Introduction: The aim of this article was to describe, step-by-step, an original technique (T-L technique) in a single centre series of patients who underwent holmium laser enucleation of the prostate (HoLEP) for symptomatic benign prostatic hyperplasia and analyze perioperative outcomes.
Material and methods: We retrospectively analyzed data of 567 patients who underwent HoLEP. The T-L technique consists of a series of incisions used as landmarks, performed at the beginning of the procedure before enucleation. Two T-shape incisions are performed at the level of bladder neck (at the 5-7 and 12 o'clock positions); two L-shape incisions are performed at the level of verumontanum, bilaterally, to mark the apex and to limit the sphincter. Another T-shape incision is performed on the bladder neck at the 12 o'clock position posterior to the level of verumontanum.
Results: The median operative time (OT) was 80 minutes (IQR 64-105); 50 minutes (IQR 35-70) and 15 minutes (IQR 10-20) for enucleation and the morcellation phase, respectively. Conversion to transurethral resection of the prostate (TURP) was necessary in 3/567 (0.6%) patients. Intraoperative complications occurred in 3.4% of cases, capsule perforation occurred in 12/567 (2%) of cases, while bladder perforation during morcellation occurred in 8/567 (1.4%) of cases. Postoperative complications were observed in 20/567 (3.5%) of patients. Specifically, grade 1-2 occurred in 19/567 (3.3%) and grade 3 was recorded in 1/567 (0.2%).
Conclusions: The T-L technique for HoLEP is safe and reproducible with a low rate of perioperative complications. The positioning of some landmarks before enucleation allows for the better orientation during enucleation and could be very useful in case of large prostates.
