Background: We determined the effect of prostate-specific antigen velocity (PSAV) on the surgical outcome of thulium laser enucleation of the prostate (ThuLEP) in patients with benign prostatic hyperplasia (BPH).Methods: A retrospective review was performed of prospectively collected data of patients with BPH who underwent ThuLEP at any time from 2017 to 2019. Patients who had undergone BPH surgery or had prostate cancer previously were excluded, and patients with prostate-specific antigen (PSA) > 4 ng/ml were examined through transrectal ultrasound-guided prostate biopsy to rule out prostatic malignancy. Furthermore, patients were excluded if prostatic malignancy was diagnosed during postsurgery follow-up.Results: The PSA level, International Prostate Symptom Score (IPSS), and quality of life (QoL) of 27 male patients at 3 and 15 months postsurgery differed significantly from those at presurgery; the maximum flow rate (Qmax) and postvoid residual (PVR) significantly differed between 3 months postsurgery and presurgery; and 22 and 5 patients had good to excellent and fair to poor outcomes, respectively, at 15 months postsurgery. Patients were divided into two groups (fair and poor vs. good and excellent outcomes at 15 months postsurgery), which significantly differed with respect to PSAV at 3 months postsurgery (P = 0.04), IPSS presurgery (P < 0.02), surgical length (P = 0.01), and hospitalization duration (P = 0.04). In a receiver operating characteristic (ROC) analysis, the optimal cutoff value of PSAV of −0.52 ng/ml characterized effectiveness at 15 months after ThuLEP, and the area under the curve (AUC), sensitivity, and specificity were 0.82 (P < 0.02), 0.80, and 0.82, respectively. For PSAV < -0.52 and ≥-0.52 ng/ml, the percentages of reduction for IPSS, QoL, Qmax, and PVR were −78.6 and −71.4%, −33.3 and 0.0%, 94.4 and 40.0%, and −85.1 and −38.7%, respectively.Conclusions: Postsurgical PSAV was positively correlated with surgical success, and the PSAV cutoff was −0.52 ng/ml. PSAV can, thus, be used to guide the postsurgical follow-up treatment at 3 months after BPH surgery.

Abstract Background: Several studies described post-operative irritative symptoms after laser enucleation of prostate, sometimes associated with urge incontinence, probably linked to laser-induced prostatic capsule irritation, and potential for lower urinary tract infections We aimed to evaluate the efficacy of a suppository based on Phenolmicin P3 and Bosexil (Mictalase®) in control of irritative symptoms in patients undergoing thulium laser enucleation of prostate (ThuLEP).Methods: In this single-center, prospective, randomized, open label, phase-III study, patients with indication to ThuLEP were enrolled (Dec2019-Feb2021 - Institutional ethics committee STS CE Lazio approval no.1/N-726 - ClinicalTrials.gov NCT05130918). The report conformed to CONSORT 2010 guidelines. Eligible patients were 1:1 randomized. Randomization defined Group A: patients who were administered Mictalase® suppositories twice a day for 5 days, then once a day for other 10 days; Group B: patients who did not receive Mictalase® (“controls”). Study endpoints were evaluated at 15 and 30 days postoperation. Primary endpoint included evaluation of effects of the suppository on irritative symptoms by administering IPSS+QoL questionnaire. Secondary endpoint included evaluation of effects on urinary tract infections by performance of urinalysis with urine culture.Results: 111 patients were randomized: 56 in Group A received Mictalase®. Baseline and perioperative data were comparable. At 15-days, no significant differences were found in terms of IPSS+QoL scores and urinalysis parameters. A significant difference in the rate of positive urine cultures favored Group A (p=0.04). At 30-days follow-up, significant differences were found in median IPSS score (6 [IQR 3–11] versus 10 [5–13], Group A vs B, respectively, p=0.02). Urinalysis parameters and rate of positive urine cultures were not significantly different.Conclusions: The present randomized trial investigated the efficacy of Mictalase® in control of irritative symptoms and prevention of lower urinary tract infections in patients undergoing ThuLEP. IPSS improvement 30-days postoperation was more pronounced in patients who received Mictalase®. Lower rate of positive urine culture favored Mictalase® group 15-days postoperatively. The clinical trial has been registered on ClinicalTrials.gov on November 23rd, 2021 – Registration number NCT05130918.

Aim: The aim of our study is to examine the learning curve of HoLEP and to discuss our results in the light of the literature. Methods: 100 patients who had LUTS resistant to medical treatment and complicated BPH to whom HoLEP procedure had been administered regardless of the size of the prostate in the last 1 year were analysed retrospectively. To evaluate the learning curve, the patients were classified into 4 main groups of 25 consecutively operated patients beginning from the first case. The 4 main groups were divided into 2 subgroups including patients who had prostate volume below or above 80 grams. Results: The mean age of the 100 patients who had HoLEP was 64.5 years. The mean prostate volume was 99.1 cc (45-281 cc). When those with prostate smaller than 80 g are examined, Enucleation efficiency was 0.76 g/min (0.46-0.97 g/min) and Morcellation efficiency was 3.07 g/min (3.34-4 g/min). When those with prostates larger than 80 g are examined, Enucleation efficiency was 0.89 g/min (0.66-1.04 g/min) and Morcellation efficiency was 4.01 g/min (3.93-4.25 g/min). These two parameters were statistically and significantly different in all the 4 groups (p < 0.05). Conclusions: HoLEP still has a steep learning curve. It is necessary to reach the number of cases of 25-50 to reach fundamental experience.

Introduction: Since Holmium laser enucleation of the prostate (HoLEP) was introduced in the 1990s as an endoscopic deobstructing modality for benign prostatic hyperplasia (BPH), several reports have concluded that HoLEP has compared favourably to transurethral resection of prostate (TURP) in relieving Bladder Outlet Obstruction (BOO). However, there has been no consensus regarding the efficacy of surgical management of men with Detrusor Underactivity (DU) and BOO. Methods: We performed a literature search of PubMed, Google Scholar, Scopus, and Web of Science databases. All studies that provided data on the effectiveness of HoLEP in men with BOO and DU were assessed. Data collected included the number of patients, median follow-up, International Prostate Symptom Score (IPSS), Qmax, post-void residual (PVR) and catheter dependency pre- and post-intervention. Results: Nine studies were identified in the literature with a follow-up range between 6 and 60 months. Only one prospective study was identified where investigators performed urodynamic studies (UDSs) before and after the intervention. In addition to a significant improvement of voiding parameters, they reported partial recovery of detrusor muscle contractility in approximately 80% of patients. Furthermore, all other studies reported an improvement in all outcome parameters and proved the efficacy of HoLEP in patients with DU and BOO. Conclusion: The current literature underpins the efficacy of HoLEP in patients with impaired bladder contractility. However, current research is limited and the majority of the published data are retrospective in nature. Therefore, more well-conducted prospective randomised studies are needed to reinforce high-level evidence for this hypothesis. Level of evidence: Not applicable.
