ABSTRACT Objectives: To compare thulium laser enucleation of prostate (ThuLEP) versus laparoscopic trans-vesical simple prostatectomy (LSP) in the treatment of benign prostatic hyperplasia (BPH). Materials and Methods: Data of patients who underwent surgery for "large" BPH (>80mL) at three Institutions were collected and analyzed. Two institutions performed ThuLEP only; the third institution performed LSP only. Preoperative (indwelling catheter status, prostate volume (PVol), hemoglobin (Hb), Qmax, post-voiding residual volume (PVR), IPSS, QoL, IIEF-5) and perioperative data (operative time, enucleated adenoma, catheterization time, length of stay, Hb-drop, complications) were compared. Functional (Qmax, PVR, %ΔQmax) and patient-reported outcomes (IPSS, QoL, IIEF-5, %ΔIPSS, %ΔQoL) were compared at last follow-up. Results: 80 and 115 patients underwent LSP and ThuLEP, respectively. At baseline, median PVol was 130 versus 120mL, p <0.001; Qmax 9.6 vs. 7.1mL/s, p=0.005; IPSS 21 versus 25, p <0.001. Groups were comparable in terms of intraoperative complications (1 during LSP vs. 3 during ThuLEP) and transfusions (1 per group). Differences in terms of operative time (156 vs. 92 minutes, p <0.001), Hb-drop (-2.5 vs. −0.9g/dL, p <0.001), catheterization time (5 vs. 2 days, p <0.001) and postoperative complications (13.8% vs. 0, p <0.001) favored ThuLEP. At median follow-up of 40 months after LSP versus 30 after ThuLEP (p <0.001), Qmax improved by 226% vs. 205% (p=0.5), IPSS decreased by 88% versus 85% (p=0.9), QoL decreased by 80% with IIEF-5 remaining almost unmodified for both the approaches. Conclusions: Our analysis showed that LSP and ThuLEP are comparable in relieving from BPO and improving the patient-reported outcomes. Invasiveness of LSP is more significant.

ABSTRACT Introduction: Thulium laser VapoEnucleation of the prostate (ThuVEP) is an evolving surgical technique for BPH. Most studies have focused on outcomes in small to medium sized prostates and have originated from Europe and Asia. We sought to describe our experience with ThuVEP for very large prostates in a North American cohort. Materials and Methods: From December 2010 to October 2014, 25 men underwent ThuVEP using the CyberTM® (Quantastem, Italy) thulium laser, all with prostate volume >75mL. Data collected included patient demographics, comorbidities, intraoperative parameters, complications, and post-operative outcomes including maximum flow rate (Qmax), post-void residual (PVR), International Prostate Symptom Score (IPSS), and quality of life score (QoL) in one year of follow-up. Statistical analysis was done using Wilcoxon signed-rank test. Results: At baseline, mean age was 70±9 years and prostate size was 163±62g. Most patients (84%) were in retention and 10 (40%) patients were on anticoagulation. Seven (28%) patients went home the day of surgery (mean hospital stay: 1.2±1.2d). There were 2 intraoperative complications (8%), both cystotomies related to morcellation. Nine patients (36%) experienced a complication, all within 30 days. There were no Clavien ≥III complications. Significant improvements were seen in Qmax, PVR, IPSS, and QoL score at each time interval to 12-months following surgery (all p<0.05). Of 21 patients initially in retention, all were voiding at last follow-up. Conclusions: Our findings suggest that ThuVEP is an effective treatment for BPH in patients with large prostates with sustained results for one year.

PURPOSE: Various articles have previously addressed the introduction of new surgical laser therapies for an enlarged prostate gland causing obstructive symptoms. The objective of this study was to report the feasibility of performing the thulium laser vapo-enucleation of the prostate (ThuVEP) procedure for benign prostatic obstruction in a 1-day surgery. MATERIALS AND METHODS: From September 2011 to September 2013, we conducted a prospective study on patients who underwent ThuVEP in a 1-day surgery. The primary outcomes measured perioperatively included operative time, resected tissue weight, hemoglobin decrease, transfusion rate, postoperative irrigation and catheterization time, and postoperative hospital stay. Also, the preoperative and postoperative International Prostate Symptom Score (IPSS) and results of uroflowmetry performed on the 7th and 30th postoperative days were recorded. All perioperative and postoperative complications were monitored. RESULTS: A total of 53 patients underwent the surgical treatment in a 1-day surgery. Seven patients continued antiaggregant therapy with aspirin. Mean preoperative prostatic adenoma volume was 56.6 mL. Mean operative time was 71 minutes. The average catheter time was 14.8 hours. The peak urinary flow rate on day 7 improved from 9.3 to 17.42 mL/s (p<0.001) and the IPSS improved from 18 to 10.2 (p<0.01). Patients were routinely discharged on the day of catheter removal. No complications were recorded. CONCLUSIONS: ThuVEP can be safely conducted as a 1-day surgical procedure. This strategy results in cost savings. ThuVEP shows good standardized outcomes with respect to improvement in flow parameters and length of bladder catheterization.
