Holmium Laser Enucleation of the Prostate: Modified Two-Lobe Technique versus Traditional Three-Lobe Technique-A Randomized Study.

ABSTRACT:

Background

Holmium laser enucleation of the prostate (HoLEP) is considered the standard endoscopic treatment of benign prostatic hyperplasia (BPH), but traditional HoLEP surgery will cause some postoperative complications. This study was attempted to evaluate the safety and efficacy of modified two-lobe technique versus traditional three-lobe technique of HoLEP focusing mainly on incidences of retrograde ejaculation (RE) and urinary incontinence (UI).

Methods

From March 2014 to February 2017, 191 men with BPH were randomly assigned to two groups: 97 underwent modified two-lobe technique; 94 underwent traditional three-lobe technique. All patients were followed up for 12?months. Primary outcomes were incidences of RE and UI, and secondary outcomes were international prostate symptom score (IPSS), quality of life (QOL), maximal urine flowing rate (MFR), and residual urine among the studied patients.

Results

Compared with the traditional technique, patients in the modified group had a statistically significant decrease in frequency of UI (1.03% vs 8.51%, p=0.036) and RE in the 6^th month (33.33% vs 63.64%, p=0.030) and 12^th month (13.33% vs 50%, p=0.034) and a significant increase in ejaculatory volume in the 6^th month (p=0.050) and 12^th month (p=0.003). Besides, the modified HoLEP was more beneficial to patients according to the change of QoL score at 1 month (p=0.002), 3 months (p=0.004), 6 months (p=0.026), and 12 months (p=0.015).

Conclusions

The modified two-lobe technology of HoLEP reduced the incidence of RE and UI, which improved the quality of life of the patients after surgery compared to the traditional three-lobe technology. This trial is registered with ChiCTR1800018553.

Project description:ObjectiveTo demonstrate how bladder ultrasound can be useful in completing morcellation during difficult Holmium Laser Enucleation of the Prostate (HoLEP). As HoLEP has emerged as a standard of care for the treatment of benign prostatic hyperplasia, multiple studies have reported the potentially catastrophic complication of bladder injury during morcellation. This video aims to assist any urologist performing HoLEP by providing step-by-step instruction for using ultrasound to complete morcellation safely.MethodsEnucleation is performed using a 26-French continuous flow scope, off-set laser bridge with a laser stabilization catheter, and a 550 µm holmium laser fiber. Once the median and lateral lobes have been enucleated, the outer sheath is removed and the nephroscope is inserted to facilitate morcellation. Under dual inflow irrigation, the Piranha morcellator (Richard Wolf, Knittlingen, Germany) is introduced and set to the manufacturer's recommended settings of 1500 rpm. A 3.5-MHz convex abdominal ultrasound transducer (Hitachi Prosound Alpha 7; Hitachi Aloka Medical America, Wallingford, CT) under B-mode is used to visualize the bladder, predominantly in the sagittal orientation. Morcellation proceeds under simultaneous ultrasound and direct cystoscopic guidance.ResultsThe distended bladder is visualized concurrently with the ultrasound and via the nephroscope as the Piranha engages the adenoma and begins morcellation. Once the adenoma is engaged, the operator then drops their hands to place the morcellator in the center of the bladder. Ultrasound provides real-time feedback as to the location of the morcellator in relation to the adenoma and bladder.ConclusionThis video highlights the use of intraoperative bladder ultrasound as a visual aid to assist during the morcellation portion of HoLEP. This proof of concept demonstrates that ultrasound can be an additional tool to utilize during difficult cases when cystoscopic visualization during morcellation is limited.

Project description:BACKGROUND: Holmium laser enucleation (HoLEP) in surgical treatment of benign prostate hyperplasia (BPH) potentially offers advantages over transurethral resection of the prostate (TURP). METHODS: Published randomized controlled trials (RCTs) were identified from PubMed, EMBASE, Science Citation Index, and the Cochrane Library up to October 10, 2013 (updated on February 5, 2014). After methodological quality assessment and data extraction, meta-analysis was performed using STATA 12.0 and Trial Sequential Analysis (TSA) 0.9 software. RESULTS: Fifteen studies including 8 RCTs involving 855 patients met the criteria. The results of meta-analysis showed that: a) efficacy indicators: there was no significant difference in quality of life between the two groups (P>0.05), but compared with the TURP group, Qmax was better at 3 months and 12 months, PVR was less at 6, 12 months, and IPSS was lower at 12 months in the HoLEP, b) safety indicators: compared with the TURP, HoLEP had less blood transfusion (RR 0.17, 95% CI 0.06 to 0.47), but there was no significant difference in early and late postoperative complications (P>0.05), and c) perioperative indicators: HoLEP was associated with longer operation time (WMD 14.19 min, 95% CI 6.30 to 22.08 min), shorter catheterization time (WMD -19.97 h, 95% CI -24.24 to -15.70 h) and hospital stay (WMD -25.25 h, 95% CI -29.81 to -20.68 h). CONCLUSIONS: In conventional meta-analyses, there is no clinically relevant difference in early and late postoperative complications between the two techniques, but HoLEP is preferable due to advantage in the curative effect, less blood transfusion rate, shorter catheterization duration time and hospital stay. However, trial sequential analysis does not allow us to draw any solid conclusion in overall clinical benefit comparison between the two approaches. Further large, well-designed, multicentre/international RCTs with long-term data and the comparison between the two approaches remain open.
