Holmium Laser Enucleation of the Prostate Is Safe and Feasible as a Same Day Surgery

Trend of ambulatory benign prostatic obstruction surgeries during COVID-19 pandemic

INTRODUCTION

Benign prostatic obstruction (BPO) is one of the most common causes of male lower urinary tract symptoms. Some institutions routinely perform BPO surgeries in ambulatory setting, while others elect for overnight hospitalization. With the COVID-19 pandemic limiting resources and hospital space for elective surgery, we investigated the time trend of ambulatory BPO procedures performed around the COVID-19 outbreak.

METHODS

We identified BPO surgeries from the California State Inpatient and State Ambulatory Surgery Databases between 2018 and 2020. Our primary outcome was the proportion of procedures performed in ambulatory settings with a length of stay of zero days. Univariable and multivariable analyses were performed to analyze factors associated with ambulatory surgery around the COVID-19 outbreak. Spline regression with a knot at the pandemic outbreak was performed to compare time trends pre- and post-pandemic.

RESULTS

Among 37,148 patients who underwent BPO procedures, 30,067 (80.9%) were ambulatory. Before COVID-19, 80.1% BPO procedures were performed ambulatory, which increased to 83.4% after COVID-19 outbreak (p < 0.001). In multivariable model, BPO procedures performed after COVID-19 outbreak were 1.26 times more likely to be ambulatory (OR 1.26, 95% CI 1.14-1.40, p < 0.0001). Spline curve analysis indicated significantly different trend of change pre- and post-pandemic (p = 0.006).

CONCLUSIONS

We observed a rising trend of BPO surgeries performed in ambulatory setting post-pandemic. It remains to be seen if the observed ambulatory transition remains as we continue to recover from the pandemic.

Holmium laser enucleation of the prostate (HoLEP) in short-circuit outpatient care: Is prostatic volume a limiting factor?

INTRODUCTION AND OBJECTIVES

Our goals were to study prostatic volume as a limiting factor after HoLEP surgery with short-circuit outpatient care (4 h) and to define other factors that affect the success of the proposed circuit.

MATERIALS AND METHODS

An observational analysis and review was performed using a prospective database. Preoperative, intraoperative, and postoperative variables were included for patients who were scheduled for short-circuit outpatient care (SCOC) and who underwent HoLEP between 2020 and 2023. We defined SCOC as a postoperative hospital stay of 4 h. Subjects who required more than 4 h in hospital were categorized as conventional hospital admission (CHA). A descriptive populational study was conducted, expressing the mean using a 95% confidence interval and percentages for the continuous variables. In order to analyze them, we used the Student's t-test for the continuous variables and the chi-squared test for the categorical variables.

RESULTS

Sixty-eight patients were included, 54 of which completed SCOC, which represented a success ratio of 79.5%. The mean age and prostatic volume of the whole cohort were 68.9 (±6.8) years and 79.5 (±29.1) mL, respectively. We found no significant differences in age, prostatic volume, antiplatelet drug use, indwelling bladder catheter, or applied energy among the subjects who completed SCOC and those who required CHA. No patient was presented with a complication of Grade 3 (or higher) in the modified Clavien-Dindo classification. At the six-month follow-up, no differences were observed in the uroflowmetry or International Prostate Symptoms Score variables.

CONCLUSIONS

Prostatic volume does not seem to be a limiting factor after undergoing HoLEP with short-circuit outpatient care.

Same-day catheter removal after holmium laser enucleation of the prostate (HoLEP): a systematic review

PURPOSE

To summarize all existing evidence regarding the feasibility, safety, and efficacy of same-day trial of void and catheter removal after Holmium Laser Enucleation of the Prostate (HoLEP). Although there have been many reports of the safety and efficacy of same-day discharge from the hospital for selected patients undergoing HoLEP, in most of these reports, patients return to the hospital, usually on postoperative day one, to undergo a trial of void and catheter removal.

METHODS

PubMed®, Scopus®, and Cochrane® primary databases were systematically screened, from inception to 17 January 2023. The search strategy used the PICO (Patient, Intervention, Comparison, Outcomes) Framework. We followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.

RESULTS

Six studies met all the predefined criteria and were included in the final qualitative synthesis. Four studies were retrospective and two were prospective. Four studies were non-comparative, while two were comparative ones. The same-day catheter removal success rate ranged from 85.5 to 90% among studies, while only one grade-IIIb Clavien-Dindo complication was reported, which was unrelated to surgery.

CONCLUSION

Same-day catheter removal is a feasible, safe, and efficient approach for selected patients undergoing HoLEP. Certain factors, such as intraoperative furosemide administration, were found to improve same-day catheter-free rates, while preoperative PVR and urinary retention were independent predictive factors of same-day trial of void failure.

Is day-case surgery feasible for laser endoscopic enucleation of the prostate? A systematic review

PURPOSE

Laser endoscopic enucleation of the prostate (EEP) for benign prostatic obstruction has become increasingly prevalent worldwide. Considering the medical cost-savings and concomitantly fewer nosocomial infections, the feasibility of same-day postoperative discharge of patients who have undergone laser EEP in terms of its safety and effectiveness has become a subject matter of growing interest. We aimed to review those studies focussing on day-case surgery (DCS) in patients undergoing laser EEP.

METHODS

A systematic search was conducted using PubMed-MEDLINE and Web of Science databases until October 2022 with the following search terms: "same day discharge AND laser enucleation of the prostate", "day-case AND laser enucleation of the prostate", "same day surgery AND laser enucleation of the prostate" and "one day surgery AND laser enucleation of the prostate" by combining PICO (population, intervention, comparison, outcome) terms. We identified 15 eligible studies.

RESULTS

While 14 of the studies focussed on holmium laser EEP, one focused on thulium laser vapoenucleation of the prostate. We observed an improvement in functional parameters in all studies we reviewed, and DCS success and readmission rates ranged between 35.3-100% and 0-17.8%, respectively. The complication rates varied between 0 and 36.7%, most of the complicatons were Clavien-Dindo (CD) I and II. CD ≥ III complications did not significantly differ between same day discharge (SDD) and non-SDD groups in the studies.

CONCLUSION

Laser EEP is feasible and promising DCS treatment option delivering improved functional parameters compared to baseline values, and lower perioperative complication and readmission rates in certain patients.

Tranexamic Acid Was Not Associated With a Reduction in Bleeding Complications Related to Holmium Laser Enucleation of the Prostate

OBJECTIVE

To compare outcomes in males given perioperative tranexamic acid (TXA) during holmium laser enucleation of the prostate (HoLEP) to a historical cohort that did not receive TXA.

METHODS

Our cohort included HoLEP patients (N = 1037) from August 2018 through November 2022. Exclusion criteria included history of stroke, transient ischemic attack, or coronary stent placed within 18 months. The primary predictor was TXA during HoLEP. The primary outcome variable was a return to the operating room (RTOR) for bleeding. Secondary outcomes included catheter reinsertion, transfusion, and clotting complications. Multivariable models evaluating associations of TXA with outcomes were adjusted for potential confounders.

RESULTS

In our cohort, 214/1035 had one or more complications with 81 having a Clavien-Dindo Grade of 3a or higher, 114/1037 with catheter reinsertion, 36/1037 RTOR for bleeding, and 15/1035 had a transfusion. TXA use was not associated with 30-day RTOR. 3.7% of those without TXA had a RTOR, and 3.1% of those with TXA had a RTOR (adjusted odds ratio 0.63, 95% CI 0.28-1.38, P = .25). Transfusion rates were higher for those without TXA (2.0%) compared to with (0.5%). This was statistically significant after adjustment (adjusted odds ratio 0.13, 95% CI 0.03-0.69, P = .016) and after correction for multiple testing (corrected P = .048). TXA use was not associated with catheter reinsertion or clotting complications.

CONCLUSION

Routine perioperative intravenous TXA in HoLEP patients was not associated with a reduction of RTOR for bleeding, catheter reinsertion, or clotting complications. TXA was associated with decreased transfusions with a low overall event rate of 1.4%.

Holmium laser enucleation of the prostate (HoLEP) as same-day surgery: A safe and feasible option

OBJECTIVE

To study the feasibility of holmium laser enucleation (HoLEP) performed as a same-day surgery.

MATERIAL AND METHODS

Prospective observational study including 25 patients submitted to HoLEP. Patients were discharged the same day if they met the established criteria.

RESULTS

The mean age of the patients was 65.1 years and prostate volume was 45.8cc. All patients were discharged the same day of surgery. The overall complication rate at 30 days was 12% (Clavien I 100%). The rate of re-hospitalization was 0%. Patient satisfaction rate with the day surgery pathway was 95%.

CONCLUSIONS

The initial analysis of our results suggests that outpatient HoLEP is a safe and effective alternative with low rate of complications. According to satisfaction rates, patients prefer the day surgery pathway for the performance of HoLEP.

Robotic assisted simple prostatectomy versus other treatment modalities for large benign prostatic hyperplasia: a systematic review and meta-analysis of over 6500 cases

BACKGROUND

Current guidelines recommend simple prostatectomy or endoscopic enucleation of the prostate (EEP) as treatment of choice for bladder prostatic obstruction (BPO) caused by large prostate glands. We aimed to provide a wide-ranging analysis of the currently available evidence, comparing safety and effectiveness of robot-assisted simple prostatectomy (RASP) versus open simple prostatectomy (OSP), laparoscopic simple prostatectomy (LSP), and laser EEP.

METHODS

A systematic search was performed across MEDLINE, EMBASE, and Web of Science databases for retrospective and prospective studies comparing RASP to OSP or LSP or laser EEP (HoLEP/ThuLEP). Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) recommendations were followed to design the search strategies, selection criteria, and evidence report. A meta-analysis evaluated perioperative safety and effectiveness outcomes. The weighted mean difference and risk ratio were used to compare continuous and dichotomous variables, respectively. Quality was assessed using the Newcastle-Ottawa scale and the Cochrane Collaboration's tool for RCT article assessing risk of bias.

RESULTS

15 studies, including 6659 patients, were selected for meta-analysis: 13 observational studies, 1 non-randomized prospective study, and 1 randomized controlled trial. RASP was associated with statistically significant longer operative time (OT) and lower postoperative complication rate, length of stay (LOS), estimated blood loss (EBL), and transfusion rate (TR) compared to OSP. LSP showed longer LOS and lower postoperative SHIM score, with no difference in OT, EBL, and complications. Compared to laser EEP, RASP presented longer LOS and catheterization time and higher TR. ThuLEP presented shorter OT than RASP. No difference were found in functional outcomes between groups both subjectively (IPSS, QoL) and objectively (Qmax, PVR).

CONCLUSION

RASP has become a size-independent treatment for the management of BPO caused by a large prostate gland. It can duplicate the functional outcomes of OSP while offering a better safety profile. When compared to LSP, the latter still stands as a valid lower-cost option, but it requires solid laparoscopic skill sets and therefore it is unlikely to spread on larger scale. When compared to laser EEP, RASP offers a shorter learning curve, but it still suffers from longer catheterization time and LOS.

Same-day discharge for endoscopic enucleation of the prostate: a systematic review and meta-analysis

PURPOSE

To systematically review studies focused on the feasibility and outcomes of outpatient endoscopic enucleation of the prostate for benign prostatic obstruction.

METHODS

A literature search was conducted through December 2022 using PubMed/Medline, Web of Science, and Embase databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. Risk of bias assessment was performed according to the Newcastle-Ottawa Scale for case control studies.

RESULTS

Of 773 studies, ten were included in the systematic review (n = 1942 patients) and four in the meta-analysis (n = 1228 patients). The pooled incidence of successful same-day discharge was 84% (95% CI 0.72-0.91). Unplanned readmission was recorded in 3% (95% CI 0.02-0.06) of ambulatory cases. In the reported criteria-selected patients submitted to SDD surgery, the forest plot suggested a lower rate of postoperative readmission (OR 0.56, 95% CI 0.34-0.91, p = 0.02) and complications (OR 0.69, 95% CI 0.48-1, p < 0.05) rates compared to standard protocols.

CONCLUSION

We provide the first systematic review and meta-analysis on SDD for endoscopic prostate enucleation. Despite the lack of randomized controlled trials, we confirm the feasibility and safety of the protocol with no increase in complications or readmission rate in well-selected patients.

The outcomes of same-day discharge following holmium laser enucleation of the prostate (HoLEP) surgeries: our experience during the COVID-19 pandemic

OBJECTIVE

To describe the outcomes of Same-Day Discharge (SDD) following Holmium Laser Enucleation of the Prostate (HoLEP) in patients during the COVID-19 pandemic.

METHODS

A retrospective review of HoLEP surgeries at a single institution between January 2021 and March 2022 was performed. Patient demographic and operative data were collected, and postoperative outcomes were evaluated in terms of safety and efficacy and compared in both groups using a t-test and chi-square test. Logistic regression was also performed to identify factors that correlate with the failure of SDD.

RESULTS

A total of 155 patients were identified; 135 patients were successfully discharged on the same day and 20 were admitted (87% SDD rate). Admitted HoLEP patients had a significantly higher median prostate-specific antigen (5.7 vs 3.9 ng/dL, P < 0.001), prostate volume (152.3 vs 100.6 mL, P < 0.001), and enucleated tissue weight (90.3 vs 56.9 g, P = 0.04) compared to the SDD group. The SDD group had a 2.9% (n = 4) readmission rate and a 5.2% (n = 7) Emergency Department (ED) visit rate. There was no significant difference in the rate of postoperative ED visits (P = 0.64), readmissions (P = 0.98), complications, and catheterization time (P = 0.98) between both groups. Preoperative predictors of SDD failure included prostate gland volume > 150 mL (OR = 7.17; CI 2.01-25.67; P < 0.01) and history of antiplatelet/anticoagulation use (OR = 6.59; CI 2.00-21.67; P < 0.01).

CONCLUSION

Same-day discharge following HoLEP is a safe and effective approach that can be performed in most patients using a liberal discharge criteria and relying on postoperative findings only.

Ultrasound-guided perineal laser ablation versus prostatic arterial embolization for benign prostatic hyperplasia: two similar short-term efficacies

BACKGROUND

There are many ways to treat prostatic hyperplasia; these are currently more inclined to minimally invasive treatment. We mainly compared the differences between two treatment methods， ultrasound-guided transperineal laser ablation (US-TPLA) and prostatic artery embolization (PAE).

PURPOSE

To evaluate the efficacy and safety of US-TPLA and PAE in the treatment of benign prostatic hyperplasia (BPH).

MATERIAL AND METHODS

The clinical information for 40 patients with BPH admitted to our hospital between June 2018 and January 2021 were retrospectively analyzed. The changes in International Prostate Symptom Score (IPSS), quality of life (QoL), maximum urinary flow rate (Qmax), postvoid residual (PVR), prostate volume (PV), and the incidence of complications were compared between groups.

RESULTS

The IPSS (P < 0.001; P < 0.001), QoL (P < 0.001; P < 0.001), Qmax (P < 0.001; P < 0.001), PVR (P < 0.001; P < 0.001), and PV (P < 0.001; P < 0.001) at three and six months after US-TPLA and PAE improved with respect to those before surgery. There was no significant difference in IPSS (P = 0.235; P = 0.151), QoL (P = 0.527; P = 0.294), Qmax (P = 0.776; P = 0.420), PVR (P = 0.745; P = 0.607), and PV (P = 0.527; P = 0.573) between the groups at three and six months after surgery. No serious complications occurred in either group.

CONCLUSION

US-TPLA and PAE seem to have a similar short-term efficacy. The efficacy of the two procedures is comparable, and neither is associated with serious complications. US-TPLA and PAE are both effective complementary measures for the treatment of BPH.

Predictors of readmission and impact of same-day discharge in holmium laser enucleation of the prostate

Background

Holmium enucleation of the prostate (HoLEP) is becoming the gold standard for the treatment of benign prostatic hyperplasia (BPH). Our objective was to identify predictors of 30-day readmission and the impact of same-day discharge after HoLEP.

Methods

Using NSQIP data from 2011 to 2019, we identified men who underwent HoLEP for the treatment of BPH. We compared patients based on time of discharge and readmission status. We used multivariable logistic regression analysis (MLRA) to identify independent factors associated with 30-day readmission.

Results

A total of 3,489 patients met inclusion criteria with 833 (23.88%) being discharged within 24 hours and 2,656 (76.12%) discharged after 24 hours. There were 158 (4.53%) 30-day readmissions, mostly due to hematuria and urinary tract infection. Patients being readmitted were older (72 vs. 70 years old, P = 0.001), were more likely to have preoperative anemia (36.7% vs. 23.1%; P < 0.001), chronic kidney disease (29.7% vs. 19.7%; P < 0.001), bleeding disorder (10.8% vs. 2.8%; P < 0.001), higher American Society of Anesthesiologists (ASA) scores (≥3: 70.3% vs. 46.7%; P < 0.001) and a higher frailty burden (5-item modified frailty index [5i-mFI] ≥ 2: 36.1% vs. 19.1%; P < 0.001) compared to their counterparts. Factors independently associated with 30-day readmission were bleeding disorder (OR 2.89; 95% CI 1.63-5.11; P < 0.001), 5i-mFI ≥ 2 (OR 1.67; 95% CI 1.03-2.71; P = 0.038) and an ASA score ≥3 (OR 1.80; 95% CI 1.21-2.70; P = 0.004); however, same-day discharge was not found to be a significant predictor of 30-day readmissions.

Conclusion

The overall readmission rate after HoLEP is low. Patients discharged within 24 hours have similar rates of readmission compared to patients discharged after 24 hours. We found bleeding disorder, frailty burden, and ASA score to be independent predictors of 30-day readmission.

No bladder irrigation versus continuous bladder irrigation after HoLEP: a propensity score matching analysis

PURPOSE

In this study, the feasibility of a no bladder irrigation strategy after transurethral holmium laser enucleation of the prostate (HoLEP) for the treatment of benign prostatic hyperplasia (BPH) was studied.

METHODS

From August 2021 to December 2021, the clinical data of 62 patients who received no bladder irrigation after HoLEP (Group A) were studied. The control group contained the clinical data of 150 patients in the same therapy group (from January 2021 to July 2021) who received continuous bladder irrigation after HoLEP (Group B). The baseline was consistent after using the propensity score matching (PSM) method, and the differences between groups were compared. The pre- and postoperative complications, international prostate symptom score (IPSS), quality of life (QOL), maximum urinary flow rate (Qmax), and postvoid residual urine (PVR) of the two groups were compared, accompanied by a follow-up evaluation of surgical effects.

RESULTS

47 pairs of patients were successfully matched by PSM. There was no statistically significant difference in the intraoperative conditions and the incidence of early postoperative complications between the two groups (P > 0.05). Before and one month after the surgery, significant differences were also found in the IPSS, QOL, Qmax, and PVR of both groups (P < 0.05). Within one month after the surgery, no statistically significant difference was found in IPSS, QOL, Qmax, PVR, or the incidence of early postoperative complications between the two groups (P > 0.05).

CONCLUSION

For appropriately selected patients according to the exclusion criteria, the no bladder irrigation strategy after HoLEP for BPH is safe and effective.

Comparison of Contemporary Surgical Outcomes Between Holmium Laser Enucleation of the Prostate and Robotic-Assisted Simple Prostatectomy

PURPOSE OF REVIEW

This study reviews contemporary literature on RASP and HoLEP to evaluate perioperative outcomes, common complications, cost analytics, and future directions of both procedures.

RECENT FINDINGS

RASP is indicated for prostates > 80 mL, while HoLEP is size-independent. No notable differences were found in operative time, PSA nadir (surrogate for enucleation volume), re-catheterization rates, or long-term durability. Prolonged incontinence and bladder neck contracture rates are low for both surgeries. Patients experience similar satisfaction outcomes and improvements in uroflowmetry and post-void residual volumes. HoLEP demonstrates shorter hospitalizations, lower transfusion rates, lower costs, and higher rates of same-day discharge. RASP offers a shorter learning curve and lower rates of early postoperative urinary incontinence. HoLEP is a size-independent surgery that offers advantages for patients seeking a minimally invasive procedure with the potential for catheter-free same-day discharge. Future directions with single-port simple prostatectomy may offer parity in same-day discharge, but further research is needed to determine broader feasibility.

Tranexamic Acid Does Not Improve Outcomes of Holmium Laser Enucleation of the Prostate: A Prospective Randomized Controlled Trial

Introduction: Tranexamic acid (TXA) is a clot promoting agent utilized during orthopedic procedures to decrease bleeding. Urologists have demonstrated the benefits of TXA in percutaneous surgery. Our objective was to assess the safety and efficacy of single-dose TXA on same-day holmium laser enucleation of the prostate (HoLEP) outcomes. Methods: From September 2021 to January 2022, we prospectively randomized 110 patients undergoing HoLEP to either 1 g of TXA after induction or no treatment. Institutional Review Board (IRB) approval (STU00215134) and registry with ClinicalTrials.gov (NCT05082142) were obtained before enrollment. Primary outcome was the rate of effective same-day discharge (SDD). Secondary outcomes included transfusion rate, same-day catheter removal, length of stay (LOS), and 90-day complications. Power analysis determined that 110 patients should be enrolled to detect a 25% difference in SDD rate. Results: There was no difference in patient demographic and prostate features between the control (n = 55) and TXA groups (n = 55; all p > 0.05). The overall rate of effective SDD was not different between the control and TXA groups (49/55 [89%] vs 51/55 [93%], p = 0.74). Median LOS (hh:mm) was not different between groups (03:07 vs 02:50, p = 0.23) with only 3/110 (2.7%) having an LOS >24 hours. Effective same-day catheter removal occurred in 99/110 (90%) patients with no difference between groups (49/55 vs 50/55, p = 0.99). There was no difference in operative parameters (time, energy, specimen weight) and postoperative complications between groups (all p > 0.05). No patients required transfusions and there were no major 90-day complications related to surgery (Clavien-Dindo ≥IIIb). Conclusion: TXA administration is safe but did not impact SDD after HoLEP.

Analysis of Holmium Laser Enucleation of Prostate Fixed Operating Room Times

OBJECTIVE

To evaluate factors influencing fixed operating room time during holmium laser enucleation of the prostate.

MATERIALS AND METHODS

A prospective observational study was performed for all holmium laser enucleation of the prostate (HoLEP) cases performed by a single surgeon over a 24-month period. Operating room (OR) time was divided into fixed and variable time. The variable time was defined as cut-to-close time. Fixed time included in room time to anesthesia release time (IRAT), anesthesia release time to cut time (ARCT), and close time to wheels out (CTWO). The effects of time of day and anesthesia personnel (AP) changes on fixed operating room time were evaluated.

RESULTS

A total of 406 HoLEPs were analyzed. There was no statistically significant difference in nonprocedural OR times between morning and afternoon surgeries (IRAT, P=0.38, ARCT P=0.10, CTWO P=0.77). Median nonprocedural OR times accounted for 27% (IQR: 22%-31%) of the total procedure time in the AM group and 29% (IQR: 24%-33%) in the PM group (P=0.005). Of the HoLEPs,78.1% (178/228) experienced one or more AP changes during the procedure. The median fixed OR time was not significantly different between procedures with 1 AP and procedures with ≥2 APs (IRAT, P=0.53; ARCT, P=0.71; CTWO, P=0.98).

CONCLUSIONS

Fixed operating room time makes up a significant portion of HoLEP procedures and should be considered when evaluating OR efficiency. The time of day and number of anesthesia personnel involved did not affect the fixed OR times.

Holmium: yttrium-aluminum-garnet laser with Moses: does it make a difference?

PURPOSE OF REVIEW

Moses effect is an inherent physical principle of Ho:YAG laser functioning. Moses Technology is a pulse modulation modality of Ho:YAG laser, which became commercially available for the treatment of two urological conditions: urinary stones and benign prostatic obstruction. The purpose of this narrative review is to distinguish between Moses effect and Moses Technology, as well as to summarize the latest evidence on Moses Technology and its main application in the urological field.

RECENT FINDINGS

During laboratory lithotripsy, Moses Technology seems to reduce stone retropulsion and determine higher ablation volume compared with regular lithotripsy. However, this technology presents similar characteristics to long pulse Ho:YAG laser, and several studies showed no significant difference between Moses Technology and standard lasers. When used in prostate enucleation, Moses Technology promises to reduce operating time by increasing the efficiency of prostate resection and improve the hemostasis. Moreover, some studies state that it is possible to reduce the HoLEP morbidity. Despite this, the clinical impact of the time reduction remains uncertain and different studies either present relevant limitations or are burdened by significant bias.

SUMMARY

Although Moses effect has been extensively described and characterized, and several studies have been published on the usage of Moses Technology for both laser lithotripsy and laser enucleation of the prostate with Holmium YAG, solid clinical evidence on the real improvement of surgical outcomes is still missing.

Expanded Criteria Same Day Catheter Removal Following Holmium Laser Enucleation of the Prostate (HoLEP)

Introduction and Objectives Holmium laser enucleation of the prostate (HoLEP) is a highly effective treatment of benign prostatic hyperplasia (BPH). Technical advances and improved hemostatic properties of Holmium lasers have allowed for increased efficiency and outcomes. Same day catheter removal following HoLEP was described at our institution in 2020 following a 30-patient pilot trial. We now present an expanded update following widespread adoption at our facility. Methods We reviewed patients who underwent same day catheter removal after HoLEP between 1/1/2020 and 3/21/2021. Unlike previous trials, there were no limitations to prostate size. Other changes included catheter removal in phase two of recovery when nursing was available rather than the urology clinic. Descriptive statistics are presented of preoperative, operative, and postoperative data. Univariate and multivariate analysis was performed to assess associations with failure of same day void trial. Results The success rate of same-day catheter removal for the 114 identified patients was 87.7%. Mean age was 69.1  8.6 years and prostate volume was 109.2  61.5cc, 35% were dependent on catheterization for urinary retention preoperatively and 9% were on antiplatelet/anticoagulant therapy. A total of 26.5% of patients with ASA 3 or 4 failed catheter removal compared to 3.9% of patients with ASA 1 or 2 (Likelihood ratio 9.32, p=0.002), ASA status lost significance on multivariate analysis (p=0.076). Successful catheter removal was not significantly associated with age, BMI, prostate size, catheter dependency, anticoagulation/antiplatelet therapy, AUA symptom score, prior BPH surgery, or prostate cancer in final pathology. Conclusion Regardless of prostate size, same day catheter removal is a safe and reliable method of post-HoLEP patient management. Patients with an ASA 3 or 4 should be counseled regarding potential risks of temporary re-catheterization. Given ongoing nationwide shortages in hospital beds and staffing, same day discharge and catheter removal may allow for wider availability of surgical treatment for BPH.

Robot assisted simple prostatectomy versus endoscopic enucleation of the prostate: A systematic review and meta-analysis of comparative trials

Robot assisted simple prostatectomy (RASP) and endoscopic enucleation of the prostate (EEP) are two minimally invasive alternatives to simple prostatectomy, which is considered the standard treatment in large prostate glands. It remains unclear which of the two is superior in terms of outcome and complications. To compare perioperative and functional outcomes of robot assisted simple prostatectomy (RASP) versus endoscopic enucleation of the prostate (EEP) systematic review and meta-analysis was conducted according to the recommendations of the Cochrane Collaboration and in line with the PRISMA criteria. The database search included clinicaltrials.gov, Medline (via PubMed), CINAHL and Web of Science and was using the PICO criteria. All comparative trials were considered. Risk of bias was assessed with the revised ROBINS-I tool. 760 studies were identified, four of which were eligible for qualitative and quantitative analysis, reporting on a total of 901 patients with follow-up up to 24 months. Hemoglobin drop (MD[CI]: 0.34 g/dl [0.09; 0.58]), the rate of blood transfusions (OR[CI]: 5.01 [1.60; 15.61]) catheterization time (MD[CI]: 3.26 d [1.30; 5.23]) and length of hospital stay (LoS) (MD[CI]: 1.94 d [1.11; 2.76]) were significantly lower in EEP. No significant differences were seen in operating time and enucleation weight. No significant differences were observed in the incidence of postoperative urinary retention, postoperative transient incontinence and complications graded according to the Clavien-Dindo Classification. Functional results were similar, with no significant differences in International Prostate Symptom Score and maximum urinary flow rate at follow-up. Conclusion: Both EEP and RASP offer excellent improvement of symptoms due to prostatic hyperplasia. EEP has lower blood loss, shorter catheterization time and LoS and should be the first choice if available. RASP remains an attractive alternative for extremely large glands, in concomitant diseases or whenever EEP is not available.

Surgical treatment options for benign prostatic obstruction: beyond prostate volume

PURPOSE OF REVIEW

Many surgical treatment options are available for patients who present with benign prostatic obstruction (BPO). This article reviews the current treatment options available and distinguishes them based on five clinical considerations: antithrombotic therapy, sexual function preservation, ambulatory procedures, anesthesia-related risks and duration of catheterization.

RECENT FINDINGS

A comprehensive review of the literature was performed on 10 BPO procedures. Laser enucleation of the prostate (LEP), bipolar plasma transurethral vaporization of the prostate and photoselective vaporization (PVP) of the prostate reduces the risk of bleeding, which is recommended for anticoagulated men. Ejaculatory function is more likely to be preserved following transurethral incision of the prostate, Rezūm, Aquablation, UroLift and iTind. Same-day discharge is possible for LEP, PVP and prostatic arterial embolization (PAE). For patients with high anesthesia-related risks, procedures compatible with local anesthesia (UroLift, Rezūm, iTind and PAE) should be favored. Catheterization duration is shorter with UroLift, PVP and LEP.

SUMMARY

BPO treatment options are growing rapidly. The optimal procedure for a given patient is based on factors such as associated risks, recovery and expected outcomes. Besides prostate volume, the clinical considerations in the present article can help elucidate the best surgical BPO treatment option for each patient based on their values, preferences, and risk tolerance.

Barriers to Implementation of a Same-Day Discharge Pathway for Holmium Laser Enucleation of the Prostate

OBJECTIVE

To investigate perceived barriers to successful same-day discharge (SDD) after holmium laser enucleation of the prostate (HoLEP) from the perspective of surgical and nursing staff members.

METHODS

A 17-question survey was administered to intraoperative and postoperative surgical staff in June 2021 after a six-month period of implementing a SDD HoLEP pathway with same-day catheter removal. McNemar's and Stuart-Maxwell tests were performed for statistical analysis.

RESULTS

Surveys were completed by 30 respondents. The majority of respondents had less than 5 years of surgical experience (63%). Almost all respondents (96%) felt that HoLEP patients could be discharged safely on day of surgery. Overall, 60% felt that HoLEP had a lower risk of post-operative bleeding compared to other transurethral surgeries. There was a significant decrease in number of respondents that felt apprehensive when comparing initiation of SDD HoLEP pathway to 6-months post-implementation (43% vs 7%, P = .003). The most common factors causing apprehension both pre- and post-implementation included: degree of hematuria (43% vs 40%, P = .56), risk of failure of trial of void (40% vs 30%, P = .26), and risk of readmission or unplanned emergency department (ED) visit (33% vs 30%, P = .48). There was a significant decrease in the number of respondents who were apprehensive about lack of experience with SDD after HoLEP comparing pre- and post-implementation (20% vs 0%, P = .01).

CONCLUSION

While staff report initial apprehension regarding implementation of a SDD HoLEP pathway, adequate support to intraoperative and postoperative teams helps build experience that alleviates these concerns.

Electrosurgery or laser for benign prostatic enlargement: trumpcard or pitfalls

PURPOSE OF REVIEW

To summarize and comment on publications of the last 2 years in the field of endoscopic surgery for benign prostatic enlargement, focusing on similarities and differences of laser and electrosurgery.

RECENT FINDINGS

Because of good hemostasis and safety, invasive endoscopic surgery has evolved to a choice of treatment for vulnerable patients with ongoing antithrombotic medication and in same-day surgery. Recent publications show a good perioperative course and no deterioration in the postoperative outcome. Furthermore, alterations to the original surgical techniques of resection, enucleation, and vaporization have increased the preservation rate for antegrade ejaculation, advancing them to an appealing choice of treatment for sexually active men. Favorable outcomes can be achieved in both laser and electrosurgery. Only the choice of the surgical technique determines the outcome.

SUMMARY

Various invasive endoscopic surgical techniques are available, offering different advantages and disadvantages for the patient. All of them can be performed with laser and electrosurgery. Therefore, focusing on the proper choice of surgical technique instead of the energy source will guarantee the patient to benefit most.

Spinal versus general anesthesia for Holmium laser enucleation of the prostate of high-risk patients - A propensity-score-matched-analysis

OBJECTIVE

To compare perioperative management and functional outcome of spinal anesthesia (SpA) to general anesthesia (GA) in high-risk patients treated for lower urinary tract symptoms (LUTS) with Holmium laser enucleation of the prostate (HoLEP).

METHODS

In the current retrospective analysis, a propensity-score-matching of patients treated for LUTS with HoLEP (n=300) in SpA with ASA>2 (n=100), GA with ASA>2 (GA-high-risk) (n=100) or GA with ASA≤2 (GA-low-risk) (n=100) was performed. The impact of anesthesiologic mode on perioperative anesthesiologic outcome, early functional outcome and treatment related adverse events (according to Clavien Dindo), was evaluated.

RESULTS

Hypotensive episodes were significantly less frequent in the SpA-cohort (9%) compared to the GA-high-risk cohort (32%) and the GA low-risk cohort (22%) (each p<0.05 respectively). SpA-patients showed a significantly shorter median time in post anesthesia care unit (PACU-time: 135min; 120-166.5) compared to GA-high-risk patients (186min; 154-189.5), with significant less referrals to Intermediate care unit (ICU) (1% vs. 9 %); (each p<0.05). PACU-time (99min) and ICU referrals (0%) for GA-low-risk were lower than for both other cohorts. Postoperative requirement for analgesics was significantly lower in the SpA-cohort (2%), compared to both GA-cohorts (74% and 61% respectively; p<0.05). No significant difference was found regarding early functional outcome or treatment related adverse events (AE) (p-range:0.201-1.000).

CONCLUSION

For patients undergoing HoLEP, SpA provides greater hemodynamic stability and allows faster overall postoperative recovery with preferable pain management. Yielding a comparable functional outcome, it is a safe and efficient alternative to GA in high-risk patients.

Comparison of Newly-Optimized Moses Technology Versus Standard Holmium:YAG for Endoscopic Laser Enucleation of the Prostate

INTRODUCTION

The purpose of this study was to describe our initial experience of using a newly-optimized Moses technology that is part of the second generation Moses platform specifically designed for holmium laser enucleation of the prostate M2-HoLEP, and compare it to patients undergoing holmium laser enucleation of the prostate (HoLEP) using standard holmium:YAG technology (S-HoLEP).

METHODS

We retrospectively collected data on patients who underwent M2-HoLEP and compared it to the last 50 patients in whom we performed S-HoLEP. Specifically, we compared preoperative symptom scores for lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), preoperative objective voiding metrics, as well as intraoperative characteristics, perioperative characteristics, postoperative complications, postoperative symptom scores for LUTS and ED, and postoperative objective voiding metrics. Additionally we evaluated the ability for same day discharge following surgery in the M2-HoLEP group.

RESULTS

We included 104 total patients for analysis. We compared the first 54 patients undergoing M2-HoLEP to 50 patients undergoing S-HoLEP. Both groups had similar age, BMI, use of anticoagulation medication, LUTS and ED scores, and objective voiding metrics. Operations performed with M2-HoLEP had faster mean hemostasis time (8.7 vs 10.6 ± 6 minutes, p=0.03) as well as hemostasis rate (0.13 vs 0.30 grams/minute, p=0.01). Same day discharge was successful in 69.4% of patients in the M2-HoLEP group. Postoperatively, both groups also had similar and low rates of urinary retention and complications. At follow-up, both groups had similar symptom scores for LUTS and ED, as well as similar objective voiding metrics.

CONCLUSION

The newly optimized Moses pulse modulation technology is safe and efficient for the treatment of BPH. Such technologic improvements in the laser have greatly enhanced the feasibility of same day discharge of patients undergoing HoLEP.

Same-Day Discharge Following Holmium Laser Enucleation in Patients Assessed to Have Large Gland Prostates (≥175 cc)

Background: Holmium laser enucleation of the prostate (HoLEP) is a highly effective and durable minimally invasive surgery for benign prostatic hyperplasia. Historically, alternative treatments for large glands (≥175 cc) are associated with prolonged length of stay (LOS) and postoperative catheterization. However, advances in laser technology combined with surgical technique optimization have early evidence supporting same-day discharge. We look to examine contemporary same-day discharge outcomes for large glands. Materials and Methods: With Institutional Review Board (IRB) approval we queried our electronic medical record and retrospective clinical registry to examine perioperative outcomes of large gland (≥175 cc) prostates that underwent HoLEP with consideration for same-day discharge. Results: From December 10, 2019 to September 29, 2020 we identified 55 patients with a preoperative prostate size ≥175 cc (39 CT, 12 MRI, 4 transrectal ultrasound), of which 45 were scheduled for same-day discharge and 10 for admission. Mean preoperative prostate size was 229.9 cc (range 175-535 cc) and 36 (65.5%) were in urinary retention. Mean preoperative prostate-specific antigen (PSA) was 8.58 ng/mL, American Urological Association Symptom Score (AUASS) 22.3, and Qmax 8.8 mL/second. At 3 months postoperative follow-up mean AUASS was 6.7, PSA 0.87 ng/mL and Qmax 20.4 mL/second. All comer same-day discharge rate was 70% (38/55). Of patients planned for same-day discharge 38/45 (84%) were effective. Average LOS for all patients was 11.8 hours with catheterization of 21.2 hours. When compared with 2010 published large gland outcomes, our current LOS represents a 220% reduction. Looking specifically at patients planned for same-day discharge, average LOS and catheter duration was 8.8 and 17.0 hours, whereas LOS and catheter duration for patients planned for admission was 25.7 and 39.4 hours, respectively. Conclusions: We report the first outcomes of preoperatively planned same-day discharge for HoLEP in large glands (≥175 cc). A combination of technologic advances and optimization of technique have allowed for a safe adoption of same-day discharge, providing additional advantages over alternative large gland treatments.

Safety and Feasibility of Outpatient Surgery in Benign Prostatic Hyperplasia: a Systematic Review and Meta-Analysis

Purpose: Most of the endourologic procedures along the urinary tract have been widely practiced as outpatient operations, including surgery for benign prostatic hyperplasia (BPH). This systematic review and meta-analysis was conducted to assess safety and feasibility of outpatient surgery for patients suffering from symptomatic BPH candidate for endoscopic disobstruction. Materials and Methods: PubMed, Web of Science, Cochrane, and Embase were searched up until March 30, 2020. Methodological index for nonrandomized studies (MINORS) tool was utilized to assess the quality of included studies, and a pooled measure of failure rate (FR) or event rate (ER) estimate was calculated. Further sensitivity analysis, subgroup analysis, and meta-regression were conducted to investigate contribution of moderators to heterogeneity. Results: Twenty studies with a total of 1626 patients treated according to outpatient criteria for endoscopic BPH surgery were included. In total, 18 studies reporting data on immediate hospital readmission and/or inability to discharge after endoscopic procedure presented FR estimates ranging from 1.7% to 51.1%. Pooled FR estimate was 7.8% (95% confidence interval [CI]: 5.2-10.3); Heterogeneity: Q = 76.85; degree of freedom = 17, p < 0.001; I² = 75.12%. Subgroup analysis according to surgical technique revealed difference among the three approaches with pooled FR of 3% (95% CI: 1-4.9), 7.1% (95% CI: 3.9-10.4), and 11.8% (95% CI: 7-16.7) for transurethral resection of the prostate, Green-light, and holmium laser vaporesection, respectively (p < 0.001). At meta-regression analysis, none of the retrieved covariates was able to significantly influence the cumulative outcomes reported. ER for postoperative complications and early outpatient visit showed a pooled estimate of 18.6% (95% CI: 13.2-23.9) and 7.7% (95% CI: 4.3-11), respectively. Conclusions: Our analysis revealed how transurethral procedures for BPH on an outpatient setting are overall reliable and safe. Of note, there were significant outcome differences between groups with regard to type of surgical procedure, perioperative prostate volume, and discharge protocol suggesting the need for further prospective analysis to better elucidate the best strategy in such outpatient conduct.

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.

Perioperative outcomes and cost of robotic vs open simple prostatectomy in the modern robotic era: results from the National Inpatient Sample

OBJECTIVES

To perform a comparative analysis of perioperative outcomes and hospitalisation cost between open (OSP) and robot-assisted simple prostatectomy (RASP) for treatment of benign prostatic hyperplasia (BPH) using the National Inpatient Sample (NIS) in the contemporary robotic era.

MATERIALS AND METHODS

The NIS was queried for cases of OSP and RASP for the treatment of BPH between 2013 and 2016. Perioperative complications, unadjusted hospital cost and length of stay (LOS) were compared between RASP and OSP. Smoothed linear regression curves comparing hospitalisation cost by increasing LOS was stratified by surgical approach to identify point of cost equivalency between RASP and OSP. Multivariable linear regression analysis was used to construct a hospitalisation cost model to examine the contribution of the robotic approach and LOS to hospitalisation cost.

RESULTS

The total analytical cohort included 2551 OSP and 704 RASP procedures. Patients undergoing RASP were younger, at a median (interquartile range [IQR]) age of 68 (63-73) vs 71 (65-77) years, and with less comorbidity (76.8% vs 86.5%, P < 0.01). RASP was associated with fewer total complications (11.1% vs 29.2%, P < 0.01) and a greater likelihood of routine discharge to home rather than another facility (88.9% vs 76.7%, P < 0.01). While LOS was shorter with RASP (median [IQR], 2 [1-3] vs 4 [3-6] days, P < 0.01), total unadjusted hospitalisation cost (in United States dollars) was greater (median [IQR], $10 855 [$7965-$15 675] vs $13 467 [$10 572-$17 722], P < 0.01). Presence of any complication increased both LOS and hospitalisation cost (P < 0.01). Linear regression modelling determined the point of cost equivalence between RASP staying a median of 2 days was an OSP case staying between 5 and 6 days. On multivariable regression analysis, the robotic approach contributed an additional $6175 (P < 0.01) to the cost model, whereas each additional day of hospitalisation contributed $1687 (P < 0.01), suggesting LOS would need to be 3-4 days shorter with RASP to offset surgical costs of the robot.

CONCLUSIONS

While RASP appears to have significantly better perioperative complication rates with shorter LOS and likely discharge to home, total hospitalisation cost remained greater, likely related to upfront operative costs. While this retrospective study is limited by selection bias for patients undergoing RASP, the benefits of improved convalescence, discharge to home, and lower rate of perioperative complications appear to justify performance of RASP in an experienced pelvic robotic centre despite relatively greater hospitalisation cost if referral to an experienced holmium laser enucleation of the prostate centre is not feasible.

The feasibility and safety of photoselective vaporization for prostate using a 180-W XPS Greenlight laser in day-surgery pattern in China

To evaluate the feasibility and safety of photoselective vaporization for prostate (PVP) with a 180-W XPS Greenlight laser as day surgery in the Chinese population. We retrospectively collected 114 cases undergoing the day surgery PVP and 198 cases undergoing conventional inpatient surgery PVP from April 2017 to March 2020. All patients' data including baseline characteristics, peri-operative data, post-operative outcomes, and complications were recorded and evaluated. The day-surgery procedures were successful in 110 patients. There were no significant differences in baseline characteristics in both groups. The catheterization time and hospitalization time were much shorter and economic cost was much lower in the day-surgery group than in the conventional inpatient surgery group. As for the post-operative complications, the incidence rate of the urinary retention is higher in the day-surgery group than in conventional inpatient surgery group. During the follow-up periods, the International Prostate Symptom Score (IPSS), quality of life (QoL), maximal urinary flow rate (Qmax), and post-void residual urine (PVR) improved significantly in both groups, and no differences were observed between the two groups. Compared to the conventional inpatient surgery, the day-surgery PVP is feasible and safe, which can reduce the hospitalization time and economic cost.

Catheter Removal on the Same Day of Holmium Laser Enucleation of the Prostate: Outcomes of a Pilot Study

Objective

To determine if same day catheter removal is feasible in a select population after holmium laser enucleation of the prostate (HoLEP).

Methods

We performed an analysis of patients undergoing HoLEP at our institution who underwent same-day catheter removal after HoLEP. All HoLEPs were performed with Moses 2.0 Optimized for BPH. Patients were dismissed from postoperative recovery unit to the clinic for catheter removal and voiding trial.

Results

To date, 30 patients have undergone same day catheter removal. Median age is 68.6 years (interquartile range [IQR] 61.8-73.3) and preoperative prostate volume 81 mL (IQR 53-114.8). Median enucleation time was 39.5 minutes (IQR 30.5-53), morcellation time was 5 minutes (IQR 4-12 minutes), and enucleated specimen weight was 52.5 g (IQR 33-81). Twenty-seven (90%) patients successfully voided on the same day without requiring catheter replacement. All patients were catheter free by POD1. For patients who successfully passed their voiding trial, the median time from the end of the procedure to hospital discharge was 2.6 hours (IQR [2.1-2.9]) and from the end of the HoLEP to catheter removal was 4.9 hours (IQR [3.5-6.0]).

Conclusion

We present for the first time that same day catheter removal is a feasible option in a select population of patients undergoing HoLEP. With more study, this has the potential for transforming the management of BPH, especially larger glands.
