High-power holmium laser versus thulium fiber laser for endoscopic enucleation of the prostate in patients with glands larger than 80 ml: Results from the Prostate Endoscopic EnucLeation study group. Prostate Int 2024; 12:40-45. [PMID: 38523902 PMCID: PMC10960086 DOI: 10.1016/j.prnil.2023.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 12/09/2023] [Accepted: 12/11/2023] [Indexed: 03/26/2024] Open
Abstract
Background Endoscopic enucleation of the prostate (EEP) has gained acceptance as an equitable alternative to transurethral resection of the prostate for benign prostate hyperplasia (BPH). Our primary aim is to compare peri-operative outcomes of EEP using thulium fiber laser (TFL) against high-power holmium laser (HPHL) in hands of experienced surgeons for large prostates (≥80 ml in volume). Secondary outcomes were assess complications within 1 year of follow up. Materials and Methods We retrospectively reviewed patients with benign prostatic hyperplasia who underwent EEP with TFL or HPHL in 13 centers (January 2019-January 2023). Patients with prostate volume ≥80 ml were included, while those with concomitant prostate cancer, previous prostate/urethral surgery, and pelvic radiotherapy were excluded. Results Of 1,929 included patients, HPHL was utilized in 1,459 and TFL in 470. After propensity score matching (PSM) for baseline characteristics, 247 patients from each group were analyzed. Overall operative time (90 [70, 120] vs. 52.5 [39, 93] min, P < 0.001) and enucleation time (90 [70, 105] vs. 38 [25, 70] min, P < 0.001) were longer in the TFL group, with comparable morcellation time (13 [10, 19.5] vs. 13 [10, 16.5] min, P = 0.914). In terms of postoperative outcomes, there were no differences in 30-day complications such as acute urinary retention, urinary tract infection or sepsis. In the PSM cohort, univariable analyses showed that higher age, lower preoperative Qmax, higher preoperative PVRU, and longer operation time were associated with higher odds of postoperative incontinence, while 2-lobe enucleation had lower odds of incontinence compared to 3-lobe enucleation. Conclusions This real-world study reaffirms that HPHL and TFL in large prostates are equally efficacious in terms of 30-day complications. TFL with the en-bloc technique has a shorter operative time which significantly improves short- and medium-term functional outcomes.

Abstract
PURPOSE Technological advancements in laser lithotripsy are expanding into numerous fields of urology, like ureteroscopy (URS), percutaneous nephrolithotomy (PCNL), and benign and malignant soft-tissue treatments. Since the amount of research regarding lasers in urology has grown exponentially, we present a systematic review of the most recent and relevant advances encompassing all lasers used in urological endoscopic treatment. METHODS We performed a literature search using PubMed (May 2023) to obtain information about lasers for urological purposes. We included only recent data from published articles between 2021 and 2023 or articles ahead of print. RESULTS Lasers are widely used in lithotripsy for ureteric, renal, and bladder stones, benign prostate surgery, and bladder and upper tract tumor ablation. While the holmium (Ho:YAG) laser is still predominant, there seems to be more emphasis on pulse modulation and newer lasers such as thulium fiber laser (TFL) and pulsed Tm:YAG laser. CONCLUSION The use of lasers and related technological innovations have shown increasing versatility, and over time have proven to be invaluable in the management of stone lithotripsy, treatment of benign and malignant prostate diseases, and urothelial tumors. Laser endoscopic treatment is heavily based on technological nuances, and it is essential to know at least the basics of these technologies. Ultimately the choice of laser used depends on its availability, cost, surgeon experience and expertise.

Abstract
INTRODUCTION Several preclinical studies about a novel pulsed-thulium:yttrium-aluminum-garnet (p-Tm:YAG) device have been published, demonstrating its possible clinical relevance. METHODS We systematically reviewed the reality and expectations for this new p-Tm:YAG technology. A PubMed, Scopus and Embase search were performed. All relevant studies and data identified in the bibliographic search were selected, categorized, and summarized. RESULTS Tm:YAG is a solid state diode-pumped laser that emits at a wavelength of 2013 nm, in the infrared spectrum. Despite being close to the Ho:YAG emission wavelength (2120 nm), Tm:YAG is much closer to the water absorption peak and has higher absorption coefficient in liquid water. At present, there very few evaluations of the commercially available p-Tm:YAG devices. There is a lack of information on how the technical aspects, functionality and pulse mechanism can be maximized for clinical utility. Available preclinical studies suggest that p-Tm:YAG laser may potentially increase the ablated stone weight as compared to Ho:YAG under specific condition and similar laser parameters, showing lower retropulsion as well. Regarding laser safety, a preclinical study observed similar absolute temperature and cumulative equivalent minutes at 43° C as compared to Ho:YAG. Finally, laser-associated soft-tissue damage was assessed at histological level, showing similar extent of alterations due to coagulation and necrosis when compared with the other clinically relevant lasers. CONCLUSIONS The p-Tm:YAG appears to be a potential alternative to the Ho:YAG and TFL according to these preliminary laboratory data. Due to its novelty, further studies are needed to broaden our understanding of its functioning and clinical applicability.

Thulium: YAG vs continuous-wave thulium fiber laser enucleation of the prostate: do potential advantages of thulium fiber lasers translate into relevant clinical differences? World J Urol 2023; 41:143-150. [PMID: 36357602 DOI: 10.1007/s00345-022-04201-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Accepted: 10/25/2022] [Indexed: 11/12/2022] Open
Abstract
PURPOSE To compare endoscopic enucleation of the prostate using a thulium: yttrium-aluminum-garnet (Tm:YAG) laser and a super-pulsed thulium fiber laser set in continuous-wave (CW) mode, and to evaluate whether theoretical advantages of thulium fiber lasers, related to their shorter wavelength, translate into relevant clinical differences. METHODS In total, 110 patients suffering from lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia were randomized to undergo either thulium:YAG laser enucleation of the prostate (ThuLEP) or CW thulium fiber laser enucleation of the prostate (CW-ThuFLEP). Intraoperative and postoperative variables and complications were compared. Micturition improvement was assessed at 3-month follow-up using the International Prostate Symptom Score (IPSS), post-void residual urine (PVR) and maximum flow rate (Qmax). Erectile function was evaluated using the International Index of Erectile Function-5 (IIEF-5). RESULTS No significant differences between the ThuLEP and CW-ThuFLEP groups were found in terms of operative time (70.69 vs 72.41 min), enucleation time (50.23 vs 53.33 min), enucleated tissue weight (40.2 vs 41.9 g), enucleation efficiency (0.80 vs 0.79 g/min), catheterization time (2.45 vs 2.57 days), hospital stay (2.82 vs 2.95 days) and hemoglobin drop (1.05 vs 1.27 g/dl). At 3-month follow-up, no significant differences were found in IPSS (5.09 vs 5.81), Qmax (26.51 vs 27.13 ml/s), PVR (25.22 vs 23.81 ml) and IIEF-5 (14.01 vs 14.54). CONCLUSION ThuLEP and CW-ThuFLEP were equivalent in relieving patients from LUTS and improving micturition. Theoretical advantages of the TFL, such as shallower penetration depth and improved vaporization capacity, did not translate into relevant perioperative outcomes or clinical differences.

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 The aim of the study was to systematically review the literature and describe perioperative complications of holmium laser enucleation of the prostate (HoLEP), including the Clavien-Dindo classification of surgical complications. METHODS All English language publications on HoLEP were evaluated. We followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) guidelines to evaluate PubMed®, Scopus®, and Web of Science™ databases from January 1, 1998, to June 1, 2020. RESULTS Fifty-seven studies were included, for a total of 10,371 procedures. We distinguished between intra-, peri-, and postoperative complications. Overall, the rate of complications is 0-7%. Intraoperative complications include incomplete morcellation (2.3%), capsular perforation (2.2%), bladder (2.4%), and ureteric orifice (0.4%) injuries. Perioperative complications include postoperative urinary retention (0.2%), hematuria and clot retention (2.6%), and cystoscopy for clot evacuation (0.7%). Postoperative complications include dysuria (7.5%), stress (4.0%), urge (1.8%), transient (7%) and permanent (1.3%) urinary incontinence, urethral stricture (2%) and bladder neck contracture (1%). CONCLUSIONS HoLEP is a safe procedure, with a satisfactory low complication rate. The most common reported perioperative complications are not severe (Clavien-Dindo classification grades 1-2). Further randomized studies are certainly warranted to fully determine the predictor of surgical complications in order to prevent them and improve this technique.

Novel ultrasound-based volume estimation of prostatic benign enlargement to improve decision-making on surgical approach. Ther Adv Urol 2021; 13:1756287221993301. [PMID: 33633800 PMCID: PMC7887671 DOI: 10.1177/1756287221993301] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Accepted: 01/13/2020] [Indexed: 11/18/2022] Open
Abstract
Aim: To assess the precision of preoperative ultrasonography (US)-determined prostate volume and to propose formulas for improving it. Methods: This retrospective study comprised 155 consecutive men who underwent open prostatectomy for benign prostatic hyperplasia (BPH) between 2013 and 2019. Preoperative prostate volume was estimated by either abdominal US (AUS) (n = 92) or transrectal US (TRUS) (n = 63), and was compared with the weight of surgically enucleated tissue at a conversion rate of 1 ml (US) = 1 g tissue. Statistical analysis was conducted and a novel formula for prostate volume was constructed. Results: The median prostate volumes by AUS and TRUS were 140 ml [interquartile ratio (IQR) 111–182] and 108 ml (IQR 93–120), respectively. Enucleated tissue weight was lower than the AUS assessment by a median difference of 50 g (IQR 28.7–75.7; p < 0.001), and lower than the TRUS assessment by a median difference of 27 g, IQR 10–43, p < 0.001). Using a cutoff of 80 ml, 30 (33%) AUS patients and 23 (36%) TRUS patients underwent unneeded open procedures. Mathematical calculations revealed two formulas that significantly adjusted for the actual weight: 1.082*Age + 0.523*AUS − 53.845 for AUS and 0.138*age + 2.22*prostate-specific antigen + 0.453*TRUS + 11.682 for TRUS (p < 0.001). These formulas increased the overall US prostate volume accuracy from 65% to 85%. Conclusion: Assessment of prostate volume by US is imprecise for decision-making of whether to perform open simple prostatectomy for BPH. Our novel formulas may enhance stratification of patients with prostatic enlargement to a more optimal surgical approach. Future studies in larger cohorts are needed to substantiate our results.

Maruccia S, Fulgheri I, Montanari E, Casellato S, Boeri L. Nomenclature in thulium laser treatment of benign prostatic hyperplasia: it's time to pull the rabbit out of the hat. Lasers Med Sci 2021; 36:1355-1367. [PMID: 33389305 DOI: 10.1007/s10103-020-03227-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Accepted: 12/16/2020] [Indexed: 12/14/2022]
Abstract
We performed a narrative review with the focus on laser settings and surgical procedure with thulium laser. Our primary goal was to define the most valid settings of each surgical procedure to overcome the inconsistency about nomenclature of thulium surgery and to ensure comparability of future publications. A literature search of articles on thulium laser treatment of benign prostatic hyperplasia (BPH) was conducted between 2009 and 2019. We proposed a new classification standard for laser settings and associated surgical procedure. Each article was analyzed and categorized as concordant or discordant referring to the new classification. In total, 74 papers were included in this narrative review. Overall, 43% and 42% of included studies reported discordant laser parameters and surgical description, respectively. Most of the studies on vaporization were categorized as discordant because they reported a medium/low laser setting instead of high power. Conversely, 93.3% of studies on enucleation were deemed as discordant for laser setting because they reported high power parameters instead of medium-low power setting. Most of the studies on laser enucleation and vapo/enucleation were considered discordant for surgical procedure since authors did not mention the use of mechanical vs. laser method for enucleation. The current literature lacks a uniform definition and standardization of the terminology of thulium laser settings and surgical techniques to guarantee comparability between different approaches. We found a huge heterogeneity in 10 years of surgery with thulium laser. We proposed a new classification of laser setting and procedural description for categorization of thulium laser surgery for BPH.

Abstract
Objective To assess the value of clinically relevant data for predicting the failure of removal of the urinary catheter within 48 hours after TUERP. Materials and Methods. We retrospectively analyzed the medical records of 357 patients who underwent TUERP between January 2015 and July 2018, all of whom stopped bladder irrigation and removed urinary catheter within 48 hours after the operation. According to whether the removal of the catheter was successful, the patients were classified into 2 groups: Group A was successful and group B was a failure. Univariate analysis was performed to determine the association between the failure of removal of the catheter and the patients' preoperative clinical characteristics. Logistic regression analysis and receiver operating characteristic analysis (ROC) were conducted to establish the prediction model. Then the area under the curve (AUC) and the cut-off value were calculated. Results 357 patients were divided into group A (n = 305, 85.4%) and group B (n = 305, 85.4%) and group B (P=0.006), history of acute urinary retention (AUR) (P=0.006), history of acute urinary retention (AUR) (P=0.006), history of acute urinary retention (AUR) (P=0.006), history of acute urinary retention (AUR) (P=0.006), history of acute urinary retention (AUR) (P=0.006), history of acute urinary retention (AUR) (P=0.006), history of acute urinary retention (AUR) (P=0.006), history of acute urinary retention (AUR) (P=0.006), history of acute urinary retention (AUR) ( Conclusion This study demonstrated that IPSS, QoL, drug medication, history of AUR, TPV, and IPP are independent factors associated with the failure of removal of the urethral catheter within 48 hours after TUERP.

Abstract
The spectrum of surgical procedures for the minimally invasive treatment of benign prostatic hyperplasia (BPH) has significantly increased over the last two decades. The simple suprapubic prostatectomy (subtotal prostatectomy, SP) has largely lost relevance in current practice. On the other hand, transurethral resection of the prostate (TURP) has been further standardized and potentially made safer by the introduction of the bipolar technique and low-pressure systems.Transurethral (endoscopic) enucleation techniques (endoscopic enucleation of the prostate, EEP) are increasingly competing with the current gold standard TURP and are replacing SP for treatment of larger adenomas. This approach is especially related to the rapid development of laser technology, which has sustainably changed the face of modern BPH treatment in a similar way to stone therapy. This has been incorporated in the clinical patient management, clinical studies and standardization of numerous surgical techniques that are systematically described in this article. Additionally, efforts have also been made to use other energy sources, such as bipolar current in EEP. With respect to scientific objectivity, high-quality clinical trials are regularly published which further strengthen the position of EEP.

Abstract
Benign prostatic hyperplasia (BPH) is one of the most common conditions affecting men. BPH can lead to a number of symptoms for patients commonly referred to as lower urinary tract symptoms (LUTS). Over the last decade, increased modifiable risk factors, such as metabolic disease and obesity, have resulted in an increased incidence of BPH. This increasing incidence has brought about a multitude of treatment modalities in the last two decades. With so many treatment modalities available, physicians are tasked with selecting the optimal therapy for their patients. Current therapies can first be divided into medical or surgical intervention. Medical therapy for BPH includes 5-alpha-reductase inhibitors and alpha-blockers, or a combination of both. Surgical interventions include a conventional transurethral resection of the prostate (TURP), as well as newer modalities such as bipolar TURP, holmium laser enucleation of the prostate (HoLEP), Greenlight and thulium laser, and prostatic urethral lift (PUL). Emerging therapies in this field must also be further investigated for safety and efficacy. This narrative review attempts to consolidate current and emerging treatment options for BPH and highlights the need for additional investigation on optimizing treatment selection.

Abstract
PURPOSE To compare the perioperative and functional outcomes of holmium laser enucleation of the prostate (HoLEP) and thulium laser enucleation of the prostate (ThuLEP) for the treatment of large-volume benign prostatic hyperplasia (BPH) (> 80 ml). METHODS A total of 116 consecutive patients with BPH were randomized to be treated surgically with either HoLEP (n = 58) or ThuLEP (n = 58), following the classical three-lobe enucleation technique. Follow-up was assessed at 1, 3, 6, 12 and 18 months after surgery. RESULTS At 18 months, the lower urinary tract symptom index was improved significantly in both groups compared with the baseline values. The operative time (78.4 ± 8.0 vs. 71.4 ± 6.4 min) and enucleation time (61.2 ± 5.4 vs. 56.4 ± 8.4 min) were significantly shorter for ThuLEP compared to HoLEP (both p < 0.001). There were no significant differences between the two groups regarding morcellation time, resected weight, hemoglobin decrease, catheter time and hospital stay (p > 0.05). The HoLEP and ThuLEP groups had equivalent International Prostate Symptom Scores (3 [3-3] vs. 3 [3-3], p = 0.776), quality of life (1 [1-2] vs. 2 [1-2], p = 0.809), Qmax (25.3 ± 4.8 ml/s vs. 24.7 ± 4.4 ml/s, p = 0.470), postvoid residual urine (PVR) (6.1 [2.6-20.8] vs. 7.7 [3.1-22.8] ml, p = 0.449) and PSA (0.84 ± 0.32 vs. 0.90 ± 0.34 ml, p = 0.309) at 18 months postoperatively. CONCLUSION Both HoLEP and ThuLEP relieve lower urinary tract symptoms in a comparable way with high efficacy and safety. ThuLEP was statistically superior to HoLEP in operation time and enucleation time, although the differences were clinically negligible.

Abstract
Objective: To compare the clinical efficacy and safety between diode laser (980 nm) enucleation of the prostate (DiLEP) and holmium laser enucleation of the prostate (HoLEP) for treating benign prostatic hyperplasia (BPH). Patients and Methods: One hundred twenty-six BPH patients in our hospital from December 2016 to December 2017 were enrolled in this study. They were randomized to the DiLEP group or HoLEP group, which were administrated with DiLEP and HoLEP treatment, respectively. The patient's characteristics, such as age, body mass index, comorbidities, prostate volume, and prostate-specific antigen, were recorded before surgery. The perioperative outcomes and complications were also compared. The maximum flow rate (Qmax), postvoid residual (PVR), international prostate symptom score (IPSS), and quality-of-life (QoL) score were assessed at baseline and 3, 6, and 12 months postoperatively. Results: No significant differences were observed for the patient's baseline characteristics between both groups. For the perioperative outcomes, including operative time, resected tissue weight, catheter duration, and hospital stay, no significant difference was found between the two groups. However, the DiLEP group showed less blood loss and decrease in hemoglobin compared with the HoLEP group. The incidence of early or late complications was similar for both groups. The Qmax, PVR, IPSS, and QoL for both groups of patients were dramatically improved after surgery. By comparing the Qmax, PVR, IPSS, and QoL between the two groups, no significant differences were detected in the 3-, 6-, or 12-month follow-up. Conclusions: This study demonstrated that both DiLEP and HoLEP are efficient and safe treatments for BPH patients. DiLEP showed less blood loss and decrease in hemoglobin than HoLEP, which indicated that the diode laser (980 nm) generates a better hemostasis effect.

Abstract
PURPOSE To perform a cumulative analysis of the current evidence on the surgical and functional outcomes of bipolar endoscopic enucleation of the prostate (b-EEP) versus bipolar transurethral resection of the prostate (b-TURP). METHODS A systematic review of the literature was performed on PubMed, Ovid®, and Scopus® according to Preferred Reporting Items for Systematic Review and Meta-analysis Statement (PRISMA Statement). The meta-analysis was conducted using the Review Manager 5.3 software. Parameters of interest were surgical and functional outcomes. Weighted mean difference, and odds ratio with 95% confidence interval were calculated for continuous and binary variables, respectively. Pooled estimates were calculated using the random-effect model. RESULTS Fourteen comparative studies were included. No statistically significant difference in terms of overall baseline characteristics was found. b-EEP had higher amount of resected tissue (p < 0.0001), shorter catheter time (p = 0.006), lower Hb drop (p = 0.03), and shorter length of stay (p < 0.0001). Equally, overall post-operative complications were lower (p = 0.01) as well as short (p = 0.04), and long-term complication rate (p = 0.04). There was higher re-intervention rate in the b-TURP group (p = 0.02) whereas b-EEP group had smaller residual prostate volume (p = 0.03), and lower post-operative PSA values (p < 0.00001). At long term, b-EEP presented lower IPSS (p = 0.04), higher Qmax (p = 0.002), and lower PVR (p < 0.00001). CONCLUSIONS b-EEP is an effective and safe surgical treatment for BPO. This procedure might offer several advantages over standard b-TURP, including the resection of a larger amount of tissue within the same operative time, shorter hospitalization, lower risk of complications, and lower re-intervention rate. This was submitted to PROSPERO registry: CRD42019126748.

The effect of prostatic tissue density on the perioperative outcomes of Holmium laser enucleation of prostate (HoLEP): a pilot study. World J Urol 2019; 38:455-461. [PMID: 31076849 DOI: 10.1007/s00345-019-02802-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2018] [Accepted: 05/04/2019] [Indexed: 12/27/2022] Open
Abstract
PURPOSE To evaluate the effect of prostate tissue density (PTD) on perioperative Holmium laser enucleation of prostate (HoLEP) outcomes. METHODS Two hundred fourteen patients underwent HoLEP between December 2016 and August 2018 (group 1: PTD < 1 g/mL and group 2: PTD ≥ 1 g/mL). Enucleation time (ET), morcellation time (MT), total operation time (TOT), total laser energy (TLE), efficiency of laser (EL), efficiency of enucleation (EE), efficiency of morcellation (EM), enucleation rate (ER), and enucleated tissue weight (ETW) were recorded. RESULTS The mean ages of the groups 1, 2 were 61.36±5.92 and 63.1±7.52 years, respectively. TOT (76.4 vs 86.21 min), ET (69.18 vs 79.94 min), EE (0.80 vs 0.91 g/min), and ETW (55.8 vs 70.23 g) were not significantly different between the two groups. However, the MT was longer in group 2 (11.27 ± 8.57 min and 7.22 ± 5.46 min, p = 0.0001). Furthermore, EM was higher in group 1 (9.81 ± 5.61 g/min and 7.45 ± 4.14 g/min, p = 0.0003). The EL and TLE were similar in both groups. PTD positively correlated with MT (ρ = 0.272, p = 0.0005) and negatively correlated with EM (ρ = - 0.315, p = 0.0001). No correlations were identified between the PTD and EL or EE. CONCLUSIONS PTD is a factor that influences the HoLEP on perioperative outcomes. The PTD particularly affects the morcellation phase of the surgery. Patients with higher PTD will have a longer duration of MT and lesser EM. Future studies with the use of different imaging methods will give insight into the duration and difficulty of the HoLEP.

[PMID: 31015537 PMCID: PMC6478674 DOI: 10.1038/s41598-019-42903-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2018] [Accepted: 04/10/2019] [Indexed: 11/24/2022] Open
Abstract
We aimed to compare the efficacy and safety of Multipulse laser vaporesection of the prostate (MPVP) versus plasmakinetic resection of the prostate (PKRP) for treatment of patients with benign prostate obstruction (BPO) in a prospective trial. From January 2016 to April 2017, a total of 144 patients were included in the cohort study, of whom 73 patients underwent MPVP and 71 underwent PKRP. All patients received pre-operative evaluation and followed up at 1, 3, 6 and 12 months postoperatively. Baseline characteristics, perioperative data and postoperative outcomes were compared. Early (within 30 days postoperatively) and late complications were also recorded. Preoperative data, including age, prostate volume, international prostate symptom score (IPSS), International Index of Erectile Function Questionnaires (IIEF-5), the rate of anticoagulants use, Charlson comorbidity index were similar in two groups. Peri-operative parameters, including the rate of transfusion, and decrease in hemoglobin level were comparable. The operative time, the duration of catheterization and length of hospital stay were significantly shorter in the MPVP group. The voiding parameters and the quality-of-life scores (QoL) improved significantly in both groups postoperatively. There was a significantly difference in QoL at 1-year in the MPVP group (p < 0.001), under mixed model analysis with random effect and Bonferroni correction. There were no significant differences in improvement of IPSS, Qmax, IIEF-5, residual prostate volume ratio and PSA level reduction at the 1-year follow-up. MPVP was significantly superior to PKRP in terms of a reduction in overall complication rate (21.9% vs 45.0%, p = 0.004). Both treatments led to comparable symptomatic improvements. MPVP demonstrates satisfactory efficiency, shorter catheterization time and shorter hospital stay. Our data revealed that MPVP may be a promising technique which is safe and favorable alternative for patients with BPO.

Abstract
Objective To provide the first large single-operator case series of patients who undergo “en bloc” thulium laser enucleation of the prostate (ThuLEP) and to demonstrate an improvement in enucleation efficacy with experience. Methods We prospectively evaluated a cohort of patients with symptomatic benign prostatic hyperplasia (BPH) who underwent “en bloc” ThuLEP between May 2015 and November 2017. Association between dependent variables (delivered energy and operating time) and independent variables (adenoma volume and experience) were estimated with regression analysis. The experience was calculated as the time interval between the date of the first operation of the series and the date of the operation being considered. Results A total of 100 patients were registered for the study. Median operative time was 56.5 min (interquartile range [IQR]: 40–85 min). Median enucleation time was 17.4 min (IQR: 15–21.5 min). Median enucleation index (enucleation time per adenoma gram) was 0.3 min/g (0.2–0.3 min/g). The overall operative time is not influenced by experience, but we registered a significant trend towards a reduction in the total amount of energy delivered energy normalized per adenoma gram (p = 0.0148). Conclusion We believe that further attention is needed for these new “en bloc” prostatic enucleation techniques, which can facilitate some surgical steps, leading to a widespread use of laser technology for BPH surgical treatment.

Abstract
Since prehistoric times, our understanding of urology has rapidly expanded. Whilst primitive urologists began by using urine as a therapeutic substance, modern urologists may find themselves removing a kidney remotely by driving a robotic arm, with seven degrees of movement, while using image overlay-augmented reality. This review provides an insight into the potential status of urological technology in 20 years' time, assessed through an analysis of developments in imaging, diagnostics, robotics and further technologies. A particular emphasis is given to the promising fields of minimally invasive techniques, nanotechnology and tissue engineering, which likely hold the key to a new era for urology.

A Randomized Trial Comparing The Learning Curve of 3 Endoscopic Enucleation Techniques (HoLEP, ThuFLEP, and MEP) for BPH Using Mentoring Approach-Initial Results. Urology 2018; 121:51-57. [PMID: 30053397 DOI: 10.1016/j.urology.2018.06.045] [Citation(s) in RCA: 48] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2018] [Revised: 05/30/2018] [Accepted: 06/07/2018] [Indexed: 10/28/2022]
Abstract
OBJECTIVE To assess the differences in the learning curve associated with different techniques of endoscopic enucleation of the prostate. MATERIALS AND METHODS Ninety patients were randomly assigned into 3 groups (30 patients in each): HoLEP, ThuFLEP or MEP. Inclusion criteria for the study included prostate volume <80 cc, IPSS > 20, or Qmax < 10. The EEPs were performed by 3 surgeons experienced in transurethral resection of the prostate. Assignment of surgeons to surgical technique was also randomized. None of the surgeons had prior experience in EEP. RESULTS ThuFLEP was slightly superior (with no significant difference [P > .05]) to HoLEP and MEP in terms of overall enucleation rate-1.0 g/min vs 0.8 g/min and 0.7 g/min, respectively. We observed similar enucleation rates at the initial stages of training (first 20 surgeries) with insignificant increase in ThuFLEP efficiency. At next 10 surgeries ThuFLEP and HoLEP efficiency were higher than of MEP (P < .001) without significant difference between techniques of laser EEP (P = .07). CONCLUSION Endoscopic enucleation of the prostate can be adopted safely and effectively within 30 surgeries if the technique is learned with a mentoring approach. EEP is shown to be safe and effective even in the initial stages of learning. Laser EEP (HoLEP, ThuFLEP) appears to lend itself to quicker adaptation compared MEP.

Abstract
Background The aim of our study was to compare perioperative and functional outcomes of two different prostatic laser enucleation techniques performed in two high-volume centers: 100 W holmium laser enucleation of the prostate (HoLEP) (Lyon, France) and 110 W thulium laser enucleation of the prostate (ThuLEP) (Varese, Italy). Materials and Methods A nonrandomized, observational, retrospective and matched-pair analysis was performed on two homogeneous groups of 117 patients that underwent prostate laser enucleation in the HoLEP or ThuLEP centers between January 2015 and April 2017, following the classical 'three lobes' enucleation technique. The American Society of Anesthesiologists (ASA) score and prostate volume were the main parameters considered for matching the patients between the two groups. Patients on anticoagulant therapy, with documented detrusor hypoactivity or hyperactivity or with the finding of concurrent prostate cancer were excluded from the study. Follow up was assessed at 3, 6 and 12 months after surgery. Results Median enucleation and morcellation time was 75.5 and 11.5 min, respectively, in the HoLEP group versus 70.5 and 12 min, respectively, in the ThuLEP group (p = 0.001 and 0.49, respectively). Enucleated adenoma weight was comparable (44 g versus 45.6 g, p = 0.60). Energy index (3884.63 versus 4137.35 J/g, p = 0.30) and enucleation index (0.57 versus 0.6 g/min, p = 0.81) were similar in the two groups. Catheterization time was comparable (1 versus 1 day; p = 0.14). The International Prostate Symptom Score and Quality of Life score significantly decreased, as well as maximal urinary flow rate. Median prostate-specific antigen (PSA) drop 1 year after surgery was 2.1 ng/ml in the HoLEP group (-52.83%) versus 1.75 ng/ml in the ThuLEP group (-47.85%) (p = 0.013). Conclusion Both HoLEP (100 W) and ThuLEP (110 W) relieve lower urinary tract symptoms in a comparable way with high efficacy and safety, with negligible clinical differences.

Abstract
Esophageal achalasia is a type of motility disorder characterized by incomplete relaxation of lower esophageal sphincter (LES) and absence of esophageal peristalsis. Peroral endoscopic myotomy (POEM) is a new treatment option for achalasia that is less invasive, more effective, and safe as compared to surgery. High-frequency electrotome is commonly used in POEM, but takes longer time to make the tunnel in the esophagus and causes many complications. The thulium laser decreases the risk of bleeding and perforation in endoscopy but has not been reported in digestive diseases, especially in POEM. Therefore, the aim of this study is to evaluate the feasibility of the 1940 nm thulium laser in POEM. From March 2015 to August 2015, five patients with achalasia at the Digestive department, Beijing Friendship Hospital, Capital Medical University, Beijing, China were included. Before the procedure, the patients' gender, age, and duration of symptoms were recorded. Eckardt symptom score and LES thickness, which measured by endoscopic ultrasonography, were recorded. While the subtypes of achalasia (according to the Chicago classification), lower esophagus sphincter resting pressure (LESRP) and integrated relaxation pressure (IRP) were measured by HRM for all patients. Barium esophagram was also used to rule out anatomical lesions, esophageal varices, or neoplasia, which may cause similar symptoms. All examinations were performed one week before POEM. POEM was performed with the 1940 nm thulium laser under general anesthesia. Eckardt score, procedure duration, myotomy length, and complications were recorded one week after POEM. All the patients were followed-up at two weeks and four weeks after POEM. POEM was successfully performed in all five patients. The mean age of the patients was 38.8 years (24-54 years). Achalasia subtypes were type I (n = 1), II (n = 2), and III (n = 2). The operation duration was 186, 180, 111, 75, and 126 minutes for the five cases. Pre/postprocedure Eckardt scores were 3/0, 7/0, 5/1, 6/0, and 9/0. Pre/postprocedure LESRP (mmHg) were 45.3/26.4, 18.0/1.1, 25.8/10.4, 16.5/11.2, and 24.2/20.8. Pre/postprocedure IRP (mmHg) were 27.3/15.5, 15.4/4.2, 5.7/6.8, 15.5/10.1, and 13.1/14, respectively. No adverse events occurred during the procedure. After POEM, subcutaneous emphysema occurred in case 1 on the first day, which relieved spontaneously after two days without special intervention. Infection occurred in case 5 on the day of POEM was healed with antibiotics three days later. The 1940 nm thulium laser is feasible for POEM procedure. Further studies are needed to determine whether the 1940 nm thulium laser is better than high-frequency electrotome.
