Holmium Laser Enucleation of the Prostate in Patients Requiring Anticoagulation

Current era HOLEP with MOSES 2.0 technology compared to the gold standard TURP

PURPOSE

Bipolar TURP is regarded as the gold standard for treatment of BPH. Historically, when compared to HOLEP, bTURP has been found to have shorter operative times and is considered more efficient. We sought to compare the efficiency, efficacy, and safety of current era HOLEP with MOSES 2.0 technology (MOLEP) and bTURP.

METHODS

We performed a retrospective review of patients who underwent bTURP or MOLEP at our institution between 2018 and 2023. Preoperative, intraoperative, and postoperative characteristics were collected for analysis. Analysis was done with SPSS software with significance defined as p < 0.05.

RESULTS

We identified 195 bTURPs and 918 MOLEPs performed at our institution. Men undergoing MOLEP had significantly higher pre-op prostate volume and resected weight (61 ml v 123 ml and 15 g v 70 g, p < 0.001, respectively) when compared to bTURP patients. MOLEP was completed in significantly less OR and procedure time compared to bTURP (66 min vs. 73 min, p < 0.001; 90 min vs. 111 min, p = 0.026, respectively). These results remained significant when controlling for age and prostate volume. At a mean follow up of 3.7 months, HOLEP patients were significantly more likely to be medication (0 vs. 35.84% p < 0.001) and catheter free post-operatively (0.95% vs. 5.68%, p < 0.001) compared to bTURP.

CONCLUSION

In our contemporary cohort, MOLEP is faster and more efficient than bTURP. These findings remained significant despite being performed on larger prostates and in patients more likely to be anticoagulated. Furthermore, MOLEP patients are more likely to remain catheter and medication free at follow-up when compared to bTURP.

Advances in Outpatient Therapies and Treatment of Benign Prostatic Hyperplasia: A Comprehensive Review for Men's Health

Benign prostate hyperplasia (BPH) affects a large number of men and can be treated with behavioral, medical, or surgical treatments. The newest addition to medical therapy is β3-agonists for overactive lower urinary tract symptoms. Multiple new surgical treatments have become available in the past decade, including several clinic-based minimally invasive surgical techniques (eg, UroLift, Rezum, Optilume BPH), OR treatments (eg, Aquablation, single port robotics), and prostate artery embolization. The growth of options allows providers to better tailor BPH treatment to the specific disease factors and patient preferences.

Impact of kidney disease on perioperative outcomes of endoscopic BPH surgery: a propensity score matched analysis from the NSQIP database

INTRODUCTION

To assess the impact of kidney function in patients with BPH undergoing surgery prior to Transurethral resection of prostate (TURP), Laser enucleation of the prostate (LEP), and Laser Vaporization of the prostate (LVP) on operative and post-operative outcomes using the ACS-NSQIP database.

METHODS

The ACS-NSQIP database was reviewed for patients that underwent TURP, LEP and LVP for treatment of patients with BPH between the years of 2008 and 2021. Demographics, comorbidities, bleeding disorders, operative time, and surgical procedure performed were collected for comparison between Kidney function groups: G1, normal/high function; G2-G3, mild/moderate kidney disease; and G4-G5, severe kidney disease. The 30-day peri-operative complications were measured and a multivariate logistic regression analysis was performed while adjusting for all confounding variables. Propensity score matching was performed between the G1 and G4-G5 cohorts.

RESULTS

A total of 83,020 patients were included. On multivariable regression, in the G2-G3 cohort, patients were at significantly increased risk for renal complications with OR = 2.43[1.56-3.79]. After propensity score matching, the G4-G5 cohort showed increased odds of pneumonia OR = 4.02[1.343-12.056], renal complications with OR = 7.62[2.283-25.411], cardiac complications OR = 4.53[1.531-13.411], and sepsis/septic shock OR = 1.76[1.091-2.834]. They also had a higher need for blood transfusion OR = 3.58[2.242-5.714], and prolonged hospital stay with OR = 1.49[1.296-1.723].

CONCLUSION

Pre-operative kidney disease may pose an increased risk of complications for patients undergoing endoscopic BPH surgery. The literature lacks information on the effect of pre-operative kidney disease on endoscopic BPH surgeries. Further studies are required to compare post-operative outcomes of LEP and LVP as compared to TURP across kidney function status.

Redefining Clinically Significant Hematuria After Holmium Enucleation of the Prostate

Introduction and Objective: Holmium laser enucleation of the prostate (HoLEP) is often offered for symptomatic prostatic enlargement at high risk for bleeding. However, prior studies define clinically significant hematuria (CSH) narrowly as the need for blood transfusion or significant decrease in hemoglobin. We sought to evaluate risk factors contributing to a broader definition of CSH, which may contribute to alteration of clinical course. Methods: We analyzed 164 patients in a prospectively maintained database who underwent HoLEP at a single institution across two surgeons from November 2020 to April 2023. HoLEP was performed using Moses 2.0 (Boston Scientific) laser and the Piranha enucleation system (Richard Wolf). We defined CSH broadly as follows: clot retention, return to operating room, perioperative management variation due to hematuria, or continued gross hematuria past 1 month postoperatively. Univariable and multivariable ANOVAs were used. Multivariable analysis of CSH risk based on the use of antiplatelet (AP) agents or anticoagulants included correction for age, enucleation time (surrogate for case difficulty), and prostate volume. Results: 17.7% (29/164) of our patients developed CSH after HoLEP. Longer enucleation time was a mild risk factor for developing CSH (multivariate odds ratio [OR] 1.01, p = 0.02). The strongest predictor of CSH was the use of anticoagulation or AP agents (OR 2.71 p < 0.02 on univariable analysis, OR 2.34 p < 0.02 on multivariable analysis), even when aspirin 81 mg was excluded. Conclusion: With a broadened definition, 18% of patients developed CSH following HoLEP, which impacted the clinical course. Our data suggest that the current definition of significant hematuria is too narrow and does not capture many patients whose clinical course is affected by hematuria. While safe, anticoagulants and APs significantly predicted an increased CSH risk, and patients should be counseled accordingly.

Mini-HoLEP (MILEP) vs HoLEP: a propensity score-matched analysis

BACKGROUND AND PURPOSE

Minimal invasiveness improves outcome in many surgical fields including urology. We aimed to assess intraoperative performance and clinical outcome of miniaturized holmium laser enucleation of prostate (MiLEP) (22FR).

METHODS

We ran a propensity score-matched analysis among all consecutive laser enucleations of prostate performed between 9/2022 and 2/2023. It resulted in two matched comparison groups: MiLEP 22 FR (n = 40) and holmium laser enucleation of prostate (HoLEP 26 Fr) (n = 40). Statistical analysis was performed.

RESULTS

MiLEP was associated with significantly less intraoperative irrigation (20.5 L vs 15 L, p = 0.002E-3), less decrease in body core temperature (0.6°C vs 0.1°C, p = 0.003E-5), and less need for meatal dilation (25% vs 78%, p = 0.01E-3). These parameters were identified as being independent in the multivariate analysis. There was a trend toward less and a shorter period of postoperative stress incontinence (SI) for the MiLEP group compared to the HoLEP group: 15% and 42% (p = 0.01) at 1 month, 8% and 14% (p = 0.07) at 2 months, and 0 and 0.3% (p = 1) at 3 months, respectively. There were no differences in prostatic enucleation effectiveness, operative time, hospital stay, complications, and improvement in the international prostate symptom score and quality of life score.

CONCLUSIONS

MiLEP is feasible and provides better maintenance of body core temperature, reduction in amount of fluid irrigation, and decrease in need for meatal dilation without affecting effectiveness in comparison with HoLEP. MiLEP may reduce early postoperative stress incontinence, thereby shortening the recovery period.

En bloc enucleation of the prostate with early apical release using a high-power (200 W) thulium device: studying a learning curve

OBJECTIVE

The aim of this study was to reveal the learning curve of early apical release en bloc laser prostatectomy using a high-power thulium (200 W) laser device.

METHODS

We obtained data on the initial 60 patients who had thulium laser enucleation of the prostate by a single surgeon between October 2021 and August 2022 to treat the signs and symptoms of benign prostatic hyperplasia at our clinic. The cases were split into three groups, each consisting of 20 patients. Prostate volumes, prostate-specific antigen and hemoglobin levels, the International Prostate Symptom Score, Quality of Life scores, the International Index of Erectile Function-5 scores, and uroflowmetry parameters were documented preoperatively. The enucleation weight, the enucleation and morcellation times, as well as the efficiency, hospitalization, and catheterization durations were calculated. The patients were re-evaluated at 6 months postoperatively, examined for functional results, and compared to baseline conditions.

RESULTS

Enucleation times, morcellation times, enucleation weight, and enucleation efficiency were significantly different among the groups. However, there was no statistically significant difference in total operative time and morcellation efficiency. In terms of postoperative statistics, the reduction in hemoglobin was significantly greater in Group 1 compared to Group 2. Six months after surgery, all groups had comparable validated ratings (International Prostate Symptom Score, Quality of Life, and the International Index of Erectile Function-5) on postoperative examinations. There were no long-term complications in either group throughout the perioperative period.

CONCLUSION

Completing 40 first cases would be sufficient for managing the learning curve for early apical release en bloc thulium laser enucleation of the prostate.

Impact of American Society of Anesthesiologists score on postoperative holmium enucleation of the prostate outcomes and complications

INTRODUCTIONS

The American Society of Anesthesiologists Physical Status Classification System (ASA) is a validated risk stratification method for patients undergoing surgery. There is an increased prevalence of benign prostatic hyperplasia and comorbidities in our aging population. The role of ASA related to postoperative complications in patients undergoing holmium laser enucleation of the prostate (HoLEP) has not been described.

METHODS

A review of our database was performed for patients who underwent HoLEP from July 2018 to December 2020. Patients were stratified based on ASA score. Preoperative, perioperative, and complication data were analyzed using SAS analytics software.

RESULTS

Of 472 patients undergoing HoLEP, 320 (67.8%) were ASA 3-4 patients. There was a statistically significant difference found in age (72.3 ± 9.8 vs. 69.1 ± 9.0 years, p < 0.001), body mass index (BMI) (29.0 ± 5.9 vs. 27.3 ± 4.2, p = 0.004), and use of antiplatelet/anticoagulant medications (14.6% vs. 2.6%, p < 0.001) in the ASA 3-4 group. There was no significant difference between prostate volume (p = 0.158) or catheter-dependent urinary retention (p = 0.376). No difference was found in enucleation time (52.76 ± 24.8 vs. 54.16 ± 23.7 min, p = 0.587), OR specimen weight (70.24 ± 58.5 vs. 81.53 ± 65.9, p = 0.094). or intraoperative complications (2.8% vs. 1.3%, p = 0.330). There were higher postoperative complications in the ASA 3-4 group (12.8% vs. 7.9%, p = 0.03), but no difference in Clavien ≥3 complications (p = 0.068). ASA 3-4 patients had similar postoperative international prostate symptom score (p = 0.159).

CONCLUSION

HoLEP is feasible and effective in patients who are ASA 3-4. The high-risk cohort had an increased rate of low-grade complications. Patients with an ASA score of 3-4 should be counseled regarding a higher rate of low-grade complications.

Neuromuscular Paralysis is not a Barrier to Same Day Catheter Removal After HoLEP

OBJECTIVE

To determine if same day catheter removal is feasible in a population of holmium laser enucleation of the prostate patients who received paralysis and if bladder pressure monitoring could predict successful catheter removal.

METHODS

From February 2021 to February 2022, we evaluated same day catheter removal for patients undergoing holmium laser enucleation of the prostate. Criteria for proceeding with same day catheter removal included: an uncomplicated procedure, continuous bladder irrigation weaned within 120 minutes of arrival to PACU, minimal postoperative hematuria and a bladder pressure over 30 cmH₂0 as measured using the VP Test device (SRS Medical).

RESULTS

One hundred and eight patients were enrolled, with a median age of 68 years (IQR: 62.0-73.0) and prostate volume 80.8cc (IQR: 64.8-112.3). Criteria for catheter removal was met by 83/108 (76.9%) patients. Of those that attempted a trial of void, 69/83 passed for an effective pass rate of 83.1%. Median maximum detrusor pressure for those that passed and failed were 51.0 cmH₂0 (IQR: 40.5 -68.0) and 48.0 cmH₂0 (IQR: 38.8-61.8) [P = .53], respectively. Intraoperative Lasix administration was associated with a higher rate of trial of void (TOV) success and preoperative PVR was associated with lower TOV success, with OR (95%CI) of 5.8 (1.4, 29.5) [P = .02] and 0.6 (0.4, 0.9) [P = .01], respectively.

CONCLUSION

Same day catheter removal is feasible in those who receive neuromuscular paralysis, with a success rate >80%. Bladder pressure monitoring did not assist with differentiating which patients will pass or fail a trial of void. Intraoperative Lasix administration may be helpful in increasing success for same day catheter removal while elevated preoperative PVR was associated with TOV failure.

Predictors of Failed Same-Day Catheter Removal After Holmium Laser Enucleation of the Prostate

OBJECTIVE

To determine factors associated with failure of same-day trial of void (SDTOV) following holmium laser enucleation of the prostate (HoLEP).

BACKGROUND

HoLEP is increasingly utilized for patients with benign prostatic hyperplasia. Advancements in technology have improved operative efficiency and hemostasis making same-day, catheter-free discharge possible.

METHODS

We conducted a retrospective review on 190 patients undergoing HoLEP from July, 2021 to January, 2022 by a single center. We assessed pre- and intra-operative variables associated with our primary outcome: failure of same-day catheter removal. Post-operative complications and outcomes at a ≤7 days and 3-month follow up were examined. Continuous and categorical variables were analyzed using unpaired t-tests (Mann Whitney) and chi-square, respectively. Univariate and multivariable logistic regression models were fitted to examine the associations of failed SDTOV.

RESULTS

Of 190 candidates for a SDTOV, 90% (171/190) were successful. We found no difference between SDTOV success and failures with regards to age, comorbidities, presence of pre-operative urinary retention, anesthesia factors, operative time, volume resected, enucleation time, and morcellation time (all P>0.05). Pre-operatively, 26.3% (50/190) were on antiplatelet and 6.3% (12/190) were on anticoagulation. While pre-operative antiplatelet therapy was not associated with SDTOV failure (P=0.78), pre-operative anticoagulation use was (4.7% vs. 21.1%, P=0.021). Patients who continued anticoagulation through surgery had the highest rate of SDTOV failure (2.3% (4/171) vs. 15.8% (3/19), P=0.023). For those with successful SDTOV, 4.1% (7/171) required catheterization following discharge. At 3 months, no patient required catheterization.

CONCLUSION

On the day of surgery, patients eligible for SDTOV successfully voided 90% of the time. History of preop anticoagulation, whether continued or held, increased SDTOV failure.

Comparison of Emergency Room Visits and Rehospitalization for Bleeding Complications following Transurethral Procedures for the Treatment of Benign Prostatic Hyperplasia: A Population-Based Retrospective Cohort Study

Background: The postoperative bleeding complications associated with laser surgery of the prostate and transurethral resection of the prostate (TURP) were compared. Methods: We used the Taiwan National Health Insurance Research Database to conduct an observational population-based cohort study. All eligible patients who received transurethral procedures between January 2015 and September 2018 were enrolled. Patients who received laser surgery or TURP were matched at a ratio of 1:1 by using propensity score matching, and the association of these procedures with bleeding events was evaluated. Results: A total of 3302 patients who underwent elective transurethral procedures were included. The multivariable Cox regression analysis revealed that diode laser enucleation of the prostate (DiLEP) resulted in significantly higher emergency room risks within 90 days after surgery due to clot retention than the Monopolar transurethral resection of the prostate (M-TURP) (Hazard Ratio: 1.52; 95% Confidence Interval [CI], 1.06–2.16, p = 0.022). Moreover, GreenLight photovaporization of the prostate (PVP) (0.61; 95% CI, 0.38–1.00 p = 0.050) and thulium laser vaporesection of the prostate (ThuVARP) (0.67; 95% CI, 0.47–0.95, p = 0.024) resulted in significantly fewer rehospitalization due to clot retention than did M-TURP. No significant increase in blood clots were observed in patients using comedications and those with different demographic characteristics and comorbidities. Conclusions: Among the investigated six transurethral procedures for Benign prostatic hyperplasia, PVP and ThuVARP were safer than M-TURP because bleeding events and clot retention were less likely to occur, even in patients receiving anticoagulant or antiplatelet therapy. However, DiLEP and holmium laser enucleation of the prostate (HoLEP) did not result in fewer bleeding events than M-TURP.

Anticoagulant but not antiplatelet use is associated with haematuria complications after bladder outflow surgery

Objective:

The evidence on the safety of peri-procedural management of more novel antithrombotic medication in the context of a wider option of bladder outflow obstruction (BOO) procedures is limited. We aimed to assess the risk of delayed discharge or readmission (specifically due to haematuria) for all patients undergoing BOO surgery.

Patients and methods:

Prospective identification of all patients undergoing any type of BOO procedure at a single centre between April and December 2019 was performed. Clinical information was obtained from electronic patient records to scrutinise medications, procedure, delayed discharge and readmission within 30 days of surgery due to haematuria.

Results:

Two hundred forty patients were identified. In all, 78.6% (22/28) of patients on anticoagulants were on novel agents. The delayed discharge rate due to haematuria was 0.58% (1/171) in the no antithrombotic group and 7.14% (2/28) in the anticoagulant-only group. Increased age and perioperative anticoagulant therapy predicated delayed discharge. Readmissions due to haematuria were statistically significant with 1.16% (2/171) readmitted with no antithombotics, compared with 14.3% (4/28) of those on anticoagulants ( p ⩽ 0.01).

Conclusion:

Perioperative anticoagulant use is associated with an increased risk of readmission following BOO surgery. Further work is required to help stratify and lower risk, especially with evolving surgical and medical technologies.

Salvage versus primary holmium laser enucleation of the prostate: trends, outcomes and safety analysis

PURPOSE

To study the safety, efficacy and trends in index procedures leading to salvage holmium laser enucleation of the prostate (S-HoLEP).

METHODS

This was a single-institution retrospective review of HoLEPs performed between 2006 and 2020. Patients who underwent S-HoLEP were compared to those undergoing primary holmium laser enucleation of the prostate (P-HoLEP). The endpoint of primary interest were functional outcomes. Changes in index procedures over the study period were analyzed.

RESULTS

A total of 633 HoLEPs were performed during the study, with 217 being S-HoLEP. The S-HoLEP cohort was older than P-HoLEP cohort, 71.2 years vs 68.8 years (p = 0.03). All other factors were well matched. The most common index procedures prior to S-HoLEP included transurethral resection of the prostate (TURP) (87, 40.1%), transurethral microwave thermotherapy (TUMT) (44, 20.3%), photoselective vaporization of the prostate (PVP) (24, 11.1%) and prostatic urethral lift (PUL) (24, 11.1%). Preoperative prostate volume, IPSS and Q_max were similar between groups. Intra-operatively, S-HoLEP had longer procedure and morcellation times (p = 0.01 and 0.007). Postoperatively, the S-HoLEP cohort had longer catheter duration and hospitalization (both p < 0.001). Postoperative Q_max, IPSS and 90-day complication rates were similar. On temporal analysis, minimally invasive surgical therapies (MIST) have become more prevalent as index procedures.

CONCLUSION

S-HoLEP is safe and efficacious for patients requiring additional BPH surgical intervention. S-HoLEP patients had longer operative times and hospital stays but equivalent postoperative functional outcomes compared to P-HoLEP. As MIST mature and gain traction, it is expected that rates of S-HoLEP will continue to rise.

Outcomes of octogenarians undergoing holmium laser enucleation of prostate

PURPOSE

Holmium laser enucleation of prostate (HoLEP) is an effective surgical procedure in men with BPH. Due to the increase in the use of medical therapy for BPH related lower urinary symptoms more octogenarians are presenting in a delayed fashion with significant symptoms and urinary retention. We evaluate the feasibility and safety of octogenarians undergoing HoLEP.

METHODS

We performed a retrospective review of HoLEPs at our institution from July 2018 to December 2019. Patients were stratified into two groups based on age: < 80 and ≥ 80.

RESULTS

A total of 458 patients were identified, with 74 (16.2%) ≥ 80. In patients ≥ 80, prostate volume was higher (p < 0.0005), there was a higher rate of antiplatelet/anticoagulation (p = 0.029) use, and a lower rate of alpha-blocker use (p = 0.0016). As expected, ASA scores which correlate with increasing number of concomitant diseases were greater in the ≥ 80 cohort (p = 0.016). There was no significant difference in intraoperative complications (p = 0.14), 90 day complication (p = 0.34), readmission rates (p = 0.425) or emergency room visits between groups (p = 0.15).

CONCLUSIONS

Despite higher medical comorbidities and increased rates of anticoagulation in octogenarians, there is no increase in operative or postoperative complication rates. Age alone should not be used as exclusion criteria for HoLEP.

Reimbursement of surgical procedures for benign prostatic hyperplasia: are we disincentivizing complex care?

PURPOSE OF REVIEW

To provide an overview of how surgical benign prostatic hyperplasia (BPH) procedures are compensated in the United States and the implications of the current reimbursement system on the care of patients.

RECENT FINDINGS

The resource-based relative value care system is Medicare's current reimbursement model. There is strong evidence that the current system does not adequately account for complex care. Consequently, for BPH surgical procedures, treatment options best suited for complex patients are not adequately reimbursed which may have implications on healthcare delivery and outcomes.

SUMMARY

Inadequate reimbursement for certain BPH procedures may disincentivize the care of complex patients. Procedures such a holmium laser enucleation of the prostate are well suited for complex patients but have a steep learning curve. The incentive to learn and offer such procedures to complex patients may be unfairly influenced by reimbursement levels, which in the end penalizes patients and the treatments available to them.

Does prior transurethral resection of prostate have a negative impact on the outcome of holmium laser enucleation of prostate? Results from a prospective comparative study

Objectives

To prospectively evaluate safety and efficacy of holmium laser enucleation of prostate (HoLEP) for surgical treatment of recurrent symptoms due to prostatomegaly after prior transurethral resection of prostate (TURP).

Materials and Methods:

We prospectively evaluated 43 patients with a history of TURP who underwent HoLEP (study group). Patients in chronological order who underwent HoLEP without prior TURP were included in the control group. We hypothesized that prior TURP would increase technical difficulties, thereby leading to a reduction in procedure efficiency by 25%. Patients’ demographic, intraoperative, and postoperative data were compared, and statistical analysis was performed.

Results:

Demographic data in both groups were comparable. The average interval between past TURP and HoLEP was 4.22 years. There was no difficulty in identifying the dissection plane in the study group and the difference in the procedure efficiency between the study and the control groups were statistically insignificant (0.75 ± 0.31 g/min-study group vs. 0.69 ± 0.36 g/min-control group; P = 0.665). The intraoperative parameters and postoperative outcomes were comparable in both groups.

Conclusions:

Prior TURP does not negatively impact the outcome of HoLEP in treating symptomatic recurrence for enlarged prostate after initial TURP.

Reasons to go for thulium-based anatomical endoscopic enucleation of the prostate

PURPOSE

To summarize the current evidence and the reasons to go for thulium-based anatomical endoscopic enucleation of the prostate (AEEP).

METHODS

This review discusses the available literature on thulium-based AEEP.

RESULTS

Thulium lasers operate at a wavelength between 1940 and 2013 nm. This wavelength, which has a low penetration depth in water, allows to perform smooth cuts in the prostatic tissue and allows urologists to perform various procedures: resection, vaporization, enucleation, or vapoenucleation of the prostate. Depending on the type of thulium laser, it can be used either in a continuous, or pulsed mode.

CONCLUSION

In recent years, an increasing amount of evidence has described the thulium laser as a minimally invasive and size-independent treatment option for benign prostatic enlargement with excellent long-term results.

Real-World Experience of Holmium Laser Enucleation of the Prostate with Patients on Anticoagulation Therapy

Background: Holmium laser enucleation of the prostate (HoLEP) is a highly effective procedure for benign prostatic hyperplasia that is size independent and has been recommended for patients necessitating antiplatelet (AP) and anticoagulant (AC) medications. Although HoLEP is feasible in AP/AC patients, there is a lack of published results on real-world outcomes of patients on AP/AC therapy undergoing HoLEP. Patients and Methods: We performed a retrospective review of our institutional HoLEP database of demographics, perioperative and postoperative data, and outcomes of patients on AP and AC therapy compared with none. We also further stratified patients on warfarin compared with direct oral anticoagulants (DOACs). Results: Of 472 patients who underwent HoLEP at our institution from July 2018 to December 2019 with data on AP/AC drugs, 30 (6.3%) were on AP and 65 (17.2%) were on AC. One patient continued AP (3.3%), six patients (9.2%) were bridged on AC, and one patient (1.5%) continued AC through the time of HoLEP at the discretion of the prescribing provider. Preoperatively, only age was significantly different among the three groups (p < 0.001). There were no intraoperative differences. Postoperatively, there was a higher 90-day complication rate in AP and AC groups (p = 0.035), but not an increase in emergency department (ED) visits (p = 0.557) or Clavien ≥3 complications (p = 0.16). In comparison of patients on warfarin with DOAC, there was a lower rate of successful voiding trial (p = 0.009), higher 90-day complications (p = 0.003), and more ED visits (p = 0.003) in the warfarin group. Conclusions: HoLEP is safe and effective for patients who require AP or AC therapy. There is no increase in serious complications or worsened postoperative voiding parameters. Of patients on AC, those on DOAC have better outcomes compared with warfarin.

Same Day Discharge is a Successful Approach for the Majority of Patients Undergoing Holmium Laser Enucleation of the Prostate

BACKGROUND

Limited research has focused on success with hospital discharge on the same day of surgery after holmium laser enucleation of the prostate (HoLEP).

OBJECTIVE

To determine the success of same-day discharge in our HoLEP cohort and factors associated with this approach.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective review of our prospectively maintained HoLEP database demonstrated that 473 adult males underwent HoLEP from July 2018 to December 2019 at a tertiary referral center and high-volume HoLEP hospital. Patients were divided into groups according to planned inpatient admission (PIA), successful same-day discharge (SDD), or unplanned admission (UA).

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The PIA, SDD, and UA groups were assessed for differences in preoperative demographic data, perioperative surgical data, and postoperative follow-up data. SDD and UA were then compared to determine if any specific factors predicted UA, including univariate and multivariate logistic regression analyses.

RESULTS AND LIMITATIONS

Age (p = 0.0049), use of anticoagulation (p = 0.037), American Society of Anesthesiologists score of 3-4 (p = 0.0017), and enucleation time (p=0.0178) were significantly higher in the PIA group. Morcellation time (p = 0.0059) and the rate of bedside catheter irrigation (p = 0.04) were higher in the UA group. The SDD group had the highest rate of successful voiding trial (p = 0.0001). Among the three groups, there was no difference in the rate of postoperative complications (p = 0.141). In a comparison of the SDD and UA groups, morcellation time (p = 0.041), the rate of bedside clot evacuation (p = 0.004), and successful voiding trial (p = 0.003) all favored SDD. There was no difference in 90-d complications (p = 0.536). A limitation is the retrospective nature of this study.

CONCLUSIONS

HoLEP can be successfully performed as day surgery without an increase in postoperative complications. HoLEP as day surgery is possible for any patient who does not require admission for medical comorbidities.

PATIENT SUMMARY

Same-day discharge (SDD) after holmium laser enucleation of the prostate (HoLEP) is possible and is successful in 87.4% of patients. Patients with longer morcellation times and with post-procedure hematuria with clots are more likely to have an unplanned admission. Use of a 120-W modulated-pulse laser resulted in a higher rate of SDD success. The culture change to day surgery is time-intensive owing to education of the postsurgical care units and clinic staff, and in our experience took approximately 9 mo to seamlessly integrate SDD as our HoLEP standard of care.

The New American Urological Association Benign Prostatic Hyperplasia Clinical Guidelines: 2019 Update

PURPOSE OF REVIEW

The goal of this paper was to analyze the efficacy of the current modalities available to surgically treat lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH).

RECENT FINDINGS

There have been significant surgical advancements for the treatment of BPH, including an increasing development and utilization of minimally invasive surgical techniques (MISTs). These procedures have varying outcomes that are critical to understand. In addition, MISTs have important adverse effects, though have minimized effects on sexual function when compared to more invasive surgical techniques. It is important for all urologists to be familiar with the surgical techniques available to treat BPH and the updated American Urological Association (AUA) Guidelines. Further studies evaluating efficacy, safety, and sexual functioning will help guide care in the future and evolve practice.

Holmium laser enucleation of the prostate: efficacy, safety and preoperative management in patients presenting with anticoagulation therapy

PURPOSE

We evaluated efficacy and safety profile of patients with anticoagulation therapy (AT) undergoing holmium laser enucleation of the prostate (HoLEP).

METHODS

Within our prospective institutional database (11/2017 to 11/2019), we analyzed functional outcomes and 30-day complication rates of HoLEP patients according to Clavien-Dindo classification (CLD), stratified according to specific AT vs. no AT. Further analyses consisted of uni- and multivariate logistic regression models (LRM) predicting complications.

RESULTS

Of 268 patients undergoing HoLEP, 104 (38.8%) received AT: 25.7% were treated with platelet aggregation inhibitors (PAI), 8.2% with new oral anticoagulants (NOAC) and 4.9% with AT-combinations or coumarins bridged with low molecular weight heparins (LMWH/combination). Patients receiving AT were significantly more comorbid (p < 0.01). Pre- and postoperative maximal flow rates, residual void urine and IPSS at 3 months after surgery were invariably improved after HoLEP for patients with/ without AT. Overall complication rate was 19.5% in patients with no AT vs. 26.1% vs. 27.3 vs. 46.2%, respectively, in patients with PAI, NOAC and LMWH/combination (p < 0.01). Major complications (CLD ≥ 3b) occurred in 6.1% of no AT patients vs. 4.3% vs. 4.5 vs. 0% in patients with PAI, NOAC and LMWH/combination, respectively (p < 0.01). In multivariate LRM, AT was not significantly associated with higher complication rates, whereas high ASA status (OR 2.2, p = 0.04), age (OR 1.04, p = 0.02) and bioptical or incidental prostate cancer (OR 2.5, p = 0.01) represented independent risk factors.

CONCLUSION

Despite higher overall complication rates in AT patients, major complications were not more frequent in AT patients. HoLEP is safe and effective in anticoagulated patients.

Complications of anatomical endoscopic enucleation of the prostate

Transurethral resection of the prostate (TURP) remains the 'gold standard' for surgical treatment of benign prostatic obstruction (BPO). Recently, anatomical endoscopic enucleation of the prostate (AEEP) using holmium laser, thulium laser and plasma, etc., is extensively applied in clinical practice. However, perioperative complications of AEEP are inevitable in spite of lower incidence compared with TURP. This study reviewed the literature related to the aetiology, prevention and treatment of common complications of AEEP, which would contribute to the diagnosis and treatment of BPO.

Laser enucleation of the prostate versus transurethral resection of the prostate: perioperative outcomes from the ACS NSQIP database

PURPOSE

To compare the perioperative outcomes associated with laser enucleation of the prostate (LEP) and transurethral resection of the prostate (TURP) using a national database.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program database was reviewed for patients who underwent TURP or LEP from 2008 to 2016. Baseline demographics, comorbidities, and predisposition to bleeding were compared between TURP and LEP. The 30-day perioperative outcomes including operative time, length of hospital stay (LOS), return to the operating room (OR), bleeding requiring transfusion, and organ system-specific complications were compared between the procedures. A multivariate logistic regression analysis was performed, adjusting for the type of surgery and other covariates.

RESULTS

The series included 37,577 TURP and 2869 LEP procedures. While TURP was associated with a shorter operative time (55.20 ± 37.80 min) than LEP (102.80 ± 62.30 min), the latter was associated with a shorter hospital stay (1.29 ± 2.73 days) than TURP (2.05 ± 5.20 days). Compared to TURP, LEP had 0.52 (0.47-0.58) times the odds of a LOS > 1 day and 0.67 (0.54-0.83) times the odds of developing urinary tract infections. Nevertheless, no difference was found for other postoperative complications, need for transfusion, and return to OR.

CONCLUSION

Real-life data from a large national database confirmed that LEP is a safe and reproducible procedure to treat benign prostatic obstruction. Compared to TURP, LEP was associated with a lower rate of infectious complications and a shorter LOS at the expense of an increased operative time.

Our clinic's first experience with HoLEP

OBJECTIVE:

The present study reports a retrospective evaluation of the first Holmium laser prostate enucleation (HoLEP) cases and their results in our clinic.

METHODS:

Twenty four patients who underwent HoLEP surgery between April 2017 and November 2017 were evaluated for demographic characteristics, duration of operation, amount of hemorrhage, amount of energy used, tissue weight removed, catheterization time and complications. IPSS and uroflowmetry results were compared before and after the surgery.

RESULTS:

Patients with hemoglobin, IPSS, uroflowmetry, and voiding speeds (Qmean, Qmax) were compared before and after the surgery. There was a significant difference in IPSS, Qmean and hemoglobin values but not in Qmax, statistically. Our complications rates were correlated with the literature.

CONCLUSION:

HoLEP stands out as a surgical method that can be applied with high confidence in the treatment of benign prostatic hyperplasia and it has similar functional results to gold standard surgeries, causes fewer complications, improves patient comfort due to short catheterization and hospitalization and is more advantageous regarding cost.

Comparative Study of Holmium Laser Enucleation of the Prostate With MOSES Enabled Pulsed Laser Modulation

OBJECTIVE

To compare outcomes for patients undergoing holmium laser enucleation of the prostate (HoLEP) for lower urinary tract symptoms secondary to benign prostate hyperplasia using 3 different laser fibers and 2 different laser energy modes.

MATERIALS AND METHODS

This is a review of a clinic registry of men with lower urinary tract symptoms secondary to benign prostate hyperplasia who underwent HoLEP between August 2018 and January 2019. Patients were assigned to group 1 (50 patients), group 2 (50 patients), and group 3 (50 patients) based on the HoLEP being completed with either a Slimline 550µm, Slimline 1000µm, or MOSES 550 µm laser, respectively. The groups were compared using SSPS for ANOVA comparison of means and multivariate logistic regression.

RESULTS

Ten patients who underwent concomitant stone surgery (2 PCNL, 8 ureteroscopy , 3 bilateral cases) and 11 patients had bladder stones removed; ancillary procedures did not significantly differ between groups(P = .2). Prostate enucleation times differed significantly (22.5 + 7.3, 16.4 + 6.9, 18.1 + 8.6 minutes P ≤.001) between groups. However, statistical significance was lost once enucleation time was indexed against enucleated tissue weight. Time to achieve hemostasis (minutes) was statistically different between groups (10.6 + 6.1, 7.7 + 5.2, 6.3 + 4.8 P <.001). This difference in hemostatic time was maintained on multilogistic regression demonstrating that MOSES laser enucleation was associated with a 3.9-minute decrease time to achieve hemostasis after enucleation compared to Slimline 550 HoLEP (P <.001).

CONCLUSION

Our findings suggest that modulated pulsed laser energy can improve hemostasis during the enucleation phase of a HoLEP resulting in shorter Operating Room times.

Perioperative Safety in Patient Under Oral Anticoagulation During Holmium Laser Enucleation of the Prostate

INTRODUCTION AND OBJECTIVES

To evaluate the safety of holmium laser enucleation of the prostate (HoLEP) in patients on oral anticoagulation (OA) with respect to intra- and postoperative bleeding complications.

METHODS

Between January 2013 and October 2016, 2178 patients were included in this study, of whom 94 received direct oral anticoagulants (DOACs) and 151 received vitamin K antagonists (VKAs) before HoLEP. All patients either ceased OA (DOACs) or were bridged subtherapeutically (VKAs, international normalized ratio <2) during surgery. These patients were compared to a sample size of 1933 nonanticoagulated patients.

RESULTS

A significant longer postoperative stay was noted for the patients on DOACs (5.2 [4-6] days) and VKAs (5.3 [4-5] days) compared to the control group (4.5 [4-4] days). The mean drop in hemoglobin was significantly higher in the VKA group compared to the DOAC and control group. There was a significantly higher rate of postoperative bladder tamponades/secondary coagulation in patients on OA with 6 (7.9%)/3 (3.9%) patients in the DOAC group, 10 (7.4%)/6 (4.4%) patients in the VKA group compared to 37 (2.2%)/21 (2.1%) patients in the control group, respectively (p < 0.001). Eight patients required blood transfusions with a distribution of 1 (1.3%), 3 (2.2%), and 4 (0.2%) patients in the DOAC, VKA, and control group, respectively (p < 0.001).

CONCLUSIONS

Our findings indicate that bridged patients who's DOACs and VKAs were ceased before HoLEP are at higher risk of intra- and postoperative bleeding complications. Nonetheless, HoLEP appears to be a safe and effective procedure in those patients.

Best practice in the management of benign prostatic hyperplasia in the patients requiring anticoagulation

In today’s aging population, urologists are often treating older patients with multiple comorbidities. Lower urinary tract symptoms from benign prostate hyperplasia (LUTS/BPH) is a common condition that affects men, with increasing prevalence as men age. In a subset of patients, the symptoms are too severe or refractory to medical therapy and, therefore, surgical therapy is required to improve their LUTS. The use of medical therapy often delays the need to intervene surgically in men with LUTS/BPH and with advances in the management of cardiovascular disease, urologists are increasingly encountering more men requiring BPH surgery on chronic anticoagulation therapy. The decision of when to offer surgical intervention and how to manage anticoagulation medication in the perioperative setting is a dilemma with which surgeons are dealing with increasing frequency. The purpose of this review is to clarify the optimal approach to the surgical patient with LUTS/ BPH requiring anticoagulation therapy.
