HoLEP Learning Curve-Resident Perspective: Survey of Senior Residents from High-Volume Tertiary Center.

Objective: We aim to report the learning curve and experience performing holmium laser enucleation of the prostate (HoLEP) from a resident standpoint trained at a tertiary high-volume center. Methods: An electronic survey was distributed to 10 surveyees that included recently graduated chief residents trained at Indiana University in the past 3 years i.e., between 2020 and 2022 with a 100% response rate. The questionnaire focused on HoLEP training experience based on a recently established mentorship curriculum in training the residents through each individual step of the surgery. Results: The average learning curve for performing HoLEP was reported to be greater than 25 cases with 50% of the residents reporting >50 cases to master the technique. The surgical difficulty of steps of the HoLEP were rated on a subjective scale of 1-5: 1 = very easy, 2 = easy, 3 = neutral, 4 = hard, and 5 = very hard. The common challenging steps in decreasing the order of difficulty as reported are performing apical enucleation, joining anterior and posterior planes, and dividing anterior commissure with a mean rating of 3.5, 3.1, and 3.1, respectively. The most difficult aspect of the surgery to master was performing apical dissection (60%). Comparing operative parameters for HoLEP with transurethral resection of the prostate in aspects of resection volume and times, 70% of candidates reported it better for HoLEP whereas 20% had similar times for both procedures. A total of 90% of the residents felt confident to offer HoLEP as part of their practice without the need for any further training. Regarding the initial challenge of including HoLEP surgery in practice, the majority (60%) reported difficulty with equipment set up in their practice while 20% reported difficulty maintaining efficient operating room (OR) times and turnover. Conclusion: We believe HoLEP can be performed immediately after residency training and incorporated into practice with high volume, repeated exposure to HoLEP surgery throughout residency based on study results. The average learning curve reported for performing HoLEP was greater than 25 cases.

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

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

Laser Technology Advancements in the Treatment of Benign Prostatic Hypertrophy.

PURPOSE OF REVIEW: Lasers have had a significant impact on the treatment of benign prostatic hypertrophy. This article attempts to distill the advancements in laser technology for the treatment of benign prostatic hypertrophy (BPH) into key and understandable points to help make this topic more accessible to urologists. RECENT FINDINGS: The holmium:yttrium-aluminum-garnet (YAG) laser, one of the most significant lasers in the field of urology, has recently been improved with pulse modulating technology (Moses™ technology). New thulium:YAG technology allows both pulsed and continuous wave modes. The thulium fiber laser is one of the newer lasers to come to market and has been shown to have effective and safe outcomes. GreenLight™ lasers are predominantly used in photovaporization procedures and have also been studied extensively, although less in recent years. The modern urologist is fortunate to have many high-quality lasers and a wide variety of surgical techniques to choose from when treating BPH. Understanding the basic laser principles and applications will help urologists to select the best treatment options for their patients with BPH.

Prospective Multicenter Evaluation of Pain Before and After Removal of Nonobstructing Renal Calculi: A CoRE Initiative.

PURPOSE: Flank pain associated with stone disease is typically caused by a stone that obstructs urine flow. However, it is plausible that nonobstructing kidney stones may still cause pain. We performed a multicenter, observational trial to evaluate whether treatment of small nonobstructing calyceal stones improves pain and kidney stone-specific health-related quality of life. MATERIALS AND METHODS: Patients aged 18 years or older with nonobstructing renal stone(s) up to 10 mm in longest diameter and moderate to severe pain were recruited. All participants completed 3 questionnaires: the Brief Pain Inventory (BPI), the Patient-Reported Outcomes Measurement Information System pain interference form 6a, and the Wisconsin Stone Quality of Life questionnaire. Thereafter, all participants underwent ureteroscopy for renal stone treatment. All 3 questionnaires were repeated at 2, 6 to 8, and at 12 weeks postprocedure. The primary outcomes were change in preoperative to 12-week postoperative mean BPI score and worst BPI pain score. RESULTS: A total of 43 patients with nonobstructing kidney stones and associated flank pain were recruited. All stones were removed. Preoperatively, BPI scores for mean pain and worst pain were 5.5 and 7.2, respectively which decreased to 1.8 and 2.8 respectively at 12 weeks postoperatively. Wisconsin Stone Quality of Life questionnaire mean score increased from 70.4 to 115.3 at 12 weeks postoperatively. A total of 86% and 69% of patients had at least a 20% and 50% reduction in their mean pain scores, respectively. CONCLUSIONS: This study determined that patients benefit significantly from the removal of calyceal nonobstructing kidney stones for at least 12 weeks with a reduction in pain and an increase in quality of life. Therefore, surgical removal of these stones in this patient population should be offered as a treatment option.

Evaluation of Renal Function Recovery After Holmium Laser Enucleation of the Prostate in Patients with Chronic Kidney Disease.

Introduction: Holmium laser enucleation of the prostate (HoLEP) has become a new surgical gold standard treatment for benign prostatic hyperplasia (BPH). It is known that untreated BPH can lead to bladder outlet obstruction (BOO). A positive correlation exists between BOO and chronic kidney disease (CKD), but stability or recovery of renal function after HoLEP remains unknown. We sought to describe changes in renal function after HoLEP in men with CKD. Methods: A retrospective study was conducted of patients who underwent HoLEP with glomerular filtration rates (GFRs) <60, CKD stages III to V. Pre- and postoperative GFRs were selected within 3 months before the operation and within 1 year postoperatively. The presence of an indwelling catheter, preoperative hydronephrosis, history of kidney stones, and prostate size were also reviewed. Data were analyzed in accordance with preoperative CKD stage. Results: Of the reviewed patients, 138 met inclusion criteria with CKD stages III to V. Each CKD group was without significant postoperative complications. There was a significant increase between pre- and postoperative GFR for patients in CKD stages III (n = 116) and IV (n = 17) (p < 0.0001 and p = 0.010, respectively). The mean increase between pre- and postoperative GFR for the CKD stages III and IV patients were 6.4 and 6.49, respectively. There was no correlation between presence of preoperative hydronephrosis, history of kidney stones, catheter dependency, nor prostate size on change in postoperative GFR (p > 0.05). Conclusion: These findings suggest that patients in CKD stages III or IV undergoing HoLEP experience an increase in GFR. It is noteworthy that there appears to be no decline in renal function postoperatively in any group. HoLEP represents an excellent surgical option for patients with preoperative CKD and may prevent further renal decline.

Percutaneous Cystolitholapaxy Is Safe and Effective in Adult Patients With Lower Urinary Tract Reconstruction Utilizing Bowel.

OBJECTIVE: To investigate the safety, efficacy, and surgical approach of percutaneous bladder calculi removal in adult patients with prior lower urinary tract reconstruction utilizing bowel using a single-institution database. METHODS: Twenty patients with prior history of lower urinary tract reconstruction (continent cutaneous urinary reservoir, augmentation enterocystoplasty with catheterizable channel, or ileal neobladder) who underwent percutaneous cystolitholapaxy from 2014 to 2020 were identified from an IRB-approved database. Analysis of patient demographics, operative details, stone composition, stone-free rates, recurrence, and associated complications was performed. RESULTS: Percutaneous access and either ultrasonic lithotripter or laser lithotripsy were utilized to remove bladder stones. Over half of the patients also underwent concomitant renal stone removal via percutaneous removal or retrograde ureteroscopy. Postoperative computed tomography imaging revealed complete bladder stone clearance in 90% of patients. There were no notable complications from percutaneous bladder stone removal and most patients were discharged either the same day or within 24hours. Urine and stone analysis revealed infection was present in the majority of patients. Bladder stones recurred in 45% of patients after more than 2years of follow-up, on average. CONCLUSION: Percutaneous cystolitholapaxy is a safe and effective approach for the removal of moderate-sized bladder calculi in adults with prior lower urinary tract reconstruction utilizing bowel. Its efficacy and minimally invasive nature make it the approach of choice at our institution.

Mini-Percutaneous Nephrolithotomy Outcomes in the Obese Population: A Retrospective Review.

Introduction and Objectives: Mini-percutaneous nephrolithotomy (PCNL) has gained popularity over the last decade due to its stone-free rate comparable to traditional PCNL but with decreased risk of complications. While the data on mini-PCNL has been favorable thus far, no study today has evaluated outcomes in obese patients. Methods: All patients undergoing mini-PCNL at our institution since we began its use in 2019 were included in this study. Mini-PCNL was defined as access sheath ≤22F in size. An obese group with body mass index (BMI) ≥30 was compared to a nonobese group with BMI <30. A patient was considered relatively stone free if residual fragments were <4 mm on follow-up CT with ≤3 mm cuts. Fisher exact test was used to compare dichotomous differences between variables, and t-test to compare continuous variables. Results: We identified 67 patients who underwent mini-PCNL during the study period with 33 patients in the obese group. Median BMI in the obese group was 36.4 kg/m2 compared to 25.05 kg/m2 in nonobese. There were no blood transfusions in either group during the study period. There was no statistical difference between the obese vs nonobese group for age, access sheath size, change in hemoglobin, same day discharge, percent relatively stone free, emergency department visit within 30 days, and median largest single stone diameter. There was a significant difference in the sum of all treated stone diameter in the obese group (median 15 mm) vs nonobese (median 18 mm, p = 0.02) (Table 1). Conclusion: Mini-PCNL appears to be equally safe and effective in obese and nonobese patients alike. While there was a statistically significantly higher amount of overall stone burden in the nonobese groups, the overall difference is not clinically significant. Further research is needed to validate our experience.

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.

The Uniform grading tooL for flexIble ureterorenoscoPes (TULIP-tool): a Delphi consensus project on standardised evaluation of flexible ureterorenoscopes.

OBJECTIVE: To develop a standardised tool to evaluate flexible ureterorenoscopes (fURS). MATERIALS AND METHODS: A three-stage consensus building approach based on the modified Delphi technique was performed under guidance of a steering group. First, scope- and user-related parameters used to evaluate fURS were identified through a systematic scoping review. Then, the main categories and subcategories were defined, and the expert panel was selected. Finally, a two-step modified Delphi consensus project was conducted to firstly obtain consensus on the relevance and exact definition of each (sub)category necessary to evaluate fURS, and secondly on the evaluation method (setting, used tools and unit of outcome) of those (sub)categories. Consensus was reached at a predefined threshold of 80% high agreement. RESULTS: The panel consisted of 30 experts in the field of endourology. The first step of the modified Delphi consensus project consisted of two questionnaires with a response rate of 97% (n = 29) for both. Consensus was reached for the relevance and definition of six main categories and 12 subcategories. The second step consisted of three questionnaires (response rate of 90%, 97% and 100%, respectively). Consensus was reached on the method of measurement for all (sub)categories. CONCLUSION: This modified Delphi consensus project reached consensus on a standardised grading tool for the evaluation of fURS - The Uniform grading tooL for flexIble ureterorenoscoPes (TULIP) tool. This is a first step in creating uniformity in this field of research to facilitate future comparison of outcomes of the functionality and handling of fURS.

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.

Evaluation of the Cost-Effectiveness of Surgical Treatment Options for Benign Prostatic Hyperplasia.

OBJECTIVE: To compare the cost-effectiveness of surgical interventions for BPH. METHODS: Using a Markov model, a cost-utility analysis was performed comparing HoLEP, B-TURP, WVTT, and PUL for prostate size <80cc (index patient 1) and HoLEP and SP for prostate size >80cc (index patient 2). Model probabilities and utility values were drawn from the literature. Analysis was performed at a 5-year time horizon with extrapolation to a lifetime horizon. Primary outcomes included quality-adjusted life years (QALYs), 2021 Medicare costs, and incremental cost-effectiveness ratios (ICERs) with a willingness-to-pay threshold of $100,000/QALY. Univariate and probabilistic sensitivity analyses were performed. RESULTS: At 5 years, costs per patient for index patient 1 were $3292 (WVTT), $6532 (HoLEP), $6670 (B-TURP), and $10,257 (PUL). HoLEP resulted in the highest QALYs (4.66), followed by B-TURP (4.60), PUL (4.38), and WVTT (4.38). This translated to HoLEP being most cost-effective (ICER $11,847). For index patient 2, HoLEP was less costly ($6,585 vs $15,404) and more effective (4.654 vs 4.650) relative to SP. On sensitivity analysis for index patient 1, B-TURP became most cost-effective if cost of HoLEP increased two-fold or chronic stress incontinence following HoLEP increased ten-fold. When follow-up time was varied, WVTT was preferred at very short follow up (<1 year), and HoLEP became more strongly preferred with longer follow up. CONCLUSION: At 5 years follow up, HoLEP is a cost-effective surgical treatment for BPH- independent of gland size.

Heterogeneity in stone culture protocols and endourologist practice patterns: a multi-institutional survey.

Kidney stone cultures can be beneficial in identifying bacteria not detected in urine, yet how stone cultures are performed among endourologists, under what conditions, and by what laboratory methods remain largely unknown. Stone cultures are not addressed by current clinical guidelines. A comprehensive REDCap electronic survey sought responses from directed (n = 20) and listserv elicited (n = 108) endourologists specializing in kidney stone disease. Questions included which clinical scenarios prompt a stone culture order, how results influence post-operative antibiotics, and what microbiology lab protocols exist at each institution with respect to processing and resulting stone cultures. Logistic regression statistical analysis determined what factors were associated with performing stone cultures. Of 128 unique responses, 11% identified as female and the mean years of practicing was 16 (range 1-46). A specific 'stone culture' order was available to only 50% (64/128) of those surveyed, while 32% (41/128) reported culturing stone by placing a urine culture order. The duration of antibiotics given for a positive stone culture varied, with 4-7 days (46%) and 8-14 days (21%) the most reported. More years in practice was associated with fewer stone cultures ordered, while higher annual volume of percutaneous nephrolithotomy was associated with ordering more stone cultures (p < 0.01). Endourologists have differing practice patterns with respect to ordering stone cultures and utilizing the results to guide post-operative antibiotics. With inconsistent microbiology lab stone culture protocols across multiple institutions, more uniform processing is needed for future studies to assess the clinical benefit of stone cultures and direct future guidelines.

Over-the-Counter Alkali Agents to Raise Urine pH and Citrate Excretion: A Prospective Crossover Study in Healthy Adults.

OBJECTIVE: To assess the effect of 2 over-the-counter alkalizing agents on 24 hour urinary parameters. MATERIALS AND METHODS: Ten healthy volunteers without a history of kidney stones were recruited to complete a baseline 24 hour urinalysis with a 4 day diet inventory. Participants then maintained the same diet on either LithoLyte (20 mEq 2 times per day) or KSPtabs (1 tablet 2 times per day) and submitted another 24 hour urinalysis. The process was repeated with the other supplement. Urinary alkali parameters were compared to baseline, and side effects were elicited with a questionnaire. RESULTS: LithoLyte intake resulted in a non-significant increase in citrate (597-758 mg/day, P =.058, an increase in urine pH (6.46-6.66, P =.028), and a decrease in urine ammonium (41-36 mmol/day, P =.005) compared to baseline. KSPtabs resulted in an increase in citrate (597-797 mg/day, P =.037) and urine pH (6.46-6.86, P =.037), with a non-significant decrease in ammonium (41-34 mmol/day, P =.059). No significant differences were seen comparing urinary analytes between LithoLyte and KSPtabs. With Litholyte, no side effects, mild, moderate, and severe side effects were seen in 50%, 40%, 10%, and 0%, respectively. With KSPtabs, rates were 60%, 20%, 10%, and 10%, respectively. CONCLUSION: In healthy participants without a history of kidney stones, LithoLyte and KSPtabs are effective over-the-counter alkali supplements, with a similar side effect profile to prescription potassium citrate.

Cost-Effectiveness of 90-day Single-use Flexible Cystoscope Trial: Single Center Micro-Costing Analysis and User Satisfaction.

OBJECTIVE: To evaluate cost-effectiveness and user satisfaction of a single-use flexible cystoscope at a tertiary care center we conducted a 90-day trial. Single-use flexible cystoscope advancements have introduced alternative options to reusable scopes. However, there is a paucity of cost-effectiveness and provider satisfaction studies examining the implementation of a hospital-based transition to single-use cystoscopes. METHODS: Following institutional device-approval we initiated a 90-day trial period (November 1, 2020-January 29, 2021) where all flexible, transurethral, and percutaneous, urologic care was provided with a disposable AMBU aScope. We performed a micro-costing analysis examining payor per case cost of the reusable flexible cystoscope (including servicing and processing) to the disposable units. Provider surveys assessed visual quality, deflection, ease of working channel and overall satisfaction on a 10-point Likert scale. RESULTS: Over the 90-day period, we encountered 84 cases (78 operative, 5 inpatient, 1 emergency department) where flexible cystoscopy was required. One disposable flexible cystoscope was successfully used in 78 of 84 (93%) cases. Of the 6 failures, 2 were due to an inability to access a disposable scope/monitor. Per use cost of the reusable flexible cystoscope at our center was $272.41 versus $185.00 for the single use. Extrapolating our average case volume and conservative failure rate (3 single use failures/month, requiring reusable), transitioning to predominately single use scopes results in $39,142.84 annual cost savings. CONCLUSIONS: This single center 90-day trial of disposable flexible cystoscopy identified per-use costs to be less when a single-use flexible cystoscope was utilized at a high-volume tertiary care center.

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.

Expanded Criteria Same Day Catheter Removal After Holmium Laser Enucleation of the Prostate.

Abstract 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 after HoLEP was described at our institution in 2020 after a 30-patient pilot trial. We now present an expanded update after widespread adoption at our facility. Methods: We reviewed patients who underwent same day catheter removal after HoLEP between January 1, 2020 and March 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 ± 61.5 cc, 35% were dependent on catheterization for urinary retention preoperatively and 9% were on antiplatelet/anticoagulant therapy. A total of 26.5% of patients with American Society of Anesthesiology score (ASA) 3 or 4 failed catheter removal compared with 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). Effective catheter removal was not significantly associated with age, body mass index, prostate size, catheter dependency, anticoagulation/antiplatelet therapy, American Urologic Association symptom score, prior BPH surgery, or prostate cancer in final pathology report. 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.
