
