Propensity score-matched evaluation of palliative transurethral resection and holmium laser enucleation of the prostate for bladder outlet obstruction in patients with prostate cancer.

BACKGROUND: While transurethral resection of the prostate (TURP) is the standard-of-care, Holmium laser enucleation of the prostate (HoLEP) is widely accepted as a size-independent method for surgical treatment of patients with lower urinary tract symptoms (LUTS) secondary to bladder outlet obstruction (BOO). However, in an ageing society an increasing number of patients presents with BOO due to locally advanced prostate cancer. There is currently no guidelines recommendation as to the enucleation or resection technique. Therefore, we compared intraoperative performance, postoperative outcomes, and safety for palliative (p)TURP and (p)HoLEP. METHODS: We conducted a retrospective, propensity score-matched analysis of 1373 and 2705 men who underwent TURP or HoLEP for LUTS/BOO between 2014 and 2021, respectively. Patients were matched for age, prostate size and preoperative international prostate symptom score (IPSS). Patients were stratified by technique and groups were compared for perioperative parameters, safety, and functional outcomes. RESULTS: While postoperative symptoms and urodynamic parameters improved irrespective of technique, we report significantly increased resection and enucleation times for palliative indication. For corresponding efficiency parameters, we observed a two-fold higher surgical performance (g/min) for both techniques in patients without prostate cancer. While adverse events were comparable between groups, we found a two-fold higher hemoglobin drop in palliative patients. CONCLUSIONS: Currently, there is no standard-of-care for patients with BOO and locally advanced prostate cancer. Our data show that both TURP and HoLEP offer adequate symptom improvement and comparable safety profiles. While HoLEP is feasible even in larger prostates, both procedures become more difficult in patients with prostate cancer. Taken together, this study covers an important gap in current literature, helping urological surgeons to make evidence-based decisions for the benefit of their patients.

mpMRI-targeted biopsy of the prostate in men ≥ 75 years. 7-year report from a high-volume referral center.

OBJECTIVE: Multiparametric magnetic resonance imaging (mpMRI) -Ultrasound- fusion guided biopsy of the prostate (FBx) is the new gold standard for the detection of prostate cancer. Hallmark studies showing superior detection rates of FBx over randomized biopsies routinely excluded patients≥75 years and information on outcome of FBx on this patient cohort is sparse. As a large referral center, we have performed FBx on a substantial number of patients this age. By evaluating outcome of FBx of patients over the age of 75 years we wanted to close the gap of knowledge on this patient cohort. MATERIALS AND METHODS: Between 2015 -2022, 1577 patients underwent FBx at our department and were considered for analysis. Clinical and histopathological parameters were recorded. Clinical data comprised age at FBx, serum level of Prostate-specific antigen (PSA), prostate volume, PSA-density, history of previous biopsies of the prostate, result of the digital rectal examination (DRE) and assessment of the indexlesion of mpMRI according to the Prostate Imaging and Reporting Data System (PI-RADS). Univariate analysis and multivariable logistic regression was used to identify age barrier of 75 years as a potential risk factor of detection of clinically significant prostate cancer by FBx. RESULTS: 379/1577 patients (24%) were≥75 years and 1198/1577 (76%) patients were < 75 years, respectively. Preoperative PSA was significantly higher in patients≥75 years compared to patients < 75 years (9.54 vs. 7.8, p < 0.001). Patients≥75 years presented significantly more often with mpMRI target lesions classified as PI-RADS 5 compared to patients < 75 years (45% vs. 29%, p < 0.001). Detection rate of clinically significant prostate cancer was significantly higher in patients≥75 years compared to patients < 75 years (63% vs. 43%, p < 0.001). Aggressive prostate cancer grade ISUP 5 was significantly more often detected in patients≥75 years compared to patients < 75 years (13% vs. 8%, p = 0.03). On multivariable logistic regression model adjusted for PSA and PI-RADS score, age barrier of 75 years was identified as a significant risk factor for the detection of clinically significant prostate cancer by FBx (OR: 1.77, 95% CI: 1.36 -2.31, p < 0.001). CONCLUSION: After evaluation of a large patient cohort, we show that age≥75 years represents a significant risk factor for the detection of clinically significant prostate cancer. Further studies on mid- and long term outcome are necessary to draw conclusions for clinical decision making in this patient cohort.

Added value of randomised biopsy to multiparametric magnetic resonance imaging-targeted biopsy of the prostate in a contemporary cohort.

OBJECTIVE: To assess the added value of concurrent systematic randomised ultrasonography-guided biopsy (SBx) to multiparametric magnetic resonance imaging (mpMRI)-targeted biopsy and the additional rate of overdiagnosis of clinically insignificant prostate cancer (ciPCa) by SBx in a large contemporary, real-world cohort. PATIENTS AND METHODS: A total of 1552 patients with positive mpMRI and consecutive mpMRI-targeted biopsy and SBx were enrolled. Added value and the rate of overdiagnosis by SBx was evaluated. PRIMARY OUTCOME: added value of SBx, defined as detection rate of clinically significant PCa (csPCa; International Society of Urological Pathology [ISUP] Grade ≥2) by SBx, while mpMRI-targeted biopsy was negative or showed ciPCa (ISUP Grade 1). SECONDARY OUTCOME: rate of overdiagnosis by SBx, defined as detection of ciPCa in patients with negative mpMRI-targeted biopsy and PSA level of <10 ng/mL. RESULTS: Detection rate of csPCa by mpMRI-targeted biopsy and/or SBx was 753/1552 (49%). Added value of SBx was 145/944 (15%). Rate of overdiagnosis by SBx was 146/656 (22%). Added value of SBx did not change when comparing patients with previous prostate biopsy and biopsy naïve patients. In multivariable analysis, a Prostate Imaging-Reporting and Data System (PI-RADS) 4 index lesion (odds ratio [OR] 3.19, 95% confidence interval [CI] 1.66-6.78; P = 0.001), a PI-RADS 5 index lesion (OR 2.89, 95% CI 1.39-6.46; P = 0.006) and age (OR 1.05, 95% CI 1.03-1.08; P < 0.001) were independently associated with added value of SBx. CONCLUSIONS: In our real-world analysis, we saw a significant impact on added value and added rate of overdiagnosis by SBx. Subgroup analysis showed no significant decrease of added value in any evaluated risk group. Therefore, we do not endorse omitting concurrent SBx to mpMRI-guided biopsy of the prostate.

The Impact of Laser Energy on Functional Outcome Following Holmium Laser Enucleation of the Prostate.

OBJECTIVE: To assess the impact of total laser energy applied, as well as enucleation efficiency on short-term functional outcomes for patients treated for lower urinary tract symptoms (LUTS) with Holmium laser enucleation of the prostate (HoLEP). METHODS: A retrospective analysis of 1593 consecutive patients who underwent HoLEP for LUTS due to benign prostate obstruction in a tertiary care center between January 2018 and January 2021 was performed. Perioperative parameters and short-term functional outcome were evaluated. Spearman's rank correlation and linear regression analysis was applied to identify the relationship between total laser energy applied or enucleation efficiency and functional outcome (P < .05). RESULTS: Median weight of enucleated tissue was 65g, median tissue retrieval percentage was 72.2% and median surgery speed was 0.8g/min. Median laser energy applied was 48.8 kJ, median enucleation efficiency was 1.4g/kJ. No significant correlation between the total laser energy and postoperative International Prostate Symptom Score (IPSS), peak urinary flow (Qmax) or postvoid residual urine volume (PVR) was found (P-range: .473-.969). Likewise, no correlation was found between enucleation efficiency and postoperative IPSS, Qmax, and PVR (P-range: .080-.932). Perioperative improvement of functional outcome (delta IPSS, delta Qmax, and delta PVR) did not correlate with total laser energy applied (P-range: .211-.785) or with enucleation efficiency (P-range: .118-.543). Those results were confirmed in linear regression analysis. CONCLUSION: The results of this study reveal that functional outcome following HoLEP are not dependant on the amount of laser energy applied or enucleation efficiency. Our results should support the increased use of HoLEP as surgical treatment option for LUTS due to BPH.

The Impact of Prostate Volume on the Prostate Imaging and Reporting Data System (PI-RADS) in a Real-World Setting.

Multiparametric magnetic resonance imaging (mpMRI) has emerged as a new cornerstone in the diagnostic pathway of prostate cancer. However, mpMRI is not devoid of factors influencing its detection rate of clinically significant prostate cancer (csPCa). Amongst others, prostate volume has been demonstrated to influence the detection rates of csPCa. Particularly, increasing volume has been linked to a reduced cancer detection rate. However, information about the linkage between PI-RADS, prostate volume and detection rate is relatively sparse. Therefore, the current study aims to assess the association between prostate volume, PI-RADS score and detection rate of csP-Ca, representing daily practice and contemporary mpMRI expertise. Thus, 1039 consecutive patients with 1151 PI-RADS targets, who underwent mpMRI-guided prostate biopsy at our tertiary referral center, were included. Prior mpMRI had been assessed by a plethora of 111 radiology offices, including academic centers and private practices. mpMRI was not secondarily reviewed in house before biopsy. mpMRI-targeted biopsy was performed by a small group of a total of ten urologists, who had performed at least 100 previous biopsies. Using ROC analysis, we defined cut-off values of prostate volume for each PI-RADS score, where the detection rate drops significantly. For PI-RADS 4 lesions, we found a volume > 61.5 ccm significantly reduced the cancer detection rate (OR 0.24; 95% CI 0.16-0.38; p < 0.001). For PI-RADS 5 lesions, we found a volume > 51.5 ccm to significantly reduce the cancer detection rate (OR 0.39; 95% CI 0.25-0.62; p < 0.001). For PI-RADS 3 lesions, none of the evaluated clinical parameters had a significant impact on the detection rate of csPCa. In conclusion, we show that enlarged prostate volume represents a major limitation in the daily practice of mpMRI-targeted biopsy. This study is the first to define exact cut-off values of prostate volume to significantly impair the validity of PI-RADS assessed in a real-world setting. Therefore, the results of mpMRI-targeted biopsy should be interpreted carefully, especially in patients with prostate volumes above our defined thresholds.

[Laser Techniques in the Treatment of Benign Prostatic Syndrome]. / Lasertechniken in der Behandlung des benignen Prostatasyndroms.

Laser Techniques in the Treatment of Benign Prostatic Syndrome Abstract: Lasers have a wide range of applications in endourological therapy. Not only in the treatment of stones, but also in the treatment of benign prostatic syndrome (BPS), their importance continues to grow. The endourological treatment of BPH with different laser techniques will be discussed in more detail in the following. The physical differences between the individual lasers will be explained first, followed by the treatment options that can be performed with a laser. The main focus will be on the concrete comparison of the treatment methods, especially in clinical contexts. In particular, the duration of surgery, length of hospitalisation, risk of post-operative bleeding, catheterisation duration, risk of urinary retention and risk of post-operative complications such as retrograde ejaculation, bladder neck sclerosis, urethra stricture and adenoma recurrence will be listed and compared for the most important methods. Nevertheless, the distribution of TURP to laser is still 30:1 in favour for TURP [1].

[Benign Prostate Hyperplasia - Current Medical Therapy, New Developments, and Side Effects]. / Benigne Prostatahyperplasie.

Benign Prostate Hyperplasia - Current Medical Therapy, New Developments, and Side Effects Abstract: Lower urinary tract symptoms (LUTS) consist of both voiding and storage symptoms. Urethral obstruction leading to voiding symptoms is most commonly attributed to benign prostatic hyperplasia (BPH), where hyperplastic growth and increased smooth muscle tone in the hyperplastic prostate may lead to benign prostate obstruction (BPO). Spontaneous contractions of the detrusor muscle may cause storage symptoms, which are referred to as overactive bladder (OAB). With a considerable proportion of patients suffering from "mixed LUTS", a combination of voiding and storage symptoms, LUTS affect a large portion of the population worldwide, with major impact on quality of life (QoL). A demographic shift in society, will lead to higher incidence and prevalence of LUTS, with a growing economic burden. Standard-of-care medical treatment for LUTS/BPO includes α1-adrenoceptor antagonists and phosphodiesterase-5 (PDE-5) inhibitors, for reduction of prostate smooth muscle tone, and 5α-reductase inhibitors (5-ARI) to slow down disease progression. Medical therapy for LUTS/OAB includes muscarinic receptor antagonists, and ß3-agonists for relief of spontaneous bladder contractions. When left untreated, LUTS may cause considerable adverse events, ranging from acute urinary retention with kidney failure, and recurring infections, to social withdrawal, and depression.

Efficacy, Efficiency, and Safety of En-bloc vs Three-lobe Enucleation of the Prostate: A Propensity Score-matched Analysis.

OBJECTIVE: To assess efficacy, efficiency, and safety in holmium laser enucleation of the prostate (HoLEP), we directly compared intraoperative performance, postoperative outcomes, and safety in the original 3-lobe enucleation technique with the more recent en-bloc method. As HoLEP is widely accepted as a size-independent method for surgical treatment of patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO), detailed understanding of its benefits is mandatory. METHODS: We conducted a retrospective, propensity score-matched analysis of 1,396 men who underwent HoLEP for LUTS/BPO between 2017 and 2020. We included 606 patients in the final analysis (en-bloc n = 303; 3-lobe n = 303), who were matched for prostate size (50 cc), age, body mass index, and preoperative international prostate symptom score. Patients were then stratified by technique, and groups were compared for perioperative parameters, safety, and short-term functional outcomes. RESULTS: While postoperative symptoms and urodynamic parameters improved irrespective of technique, we report significantly less adverse events (Clavien-Dindo classification ≥II vs

Adverse Pathology after Radical Prostatectomy of Patients Eligible for Active Surveillance-A Summary 7 Years after Introducing mpMRI-Guided Biopsy in a Real-World Setting.

OBJECTIVE: Over the last decade, active surveillance (AS) of low-risk prostate cancer has been increasing. The mpMRI fusion-guided biopsy of the prostate (FBx) is considered to be the gold standard in preoperative risk stratification. However, the role of FBx remains unclear in terms of risk stratification of low-risk prostate cancer outside high-volume centers. The aim of this study was to evaluate adverse pathology after radical prostatectomy (RP) in a real-world setting, focusing on patients diagnosed with Gleason score (GS) 6 prostate cancer (PCa) and eligible for AS by FBx. SUBJECTS AND METHODS: Between March 2015 and March 2022, 1297 patients underwent FBx at the Department of Urology, Ludwig-Maximilians-University of Munich, Germany. MpMRI for FBx was performed by 111 different radiology centers. FBx was performed by 14 urologists from our department with different levels of experience. In total, 997/1297 (77%) patients were diagnosed with prostate cancer; 492/997 (49%) of these patients decided to undergo RP in our clinic and were retrospectively included. Univariate and multivariable logistic regression analyses were performed to evaluate clinical and histopathological parameters associated with adverse pathology comparing FBx and RP specimens. To compare FBx and systematic randomized biopsies performed in our clinic before introducing FBx (SBx, n = 2309), we performed a propensity score matching on a 1:1 ratio, adjusting for age, number of positive biopsy cores, and initial PSA (iPSA). RESULTS: A total of 492 patients undergoing FBx or SBx was matched. In total, 55% of patients diagnosed with GS 6 by FBx were upgraded to clinically significant PCa (defined as GS ≥ 7a) after RP, compared to 52% of patients diagnosed by SBx (p = 0.76). A time delay between FBx and RP was identified as the only correlate associated with upgrading. A total of 5.9% of all FBx patients and 6.1% of all SBx patients would have been eligible for AS (p > 0.99) but decided to undergo RP. The positive predictive value of AS eligibility (diagnosis of low-risk PCa after biopsy and after RP) was 17% for FBx and 6.7% for SBx (p = 0.39). CONCLUSIONS: In this study, we show, in a real-world setting, that introducing FBx did not lead to significant change in ratio of adverse pathology for low-risk PCa patients after RP compared to SBx.

How does symptom severity impact clinical outcomes of men with lower urinary tract symptoms after holmium laser enucleation or transurethral resection of the prostate?

Introduction: International Prostate Symptom Score (IPSS) is a validated outcome measure for the evaluation of patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO). When treating patients with transurethral resection of the prostate (TURP) or holmium laser enucleation of the prostate (HoLEP), patient selection is key to achieve the best clinical outcome. Therefore, we analyzed how the severity of LUTS as determined by IPSS influenced postoperative functional outcomes. Material and methods: We conducted a retrospective, matched-pair analysis of 2,011 men who underwent HoLEP or TURP for LUTS/BPO between 2013-2017. We included 195 patients in the final analysis (HoLEP n = 97; TURP n = 98), who were matched for prostate size (50 cc), age, and body mass index. Patients were then stratified by IPSS. Groups were compared for perioperative parameters, safety and short-term functional outcomes. Results: While preoperative symptom severity was a significant predictor of postoperative clinical improvement, patients who received HoLEP showed superior postoperative functional results with higher peak flow rates and 2-fold greater improvement in IPSS. In patients presenting with severe symptoms, we observed 3- to 4-fold less Clavien-Dindo grade ≥II and overall complications after receiving HoLEP compared to TURP. Conclusions: Patients with severe LUTS were more likely to experience clinically significant improvement after surgery than patients with moderate LUTS, and HoLEP showed superior functional outcomes than TURP. However, patients with moderate LUTS should not be denied surgery, but may warrant a more comprehensive clinical work-up.

Holmium laser enucleation of the prostate: A truly size-independent method?

OBJECTIVES: To evaluate the impact of prostate size on functional outcomes and perioperative morbidity, we analyzed patients undergoing holmium laser enucleation of the prostate (HoLEP) for lower urinary tract symptoms (LUTS). As LUTS secondary to benign prostatic obstruction (BPO) are a chronic progressive disease, prevalence and prostate size increase with age. HoLEP is a size-independent method for surgical treatment of LUTS/BPO and can be offered in medication-refractory patients with durable long-term results and reduced perioperative morbidity. METHODS: We retrospectively collected data of 852 patients who underwent HoLEP for LUTS secondary to BPO between 2014-2018. Patients were divided into group 1 (≤60 cc), group 2 (>60 < 120 cc), group 3 (≥120 cc). Perioperative parameters, safety and short-term functional outcomes were assessed and analyzed. RESULTS: Patients in group 3 were significantly older and showed a significantly higher median prostate-specific antigen level. Perioperative parameters, such as enucleation time and morcellation time significantly differed in favor of smaller prostate sizes, while enucleation and morcellation speed showed favorable results for larger prostate sizes. Larger prostates ≥120 cc showed a significantly higher postoperative drop in hemoglobin. However, patients did not differ in postoperative functional outcomes or Clavien-Dindo grade ≥II complications (4.8% of all patients [41/852]). There was no difference in perioperative complications between all groups (P = 0.760). CONCLUSION: While larger prostates take significantly longer to operate on, postoperative functional outcomes show no difference between all sizes. In conclusion, HoLEP is a size-independent and effective method for surgical treatment of LUTS/BPO in prostates ≥30 cc.

Spinal Versus General Anesthesia for Holmium Laser Enucleation of the Prostate of High-risk Patients - A Propensity-score-matched-analysis.

OBJECTIVE: To compare perioperative management and functional outcome of spinal anesthesia (SpA) to general anesthesia (GA) in high-risk patients treated for lower urinary tract symptoms with Holmium laser enucleation of the prostate (HoLEP). METHODS: In the current retrospective analysis, a propensity-score-matching of patients treated for lower urinary tract symptom with HoLEP (n = 300) in SpA with ASA>2 (n = 100), GA with ASA>2 (GA-high-risk) (n = 100) or GA with ASA≤2 (GA-low-risk) (n = 100) was performed. The impact of anesthesiologic mode on perioperative anesthesiologic outcome, early functional outcome and treatment related adverse events (according to Clavien Dindo), was evaluated. RESULTS: Hypotensive episodes were significantly less frequent in the SpA-cohort (9%) compared to the GA-high-risk cohort (32%) and the GA low-risk cohort (22%) (each P <.05 respectively). SpA-patients showed a significantly shorter median time in post anesthesia care unit (PACU-time: 135 minutes; 120-166.5) compared to GA-high-risk patients (186 minutes; 154-189.5), with significant less referrals to Intermediate care unit (1% vs 9 %); (each P <.05). PACU-time (99 minutes) and Intermediate care unit referrals (0%) for GA-low-risk were lower than for both other cohorts. Postoperative requirement for analgesics was significantly lower in the SpA-cohort (2%), compared to both GA-cohorts (74% and 61% respectively; P <.05). No significant difference was found regarding early functional outcome or treatment related adverse events (p-range: 0.201-1.000). CONCLUSION: For patients undergoing HoLEP, SpA provides greater hemodynamic stability and allows faster overall postoperative recovery with preferable pain management. Yielding a comparable functional outcome, it is a safe and efficient alternative to GA in high-risk patients.

The impact of preoperative lower urinary tract symptoms medication on the functional performance of holmium laser enucleation of the prostate.

INTRODUCTION: Medical treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO) targets prostate size, to prevent disease progression, and prostate smooth muscle tone for rapid relieve of LUTS. Holmium laser enucleation of the prostate (HoLEP) is a size-independent method for surgical treatment of LUTS/BPO in medication-refractory patients and offers durable long-term results with reduced perioperative morbidity. As up to 50% of patients receive medical treatment for LUTS/BPO prior to surgery, we analyzed the impact of alpha-blockers and 5-alpha reductase inhibitors (5-ARI) on outcomes and perioperative morbidity in patients undergoing HoLEP for LUTS. MATERIAL AND METHODS: We retrospectively gathered data of 1,057 patients, who underwent HoLEP for LUTS/BPO from 2013-2018, and divided patients into group 1 (no medication), group 2 (α-blockers), and group 3 (5-ARI and α-blockers). Perioperative parameters, short-term functional outcomes and safety were assessed and statistical analysis was performed using SPSS V26.0 software. RESULTS: Even though preoperative LUTS profile was significantly different between groups, all patients improved significantly after HoLEP, irrespective of preoperative LUTS medication. Median improvement of IPSS was 9, 8 and 7 points, of Qmax was 10, 12 and 9.5 ml/s, with significant improvement of quality of life (QoL) and reduction of post-void residual volume (PVR) for groups 1-3, respectively, 30 days after surgery. With only 4.0% (42/1,057) of patients experiencing a Clavien-Dindo grade ≥II complication, there was no difference in prevalence of perioperative complications between groups (p = 0.943). CONCLUSIONS: Although preoperative LUTS medication does not impair efficacy of HoLEP with acceptable perioperative morbidity, the time gap between medical therapy and surgical treatment may favor an earlier response.

[The role of the microbiome in urological diseases]. / Die Rolle des Mikrobioms bei urologischen Erkrankungen.

The use of modern molecular technologies in the last decade has given us new insights into the complex interactions of the human microbiome in health and in the pathogenesis of diseases. Among other things, the sterility concept of the urinary tract has been discarded and the goal is now to identify the different microbial signatures associated with various diseases. Dysbalances of the microbiome are increasingly suspected of causing negative effects on various malignant and benign diseases. Recently, such associations have also been shown for prostate carcinoma, renal cell carcinoma and urinary bladder carcinoma. This may lead to the discovery of new potential biomarkers for the diagnosis and as a therapeutic target of the diseases mentioned. For the diagnosis of some benign diseases such as interstitial cystitis, urge incontinence and chronic prostatitis or chronic pelvic pain syndrome, microbial involvement was previously considered an exclusion criterion. However, current studies show that the individual patient's microbiome can have an influence on the development and severity of the respective disease.

Enucleation vs. Resection: A Matched-pair Analysis of TURP, HoLEP and Bipolar TUEP in Medium-sized Prostates.

OBJECTIVE: To evaluate efficacy and safety of holmium laser enucleation of the prostate (HoLEP), bipolar enucleation of the prostate (bTUEP) and transurethral resection of the prostate (TURP) in medium-sized prostates (50cc). METHODS: We present a retrospective analysis of 2230 patients treated for lower urinary tract symptoms. We analysed perioperative parameters, short-term clinical outcomes and adverse events in matched-pair cohorts. RESULTS: Both HoLEP and bTUEP were superior in terms of efficacy compared to TURP (surgery time: 51min and 50min vs. 60min; P < 0.001; tissue retrieval percentage: 71.4% and 70% vs. 50%; P < 0.001) and showed stronger improvement of LUTS (change IPSS: -15 and -14 vs. -10; P = 0.008). Furthermore, urodynamic parameters (Qmax: +15 ml/s and +19 ml/s vs. +12 ml/s; P < 0.001; PVR: -100 ml and -95 ml vs. - 80ml; P < 0.008) were significantly more improved after enucleation than after TURP. All techniques showed an equally low complication rate (6.9% and 6.9% vs. 10.3%; P = 0.743). No relevant difference of clinical outcomes was identified between HoLEP and bTUEP. CONCLUSION: Both resection and enucleation are efficient and safe procedures in patients with medium-sized prostates (50cc), but irrespective of the technical approach, transurethral enucleation is superior to TURP in terms of perioperative and functional outcomes.

The clinical value of holmium laser enucleation of the prostate in octogenarians.

OBJECTIVES: With holmium laser enucleation of the prostate (HoLEP) a size-independent method for surgical treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO) has been introduced. HoLEP offers durable long-term results with reduced perioperative morbidity. As the risk of disease progression increases with age, the main goals, when offering surgery to an elderly population, are reducing perioperative morbidity and preserving quality of life (QoL). We therefore analyzed the impact of age on outcomes and perioperative morbidity in patients undergoing HoLEP for LUTS at our tertiary referral center. METHODS: We retrospectively collected data of 487 patients who underwent HoLEP for LUTS secondary to BPO between 2018 and 2019. Patients were divided into group 1 (<70 years), group 2 (70-79 years), and group 3 (≥80 years). Perioperative parameters, safety, and short-term functional outcomes were assessed and analyzed. RESULTS: Perioperative Clavien-Dindo grade ≥II complications were seen in 4.1% of patients (20/487). There was no difference in perioperative complications between all age groups (P = .176). Functional outcome was assessed 30 days post surgery. There was significant improvement in median International Prostate Symptom Score of 14, 10, and 8 points for groups 1, 2, and 3 (P < .001), respectively, with constant improvement of median QoL of 3 points for all groups. Median maximum flow rate (Qmax ) showed significant improvement of 14.5, 10.5, and 13 mL/s for groups 1 to 3 (P = .467), respectively. CONCLUSION: HoLEP offers acceptable perioperative complication rates even in the oldest patient cohort (≥80 years). Therefore, HoLEP is a safe and efficient option even in oldest patients.
