Simple prostatectomy (SP) can be utilized for patients with large prostates with lower urinary tract symptoms. Prostate artery embolization (PAE) does not have robust clinical evidence to support its use in treating urinary symptoms; however, it is an effective treatment for refractory hematuria from a prostatic source. There have been limited papers regarding preoperative PAE prior to SP. However, there are no papers regarding the feasibility of delayed SP after PAE. We present, to our knowledge, the first paper demonstrating a successful robot-assisted SP years after a PAE in a patient with a 380g prostate with recurrent refractory gross hematuria.

UNASSIGNED: More and more new surgical procedures for the treatment of benign prostate hyperplasia (BPH) are proposed creatively. However, the existing clinical evidence shows that the effectiveness and safety of various procedures exist inconsistent.
UNASSIGNED: The randomized controlled trials comparing the international prostate score, length of hospital stay, maximum urinary flow rate, operation time, and complication rates of prostatic artery embolization (PAE), Greenlight-XPS Laser prostate vaporization procedure (GLL PVP), diode laser enucleation of prostate (DILEP) and plasmakinetic resection of the prostate (PKRP), transurethral resection of the prostate (TURP) in patients with BPH were screened out in databases. The primary outcome was pooled using a restricted maximum likelihood-based random-effect model and inverse variance-based fixed-effect model. Cochrane Q statistics and I2 statistics were computed to quantify between-study heterogeneity. The risk of bias of each included study was assessed using the revised Cochrane risk of bias tool.
UNASSIGNED: This meta-analysis ultimately included 14 original research papers, with 1,940 participants enrolled. Eight studies were considered to be at moderate risk of bias, while the others were at mild risk of bias. Although the improvement in functional outcome of the DILEP procedure was equivalent to that of the PKRP procedure, the DILEP procedure group had fewer hospital stays than the PKRP group (P=0.01). In addition, even though the performance of the GLL PVP procedure in the improvement of functional outcome was inferior to the counterpart of TURP (P=0.64), it had a much fewer hospital stays (P=0.01). Moreover, there is still insufficient evidence for the improvement of subjective functional indicators of postoperative patients with PAE compared with TURP [international prostate symptom score (IPSS): P=0.73; IPSS QoL: P=0.91], but achieved less satisfactory objective functional outcomes (Qmax: P=0.06; PVR: P=0.00).
UNASSIGNED: New surgical procedures such as GLL PVP, PAE, and DILEP were safer than traditional TURP procedures. However, it is not superior to traditional surgery in the improvement of clinical symptoms. In clinical practice, the pros and cons of the new operation and the traditional operation should be carefully weighed, and the operation that is most suitable for the patient\'s condition should be selected.

UNASSIGNED: Although the efficacy and safety of monotherapy in the treatment of benign prostatic hyperplasia (BPH) have been established clinically, the efficacy and safety of dutasteride and finasteride have not been compared. The aim was to systematically evaluate the efficacy and safety of the two drugs in the treatment of BPH to provide medical evidence for clinical treatment.
UNASSIGNED: A search of relevant articles was conducted using the electronic databases PubMed, Embase, Medline, Cochrane Library, China Academic Journals Full-text Database (CJFD), Chinese Science and Technology Journal Database (VIP) and Wanfang Database. Randomized controlled trials (RCTs) comparing the efficacy of finasteride (control group) with that of dutasteride (experimental group) in the treatment of BPH with respect to the International Prostate Symptom Score (IPSS), the maximum urinary flow rate (Qmax), prostate volume (PV), quality of life (QOL), serum prostate-specific antigen (PSA) level and adverse drug reactions (ADRs) after medication were strictly evaluated and considered for inclusion. Rev Man 5.4 software was used for the meta-analysis.
UNASSIGNED: A total of 8 RCTs were included, with a total of 2,116, patients. The meta-analysis showed that compared with finasteride, dutasteride can effectively improve the Qmax of patients with BPH [mean difference (MD) =0.32; 95% confidence interval (CI): (0.01, 0.63); P=0.04]. There was no significant difference in reducing IPSS [MD =0.13; 95% CI: (-0.55, 0.82); P=0.70], improving PV [MD =-1.25; 95% CI: (-3.30, 0.79); P=0.23], reducing QOL [MD =-0.44; 95% CI: (-0.93, 0.05); P=0.08] and serum PSA level [MD =-0.04; 95% CI: (-0.15, 0.07); P=0.50], and the occurrence of ADRs [relative risk (RR) =-0.01; 95% CI: (-0.05, 0.04); P=0.72], there was no significant difference.
UNASSIGNED: Dutasteride is better than finasteride in improving the Qmax of patients with BPH. There was no statistically significant difference in symptoms, PV, PSA, QOL, or adverse reactions. Dutasteride is an effective and safe treatment for BPH. Due to the limitations of the methodological quality and sample size of the included studies, this conclusion needs to be verified by stratified RCTS with high volumes and long follow-up times.

A 66-years old male patient presents with lower urinary tract symptoms, mostly due to obstructive symptoms, and an enlarged prostate with 80 cm3, with a broad-based median lobe, suggestive of benign prostatic obstruction (BPO). Trans-urethral resection of the prostate (TURP) was proposed. However, the patient desired to preserve ejaculatory function and was afraid of a potential negative impact on erectile function. Thus, the patient inquired about minimally invasive therapies (MITs) as alternatives to TURP. In this review, currently available MITs for BPO are described including prostatic artery embolization, water vapor thermal therapy (Rezum®), prostatic urethral lift, iTIND® (temporary implantable device) and aquablation (Aquabeam®). Focus is given on the description of the technique, level of evidence and advantages over conventional surgical options.

Prostatic artery embolization (PAE) has been established as a routine treatment for symptomatic benign prostatic hyperplasia (BPH) all over the world. With increasing clinical experience in the last decade, investigators have sufficient data to assess predictive factors with the purpose to guide patient selection and counseling for PAE or to individualize therapeutic plans after PAE. This paper is a comprehensive review to introduce the concept of clinical predictors and give a systemic classification of various predictive factors in PAE. The authors review each individual factor and its predictive capability and discuss the possible reasons for the inconsistent or conflicting findings in the literature. Based on current evidence, the baseline prostate volume, in particular the transition zone volume and transition zone index; 24 h post-PAE prostate-specific antigen (PSA) level; and prostate infarction and prostate volume reduction at 1-3 months have potential in prediction of treatment outcomes. Patients with Adenomatous-dominant BPH or with indwelling bladder catheter before PAE may have more benefits from PAE. Baseline intravesical prostatic protrusion (IPP), C-reactive protein (CRP) level at 48 h and early detection of prostate infarct at 1 day and 1 week after PAE need further investigating.

Background: Previous meta-analysis evaluated a limited number of parameters regarding the comparison of BTPV and TURP for BPH. Method: PubMed, Embase and Cochrane Library were searched for literature comparing BTPV with TURP. Data of efficacy (IPSS, Qmax, PVR and QoL) and safety were extracted and evaluated using either SMD or OR with 95% CI. All analyses were performed by RevMan 5.3. Results: Eleven trials with 1690 patients were selected. Compare to BTPV, TURP had better 6-month IPSS (SMD=0.36, 95% CI 0.08 to 0.63), better 1- (SMD=-0.38, 95% CI -0.63 to -0.12), 6- (SMD=-0.73, 95% CI -0.99 to -0.46) and 12-month Qmax (SMD=-0.47, 95% CI -0.85 to -0.10), better 6-month PVR (SMD=1.18, 95% CI 0.87 to 1.48), as well as better 3- (SMD=-0.24, 95% CI -0.48 to -0.01) and 6-month QoL (SMD=-0.62, 95% CI -0.91 to -0.33). However, BTPV had shorter catheterization time (SMD=-0.96, 95% CI -1.12 to -0.79) and hospital stay (SMD=-0.71, 95% CI -0.89 to -0.53), less hemoglobin decrease (SMD=-1.09, 95% CI -1.27 to -0.91) and virtually shorter operation time (SMD=-0.15, 95% CI -0.31 to 0.01). Moreover, BTPV had fewer occurrence of overall complications (OR=0.52, 95% CI 0.40 to 0.69), Clavien III-IV complications (OR=0.61, 95% CI 0.37 to 1.02), blood transfusion (OR=0.25, 95% CI 0.09 to 0.69), hematuria (OR=0.27, 95% CI 0.13 to 0.56) and capsular perforation (OR=0.19, 95% CI 0.08 to 0.48). Subgroup analysis indicated BTPV and bipolar TURP had similar total complications (OR 1.08, 95% CI 0.40-2.88, P=0.88) and Clavien III-IV complications (OR 1.42, 95% CI 0.36-5.57, P=0.61) and blood transfusion rate (OR 0.28, 95% CI 0.04-1.73, P=0.17). Conclusion: Both TURP and BTPV could significantly improve IPPS, Qmax, PVR and QoL. TURP had slightly better short-term efficacy, while BTPV had better safety. However, subgroup analysis found bipolar TURP and BTPV had similar safety.

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).
Systematic review and meta-analysis, conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement.
PubMed, EMBASE, the Cochrane Library until October 2018.
Randomised controlled trials and prospective studies comparing the safety and efficacy of PVP versus TURP for LUTS manifesting through BPH.
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).
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.
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.

This review discusses current and developing indications for angioembolization (AE) techniques in urology cases, including trauma and non-trauma uses for kidney, prostate, and bladder conditions. AE methods, complications and technical and clinical outcomes are outlined for each indication for the purpose of aiding urologists in selecting ideal candidates for this procedure.

Benign prostatic hyperplasia (BPH) is a common pathology causing lower urinary tract symptoms (LUTS) and may significantly impact quality of life. While transurethral resection of the prostate (TURP) remains the gold standard treatment, there are many evolving technologies that are gaining popularity. Photoselective vaporization of the prostate (PVP) is one such therapy which has been shown to be non-inferior to TURP. We aimed to review the literature and discuss factors to optimise patient outcomes in the setting of PVP for BPH. A comprehensive search of the electronic databases, including MEDLINE, Embase, Web of Science and The Cochrane Library was performed on articles published after the year 2000. After exclusion, a total of 38 papers were included for review. The evolution of higher powered device has enabled men with larger prostates and those on oral anticoagulation to undergo safely and successfully PVP. Despite continued oral anticoagulation in patients undergoing PVP, the risk of bleeding may be minimised with 5-Alpha Reductase Inhibitor (5-ARI) therapy however further studies are required. Pre-treatment with 5-ARI\'s does not hinder the procedure however more studies are required to demonstrate a reliable benefit. Current data suggests that success and complication rate is largely influenced by the experience of the operator. Post-operative erectile dysfunction is reported in patients with previously normal function following PVP, however those with a degree of erectile dysfunction pre-operatively may see improvement with alleviation of LUTS.
