Minimally invasive surgical therapies for benign prostatic hyperplasia in the geriatric population: A systematic review.

BACKGROUND: Geriatric patients, prone to adverse events (AEs) and low compliance with drugs, may benefit from minimally invasive surgical therapies (MISTs) for managing benign prostatic hyperplasia (BPH). We evaluated the efficacy, safety, and procedural characteristics of MISTs in geriatric patients with BPH. METHODS: PubMed/MEDLINE database was systematically searched for relevant articles through October 1, 2023. Eligible studies focused on geriatric patients (≥65 years) with BPH who were treated with MISTs and evaluated follow-up surgical, micturition, and/or sexual outcomes. Studies were included if there was separate reporting for age subgroups ≥65 years, or if the mean age minus standard deviation was ≥65 years, or if the first quartile was ≥65 years. RESULTS: Out of 292 screened studies, 32 (N = 3972 patients) met inclusion criteria and assessed prostatic artery embolization (PAE), Rezum, GreenLight, holmium laser enucleation of the prostate (HoLEP), thulium laser enucleation of the prostate (ThuLEP), diode laser enucleation of the prostate (DiLEP), and Aquablation. Except for Rezum, all MISTs required a planned overnight stay. While PAE and Rezum could be performed under local anesthesia, the other MISTs needed general or spinal anesthesia. Postoperative catheterization duration was longest for PAE (median 14 days) and Rezum (21 days) and shortest for GreenLight (1.9 days). At 12 months postoperatively, all MISTs exhibited significant percent changes in International Prostate Symptom Score (median -69.9%) and quality of life (median -72.5%). Clavien-Dindo Grade 1 AEs ranged widely, with PAE (5.8%-36.8%), Rezum (0%-62.1%), and GreenLight (0%-67.6%) having the largest range, and HoLEP (0%-9.5%), ThuLEP (2%-6.9%), and DiLEP (5%-17.5%) having the smallest. PAE, Rezum, DiLEP, and Aquablation reported no significant changes in the International Index of Erectile Function. CONCLUSIONS: Although all the MISTs reviewed in this study effectively treat BPH in geriatric patients, differences in procedural characteristics and safety profiles across MISTs were considerable. Physicians should use shared decision-making processes, considering risks and patient characteristics, when choosing a suitable treatment option for their patients.

Does larger prostate size provide protection for cancer specific outcomes in localized prostate cancer.

OBJECTIVE: Benign prostatic hyperplasia is common in the aging population and frequently comorbid with localized prostate cancer. Large prostate volume places significant challenges in robotic prostatectomy including reduced mobility and visualization. The goal of this study is to evaluate the effect of prostate volume as a continuous variable on cancer specific outcomes. METHODS: Three thousand four hundred and twenty five patients with localized prostate cancer at a single institution who underwent robotic prostatectomy were retrospectively reviewed. A number of preoperative, operative, and postoperative variables were collected to evaluate cancer specific outcomes including pathologic stage, tissue margins, and biochemical recurrence (BCR). Logistic regression models and univariate and multivariate analyses were implemented for pathologic stage T3 and BCR respectively. RESULTS: The median follow up time was 52 months (IQR 18-95). 37.4% of the patients had a final pathologic stage of T3 or higher, 21.2% experienced positive surgical margins, and 24.7% of patients experienced BCR. Prostate size was a significant predictor of all three outcomes of interest. Increasing prostate size was protective against both higher pathologic stage and positive surgical margins (odds ratio = 0.989, 0.990 respectively, p < 0.001). There was a modest increase in the risk of BCR with increasing gland size (hazard ratio = 1.006, p < 0.001). These results were most significant for patients with Gleason Grade Groups 1 and 2 prostate cancer. CONCLUSION: Prostate size is a commonly determined clinical factor that effects both surgical planning and cancer specific outcomes. Increasing prostate size may offer protection against higher stage disease and positive surgical margins. While surgically challenging, favorable oncologic outcomes can be consistently achieved for patients with low-intermediate risk disease.

Ejaculatory and erectile function outcomes following holmium laser enucleation of the prostate.

PURPOSE: Holmium laser enucleation of the prostate (HoLEP) is a surgical treatment option for benign prostatic hyperplasia (BPH). Many men develop retrograde ejaculation postprocedure, but there is conflicting evidence regarding sexual function outcomes post-HoLEP. We sought to examine significant variations in patient-reported erectile and ejaculatory function within 12 months post-HoLEP. MATERIALS AND METHODS: We conducted a retrospective study for patients who underwent HoLEP between Nov 2018 and Feb 2022. Of the reviewed patients, 277 patients met inclusion criteria and completed pre and postoperative questionnaires, which included the Male Sexual Health Questionnaire- Ejaculatory Dysfunction (MSHQ-EJD) and the International Index of Erectile Function/Sexual Health Inventory for Men (IIEF-5/SHIM). Surveys were provided to patients up to 12 months postprocedure. Demographics and comorbidities associated with sexual dysfunction were collected. Responses to each question were analyzed to detect sub-categorical variations in sexual function as the secondary objective. Data was analyzed by using a linear mixed model. RESULTS: There was a significant decline in total scores for the MSHQ-EJD (8.70 pre-HoLEP vs. 6.58 post HoLEP, p ≤ 0.001) including a significant decline (p < 0.005) in questions 1-3 which assess ejaculatory ability, strength, and volume. There was not a significant decline in question 4 which assesses bother (2.552 pre-HoLEP vs. 3.119 post-HoLEP, p = 0.526). There was not a significant decline in the IIEF-5/SHIM postoperatively (11.51 pre-HoLEP vs. 13.327 post-HoLEP, p = 0.498). CONCLUSIONS: Patients undergoing HoLEP do not experience a decline in erectile function. Patients do experience a decline in ejaculatory function but did not find this bothersome.

Management of Lower Urinary Tract Symptoms Attributed to Benign Prostatic Hyperplasia (BPH): AUA Guideline Amendment 2023.

PURPOSE: The purpose of this American Urological Association (AUA) Guideline amendment is to provide a useful reference on the effective evidence-based management of male lower urinary tract symptoms secondary/attributed to BPH (LUTS/BPH). MATERIALS AND METHODS: The Minnesota Evidence Review Team searched Ovid MEDLINE, the Cochrane Library, and the Agency for Healthcare Research and Quality (AHRQ) database to identify studies relevant to the management of BPH. The guideline was updated in 2023 to capture eligible literature published between September 2020 and October 2022. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions. RESULTS: The BPH amendment resulted in changes to statements/supporting text on combination therapy, photoselective vaporization of the prostate (PVP), water vapor thermal therapy (WVTT), laser enucleation, and prostate artery embolization (PAE). A new statement on temporary implanted prostatic devices (TIPD) was added. In addition, statements on transurethral needle ablation (TUNA) and transurethral microwave thermotherapy (TUMT) were removed and information regarding these legacy technologies was added to the background section. References and the accompanying treatment algorithms were updated to align with the updated text. CONCLUSION: This guideline seeks to improve clinicians' ability to evaluate and treat patients with BPH/LUTS based on currently available evidence. Future studies will be essential to further support these statements to improve patient care.

Systematic review and network meta-analysis of re-intervention rates of new surgical interventions for benign prostatic hyperplasia.

OBJECTIVE: To assess the re-intervention rates of new surgical benign prostatic hyperplasia (BPH) interventions, as the clinical durability of new surgical interventions for BPH is not widely known. METHODS: A critical review of new surgical BPH therapies namely 'UroLift®', 'Aquablation', 'Rezum', 'prostatic artery embolisation (PAE)' and 'temporary implantable nitinol device (iTIND)' was performed on PubMed, the Cochrane Library, and Embase databases between May 2010 and December 2022 according to the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) statement. All relevant articles were reviewed, and the risk of bias was evaluated using the Cochrane risk assessment tool and Newcastle-Ottawa Scale. RESULTS: Of the 32 studies included, there were 10 randomised controlled trials and 22 prospective observational cohorts. A total of 2400 participants were studied with a median patient age of 66 years, a median prostate volume of 51.9 mL, and a median International Prostate Symptom Score of 22. The lowest re-intervention rate at 12 months was for Aquablation at 0.01%, followed by Rezum at 0.02%, iTIND at 0.03%, and PAE at 0.05%. Network meta-analysis (NMA) showed that the best-ranked treatment at 12 months was transurethral resection of the prostate (TURP), followed by Aquablation, iTIND, Rezum, and UroLift. Re-intervention rates with these new BPH interventions are comparable, although some interventions reported better outcomes than TURP in the shorter term. CONCLUSIONS: While this systematic review and NMA showed that the re-intervention rate with these new surgical BPH interventions appears to be comparable to TURP in the short term, further studies are required to directly compare these various BPH procedures.

Trends in day-case bladder outflow obstruction surgery: a study using Hospital Episode Statistics.

OBJECTIVES: To describe the contemporary evolution of day-case bladder outflow obstruction (BOO) surgery in England and to profile day-case BOO surgery practices across England in terms of the types of operation performed and their safety profiles. MATERIALS AND METHODS: This was a retrospective observational analysis of Hospital Episode Statistics and UK Office for National Statistics data. All 111 043 recorded operations across 117 hospital trusts over 66 months, from 1 January 2017 to 30 June 2022, were obtained. Operations were identified as one of: transurethral resection of prostate (TURP); laser ablation or enucleation; vapour therapy; prostatic urethral lift (PUL); or bladder neck incision. Monthly day-case rate trends were plotted across the study period. Descriptive data, day-case rates and 30-day hospital readmissions were analysed for each operation type. Multilevel regression modelling with mixed effects was performed to determine whether day-case surgery was associated with higher 30-day hospital readmissions. RESULTS: Day-case patients were younger, with fewer comorbidities. Time series analysis showed a linear day-case rate increase from 8.3% (January 2017) to 21.0% (June 2022). Day-case rates improved for 92/117 trusts in 2021/2022 compared with 2017. Three of the six trusts with the highest day-case rates performed predominantly day-case TURP, and the other three laser surgery. Nationally, PUL and vapour surgery had the highest day-case rates (80.9% and 38.1%). Most inpatient operations were TURP. Multilevel regression modelling found reduced odds of 30-day readmission after day-case BOO surgery (all operations pooled), no difference for day-case vs inpatient TURP, and reduced odds following day-case LASER operations. CONCLUSIONS: The day-case rates for BOO surgery have linearly increased. Minimally invasive surgical technologies are commonly performed as day cases, whereas high day-case rates for TURP and for laser ablation operations are seen in a minority of hospitals. Day-case pathways to treat BOO can be safely developed irrespective of operative modality.

Prospective study of urinary incontinence recovery following endoscopic enucleation of the prostate.

OBJECTIVE: To investigate the clinical trajectories and identify risk factors linked to post-enucleation urinary incontinence (UI). PATIENTS AND METHODS: In this prospective study (April 2020 to March 2022) at a single institution, 316 consecutive patients receiving endoscopic enucleation due to benign prostatic enlargement were included. Patient information and perioperative details were collected. Follow-ups, from 1 to 6 months, assessed postoperative UI using International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form and a four-item pad questionnaire, classified per International Continence Society definitions. Logistic regression analysed predictors at 1 week, while generalised estimating equation assessed risk factors from 1 to 3 months postoperatively. RESULTS: Patients with a median prostate volume of 57 mL underwent enucleation, with 22.5% experiencing postoperative UI at 1 week, 5.6% at 3 months, decreasing to 1.9% at 6 months. Multivariable analysis identified age (>80 years), specimen weight (>70 g), en bloc with anteroposterior dissection, and anal tone (Digital Rectal Examination Scoring System score <3) as potential factors influencing UI. Subgroup analysis revealed that specimen weight was associated with both continuous and stress UI. Anal tone was related to both other types and stress UI, while overactive bladder symptoms were associated with urge UI. CONCLUSION: In summary, our study elucidates transient risk factors contributing to temporary post-enucleation UI after prostatectomy. Informed decisions and personalised interventions can effectively alleviate concerns regarding postoperative UI.

Effect of detrusor underactivity on surgical outcomes of holmium laser enucleation of the prostate.

OBJECTIVE: To evaluate the effect of detrusor underactivity (DUA) on the postoperative outcomes of holmium laser enucleation of the prostate (HoLEP) in patients with benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: Patients with BPH who underwent HoLEP between January 2018 and December 2022 were enrolled in this prospective database study. Patients were divided into DUA (bladder contractility index [BCI] <100) and non-DUA (BCI ≥100) groups. Objective (maximum urinary flow rate [Qmax], post-void residual urine volume [PVR]) and subjective outcomes (International Prostate Symptom Score [IPSS], Overactive Bladder Symptom Score [OABSS], satisfaction with treatment question [STQ], overall response assessment [ORA], and willingness to undergo surgery question [WUSQ]) were compared between the two groups before surgery, and at 3 and 6 months after HoLEP. RESULTS: A total of 689 patients, with a mean (standard deviation [SD]) age of 69.8 (7.1) years, were enrolled. The mean (SD) BCI in the non-DUA (325 [47.2%]) and DUA (364 [52.8%]) groups was 123.4 (21.4) and 78.6 (14.2), respectively. Both objective (Qmax and PVR) and subjective (IPSS, IPSS-quality of life, and OABSS) outcomes after surgery significantly improved in both groups. The Qmax was lower in the DUA than in the non-DUA group postoperatively. At 6 months postoperatively, the total IPSS was higher in the DUA than in the non-DUA group. There were no significant differences in surgical complications between the two groups. Responses to the STQ, ORA, and WUSQ at 6 months postoperatively demonstrated that the patients were satisfied with the surgery (90.5% in the DUA group; 95.2% in the non-DUA group), their symptoms improved with surgery (95.9% in the DUA group; 100.0% in the non-DUA group), and they were willing to undergo surgery again (95.9% in the DUA group; 97.9% in the non-DUA group). There were no significant differences in the responses to the STQ and WUSQ between the two groups. CONCLUSION: Our midterm results demonstrated that patients with BPH and DUA showed minimal differences in clinical outcomes after HoLEP compared to those without DUA. The overall satisfaction was high in the DUA group.

The early learning curve of the bipolar enucleation of the prostate: a multicenter cohort study.

OBJECTIVES: To evaluate the early learning curve of BipolEP (Bipolar Enucleation of the Prostate). SUBJECTS/PATIENTS AND METHODS: We conducted a retrospective, multicenter analysis of surgical and functional outcomes of patients treated with BipolEp for BPO (benign prostatic obstruction). We evaluated the first 20 cases of BipolEp performed by four different surgeons in three different countries. The following baseline parameters were obtained: age, IPSS, indwelling catheter, transrectal measured prostate volume, post void residual volume (PVR) and uroflowmetry. The learning curve was analysed based on perioperative parameters and the influence of perioperative parameters was correlated with the sequence of BipolEp cases. RESULTS: 84 BipolEp operations performed by 4 different surgeons in their early learning curve were studied. Mean prostate volume was 75 ml, 39% of cases had an indwelling catheter and the average operating time was 101 min. Three out of four surgeons performed at least 50% of successful operations according to Trifecta (complete enucleation and morcellation < 90 min., no conversion to TUR-P). Conversion rate to TURP was 11.9% in total which however was driven by a single surgeon with an almost 50% conversion rate. Mean enucleated prostate was 33.3 gr (18-54.5). Intraoperative complications and reported stress incontinence ranged from 0 to 38.1%. At six-weeks review, the IPPS improved by 12.5 (8-16) points and Qmax by 208% (109.8-266.7). Uroflowmetry outcomes correlated with the sequence of cases with a linear improvement during 20 consecutive cases (p = 0.018) in all centres. Major complications (Clavien Dindo ≥ 3) were rare (4.8%) and comparable between the groups. CONCLUSION: Surgeons starting to learn BipolEp can expect to be able to achieve a linear improvement in Uroflow at the six-week postoperative evaluation after 20 consecutive cases. BipolEp can be successfully performed during the early learning curve with an acceptable rate of conversion to standard TUR-P.

Optimizing hemostasis in HoLEP surgery: retrospective review of selective bipolar plasmakinetic technology guided by bladder irrigation fluid color.

OBJECT: To evaluate the effectiveness of selective bipolar plasmakinetic technology based on bladder irrigation fluid color on hemostasis in HoLEP surgwery METHODS: A total of 209 patients who underwent HoLEP surgery from October 2021 to July 2023 were included and divided into Hemostasis Management Group and control group. the color of the irrigation fluid was categorized into 5 levels and the bipolar plasmakinetic technology was applied when the color came to level 4 or up. The following was analyzed: postoperative use of balloon compression, blood loss, irrigation time, length of hospital stay, and the number of a second operation. RESULTS: Only 4 patients in Hemostasis Management Group required postoperative urinary catheter balloon compression, while there are 15 in the control group(p=0.03). The average irrigation time for patients in the HM Group with bipolar plasmakinetic hemostasis was 21.88±13.76 hours, compared to that in patients with catheter balloon compression(p=0.007). CONCLUSION: Based on the bladder irrigation color chart, the selective application of bipolar plasmakinetic hemostasis led to a significant reduction in the number of patients requiring postoperative bladder catheter balloon compression. Secondly, the irrigation time of patients who underwent bipolar plasmakinetic hemostasis also decreased.

Predicting the risk of failed trial without catheter following Rezum™ therapy.

PURPOSE: Convective water vapor thermal therapy or "Rezum™" treatment for lower urinary tract symptoms in men with benign prostate hypertrophy require postoperative catheterization to avoid acute urinary retention. Unsuccessful catheter removal is still unpredictable. We, therefore, aimed to identify the risk factors of failed initial trial without catheter (TWOC) after Rezum™ therapy inside a large cohort of patients. METHODS: A retrospective study was conducted on patients who underwent Rezum™ therapy by three referent urologists across two academic hospitals between January 2022 and January 2023. A Foley catheter was systematically placed after therapy for 7 days in all patients before TWOC. Patients characteristics [age, imagery, maximum urinary flow rate (Qmax), postvoid residual (PVR)], and treatment outcomes (International Prostate Symptom Score (IPSS), quality of life (QoL), adverse events) were analyzed at baseline and 3 months from procedure. Failed initial TWOC was defined as the incapacity to pass urine or measured PVR > 300 mL. After univariate selection, the risk factors for TWOC failure were identified using multivariate logistic regression analysis. RESULTS: 216 patients qualified for analysis with 23 (10.6%) failing the first TWOC after 7 days of catheterization. After multivariate logistic regression, only preoperative PVR predicted TWOC failure (OR 1.01; p = 0.007). The cut-off of preoperative PVR increasing this risk was 120 mL (p = 0, 02). CONCLUSION: Over 10% of men undergoing Rezum™ therapy for LUTS/BPH will experience TWOC failure and AUR after 7 days of catheterization. Preoperative PVR seems to be the only independent risk factor of unsuccessful catheter removal.

Bladder neck contracture following transurethral surgery of prostate: a retrospective single-center study.

PURPOSE: Bladder neck contracture (BNC) is a rare but intolerant complication after transurethral surgery of prostate. The present study aims to investigate the incidence and risk factors of BNC in patients diagnosed benign prostate hyperplasia (BPH) and following transurethral resection or enucleation of the prostate (TURP/TUEP). METHODS: This retrospective study included 1008 BPH individuals who underwent transurethral surgery of the prostate between January 2017 and January 2022. Patients' demographics, medical comorbidities, urologic characteristics, perioperative parameters, and the presence of BNC were documented. Univariate and multivariate analyses were conducted to identify the risk factors. RESULTS: A total of 2% (20/1008) BPH patients developed BNC postoperatively and the median occurring time was 5.8 months. Particularly, the incidences of BNC were 4.7% and 1.3% in patients underwent Bipolar-TURP and TUEP respectively. Preoperative urinary tract infection (UTI), elevated PSA, smaller prostate volume (PV), bladder diverticulum (BD), and B-TURP were significantly associated with BNC in the univariate analysis. Further multivariate logistic regression demonstrated preoperative UTI (OR 4.04, 95% CI 2.25 to 17.42, p < 0.001), BD (OR 7.40, 95% CI 1.83 to 31.66, p < 0.001), and B-TURP (OR 3.97, 95% CI 1.55 to 10.18, p = 0.004) as independent risk factors. All BNC patients were treated with transurethral incision of the bladder neck (TUIBN) combined with local multisite injection of betamethasone. During a median follow-up of 35.8 months, 35% (7/20) of BNC patients recurred at a median time of 1.8 months. CONCLUSION: BNC was a low-frequency complication following transurethral surgery of prostate. Preoperative UTI, BD, and B-TURP were likely independent risk factors of BNC. TUIBN combined with local multisite injection of betamethasone may be promising choice for BNC treatment.

Tamsulosin 0.8 mg daily dose in management of BPH patients with failed tamsulosin 0.4 mg monotherapy and unfit for surgical intervention.

AIM: This study aims to evaluate the effectiveness and safety of administering double-dose tamsulosin (0.8 mg) for treating patients with benign prostatic hyperplasia (BPH) who have not responded to the standard single dose of tamsulosin (0.4 mg) and are deemed unsuitable for transurethral resection (TUR) intervention. MATERIALS AND METHODS: Between November 2022 and July 2023, we prospectively analyzed 111 patients who were experiencing severe BPH symptoms. These patients received a double dose of tamsulosin for one month. We collected baseline characteristics such as age, body mass index, and underlying medical conditions. Various parameters including the International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA) levels, prostate volume, peak urinary flow rate (Qmax), voided volume, and post-void residual volume were evaluated before and after treatment. RESULTS: All 111 patients completed the study. The mean age, PSA level, and prostate volume were 63.12 ± 4.83 years, 3.42 ± 0.93 ng/ml, and 50.37 ± 19.23 ml, respectively. Of these patients, 93 showed improvement in Qmax, post-void residual volume, and IPSS score (p-value = 0.001). The total IPSS score and total Qmax improved from 24.03 ± 2.49 and 7.72 ± 1.64 ml/sec to 16.41 ± 3.84 and 12.08 ± 2.37 ml/sec, respectively. CONCLUSION: Double-dose 0.8mg tamsulosin as an alpha-blocker therapy appears to be a viable temporary management option for BPH patients who have not responded to the standard single dose 0.4mg tamsulosin and are not suitable candidates for TUR intervention.

Delayed hematuria after prostatic photovaporization: risk factors to know.

OBJECTIVE: characterize delayed hematuria (DH) after photoselective vaporization of the prostate (PVP) and identify its associated risk factors. METHODS: 1014 patients who underwent PVP at an expert center, from September 2005 through December 2021, were prospectively enrolled in a database registry. Risk factors of DH included age, prostate volume, ASA score, history of BPH surgery, history of prostate cancer, use of anticoagulation or 5ARIs, concomitant procedure, operative factors, and the duration of follow-up. RESULTS: The median operating time was 60 ± 11 min. The median specific applied energy was 318,500 Joules ± 101,347. After PVP, the mean catheterization duration was 1.6 days with a postoperative hospitalization time of 1.8 days. The median follow-up was 52 months (range 2-95 months). Hematuria occurred in 206 patients (20.3%), with 10% requiring an ER visit and 8.3% requiring hospital admission, transfusion or endoscopic clot removal. Almost 80% of hematuria episodes occurred within the first 3 months. The overall retreatment rate for clot retention was 3.7% after a mean time of 50 months. Hematuria-free survival was 97.2% after 1 year, and 89.3% after 4 years. Delayed hematuria occurred in 32 patients (3.1%). In the multivariate analysis, age, preoperative prostate volume, anticoagulant use, total applied energy, lasing time and operative time were identified as risk factors for delayed hematuria after PVP. CONCLUSION: Larger prostate volume, longer operative time, longer lasing time, and use of oral anticoagulation increase the odds of delayed hematuria after PVP, while older age is protective.

Analysis of urinary retention after endoscopic prostate enucleation and its subsequent impact on surgical outcomes.

PURPOSE: Postoperative urinary retention (PUR) is a common complication after prostate enucleation, which leads to an increased length of hospital stay and decreased postoperative satisfaction. This study determined the predictive factors of postoperative urine retention within 1 month after prostate enucleation and investigated whether PUR influences surgical outcomes at the 2-week, 3-month, and 6-month follow-up time points. METHODS: Data were collected from the electronic medical records of 191 patients with benign prostatic obstruction (BPO) during October 2018 to September 2021. Of them, 180 patients who underwent thulium laser or plasma kinetic enucleation of the prostate (ThuLEP, PKEP) were separated into the PUR group (n = 24) and the non-PUR (NPUR) group (n = 156). Uroflowmetry and the International Prostate Symptom Score (IPSS) questionnaire were followed up at 2 weeks, 3 months, and 6 months postoperatively. RESULTS: The PUR group had a significantly higher percentage of patients with type 2 diabetes mellitus (DM) than the NPUR group. Postoperatively, compared with the NPUR group, the PUR group had significantly less improvement in changes in the IPSS Quality of Life scores at 2 weeks, the total IPSS(International Prostate Symptom Score) at all follow-up times, the IPSS-S(IPSS storage subscores) at 2 weeks and 3 months, and the IPSS-V(IPSS voiding subscores) at all follow-up times. Predictive factors for PUR include lower preoperative maximum urinary flow (Qmax), lower preoperative total IPSS, and higher operation time. CONCLUSION: Lower preoperative Qmax, lower IPSS scores, and longer operation time were risk factors for PUR. Furthermore, PUR could be a prognostic factor for prostatic enucleation surgical outcomes.

Impact of age and anterior fibromuscular stroma preservation on post-enucleation voided volume.

PURPOSE: This study is centered on the critical role of anterior fibromuscular stroma (AFS) preservation in prostate enucleation, an emerging strategy aimed at minimizing postoperative urinary incontinence-a common concern in benign prostatic hyperplasia (BPH) surgeries. By focusing on postoperative voiding volumes (VV), our research investigates the efficacy of AFS preservation. This approach, distinct in its methodology, is hypothesized to improve urinary function post-surgery, thereby offering a potentially significant advancement in BPH surgical treatments. MATERIALS AND METHODS: A retrospective analysis was conducted, comparing patients who underwent prostate enucleation in 2017 without intentional AFS preservation to those in 2019 with this technique. We examined variables including age, BMI, diabetes, hypertension, and preoperative VV to assess their effect on post-catheter removal VV. The study's methodology includes a thorough review of the primary statistical analysis methods employed. RESULTS: Our analysis indicates that while the 2017 and 2019 cohorts were similar in most preoperative parameters, the 2019 group that underwent AFS-preserved surgery showed a significant improvement in postoperative VVs. This was less pronounced in the patient group aged over 70, underscoring the importance of this demographic in our study. CONCLUSIONS: The study concludes that intentional preservation of AFS during prostate enucleation positively impacts early postoperative VVs, with limited improvement in older patients. These findings highlight the potential of AFS preservation not only in enhancing urinary outcomes post-surgery but also in shaping future BPH surgical procedures and research directions.

Real world propensity score matched analysis evaluating the influence of en-bloc vs. non en-bloc techniques, energy and instrumentation on enucleation outcomes for large and very large prostates.

PURPOSE: The primary aim of the study was to evaluate if en-bloc vs. non en-bloc made a difference to intra-, peri- and post-operative surgical outcomes of anatomical endoscopic enucleation (AEEP) in large (> 80 cc) and very large prostates (> 200 cc). The secondary aim was to determine the influence of energy and instruments used. METHODS: Data of patients with > 80 cc prostate who underwent surgery between 2019 and 2022 were obtained from 16 surgeons across 13 centres in 9 countries. Propensity score matching (PSM) was used to reduce confounding. Logistic regression was performed to evaluate factors associated with postoperative urinary incontinence (UI). RESULTS: 2512 patients were included with 991 patients undergoing en-bloc and 1521 patients undergoing non-en-bloc. PSM resulted in 481 patients in both groups. Total operation time was longer in the en-bloc group (p < 0.001), enucleation time was longer in the non en-bloc group (p < 0.001) but morcellation times were similar (p = 0.054). Overall, 30 day complication rate was higher in the non en-bloc group (16.4% vs. 11.4%; p = 0.032). Rate of late complications (> 30 days) was similar (2.3% vs. 2.5%; p > 0.99). There were no differences in rates of UI between the two groups. Multivariate analysis revealed that age, Qmax, pre-operative, post-void residual urine (PVRU) and total operative time were predictors of UI. CONCLUSIONS: In experienced hands, AEEP in large prostates by the en-bloc technique yields a lower rate of complication and a slightly shorter operative time compared to the non en-bloc approach. However, it does not have an effect on rates of post-operative UI.

Transperineal laser ablation (TPLA) of the prostate for benign prostatic obstruction: the first 100 patients cohort of a prospective, single-center study.

PURPOSE: Transperineal laser ablation (TPLA) is a new minimally-invasive surgical treatment for patients with benign prostatic obstruction (BPO). We report the perioperative and mid-term functional results of the first 100 consecutively patients undergoing TPLA at our institution. METHODS: Clinical data from consecutive patients undergoing TPLA at our institution from April 2021 to July 2023 were prospectively collected. Primary endpoints were the postoperative changes in IPSS, QoL and MSHQ 3-item questionnaires and in Qmax and post-void residual volume (PVR). RESULTS: Overall, 100 consecutive patients underwent the procedure. Median age and prostate volume were 66 (IQR 60-75) years and 50 (IQR 40-70) ml, respectively. In the cohort, 14 (14%) patients had an indwelling catheter and 81 (81%) were under oral BPO therapy at the time of TPLA. Baseline median Qmax (ml/s) and PVR (ml) were 9.1 (IQR 6.9-12) and 90 (IQR 50-150), respectively, while median IPSS and QoL were 18 (IQR 15-23) and 4 (IQR 3-4). At all the follow-up timepoints, the evaluated outcomes on both symptoms and functional parameters showed a statistically significant improvement (p < 0.001). Antegrade ejaculation was preserved in all sexually active patients. No postoperative Clavien-Dindo > 2 complications were recorded. CONCLUSIONS: TPLA represents a safe option for selected well-informed patients swith LUTS due to BPO. Our prospective study confirms the feasibility and favorable perioperative and functional outcomes in a real-world cohort with heterogenous prostate volumes and patient characteristics.

UroLift to preserve seminal parameters in young male with LUTS from BPH.

PURPOSE: Prostatic urethral lift has been an effective ejaculation sparing treatment for benign prostatic hypertrophy. The aim of this study was to evaluate the effect on male semen parameters. METHODS: Between July 2014 and January 2022, 20 young men with urinary symptoms of BPH, unresponsive to drug treatment and motivated to preserve ejaculation for eventual paternity, underwent UroLift. Semen analysis was performed before and 6 month after surgery with evaluation of pH, volume, sperm concentration, total motility, vitality and morphology according to WHO 2011. All underwent digital rectal examination, transrectal prostate ultrasound to measure prostate volume, PSA, uroflowmetry, cystoscopy and urodynamics test if necessary. Objective and subjective urinary function was scheduled at 1, 3, 6, 12 month than yearly with UFM, IPSS, IIEF-5, and MSHQ-EjD-SF. RESULTS: At a mean follow-up of 36 month (range 12 to 63), no retroejaculation or changes in seminal parameters occurred. Mean age was 44.5 (range 36.5 to 48) years. Mean operative time was 15 (range 10 to 20) min and 2.5 (range 2 to 4) implants per patients were used. At 6 month there were no difference in terms of total sperm count, volume, pH, motility, vitality, morphology, liquefaction, leucocytes (p = 0.9; p = 0.8; p = 0.7; p = 1; p = 1; p = 1; p = 0,2; p = 0.5). At last, Q-max increased by 64.4% (p = 0.001), post-void residual volume decreased by 66.6% (p = 0.016), and IPSS decreased by 60% (p < 0.001). IIEF and MSHQ-EjD-SF were preserved (p = 0.14, p = 0.4). CONCLUSIONS: UroLift appears safe technique to correct LUTS from BPH in young men desirous to preserve seminal analysis.

Rezum water vaporization therapy versus transurethral resection of the prostate in the management of refractory urine retention: matched pair comparative multicenter experience.

PURPOSE: To compare the efficacy of Rezum with a matched cohort of patients undergoing transurethral resection of the prostate (TURP) for catheter-dependent urine retention secondary to benign prostate hyperplasia (BPH). METHODS: A retrospective review was performed for consecutive catheter-dependent patients who underwent Rezum for BPH. Patients were matched and compared with a similar cohort undergoing TURP, using non-inferiority analysis on propensity score-matched patient pairs. Patients were followed up at 1, 3, 6 and 12 months by international prostate symptoms score (IPSS), quality of life (QoL) index, peak flow rate (Qmax) and postvoid residual urine (PVR). RESULTS: Eighty-one patients undergoing Rezum were compared with equal number of matched patients who undergoing TURP. Patients undergoing Rezum experienced significantly shorter operation time (25.5 ± 8.7 vs. 103.4 ± 12.6 min; p < 0.001), lower intraoperative bleeding (2.4% vs. 20.7%, p < 0.001), shorter hospital stay (1.2 ± 0.9 vs. 2.4 ± 1.3 d, p < 0.001) and longer catheter time (12.6 ± 6.0 vs. 2.3 ± 1.2 d, p < 0.001), with no need for transfusion. Successful postoperative voiding was comparable between both arms (90.2% vs. 92.7%, p = 0.78), respectively. Despite patients undergoing TURP had significantly better voiding outcomes after 1 and 3 months, both groups were comparable after six and 12 months in terms of mean IPSS (11.1 ± 6.4 vs. 10.8 ± 3.4, p = 0.71), QoL indices (2.4 ± 1.6 vs. 2.1 ± 2.3, p = 0.33) and Qmax (22.0 ± 7.7 v. 19.8 ± 6.9 ml/sec, p = 0.06). CONCLUSION: This study supports the safety and efficacy of Rezum in the management of catheter-dependent patients secondary to BPH, with comparable functional outcomes to TURP. Until a randomized clinical comparison is available, long-term data are crucially recommended to compare the recurrence and reoperation rates.
