in 2016 announced a novel acronym for transurethral ...Endoscopic Enucleation of the Prostate (EEP). This was inspired by a meta-analysis on randomized controlled trials on Holmium Laser Enucleation of the Prostate (HolEP) and bipolar enucleation versus open simple prostatectomy. EEP codes for the common ground of both techniques: “anatomical enucleation.” Although study quality with regard to the availability of long-term randomized controlled trials is at the moment mostly available for HoLEP, and bipolar enucleation, the existing data of all other enucleating techniques that have been demonstrated to perform anatomical enucleation as well should also been summarized under the same term. This editorial is a call for embracing this acronym of EEP for all anatomical enucleating techniques in order to serve for the transition from the age of TURP and open prostatectomy toward the age of EEP.

Abstract Context The European Association of Urology (EAU) Guidelines Office has set up a guideline working panel to analyse the scientific evidence published in the world literature on lasers in ...urologic practice. Objective Review the physical background and physiologic and technical aspects of the use of lasers in urology, as well as current clinical results from these new and evolving technologies, together with recommendations for the application of lasers in urology. The primary objective of this structured presentation of the current evidence base in this area is to assist clinicians in making informed choices regarding the use of lasers in their practice. Evidence acquisition Structured literature searches using an expert consultant were designed for each section of this document. Searches were carried out in the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, and Medline and Embase on the Dialog/DataStar platform. The controlled terminology of the respective databases was used, and both Medical Subject Headings and EMTREE were analysed for relevant entry terms. One Cochrane review was identified. Evidence synthesis Depending on the date of publication, the evidence for different laser treatments is heterogeneous. The available evidence allows treatments to be classified as safe alternatives for the treatment of bladder outlet obstruction in different clinical scenarios, such as refractory urinary retention, anticoagulation, and antiplatelet medication. Laser treatment for bladder cancer should only be used in a clinical trial setting or for patients who are not suitable for conventional treatment due to comorbidities or other complications. For the treatment of urinary stones and retrograde endoureterotomy, lasers provide a standard tool to augment the endourologic procedure. Conclusions In benign prostatic obstruction (BPO), laser vaporisation, resection, or enucleation are alternative treatment options. The standard treatment for BPO remains transurethral resection of the prostate for small to moderate size prostates and open prostatectomy for large prostates. Laser energy is an optimal treatment method for disintegrating urinary stones. The use of lasers to treat bladder tumours and in laparoscopy remains investigational.
Interaction-free usage (IfU) will be one of the quantitatively dominant forms of computer use in the future. In qualitative terms, this form of use will cover a wide range of applications, also ...software that supports communication and cooperation. Digital twins for cooperation and communication will be employed by individual users to maintain a variety of social networking activities. Generative AI will play a decisive role in this development, autonomously identifying user needs, replacing the predominant form of use through prompting with question-and-answer dialogs. These dialogs will also be used to preconfigure systems for IfU phases. The counterpart to IfU, which will become ever less-frequent, is intervening interaction, when users intervene to explore and adjust the performance of AI-based systems in exceptional situations or to optimize them for future task handling.
En bloc resection of bladder tumors (ERBT) orginally described in 1980 and adopted by few centers in the late 1990s has regained attention in the 2010s as a renaissance of a technique with high ...potential. The advent of new lasers indirectly lead to a better understanding of anatomical dissection from the experience in anatomical dissection in endoscopic enucleation of the prostate. 12 years after the reintroduction of ERBT evidence mounts that it is not only equivalent but better in some regards. However, ERBT still falls short with regard to wide adoption despite the striking technique inherent and reproducible features of accurate staging and specimen quality as requested by pathologist, as well and despite the high intraoperative safety and fast adoption of this technique even in early phase of training. The editorial walks the reader through the timeline of the renaissance speculating why there is a blockage between cognitive understanding and dissonance in surgical practice. The special issues presents the meta-analysis of surgical and oncological data on one hand and the level of understanding and power of this surgical technique in fields offsite oncological results in training achieving results almost right from the start after adoptation. Unlike in earlier years reviewing the literature of ERBT in 2023, ERBT seems not only to be a viable alternative, but something one should turn towards no to underperform with regards to the endpoints achievable by ERBT in a critical disease like bladder cancer.
Purpose
To evaluate the efficacy and safety of transurethral enucleation of the prostate (TUEP) versus transvesical open prostatectomy (OP) for the management of large benign prostatic hyperplasia ...(BPH).
Methods
Randomized controlled trials (RCTs) comparing TUEP and OP were identified from PubMed, Embase and Web of Science up to February 28, 2015. A meta-analysis was conducted with the STATA 12.0 software.
Results
Nine RCTs including 758 patients were enrolled in our meta-analysis. There were no significant differences between the two groups in the maximum urinary flow rate at 1, 3, 6 months, 1 and 2 years: postvoiding residual urinary volume, prostate-specific antigen, international prostate symptom score and quality of life score at 1, 3, 6 months and 1 year; or international index of erectile function at 3, 6 months and 1 year. Perioperative outcomes including hemoglobin level drop, catheter period, irrigation length and hospital stay favored TUEP, while operative time and resected prostate weight favored OP. There was significantly less blood transfusion with TUEP, but no significant differences were found in other complications such as recatheterization, urinary tract infection, reintervention for clots and bleeding control, incidence of pneumonia and infarction, transient incontinence, bladder neck contracture, urethral stricture and recurrent adenoma.
Conclusions
TUEP can be performed effectively and safely with functional outcomes and complications similar to OP for large BPH, whereas it has the advantages of a shorter catheter period, shorter hospital stays and less blood transfusion. These findings seem to support TUEP as the next-generation “gold standard” of surgery for large BPH.
Abstract Context Laser treatment of benign prostatic obstruction (BPO) has become more prevalent in recent years. Although multiple surgical approaches exist, there is confusion about laser–tissue ...interaction, especially in terms of physical aspects and with respect to the optimal treatment modality. Objective To compare available laser systems with respect to physical fundamentals and to discuss the similarities and differences among introduced laser devices. Evidence acquisition The paper is based on the second expert meeting on the laser treatment of BPO organised by the European Association of Urology Section of Uro-Technology. A systematic literature search was also carried out to cover the topic of laser treatment of BPO extensively. Evidence synthesis The principles of generation of laser radiation, laser fibre construction, the types of energy emission, and laser–tissue interaction are discussed in detail for the laser systems used in the treatment of BPO. The most relevant laser systems are compared and their physical properties discussed in depth. Conclusions Laser treatment of BPO is gaining widespread acceptance. Detailed knowledge of the physical principles allows the surgeon to discriminate between available laser systems and their possible pitfalls to guarantee high safety levels for the patient.
Objective To compare the clinical outcomes between thulium laser transurethral enucleation of the prostate (ThuLEP) (70 W) and holmium laser transurethral enucleation of the prostate (HoLEP) (90 W) ...in a prospective randomized trial with 18 months of follow-up. Both ThuLEP and HoLEP effectively relieve the obstructive symptoms due to benign prostatic hyperplasia (BPH). Methods A total of 133 consecutive patients with BPH were randomized to either ThuLEP (n = 71) or HoLEP (n = 62). An energy setting of 70 W and 90 W was used for the thulium and holmium laser in the enucleation procedure, respectively. The mushroom technique was used to fragment the enucleated lobes with the resection loop. The preoperative and postoperative parameters were compared. Results ThuLEP required a longer operation time (72.4 vs 61.5 minutes, P = .034) but resulted in less blood loss than HoLEP (130.0 vs 166.6 mL, P = .045). The catheterization time was comparable. At 18 months, the lower urinary tract symptom indexes were improved significantly in both groups compared with the baseline values. The International Prostate Symptom Score decreased to 5.2 in the ThuLEP group and 6.2 in the HoLEP group. The quality of life score and peak urinary flow rate were similar between the 2 groups (1.3 vs 1.2 and 23.4 vs 24.2 mL/s) and the postvoid residual urine volume decreased by 82.50% and 81.73% in the ThuLEP and HoLEP groups, respectively. The mean prostate-specific antigen decrease after HoLEP and ThuLEP was 30.43% and 43.36%, respectively. No urethral or bladder neck stricture were found in either group. Conclusion Both ThuLEP (70 W) and HoLEP (90 W) relieve lower urinary tract symptoms equally with high efficacy and safety. ThuLEP was statistically superior to HoLEP in blood loss and inferior to HoLEP in operation time, although the differences were clinically negligible. The mushroom technique could be adequate, without an additional mechanical tissue morcellator.
Abstract Context This is a short version of the European Association of Urology (EAU) guidelines on robotic and single-site surgery in urology, as created in 2013 by the EAU Guidelines Office Panel ...on Urological Technologies. Objective To evaluate current evidence regarding robotic and single-site surgery in urology and to provide clinical recommendations. Evidence acquisition A comprehensive online systematic search of the literature according to Cochrane recommendations was performed in July 2012, identifying data from 1990 to 2012 regarding robotic and single-site surgery in urology. Evidence synthesis There is a lack of high-quality data on both robotic and single-site surgery for most upper and lower urinary tract operations. Mature evidence including midterm follow-up data exists only for robot-assisted radical prostatectomy. In the absence of high-quality data, the guidelines panel's recommendations were based mostly on the review of low-level evidence and expert opinions. Conclusions Robot-assisted urologic surgery is an emerging and safe technology for most urologic operations. Further documentation including long-term oncologic and functional outcomes is deemed necessary before definite conclusions can be drawn regarding the superiority or not of robotic assistance compared with the conventional laparoscopic and open approaches. Laparoendoscopic single-site surgery is a novel laparoscopic technique providing a potentially superior cosmetic outcome over conventional laparoscopy. Nevertheless, further advantages offered by this technology are still under discussion and not yet proven. Due to the technically demanding character of the single-site approach, only experienced laparoscopic surgeons should attempt this technique in clinical settings. Patient summary This work represents the shortened version of the 2013 European Association of Urology guidelines on robotic and single-site surgery. The authors systematically evaluated published evidence in these fields and concluded that robotic assisted surgery is possible and safe for most urologic operations. Whilst laparoendoscopic single-site surgery is performed using the fewest incisions, the balance between risk and benefit is currently unclear. The evidence to support the conclusions in this guideline was generally poor, but best for robotic assisted radical prostatectomy. As such, these recommendations were based upon expert opinion, and further high-quality research is needed in this field.
Purpose
To perform a review on the latest evidence related to intrarenal pressures (IRPs) generated during upper-tract endourology, and present different tools to maintain decreased values, to ...decrease complication rates.
Methods
A literature search was performed using PubMed, restricted to original English-written articles, including animal, artificial model and human studies. Different keywords were: percutaneous nephrolithotomy, PCNL, ureteroscopy, URS, RIRS, irrigation flow, irrigation pressure, intrarenal pressure, intrapelvic pressure and renal-pelvic pressure.
Results
IRPs reported during retrograde intrarenal surgery (RIRS), PCNL, miniPCNL, and microPCNL range 40.8–199.35, 3–40.8, 10–45 and 15.37–41.21 cm H

Conclusions
Increased IRP values have been reported during RIRS and UASs constitute the most efficient tool for decreasing them. IRPs during mini-PCNL can be decreased utilizing the vacuum-cleaner and purging effects but might remain uncontrolled during micro- and ultra-mini PCNL. Intraluminal pharmacological treatment could play a role in IRP decrease, with isoproterenol being the most studied agent.
