HoLEP operations were performed randomly by 4 surgeons at our institution. General or spinal anesthesia was administered in each case. All procedures were carried out using a 26F resectoscope (System-pro Laser Resectoscope, Olympus, Tokyo, Japan), a 100-W holmium: YAG laser (VersaPulse PowerSuite, Lumenis, Yokneam, Israel), and a 550-μm fiber (SlimLine 550, Lumenis, Yokneam, Israel). Our HoLEP technique was based on the anteroposterior dissection reported by Endo et al. [13 (link)]. Morcellation was performed using a tissue morcellator (VersaCut, Lumenis, Yokneam, Israel). After the procedure, a 22F Foley catheter was placed. The Foley catheter was removed on postoperative day 2. Continence was defined as complete dryness and no pad usage in the present study. Postoperative urinary incontinence included SUI, mixed urinary incontinence, and postvoid dribbling. Urinary incontinence was evaluated in a medical interview. All patients were asked about the presence of urinary incontinence at every medical examination after HoLEP. Follow-up was performed at 1, 3, 6, and 12 months postoperatively.
Slimline 550
Manufactured by Lumenis
Sourced in Israel
The SlimLine 550 is a medical-grade laser system designed for use in various clinical applications. It features a compact and lightweight design, providing a versatile solution for healthcare professionals. The core function of the SlimLine 550 is to generate and deliver laser energy for therapeutic purposes, although the specific intended uses may vary depending on the application and healthcare provider's discretion.

The equipment used was a Holinwon Prima (Wontech Co. Ltd.) with a maximum output of 30 W. LP HoLEP was set to 24 W (2 J, 12 Hz). The HP equipment was a Ho:YAG laser generator (Versapulse PowerSuite; Lumenis Ltd.). The HP HoLEP group was set to 80 W (2 J, 40 Hz). A 550-µm end-firing fiber (SlimLine 550; Lumenis Ltd.) was used in both groups.
HoLEP was performed based on the classical three-lobe technique with an early inverted V-shaped apical mucosal incision, as previously described [15 (link)16 ]. There were no differences in the surgical approach between the high-power and low-power settings.

The equipment for HoLEP comprised a 100-W holmium laser (VersaPulse, Lumenis©), a 550-μm end-firing fiber (Slimline 550, Lumenis©), a modified continuous-flow resectoscope (25F), a tissue morcellator (Piranha, Richard Wolf©), continuous saline irrigation, and a video system. Power settings were adjusted to 1.9 J at 53 Hz.
All procedures were performed by experienced surgeons (TM, PG), or under close supervision (SM), using a 2- or 3-lobe technique under general anesthesia. Technical details have been described previously [14 (link), 15 (link)]. Following enucleation, the prostate-tissue was recovered from the bladder using a morcellator and obtained for histological analysis. Coagulation was achieved by defocusing the laser fiber. We performed bipolar coagulation of the entire prostatic fossa and established continuous bladder irrigation. According to our standard protocol, bladder irrigation was gradually reduced on postoperative (po) day 1; catheter-removal took place on po day 2, with a subsequent assessment of Qmax and PVR. Patients were discharged on po day 3 without specific medication. Follow-up was performed 2 months after surgery including PSA, PVR and uroflowmetry.

Patients who underwent HoLEP with full UDS data were enrolled in this study. Patients with LUTS owing to BPH and who were also suspected of having prostate cancer underwent prostate biopsies first, and only patients without cancer were recommended for HoLEP. The surgical procedures carried out were as those described previously [12 (link)]. The laser setting was 72–100 W (1.8–2.5 J and 30–40 Hz). The HoLEP equipment included a high power 100-W Ho:YAG laser (VersaPulse Select; Lumenis Inc., Yokneam, Israel), a 550-μm fiber (SlimLine 550; Lumenis Inc.), a modified 26-Fr Storz continuous-flow resectoscope with a working element for stabilizing the laser fiber, a Storz rigid nephroscope, and a tissue morcellator (VersaCut system; Lumenis Inc.). Catheter indwelling time after HoLEP was 1–3 days as a rule. We herein refer to mentorship as the surgery with help by mentor as mentioned above [13 (link)].

A 100 W holmium:yttrium-aluminium-garnet (YAG) laser (Versapulse, Lumenis Inc., Santa Clara, CA, USA) with a 550-μm end-firing flexible fibre (SlimLine™ 550, Lumenis Inc.) was used. A continuous flow 26-F resectoscope (Karl Storz, Tuebingen, Germany) was used for all procedures.
The enucleation phase of HoLEP was performed as previously described [9] . After prostate enucleation, adenoma retrieval was routinely performed using a tissue morcellator [2] ; however, in the absence of morcellator cutting blades or morcellator device malfunction, non-morcellation approaches were used. Moreover, if there was concomitant urological pathology this might also be an indication to change our surgical plan regarding the tissue retrieval approach.
Retrieval of the prostate adenoma was performed as follows:

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
