Abstract
Background
Prostate cancer can be detected incidentally in patients undergoing transurethral resection of the prostate for benign prostatic hyperplasia. Therefore, it is very important that the transurethral resection of the prostate specimen is evaluated carefully for accurate grading and staging. The aim of this study was to investigate the frequency of incidental prostate cancer and its relationship with clinicopathological findings.
Methods
The study included a total of 900 patients, who underwent transurethral resection of the prostate for benign prostatic hyperplasia treatment between June 2010 and June 2020. Patient age, prostate-specific antigen (PSA) levels and resected prostate weight were assessed, and the tumor stage, Gleason grade group, lymphovascular and perineural invasion status were also evaluated in the incidental prostate cancer group. The association between these parameters and prostate cancer detection was analyzed.
Results
Incidental detection of prostate cancer was determined at the rate of 13.3%. The incidental prostate cancer group had a significantly higher mean age and PSA levels compared to the benign prostatic hyperplasia group. The weight of the resected specimen had no impact on the incidence of incidental prostate cancer. Of the total 120 incidental prostate cancer cases, 59 (49.2%) were stage T1a and 61 (50.8%) were stage T1b. No significant difference was determined between the T1 stages and age distribution, but a statistically significant difference was determined in the other clinicopathological parameters.
Conclusions
The results of this study demonstrated that the incidence of incidental prostate cancer detection was related to age and PSA levels and increased, especially in those aged ≥ 60 years and/or PSA level ≥ 4 ng/mL. To avoid overlooking incidental prostate cancer in these patients, it can be recommended that material is sufficiently sampled and carefully evaluated, and when necessary, all resected specimens are examined. Although no significant correlation was determined between specimen weight and the incidence of incidental prostate cancer, as a significant difference was determined in T1 stages, this suggests that the amount of material evaluated could change the sub-stage.

Abstract
Prostate cancer can be detected incidentally after surgical therapy for benign prostatic obstruction such as holmium laser enucleation of the prostate (HoLEP), thus called incidental prostate cancer (iPCa). We aimed to review the studies on iPCa detected after HoLEP and investigate its prevalence. A detailed search of original articles was conducted via the PubMed-MEDLINE, Web of Science, Wiley Online Library and Cochrane Library databases in the last 10 years up to 1 May 2021 with the following search string solely or in combination: "prostate cancer", "prostate carcinoma", "holmium laser enucleation of the prostate" and "HoLEP". We identified 19 articles to include in our analysis and divided them into six main categories: HoLEP versus open prostatectomy and/or transurethral resection of the prostate in terms of iPCa, oncological and functional outcomes, the role of imaging modalities in detecting iPCa, predictive factors of iPCa, the role of prostate-specific antigen kinetics in detecting iPCa and the management of iPCa after HoLEP. We found that the iPCa after HoLEP rate ranges from 5.64% to 23.3%. Functional and oncological outcomes were reported to be encouraging. Oncological treatment options are available in a wide range.

Abstract
PURPOSE To determine the histological validity of the tissue acquired during aquablation of the prostate. PATIENTS AND METHODS Prostatic tissue of 12 patients that consecutively underwent aquablation for benign prostatic enlargement was systematically examined. Histological examination was performed by two experienced uropathologists using a digital slide scanner and slide viewer software (Pannoramic 250 and Case Viewer 2.3, 3D Histech, Hungary). The surface areas of the assessable glands were examined and set in relation to the total surface area of the material available for histology and to the patient's total prostate volume. Examinations were performed analogously in ten consecutive patients undergoing transurethral resection of the prostate (TURP) to facilitate interpretation of the results. Data were analyzed using descriptive statistics. RESULTS A median of 4.06% (range 1.43-7.5%) of the preoperative total prostate volume (median 64.5 ml (range 40-80 ml)) was obtained for histological examination by aquablation. Due to severe mechanical destruction and fragmentation, only a proportion of 0.43% (0.06-1.79%) of this tissue represented histologically assessable glands. Therefore, roughly 0.017% of the total prostatic volume was available for a reliable histological examination. In comparison, 32.5% (6.67-37.5%) of the total prostate volume was removed by TURP and 22.86% (7.45-40.57%) of this tissue represented informative prostatic glands, corresponding to 7.43% of the total prostate volume. CONCLUSION Histological significance of the tissue obtained by aquablation of the prostate is very limited. Costs and effort of the histological examination must, therefore, be weighed critically against the limited informative value.

Abstract
PURPOSE The purpose of the study was to investigate the incidence of perioperative hypothermia in urology patients undergoing transurethral resection with either TURis or transurethral resection of the prostate method and to recognize the risk factors that were responsible for the occurrence of hypothermia intraoperatively in these patients. METHODS It was a randomized prospective study. A total of 168 patients, according to American Society of Anesthesiologists physical status I-III, were scheduled for transurethral resection either with TURis or transurethral resection of the prostate method. We measured the core body temperature before (preoperative), during (perioperative) and after (postoperative) the surgery. Age, body mass index, American Society of Anesthesiologists score, duration of surgery, preoperative prostatic volume, and vital signs were also recorded. RESULTS The prevalence of inadvertent hypothermia was 64.1% for the TURis group and 60% for the transurethral resection of the prostate group. Hypothermic patients in TURis group were significantly older (87.7 ± 1.7 vs 68 ± 6.7 years, p < 0.05) and had lower body mass index (26.9 ± 3.6 vs 29.2 ± 2.7, p < 0.05), while hypothermic patients in the transurethral resection of the prostate group were significantly older (86 ± 1.1 vs 70 ± 7.4 years, p < 0.05) and had notably higher duration of surgery (140.6 ± 28.9 vs 120.3 ± 14.3 min, p < 0.05) than normothermic patients. CONCLUSION Perioperative inadvertent hypothermia among urology patients who underwent transurethral resection with both TURis and transurethral resection of the prostate method is of high incidence. We recommend monitoring of the temperature of core body of all these patients, especially those with advanced age and lower body mass index.

Abstract
BACKGROUND With the progress of surgical techniques and instruments, various minimally invasive surgical therapies were developed to treat benign prostatic hyperplasisa (BPH). However, the efficacy and safety of different transurethral procedures for the treatment of BPH are still undefined. METHOD A systematic search was performed for all randomized controlled trials (RCTs), which compared the transurethral procedures for BPH from 1995 to 2016. The clinical baseline characteristics, International Prostate Symptom Score (IPSS), quality of life (QoL), postvoid residual (PVR), maximum flow rate (Qmax), short-term and long-term complications were analyzed using RevMan and ADDIS software. RESULT Eighty-eight randomly controlled trials and fifteen procedures were included in the network meta-analysis. HoLEP greatly inproved PVR. TmLRP had the best efficacy in improving QoL score. Diode laser vaporization of prostate was superior in improving IPSS and Qmax. Diode laser through vaporization required the shortest time in catheterization, while Nd:YAG was the longest procedure. For the hospitalization time, TUR was the longest and HoLEP was the shortest. TmLRP was related to the lowest postoperative hemoglobin decrease. TmLEP had the least rates of occurrence of hematuria, reoperation and erectile dysfunction. HoLEP was the best choice to reduce the incidence of recatheterization, urinary retention, urinary tract infection, stress urinary incontinence and retrograde ejaculation. The complications such as blood transfusion, urethral stricture, bladder neck contracture were relatively rare in the patients who underwent diode laser vaporization of prostate. CONCLUSION Compared with other transurethral procedures, thulium, holmium and diode lasers were associated with better efficacy and fewer complications.

Abstract
This study compared the safety and effectiveness of the diode laser and thulium laser during prostate transurethral vaporesection for treating benign prostate hyperplasia (BPH). We retrospectively analyzed 205 patients with BPH who underwent a diode laser or thulium laser technique for prostate transurethral vaporesection from June 2016 to June 2017 and who were followed up for 3 months. Baseline characteristics of the patients, perioperative data, postoperative outcomes, and complications were compared. We also assessed the International Prostate Symptom Score (IPSS), quality of life (QoL), maximum flow rate (Qmax), average flow rate (AFR), and postvoid residual volume (PVR) at 1 and 3 months postoperatively to evaluate the functional improvement of each group. There were no significant differences between the diode laser and thulium laser groups related to age, prostate volume, operative time, postoperative hospital stays, hospitalization costs, or perioperative data. The catheterization time was 3.5 ± 0.8 days for the diode laser group and 4.7 ± 1.8 days for the thulium laser group (p < 0.05). Each group had dramatic improvements in IPSS, QoL, Qmax, AFR, and PVR compared with the preoperative values (p < 0.05), although there were no significant differences between the two groups. Use of both diode laser and thulium laser contributes to safe, effective transurethral vaporesection in patients with symptomatic BPH. Diode laser, however, is better than thulium laser for prostate transurethral vaporesection because of its shorter catheterization time. The choice of surgical approach is more important than the choice of laser types during clinical decision making for transurethral laser prostatectomy.
