Thulium Fiber Versus Holmium:Yttrium-aluminum-garnet Laser for Endoscopic Enucleation of the Prostate: A Systematic Review and Meta-analysis.

BACKGROUND AND OBJECTIVE: Thulium fiber laser (TFL) emerged as a competitor of holmium:yttrium-aluminum-garnet (Ho:YAG) laser for anatomic enucleation of the prostate (AEEP) in men with lower urinary tract symptoms (LUTS) related to benign prostatic obstruction (BPO). The aim was to compare the surgical outcomes of Ho:YAG and TFL for AEEP. METHODS: A literature search was conducted to identify reports published from inception until January 2024. The Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed to identify eligible studies. The coprimary outcomes were the postoperative International Prostate Symptom Score (IPSS), IPSS-Quality of Life (IPSS-QoL), and peak urinary flow (Qmax). KEY FINDINGS AND LIMITATIONS: Five studies met our inclusion criteria, and data from 1287 and 1555 patients who underwent AEEP with Ho:YAG (holmium laser enucleation of the prostate [HoLEP]) and TFL (thulium fiber laser enucleation of the prostate [ThuFLEP]), respectively, were reviewed. ThuFLEP was associated with a better IPSS at 3 mo even if the difference was not clinically significant (mean difference [MD] 0.59, 95% confidence interval [CI]: 0.29-0.88; p < 0.001). No difference was found for IPSS at 6-12 mo (p = 0.9), and IPSS-QoL at 3 mo (p = 0.9) and 6-12 mo (p = 0.2). HoLEP was associated with a better Qmax at 3 mo (MD 1.41 ml/s, 95% CI: 0.51-2.30; p = 0.002) and ThuFLEP at 6-12 mo (MD -2.61 ml/s, 95% CI: -4.68 to 0.59; p = 0.01), but the differences were not clinically significant. No difference was found in the major (p = 0.3) and overall (p = 0.3) complication rates. HoLEP was associated with shorter enucleation (MD -11.86, 95% CI: -22.36 to 1.36; p = 0.03) but not total operative time (p = 0.5). CONCLUSIONS AND CLINICAL IMPLICATIONS: The present review provides the most updated evidence on the impact of Ho:YAG and TFL in AEEP, demonstrating that these two energy sources are effective in relieving bothersome LUTS in men with BPO. PATIENT SUMMARY: Thulium fiber laser is a new energy source that can be used safely for performing endoscopic enucleation of the prostate in men with bothersome symptoms associated with benign prostatic enlargement.

Combined holmium laser enucleation of the prostate with high-intensity focused ultrasound in treating patients with localized prostate cancer in a prostate with volume > 60 g: Oncological and functional outcomes from single-institution study.

OBJECTIVE: To assess the efficacy and safety of combined High-Intensity Focused Ultrasound (HIFU) and Holmium Laser Enucleation of the Prostate (HoLEP) in treating patients with both localized prostate cancer (PCa) and prostate > 60 g. METHODS: All patients who underwent HIFU for treatment of localized PCa were prospectively enrolled in our study. We reviewed records of patients undergoing procedures from January 2016 to January 2023. For patients with prostate sizes > 60 g, HoLEP was offered before HIFU to prevent worsened urinary symptoms post-treatment. Oncological outcomes-prostatic-specific (PSA) kinetics, recurrence rates, treatment failure - and functional results-Sexual Health Inventory for Men (SHIM), International Prostate Symptoms Score (IPSS), and urinary complications were compared between patients undergoing combined HoLEP and HIFU with those underwent HIFU-monotherapy. RESULTS: Among 100 patients, 74 underwent HIFU-monotherapy and 26 underwent the combined HoLEP and HIFU. The majority had intermediate-risk PCa (67%). Pathologic assessment of HoLEP specimens showed no tumor evidence in 57% of cases. In comparison to the HIFU-only group, the combined group exhibited significantly lower PSA metrics across various intervals, however, no differences were found regarding overall and infield recurrences and treatment failure rates. While the combined treatment initially resulted in higher incontinence rates and shorter catheterization durations (P < 0.001), no significant difference in IPSS was observed during subsequent follow-ups. CONCLUSION: HoLEP and HIFU can be safely combined for the treatment of PCa in patients with >60 g prostate volume without compromising early oncological outcomes thereby expanding the therapeutic scope of HIFU in treating patients with localized PCa and large adenomas.

Analysis of Postoperative Urinary Incontinence and Influencing Factors of Transurethral Holmium Laser Enucleation of the Prostate.

INTRODUCTION: Aims of the study were to investigate the related factors of urinary incontinence after transurethral holmium laser enucleation of the prostate (HoLEP) and to provide guidance for clinical urinary control of HoLEP. METHODS: The clinical data of 548 patients who underwent HoLEP were retrospectively analyzed. The patients were followed up for the occurrence of urinary incontinence in the short term (2 weeks), medium term (3 months), and long term (6 months) after HoLEP. RESULTS: Among the 548 benign prostatic hyperplasia patients, 79 cases (14.42%) had urinary incontinence at 2 weeks, 19 cases (3.47%) at 3 months, and 2 cases (0.36%) at 6 months after surgery. Logistic regression analysis showed that age, prostate volume, diabetes mellitus, operation time, prostate tissue weight, and histological prostatitis were risk factors for recent urinary incontinence (p < 0.05). Age, diabetes, and operation time were risk factors for mid-term urinary incontinence (p < 0.05). The incidence of long-term urinary incontinence was low and no risk factor analysis was performed. CONCLUSIONS: For good urinary control after HoLEP, in addition to surgery-related factors such as surgical skills, proficiency, and precise anatomy, patients' risk factors should also be paid attention to in order to improve postoperative urinary control more effectively and reduce the incidence of urinary incontinence.

A novel technique for thulium laser enucleation of the prostate: anterior releasing with ThuLEP (ARTh technique).

Thulium laser enucleation of the prostate (ThuLEP) is a highly effective approach to the treatment of benign prostatic hyperplasia. We present here a description of the "ARTh Technique" and the benefits it offers in terms of improved visualization, short operation times, and easy recognition of the dissection plane, describing specifically the anterior release (AR) technique using ThuLEP(Th). Included in this retrospective study were 32 consecutive patients operated on between January 2022-November 2022. Parameters were measured before and after the procedure: the International Prostate Symptom Score(IPSS), maximum flow rate(Qmax), post-void residual urine(PVR) prostate-specific antigen(PSA), prostate volume, operation-time, morcellation-time, catheterization-time and presence of transient urinary incontinence, and compared. The median age of patients undergoing enucleation of the prostate using the ARTh technique was 64 years (range: 44-83). The median prostate volume of the patients was 83.5 ml(50-128 ml), preoperative-IPSS was 24.8(15-33), postoperative-IPSS was 7(5-11), preoperative-Qmax was 8.1 ml/Sects. (5-11.5 ml/sec), postoperative-Qmax was 26.9 ml/Sect. (20.8-34 ml/sec), preoperative-PVR was 145 ml(75-258 ml), postoperative-PVR was 36.2 ml(0-66 ml), total operation time was 51.4 min(28-82 min), enucleation time was 36.9 min(19-51 min) and morcellation time was 15.3 min(8-27 min). The ARTh technique is a safe procedure that allows the surgeon to easily recognize and adhere to the defined dissection plane, thus decreasing operation times, significantly reducing the rate of postoperative transient urinary incontinence (TUI).

Early experience of "En bloc" holmium laser enucleation of the prostate in Saudi Arabia.

Purpose: Holmium laser enucleation of the prostate (HoLEP) showed higher efficacy than transurethral resection for treating benign prostatic hyperplasia (BPH). The present study aims to report the outcome of BPH treatment by HoLEP in a tertiary center. Patients and Methods: An observational prospectively collected data for consecutive symptomatic BPH patients undergoing HoLEP between January 2020 and December 2021. Demographic and perioperative data were collected with the International Prostate Symptom Score (IPSS), quality of life, peak flow rate (Qmax), residual urine postvoid residual (PVR), and prostate-specific antigen (PSA) changes, in addition to perioperative and late adverse events. Results: One hundred patients were included with a median age of 73 years (range 65-80). The IPSS improved by 80% postoperatively (25 vs. 5, P < 0.001). Similarly, Qmax significantly improved. Seven patients were found to have incidental prostate cancer. No patient needed a perioperative blood transfusion. Compared to its preoperative values, follow-up PSA has been reduced by 75% (P < 0.001). Urethral stricture and bladder neck contracture were noted in < 2% of the patients. Conclusions: HoLEP is feasible for all prostate sizes and a safe and effective treatment for BPH patients; our results are consistent with the reported data in the literature regarding functional outcomes, complication rates, and urinary incontinence rates.

Acquired Urethral Diverticulum After Holmium Laser Enucleation of the Prostate: A Case Report.

Acquired urethral diverticula (UD) in males is an uncommon entity, and it is rarely reported after an open simple prostatectomy or transurethral resection of the prostate. Here, we report a unique case of a UD presenting after holmium laser enucleation of the prostate (HoLEP) in a 69-year-old male with a prostate of 372 g who had five episodes of urine retention over one year despite combined medical treatment with tamsulosin 0.8 mg and finasteride 5 mg. The patient also has elevated prostate-specific antigen (PSA) with five negative prostate biopsies over the last few years. The procedure lasted six hours with difficult morcellation due to beach balls that took 3.5 hours. There were no intraoperative complications. However, he continued to have mixed urine incontinence and recurrent (six) episodes of urinary tract infection (UTI) in the first postoperative year. On evaluation, his urodynamic study did not reproduce stress urinary incontinence (SUI); however, cystoscopy and retrograde urethrogram diagnosed a 6-cm UD in the bulbar penile urethra with penoscrotal mass. The patient underwent urethral diverticulectomy and urethroplasty with a buccal mucosa graft to correct the defect. Six months after his urethral reconstruction, he continued to have mixed urine incontinence needing two pads/day. Although male UD is a rare condition, our case report seeks to heighten awareness of such a potential rare complication in men with recurrent UTIs and refractory urinary incontinence after prolonged HoLEP for extremely large prostates.

Persistent Lower Urinary Tract Symptoms After BPH Surgery.

PURPOSE OF REVIEW: Lower urinary tract symptoms (LUTS) after surgical management for BPH pose a significant clinical challenge for urologists. Despite high success rates in relieving LUTS, there is a subset of patients who experience persistent symptoms after intervention. In this review article, we describe the management of patients with new or persistent LUTS after endoscopic bladder outlet surgery. RECENT FINDINGS: Previously, the goal for BPH management was to remove as much adenomatous tissue as possible. While potentially effective, this may lead to unwanted side effects. There has been a recent paradigm shift for new minimally invasive surgical therapies (MIST) that strategically treat adenomatous tissue, adding potential complexity in managing patients with new or residual symptoms in the postoperative setting. There is a paucity of literature to guide optimal workup and care of patients with persistent LUTS after surgical management. We characterize patients into distinct groups, defined by types of symptoms, irritative versus obstructive, and timing of the symptomatology, short term versus long term. By embracing this patient-centered approach with shared decision management, clinicians can optimize outcomes efficiently improving their patients' quality of life.

Incidental prostate cancer after holmium laser enucleation of the prostate: Critical analysis of independent risk factors and impact on surgical outcomes.

Objectives: The objectives of this study are to evaluate the impact of incidental prostate cancer (iPCa) and its different grade group (GG) on the surgical outcomes of holmium laser enucleation of the prostate (HoLEP) and, furthermore, to assess the independent risk factors associated with the detection of iPCa. Patients or materials and Methods: A retrospective chart review was conducted at a single institution for HoLEP cases that were performed between 2017 and 2022. Patients with a preoperative diagnosis of prostate cancer and those without baseline prostate-specific antigen (PSA) levels within 1 year were excluded. Four hundred seventeen patients were divided into three groups: benign prostatic hyperplasia-377; clinically insignificant (GG 1)-29; and clinically significant prostate cancer (GG 2-5)-11. The preoperative parameters analysed included age, body mass index, race/ethnicity, use of 5-alpha-reductase inhibitors, PSA, prostate size, PSA density, and history of negative prostate biopsy. To evaluate the association between clinical and demographic variables, a multivariable-adjusted logistic regression analysis was performed. We also assessed intraoperative and post-operative outcomes among these three groups. Results: A total of 417 patients were analysed; 40 (9.6%) patients had iPCa, of which 29 (72.5%) and 11 (27.5%) were clinically nonsignificant and significant prostate cancer, respectively. Of all the demographic and preoperative variables analysed, hypertension was significantly associated with overall prostate cancer diagnosis (p < 0.05), and no other variable including patient age, preoperative PSA, PSA density, prostate size, or prior prostate biopsy were associated with increased risk of overall prostate cancer or clinically significant prostate cancer diagnosis. Most cases of iPCa were GG1, and 34 (85%) were managed with active surveillance. Conclusion: The rate of iPCa after HoLEP was 9.6%, with most cases being GG 1 (72.5%) and managed through active surveillance. Age, prostate size, baseline PSA, and prior negative prostate biopsies were not associated with increased risk of iPCa.

One-year outcomes after prostate artery embolization versus laser enucleation: A network meta-analysis.

Background: Although holmium laser enucleation (HoLEP) is considered a size-independent procedure for treatment of an enlarged prostate, prostate artery embolization (PAE) is emerging as an alternative modality to treat moderate and large benign prostatic hyperplasia. This study aims to compare the early post-operative and short-term efficacy of PAE and HoLEP. Methods: PubMed, Cochrane Library and EMBASE databases were searched. Network meta-analysis was performed following PRISMA-N-guidelines. Post-operative parameters analysed include international prostate symptom score (IPSS), quality of life (QOL), post-void residual urine (PVR), maximal uroflow rate (Qmax) and serious adverse events (SAE). Random effects model calculated weighted mean differences (WMD). If 95%CI crossed the line of no effect (WMD = 0), evidence indicated no statistically significant difference between treatments compared. Results: Qualitative and quantitative syntheses included 20 and 18 studies with 1991 and 1606 patients, respectively. At 3 months, there was no statistically significant difference between PAE and HoLEP in IPSS score improvement [WMD: -2.21: 95%CI: (-10.20, 5.78), favouring PAE], QoL score improvement [WMD: -0.22:95%CI: (-1.75, 1.32), favouring PAE] and PVR improvement [WMD: 26.97: 95%CI: (-59.53, 113.48), favouring HoLEP]. However, PAE was found inferior to HoLEP for Qmax improvement [WMD: 8.47, 95%CI: (2.89, 14.05), favouring HoLEP]. At 1-year follow-up, there was no statistically significant was found between PAE and HoLEP for IPSS score improvement [WMD:6.03, 95%CI: (-1.30, 13.35)], QoL score improvement [WMD: 0.03, 95%CI: (-1.19, 1.25)], PVR improvement [WMD:4.11, 95%CI: (-32.31, 40.53)] and Qmax improvement [WMD:2.60, 95%CI: (-2.20, 7.41)] with all differences favouring HoLEP. PAE was superior to HoLEP for SAE [PAE vs. HoLEP-OR: 0.68, 95%CI: (0.25, 1.37)]. Conclusion: HoLEP was superior to PAE at 3 months for Qmax improvement. There was no significant difference in IPSS, QoL, PVR and Qmax improvement at 1 year between PAE and HoLEP. PAE was also associated with lesser SAE compared to HoLEP. Studies on the long-term outcome of PAE are needed to establish the durability of early outcomes after PAE.

Patient reported outcome and quality of life measured by a simple questionnaire in patients with symptomatic benign prostate hyperplasia treated by holmium laser enucleation of the prostate (HoLEP).

Introduction: Holmium Laser Enucleation of the Prostate (HoLEP) is established as an effective transurethral treatment option for LUTS due to BPH with improved postoperative outcome. The aim of this study was to evaluate the medium-term results by patient reported outcome measurement and to detect potential risk factors for postoperative complications or impaired outcome. Methods: We performed a retrospective single-center cohort study including all patients undergoing HoLEP in the study center between April 2019 and December 2021. Therefore, perioperative parameters and postoperative outcome was documented and all patients were asked for their outcome (PROM), complications, IPSS, QoL and changes in sexual and continence function by a questionnaire at a single time point. Results: In the study period, a total of 541 patients with a mean age of 72.5 ± 8.4 years were treated by HoLEP in the study center. 71.7% of the questionnaires were returned after a mean observation period of 14.9 ± 6.3 month. 91% of the patients reported to the single-timepoint questionnaire reporting a good satisfaction with the procedure and a low postoperative complication rate. The international prostate symptom score could be reduced significantly to 6.2 ± 5.7 (preoperative 19.0 ± 7.2; p < 0.001). Patients with an ASA score ≥ 3, prostate volume > 80 ml, medication with platelet inhibitors or DOAK or preoperative need of an indwelling catheter didn't show an increased complication rate. Conclusion: The overall satisfaction with the procedure and its results are high. We could not identify any independent risk factors for postoperative complications after HoLEP. The used questionnaire is a simple tool for postoperative patient reported outcome measurement with a good correlation to clinical parameters.

Holmium laser enucleation of the prostate as a secondary surgery following prostatic urethral lift.

Introduction: Prostatic urethral lift is a treatment option for benign prostatic hyperplasia, yet information on surgeries following this procedure is scarce. Case presentation: A 71-year-old man with persistent urinary retention following prostatic urethral lift underwent a secondary holmium laser enucleation of the prostate. The morcellation procedure, complicated by the presence of implants from the previous surgery, broke the morcellator blade. The fragmented blade was successfully retrieved without any organ damage. Postoperatively, the patient encountered no complications and showed improvement in his urinary symptoms. Conclusion: This case highlights the potential risk of device breakage when a secondary surgery, specifically the morcellation process, is performed following prostatic urethral lift. Care must be taken to prevent interaction between the implants and the morcellator. Our case demonstrates the efficacy of holmium laser enucleation of the prostate as a salvage surgical intervention for patients in whom prostatic urethral lift has failed.

Evaluating the effects of preoperative treatment with 5-alpha reductase inhibitors in holmium laser enucleation of the prostate.

INTRODUCTION AND AIM: Patients treated with HoLEP are frequently treated with previous treatments, including 5-alpha-reductase inhibitors (5-ARIs). We investigated the impact of pretreatment with 5-ARIs on perioperative and immediate postoperative parameters in patients treated with HoLEP. MATERIAL AND METHODS: A retrospective study was performed using a prospectively collected database including all patients treated with HoLEP at our center between January 2017 and January 2023. The resected tissue weight, enucleation and morcellation efficiency (enucleation weight/time and morcellation weight/ time), postoperative complications, hospital stay and hemoglobin drop have been analyzed. RESULTS: A total of 327 patients were included. Of these, 173 (52.9%) were treated with 5-ARIs. No differences were found among the perioperative parameters investigated to determine efficiency. No differences were observed in peri- or postoperative complications, hospital stay or hemoglobin drop. CONCLUSIONS: Therapy with 5-ARIs had no impact on the immediate postoperative outcomes of patients treated with HoLEP. In our cohort, we observed that the use of 5-ARIs did not affect surgical efficiency, enucleation or morcellation. Further multicenter studies will be necessary to validate these findings.

Use of the anterior prostatic urethral mucosa preservation technique during holmium laser enucleation of the prostate can reduce postoperative stress urinary incontinence.

INTRODUCTION: Holmium laser enucleation of the prostate (HoLEP) is an effective and safe surgery for patients with benign prostatic hyperplasia. However, some patients exhibit postoperative urinary incontinence. Here, we compared surgical outcomes and incidence of stress urinary incontinence between HoLEP with and without anterior prostatic urethral mucosa preservation (APUMP). METHODS: All patients in this study underwent HoLEP with APUMP technique (APUMP group) and without APUMP technique (no-APUMP group). Enucleation weight, enucleation time, max flow rate increase at 3 months, and urinary incontinence rates immediately after catheter removal and at 1 month after surgery were compared between the groups. RESULTS: In the APUMP (n = 340) and no-APUMP (n = 75) groups, the median enucleation weights were 34.5 and 35.0 g, respectively (p = .982). The corresponding median enucleation times were 33.0 and 46.5 min (p < .01), and median max flow rate increases at 1 month were 10.5 and 9.9 mL/s (p = .89). The urinary incontinence rates immediately after catheter removal were 4.1% and 14.7% (p < .01), and were 3.8% and 12.0% (p < .01) at 1 month after surgery. CONCLUSION: HoLEP using the APUMP technique could be performed with a shorter operative time while maintaining efficacy. The incidence of postoperative urinary incontinence could be decreased by APUMP, indicating that such preservation facilitates the maintenance of urinary continence after surgery.

How Much Do Altmetric Scores Correlate with Bibliometric Scores? Analysis of the Most-Cited 100 Articles about the Holmium Laser Enucleation Prostatectomy.

INTRODUCTION: In addition to bibliometric scores, which are an indicator of academic popularity, it has become frequently used in altmetric scoring that shows the visibility of articles on social media and the internet. In this study, 100 most-cited studies on holmium laser enucleation prostatectomy (HoLEP) were examined, and it was investigated whether the number of citations per year of these studies was affected by altmetric and bibliometric scores. METHODS: The 100 most-cited HoLEP articles between 2000 and 2020 were included in the study. Some bibliometric scores such as h-indexes, impact factors, Scientific Journal Rankings (SJR) scores of the journals and demographics of the articles (such as the number of the citations per year, total number of citations, and total altmetric scores) were recorded. The effects of altmetric and bibliometric scores on the number of citations per year were evaluated by correlation analysis. RESULTS: The median number of citations per year of the articles was 5.88 (4.69-8.42). It was determined that altmetric scores were not an effective factor on the number of citations per year (p = 0.335). A moderate relationship was found between the journal impact factor and the number of citations per year (p < 0.001, r = 0.471, R2 = 0.251). Journal h-index (p < 0.001, r = 0.424, R2 = 0.084), the SJR score (p < 0.001, r = 0.374, R2 = 0.254), and the publication year of the article (p = 0.001, r = 0.326, R2 = 0.023) were significantly but weakly correlated with the median number of citations per year. CONCLUSION: It was seen that the number of citations per year, which is the most important academic quality indicator, is not related to the altmetric scores. In addition, traditional bibliometric parameters still maintain their effectiveness on the number of citations.

Comparison of surgical procedures for benign prostatic hyperplasia of medium-volume prostates: evaluation of the causes of rehospitalization from the French National Hospital Database (PMSI-MCO).

PURPOSE: In France, transurethral resection of the prostate (TURP) is still the most commonly used surgical treatment for medium sized benign prostatic hyperplasia (BPH), but the Holmium Laser Enucleation of the Prostate (HoLEP) and laser vaporization procedures are becoming more common. For these three surgical procedures, we evaluate the initial complications, the short term (3 months) and the 4-12-month postoperative complications necessitating re-hospitalization. METHODS: From the French national hospital data base (PMSI-MCO), all hospitalizations for BPH treatment in 2018 were extracted. We document the complications during the initial hospitalization and any subsequent rehospitalizations during the one-year postoperative period. RESULTS: In 2018, 67,220 patients were treated for BPH: 46,242 TURP, 13,509 HoLEP and 7469 laser vaporization. Age and anticoagulation medications were similar for men treated by the three procedures, but TURP patients were more often hypertensive. Infections and hemorrhagic complications were the most common complications at the initial hospitalization: 17%, 10%, 13% for infections and 15%, 8.1%, 11% for hemorrhagic complications respectively, and TURP performed worse than the other two procedures at the initial hospitalization. During the first three months and then the subsequent nine months, there were fewer complications than initially, with little difference between the three procedures, all differences being less than 1%. CONCLUSION: Laser vaporization techniques led to fewer complications. However, the PMSI-MCO only registers complications during hospitalizations. This study should be extended to non-hospitalized, more minor complications.

Comparison of holmium laser enucleation and transurethral resection of prostate in benign prostatic hyperplasia: a systematic review and meta-analysis.

Transurethral resection of the prostate (TURP) is the gold-standard classical method for the treatment of benign prostatic hyperplasia (BPH). In minimally invasive surgery, holmium laser enucleation of the prostate (HoLEP) is considered an alternative option. In this systematic review and meta-analysis, we aimed to comprehensively evaluate the advantages and disadvantages of TURP and HoLEP the treating BPH. We comprehensively searched PubMed, Cochrane Library, EMBASE, and Web of Science databases for all randomized controlled trials published before 1 December 2022 comparing HoLEP and TURP. The study protocol is registered on INPLASY (DOI: 10.37766/inplasy2023.5.0065). Compared with TURP, HoLEP required longer operation time but shorter catheter duration, hospital stay, and bladder irrigation time, as well as less postoperative irrigation. With HoLEP, maximum urinary flow rate at 12 and 24 months after surgery; post-void residual volume at 1, 6, and 12 months; and International Prostate Symptom Score at 12 months after surgery were superior to those with TURP. HoLEP was associated with significantly lower risk of hyponatremia, blood transfusion, and urethral stricture but greater risk of postoperative dysuria. Compared with TURP, HoLEP had better curative efficacy at 6, 12, and 24 months after operation and lower incidence of adverse events in patients with BPH.

Trends of Benign Prostatic Hyperplasia Procedures in Ambulatory Surgery Settings.

Introduction: Holmium laser enucleation of the prostate (HoLEP) has evidenced-based advantages in treating benign prostatic hyperplasia (BPH) relative to other interventions. Unfortunately, the adoption of HoLEP has remained relatively low in Medicare and the National Surgical Quality Improvement Program populations. HoLEPs role as an inpatient surgical intervention is changing as advancements in the technique and systems have demonstrated the feasibility of same-day discharge. Thus, our objective was to evaluate national HoLEP trends in ambulatory surgery settings from 2016 to 2019. Materials and Methods: The Nationwide Ambulatory Surgery Sample (NASS) is the largest national all-payer database of ambulatory surgical encounters, managed by the Agency for Healthcare Research and Quality. A cross-sectional retrospective analysis of the 2016 and 2019 NASS was performed. Rates of BPH surgeries were calculated and stratified by age, census region, and primary payer to compare across time points for trends. Chi-squared tests and two-sample t-tests were completed for categorical and continuous variables, respectively. Results: The total number of ambulatory BPH surgeries fell 20% between 2016 (n = 124,538) and 2019 (n = 100,593). In 2016, HoLEP lagged behind photoselective vaporization of the prostate (PVP) and transurethral resection of prostate (TURP) with 4.7% of surgeries but rose to the second most common procedure in 2019 with 8.3% of total surgeries. TURP was the most common intervention (62.6% in 2016, 90.7% in 2019). Simple prostatectomy was the most expensive intervention. By U.S. census region, more HoLEPs were carried out in the South (43.1% in 2016, 37.5% in 2019) and Midwest (26.8% in 2016, 31.7% in 2019). Conclusions: Overall, HoLEP uptake is increasing. HoLEP has replaced greenlight PVP as the second most frequently used intervention. The rate of ambulatory HoLEPs has nearly doubled despite a general decrease in the number of surgeries.

A rare case of hyperchloraemic normal anion gap metabolic acidosis due to absorption of normal saline irrigation fluid during holmium laser enucleation of prostate.

Holmium laser enucleation of the prostate (HoLEP) is the preferred technique for surgical management of benign prostatic hyperplasia in prostates over 80 cc in size. A 72-year-old male underwent a HoLEP for catheter-dependent urinary retention in the context of a 204 cc prostate. At the end of the procedure he was clinically overloaded and had developed a combined respiratory and hyperchloremic normal anion gap metabolic acidosis secondary to excessive absorption of normal saline irrigation fluid. He was transferred to the ICU for diuresis and supportive care where he made a full recovery.

Primary prostate Burkitt's lymphoma resected with holmium laser enucleation of the prostate: A rare case report.

BACKGROUND: Primary prostate Burkitt's lymphoma is a rare and aggressive condition with a poor prognosis. Its clinical presentation can be challenging to differentiate from benign prostatic hyperplasia. Given the rarity of primary prostate Burkitt's lymphoma, its diagnosis and treatment remain unclear. CASE SUMMARY: This report presents a case of a 57-year-old male with primary prostate Burkitt's lymphoma, initially misdiagnosed as prostatic hyperplasia. This case's operative process, intraoperative findings and postoperative management are discussed in detail. CONCLUSION: Primary prostate lymphoma is difficult to distinguish from other prostate diseases. Holmium laser enucleation of the prostate (HoLEP), a minimally invasive procedure, is crucial in diagnosing and treating this rare disease. Clinicians should remain vigilant and thoroughly combine physical examination, imaging and test results when encountering patients of younger age with small prostate size but a rapid progression of lower urinary tract symptoms. HoLEP is an essential diagnostic and therapeutic tool in managing primary prostate Burkitt's lymphoma.

Predictive factors for postoperative medication therapy for overactive bladder symptoms after holmium laser enucleation of prostate.

OBJECTIVE: To preoperative factors that could predict the persisting storage symptoms after Holmium laser enucleation of the prostate (HoLEP). METHODS: Medical records of 257 patients who underwent HoLEP between December 2014 and January 2021 were reviewed. Participants with a follow-up period exceeding 6 months were included. Preoperative data, including International Prostate Symptom Score (IPSS), uroflowmetry, prostate size, and prostate-specific antigen, were collected. All participants underwent a preoperative urodynamic study. The correlation between perioperative variables and postoperative medication therapy (antimuscarinics or beta-3 agonists) was assessed. RESULTS: Out of 257 participants in the study, 46 (18.6%) were allocated to the medication group, of which 25 (54.3%) initiated medication therapy postoperatively. The medication group showed worse postoperative IPSS storage symptom score and quality of life score compared to the medication-free group (p = 0.048 and p = 0.002, respectively), but no significant differences were observed in complications or operative variables. In the de-novo medication group, patients had lower preoperative Qmax , larger prostate volume, and smaller maximum cystometric capacity (MCC) compared to the persisting medication group (p = 0.020, p = 0.009, and p = 0.008, respectively). Overactive bladder (OAB) history, terminal detrusor overactivity (DO), and IPSS urgency item were identified as possible predictive factors for post-HoLEP medication use. CONCLUSIONS: Preoperative factors such as OAB history, terminal DO, and IPSS urgency item may predict the need for post-HoLEP medication therapy. Further follow-up studies are warranted to understand the characteristics of the de-novo medication group due to the significant discomfort it can cause to patients.
