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

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

Association of 5α-Reductase Inhibitors with Depression and Suicide: A Mini Systematic Review and Meta-analysis.

5α-Reductase inhibitors (5-ARIs) are widely prescribed for treatment of benign prostatic obstruction and androgenic alopecia. Several studies with controversial findings regarding 5-ARI exposure have been published over a number of years, and concerns were recently raised about the potential risks of depression and suicide associated with 5-ARIs. To investigate this association, we conducted a systematic review of the literature and a meta-analysis. Five studies involving 2213600 patients met our inclusion criteria. We found no statistically significant association between 5-ARI exposure and the risk of depression (adjusted hazard ratio [aHR] 1.30, 95% confidence interval [CI] 0.85-2.00; p = 0.23) or suicide (aHR 1.30, 95% CI 0.65-2.61; p = 0.45). Subgroup analyses for finasteride and dutasteride revealed similar results. When restricting the analysis to patients without a prior diagnosis of depression, we observed similar findings (aHR for suicide 1.00, 95% CI 0.68-1.46; p = 0.98). PATIENT SUMMARY: We reviewed study data for more than two million patients taking drugs called 5α-reductase inhibitors (5-ARIs), which are widely prescribed for urinary problems caused by benign prostate enlargement and for male-pattern hair loss. In a pooled analysis we found no evidence of an association between 5-ARI use and the risk of depression or suicide.

[Should we all switch to en-bloc resection of bladder tumours?] / Sollten wir alle zur En Bloc Resektion von Blasentumoren wechseln?

In En-Bloc Resection of Bladder Tumours (ERBT), tumours are not removed in fragments, but are dissected in one layer and, if possible, extracted in one piece. This method represents a significant shift in the surgical management of non-muscle-invasive bladder tumours, providing multiple benefits over the traditional transurethral resection of the bladder (TUR-B). The histological analysis of ERBT specimens is more accurate, enhancing diagnostic precision. Additionally, the presence of detrusor muscle in ERBT specimens is more frequent, indicating a more complete removal of the tumours. Recent years have seen the consolidation of a robust evidence base emphasizing the advantages of ERBT. Notably, a multicentric, prospective randomized trial has recently revealed a significant reduction in recurrence rates at 12 months follow-up compared with TUR-B. Experienced endourologists should explore this technique, as it may soon become the standard of care. The technique's elegance and effectiveness make it too important to be ignored.

Ejaculation sparing of classic and minimally invasive surgical treatments of LUTS/BPH.

BACKGROUND: The surgical landscape for Lower Urinary Tract Symptoms (LUTS) and Benign Prostatic Hyperplasia (BPH) has evolved with the introduction of Minimally Invasive Surgical Therapies (MISTs), recognizing the impact of sexual function on patients' well-being, and prioritizing ejaculation-sparing approaches. METHODS: This systematic review explored ejaculation sparing after classic endoscopic procedures and MISTs (iTind, Rezum, Urolift, Aquablation, and TPLA) and a literature search yielded 41 studies. RESULTS: While all procedures demonstrated efficacy in improving LUTS/BPH symptoms (IPSS, QoL, Qmax), a subset of studies evaluated ejaculatory function. Positive outcomes were noted, challenging the historical association of BPH surgeries with ejaculatory dysfunction. Variations in study design, patient cohorts, and limited long-term data present challenges. Notably, the lack of baseline specificity, use of alpha-blockers, and non-specific sexual function assessments underscore potential biases. CONCLUSIONS: Despite limitations, the review tentatively concluded that MISTs, including iTind, Rezum, Urolift, Aquablation, and TPLA, appear comparable in sparing ejaculation. Long-term studies are essential to validate sustainability, and comparative research should assess trade-offs between MISTs and traditional surgeries. Incorporating patient-reported outcomes and quality of life assessments will enhance future investigations, refining MISTs as standard therapeutic options for LUTS/BPH.

Influence of Prostate Volume on the Incidence of Complications and Urinary Incontinence Following Thulium Fiber Laser Enucleation of the Prostate: Results from Multicenter, Real-world Experience of 2732 patients.

Background: The use of the new thulium fiber laser in enucleation of the prostate (ThuFLEP) has been introduced recently. Objective: To evaluate complications and urinary incontinence (UI) after ThuFLEP in small and large prostate volume (PV). Design setting and participants: We retrospectively reviewed patients who underwent ThuFLEP in six centers (from January 2020 to January 2023). The exclusion criteria were concomitant lower urinary tract surgery, previous prostate/urethral surgery, prostate cancer, and pelvic radiotherapy. Outcome measurements and statistical analysis: Patients were divided into two groups: group 1: PV ≤80 ml; group 2: PV >80 ml. Univariable and multivariable logistic regression analyses were performed to evaluate the independent predictors of overall UI. Results and limitations: There were 1458 patients in group 1 and 1274 in group 2. There was no significant difference in age. The median PV was 60 (61-72) ml in group 1 and 100 (90-122) ml in group 2. En bloc enucleation was employed more in group 1, while the early apical release technique was used more in group 2. The rate of prolonged irrigation for hematuria, urinary tract infection, and acute urinary retention did not differ significantly. Blood transfusion rate was significantly higher in group 2 (0.5% vs 2.0%, p = 0.001). There was no significant difference in the overall UI rate (12.3% in group 1 vs 14.7% in group 2, p = 0.08). A multivariable regression analysis showed that preoperative postvoiding urine residual (odds ratio 1.004, 95% confidence interval 1.002-1.007, p < 0.01) was the only factor significantly associated with higher odds of UI. A limitation of this study was its retrospective nature. Conclusions: Complications and UI rates following ThuFLEP were similar in patients with a PV up to or larger than 80 ml except for the blood transfusion rate that was higher in the latter. Patient summary: In this study, we looked at outcomes after thulium fiber laser in enucleation of the prostate stratified by PV. We found that blood transfusion was higher in men with PV >80 ml, but urinary incontinence was similar.

Antegrade ejaculation preservation in surgical treatment for benign prostatic hyperplasia: quest for balance between voiding and sexual function.

PURPOSE OF REVIEW: Surgical treatment of benign prostatic hyperplasia (BPH) carries a significant risk of ejaculation dysfunction. Preservation of antegrade ejaculation while providing effective, well tolerated, and durable treatment of BPH is a paramount component of physical and sexual well being for significant number of men. We reviewed available literature with an aim of providing status on antegrade ejaculation preserving BPH surgical therapies. RECENT FINDINGS: Minimally invasive surgical therapies for BPH have been developed over the last decade, with significant marketing emphasis on their potential for preservation of antegrade ejaculation. However, the question about durability of relief of bladder outlet obstruction remains. Parallel to this technological development, the understanding of anatomical structures involved in ejaculation have resulted in technical modifications of well established surgical treatments modalities like transurethral resection of prostate, endoscopic enucleation of prostate and simple prostatectomy, thereby providing safe and durable relief of bladder outlet obstruction secondary to BPH with a satisfactory preservation of antegrade ejaculation. SUMMARY: Preservation of antegrade ejaculation is an important goal for significant number of men needing BPH surgery. Novel minimally invasive surgical technologies have been developed for this purpose; but understanding of the anatomical structures essential for antegrade ejaculation have allowed technical modification of existing surgical techniques with excellent preservation of antegrade ejaculation.

High-power holmium laser versus thulium fiber laser for endoscopic enucleation of the prostate in patients with glands larger than 80 ml: Results from the Prostate Endoscopic EnucLeation study group.

Background: Endoscopic enucleation of the prostate (EEP) has gained acceptance as an equitable alternative to transurethral resection of the prostate for benign prostate hyperplasia (BPH). Our primary aim is to compare peri-operative outcomes of EEP using thulium fiber laser (TFL) against high-power holmium laser (HPHL) in hands of experienced surgeons for large prostates (≥80 ml in volume). Secondary outcomes were assess complications within 1 year of follow up. Materials and Methods: We retrospectively reviewed patients with benign prostatic hyperplasia who underwent EEP with TFL or HPHL in 13 centers (January 2019-January 2023). Patients with prostate volume ≥80 ml were included, while those with concomitant prostate cancer, previous prostate/urethral surgery, and pelvic radiotherapy were excluded. Results: Of 1,929 included patients, HPHL was utilized in 1,459 and TFL in 470. After propensity score matching (PSM) for baseline characteristics, 247 patients from each group were analyzed. Overall operative time (90 [70, 120] vs. 52.5 [39, 93] min, P < 0.001) and enucleation time (90 [70, 105] vs. 38 [25, 70] min, P < 0.001) were longer in the TFL group, with comparable morcellation time (13 [10, 19.5] vs. 13 [10, 16.5] min, P = 0.914). In terms of postoperative outcomes, there were no differences in 30-day complications such as acute urinary retention, urinary tract infection or sepsis. In the PSM cohort, univariable analyses showed that higher age, lower preoperative Qmax, higher preoperative PVRU, and longer operation time were associated with higher odds of postoperative incontinence, while 2-lobe enucleation had lower odds of incontinence compared to 3-lobe enucleation. Conclusions: This real-world study reaffirms that HPHL and TFL in large prostates are equally efficacious in terms of 30-day complications. TFL with the en-bloc technique has a shorter operative time which significantly improves short- and medium-term functional outcomes.

Incidence of complications and urinary incontinence following endoscopic enucleation of the prostate in men with a prostate volume of 80 ml and above: results from a multicenter, real-world experience of 2512 patients.

PURPOSE: To evaluate complications and urinary incontinence (UI) after endoscopic enucleation of the prostate (EEP) stratified by prostate volume (PV). METHODS: We retrospectively reviewed patients with benign prostatic hyperplasia who underwent EEP with different energy sources in 14 centers (January 2019-January 2023). INCLUSION CRITERIA: prostate volume ≥ 80 ml. EXCLUSION CRITERIA: prostate cancer, previous prostate/urethral surgery, pelvic radiotherapy. PRIMARY OUTCOME: complication rate. SECONDARY OUTCOMES: incidence of and factors affecting postoperative UI. Patients were divided into 3 groups. Group 1: PV = 80-100 ml; Group 2 PV = 101-200 ml; Group 3 PV > 200 ml. Multivariable logistic regression analysis was performed to evaluate independent predictors of overall incontinence. RESULTS: There were 486 patients in Group 1, 1830 in Group 2, and 196 in Group 3. The most commonly used energy was high-power Holmium laser followed by Thulium fiber laser in all groups. Enucleation, morcellation, and total surgical time were significantly longer in Group 2. There was no significant difference in overall 30-day complications and readmission rates. Incontinence incidence was similar (12.1% in Group 1 vs. 13.2% in Group 2 vs. 11.7% in Group 3, p = 0.72). The rate of stress and mixed incontinence was higher in Group 1. Multivariable regression analysis showed that age (OR 1.019 95% CI 1.003-1.035) was the only factor significantly associated with higher odds of incontinence. CONCLUSIONS: PV has no influence on complication and UI rates following EEP. Age is risk factor of postoperative UI.

Influence of Early Apical Release on Outcomes in Endoscopic Enucleation of the Prostate: Results From a Multicenter Series of 4392 Patients.

OBJECTIVE: To evaluate outcomes after laser endoscopic enucleation of the prostate (EEP) stratified by whether early apical release (EAR) was performed or not. METHODS: We retrospectively reviewed patients with clinical benign prostatic hyperplasia who underwent EEP with holmium or thulium fiber laser in 8 centers (January 2020-January 2022). EXCLUSION CRITERIA: previous prostate/urethral surgery, prostate cancer, pelvic radiotherapy, concomitant lower urinary tract surgery. One-to-one propensity score-matching was performed between patients with EAR vs no EAR, with covariates including age, prostate volume, diabetes mellitus, hypertension, preoperative indwelling catheter, IPSS, Qmax, enucleation, and laser types. Multivariable logistic regression analyses were performed to evaluate independent predictors of 30-day postoperative complications and urinary incontinence. RESULTS: EAR was performed in 2094 of 4392 included patients. The matched cohort consisted of 787 patients per arm. Total operation time was significantly longer in the EAR group (median 75 vs 67 minutes, P = .004). Early complications were higher in the EAR group (18.6% vs 12.5%, P = .001), while postoperative incontinence rates were similar (14.1% vs 13.1%, P = .61). Multivariable regression analysis showed that 3-lobe enucleation and operation time were significant predictors of postoperative complications; preoperative indwelling catheterization, higher prostate volume, and en-bloc enucleation were associated with higher odds of postoperative incontinence. LIMITATION: retrospective nature. CONCLUSION: Performing EAR during EEP is associated with a greater incidence of early complications, which was mainly driven by higher rates of postoperative hematuria and perioperative transfusion. The risk of postoperative incontinence and its duration are not affected by EAR.

[Imaging in nephroureterolithasis]. / Bildgebung bei Nephroureterolithiasis.

In the acute diagnostics of a suspected nephroureterolithiasis, ultrasonography should be the examination modality of choice. In cases of suspected urolithiasis, unclear flank pain with fever or in cases of a solitary kidney, a noncontrast computed tomography (CT) scan should always subsequently be performed. If the sonography findings are inconclusive in pregnant women a magnetic resonance imaging (MRI) examination can be considered. If there are indications for urinary diversion, a retrograde imaging study should be performed as part of the urinary diversion. This or CT imaging is also suitable for preinterventional imaging before shock wave lithotripsy, percutaneous nephrolithotomy or ureteroscopy. Postinterventional imaging is not always necessary and sonography is often sufficient. In a conservative treatment approach an abdominal plain X­ray can be used for follow-up assessment.

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

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

Experts' recommendations in laser use for the treatment of bladder cancer: a comprehensive guide by the European Section of Uro-Technology (ESUT) and Training and Research in Urological Surgery and Technology (TRUST)-Group.

PURPOSE: To identify laser settings and limits applied by experts during laser vaporization (vapBT) and laser en-bloc resection of bladder tumors (ERBT) and to identify preventive measures to reduce complications. METHODS: After a focused literature search to identify relevant questions, we conducted a survey (57 questions) which was sent to laser experts. The expert selection was based on clinical experience and scientific contribution. Participants were asked for used laser types, typical laser settings during specific scenarios, and preventive measures applied during surgery. Settings for a maximum of 2 different lasers for each scenario were possible. Responses and settings were compared among the reported laser types. RESULTS: Twenty-three of 29 (79.3%) invited experts completed the survey. Thulium fiber laser (TFL) is the most common laser (57%), followed by Holmium:Yttrium-Aluminium-Garnet (Ho:YAG) (48%), continuous wave (cw) Thulium:Yttrium-Aluminium-Garnet (Tm:YAG) (26%), and pulsed Tm:YAG (13%). Experts prefer ERBT (91.3%) to vapBT (8.7%); however, relevant limitations such as tumor size, number, and anatomical tumor location exist. Laser settings were generally comparable; however, we could find significant differences between the laser sources for lateral wall ERBT (p = 0.028) and standard ERBT (p = 0.033), with cwTm:YAG and pulsed Tm:YAG being operated in higher power modes when compared to TFL and Ho:YAG. Experts prefer long pulse modes for Ho:YAG and short pulse modes for TFL lasers. CONCLUSION: TFL seems to have replaced Ho:YAG and Tm:YAG. Most laser settings do not differ significantly among laser sources. For experts, continuous flow irrigation is the most commonly applied measure to reduce complications.

Minimally invasive techniques in quest of Holy Grail of surgical management of enlarged prostates: a narrative review.

PURPOSE: Past decade has seen a renewed interest in minimally invasive surgical techniques (MISTs) for management of enlarged prostate. This narrative review aims to explore newer MIST for benign prostatic hyperplasia (BPH) which are not yet integrated into established societal guidelines. METHODS: We conducted a literature search across PubMed, Google Scholar, and FDA ClinicalTrials.gov databases on June 1st, 2023, to identify studies published within the past decade exploring various MISTs for BPH. Additionally, we gathered insights from abstracts presented in meetings of professional associations and corporate websites. We broadly classified these procedures into three distinct categories: energy-based, balloon dilation, and implant/stent treatments. We collected detail information about the device, procedure details, its inclusion and exclusion criteria, and outcome. RESULTS: Our review reveals that newer energy-based MISTs include Transperineal Laser Ablation, Transurethral Ultrasound Ablation, and High-Intensity Focused Ultrasound. In the sphere of balloon dilation, Transurethral Columnar Balloon Dilation and the Optilume BPH Catheter System were gaining momentum. The noteworthy implants/stents that are on horizon include Butterfly Prostatic Retraction Device, Urocross Expander System, Zenflow Spring System, and ProVee Urethral Expander System. CONCLUSION: The exploration of various MISTs reflects ongoing efforts to enhance patient care and address limitations of existing treatments. This review provides a bird-eye view and valuable insights for urologists and researchers seeking to navigate the dynamic landscape of MISTs in the quest for effective and minimally invasive solutions for enlarged prostates.

Experts' recommendations in laser use for the treatment of urolithiasis: a comprehensive guide by the European Section of Uro-Technology (ESUT) and Training-Research in Urological Surgery and Technology (T.R.U.S.T.)-Group.

PURPOSE: To identify laser lithotripsy settings used by experts for specific clinical scenarios and to identify preventive measures to reduce complications. METHODS: After literature research to identify relevant questions, a survey was conducted and sent to laser experts. Participants were asked for preferred laser settings during specific clinical lithotripsy scenarios. Different settings were compared for the reported laser types, and common settings and preventive measures were identified. RESULTS: Twenty-six laser experts fully returned the survey. Holmium-yttrium-aluminum-garnet (Ho:YAG) was the primary laser used (88%), followed by thulium fiber laser (TFL) (42%) and pulsed thulium-yttrium-aluminum-garnet (Tm:YAG) (23%). For most scenarios, we could not identify relevant differences among laser settings. However, the laser power was significantly different for middle-ureteral (p = 0.027), pelvic (p = 0.047), and lower pole stone (p = 0.018) lithotripsy. Fragmentation or a combined fragmentation with dusting was more common for Ho:YAG and pulsed Tm:YAG lasers, whereas dusting or a combination of dusting and fragmentation was more common for TFL lasers. Experts prefer long pulse modes for Ho:YAG lasers to short pulse modes for TFL lasers. Thermal injury due to temperature development during lithotripsy is seriously considered by experts, with preventive measures applied routinely. CONCLUSIONS: Laser settings do not vary significantly between commonly used lasers for lithotripsy. Lithotripsy techniques and settings mainly depend on the generated laser pulse's and generator settings' physical characteristics. Preventive measures such as maximum power limits, intermittent laser activation, and ureteral access sheaths are commonly used by experts to decrease thermal injury-caused complications.

Comparison Between Thulium Fiber Laser and High-power Holmium Laser for Anatomic Endoscopic Enucleation of the Prostate: A Propensity Score-matched Analysis from the REAP Registry.

BACKGROUND: Different lasers have been developed for treatment of benign prostatic hyperplasia, with no definitively superior technique identified to date. OBJECTIVE: To compare surgical and functional enucleation outcomes in real-world multicentre practice using high-power holmium laser (HP-HoLEP) and thulium fiber laser enucleation of the prostate (ThuFLEP) for different prostate sizes. DESIGN, SETTING, AND PARTICIPANTS: The study included 4216 patients who underwent HP-HoLEP or ThuFLEP at eight centers in seven countries between 2020 and 2022. Exclusion criteria were previous urethral or prostatic surgery, radiotherapy, or concomitant surgery. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: To adjust for the bias arising from different characteristics at baseline, propensity score matching (PSM) was used to identify 563 matched patients in each cohort. Outcomes included the incidence of postoperative incontinence, early complications (30-d), and delayed complications, and results for the International Prostate Symptom Score (IPSS), quality of life (QoL), maximum flow rate (Qmax), and postvoid residual volume (PVR). RESULTS AND LIMITATIONS: After PSM, 563 patients in each arm were included. Total operative time was similar between the arms, but enucleation and morcellation times were significantly longer for ThuFLEP. The rate of postoperative acute urinary retention was higher in the ThuFLEP arm (3.6% vs 0.9%; p = 0.005), but the 30-d readmission rate was higher in the HP-HoLEP arm (22% vs 8%; p = 0.016). There was no difference in postoperative incontinence rates (HP-HoLEP:19.7%, ThuFLEP:16.0%; p = 0.120). Rates of other early and delayed complications were low and comparable between the arms. The ThuFLEP group had higher Qmax (p < 0.001) and lower PVR (p < 0.001) than the HP-HoLEP group at 1-yr follow-up. The study is limited by its retrospective nature. CONCLUSIONS: This real-world study shows that early and delayed outcomes of enucleation with ThuFLEP are comparable to those with HP-HoLEP, with similar improvements in micturition parameters and IPSS. PATIENT SUMMARY: As lasers become readily available for the treatment of enlarged prostates causing urinary bother, urologists should focus on performing good anatomic removal of prostate tissue, with the choice of laser not as important for good outcomes. Patients should be counseled about long-term complications, even when the procedure is being performed by an experienced surgeon.

Suction in Percutaneous Nephrolithotripsy: Evolution, Development, and Outcomes from Experimental and Clinical studies. Results from a Systematic Review.

CONTEXT: Controversy exists regarding the therapeutic benefit of suction use during percutaneous nephrolithotripsy (PCNL). OBJECTIVE: To review and highlight the options available in the use of suction for PCNL, and to discuss their strengths and limitations. EVIDENCE ACQUISITION: A systematic literature search was performed using Scopus, EMBASE, and PubMed. Thirty four studies were included. There was one ex vivo study. Among clinical studies, 24 used a vacuum/suctioning sheath and nine a handpiece suction device/direct-in-scope suction. The suction technique was employed in standard, mini-PCNL, supermini-PCNL, and enhanced supermini­PCNL techniques. EVIDENCE SYNTHESIS: Handpiece suction devices demonstrated better safety and efficiency in treating large stones than nonsuction PCNL and in a much shorter time. Trilogy and ShockPulse-SE were equally effective, safe, and versatile for standard PCNL and mini-PCNL. The heavier handpiece makes Trilogy less ergonomically friendly. Laser suction handpiece devices can potentiate laser lithotripsy by allowing for better laser control with simultaneous suction of small fragments and dust. Integrated suction-based sheaths are available in reusable and disposable forms for mini-PCNL only. Mini-PCNL with suction reported superior outcomes for operative time and stone-free rate to mini-PCNL. This also helped minimize infectious complications by a combination of intrarenal pressure reduction and faster aspiration of irrigation fluid reducing the risk of sepsis, enhance intraoperative vision, and improve lithotripsy efficiency, which makes it a very attractive evolution for PCNL. CONCLUSIONS: Suction devices in PCNL are reforming the way PCNL is being done. Adding suction to mini-PCNL reduces infectious complications and improves the stone-free rate. Our review shows that despite the limited evidence, suction techniques appear to improve PCNL outcomes. PATIENT SUMMARY: In this review, we looked at the intra- and perioperative outcomes of percutaneous nephrolithotripsy (PCNL) with the addition of suction. With better stone fragmentation and fewer postoperative infections, this technology is very useful particularly for mini-PCNL.

Results from a global multicenter registry of 6193 patients to refine endoscopic anatomical enucleation of the prostate (REAP) by evaluating trends and outcomes and nuances of prostate enucleation in a real-world setting.

PURPOSE: To collect a multicentric, global database to assess current preferences and outcomes for endoscopic enucleation of the prostate (EEP). METHODS: Endourologists experienced in EEP from across the globe were invited to participate in the creation of this retrospective registry. Surgical procedures were performed between January 2020 and August 2022. INCLUSION CRITERIA: lower urinary tract symptoms not responding to or worsening despite medical therapy and absolute indication for surgery. EXCLUSION CRITERIA: prostate cancer, concomitant lower urinary tract surgery, previous prostate/urethral surgery, pelvic radiotherapy. RESULTS: Ten centers from 7 countries, involving 13 surgeons enrolled 6193 patients. Median age was 68 [62-74] years. 2326 (37.8%) patients had large prostates (> 80 cc). The most popular energy modality was the Holmium laser. The most common technique used for enucleation was the 2-lobe (48.8%). 86.2% of the procedures were performed under spinal anesthesia. Median operation time was 67 [50-95] minutes. Median postoperative catheter time was 2 [1, 3] days. Urinary tract infections were the most reported complications (4.7%) followed by acute urinary retention (4.1%). Post-operative bleeding needing additional intervention was reported in 0.9% of cases. 3 and 12-month follow-up visits showed improvement in symptoms and micturition parameters. Only 8 patients (1.4%) required redo surgery for residual adenoma. Stress urinary incontinence was reported in 53.9% of patients and after 3 months was found to persist in 16.2% of the cohort. CONCLUSION: Our database contributes real-world data to support EEP as a truly well-established global, safe minimally invasive intervention and provides insights for further research.

Experts' recommendations in laser use for the treatment of upper tract urothelial carcinoma: a comprehensive guide by the European Section of Uro-Technology (ESUT) and Training Research in Urological Surgery and Technology (T.R.U.S.T.) group.

PURPOSE: To highlight and compare experts' laser settings during endoscopic laser treatment of upper tract urothelial carcinoma (UTUC), to identify measures to reduce complications, and to propose guidance for endourologists. METHODS: Following a focused literature search to identify relevant questions, a survey was sent to laser experts. We asked participants for typical settings during specific scenarios (ureteroscopy (URS), retrograde intrarenal surgery (RIRS), and percutaneous treatment). These settings were compared among the reported laser types to find common settings and limits. Additionally, we identified preventive measures commonly applied during surgery. RESULTS: Twenty experts completed the survey, needing a mean time of 12.7 min. Overall, most common laser type was Holmium-Yttrium-Aluminum-Garnet (Ho:YAG) (70%, 14/20) followed by Thulium fiber laser (TFL) (45%, 9/20), pulsed Thulium-Yttrium-Aluminum-Garnet (Tm:YAG) (3/20, 15%), and continuous wave (cw)Tm:YAG (1/20, 5%). Pulse energy for the treatment of distal ureteral tumors was significantly different with median settings of 0.9 J, 1 J and 0.45 J for Ho:YAG, TFL and pulsed Tm:YAG, respectively (p = 0.048). During URS and RIRS, pulse shapes were significantly different, with Ho:YAG being used in long pulse and TFL in short pulse mode (all p < 0.05). We did not find further disparities. CONCLUSION: Ho:YAG is used by most experts, while TFL is the most promising alternative. Laser settings largely do not vary significantly. However, further research with novel lasers is necessary to define the optimal approach. With the recent introduction of small caliber and more flexible scopes, minimal-invasive UTUC treatment is further undergoing an extension of applicability in appropriately selected patients.
