ThuLEP vs HoLEP — Key Differences

ThuLEP (Thulium fiber Laser Enucleation of the Prostate) uses the thulium fiber laser (TFL) operating at 1940 nm in continuous-wave mode. Unlike the pulsed holmium laser, the continuous emission of TFL creates a more uniform tissue interaction with an excellent haemostatic effect — resulting in a cleaner surgical field and often shorter catheter times.

The enucleation principle is identical to HoLEP: the obstructing adenoma is dissected off the surgical capsule endoscopically, morcellated, and aspirated. No external incisions are required.

Recovery

Discharge the day after surgery in most cases. No external wounds. Return to desk work within 48 hours, full activity in 1–2 weeks. Follow-up uroflowmetry and IPSS assessment at 4 weeks.

Frequently Asked Questions — ThuLEP

What is the key difference between ThuLEP and HoLEP?

Both procedures share the same enucleation principle — the obstructing adenoma is dissected off the prostatic capsule endoscopically, morcellated, and aspirated without any skin incision. The difference lies in the energy source: HoLEP uses a pulsed holmium laser, while ThuLEP uses a thulium fiber laser (1940 nm, continuous-wave). The continuous-wave emission provides more uniform tissue interaction and excellent haemostasis of small vessels, resulting in a cleaner operative field and — in many series — a shorter catheter duration.

What are the advantages of thulium laser over holmium for prostate surgery?

The thulium fiber laser's continuous-wave mode produces precise coagulation of small vessels during dissection, yielding less intraoperative bleeding and a cleaner view. Its 1940 nm wavelength is highly absorbed by water, allowing precise tissue ablation with minimal collateral thermal spread. These properties can translate to a catheter duration as short as 12 hours and reduced post-operative irritative symptoms.

Is ThuLEP suitable for very large prostates?

Yes. Dr. Samer Morsy's published series (Cent Eur J Urol 2023) specifically demonstrated ThuLEP efficacy in prostates over 80 g using a low-power protocol, with one-year follow-up confirming durable IPSS and Qmax improvement. Like HoLEP, ThuLEP is size-independent and offers complete adenoma removal regardless of gland volume.

What is the recovery like after ThuLEP?

Recovery is rapid. The urethral catheter is removed at 12–24 hours, and most patients are discharged the following morning. There are no external wounds. Patients return to desk work within 48 hours and full physical activity within 1–2 weeks. A follow-up appointment at 4 weeks includes uroflowmetry and IPSS re-assessment to confirm functional improvement.

Does ThuLEP affect sexual function?

Retrograde ejaculation is expected in the majority of ThuLEP patients — as with HoLEP — and is discussed in detail during pre-operative counselling. Erectile function is generally unaffected as no neurovascular structures outside the capsule are disturbed. Most patients report that their sexual quality of life returns to baseline within a few weeks of surgery.
