Review
Neuroendocrine prostate cancer (NEPC) is a rare subtype of prostate cancer (PCa) that usually results in poor clinical outcomes and may be accompanied by paraneoplastic syndromes (PNS). NEPC is becoming more frequent. It can initially manifest as PNS, complicating diagnosis. Therefore, we reviewed the literature on the different PNS associated with NEPC. We systematically reviewed English-language articles from January 2017 to September 2023, identifying 17 studies meeting PRISMA guidelines for NEPC and associated PNS. A total of 17 articles were included in the review. Among these, Cushing's Syndrome (CS) due to ectopic Adrenocorticotropic hormone (ACTH) secretion was the most commonly reported PNS. Other PNS included syndrome of inappropriate Anti-Diuretic Hormone secretion (SIADH), Anti-Hu-mediated chronic intestinal pseudo-obstruction (CIPO), limbic encephalitis, Evans Syndrome, hypercalcemia, dermatomyositis, and polycythemia. Many patients had a history of prostate adenocarcinoma treated with androgen deprivation therapy (ADT) before neuroendocrine features developed. The mean age was 65.5 years, with a maximum survival of 9 months post-diagnosis. NEPC is becoming an increasingly more common subtype of PCa that can result in various PNS. This makes the diagnosis and treatment of NEPC challenging. Further research is crucial to understanding these syndromes and developing standardized, targeted treatments to improve patient survival.

INTRODUCTION
Transurethral resection of the prostate (TURP) remains the gold standard for treatment of benign prostatic hyperplasia (BPH). Yet, the introduction of lasers for the treatment of LUTS due to BPO has dramatically changed the surgical landscape of benign prostatic obstruction (BPO) treatment. Recently, "en-bloc" techniques have shown to prove advantageous in terms of better visualization, more prompt identification of the surgical capsule and the correct plane to dissect. Herein we provide a comprehensive overview of available series of en-bloc enucleation of the prostate, focusing on surgical techniques, perioperative and functional outcomes.
EVIDENCE ACQUISITION
A systematic review of the literature was performed according to PRISMA recommendations and was conducted on surgical techniques and perioperative outcomes of minimally invasive en-bloc surgery for prostate adenoma detachment.
EVIDENCE SYNTHESIS
Overall, 16 studies with 2750 patients between 2003 and 2019 were included. Specific technical nuances have been described to maximize perioperative outcomes of en-bloc prostatic enucleation, including early apical release, horse-shape incisions, inverted U-shape tractions and low power. Overall, regardless of the energy employed, en-bloc prostatic enucleation achieved favorable outcomes including low risk of major complications and quality of life improvement. However, a great heterogeneity of study design, patients' inclusion criteria, prostate volume and en-bloc surgical strategy was found.
CONCLUSIONS
En-bloc endoscopic enucleation of the prostate has been shown to be technically feasible and safe, with potential technical advantages over the classic three-lobe technique. Larger comparative studies are needed to evaluate the ultimate impact of the en-bloc approach on postoperative outcomes, in light of the surgeon's learning curve.

BACKGROUND
Benign prostatic hyperplasia (BPH) is a noncancerous enlargement of the prostate that commonly affects older people with prostates and may lead to obstructive urinary symptoms. Symptoms may initially be mild but tend to worsen over time. Prostatic artery embolization (PAE) is an endovascular procedure to treat BPH, wherein an interventional radiologist inserts a catheter into the patient to inject tiny particles intended to reduce blood flow to the enlarged prostate, causing it to shrink in size. We conducted a health technology assessment on PAE for people with BPH, which included an evaluation of effectiveness, safety, cost-effectiveness, the budget impact of publicly funding PAE, and patient preferences and values.
METHODS
We performed a systematic literature search of the clinical evidence. We assessed the risk of bias of each included study using the Cochrane Risk of Bias tool for randomized controlled trials (RCTs) and the Risk of Bias in Nonrandomized Studies-of Interventions (ROBINS-I) tool for observational studies. We assessed the quality of the body of evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. We performed a systematic review of the economic literature. We then assessed the cost-effectiveness of PAE compared with alternative treatments (i.e., transurethral resection of the prostate [TURP] or open simple prostatectomy [OSP]) using a Markov microsimulation model. The analysis was conducted from the Ontario Ministry of Health perspective over a time horizon of 6.5 years. We also analyzed the budget impact of publicly funding PAE in people with moderate to severe BPH in Ontario.
RESULTS
We included six studies in our systematic review. Four RCTs and one observational study compared PAE with TURP, and one observational study compared PAE with OSP. All studies had considerable risk-of-bias concerns. PAE may improve BPH symptoms and urodynamic measures, but we are uncertain whether PAE achieves better results than TURP (GRADE: Very low to Low). Compared with TURP, PAE may result in higher patient satisfaction and fewer adverse events (GRADE: Not assessed). Compared with OSP, PAE may result in smaller improvements in BPH symptoms and urodynamic measures and may lead to fewer adverse events, but the evidence is very uncertain (GRADE: Very low).We did not find any published cost-effectiveness studies in the economic literature review. Our primary economic evaluation showed that, compared with TURP, PAE has an incremental cost of $328 (95% CrI: -$686 to $1,423) and a very small incremental quality-adjusted life-year (QALY) of 0.007 (95% CrI: -0.004 to 0.018). The resulting incremental cost-effectiveness ratio (ICER) of PAE versus TURP is $44,930 per QALY gained. At the commonly used willingness-to-pay values of $50,000 and $100,000 per QALY, the cost-effectiveness of PAE is uncertain (52% and 68% probability, respectively, of being cost-effective compared with TURP). In a scenario analysis, we compared PAE with OSP for individuals with large prostates (who may be ineligible for TURP). We found that PAE is less costly (-$1,231; 95% CrI: -$2,457 to $69) and less effective (-0.12 QALYs; 95% CrI: -0.18 to -0.04). The resulting ICER of PAE versus OSP is $10,241 saved per QALY lost. At the commonly used willingness-to-pay value of $50,000 per QALY, PAE is unlikely to be cost-effective (2% probability of being cost-effective compared with OSP). Assuming a low uptake (i.e., an additional 10 to 50 procedures per year in years 1 to 5), we estimated that publicly funding PAE in Ontario would lead to an additional cost of about $11,400 over the next 5 years.People we spoke with who have lived experience with BPH reported on the negative impact it can have on their quality of life. Those who had received PAE reported a positive experience with the procedure and meaningful improvement in their symptoms.
CONCLUSIONS
Prostatic artery embolization may improve BPH symptoms and urodynamic measures, but we are uncertain if the procedure results in similar outcomes to those of TURP. Based on one observational study, PAE may result in smaller improvements compared with OSP, but we are very uncertain of the evidence. Compared with TURP and OSP, PAE may result in fewer adverse events. Longer-term comparative studies are needed to assess the durability and long-term adverse events of PAE, the potential need for reintervention after PAE, and how PAE compares with other available BPH treatment options.We found the cost-effectiveness of PAE compared with TURP to be uncertain. Also, PAE is unlikely to be cost-effective compared with OSP. If PAE is publicly funded in Ontario, the budget impact is estimated to be small over the next 5 years.People who have lived experience with BPH reported that PAE improves quality of life and reduces negative symptoms of BPH.

PURPOSE
Laser endoscopic enucleation of the prostate (EEP) for benign prostatic obstruction has become increasingly prevalent worldwide. Considering the medical cost-savings and concomitantly fewer nosocomial infections, the feasibility of same-day postoperative discharge of patients who have undergone laser EEP in terms of its safety and effectiveness has become a subject matter of growing interest. We aimed to review those studies focussing on day-case surgery (DCS) in patients undergoing laser EEP.
METHODS
A systematic search was conducted using PubMed-MEDLINE and Web of Science databases until October 2022 with the following search terms: "same day discharge AND laser enucleation of the prostate", "day-case AND laser enucleation of the prostate", "same day surgery AND laser enucleation of the prostate" and "one day surgery AND laser enucleation of the prostate" by combining PICO (population, intervention, comparison, outcome) terms. We identified 15 eligible studies.
RESULTS
While 14 of the studies focussed on holmium laser EEP, one focused on thulium laser vapoenucleation of the prostate. We observed an improvement in functional parameters in all studies we reviewed, and DCS success and readmission rates ranged between 35.3-100% and 0-17.8%, respectively. The complication rates varied between 0 and 36.7%, most of the complicatons were Clavien-Dindo (CD) I and II. CD ≥ III complications did not significantly differ between same day discharge (SDD) and non-SDD groups in the studies.
CONCLUSION
Laser EEP is feasible and promising DCS treatment option delivering improved functional parameters compared to baseline values, and lower perioperative complication and readmission rates in certain patients.

Review
INTRODUCTION
Prostate cancer is the most common cancer amongst men in the UK. Treatments for malignant ureteric obstruction consist of percutaneous nephrostomy, ureteric stent insertion, or occasionally other forms of urinary diversion. Our aim was to look at the outcomes of percutaneous nephrostomy (PCN) in patients with advanced prostate cancer and to look at the impact on patient's general health, quality of life, life expectancy and complications after PCN insertion.
MATERIAL AND METHODS
A systematic review of the literature was done for all prospective English language articles on PCN in patients with prostate cancer using PubMed, MEDLINE, EMBASE, Scopus, CINAHL, Cochrane library, Clinicaltrials.gov, Google Scholar and individual urological journals from inception to August 2017. While studies involving prostate cancer patients were included, studies on all other mixed pelvic malignancies were excluded.
RESULTS
Seven articles met the inclusion criteria. There were 184 patients, with a mean age of 70 years (range: 51-94 years). PCN was performed for ureteric obstruction due to advanced prostate cancer, patients underwent unilateral (n = 66) or bilateral PCN (n = 118) with conversion to an antegrade stent in 25 patients. Their post-PCN survival varied between 4-31 months and this was longer if they were hormone naïve or showed a good recovery in their renal function. Although the complication rates were low (1-3%), patients spend a high proportion of their lives in the hospital.
CONCLUSIONS
PCNs should only be pursued after thoughtful counselling regarding further treatment options and prognosis as these patients with advanced malignancies seem to have reduced survival duration and spend a significant amount of time in hospital.

Review
INTRODUCTION
One recent addition to different lasers used for endoscopic enucleation of the prostate is the thulium fiber laser (TFL). The purpose of this systematic review is to present the feasibility, safety and efficacy of TFL Enucleation of the Prostate (ThuFLEP).
EVIDENCE ACQUISITION
PubMed, Scopus and Cochrane primary databases were systematically screened. The search strategy used the PICO (Patients, Intervention, Comparison, Outcome) criteria. Patients should be adults with benign prostatic obstruction (BPO) undergoing ThuFLEP. While comparative studies reporting comparison of ThuFLEP to other BPO treatments were included, cohort studies with no comparison group were also accepted. Outcomes including enucleation time and complication rates were reported.
EVIDENCE SYNTHESIS
Twelve studies met all the predefined criteria and were included in the final qualitative synthesis. Mean operative time and enucleation time ranged from 46.6±10.2 to 104.5±33.6 and from 38.8±17.9 to 66.0±24.9 minutes, respectively. Most of the complications were Grade I or Grade II ones. Although TFL was found to present some advantages over older BPO treatments, its outcomes were comparable with other endoscopic enucleation approaches.
CONCLUSIONS
ThuFLEP seems to be a feasible, safe and efficient approach for BPO symptoms management. Limited evidence showed that although ThuFLEP was associated with a reduced total operative time, it was also associated with worse IPSS improvement at 1-year follow-up, when compared with MOSES Holmium Laser Enucleation of the Prostate (HoLEP). These findings confirm the well-established opinion that the enucleation technique itself is more important than the technology which is used.

PURPOSE
The exact molecular and cellular processes that cause benign urological diseases in the stromal and epithelial components of the urinary tract are yet unknown. Reviewing and analyzing the data linking microRNAs (miRNAs) expression in the pathophysiology of benign urological conditions, including overactive bladder (OAB), bladder outlet obstruction (BOO), bladder pain syndrome/interstitial cystitis (BPS/IC), and Lower urinary tract dysfunction (LUTD) is the objective of the current systematic review.
MATERIALS AND METHODS
Evidence including all case-control, cohort, and cross-sectional studies that measure participants' MicroRNA as a biomarker for benign urological diseases has been gathered On January 2024, through searching MEDLINE via PubMed, Scopus, Web of Science, Embase, and ProQuest databases. Studies considered eligible that present information on the reference Gene, profile type, and serum levels of microRNA from patients diagnosed with benign urological disease including benign prostate hyperplasia (BPH) or benign prostate enlargement (BPE), overactive bladder (OAB), and bladder outlet obstruction (BOO). These studies appraised by the quality assessment checklist of Joanna Briggs Institute (JBI).
RESULTS
A total of 4,587 records related to miRNAs in urological diseases were retrieved. Of these, we identified 28 records for our systematic study. The most frequently associated miRNA was 92a-3p identified which was found upregulated in OAB diagnosis. In BOO, miR-146a-5p was identified to be upregulated. miR-146a-5p was upregulated in BO, and for other benign conditions, different miRNAs were reported. 491-5p miRNAs were found deregulated in OAB-related studies. We expected other miRNAs to have the same trend in the OAB studies. InSUI miR-93 was the most frequent downregulated miRNA. The other reported miRNAs had similar frequencies.
CONCLUSION
When it comes to the early detection and treatment of benign urological conditions, 92a-3p, miR-21, miR-199a-5p, and miR-146a-5p, and 491-5p have the potential to be employed as both a biomarker and a therapeutic target. The creation of pre-RNA or anti-RNA molecules within carrier vehicles that may be safely administered to patients should be made possible by technological advancements.

JAMA Internal Medicine Jan 2018Overuse of medical care is a well-recognized problem.
IMPORTANCE
Overuse of medical care is a well-recognized problem.
OBJECTIVE
To identify and highlight original research articles published in 2016 that are most relevant to understanding medical overuse or strategies to reduce it.
EVIDENCE REVIEW
A structured review of English-language articles on PubMed published in 2016 coupled with examination of tables of contents of high-impact journals to identify articles related to medical overuse in adults. These articles were appraised for their importance to medicine.
FINDINGS
This study considered 2252 articles, 1224 of which addressed medical overuse. Of these, 122 were deemed most relevant based on originality, methodologic quality, and number of patients potentially affected. The 10 most influential articles were selected by author consensus. Select findings from the studies include the lack of benefit of transesophageal echocardiography in the workup of cryptogenic stroke, increasing use of computed tomography in the emergency department from 2.2% to 9.4% from 2001 to 2010, and carotid ultrasonography and revascularization being performed for uncertain or inappropriate indications with 95% frequency. Likewise, services for which harms are likely to outweigh benefits include treatment for early-stage prostate cancer, which provides no mortality benefit but increases absolute risk of erectile dysfunction by 10% to 30%, oxygen for patients with moderate chronic obstructive pulmonary disease, surgery for meniscal tear with mechanical symptoms, and nutritional interventions for inpatients with malnutrition. This review highlights 2 methods for reducing overuse: clinician audit and feedback with peer comparison for antibiotic use (reduction in inappropriate antibiotic use from 20% to 4%) and a practical and sensible shared decision-making tool for low-risk chest pain (reduction in emergency department workup from 52% to 37%).
CONCLUSIONS AND RELEVANCE
The body of empirical work continues to expand related to medical services that are provided for inappropriate or uncertain indications. Engaging patients in conversations aimed at shared decision making and giving practitioners feedback about their performance relative to peers appear to be useful in reducing overuse.

Review
INTRODUCTION
This study aimed to describe the effects of bladder function following radiotherapy for localized prostate cancer by performing a systematic review on studies reporting on urodynamic findings after radiotherapy.
METHODS
This systematic review was conducted in accordance with PRISMA guidelines. The review protocol was registered at PROSPERO (CRD42021229037). A systematic search was conducted using PubMed, Cochrane Library, Scopus, and OVID Embase. Studies were included if they involved men who underwent urodynamic studies following radiotherapy for localized prostate cancer. A total of 798 articles were screened and five articles included. A qualitative analysis was performed.
RESULTS
Bladder compliance appears to be impaired following radiotherapy, especially with longer followup. Impaired bladder compliance was reported in 18.8-62.5% of patients following radiotherapy. Bladder capacity was found to be statistically significantly lower following radiotherapy compared to pre-radiotherapy, and when compared with patients who did not undergo pelvic radiotherapy. Bladder outlet obstruction (BOO) persists post-radiotherapy in most patients at three and 18 months post-radiotherapy. De novo detrusor overactivity (DO) of 13.3% has been reported at 18 months post-radiotherapy. This review is limited by the absence of level I/II studies.
CONCLUSIONS
Radiotherapy for localized prostate cancer results in decreased bladder compliance and capacity demonstrated on urodynamic studies. Resolution of BOO appears less likely in comparison to series on radical prostatectomy. De novo DO may develop following radiotherapy, especially with longer followup. With only low level of evidence studies available at present, further high-quality, prospective studies are important to elucidate the impact of radiotherapy on bladder and urethral function.

Meta-Analysis
Anterograde ejaculation preservation after endoscopic treatments in patients with bladder outlet obstruction: systematic review and pooled-analysis of randomized clinical trials.
INTRODUCTION
Despite the high rate of resolution, ejaculatory dysfunction still is the most common side effect related to surgical treatment of bladder outlet obstruction (BOO). The aim of the present systematic review was to compare several technological treatment modalities for the management of lower urinary tract symptoms/BOO in terms of functional and sexual outcomes.
EVIDENCE ACQUISITION
All English language randomized controlled trials assessing the impact of different endoscopic treatments for BOO were evaluated. We followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) statement to evaluate PubMed®, Scopus®, and Web of Science™ databases (up to June 2019).
EVIDENCE SYNTHESIS
Our electronic search identified a total of 2221 papers in PubMed, Scopus, and Web of Science. Of these, 142 publications were identified for detailed review, which yielded 21 included in the present systematic review. All groups appeared similar with regards to preoperative IPSS/AUA Score, Qmax, and prostate volume (cc). Patients undergoing endoscopic treatments using ThuLEP, Greenlight or Prostate Artery Embolization techniques had lower-but not statistically significant- relative risk (RR) of retrograde ejaculation compared with conventional transurethral resection of the prostate (TURP) (RR: 0.90; P=0.35; RR: 0.71; P=0.1; RR0.73; P=0.11). Efficacy of those techniques was equal to TURP.
CONCLUSIONS
Data reporting anterograde ejaculation preservation after endoscopic treatment in patients with benign prostatic enlargement are sparse and heterogeneous. Pooled analyses suggest that new technological alternatives to conventional TURP might improve sexual outcomes, especially for non-ablative treatments.
