Efficacy of Hexaminolevulinate Photodynamic Diagnosis of Non-Muscle Invasive Bladder Cancer
摘要： Objective: This study evaluated the efficacy of hexaminolevulinate fluorescence cystoscopy as a diagnostic tool for bladder cancer. The study was a case series in the Department of Urology in Hippokratio General Hospital of Athens between October 2008 and May 2012. Methods: Fifty patients (43 males and 7 females) who were investigated for hematuria were included in the study. White light cystoscopy (WLC) was first performed in all patients and after was performed a fluorescence cystoscopy (BLC-blue light cystoscopy). Biopsies were collected from any suspicious area and resection of the tumors identified (TUR).Whenever no suspicious areas could be seen, a standard random mapping including 8 biopsies overall was completed. Results: Patients demographic data and clinical history are presented in Table 1. Two-hundred twenty specimens were extracted and bladder cancer was diagnosed in 137. There were 17 CIS lesions all diagnosed with BLC whereas only 11 with WLC. WLC correctly diagnosed 109/140 specimens and the positive and negative predictive values were 77.9% and 65% respectively. The sensitivity and specificity were 79.6% and 62.6% respectively. BLC diagnosed 125/169 specimens and the positive and negative predictive values were 73.9% and 76.5% respectively. The sensitivity of BLC was 91.2% and the specificity 46.9%. Conclusion: Hexaminolevulinate-guided cystoscopy is a valuable diagnostic method, with considerably improved accuracy and improvement in diagnosis of non-muscle-invasive bladder cancer and especially CIS.

Holmium laser enucleation of the prostate for very large benign prostatic hyperplasia (a?￥a??200??cc)
摘要： Purpose Patients presenting with prostate gland sizes greater than 200?cc pose a unique surgical challenge to both patients and surgeons. The objective of this study is to critically assess the efficacy and risks associated with performing holmium laser enucleation of the prostate (HoLEP) on glands ≥ 200?cc. Materials and methods Using a prospective maintained database, all consecutive benign prostatic hyperplasia (BPH) patients with gland size ≥ 200?cc who underwent HoLEP were included. We reported patient preoperative, intraoperative, postoperative outcomes and complications. Subgroup analysis of outcomes was stratified by gland sizes 200–299?cc and ≥ 300?cc. Univariate analysis using Kruskal–Wallis and Fisher exact test was performed to compare the two groups. Results There were 88 patients with a mean preoperative gland size of 255.9?cc (200–770?cc). Mean operative (171 vs 182?min) and enucleation time (77 vs 83?min) were not different between the two subgroups (200–299?cc vs ≥ 300?cc). Enucleation efficiency was greater for glands ≥ 300?cc (2.6?cc/min vs 2.0?cc/min, p = 0.04). Morcellation time was longer in the ≥ 300?cc group (74.5?min vs 46.8?min, p = 0.021). Mean length of stay was 1.8 ± 1.2?days and catheter duration was 2.6 ± 2.7?days. 1 (1.1%) patient required retreatment of BPH at last follow-up. The main limitation of this study is the retrospective data analysis. Conclusions Holmium laser enucleation for prostate glands volume > 200?cc is feasible with minimal morbidity. These data further reinforce the size independence success of this procedure for BPH.

The effect of holmium laser resection versus standard transurethral resection on non-muscle-invasive bladder cancer: a systematic review and meta-analysis
摘要： To explore the advantages and limitations of holmium laser resection of the bladder tumor (HOLRBT) versus standard transurethral resection of the bladder tumor (TURBT) in the treatment of non-muscle-invasive bladder cancer (NMIBC), the eligible studies were selected from the following databases: PubMed, Cochrane Library, and Embase. Studies comparing HOLRBT and TURBT for patients with NMIBC were included. The outcomes of interest were time of operation, catheterization and hospitalization, rates of recurrence, and perioperative complications, including obturator nerve reflex, bladder perforation, bladder irritation, and urethral stricture. Results of all data were compared and analyzed by Review Manager 5.3. A total of 9 comparative studies were finally included for this analysis. Pooled data demonstrated that HOLRBT significantly reduced the time to catheterization and hospitalization, the rate of recurrence in 2 years of follow-up, obturator nerve reflex, bladder perforation, and bladder irritation, compared with those in TURBT, respectively. However, no significant difference found between HOLRBT and TURBT in the time of operation, rate of recurrence in 1-year follow-up, and urethral stricture. The results of this research reached that HOLRBT would be a better choice than TURBT for patients with NMIBC.

Comparison of photoselective green light laser vaporisation versus traditional transurethral resection for benign prostate hyperplasia: an updated systematic review and meta-analysis of randomised controlled trials and prospective studies
摘要： Objective To assess the efficacy and safety of green-light laser photoselective vaporisation of the prostate (PVP) compared with transurethral resection of the prostate (TURP) for lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). Design Systematic review and meta-analysis, conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. Data sources PubMed, EMBASE, the Cochrane Library until October 2018. Eligibility criteria Randomised controlled trials and prospective studies comparing the safety and efficacy of PVP versus TURP for LUTS manifesting through BPH. Data extraction and synthesis Perioperative parameters, complications rates and functional outcomes including treatment-related adverse events such as International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), postvoid residual (PVR), quality of life (QoL) and International Index of Erectile Function (IIEF). results 22 publications consisting of 2665 patients were analysed. Pooled analysis revealed PVP is associated with reduced blood loss, transfusion, clot retention, TUR syndrome, capsular perforation, catheterisation time and hospitalisation, but also with a higher reintervention rate and longer intervention duration (all p<0.05). No significant difference in IPSS, Qmax, QoL, PVR or IIEF at 3, 24, 36 or 60 months was identified. There was a significant difference in QoL at 6 months (MD=?0.08; 95% CI ?0.13 to ?0.02; p=0.007), and IPSS (MD = ?0.10; 95% CI ?0.15 to ?0.05; p<0.0001) and Qmax (MD=0.62; 95% CI 0.06 to 1.19; p=0.03) at 12 months, although these differences were not clinically relevant. Conclusion PVP is an effective alternative, holding additional safety benefits. PVP has equivalent long-term IPSS, Qmax, QoL, PVR, IIEF efficacy and fewer complications. The main drawbacks are dysuria and reintervention, although both can be managed with non-invasive techniques. The additional shortcoming is that PVP does not acquire histological tissue examination which removes an opportunity to identify prostate cancer.

Laser enucleation of the prostate versus transurethral resection of the prostate: perioperative outcomes from the ACS NSQIP database
摘要： Purpose To compare the perioperative outcomes associated with laser enucleation of the prostate (LEP) and transurethral resection of the prostate (TURP) using a national database. Methods The American College of Surgeons National Surgical Quality Improvement Program database was reviewed for patients who underwent TURP or LEP from 2008 to 2016. Baseline demographics, comorbidities, and predisposition to bleeding were compared between TURP and LEP. The 30-day perioperative outcomes including operative time, length of hospital stay (LOS), return to the operating room (OR), bleeding requiring transfusion, and organ system-specific complications were compared between the procedures. A multivariate logistic regression analysis was performed, adjusting for the type of surgery and other covariates. Results The series included 37,577 TURP and 2869 LEP procedures. While TURP was associated with a shorter operative time (55.20 ± 37.80 min) than LEP (102.80 ± 62.30 min), the latter was associated with a shorter hospital stay (1.29 ± 2.73 days) than TURP (2.05 ± 5.20 days). Compared to TURP, LEP had 0.52 (0.47–0.58) times the odds of a LOS > 1 day and 0.67 (0.54–0.83) times the odds of developing urinary tract infections. Nevertheless, no difference was found for other postoperative complications, need for transfusion, and return to OR. Conclusion Real-life data from a large national database confirmed that LEP is a safe and reproducible procedure to treat benign prostatic obstruction. Compared to TURP, LEP was associated with a lower rate of infectious complications and a shorter LOS at the expense of an increased operative time.

Current surgical techniques of enucleation in holmium laser enucleation of the prostate
摘要： Holmium laser enucleation of the prostate (HoLEP) has been accepted as the most efficient method of transurethral surgery for benign prostatic hyperplasia. The originally developed three-lobe technique has popularized this surgery; this method is based on three longitudinal incisions, by which the median lobe is removed, and subsequently, both lateral lobes are enucleated. To maintain a consistent surgical plane and to minimize sphincteric damage, the traditional three-lobe technique is continuously being refined and evolving. A few modifications of the original technique have been developed, and several en bloc enucleation methods have been introduced. However, more clinical evidence is required to show the superiority of newer techniques over the original three-lobe technique in terms of efficacy and long-term side effects. To date, none of the newer techniques have been accepted as a standard technique for HoLEP.

Mind the Gaps: Adoption and Underutilization of Holmium Laser Enucleation of the Prostate (HoLEP) in the United States from 2008-2014
摘要： There is increasing recognition of the advantages of Holmium Laser Enucleation of the Prostate (HoLEP) for Benign Prostatic Hypertrophy (BPH) treatment In the United States (U.S.) but relatively little is known about the extent of HoLEP adoption over time. This study aims to assess national HoLEP adoption rates and regional trends from 2008‐2014. Methods: We retrospectively analyzed a dataset of 100% Medicare claims to determine the rate of U.S. HoLEP adoption in 2008, 2011 and 2014. Rates were adjusted by age and race and stratified by Hospital Referral Region (HRR). Linear and logistic regression models were used to assess for trends in HoLEP adoption over time. Results: Total U.S. BPH cases decreased 24% from 2008‐2014 and HoLEP cases increased significantly from 1086 (2008) to 3368 (2014). Despite this, HoLEP accounted for just 4% of total BPH cases in 2014. In 2008 28/306 (9%) of HRRs recorded >10 HoLEPs/year. This increased to 89 HRRs (29%) in 2011 but stabilized at 94 HRRs (31%) in 2014. In 2014, over 50% of states still had only 0‐1 sites doing 10+ HoLEPs/year. Conclusions: Based on this 100% sample of Medicare claims from 2008‐2014, surgical BPH treatment volume has decreased while HoLEP volume and regional adoption have tripled. However, rates of HoLEP remain extremely low at just 4% of all BPH procedures in 2014 and large regional gaps in care exist. This data indicates that HoLEP remains substantially under‐ utilized and the majority of regions still lack access to centers performing >10 HoLEPs/year.

Novel thulium fiber laser for endoscopic enucleation of the prostate: A prospective comparison with conventional transurethral resection of the prostate
摘要： Objective: To compare the efficacy and safety of a novel thulium fiber laser for endoscopic enucleation of the prostate with monopolar transurethral resection of the prostate in patients with smaller glands (<80 cc). Methods: A total of 51 patients underwent thulium fiber laser enucleation of the prostate, and 52 patients underwent monopolar transurethral resection of the prostate. All patients were assessed preoperatively, and at 3, 6, and 12 months postoperatively (International Prostate Symptom Score, maximum urine flow rate, International Prostate Symptom Score-quality of life). Preoperative prostate volumes and prostate-specific antigen levels were complications were graded according to the Clavien classification. Results: Mean surgery time was longer in the thulium fiber laser enucleation of the prostate group (46.6 ± 10.2 vs 39.9 ± 8.6 min, P < 0.001), while catheterization and hospital stay were greater (P < 0.001). At 12 months, there were no differences in functional outcomes (International Prostate Symptom Score, maximum urine flow rate). Despite comparable prostate volumes at 12 months (P = 0.864), the prostate-specific antigen level in the thulium fiber laser enucleation of the prostate group (0.5 ± 0.5 ng/mL) was lower than in the transurethral resection of the prostate group (1.1 ± 1.0 ng/mL; P < 0.001). Hemoglobin and serum sodium decrease was lower in the thulium fiber laser enucleation of the prostate group (1.01 ± 0.4 g/dL and 1.1 ± 1.1 mmol/L) than in the transurethral resection of the prostate group (1.8 ± 0.8 g/dL and 4.1 ± 1.1 mmol/L; P < 0.001). Urinary incontinence rates at 12 months were comparable (P = 0.316). Conclusions: Thulium fiber laser enucleation of the prostate with novel thulium fiber laser in patients with smaller prostate glands (<80 cc) is comparable to transurethral resection of the prostate in voiding parameters improvement and complication rates. At the same time, the technique allows for a more substantial prostate-specific antigen decrease, indicating more complete removal of adenoma.
