Abstract
Standard treatment approaches for localized prostate cancer remain limited to active surveillance, radiotherapy, and radical prostatectomy. We present a case of transition zone prostate cancer that was treated with holmium laser enucleation of the prostate, a procedure that is normally reserved for the management of benign prostatic hyperplasia.

Abstract
OBJECTIVE To investigate the feasibility, safety and efficacy of holmium laser enucleation of the prostate (HoLEP) in the re-treatment setting (salvage HoLEP) and compare it to the primary HoLEP procedure that is commonly used for the treatment of benign prostate hyperplasia (BPH). MATERIALS AND METHODS Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, PubMed, Scopus, and Cochrane databases were systematically screened, from inception to 8 August 2022. Other potentially eligible studies were retrieved using the reference lists of the included studies. Retrospective and prospective studies, both comparative and non-comparative, were included. RESULTS A total of 12 studies met the inclusion criteria and were included in the final qualitative synthesis. One study was prospective comparative (non-randomised), seven studies were retrospective comparative, and four studies were retrospective non-comparative or case series. In total, 831 patients were treated with salvage HoLEP in the above studies. Previous intervention before salvage HoLEP ranged among studies. The most commonly performed was transurethral resection of the prostate. Intraoperative parameters of salvage HoLEP were comparable with those reported during primary HoLEP, while all postoperative outcomes were significantly improved after salvage HoLEP and were similar with those observed after primary HoLEP. No major complications were noted after salvage HoLEP according to Clavien-Dindo classification. CONCLUSIONS Salvage HoLEP after previous interventions for treating recurrent or residual BPH is a feasible, safe, and efficient procedure. Data presented in selected studies, along with the holmium laser's physical properties to resect more tissue and to dissect along the true anatomical plane of BPH, render HoLEP an ideal salvage treatment modality for recurrent or residual BPH symptoms.

Abstract
Introduction: Holmium laser enucleation of the prostate (HoLEP) is routinely performed with a 24F, 26F, or a 28F scope. Proponents of the larger scopes propose that a bigger sheath size allows for superior flow and visibility leading to a more efficient operation and better hemostasis. Those utilizing the smaller scopes suggest that the smaller sheath is less traumatic, resulting in lower stricture rates and temporary incontinence. We sought to compare outcomes of ambulatory HoLEP using the 24F and 28F laser scope. Materials and Methods: From May 2022 to March 2023, we randomized patients undergoing HoLEP (<200 cm3 in size) 1:1 to either a 24F or 28F scope. The primary outcome was differences in surgical duration between groups (minutes). Secondary outcomes included surgeon scope evaluation and postoperative patient results. Results: There was no difference in patient characteristics in those randomized to 28F (n = 76) vs 24F (n = 76) (p > 0.05) scopes. Procedural duration and efficiencies were not different between groups (all p > 0.05). The 28F scope was associated with improved surgeon-graded irrigation flow and visibility (p < 0.001). Patients treated with the 28F scope were more likely to achieve effective same-day trial of void (SDTOV) (28F 94.3% vs 24F 82.1%, p = 0.048) and have a shorter length of stay (LOS) (28F 7.0 vs 24F 11.9 hours, p = 0.014), however, rates of same-day discharge (SDD) were not statistically different (28F 87.8% vs 24F 78.4%, p = 0.126). There was no difference between the cohorts in rates of 90-day emergency room presentations, re-admissions, complications, or functional ouctomes (p > 0.05). Conclusions: We identified no clear advantage of scope size with regard to intraoperative or postoperative outcomes at 3-month follow-up due to scope size. However, if SDD is part of your postoperative pathway, the 28F scope may shorten LOS and increase rates of effective SDTOV. Clinicaltrials.gov: NCT05308017.

Abstract
BACKGROUND Central airway stenosis (CAS) in infants is characterized by dysphonia, dyspnea, cyanosis, repeated apnea, and infection. This case series study aimed to evaluate the safety and efficacy of holmium laser, cryoablation and budesonide inhalation in treating infants with severe CAS. METHODS This retrospective study reviewed medical records data of 28 infants with severe CAS who underwent holmium laser treatment with cryoablation and/or balloon dilatation and budesonide inhalation therapy at Shanghai Children's Medical Center between June 2014 and May 2020. Outcomes were defined as treatment success when the stenotic area was <25% for the normal age group with stable reopening diameter at one-year follow-up. RESULTS Patients' mean age was 12.8 ± 8.8 months and 17 (60%) were male. Sixteen cases had web-like stenosis and 12 had scar contracture stenosis. Among 16 patients with web-like stenosis, 8 (50%) underwent balloon dilation with cryotherapy and 8 (50%) underwent balloon dilation only; treatment success was achieved in 10 (62.5%) cases and after revised treatments in 5 (31.25%) cases. Among 12 patients with scar contracture stenosis, 6 (50%) underwent balloon dilation with cryotherapy, 4 (33.3%) underwent cryotherapy and 2 (16.7%) underwent balloon dilation only; treatment success was achieved in 3 (23.1%) cases and after 1-4 revised treatments in 8 (61.5%) cases. Symptoms of the 2 unsuccessful (7.1%) cases were relieved after tracheal stent insertion. Neither severe adverse events nor complications were observed during follow-up. CONCLUSION Holmium laser with cryoablation followed by budesonide inhalation therapy safely and effectively cleans stenotic tissues and maintains airway reopening. Balloon dilation after holmium laser is recommended for treating web-like stenosis.

Abstract
Purpose This study aimed to evaluate the efficacy and safety of same-session flexible ureteroscopy (fURS) for the treatment of bilateral upper urinary tract stones and to examine the influence of stone load on the outcome of same-session fURS, stratifying by total diameter of stones (TDS) ≤30 mm vs. >30 mm. Patients and methods We retrospectively reviewed all cases of same-session fURS performed for bilateral upper urinary tract stones at four institutions between January 2017 and September 2020. All patients were divided into two groups based on TDS, ≤30 mm and >30 mm. Data on patient demographics, stone characteristics, surgical results, and complications were collected and analyzed for differences between the two groups. Stone-free rate (SFR) was defined as patients endoscopically stone-free or with radiological fragments <2 mm of each renal unit. Results A total of 121 patients with bilateral upper urinary tract stones underwent same-session fURS, consisting of 73 patients in the TDS ≤ 30 mm group and 48 patients in the TDS > 30 mm group. The mean bilateral stone size was 28.2 ± 12.2 mm (range: 9.1-38.4 mm), with a mean operating time of 97.1 ± 39.6 min (range: 19-220 min). The SFR was 54.5% after the first fURS, and SFR increased to 97.5% after re-fURS for residual stones. The operation time for the TDS > 30 mm group was longer than that of the TDS ≤ 30 mm group (85.1 ± 36.5 vs. 115.4 ± 37.4 min, p < 0.001). The SFR after the first fURS was significantly lower in the TDS > 30 mm group than in the TDS ≤ 30 mm group (25.0% vs. 73.9%, p < 0.001). Although there was no statistically significant difference in overall SFR between the two groups (93.7% vs. 100%, p = 0.060), the rate of re-fURS for residual stones was higher in the TDS > 30 mm group than in the TDS ≤ 30 mm group (75% vs. 26%, p < 0.001). There were no significant differences in length of hospital stay (LOS) (2.2 ± 0.7 vs. 2.3 ± 1.0, p = 0.329) or complication rate (10.9% vs. 14.6%, p = 0.582) between the two groups. Conclusion The results suggested that same-session fURS can be effectively performed with a low complication rate. A higher SFR after the first fURS can be achieved in the case of bilateral upper urinary tract stones with TDS ≤ 30 mm, and priority should be given to same-session fURS.

Abstract
Advances in laser technology and surgical telescopic systems have propelled retrograde intrarenal surgery (RIRS) to the forefront as a viable alternative to percutaneous nephrolithotomy (PCNL). Currently, RIRS is being increasingly utilized as a treatment option, even for kidney stones larger than 2 cm. In this narrative review, we aimed to take a snapshot of current practice in renal stone treatment and the latest technological and technical developments and to evaluate the efficacy of RIRS in larger renal stones. With low complication rates and acceptable stone-free rates, RIRS offers patients a less invasive option with favorable outcomes. There are insufficient data comparing PCNL with RIRS using a new-generation high-power laser and suctioning ureteral access sheath (UAS). Further studies with novel lasers and UAS could provide superiority in terms of RIRS. It is crucial to take into account various patient-specific considerations, such as stone location and burden, when deciding on the appropriate treatment approach.

Abstract
INTRODUCTION The development and implementation in clinical practice of a 3rd generation thulium fiber laser with the possibility of computer control (modulation) of the shape, amplitude and pulse repetition rate opens up new possibilities for thulium fiber laser lithotripsy. AIM To carry out a comparative study of the efficacy and safety of thulium fiber laser lithotripsy using a of the 2nd (FiberLase U3) and 3rd generation devices (FiberLase U-MAX). MATERIALS AND METHODS A total of 218 patients with solitary ureteral stones, who underwent to ureteroscopy with lithotripsy using 2nd and 3rd generation thulium fiber lasers (IRE-Polus, Russia) from January 2020 to May 2022 with the same peak power (500 W), laser settings of 1 joule, 10 Hz and with a laser fiber diameter of 365 m, were included in the prospective study. For lithotripsy using FiberLase U-MAX laser a new original modulated pulse, which was found and optimized in a preclinical study, was used. Depending on the laser, the patients were divided into 2 groups. In 111 patients, stone fragmentation was performed on FiberLase U3 (2nd generation), while 107 patients were undergone to lithotripsy on a new laser device FiberLase U-MAX (3rd generation). Stone size ranged from 6 mm to 28 mm (11+/-4 mm). The duration of procedure and lithotripsy, the quality of the endoscopic picture during fragmentation (from 0 to 3 points, 0-bad, 3-excellent), the frequency of retrograde migration of stones, as well as damage to ureteral mucosa (of 1-3 degrees) were evaluated. RESULTS The time of lithotripsy was significantly lower in the group 2 than in the group 1 (12.3+/-4.6 vs. 24.7+/-6.2 min; p<0.05). The average quality of the endoscopic picture was significantly better in the group 2 (2.5+/-0.4 vs. 1.8+/-0.2 points; p<0.05). Clinically significant retrograde migration of stone or its fragments (the need for additional ESWL, flexible ureteroscopy) was noted in 16% vs. 8% of patients in group 1 and 2, respectively (p<0.05). Damage to ureteral mucosa of the 1st and 2nd degree due to laser exposure in the group 1 was noted in 24 (22%) and 8 (7%) cases, compared to 21 (20%) and 7 (7%) cases in group 2, respectively. Stone-free state was 84% in group 1 and 92% in group 2. CONCLUSION Modulation of the laser pulse shape allowed to improve endoscopic visibility, increase the speed of lithotripsy, reduce the frequency of retrograde stone migration without increasing the trauma to ureteral mucosa.

Abstract
Pseudoaneurysms of the renal arteries are caused by focal rupture or perforation of the arterial wall, resulting in local bleeding. Such pseudoaneurysms can be observed in conditions such as nodular polyarteritis, penetrating or closed renal injury, and medically induced injuries (such as renal puncture biopsy, percutaneous nephrostomy, or partial nephrectomy). Flexible ureteroscopy (FURS) is performed entirely through the urethra to prevent potentially severe kidney damage. Because of this, almost no renal parenchymal hemorrhage occurs after FURS laser lithotripsy. Only four cases had been documented in the literature as of December 2022. In this report, we describe a 53-year-old man with a history of recurrent kidney stones who underwent FURS laser lithotripsy for bilateral kidney stones. The procedure was smoothly performed, and no active bleeding occurred. However, the patient developed recurrent macroscopic hematuria after discharge from the hospital, and renal angiography revealed a pseudoaneurysm in the distal right kidney. The pseudoaneurysm was treated with selective arterial embolization. Serious complications of FURS surgery are rare, particularly the formation of pseudoaneurysms. We report the present case to bring this potential complication to the attention of urologists.

Abstract
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.

Abstract
OBJECTIVE By comparing with rigid ureteroscopy (r-URS), we explored the application value of flexible holmium laser sheath combined with r-URS in treating impacted upper ureteral stones. We also verified its effectiveness, safety and economy and investigated its application prospects at community or primary hospitals. METHODS From December 2018 to November 2021, 158 patients with impacted upper ureteral stones were selected from Yongchuan Hospital of Chongqing Medical University. Seventy-five patients in the control group were treated with r-URS, and 83 patients in the experimental group were treated with r-URS combined with a flexible holmium laser sheath if necessary. The operation time, postoperative hospital stay, hospitalization expenses, stone clearance rate after r-URS, auxiliary extracorporeal shock wave lithotripsy (ESWL) ratio, auxiliary flexible ureteroscope, the incidence of postoperative complications and the stone clearance rate after one month were observed. RESULTS The postoperative hospital stay, stone clearance rate after r-URS, the ratio of auxiliary ESWL, the ratio of the auxiliary flexible ureteroscope, and total hospitalization expenses in the experimental group were significantly less than those in the control group (p < 0.05). There was no significant difference in operation time, postoperative complications, and stone clearance rate after one month between the two groups (p > 0.05). CONCLUSIONS r-URS combined with flexible holmium laser sheath in treating impacted upper ureteral stones can improve the stone clearance rate and reduce hospitalization expenses. Therefore, it has a certain application value in community or primary hospitals.

Abstract
As a common clinical emergence, esophageal foreign body can lead to esophageal perforation followed by severe complications including aortic injury, mediastinal abscess and airway obstruction, leading to a high rate of mortality. Therefore, fast and effective diagnosis and treatment are of great necessity. In this case, holmium laser-assisted gastroscopy was adopted to remove the foreign body incarcerated in the esophagus, allowing patients to avoid traumatic and costly surgeries. It is a supplement to traditional methods of foreign body removal. The new combination tried in this report can bring development and innovation inspiration to the development of endoscopic technology.

Abstract
Diseases of the nasal cavity and paranasal sinuses lead to the development of clinical symptoms, among which difficulty in nasal breathing is among the most common complaints of patients in the practice of otorhinolaryngologists. To prevent the development of synechiae of the nasal cavity in surgery, the following principles are defined: 1) to reduce tissue injury, which is achieved by using modern equipment (endoscopic, laser, radio frequency, etc.); 2) to create a barrier between nearby areas of the nasal mucosa by introducing various intranasal splints; 3) to improve the process of tissue regeneration with the help of medicines (regenerants, reparants, etc.). Currently, there is no single approach to the surgical treatment of synechiae of the nasal cavity. The high frequency of postoperative relapses indicates the need to develop effective methods for the prevention of synechiae of the nasal cavity. The choice of surgical tactics is usually carried out taking into account the localization and extent of synechiae of the nasal cavity. All known methods of surgical treatment, depending on the instruments used for excision of synechiae of the nasal cavity, can be conditionally divided into cold and hot. The Sverzhevsky Research Clinical Institute of Otorhinolaryngology has developed a method of complex treatment and prevention of synechiae of the nasal cavity using laser technologies, silicone splints and a hydrogel material based on sodium alginate with derinate.

Abstract
Purpose: This study aimed to compare different laser systems for the enucleation of benign prostate hyperplasia. Methods: Randomized controlled trials (RCTs) on different lasers for prostate enucleation were searched from PubMed, Embase, and CNKI databases. Pairwise and network meta-analyis (NMA) were performed to analyze the outcome regarding surgery time, complications, short-term postvoid residual (PVR), long-term PVR, and short-term international prostate symptom score (IPSS), long-term IPSS, short-term maximum urine flow rate (Qmax), and long-term Qmax. RevMan software was used for paired meta-analysis. Considering the variance uncertainty caused by the different source regions of RCTs and the different primary conditions of surgeons and patients, this study uses Bayesian NMA conducted with ADDIS software to compare different treatment methods indirectly. Node-splitting analysis was used to test inconsistency for closed-loop indirect comparison. Results: Nine studies were included in this study, involving four types of lasers: diode laser, holmium laser, thulium laser, and greenlight laser. In safety paired meta-analysis, holmium laser could bring more complication risk than thulium laser (odds ratio: 2.70, 95% confidential interval [CI]: 1.79-4.00, p < 0.001), and no other significant result was detected. In the efficacy comparisons, holmium laser could offer better postoperative long-term PVR (standardized mean difference [SMD]: -0.35, 95%CI: -0.62, -0.09, p = 0.011), better postoperative long-term IPSS (SMD: -0.30, 95%CI: -0.57, -0.04, p = 0.011), better postoperative short-term Qmax (SMD: 0.44, 95%CI: 0.17, 0.70, p = 0.001) compared with greenlight laser. According to the results of NMA, greenlight laser may bring more complication risks when applied to prostate enucleation than the other three lasers. Thulium laser may be the recommended laser system for prostate enucleation. Conclusion: Thulium laser may be the recommended laser system since it can bring less complication risk with comparable efficacy. More RCTs are still needed to validate this study.

Abstract
INTRODUCTION During in situ lower pole laser lithotripsy, the dependent location may result in increased challenge fragmenting stones and a risk for stone regrowth if residual fragments remain. The purpose of this study was to compare the thulium fiber laser (TFL) with the holmium laser (HL) for in situ lower pole lithotripsy. MATERIALS AND METHODS In a 3D printed kidney benchtop model, sixty 1 cm BegoStones were placed in the lower pole and fragmented in situ until fragments passed through a 2 x 2 mm mesh. Laser lithotripsy was performed using twelve energy, frequency and fiber size combinations and residual fragments were compared. In addition, laser fiber diameters and subsequent ureteroscope deflections and flow rates were compared between fibers. RESULTS The TFL resulted in decreased residual fragments compared to the HL (11% vs. 17%, p < 0.001) and the three settings with least residual fragments were all TFL. Compared to the 150 µm TFL (265° deflection), there was a loss of 9° and 34° in the 200 µm TFL and 272 µm HL fibers, respectively. The measured fiber sizes were greater than manufacturer specified fiber size in every instance. Irrigation rates inversely correlated with fiber size. CONCLUSION The TFL resulted in 35% less residual stone fragments, up to 34° additional deflection, and an increased irrigation rate when compared to the HL. Optimal fragmentation settings are identified to further improve lower pole lithotripsy. The combination of reduced residual fragments, improved deflection, and better flow rates make the TFL advantageous for in situ lower pole lithotripsy.

Abstract
BACKGROUND Anticipating the total laser energy (TLE) of Holmium YAG laser required for ureteroscopic (URS) lithotripsy is essential to guide urologists in selecting the optimal fiber size. This study aimed at evaluating the relationship between stone size and stone attenuation measured by HU as predictors for the TLE during the procedure. METHODS We conducted an observational prospective cohort study of patients undergoing URS lithotripsy at the Urology department of Ain Shams University Hospitals from September 2018 to September 2019 with the use of a holmium YAG laser as the lithotripsy method. Patients' demographic and clinical characteristics, stone location, stone size, stone attenuation measured by HU from the non-contrast CT, TLE, and procedure time were recorded. Data were analyzed using Jamovi software (version 2.0 for macOS). RESULTS Forty patients were included in the study (22 males and 18 females) with a mean age of 57.8 years. The mean stone size was 9.8 mm3, the mean HU was 858.8 units, and the mean TLE was 3.5 KJ. Both stone size and stone attenuation measured by HU were positively correlated with TLE (r = 0.81 and 0.84, respectively; p < 0.001 for both). Further, regression analysis showed that both variables could significantly predict the TLE (ß = 0.001 and 0.71, respectively). CONCLUSIONS Both stone attenuation, as measured by HU, and stone size positively correlate with TLE required for URS lithotripsy. Therefore, both HU and stone size can predict the TLE, which will be helpful to guide the urologist in selecting the optimal fiber size for the procedure.

Abstract
Introduction Retrograde ureteroscopy with holmium laser lithotripsy (HLL) is a standard treatment for urolithiasis. Moses technology has been shown to improve fragmentation efficiency in vitro; however, it is still unclear how it performs clinically compared to standard HLL. We performed a systematic review and meta-analysis evaluating the differences in efficiency and outcomes between Moses mode and standard HLL. Material and methods We searched the MEDLINE, EMBASE, and CENTRAL databases for randomized clinical trials and cohort studies comparing Moses mode and standard HLL in adults with urolithiasis. Outcomes of interest included operative (operation, fragmentation, and lasing times; total energy used; and ablation speed) and perioperative parameters (stone-free rate and overall complication rate). Results The search identified six studies eligible for analysis. Compared to standard HLL, Moses was associated with significantly shorter average lasing time (mean difference [MD] -0.95, 95% confidence interval [CI] -1.22 to -0.69 minutes), faster stone ablation speed (MD 30.45, 95% CI 11.56-49.33 mm3/min), and higher energy used (MD 1.04, 95% CI 0.33-1.76 kJ). Moses and standard HLL were not significantly different in terms of operation (MD -9.89, 95% CI -25.14 to 5.37 minutes) and fragmentation times (MD -1.71, 95% CI -11.81 to 8.38 minutes), as well as stone-free (odds ratio [OR] 1.04, 95% CI 0.73-1.49) and overall complication rates (OR 0.68, 95% CI 0.39-1.17). Conclusions While perioperative outcomes were equivalent between Moses and standard HLL, Moses was associated with faster lasing time and stone ablation speeds at the expense of higher energy usage.

Abstract
INTRODUCTION Hem-o-Lok® clips are widely used in robot-assisted radical prostatectomy because of their ease of application and secure clamping. Although there have been some reports of their migration into the urinary tract, this usually occurs a few months after robot-assisted radical prostatectomy. Late-onset cases of Hem-o-Lok® clip migration, that is, after more than 1 year, are rare. CASE PRESENTATIONS We report three cases of delayed endourethral Hem-o-Lok® clip migration more than 2 years after robot-assisted radical prostatectomy. The Hem-o-Lok® clips were almost completely endoluminal, and were attached at one end to the vesicourethral anastomosis. We successfully removed them via transurethral surgery using a holmium laser. CONCLUSION This case series describes late-onset Hem-o-Lok® clip migration into the bladder more than 1 year after robot-assisted radical prostatectomy. Transurethral holmium laser surgery was very effective for Hem-o-Lok® clip removal. To avoid involvement of Hem-o-Lok® clips in the vesicourethral anastomosis, appropriate resection at the time of bladder neck transection is important.

Abstract
OBJECTIVE This study aims to evaluate the overall efficacy and safety between holmium laser enucleation of the prostate (HoLEP) and bipolar transurethral enucleation of the prostate (B-TUEP) for the treatment of benign prostatic hyperplasia (BPH). METHOD We systematically searched electronic databases (PubMed, Scopus, Web of Science, and Cochrane Library) to identify eligible comparative studies as of July 2021. The parameters including perioperative results, complications, and functional outcomes were evaluated. RevMan version 5.4 was used for the analysis. RESULTS A total of 10 studies involving 1725 patients were included. HoLEP had lower operative time (p = .03), shorter catheterization time (p = .007), lower bladder irrigation time (p = .01), and higher enucleation weight (p = .01) compared with B-TUEP. However, there were no significant differences between the techniques regarding the length of stay (LOS), hemoglobin drop, transfusion rates, and complications. Furthermore, no significant differences were also observed in postoperative functional outcomes at 1, 3, 6, 12, or 24 months. CONCLUSIONS HoLEP has more advantages in perioperative parameters compared with B-TUEP, but no significant differences are found regarding functional outcomes and complications. Large-scale studies with long-term follow-up are required to compare the outcomes of these two techniques.

Abstract
OBJECTIVES To compare the mid-term safety and efficacy of holmium laser enucleation of the prostate versus bipolar transurethral resection of the prostate in the management of large-volume benign prostatic hyperplasia. METHODS From December 2016 to March 2018, patients with benign prostatic hyperplasia (≥80 cc) were randomized (block randomization, computer-generated random list) to holmium laser enucleation of the prostate (57 patients) or bipolar transurethral resection of the prostate (55 patients). Patients were excluded if they had an International Prostate Symptom Score <13, a maximum urinary flow rate >15 mL/s or presence of prostate cancer, bladder stone, urethral stricture, neurogenic bladder, or previous prostate surgery. The primary outcome was hemoglobin loss. The analysis was intention-to-treat. Postoperative findings (36 months) were compared to baseline characteristics. Univariate and logistic regression analyses were performed for risk factors predicting hemoglobin loss or operative time in all patients. RESULTS There was no significant difference in baseline characteristics between the two groups. Holmium laser enucleation of the prostate was associated with significantly better operative time (P = 0.019), operative efficiency (P < 0.001), hemoglobin loss (P < 0.001), catheterization duration (P < 0.001) and hospital stay (P < 0.001) compared to bipolar transurethral resection of prostate. Both procedures were safe, with no significant difference in total complications (P = 0.128). Blood transfusion (P = 0.026) and capsular perforation (P = 0.239) were reported only in the bipolar transurethral resection of the prostate group. There was no significant difference in rates of urinary tract infections (P = 0.714), urethral strictures (P = 0.359), or transient stress incontinence (P = 0.717). At the last follow-up (3 years), holmium laser enucleation of the prostate was associated with significantly better International Prostate Symptom Scores, prostate-specific antigen levels and maximum urinary flow rates compared to bipolar transurethral resection of the prostate (P < 0.05). In logistic regression analyses, prostate size and bipolar transurethral resection of the prostate were associated with significantly greater hemoglobin loss, whereas prostate size, capsular perforation, and bipolar transurethral resection of the prostate were associated with significantly longer operative time. CONCLUSION Holmium laser enucleation of the prostate and bipolar transurethral resection of the prostate are effective and safe for the management of moderate-to-severe lower urinary tract symptoms attributable to large-volume benign prostatic hyperplasia (≥80 cc). However, if both techniques are available, holmium laser enucleation of the prostate is preferred due its better efficacy and safety profile.

Abstract
Objective The present study aimed to observe and discuss the effectiveness and safety of the UreTron single-probe ultrasonic intracorporeal lithotripter in ureteroscopic lithotripsy. Methods The clinical data of patients with unilateral solitary ureteral calculi treated with ureteroscopic lithotripsy who were hospitalized at the Department of Urology (West District) of Beijing Chaoyang Hospital between March 2016 and August 2020 were selected for retrospective analysis. The patients were divided into the UreTron group (group U) and holmium laser group (group H) according to the lithotripsy method adopted. The operation duration, length of hospital stay, stone clearance rate, proportion of patients requiring flexible ureteroscopy-assisted lithotripsy, and complications were compared between the groups. Results There was no statistical difference between the groups in terms of the general characteristics, operation duration, or length of hospital stay (P > 0.05). Regarding the stone clearance rate (group U=93.5%; group H=75%), proportion of patients requiring flexible ureteroscopy-assisted lithotripsy (group U=6.5%; group H=27.8%), and incidence of surgical complications (group U=1 case; group H=9 cases), group U was superior to group H, and the differences between the groups were statistically significant (P < 0.05). However, the differences in other complications (cardiocerebral complications and lower extremity thrombosis) were not statistically significant between the groups (P > 0.05). Conclusion The UreTron system is a new lithotripsy apparatus that is safe and effective for ureteroscopic lithotripsy and has certain advantages in terms of the stone clearance rate, proportion of patients requiring flexible ureteroscopy-assisted lithotripsy, and surgical complications, making it worthy of clinical application.

Abstract
Thirty-three years ago, pulsed lasers marked the beginning of a new era in endoscopic lithotripsy, and the one that was highlighted because of its potential was the Holmium: YAG laser, which became and still is the gold standard in endourology. Recently, a new laser technology has been accepted for clinical use in lithotripsy: the thulium fiber laser (TFL), showing appealing characteristics not seen before in several preclinical studies. A review of the literature was performed and all relevant in vitro studies and clinical trials until April 2021 were selected. The search came back with 27 clinical experiences (7 full-text clinical trials and 20 peer-reviewed abstracts) and 33 laboratory studies (18 full-text articles and 15 peer-reviewed abstracts). The clinical experiences confirmed the clinical safety of using the wide parameter range of the TFL. This technology demonstrated the performance at a higher ablation speed, the higher ablation efficiency, and the better dust quality of the TFL, as well as reduced stone retropulsion, thus helping to maintain an optimal visibility. No thermal or radiation damage was found. Given the current evidence, we may be facing the future gold standard laser in endoscopic lithotripsy.

Abstract
Introduction The aim of this study was to assess the short-term functional outcomes and the efficacy of hemostasis performed with holmium laser performed following prostatic hydroablation with the Aquabeam® system. Material and methods Between June 2019 and July 2020, 53 consecutive patients underwent Aquabeam® with our modified hemostasis approach with holmium laser. The following standard preoperative assessments were retrospectively recorded: prostate volume; International Prostate Symptom Score (IPSS) and Quality of Life (IPSS-QoL); uroflowmetry including Qmax and post void residual volume (PVR). Results Fifty-three patients consecutively underwent aquablation and holmium laser hemostasis. Median age at surgery, median prostate-specific antigen (PSA) and median prostate volume were 62 years (IQR: 57-66), 2.95 ng/ml (IQR: 1.6-4.8) and 55 ml (IQR: 43-65), respectively.Median operative time was 60 minutes (IQR: 40-80). Median catheterization time and length of hospital stay were 2 days (IQR: 1-3) for both parameters. The median hemoglobin decrease between the preoperative values and those assessed on the second day was equal to 1.25 g/dl (IQR: 0.7-1.85).Continence rate was 100% at catheter removal. Thirty-six patients (72%) reported anterograde ejaculation preservation. IPSS (6, 3-21) and Qmax (19, 9-26) changed dramatically between baseline and 3 months follow-up. Conclusions The combination of Aquabeam® and holmium laser energy for hemostasis is a safe, reproducible technique to relieve moderate lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH) while preserving ejaculation in younger and sexually active individuals. The short-term results showed a lower rate of complications; the encouraging functional results confirm that this can be a valid surgical approach for treatment of BPH.

Abstract
Family planning is a basic national policy in China. An intrauterine device (IUD)
is an important method of achieving family planning owing to its high safety,
low cost, and convenient use. The indwelling birth control ring has no obvious
adverse effects on the sexual life of women after the operation, and the process
is reversible. This ring can be removed for women who want to have children
again. There are approximately 100 million women with IUDs worldwide, with
approximately 80 million in China. This finding accounts for approximately 40%
of women of childbearing age in China. Although an IUD is safe, the invasive
operation inevitably leads to complications, such as pelvic infection, abnormal
menstruation, and damage to adjacent organs. Among them, ectopic bladder stone
formation is a rare complication, but several related cases have been reported.
We report four cases of heterotopia of an IUD and cystolithiasis, with diagnosis
based on the medical history, clinical manifestations, imaging, and cystoscopic
findings. The four patients with ectopic IUDs were treated with cystoscopy
combined with laparoscopy (or hysteroscopy). We describe the process of
diagnosis and treatment of our patients, and the related literature on an
ectopic IUD is reviewed.

Abstract
Laser disintegration of urinary stones is a cornerstone of urolithiasis treatment in the modern era. Despite the wide clinical use of stone lasers, basic and advanced technological achievements and developments are difficult to comprehend and interpret by the average urologist. A descriptive analysis of laser production and stone disintegration mechanisms was performed. We focused on physics of modern types of lithotripters, the construction of laser fibers, laser parameters, new modes, settings, and lithotripsy techniques. The main principle of laser emission remains the same since the first emitting laser was produced. Peak power density and short interaction time lead to photothermal effects responsible for stone disintegration. Modern lithotripters such as Holmium: YAG (low/high power, Moses technology) and thulium fiber laser show basic construction differences with the physical properties of the latter being superior, at least in in vitro studies. By adjusting lasing parameters, a wide spectrum of stone ablation from fragmentation to dusting can be achieved. New technology allows for the production of real dust. Knowledge of laser fiber construction and physical properties are useful in marketing and clinical use. Urologists should understand the physical and physiological background of the lasers used in their everyday practice for stone fragmentation.

Abstract
INTRODUCTION The length of the operation to remove urinary concernments has a marked effect on the occurrence of postoperative complications in the time of the postoperative patients in the hospital. A significant factor contributing to the increase in time is the clouding of the fragmentation region, which increases the operation time and the number of complications. PURPOSE to develop a method of reducing the time of additional costs in contact lithotripsy with a holmium laser in order to reduce the risk of postoperative complications. MATERIALS AND METHODS The paper presents the own results of in vivo measurements of time intervals spent on fragmentation of stone. Fragmentation of stones in kidney was carried out by a holmium lithotripter of Triple type with the help of semirigid and flexible ureteroscopes. In the case of severe clouding of the fragmentation region, the author s technique of percutaneous micro-drainage of the kidney was used. The evaluation of the duration of the fragmentation procedure is based on statistical processing of the obtained measurement data using Excell Data Analysis tools. RESULTS In the process of analysis of literary sources and results of own studies it was revealed that with increase in duration of contact laser lithotripsy the number of postoperative complications significantly increases. In order to reduce the time of transurethral contact holmium lithotripsy, the author s technique of percutaneous micro-drainage has been developed. By in vivo measurements and statistical processing of the data, it was found that by using the micro-drainage technique, the average additional washing time of the fragmentation region was reduced by an average of 4 times compared to the conventional technique. CONCLUSION By further washing the fragmentation region, it is possible to reduce the time of additional crushing costs by at least 4 times and reduce the number of postoperative complications.

Abstract
Purpose: To compare the efficacy and safety of plasma kinetic enucleation of the prostate (PKEP) with holmium laser enucleation of the prostate (HoLEP) for treatment of benign prostatic hyperplasia (BPH). Methods: A total of 160 patients with indications for the surgical treatment of BPH were randomly assigned to receive either PKEP or HoLEP prospectively. Baseline characteristics, perioperative data, and postoperative outcomes of the patients were recorded. One hundred twenty-six (78.75%) patients (PKEP 64 vs HoLEP 62) completed the 3-year follow-up assessment. Results: Patients in both groups had similar baseline characteristics. Compared with PKEP, HoLEP was associated with shorter operative time as well as take-out time, lower perioperative hemoglobin decrease, and shorter bladder irrigation time, catheterization time, and hospital stay time. PKEP was superior to HoLEP in terms of the noise of the machine and hospitalization expenses. There were no significant differences in enucleating time, resected weight, and serum sodium levels. Both groups achieved satisfactory results and maintained improvement from baseline in terms of maximum urinary flow rate (Qmax), International Prostatic Symptomatic Score, quality of life, and postvoid residual at 3-year follow-up, with no significant differences between the two procedures. Except for re-catheterization rate, postoperative data such as transrectal ultrasound volume, International Index of Erectile Function-5, and follow-up scores of the flexible cystourethroscopy results, as well as the acute and mid-to long-term complications after surgery, were statistically similar. Conclusion: The 3-year follow-up data of this randomized trial confirmed that both PKEP and HoLEP were effective and safe surgical procedures for the transurethral management of BPH. HoLEP presented certain advantages compared to PKEP, such as reduced operative duration, decreased risk of blood loss, and less bladder irrigation, hospital stay time, and re-catheterization rate, whereas PKEP had lower noise and no additional laser cost.

Abstract
OBJECTIVE Despite the acknowledgment that holmium laser enucleation of the prostate (HoLEP) is a safe, efficacious procedure with benefits over traditional treatments, it is not widely adopted. Its steep learning curve is considered responsible, and the new en bloc technique (EBT) aims to improve this. METHODS A retrospective analysis of 268 consecutive patients (215 lobe technique [LT] and 53 EBT) who underwent HoLEP between May 2016 and April 2020 was performed. Data were collected on patient demographics, prostate volume, enucleation time, prostatic weight, and length of stay. RESULTS There was no difference in mean prostate volume and enucleated prostatic weight between the LT and EBT (99.2 mL vs 98.5 mL, P = .95216, and 71.7 g vs 69.3 g, P = .92034, respectively). There was a reduction in mean enucleation time with the EBT to 37.7 minutes compared with 53.3 minutes (LT) (P < .00001). This translated to an improved operative efficiency of 1.84 g/min (EBT) compared to 1.33 g/min (LT) (P < .00001). The EBT demonstrated a continuous improvement in operative efficiency with increasing prostate size unlike the LT where efficiency plateaus. CONCLUSIONS The EBT for HoLEP demonstrates a significant improvement in operative efficiency which has the potential to reduce the surgeons' learning curve and lead to more widespread adoption.

Abstract
PURPOSE OF REVIEW Lasers have become a fundamental aspect of stone treatment. Although Holmium:Yttrium-Aluminum-garnet (Ho:YAG) laser is the current gold-standard in endoscopic laser lithotripsy, there is a lot of buzz around the new thulium fibre laser (TFL). We decided to evaluate the latest data to help create an objective and evidence-based opinion about this new technology and associated clinical outcomes. RECENT FINDINGS Sixty full-text articles and peer-reviewed abstract presentations were included in the qualitative synthesis of this systematic review performed over the last 2 years. Current super pulsed TFL machines are capable of achieving peak powers of 500W and emit very small pulse energies of 0.025 Joules going up to 6 Joules, and capable of frequency over 2000 Hz. This makes the TFL ablate twice as fast for fragmentation, 4 times as fast for dusting, more stone dust of finer size and less retropulsion compared to the Ho:YAG laser. Because of the smaller laser fibres with the TFL, future miniaturization of instruments is also possible. SUMMARY Based on the review, the TFL is a potential game-changer for kidney stone disease and has a promising role in the future. However larger multicentric prospective clinical studies with long-term follow-up are needed to establish the safety and efficacy of the TFL in endourology.

Abstract
Background: Straight catheters are usually used for clean intermittent catheterization (CIC). Patients perform CIC without much difficulty. Spontaneous knotting of catheter is rare in large bore straight catheters and female patients. Case Presentation: A 50-year old lady, case of neurogenic bladder on CIC inserted a 14F straight catheter, drained some urine but was unable to remove the catheter. She presented in emergency with retention of urine. Her X-ray and ultrasound examination revealed a knotted catheter. Conservative measures to remove the catheter such as forceful injection of radio-opaque contrast and passage of hydrophilic guidewire did not work. She was taken in the operating room. The knot was ablated using holmium laser through transurethral passage of an 8F ureteroscope. Conclusions: Spontaneous knotting of urethral catheter is rare in adults. It should be suspected whenever a straight catheter cannot be removed. Inserting excessive length of catheter is an important risk factor. Holmium laser is an excellent tool to cut the catheter in a least invasive way when conservative measures have failed.

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

Abstract
BACKGROUND Occlusive granulation tissue formation, as one of the most common sequelae of chronic foreign body aspiration, can cause tracheobronchial obstruction and delayed fixed airway stenosis necessitating interventions. The aim of this study was to explore the clinical efficacy and safety of interventional therapy via flexible bronchoscopy for treatment of granulation tissue related airway obstruction secondary to foreign body aspiration in children. METHOD Patients with long-term foreign body related granulation tissue were treated with flexible bronchoscopy therapeutic modalities, including forceps, cryotherapy, holmium laser, and balloon dilatation. Clinical efficacy was evaluated by clinical symptoms and endoscopic manifestations. RESULTS A total of eight patients with granulation tissue hyperplasia caused by foreign body in bronchus, with a median age of 29.5 (range, 18-54) months, underwent interventional therapy between January 2016 and December 2019. Four patients received forceps and CO2 cryotherapy and one patient required forceps only. The remaining three patients received holmium laser combined with CO2 cryotherapy, and one of them required additional balloon dilatation. Four cases required a second cryotherapy procedure, and one case received three cryotherapy procedures for extensive granulation tissue. The treatment efficacy was 100% without complications. CONCLUSION Interventional procedure via flexible bronchoscopy is a safe, reliable, and effective method in the management of tracheobronchial obstruction and stenosis caused by foreign body-related granulation tissue hyperplasia. It is worthy of clinical application.

Abstract
Background: Selective renal artery angioembolization is the first treatment option in case of significant bleeding after percutaneous nephrolithotomy. Migration of embolization material into the collecting system is extremely rare. The treatment of this condition is not standardized, but manual extraction, ultrasound fragmentation, and holmium laser lithotripsy have been described. Case presentation: We report the laser extraction of these coils in two patients at our center with two different approaches: retrograde intrarenal surgery (RIRS) and endoscopic combined intrarenal surgery (ECIRS). They were young male patients aged 25 and 29 years at the time of surgery, and they were 2-5 years postembolization when they presented to our center for symptoms such as hematuria and passage of small stone fragments. The first patient was managed solely with RIRS, whereas the second patient required ECIRS because of significant bleeding after coil removal, which necessitated hemostasis using a resectoscope. Conclusion: For patients who present with recurrent stones or other symptoms such as pain, hematuria, or flank pain, the diagnosis of migrated embolization coils should be considered. Management can be via the retrograde or percutaneous approach, but in the setting of significant amount of migrated coils or significant bleeding after their removal, percutaneous access may allow more definitive hemostasis.

Abstract
Background: Although the prostatic urethral stents are no longer used in the United States for treatment of prostatomegaly, urologists will encounter patients with complications of previously placed permanent prostatic stents. We report two cases of persistent bothersome lower urinary tract symptoms (LUTS) after prostatic stent placement treated with simultaneous holmium laser enucleation of prostate (HoLEP) with endoscopic removal of the prostatic urethral stent using high-power holmium laser. We also reviewed the literature regarding the removal of prostatic stents with holmium laser combined with surgical management of benign prostatic hyperplasia. Case Presentation: A 71-year-old man who presented with LUTS, recurrent gross hematuria, and urinary infection, which developed after placement of a prostatic stent 10 years prior for urinary retention secondary to prostatomegaly (80 g). He underwent combined HoLEP with endoscopic removal of the prostatic stent using 100 W holmium laser at a power setting of 2 J and 30 Hz. The surgical steps comprised fragmentation of the stent in situ by making incisions at 5, 7, and 12 o'clock positions followed by enucleation of the prostate. The stent was then separated from enucleated tissue in the urinary bladder. The remaining prostate adenoma was then morcellated and removed. The patient remained asymptomatic at 10-year follow-up. Another patient was 62-year-old man who developed recurrence of bothersome LUTS, 1 year after placement a prostatic stent for urinary retention. On investigation his prostate was 105 g and stent showed partial migration in the bladder with overlying calcification. HoLEP and stent removal was performed in a manner similar to the first patient. This patient also remained asymptomatic at a 1-year follow-up. Conclusion: Combined HoLEP with removal of a prostatic urethral stent using a high-power holmium laser is safe and effective with long-term durable outcome.

Abstract
The present study aimed to compare the efficacy and safety of a flexible ureteroscopic holmium laser incision with flexible ureteroscopic 1470-nm diode laser incision for the treatment of parapelvic renal cysts. The current study collected and analysing the clinical data of 90 independent renal cysts cases retrospectively, including 43 renal cysts cases that received holmium laser surgery (holmium laser group) and 47 renal cysts cases that received 1470-nm diode laser surgery (1470-nm diode laser group). Each group was divided into a thin-walled cyst subgroup and thick-walled cyst subgroup according to cyst wall thickness. Intracapsular hematoma was significantly lower in the 1470-nm diode laser group compared with the holmium laser group (0/47 vs. 4/43; P=0.048). The incision diameter in the 1470-nm diode laser group was significantly larger than the holmium laser group in the thick-walled parapelvic renal cysts subgroup [1.70(1.50,1.90) vs. 1.30(1.25,1.70) cm; P=0.007]. The renal cystic diameter of the two groups was markedly reduced one and six months after surgery. The difference was non-significant in the diameter of the renal cyst in the thin-walled cysts subgroups between the two laser groups 6 months after surgery (1.01±0.38 vs. 1.03±0.53 cm; P=0.454). However, the diameter of the renal cyst in the thick-walled cysts subgroup treated with the 1470-nm diode laser was significantly lower compared with the thick-walled cysts subgroup treated with the holmium laser 6 months after surgery (1.21±0.57 vs. 1.88±0.94 cm; P=0.002). The results demonstrated that the use of a 1470-nm diode laser or holmium laser surgery under a flexible ureteroscope is a safe and effective treatment for parapelvic renal cysts. For thick-walled parapelvic renal cysts, the 1470-nm diode laser appears to exhibit a lower postoperative recurrence rate and better long-term postoperative effects due to its improved haemostatic effect and larger intraoperative incision diameter.

Abstract
OBJECTIVE To evaluate the safety, efficacy and cost-effectiveness of holmium enucleation of the prostate and bipolar transurethral enucleation of the prostate. METHODS In our randomized controlled trial, 120 patients were allocated into two equal groups representing holmium enucleation of the prostate and bipolar enucleation of the prostate. Operative parameters were recorded according to operative, enucleation and resection time in addition to the intraoperative complications. Patients were followed up at 1, 3 and 12 months postoperative to assess the prostate size, post-voiding residual urine, International Prostate Symptom Score, peak urine flow rate and quality of life, and compared with the preoperative parameters. Cost analysis was evaluated for both procedures. RESULTS We evaluated 107 patients who finished our follow up and their data were analyzed. The prostate size was 135.2 ± 34.8 mL and 125 ± 26.9 mL for holmium enucleation of the prostate and bipolar enucleation of the prostate, respectively. Holmium enucleation of the prostate was associated with a shorter operative time of 83.43 ± 6.92 min compared with 94.7 ± 12.2 min in bipolar enucleation of the prostate groups. Holmium enucleation of the prostate was associated with an earlier catheter removal time and shorter hospital stay compared with bipolar enucleation of the prostate. Postoperative International Prostate Symptom Score, quality of life, post-voiding residual urine, peak urine flow rate, prostate-specific antigen and prostate volume reduction were comparable between both groups, and they both showed statistically significant improvement compared with their preoperative parameters. In the cost analysis, holmium enucleation of the prostate was more cost-effective than bipolar enucleation of the prostate. CONCLUSION Both holmium enucleation of the prostate and bipolar enucleation of the prostate are safe and effective in the surgical management of large prostatic adenomas. Holmium enucleation of the prostate has a shorter operative time and hospital stay with earlier catheter removal time, and is more cost-effective than bipolar enucleation of the prostate.

Abstract
Background: Laser endoureterotomy became a preferable choice for managing benign ureteral strictures. Ureteral stricture caused by bilharzias is characterized by focal destruction of ureteral musculature, ending by fibrosis, making it poor responder to endoureterotomy. There is no consensus about the ideal ureteral stent size after endoureterotomy. However, many researches recommend larger stents caliber (12-14F). We assess long-term efficacy of insertion of two ipsilateral Double-J stents vs single Double-J stent after laser endoureterotomy for bilharzial ureteral stricture. Materials and Methods: Within 4 years, 70 patients underwent retrograde laser endoureterotomy for bilharzial ureteral stricture (diagnosed by positive history of bilharziasis, positive serology test, and/or bilharzial cystoscopic finding). Patients with history of stone, urologic or pelvic surgery were excluded. Patients were randomized into two groups: the first group (35 patients) received ipsilateral two Double-J (7F each) postendoureterotomy, whereas the second group (35 patients) received one Double-J (7F). Double-Js were removed after 8 weeks. Follow-up was done regularly by clinical interpretation and imaging studies. Patients' characteristics, operative data, and postoperative outcomes (subjectively and objectively) were compared in both groups. Results: Sixty-three patients completed follow-up >18 months, mean follow-up 30 ± 4 months [19-41], and mean stricture length 1.4 ± 0.6 cm [0.5-3.0], with no statistical significance between both groups. Success proved by relief of symptoms and radiographic resolution of obstruction. The overall success rate was significantly better in 2-Double-J group than in 1-Double-J group (83.9% vs 53.1%) p = 0.009, and also for stricture >1.5 cm (85.7% vs 38.5%) p = 0.018, respectively. Conclusions: Insertion of two ipsilateral Double-J, after laser endoureterotomy for bilharzial ureteral stricture associated with long-term success rate better than insertion of 1-Double-J, especially for stricture segment >1.5 cm.

Abstract
To explore the safety and effectiveness of ureteroscopic holmium laser lithotripsy (UHLL) and ureteroscopic pneumatic lithotripsy (UPL) in the treatment of impacted ureteral calculi (IUC).Clinical data of 280 patients in our hospital from April 2016 to May 2019 were retrospectively collected and analyzed, including 136 cases of UHLL group and 144 cases of UPL group. The general clinical data, operation time, intraoperative bleeding volume, hospital stay, stone-free rate (SFR), and surgical complications were collected and analyzed in 2 group.Compared with UPL group, the operation time of UHLL group was significantly reduced (27.25 ± 8.39 vs 34.32 ± 10.57, P < .05), but the hospitalization cost was significantly increased (9.25 ± 0.75 vs 8.24 ± 0.51, P < .05). In terms of total SFR, the UHLL group was significantly higher than the UPL group (93.38% vs 83.33%, P = .011). For proximal IUC, compared with the UPL group, the SFR of the UHLL group was significantly increased (88.33% vs 70.31%, P = 0.005). For distal IUC, there was no significant difference in SFR (97.37% vs 93.75%, P = .638) between the UHLL group and UPL group. There were no significant differences in the complications of local mucosal injury, hematuria, febrile urinary tract infection, ureteral perforation, and urinary sepsis in the 2 groups (P > .05). However, the UHLL group was significantly lower in stone residual rate than the UPL group (6.61% vs 16.67%, P = .001).This study found that UHLL and UPL are safe and effective in the treatment of IUC, but UHLL has the advantages of shorter operation time and high SFR in the treatment of IUC.

Abstract
OBJECTIVES Problem bladder pain syndrome/interstitial cystitis (BPS/IC) is a heterogeneous disorder with variation in management worldwide. Phenotyping aims to personalize therapy and optimize outcomes. The most well-described phenotype is Hunner lesion disease (HLD). The prevalence of HLD and outcome of phenotype-directed management in the UK is not well-studied. We describe the management of a contemporary cohort of patients with BPS/IC in the UK. METHODS Retrospective analysis of all patients with BPS/IC from January 2015-November 2018. Outcomes of patients who underwent laser ablation to Hunner lesions were collected using the Global Response Assessment tool. RESULTS One hundred and sixty-three patients (mean age of 43 years [20-85]) were included. 78% were female and patients had experienced symptoms for an average 6 years (1-30) prior to specialist assessment. Eighty-three percent of patients had pelvic imaging (44% ultrasound, 42% magnetic resonance imaging and 14% computed tomography), and a relevant abnormality was found in five (4%). Twenty-two patients (14%) had HLD (International Society for the Study of BPS [ESSIC] 3), with a mean bladder capacity of 373 mL (175-650 mL); 77% were ESSIC C on histopathology. All patients with HLD underwent laser ablation, with 55% experiencing a moderate/marked improvement in symptoms, with a mean duration of effect of 10 months (3-36); 27% of patients had a repeat treatment. CONCLUSIONS The presence of HLD in patients with BPS/IC is not uncommon. Pelvic imaging rarely identifies any cause for pain and so cystoscopy under anesthesia is essential for accurate phenotyping. Phenotype-directed management with holmium laser ablation to Hunner lesions has good short-term efficacy in improving pain, but re-intervention is often required.

Abstract
Objectives To present the 12-month outcomes of ‘Top-Down’ holmium laser enucleation of the prostate (HoLEP). Patients and methods We retrospectively reviewed the charts of prospectively collected patients who underwent Top-Down HoLEP between 2017 and 2018. All cases were operated upon by a single urologist (H.E), using a 100-W holmium:YAG laser with a 550-μm laser fibre. We recorded the enucleation time, morcellation time, intraoperative, and postoperative complications. All patients had postoperative follow-up visits at 1, 3, 6 and 12 months. The evaluation included the International Prostate Symptom Score (IPSS), quality-of-life (QoL) assessment, measurement of maximum urinary flow rate (Qmax) and the post-void residual urine volume (PVR). Results A total of 60 consecutive patients were recruited. The median (range) prostatic volume, resected prostatic weight, and percentage of resected prostatic tissue were 124 (70–266) mL, 90 (44–242) g and 76 (46–97)%, respectively. The median (range) enucleation and morcellation times were 80 (25–200) and 14.5 (4–58) min, respectively. One patient had a simple bladder mucosal injury and another developed clot retention. At 3 months, three patients (5%) had stress urinary incontinence (SUI) and eight patients (13.3%) presented with urge UI (UUI). At the last follow-up visit, one patient (1.7%) presented with persistent SUI, while three patients (5%) presented with UUI. The IPSS and QoL significantly improved during the follow-up period (P = 0.045 and P = 0.04, respectively). Conclusion The results of the Top-Down technique are comparable to those of traditional HoLEP. However, the Top-Down technique may reduce the complexity, operating time, and SUI rates. Abbreviations BN: bladder neck; HoLEP: holmium laser enucleation of the prostate; PVR: post-void residual urine volume; Qmax: maximum urinary flow rate; QoL: quality of life; TOV: trial of voiding; (S)(U)UI: (stress) (urge) urinary incontinence

Abstract
The elderly population has been increasing significantly in our century. In our study, it was aimed to analyze the treatment results of elderly male patients who underwent holmium laser lithotripsy (HLL) for urethral stones under local anesthesia. We evaluated a total of 31 male patients, aged ≥65 years, diagnosed with urethral stones and treated with HLL under local anesthesia. We noted the demographic data and visual pain scores (VAS) of the patients and the duration of the operation and hospital stay. Our analysis involved both the success rates of the surgical procedure and the complication rates according to the modified Clavien classification. In addition. we determined the patients’ preoperative clinical status using the Charlson comorbidity index (CCI). The mean age of the patients was 71.65 ± 8.19 years. Acute urinary retention was the most common complaint (45.2%). Their mean scores were 7.68 ± 2.53 according to CCI. The average operation time was 15.48 ± 5.22 min and the VAS was 2.03 ± 1.08. All patients were stone-free and there was a marked improvement in their symptoms None of them stayed in the hospital for more than one day. We did not observe any Grade 3 or higher complications. In light of the data obtained in our study, we concluded that HLL is an effective and reliable method to treat urethral stones under local anesthesia in elderly male patients.

Abstract
Objective: To compare regular and Moses modes of holmium laser lithotripsy during ureteroscopy in terms of fragmentation/pulverization and procedural times in addition to perioperative complications. Patients and Methods: After obtaining ethics approval, a prospective double-blinded randomized trial was conducted for patients undergoing holmium laser lithotripsy during retrograde ureteroscopy. Patients were randomly assigned to either regular or Moses modes. Patients and surgeons were blinded to the laser mode. Lumenis 120W generator with 200 Moses D/F/L fibers were used. Demographic data, stone parameters, perioperative complications, and success rates were compared. The degree of stone retropulsion was graded on a Likert scale from 0-no retropulsion to 3-maximum retropulsion. Results: A total of 72 patients were included in the study (36 per arm). Both groups were comparable in terms of age and preoperative stone size (1.4 cm vs 1.7 cm, p > 0.05). When compared with the regular mode, Moses mode was associated with significantly lower fragmentation/pulverization time (21.1 minutes vs 14.2 minutes; p = 0.03) and procedural time (50.9 minutes vs 41.1 minutes, p = 0.03). However, there were no significant differences in terms of lasing time (7.4 minutes vs 6.1 minutes, p > 0.05) and total energy applied to the stones (11.1 kJ vs 10.8 kJ, p > 0.05). Moses mode was associated with significantly less retropulsion (mean grade was 1.0 vs 0.5, p = 0.01). There were no significant differences between both modes in terms of intraoperative complications (11.1% vs 8.3%, p > 0.05), with one patient requiring endoureterotomy for stricture in the Moses group. Success rate at the end of 3 months was comparable between both groups (83.3% vs 88.4%, p > 0.05). Conclusion: Moses technology was associated with significantly lower fragmentation/pulverization and procedural times. The reduced fragmentation/pulverization time seen using Moses technology could be explained by the significantly lower retropulsion of stones during laser lithotripsy.

Abstract
BACKGROUND endoscopic enucleation is a conventional minimally invasive method of surgical treatment for large prostates. AIM The aim of the study was to analyze preoperative, intraoperative, immediate postoperative outcomes and 12-month functional results of endoscopic enucleation of the prostate. MATERIALS AND METHODS a total of 120 endoscopic enucleations were performed in the Department of Urology, City Clinical Hospital named after D.D. Pletnev in 2016-2017. Bipolar electroenucleation was performed in 63 cases, while laser enucleation was done in 57 patients (28 holmium and 29 thulium). Three-lobe, two-lobe and en-block electroenucleation was performed in 23, 24 and 16 patients, respectively. The technical advantages of laser enucleation included lesser need for mechanical traction during enucleation of the adenoma from the prostatic capsule and the predominant use of two-lobe technique (33 cases). En-block laser enucleation was done in 7 patients, while three-lobe technique was used in 17 patients. Both groups were comparable in terms of I-PSS, QoL, prostate volume, maximum urination rate, and residual urine volume. RESULTS weight of the removed adenoma after electroenucleation was 105+/-24 g and 98+/-18 g after laser enucleation; the operation time was 118+/-10 and 132+/-25 min, duration of the catheterization 48+/-16 and 51+/-10 h, length of stay 3.6+/-1.2 and 3.8+/-1.3 days, respectively. Closed prostate perforation more often occurred after electrosurgical enucleation (6 vs. 1). There were no significant differences in the outcomes in both groups one year after the surgery. After removal of the urethral catheter, incontinence developed in 9% (6/63 and 5/57, respectively) of cases. During the period from 6 to 12 months, urinary incontinence persisted only in one patient, who subsequently was underwent to injection therapy with a partially positive effect. All 22 patients with urinary disturbances that occurred after enucleation had a short distance from the top of the verumontanum to the external sphincter (less than 1.5 cm; risk ratio (RR) = 3.5) and intravesical protrusion of more than 1 cm (RR=2.1). CONCLUSION endoscopic bipolar and laser enucleation is an effective and safe treatment method for large BPH. It should be noted that postoperatively there was an increased frequency of irritative symptoms, which disappeared by 6 months.

Abstract
OBJECTIVE: The present study reports a retrospective evaluation of the first Holmium laser prostate enucleation (HoLEP) cases and their results in our clinic. METHODS: Twenty four patients who underwent HoLEP surgery between April 2017 and November 2017 were evaluated for demographic characteristics, duration of operation, amount of hemorrhage, amount of energy used, tissue weight removed, catheterization time and complications. IPSS and uroflowmetry results were compared before and after the surgery. RESULTS: Patients with hemoglobin, IPSS, uroflowmetry, and voiding speeds (Qmean, Qmax) were compared before and after the surgery. There was a significant difference in IPSS, Qmean and hemoglobin values but not in Qmax, statistically. Our complications rates were correlated with the literature. CONCLUSION: HoLEP stands out as a surgical method that can be applied with high confidence in the treatment of benign prostatic hyperplasia and it has similar functional results to gold standard surgeries, causes fewer complications, improves patient comfort due to short catheterization and hospitalization and is more advantageous regarding cost.

Abstract
In the conditions of the experiment the peculiarities of thermal influence of Ho:YAG on biological tissue in the ablation mode were studied. In the experiment we used: surgical laser system LUMENIS VersaPulse PowerSuite 20, universal thermal imaging camera FLIR SC7000. The biological object (turkey meat) was remotely, at a distance of 5 mm, affected by a Holmium laser (E = 0.9 J and R = 12 Hz) for 6 seconds. The maximum temperature (Tmax, °C) in the ablation zone was measured in real time. As a result, it was found that laser ablation of a biological object is characterized by thermal effects, which largely depend on the state of irradiated tissue: the temperature of the irradiated object rises to critical values equal to 100.07-111.24 ° C, after which the surface layer of biological tissue is charred, and the process of laser "removal" stops; intact biological tissue reaches critical heating after 3.48 s, while under the influence of a high-frequency laser on the previously irradiated biological tissue development period It was also established that in order to continue laser ablation with controlled thermal effect it is necessary to remove charred areas of biological object. On the basis of the obtained data the method of laser ablation of pharyngeal tonsils was developed.

Abstract
For the purpose of decrease in intraoperative blood loss during a tonsillectomy the technique of a laser diaphanoscopy (DS) of the palatal tonsil (PT) and paratonsil space is developed. In the conditions of a transillumination of tissues of throat vessels paratonsil space which are preventively coagulated by the holmium laser are visualized. In carrying out DS of structures of a throat the 'pilot' red laser of the surgical laser LUMENIS Versa Pulse Power Suite 20W system was used. In a research there were 60 patients with chronic tonsillitis. Laser DS was carried out before tonsillectomy, at the same time 120 PT were subjected to raying. As result of the conducted research established that 60% of PT (n=72) anatomic were deeply shipped in a sidewall of a throat, 44,2% of PT (n=53) - had the expressed top pole, 0,8% of PT (n=1) - an additional segment. Also it was established that laser transillumination of paratonsil space is possible in the conditions of infiltration of fabrics isotonic physiological NaCl solution of 0,9%. Carrying out preventive coagulation of vessels of paratonsil space of Ho:YAG laser in the conditions of DS allows to reduce the volume of intraoperative blood loss to 4,17±0,37 ml that is 10,1 time less in comparison with the tonsillectomy which is carried out on traditional techniques.

Abstract
Objective To assess the long-term outcome of simultaneous treatment of a single renal cyst and ipsilateral stones with transurethral flexible ureteroscopy (FURS) lithotripsy and internal cyst drainage. Methods Patients who underwent simultaneous treatment with FURS lithotripsy and internal cyst drainage in our institution between July 2014 and September 2017 were enrolled. The cyst wall was identified endoscopically and a 1–3-cm window was created in the wall using a holmium laser. The proximal end of a double-J stent was placed in the cystic cavity to facilitate internal drainage. Results Thirteen patients underwent simultaneous treatment. No intraoperative complications with Clavien grading score >2 were noted in any patients. Mean stone burden and cyst diameter were 1.6 (range: 0.9–2.5) cm and 5.8 (range: 3.0–7.1) cm, respectively. Stone-free rates after single and complementary procedures were 84.6% and 92.3%, respectively. During the mean 33.1-month follow-up period (range: 17–54 months), seven patients (53.8%) achieved full resolution of renal cysts, five patients (38.5%) maintained >50% size reduction, and one patient (7.6%) experienced recurrence at 18 months postoperatively. Conclusions FURS with a holmium laser may constitute a safe and effective alternative procedure for simultaneous treatment of a single renal cyst and ipsilateral stones.

Abstract
INTRODUCTION The least invasive technique of PCNL is micropercutaneous nephrolithotripsy (micro-PCNL). A possibility of kidney puncture under direct endoscopic control with the creation of a working channel sized of 8-4.85 F is a characteristic feature of this system. AIM To study the possibilities of micro-PCNL and to determine its role in the treatment of kidney stones. MATERIALS AND METHODS A total of 74 patients aged 49.8+/-16.3 years were included in the study. In majority cases an isolated kidney stone was diagnosed (86.4%). The most common stone localization was pelvis (51.5%), followed by lower pole (35.9%). Considering the technical aspects of microPCNL, all patients were divided into 2 groups depending on the stone burden. In 46 patients (62.1%), the stone size was < 1.5 cm, while in 28 patients (37.9%) stones were bigger than 1.5 cm. Prestenting was performed in 54.0% due to renal colic or obstructive pyelonephritis. For the purpose of passive flushing of stone fragments during the lithotripsy, in most patients with a stone size > 1.5 cm, as well as in some prestented patients a ureteral access sheath with a diameter of 10/12 F (56.7%) was placed under x-ray control. In most patients with stones less than 1.5 cm, a 4.85 Ch sheath was utilized. In patients with larger stones, working sheath of 8 Ch was put. For stone disintegration, 50 W and 100 W holmium lasers, as well as the Russian innovative thulium fiber laser were used. RESULTS The average duration of surgery from the puncture was 30.6+/-11.6 minutes. The effectiveness was determined by use of a non-contrast computed tomography, performed one month after the surgery. An overall stone-free rate after one-session was 89.1%, and it was 93.4% and 82.4%, respectively, in patients with stones sized less and more than 1.5 cm. In 32.4% cases the stenting was placed due to the large number of small residual fragments and risk of obstruction. In one case, a conversion into a mini-PCNL was done. Two patients (2.7%) required stenting because of renal colic caused by the migration of stone fragments into the ureter. There was no bleeding. In 8.1% of cases, acute pyelonephritis was developed that was treated conservatively. In 9.4% of patients, ESWL was required due to residual stones diagnosed one month after the surgery. CONCLUSION Micro-PCNL is highly effective and safe method for treatment of kidney stones. Placing of ureteral access sheath of size 10/12 F contributes to the passive flushing of fragments during lithotripsy, which, together with the use of the 8 F working sheath, makes it possible to effectively perform micro-PCNL in patients with kidney stones larger than 1.5 cm.
