Abstract
INTRODUCTION AND OBJECTIVES Prostate magnetic resonance imaging (MRI) is used for prostate cancer (PCa) screening and risk stratification and is helpful for surgical planning for patients undergoing holmium laser enucleation of the prostate (HoLEP). There are few studies investigating the correlation between MRI Prostate Imaging-Reporting and Data System (PIRADS) lesion characteristics and HoLEP pathology and outcomes. METHODS We performed retrospective review of patients who underwent HoLEP between January 2021 and August 2023 by a single surgeon. Preoperative, intraoperative, and postoperative characteristics and outcomes were analyzed for all patients who had a documented preoperative prostate MRI. RESULTS There were 334 patients without a pre-existing diagnosis of PCa and with a preoperative prostate MRI, of which 140 (42%) had at least one PIRADS lesion. There was a total of 203 PIRADS lesions: 91 (45%) in the peripheral zone (PZ), 106 (52%) in the transition zone (TZ), and 6 (2%) not specified. Incidental PCa was noted in 44 (13%) patients at time of HoLEP. Presence or location of lesion was not significantly associated with rate or grade of incidental PCa on pathology. Greater number of lesions and lesion size correlated with longer procedure times. Lesion number, size, or grade were not found to correlate with cancer grade or rate of cancer. CONCLUSIONS Grade, presence, location, size, and number of PIRADS lesions on preoperative prostate MRI for patients with an appropriate prior PCa workup were not significantly associated with incidental PCa or higher PCa grade on HoLEP pathology.

Abstract
BACKGROUND AND OBJECTIVE Histopathological examination of surgical specimens for benign prostatic hyperplasia (BPH) can detect incidental prostate cancer (iPCa). The aim of our study was to develop a predictive model for iPCa diagnosis for patients for whom BPH surgery is being considered. METHODS We conducted a retrospective analysis of medical files for patients who underwent BPH surgery in three academic centers between 2012 and 2022. Patients diagnosed with PCa before surgery were excluded. We calculated the global iPCa rate, and the clinically significant iPCa rate (grade group ≥2). Univariate and multivariable regression models were used to assess factors predictive of iPCa. The area under the receiver operating characteristic curve (AUC) was compared for each risk factor and for the global model. We used χ2 automated interaction detection (CHAID) for decision tree analysis. KEY FINDINGS AND LIMITATIONS We included 2452 patients in the analysis, of whom 247 (10.0%) had iPCa, which was clinically significant in 49/247 cases (20.2%). Multivariable analysis revealed that age and prostate-specific antigen density (PSAD) were independent predictive factors for iPCa diagnosis. The AUC for a model including age and PSAD was 0.65. CHAID analysis revealed that patients with PSAD >0.1 ng/ml/cm3 had an iPCa risk of 23.4% (χ2 = 52.6; p < 0.001). For those patients, age >72 yr increased the iPCa risk to 35.4% (χ2 = 11.1, p = 0.008). Our study is mainly limited by its retrospective design. CONCLUSIONS AND CLINICAL IMPLICATIONS Age and PSAD were independent risk factors for iPCa diagnosis. The combination of age >72 yr and PSAD >0.1 ng/ml/cm3 was associated with an iPCa rate of 35.4%. PATIENT SUMMARY We performed a study to find predictors of prostate cancer for patients undergoing surgery for benign enlargement of the prostate. Our model can identify patients at risk, and diagnose their cancer before surgery. This could avoid unnecessary or harmful procedures.

Abstract
BACKGROUND To evaluate contemporary preoperative risk factors and subsequent postoperative management of incidental prostate cancer (iPCa) and incidental clinically significant prostate cancer (icsPCa, Grade Group [GG] ≥ 2 PCa). METHODS A retrospective cohort of 811 men undergoing Holmium enucleation of the prostate (HoLEP) (January 2021-July 2022) were identified. Advanced preoperative testing was defined as prostate health index (PHI), prostate MRI, and/or negative preoperative biopsy. Descriptive statistics (Whitney-Mann U test, Chi-squared test) and multivariable logistic regression were performed. RESULTS iPCa and icsPCa detection rates were 12.8% (104/811) and 4.4% (36/811), respectively. Advanced preoperative testing (406/811, 50%) was associated with younger age and higher (prostate specific antigen) PSA, prostate volume, and PSA density. On multivariable analysis, PHI ≥ 55 was associated with iPCa (OR 6.91, 95% CI 1.85-26.3, p = 0.004), and % free PSA (%fPSA) was associated with icsPCa (OR 0.83, 95% CI 0.67, 0.94, p = 0.01). GG1 disease comprised the majority of iPCa (65%, 68/104) with median 1% involvement. iPCa patients were followed with active surveillance (median follow up 9.3 months), with higher risk patients receiving prostate MRI and confirmatory biopsy. Three patients proceeded to radical prostatectomy or radiation. CONCLUSIONS In the era of MRI and advanced biomarkers, the majority of iPCa following HoLEP is low volume GG1 suitable for active surveillance. A tentative follow-up strategy is proposed. Patients with PHI ≥ 55 or low %fPSA, even with negative prostate MRI, can consider preoperative prostate biopsy before HoLEP.

Abstract
INTRODUCTION Aquablation and holmium laser enucleation of the prostate (HoLEP) have evolved as established therapeutic options for men with benign prostatic obstruction (BPO). We sought to compare the rates of incidental prostate cancer (iPCa) after aquablation and HoLEP. METHODS At our center, between January 2020 and November 2022, 317 men underwent aquablation, and 979 men underwent HoLEP for BPO. Histopathological assessment of resected tissue was conducted in all cases. If iPCa was detected, the Gleason score and percentage of affected tissue were assessed. Differences in important predictive factors for prostate cancer between study groups were accounted for by additional matched pairs analysis (with matching on age ± 1 year; PSA ± 0.5 ng/mL; and prostate volume ± 5 mL). RESULTS Histopathology revealed iPCas in 60 patients (4.6%): 59 (6.03%) after HoLEP and 1 (0.3%) after aquablation (p = 0.001). Of 60 of incidental cancers, 11 had a Gleason score ≥7 (aquablation: 1/1 [100%]; HoLEP: 10/59 [16.9%]). The aquablation and HoLEP study groups differed in patient age, preoperative PSA, and prostate volume. Therefore, matched pairs analysis (aquablation: 132 patients; HoLEP: 132 patients) was conducted to improve comparability. Also after the matching procedure, significantly fewer iPCas were diagnosed after aquablation than HoLEP (aquablation: 0 [0%]; HoLEP: 6 [4.5%]; p = 0.015). CONCLUSION Significantly fewer iPCas were identified after aquablation than HoLEP procedures. Histopathologic assessment of tissue after aquablation is feasible and may lead to the diagnosis of clinically significant iPCa. Therefore, histopathologic examination of the aquablation resective tissue should not be omitted.

Abstract
Background: Transurethral resection of the prostate (TURP) has been the standard surgical treatment for Benign Hyperplasia of the Prostate (BPH) for decades. Our objective was to evaluate the outcome of our new technique: Monopolar Transurethral Enucleoresection of the Prostate (TUERP) with apical release (bring it all to centre). Methods: A prospective study of all cases undergoing TUERP at a tertiary centre from January 2020 to October 2022 was performed. Patient demographics, intraoperative variables and postoperative results along with follow-up data were collected. Data of all the cases who had completed a one-year follow-up post-surgery were included and analysed. Results: A total of 240 patients with complete data including a one-year follow-up were included. Mean prostatic volume was 55.3 ± 11.6 gm, and 28 (11.67%) cases were >100 gm. The mean operative time was 31.7 ± 7.6, and mean haemoglobin drop at 24 h was 0.73 ± 1.21 gm/dL. The overall complication rate was 16.67%, with only two (0.83%) Clavien-Dindo III complications (haematuria and clots needing evacuation) and the other complications being Clavien-Dindo I/II complications. Sustained improvement at 1 year of follow-up was noted: Qmax: 25.2 ± 5.6 mL/s, IPSS: 4.7 ± 2.5 and PVR: 22.5 ± 9.6 mL. Conclusions: Monopolar TUERP with a modified Nesbit's enucleoresection with apical release can be considered a promising technique, which needs further studies to be validated with appropriate comparisons.

Abstract
OBJECTIVE To determine the incidence of incidental prostate cancer detection (iPCa) after holmium laser enucleation of the prostate (HoLEP). The published rate of iPCa after HoLEP is widely variable from 7% to 23% and we aim to define preoperative risk factors for iPCa to inform risk-adjusted preoperative evaluation for PCa. METHODS Consecutive patients undergoing HoLEP from 2018 to 2022 were included and comprehensive clinical data abstracted from a prospectively maintained database. iPCa was defined as a diagnosis of PCa on pathologic examination of the HoLEP specimen. Patients with and without iPCa were compared with respect to preoperative clinical variables. RESULTS Of 913 HoLEP patients, 183 (20%) were diagnosed with iPCa. Most patients (95%) had a preoperative prostate-specific antigen (PSA), 9% had negative MRI, and 30% had negative prostate biopsy. On multivariable analysis, PSA density (OR 1.06; 95% CI 1.03, 1.10; P < .001), preoperative biopsy status (OR 0.47, CI 0.30, 0.75; P = .002), and current 5-alpha reductase inhibitor use (OR 0.64, CI 0.43, 0.97; P = .034), were associated with iPCa diagnosis. CONCLUSION In a significantly prescreened population, we identified a 20% rate of iPCa after HoLEP. Preoperative characteristics associated with iPCa diagnosis included increasing age, increasing PSA density, and current 5-alpha reductase inhibitor use. However, these factors alone may be of limited clinical utility to prospectively identify patients at high risk of iPCa diagnosis. We suggest and advocate for development of a standardized, risk-adapted evaluation focused on expanded use of imaging and selective biopsy to prioritize identification of clinically significant PCa prior to nononcologic surgery.

Abstract
Objective Prostate cancer (PCa) patients might experience lower urinary tract symptoms as those diagnosed with benign prostatic hyperplasia (BPH). Some of them might be treated for their lower urinary tract symptoms instead of PCa. We aimed to test the effect of PCa versus BPH on surgical outcomes after transurethral prostate surgery, namely complication and mortality rates. Methods Within the American College of Surgeons National Surgical Quality Improvement Program database (2011-2016), we identified patients who underwent transurethral resection of the prostate, photoselective vaporization, or laser enucleation. Patients were stratified according to postoperative diagnosis (PCa vs. BPH). Univariable and multivariable logistic regression models evaluated the predictors of perioperative morbidity and mortality. A formal test of interaction between diagnosis and surgical technique used was performed. Results Overall, 34 542 patients were included. Of all, 2008 (5.8%) had a diagnosis of PCa. The multivariable logistic regression model failed to show statistically significant higher rates of postoperative complications in PCa patients (odds ratio: 0.9, 95% confidence interval: 0.7-1.1; p=0.252). Moreover, similar rates of perioperative mortality (p=0.255), major acute cardiovascular events (p=0.581), transfusions (p=0.933), and length of stay of more than or equal to 30 days (p=0.174) were found. Additionally, all tests failed to show an interaction between post-operative diagnosis and surgical technique used. Conclusion Patients diagnosed with PCa do not experience higher perioperative morbidity or mortality after transurethral prostate surgery when compared to their BPH counterparts. Moreover, the diagnosis seems to not influence surgical technique outcomes.

Abstract
Aims. Histopathologic benign mimickers of prostate cancer have mostly focused on glandular mimics, with non-glandular mimics mainly limited to inflammatory conditions. While there is a paucity of literature recognizing small cystic (presumably artifactual) spaces in transurethral resection specimens, in some instances they can become florid enough to mimic vascular or epithelial neoplasms. Herein, we detailed histologic, immunophenotypic, and clinicopathologic findings in a large series of specimens showing prominent diagnostically confounding cystic spaces. Methods and Results. Sixty specimens were obtained (50 transurethral resections, 7 aquablations, 3 laser enucleations), from 17 different surgeons. Seven specimens had concurrent genitourinary pathology (4 prostatic adenocarcinoma, 1 solitary fibrous tumor, 1 prostatic atypia, 1 urothelial carcinoma in situ). The extent of cystic change among overall tissue examined ranged from 1 mm-8 mm (mean 3.4 mm), with luminal content of cystic spaces characterized as empty (72%), both empty and fluid-like (17%), and both empty and mucin-like (11%; mucin histochemical stain was negative on all specimens). Notable differences in degree of tissue cautery artifact or inflammation was not found. Immunohistochemistry performed on 30 specimens showed cystic spaces negative for S100, ERG, pankeratin, and CD45. Conclusion. Although artifactual in nature, in some instances small cystic spaces encountered in prostatic transurethral resections and more novel related procedures can become florid enough to warrant recognition as a potential diagnostic confounder of vascular or epithelial neoplasms.

Abstract
Our systematic review aimed to assess the effectiveness and suitability of holmium laser enucleation of the prostate (HoLEP) as a treatment for benign prostatic hyperplasia (BPH) in comparison to transurethral resection of the prostate (TURP). We analyzed 12 studies involving male participants aged 45-85 years, all of whom had BPH. In our analysis, we compared HoLEP and TURP, with a focus on several primary outcomes, including postoperative International Prostate Symptom Score (IPSS), postvoid residual (PVR) volume, maximum flow rate (Qmax), and changes in sexual function post-treatment. HoLEP demonstrated advantages in certain aspects when compared to TURP. HoLEP generally resulted in an improved postoperative IPSS in some studies, but not all studies showed a significant difference when compared to TURP. HoLEP was associated with improved Qmax in most studies, but one study found no significant difference between HoLEP and TURP. Patients who underwent HoLEP showed improvement in the PVR volume in some studies, while others found no significant change in the PVR volume with either HoLEP or TURP. Some studies reported a reduction in orgasm and ejaculatory scores following TURP, while no significant changes were observed in erectile function, intercourse satisfaction, and overall satisfaction scores. It is worth noting that previous reviews and meta-analyses had limited data on the effects of HoLEP and TURP on sexual dysfunction. TURP is associated with a higher risk of morbidity and mortality, which has led to its replacement with HoLEP as the gold standard for treating BPH, particularly due to its size-independent applicability. HoLEP also demonstrated greater efficacy in the postoperative period.

Abstract
Prostate cancer (PCa) identified incidentally (iPCa) after surgical treatment for symptomatic benign prostatic hyperplasia (BPH) causing lower urinary tract symptoms (LUTS) is considered low risk by the most current guidelines. Management protocols for iPCa are conservative and are identical to other prostate cancers classified as having favorable prognoses. The objectives of this paper are to discuss the incidence of iPCa stratified by BPH procedure, to highlight predictors of cancer progression, and to propose potential modifications to mainstream guidelines for the optimal management of iPCa. The correlation between the rate of iPCa detection and the method of BPH surgery is not clearly defined. Old age, small prostate volume, and high pre-operative prostate-specific antigen (PSA) are associated with an increased likelihood of detecting iPCa. PSA and tumor grade are strong predictors of cancer progression and can be used along with magnetic resonance imaging (MRI) and potential confirmatory biopsies to determine disease management. In instances that iPCa requires treatment, radical prostatectomy (RP), radiation therapy, and androgen deprivation therapy all have oncologic benefits but may be associated with increased risk after the BPH surgery. It is advised that patients with low to favorable intermediate-risk prostate cancer undergo post-operative PSA measurement and prostate MRI imaging before electing to choose between observation, surveillance without confirmatory biopsy, immediate confirmatory biopsy, or active treatment. Subdividing the binary T1a/b cancer staging into more categories with ranging percentages of malignant tissue would be a helpful first step in tailoring the management of iPCa.

Abstract
Background: Holmium laser enucleation of the prostate (HoLEP) has been used as an effective minimally invasive technique for management of enlarged prostates. We aimed to report the role of HoLEP in prostate cancer (PCa) patients either on active surveillance with bothersome lower urinary tract symptoms (LUTS) or for prostate debulking before radiation therapy and the impact on PCa management plans. Methods: Prospectively maintained database in two institutions was reviewed for patients with localized PCa managed by HoLEP with at least a follow-up of 1 year. We assessed prostate-specific antigen (PSA) trends, effect on international prostate symptom score (IPSS) and further management of PCa. Results: Out of >2000 HoLEP patients, 117 patients with a median follow-up of 30 months were included. Mean (standard deviation) age was 72.3 (±8.3) years with median (interquartile range, IQR) IPPS of 22 (16-28) and median (IQR) PSA at 7.6 (5.3-14.9) ng/mL. Gleason grade group was 1, 2, 3, and 4 in 47 (73.2%), 32 (27.35%), 7 (5.9%), and 4 (3.4%) patients, respectively. Median (IQR) PSA has significantly dropped to 1.3 (0.6-3.1), 1.4 (0.75-2.9), and 1.7 (0.86-2.75) ng/mL at 6-week, 3-month, and 1-year follow-up, respectively (p < 0.001). IPSS scores post-HoLEP obviously improved with mean (IQR) IPSS of 10 (5-13), 7 (3-12), and 3 (2-5) at 6-week, 3-month, and 1-year, respectively (p < 0.001). Eighty-eight (72%) patients stayed on active surveillance, whereas 27 (23%) patients had radiotherapy ± androgen deprivation therapy for persistently high or relapsing PSA. Within 36 intermediate-risk patients, 15 (41.6%) and patients had radiotherapy, whereas 21 (58.3%) patients continued active surveillance. Conclusions: HoLEP is beneficial in debulking large prostate in PCa patients with bothersome LUTS on active surveillance or before radiotherapy. HoLEP reduces the contribution of large adenoma to PSA level, thus reflecting PSA level better and helping reduce overtreatment.

Abstract
Purpose: Prostate cancer (PCa) and benign prostatic hyperplasia (BPH) are common in elderly men. Data on the laser-based surgery known as thulium vapoenucleation of the prostate (ThuVEP) in PCa patients are rare. Our objective was to analyse the feasibility, safety and functional outcome of ThuVEP in patients with lower urinary tract symptoms (LUTS) and PCa. Methods: Multicentre study, including 1256 men who underwent ThuVEP for LUTS. Maximum urinary flow rate (Qmax) and post-void residual volume (PVR) were measured perioperatively. The International Prostate Symptome Score (IPSS) was measured perioperatively and at follow-up (FU). Perioperative complications were captured. Reoperation rate was captured at FU. Results: Of 994 men with complete data, 286 (28.8%) patients had PCa. The most common Gleason score was 3 + 3 in 142 patients (49.7%). Most common was low-risk PCa (141 pts; 49.3%). PCa patients were older, had smaller prostates and had higher prostate-specific antigen (PSA) values (all p < 0.001). Comparing non-PCa and PCa patients, no differences occurred perioperatively. IPSS, quality of life and PVR decreased (all p < 0.001) and Qmax improved (p < 0.001) in both groups. Reoperation rates did not differ. The results of low- vs. intermediate-/high-risk PCa patients were comparable. Conclusion: ThuVEP is a safe and long-lasting treatment option for patients with LUTS with or without PCa. No differences occurred when comparing low- to intermediate-/high-risk PCa patients.

Abstract
Holmium laser enucleation of the prostate (HoLEP) is a size-independent surgical option for treating benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) with excellent, durable functional outcomes. The prevalence of LUTS secondary to BPH and prostate cancer both increase with age, although the two diseases develop independently. Urologists often face a diagnostic dilemma, as men with LUTS secondary to BPH might also present with an elevated PSA and, therefore, need a diagnostic work-up to exclude prostate cancer. Nevertheless, ~15% of men with a negative elevated PSA work-up will undergo HoLEP and will be diagnosed with incidental prostate cancer at the time of HoLEP. Indeed, prostate cancer is often found in men undergoing HoLEP, and this situation can be challenging to manage. Variables associated with the detection of incidental prostate cancer, strategies to reduce incidental prostate cancer, as well as the natural history and management of this condition have been extensively studied, but further work in this area is still needed.

Abstract
BACKGROUND This study aimed to explore the prevalence and clinical risk factors in patients diagnosed with incidental prostate cancer (IPC) during certain surgeries (transurethral resection of the prostate [TURP], open prostatectomy [OP], and holmium laser enucleation of the prostate [HoLEP]) after clinically suspected benign prostatic hyperplasia (BPH). MATERIALS AND METHODS Literature search of the MEDILINE, Web of Science, Embase, and Cochrane Library databases was performed to identify eligible studies published before June 2021. Multivariate adjusted odds ratios (ORs) and associated 95% confidence intervals (CIs) of the prevalence and clinical risk factors of IPC were calculated using random or fixed-effect models. RESULTS Twenty-three studies were included in the meta-analysis. Amongst the 94.783 patients, IPC was detected in 24.715 (26.1%). Results showed that the chance of IPC detection (10%, 95% CI: 0.07-4.00; P<0.001; I2=97%) in patients treated with TURP is similar to that of patients treated with HoLEP (9%, 95% CI: 0.07-0.11; P<0.001; I2=81.4%). However, the pooled prevalence estimate of patients treated with OP was 11% (95% CI: -0.03-0.25; P=0.113; I2=99.1%) with no statistical significance. We observed increased incidence of IPC diagnosis after BPH surgery amongst patients with higher prostate-specific antigen (PSA) level (OR: 1.13, 95% CI: 1.04-1.23; P=0.004; I2=89%), whereas no effect of age (OR: 1.02, 95% CI: 0.97-1.06; P=0.48; I2=78.8%) and prostate volume (OR: 0.99, 95% CI: 0.96-1.03; P=0.686; I2=80.5%) were observed. CONCLUSIONS The prevalence of IPC was similar amongst patients undergoing TURP, HoLEP, and OP for presumed BPH. Interestingly, increased PSA level was the only independent predictor of increasing risk of IPC after BPH surgery rather than age and prostate volume. Hence, future research should focus on predictors which accurately foretell the progression of prostate cancer to determine the optimal treatment for managing patients with IPC after BPH surgery.

Abstract
Purpose This study investigated functional outcomes in lower urinary tract symptoms (LUTS), the incidence of incidental prostate cancer (PCa), and changes in prostate-specific antigen (PSA) levels after holmium laser enucleation of the prostate (HoLEP) in patients with elevated PSA and benign prostatic hyperplasia (BPH). Methods A retrospective review of a prospectively designed protocol for patients who underwent HoLEP at our institution from January 2010 to May 2020 was conducted. Patients were classified into low-PSA (<3.0 ng/mL) and high-PSA (≥3.0 ng/mL) groups at baseline. Follow-up for PSA was performed at the sixth postoperative month. Baseline and postoperative clinical parameters, functional parameters, PCa incidence, and postoperative changes in PSA were compared between the low- and high-PSA groups. Results The baseline PSA of 1,296 patients (mean age, 69.7±6.8 years) was 4.0±4.1 ng/mL, with 712 patients (55.0%) in the low-PSA group (1.6±0.8 ng/mL), and 584 patients (45.0%) in the high-PSA group (6.9±4.7 ng/mL). Incidental PCa was detected in 82 patients (6.3%), with a similar incidence in the low-PSA (41 patients, 5.9%) and high-PSA (41 patients, 7.0%) groups (P>0.05). At 6 months postoperatively, both groups showed significant improvements in the maximum flow rate, postvoid residual volume, and all domains of the International Prostate Symptom Score (P<0.05). At postoperative 6 months, the PSA level significantly decreased by 66.6%±23.6% in all patients (54.3%±23.9% in the low-PSA group; 79.6%±14.7% in the high-PSA group) (P<0.05), and the PSA levels of 1,264 patients (97.6%) had normalized. Conclusions In patients with elevated PSA presenting with LUTS/BPH, our study demonstrated significant improvements in functional parameters and decreased PSA after HoLEP. The incidental PCa detection rate did not show a statistically significant difference between the low- and high-PSA groups. Timely surgery for LUTS/BPH without delay due to PSA monitoring should be considered.

The significance of the extent of tissue embedding for the detection of incidental prostate carcinoma on transurethral prostate resection material: the more, the better? Virchows Arch 2022; 481:387-396. [PMID: 35710851 PMCID: PMC9485088 DOI: 10.1007/s00428-022-03331-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Revised: 04/19/2022] [Accepted: 04/26/2022] [Indexed: 11/10/2022]
Abstract
The aim of this study is to investigate the incidental prostate cancer (iPCa) detection rates of different embedding methods in a large, contemporary cohort of patients with bladder outlet obstruction (BOO) treated with transurethral surgery. We relied on an institutional tertiary-care database to identify BOO patients who underwent either transurethral loop resection or laser (Holmium:yttrium–aluminium garnet) enucleation of the prostate (HoLEP) between 01/2012 and 12/2019. Embedding methods differed with regard to the extent of the additional prostate tissue submitted following the first ten cassettes of primary embedding (cohort A: one [additional] cassette/10 g residual tissue vs. cohort B: complete embedding of the residual tissue). Detection rates of iPCa among the different embedding methods were compared. Subsequently, subgroup analyses by embedding protocol were repeated in HoLEP-treated patients only. In the overall cohort, the iPCa detection rate was 11% (46/420). In cohort A (n = 299), tissue embedding resulted in a median of 8 cassettes/patient (range 1–38) vs. a median of 15 (range 2–74) in cohort B (n = 121) (p < .001). The iPCa detection rate was 8% (23/299) and 19% (23/121) in cohort A vs. cohort B, respectively (p < .001). Virtual reduction of the number of tissue cassettes to ten cassettes resulted in a iPCa detection rate of 96% in both cohorts, missing one stage T1a/ISUP grade 1 carcinoma. Increasing the number of cassettes by two and eight cassettes, respectively, resulted in a detection rate of 100% in both cohorts without revealing high-grade carcinomas. Subgroup analyses in HoLEP patients confirmed these findings, demonstrated by a 100 vs. 96% iPCa detection rate following examination of the first ten cassettes, missing one case of T1a/ISUP 1. Examination of 8 additional cassettes resulted in a 100% detection rate. The extent of embedding of material obtained from transurethral prostate resection correlates with the iPCa detection rate. However, the submission of 10 cassettes appears to be a reasonable threshold to reduce resource utilization while maintaining secure cancer detection.

Abstract
INTRODUCTION After most surgical management of benign prostatic hyperplasia (BPH), the resected tissue undergoes a histological examination. This examination is performed for the risk of finding an incidental prostate cancer (iPCa). The improvement of prostate cancer detection in the past few years decreased the global iPCa rate. This raises the question of the real benefit for all patients of a systematic histological analysis. The aim of our study was to evaluate the iPCa detection rate on a large contemporary cohort of patients treated for BPH, and to define predictive factors of iPCa detection. PATIENTS AND METHODS We retrospectively analyzed the medical charts of all consecutive patients who underwent surgical treatment for BPH in our academic center from 2012 to 2018. Patients with prostate cancer diagnosed before surgery were not included. All the resected tissue underwent standard histopathological examination. iPCa was defined by any grade or stage of prostate cancer identified on the resected tissue by the histological examination. The following variables were analyzed using an uni- and multi-variable logistic regression as potential risk factors of iPCa: age, total PSA, PSA density (PSAd), prostate volume, technique used, weight of resected tissue and use of 5ARI medication. RESULTS 1045 patients were included in the study. Of them, 439 (42.0%), 206 (19.7%) and 400 (38.3%) underwent HoLEP, OP and TURP, respectively. iPCa was diagnosed in 94 (9.0%) of the 1045. Among them 15 (1.4%) were clinically significant (ISUP score ≥ 2). The multivariable logistic regression analysis identified age (p = 0.03) and PSA density (p < 0.001) as independent predictive factors for the detection of iPCa. Using the median of age and PSAd, we identified a population with 0% of iPCa in our cohort (age < 70 year-old and PSAd < 0.05 ng/mL/mL). CONCLUSION The global iPCa rate was 9% in this contemporary large cohort of patients who underwent surgical treatment for BPH, with 1.4% of clinically significant cancer. Age and PSAd were independent predictive factors to find iPCa. Patients younger than 70 with a PSAd < 0.05 ng/mL/mL had 0% of iPCA in our cohort. In this specific population, we could probably avoid a systematical histological examination of the resected tissue.

Incidental prostate cancer after holmium laser enucleation of the prostate: incidence and predictive factors for clinical progression. Int J Clin Oncol 2022; 27:1077-1083.

Abstract
OBJECTIVES To describe the incidental prostate cancer (iPCa) rate and identify predictive factors for PCa progression after holmium laser enucleation of the prostate (HoLEP). METHODS A retrospective review of all iPCa cases diagnosed after HoLEP procedures between April 2012 and May 2020 was conducted. iPCa was defined as a symptom-free cancer diagnosed after HoLEP in patients without any diagnosis or suspicion of PCa before surgical treatment. PCa progression was suspected by rise in PSA from baseline after HoLEP and confirmed by progressive disease detected on transrectal needle biopsy or by the appearance of metastatic disease. Univariate and multivariate logistic regression were used to identify predictive factors for cancer progression. RESULTS The iPCa rate in our cohort was 10.7% (n = 134). Among patients with iPCa, 25 (18.6%) progressed with a mean follow-up of 32 months. Regarding predictive factors, post-operative PSA (OR 2.35, p < 0.001) was significantly associated with PCa progression in multivariate analysis. The cutoff value for post-operative PSA was determined at 2 ng/mL. Among iPCa cases, 14 patients (10.4%) had both T1b stage disease and PSA ≥ 2 ng/mL, while 68 (50.7%) had neither of these factors. Univariate logistic regression analysis showed that patients with both factors had the highest risk of progression (OR 49.4; p < 0.001). CONCLUSION In this study, post-operative PSA above 2 ng/mL was the only independent risk factor for iPCa progression after HoLEP. Patients with post-operative PSA ≥ 2 ng/mL must be considered to be at risk of progression and may require early curative treatment or closer follow-up in the post-operative period, especially when this is associated with T1b stage disease.

Abstract
Purpose This cohort was to evaluate incidental prostate cancer (iPCa) from men with preoperative benign biopsies and demonstrate their outcomes under different managements. Patients and Methods Between 2015 and 2017, we analyzed the risk factors having iPCa from surgical specimens from men provided with benign preoperative biopsies of their prostates. Furthermore, we compared the survival outcomes according to the different managements after iPCa was diagnosed. Receiver operating characteristic (ROC) curve was utilized to find the best thresholds. Univariable and multivariable nested logit regression were performed to estimate the effect size of different independent variables. Odds ratio (OR) was expressed with 95% confidence interval, and the alpha level was 5%. Results In 295 men we enrolled, there were 57 (19%) men having iPCa from surgical specimens. In univariable logit regression, we found significant variables of age, PSA, prostatic volume, PSA velocity ≥ 0.75 ng/mL/year for 3 years, taking 5α reductase inhibitors, abnormal digital rectal examination, cores of biopsy and surgical methods. In multivariable model, PSA was the strongest variable predicting iPCa (OR 3.81 [2.04–7.07]; Wald: 17.75; p < 0.001). In ROC curve, the best threshold was 9.025 ng/mL (area under curve: 0.95; sensitivity: 0.947; specificity: 0.866). In Kaplan–Meier curve of 27.89-month follow-up, robot-assisted simple prostatectomy (RASP) can provide similar PSA progression-free period as robot-assisted radical prostatectomy (RARP) following transurethral surgeries in organ-confined cancer (Log rank test, p = 0.293), and both of them were better than external-beam radiation therapy (RT) following transurethral surgeries (Log rank test, p < 0.001). Conclusion PSA was the strongest variable to predict iPCa out of prostate with preoperative benign biopsies. RASP was parallel to RARP following transurethral surgeries in organ-confined cancer in the short term.

Abstract
Prostate cancer can be detected incidentally after surgical therapy for benign prostatic obstruction such as holmium laser enucleation of the prostate (HoLEP), thus called incidental prostate cancer (iPCa). We aimed to review the studies on iPCa detected after HoLEP and investigate its prevalence. A detailed search of original articles was conducted via the PubMed-MEDLINE, Web of Science, Wiley Online Library and Cochrane Library databases in the last 10 years up to 1 May 2021 with the following search string solely or in combination: "prostate cancer", "prostate carcinoma", "holmium laser enucleation of the prostate" and "HoLEP". We identified 19 articles to include in our analysis and divided them into six main categories: HoLEP versus open prostatectomy and/or transurethral resection of the prostate in terms of iPCa, oncological and functional outcomes, the role of imaging modalities in detecting iPCa, predictive factors of iPCa, the role of prostate-specific antigen kinetics in detecting iPCa and the management of iPCa after HoLEP. We found that the iPCa after HoLEP rate ranges from 5.64% to 23.3%. Functional and oncological outcomes were reported to be encouraging. Oncological treatment options are available in a wide range.

Holmium laser enucleation versus bipolar resection in the management of large-volume benign prostatic hyperplasia: A randomized controlled trial. Int J Urol 2021; 29:128-135. [PMID: 34788900 DOI: 10.1111/iju.14737] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Revised: 09/28/2021] [Accepted: 10/03/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVES To compare the mid-term safety and efficacy of holmium laser enucleation of the prostate versus bipolar transurethral resection of the prostate in the management of large-volume benign prostatic hyperplasia. METHODS From December 2016 to March 2018, patients with benign prostatic hyperplasia (≥80 cc) were randomized (block randomization, computer-generated random list) to holmium laser enucleation of the prostate (57 patients) or bipolar transurethral resection of the prostate (55 patients). Patients were excluded if they had an International Prostate Symptom Score <13, a maximum urinary flow rate >15 mL/s or presence of prostate cancer, bladder stone, urethral stricture, neurogenic bladder, or previous prostate surgery. The primary outcome was hemoglobin loss. The analysis was intention-to-treat. Postoperative findings (36 months) were compared to baseline characteristics. Univariate and logistic regression analyses were performed for risk factors predicting hemoglobin loss or operative time in all patients. RESULTS There was no significant difference in baseline characteristics between the two groups. Holmium laser enucleation of the prostate was associated with significantly better operative time (P = 0.019), operative efficiency (P < 0.001), hemoglobin loss (P < 0.001), catheterization duration (P < 0.001) and hospital stay (P < 0.001) compared to bipolar transurethral resection of prostate. Both procedures were safe, with no significant difference in total complications (P = 0.128). Blood transfusion (P = 0.026) and capsular perforation (P = 0.239) were reported only in the bipolar transurethral resection of the prostate group. There was no significant difference in rates of urinary tract infections (P = 0.714), urethral strictures (P = 0.359), or transient stress incontinence (P = 0.717). At the last follow-up (3 years), holmium laser enucleation of the prostate was associated with significantly better International Prostate Symptom Scores, prostate-specific antigen levels and maximum urinary flow rates compared to bipolar transurethral resection of the prostate (P < 0.05). In logistic regression analyses, prostate size and bipolar transurethral resection of the prostate were associated with significantly greater hemoglobin loss, whereas prostate size, capsular perforation, and bipolar transurethral resection of the prostate were associated with significantly longer operative time. CONCLUSION Holmium laser enucleation of the prostate and bipolar transurethral resection of the prostate are effective and safe for the management of moderate-to-severe lower urinary tract symptoms attributable to large-volume benign prostatic hyperplasia (≥80 cc). However, if both techniques are available, holmium laser enucleation of the prostate is preferred due its better efficacy and safety profile.

Abstract
Transurethral resection of the prostate is the most commonly performed procedure for the management of patients with lower urinary tract symptoms attributed to benign prostatic hyperplasia (BPH). However, in recent years, various minimally invasive surgical therapies have been introduced to treat BPH. These include laser-based procedures such as holmium laser enucleation of the prostate and photoselective vaporization of the prostate as well as thermal ablation procedures such as water vapor thermal therapy (Rezūm), all of which result in volume reduction of periurethral prostatic tissue. In comparison, a permanent metallic device (UroLift) can be implanted to pull open the prostatic urethra without an associated decrease in prostate size, and selective catheter-directed prostate artery embolization results in a global decrease in prostate size. The goal of this article is to familiarize radiologists with the underlying anatomic changes that occur in BPH as visualized on MRI and to describe the appearance of the prostate on MRI performed after these procedures. Complications encountered on imaging after these procedures are also discussed. Although MRI is not currently used in the routine preprocedural evaluation of BPH, emerging data support a role for MRI in predicting postprocedure outcomes.

Abstract
INTRODUCTION This systematic review aims at reporting the incidence, predictive factors, and the oncological outcomes of incidental prostate cancer (IPCa) in men who underwent endoscopic enucleation of prostate (EEP). METHODS A literature search was performed using the following Medical Subject Heading (MeSH) terms and keywords: "Prostatic Neoplasms", "Prostate Cancer", "Transurethral Resection of Prostate", "Prostate resection", "Prostate enucleation". Meta-analysis was performed if there were two or more studies reporting the same outcome under the same definition. In case of insufficient data, results were presented in a narrative manner. RESULTS Sixty-one studies were included in qualitative synthesis and 55 were included in meta-analysis. The pooled IPCa rate was 0.08 (95% CI 0.073-0.088). Increasing age, higher preoperative serum prostate-specific antigen (PSA) level, higher preoperative PSA density (PSAD), smaller prostate volume, higher postoperative PSA velocity and lower enucleated prostate weight, were reported to have significant correlation with IPCa. In BPH patients, the mean pre-operative and post-operative PSA levels were 5.58 ± 1.48 ng/dL and 1.06 ± 0.27 ng/dL, respectively. In patients with IPCa, the mean pre-operative and post-operative PSA levels were 7.72 ± 2.90 ng/dL and 2.77 ± 1.66 ng/dL, respectively. The mean percentage PSA reduction was 82.0% ± 1.8% for BPH patients and 68.2% ± 12.1% for IPCa patients. IPCa was most commonly managed by active surveillance (68.7%). CONCLUSIONS The pooled incidence of IPCa after EEP was 8%. An absolute post-operative PSA level of < 2.0 and a percentage PSA reduction of > 70% should be expected in BPH patients after EEP.

The significance of a high preoperative PSA level for the detection of incidental prostate cancer in LUTS patients with large prostates. World J Urol 2021; 39:1481-1487.

Abstract
PURPOSE To evaluate the diagnostic value of a high preoperative PSA level for the detection of incidental prostate cancer (iPCa) in LUTS patients with very large prostates (> 100 cc). METHODS We conducted a retrospective analysis of 1125 men treated for LUTS with holmium laser enucleation of the prostate (HoLEP). Patients were stratified according to a preoperative PSA level higher (high PSA; n = 365) or lower than 10 ng/ml (low PSA; n = 760). Preoperative and histopathological parameters were compared between both cohorts. Logistic regression models were used to identify independent predictors of iPCa. RESULTS Demographic parameters were similar between both cohorts. The median PSA levels were 14.2 ng/ml (11.5-19.9) and 4 ng/ml (2.4-6.0). The prostate volume was significantly higher in the high PSA group (105 cc vs. 75 cc; p < 0.001). Correspondingly, the PSA density was significantly increased in the high PSA cohort compared to the low PSA cohort (0.14 vs. 0.05; p < 0.001). The overall detection rate of iPCa showed no difference between groups (9.5% vs. 9.9%). More preoperative prostate biopsies were performed in the high PSA group compared to the low PSA group (46.8% vs. 17.6%; p < 0.001). However, the rate of false negative results was comparable between groups (12.7% vs. 11.1%; p = 0.726). In logistic regression models all PSA-related parameters failed to predict iPCa. CONCLUSIONS PSA-guided approaches to predict iPCa in LUTS patients with very large prostates are not accurate. This finding is useful in clinical practice for counselling our patients and to prevent unwarranted diagnostic procedures.

Abstract
Objective: To investigate the value of standard [digital rectal examination (DRE), PSA] and advanced (mpMRI, prostate biopsy) clinical evaluation for prostate cancer (PCa) detection in contemporary patients with clinical bladder outlet obstruction (BOO) scheduled for Holmium laser enucleation of the prostate (HoLEP). Material and Methods: We retrospectively analyzed 397 patients, who were referred to our tertiary care laser center for HoLEP due to BOO between 11/2017 and 07/2020. Of those, 83 (20.7%) underwent further advanced clinical PCa evaluation with mpMRI and/or prostate biopsy due to elevated PSA and/or lowered PSA ratio and/or suspicious DRE. Logistic regression and binary regression tree models were applied to identify PCa in BOO patients. Results: An mpMRI was conducted in 56 (66%) of 83 patients and revealed PIRADS 4/5 lesions in 14 (25%) patients. Subsequently, a combined systematic randomized and MRI-fusion biopsy was performed in 19 (23%) patients and revealed in PCa detection in four patients (5%). A randomized prostate biopsy was performed in 31 (37%) patients and revealed in PCa detection in three patients (4%). All seven patients (9%) with PCa detection underwent radical prostatectomy with 29% exhibiting non-organ confined disease. Incidental PCa after HoLEP (n = 76) was found in nine patients (12%) with advanced clinical PCa evaluation preoperatively. In univariable logistic regression analyses, PSA, fPSA ratio, and PSA density failed to identify patients with PCa detection. Conversely, patients with a lower International Prostate Symptom Score (IPSS) and PIRADs 4/5 lesion in mpMRI were at higher risk for PCa detection. In multivariable adjusted analyses, PIRADS 4/5 lesions were confirmed as an independent risk factor (OR 9.91, p = 0.04), while IPSS did not reach significance (p = 0.052). Conclusion: In advanced clinical PCa evaluation mpMRI should be considered in patients with elevated total PSA or low fPSA ratio scheduled for BOO treatment with HoLEP. Patients with low IPSS or PIRADS 4/5 lesions in mpMRI are at highest risk for PCa detection. In patients with a history of two or more sets of negative prostate biopsies, advanced clinical PCa evaluation might be omitted.

Management of prostate cancer after holmium laser enucleation of the prostate. Urol Oncol 2020; 39:297.e1-297.e8.

Abstract
INTRODUCTION Holmium laser enucleation of the prostate (HoLEP) is effective in treating lower urinary tract symptoms from prostatic disease. We investigate the role of HoLEP in the management of patients with benign prostatic hypertrophy (BPH) and prostate cancer (CaP). METHODS Retrospective review of data regarding all patients undergoing HoLEP at a single institution was performed. Pre- and postoperative PSA, multiparametric MRI, and pathology results were analyzed for those with CaP identified prior to or incidentally at HoLEP. RESULTS From February 2016 to February 2020, 201 patients underwent HoLEP. Twelve patients had CaP diagnosed before HoLEP: 6 patients with GG1 are on active surveillance (AS), 3 of 4 intermediate-risk patients are on AS and 1 received treatment for disease progression, and both high-risk CaP patients achieved symptomatic benefit from HoLEP and are receiving systemic therapy for CaP. Twenty-one patients (11.1%) with incidentally detected CaP at HoLEP remain on AS or watchful waiting based on clinical scenario. CONCLUSION Screening for CaP in HoLEP candidates with PSA and MRI is recommended given that >10% will have incidental CaP. After HoLEP for BPH/LUTS, patients with CaP can be surveilled with PSA and/or MRI. Further investigation is warranted to determine the durability of success of these approaches.

Abstract
Objectives: To compare the safety and efficacy of holmium laser enucleation of prostate (HoLEP) vs bipolar plasmakinetic resection of prostate (BPRP) in the management of large-sized (≥75 g) benign prostatic hyperplasia (BPH). Methods: This randomized-controlled trial recruited 145 symptomatic BPH patients who had failed medical management, and who had undergone either HoLEP (Versa pulse® 100 W; n = 73) or BPRP (AUTOCON® II 400 ESU; n = 72). Both groups were compared using the Mann-Whitney, chi-square, Student-t, or Fisher exact tests as appropriate. Preoperative vs postoperative findings (24 months) were compared using paired t-test or Wilcoxon signed-rank test. Results: The two groups were comparable for most preoperative findings including prostate size (p = 0.629), although HoLEP included more patients on anticoagulants (p = 0.001). HoLEP was associated with significantly less operative duration (p < 0.001), hemoglobin loss (p < 0.001), catheterization duration (p = 0.009), and hospital stay (p < 0.001). There was no significant difference in total complications (p = 0.291) and each separate complication. Blood transfusion was reported only with BPRP (p = 0.058). At 24 months of follow-up, there was significant improvement in all the parameters in each group (International Prostate Symptom Score [IPSS], maximum urinary flow rate [Qmax], quality of life [QoL], and postvoid residual urine [PVRU]; p < 0.001). There was no significant difference between both groups in postoperative IPSS (p = 0.08), Qmax (p = 0.051), QoL (p = 0.057), or PVRU (p = 0.069). There was significantly better percentage improvement of both IPSS (p = 0.006) and QoL (p = 0.025) in HoLEP. HoLEP and smaller removed (resected or enucleated) tissues were associated with a reduction in the primary outcomes (hemoglobin loss and operative duration) in logistic regression analysis. Conclusion: HoLEP showed better safety profile with significantly less operative duration, hemoglobin loss, hospital stay, and catheterization duration. Although both procedures were effective, HoLEP showed significantly better percentage improvement of both IPSS and QoL. ClinicalTrials.gov Identifier: NCT04143399.

Abstract
PURPOSE To determine the histological validity of the tissue acquired during aquablation of the prostate. PATIENTS AND METHODS Prostatic tissue of 12 patients that consecutively underwent aquablation for benign prostatic enlargement was systematically examined. Histological examination was performed by two experienced uropathologists using a digital slide scanner and slide viewer software (Pannoramic 250 and Case Viewer 2.3, 3D Histech, Hungary). The surface areas of the assessable glands were examined and set in relation to the total surface area of the material available for histology and to the patient's total prostate volume. Examinations were performed analogously in ten consecutive patients undergoing transurethral resection of the prostate (TURP) to facilitate interpretation of the results. Data were analyzed using descriptive statistics. RESULTS A median of 4.06% (range 1.43-7.5%) of the preoperative total prostate volume (median 64.5 ml (range 40-80 ml)) was obtained for histological examination by aquablation. Due to severe mechanical destruction and fragmentation, only a proportion of 0.43% (0.06-1.79%) of this tissue represented histologically assessable glands. Therefore, roughly 0.017% of the total prostatic volume was available for a reliable histological examination. In comparison, 32.5% (6.67-37.5%) of the total prostate volume was removed by TURP and 22.86% (7.45-40.57%) of this tissue represented informative prostatic glands, corresponding to 7.43% of the total prostate volume. CONCLUSION Histological significance of the tissue obtained by aquablation of the prostate is very limited. Costs and effort of the histological examination must, therefore, be weighed critically against the limited informative value.

Urol Int 2020; 104:914-922. [PMID: 32877914 PMCID: PMC7845428 DOI: 10.1159/000510135] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2020] [Accepted: 07/04/2020] [Indexed: 11/19/2022]
Abstract
INTRODUCTION While holmium laser enucleation of the prostate (HoLEP) is accepted as safe and efficient, a long learning curve is considered the main reason for its slow adoption in clinical practice. So far, no standardized and easy-to-use parameter has been implemented to measure surgical experience or efficiency which could be useful for training and quality control purposes. The aim of the present study was to evaluate the learning curves of 2 HoLEP beginners and to identify applicable efficiency outcome measures as well as potentially complicating factors in performing HoLEP. PATIENTS AND METHODS A total of 594 patients treated by HoLEP between September 2016 and May 2019 were enrolled. The procedures were initially performed by 1 HoLEP expert (reference surgeon); over time, 2 further surgeons were trained. Baseline characteristics, enucleation weight, morcellation and enucleation time, laser energy usage, and postoperative results were recorded prospectively. The learning curves of the 2 novices were analyzed and compared to the reference surgeon. Logistic regression analyses were performed to identify predictors for postoperative grade ≥2 complications. RESULTS Median enucleation ratio and complication rates did not significantly alter along the learning curves. Median enucleation speed and laser energy application of the 2 novices significantly improved with growing experience. Combining these variables, we introduced the "HoLEP efficiency score" (HES) which demonstrated the most appropriate value to reflect the surgical experience and efficiency. The median HES for the reference surgeon was 82.8 min kJ/g. For the 2 novices, a drop from 130 and 124.4 min kJ/g by -57 and -30%, respectively, was observed. Among several tested clinical parameters, the presence of prostate cancer (p = 0.047) and the surgical caseload (p < 0.001) influenced the HES. On multivariable logistic regression, American Society of Anesthesiologists score and prostate cancer were independent predictors for grade ≥2 complications (p = 0.002, odds ratio [OR] 2.042 and p = 0.038, OR 1.940). CONCLUSION We introduce the HES as an objective and measurable tool to quantify surgical efficiency. In clinical practice, the HES may find application in training and quality control purposes as well as in comparing surgical modifications and hardware. Patients with prostate cancer seem to be more challenging cases and have a higher risk for complications, and may preferably be treated by experienced surgeons.

Morphologic Factors Associated With Open Conversion During Holmium Laser Enucleation of the Prostate. Urology 2020; 145:258-261. [PMID: 32828870 DOI: 10.1016/j.urology.2020.08.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 08/09/2020] [Accepted: 08/10/2020] [Indexed: 12/12/2022]
Abstract
OBJECTIVE To determine if there is an association between patient body habitus as measured by body mass index (BMI), body surface area (BSA), preoperative prostate volume, postoperative specimen weight, and open conversion with cystotomy or perineal urethrotomy (PU) during holmium laser enucleation of the prostate (HoLEP). We attempt to provide meaningful criteria to assist in preoperative patient counseling. MATERIALS AND METHODS Three hundred consecutive patients underwent HoLEP between August 3, 2018 and February 20, 2020 by a single surgeon. Patient metrics were recorded in a database including age, height, weight, preoperative prostate volume, postoperative specimen weight, catheter dependence, and transfusion requirement. Nine patients were identified who had cystotomy (8) or PU (1) performed during HoLEP secondary to inability to complete the procedure using standard endoscopic technique. Univariate and multivariate statistical analysis was performed. RESULT Younger age, higher BMI, higher BSA, and higher estimated prostate volume were associated with increased risk of open conversion during HoLEP. No patient with a BMI under 30 required open conversion. CONCLUSION Men with BMI >30 kg/m2 or preoperative prostate volume >125 mL should be counseled on the possibility of open conversion with cystotomy or PU. Although the overall risk of conversion is low (3%), the risk may be as high as 10% for patients in the highest quartile of BMI (>30.5 kg/m2) and BSA (>2.2m2).

Abstract
BACKGROUND To compare the diagnostic value of prostate cancer (PCa) between holmium laser enucleation of the prostate (HoLEP) and transurethral resection of the prostate (TURP). METHODS We retrospectively analyzed the clinical data of 2909 patients who underwent surgery for benign prostatic hyperplasia (BPH) from January 2008 to June 2018. A total of 1362 patients received HoLEP, and 1547 patients received TURP. The baseline patient characteristics were collected. We then compared the perioperative outcomes of these patients who diagnosed with incidentally diagnosed prostatic carcinoma (IDPC) or PCa after BPH surgeries. RESULTS The total detection rate of PCa in HoLEP group was higher than that in TURP group (85/6.24% vs. 61/3.94%, p = 0.005). Specifically, 55(4.6%) patients were diagnosed with IDPC in HoLEP group with prostate-specific antigen (PSA) less than 4 ng/ml, and 37(2.7%) patients in TURP group (p = 0.014). For the patients with PSA between 4 and 10 ng/ml, 15(13.9%) patients were diagnosed with PCa after HoLEP, and 6(5.0%) patients after TURP (p = 0.023). But the detection rate of PCa was not significantly different between the two groups when PSA was over 10 ng/ml. On the other hand, 57 in 1215 patients with no prostate biopsy preoperatively were diagnosed with PCa after HoLEP, while 42 in 1370 patients after TURP (4.7% vs. 3.1%, p = 0.040), respectively. Twenty-six patients received once biopsy and diagnosed with PCa in HoLEP group, while 15 patients in TURP group (18.4% vs. 8.9%, p = 0.018), respectively. However, no significant difference was observed for patients who received twice prostate biopsy in the two groups. CONCLUSIONS The present study showed that HoLEP can provide a higher total detection rate of PCa when compared with TURP. Besides, this superiority was especially embodied in patients with PSA less than 10 ng/ml.

Abstract
Introduction: We sought to update our experience of oncologic and functional outcomes of robot-assisted radical prostatectomy (RARP) for prostate cancer in patients with history of holmium laser enucleation of the prostate (HoLEP). Patients and Methods: Twenty-seven patients with previous HoLEP who underwent RARP were matched 1:1 with RARP patients with no history of transurethral surgery. Demographic, operative, oncologic, continence, and erectile function outcomes were analyzed. Results: Median time between HoLEP and RARP was 31 months with a mean prostate-specific antigen doubling time of 4.28 ng/mL/year. Operative times were significantly longer with higher bladder neck reconstruction rates and similarly low complication rates. Biochemical recurrence was relatively low (7%) in the HoLEP group, identical to the comparative group. Continence at last follow-up was not statistically significant between groups, although time to continence favored the non-HoLEP cohort. Erectile function recovery was generally poor in the post-HoLEP cohort (11%), although bilateral nerve sparing was rarely performed (11%). Compared with our initial experience, there were significant improvements in time to continence (16 vs 36 weeks). No T2 post-HoLEP RARP since 2010 has had a positive surgical margin. Conclusions: Post-HoLEP prostatectomy remains feasible with similar perioperative and oncologic outcomes compared with matched cohorts. Functional recovery remains slowed yet may continue to improve with technical familiarity.

Abstract
Background: Holmium laser enucleation of the prostate (HoLEP) has proven to be effective in benign proliferations of the prostate resulting in large prostatic volumes. It is a less-invasive surgical alternative to transurethral resection and surgical resection. Prostatic adenocarcinoma can incidentally be found in the enucleated tissue. Occasionally, nonadenocarcinomatous forms of neoplasia occur such as sarcoma. Case Presentation: Two male patients, both 65 years old, undergo HoLEP for gigantic prostates. The first patient presented with recurrent hematuria and clot retention. After HoLEP, the patient voiding symptoms improved. Pathologic immunostaining of the tissue showed spindle cell proliferation consistent with stromal tumor of uncertain malignant potential (STUMP). The second patient presented with acute urinary retention and subsequently underwent HoLEP. Pathologic examination of the enucleated tissue was consistent with prostatic stromal sarcoma. Conclusion: HoLEP is a well-established surgical treatment for gigantic proliferations of benign prostatic tissue. Occasionally, patients who are candidates for HoLEP may have a rare underlying pathologic condition such as a sarcoma or a STUMP. Exclusion of underlying malignant processes in massive prostates is necessary before operating.

Accuracy of the preoperative PSA level for predicting clinically significant incidental transitional zone-prostate cancer before endoscopic enucleation of very large adenoma. World J Urol 2019; 38:993-1000.

Abstract
OBJECTIVE To analyse the accuracy of high preoperative PSA levels for predicting transitional zone incidental PCa (TZ-PCa) in men with very large prostates. MATERIALS AND METHODS Perioperative data from 375 consecutive patients who underwent endoscopic enucleation of the prostate (EEP) for benign prostatic obstruction between July 2013 and December 2018 were retrospectively reviewed. Patients were stratified into three groups according to the preoperative PSA level: low-PSA (< 4 ng/mL), intermediate-PSA (4 ≤ PSA < 10 ng/mL) and high-PSA (≥ 10 ng/mL). Men in each group were propensity score matched by age, 5α-reductase inhibitor (5-ARI) use, prostate volume and mpMRI. The TZ-PCa incidence rate was retrospectively compared by preoperative PSA level in a propensity score model including all predetermined variables. RESULTS Age, prostate volume, 5-ARI use were similar between patient groups. The median PSA levels in the low-, intermediate- and high-PSA groups were 3 [2.3; 3.4], 6.6 [5.3; 8.1] and 12.7 [11; 16.7] ng/mL, respectively. The median prostate volume was > 100 grams in all groups (108, 105 and 120 cc, respectively). The T1a-Gleason 6 incidental TZ-PCa rate was statistically comparable between the three groups (3.4, 5.1 and 8.6% in the low-, intermediate- and high-PSA groups, respectively). The detection rate of clinically significant TZ-PCa was low for preoperative PSA levels > 4 ng/mL (1.7%); with no difference between the intermediate- and high-PSA groups. CONCLUSION In men with large glands, the clinically significant incidental TZ-PCa detection rate was similar regardless of the preoperative PSA level stratum. Such details may help with patient counselling during BPH surgical management.

Abstract
Transurethral resection of prostate (TURP) still remains the "gold standard" surgical treatment for benign prostatic hyperplasia (BPH). In recent years, holmium laser enucleation of prostate (HoLEP) gets more and more popularity in the world. Our objective is to compare the efficacy and safety of HoLEP and TURP for BPH. Eleven studies met our eligibility criteria including 1339 patients. The prostate sizes of the all included studies were smaller than 100 g. Overall, in patients with small to mid-sized prostates, HoLEP offers safer clinical outcomes with less blood drop and potentially better long-term relief of bladder outlet obstruction.

Does mechanical morcellation of large glands compromise incidental prostate cancer detection on specimen analysis? A pathological comparison with open simple prostatectomy. World J Urol 2018; 37:1315-1320.

Abstract
OBJECTIVE This study sought to compare the incidental prostate cancer (iPCa) detection rate between pathological specimens from green laser enucleation of the prostate (GreenLEP) and open simple prostatectomy (OSP). MATERIALS AND METHODS In two institutions, the charts of all consecutive patients who underwent OSP between January 2005 and December 2010 were retrospectively reviewed, and the data of all consecutive patients who underwent GreenLEP with tissue morcellation between July 2013 and January 2018 were also collected. Preoperative demographics and pathological findings were recorded. iPCa detection rate was retrospectively compared between the GreenLEP and OSP groups in a propensity score model, including all predetermined variables: Age, preoperative PSA level and prostate volume. RESULTS Of 738 patients, 402 were included in the propensity-score matching analysis, and they were equally distributed among groups. The overall iPCa detection rates were similar in both groups (9.9% vs. 8.5%; p = 0.73), and there were no statistically significant differences in terms of tumour stage, Gleason score or the rate of clinically significant iPCa, although the number of cassettes analysed was significantly higher in the morcellation group than in the OSP group. No predictive factors for iPCa were identified. CONCLUSIONS The results of the present study suggest that the mechanical morcellation of large glands had no influence on iPCa detection. Compared with a specimen from standard OSP, a large morcellated tissue sample allows adequate pathological evaluation and does not alter a pathologist's ability to detect iPCa.
