Meta-Analysis Review
Lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) is common in adult men and can impair erectile function (EF). It was believed surgical treatments for this illness can improve EF due to the relief of LUTS while they were also reported harmed EF as heating or injury effect. Current network meta-analysis aimed to elucidate this discrepancy.Randomized controlled trials (RCTs) were identified. Direct comparisons were conducted by STATA and network meta-analysis was conducted by Generate Mixed Treatment Comparison. Random-effects models were used to calculate pooled standard mean difference and 95% confidence intervals and to incorporate variation between studies.Eighteen RCTs with 2433 participants were analyzed. Nine approaches were studied as transurethral resection of the prostate (TURP), plasmakinetic resection of the prostate (PKRP), plasmakinetic enucleation of the prostate (PKEP), Holmium laser enucleation of the prostate (HoLEP), Holmium laser resection of the prostate (HoLRP), photoselective vaporization of the prostate (PVP), Thulium laser, open prostatectomy (OP), and laparoscopic simple prostatectomy (LSP). In direct comparisons, all surgical treatments did not decrease postoperative International Index of Erectile Function (IIEF)-5 score except PVP. Moreover, patients who underwent HoLEP, PKEP, Thulium laser, and TURP had their postoperative EF significantly increased. Network analysis including direct and indirect comparisons ranked LSP at the highest position on the variation of postoperative IIEF-5 score, followed by PKRP, HoLEP, TURP, Thulium laser, PKEP, PVP, HoLRP, and OP. In subgroup analysis, only PVP was found lower postoperative EF in the short term and decreased baseline group, whereas TURP increased postoperative IIEF-5 score only for patients with normal baseline EF. However, HoLEP and PKEP showed pro-erectile effect even for patients with decreased baseline EF and short-term follow-up. Our novel data demonstrating surgical treatments for LUTS/BPH showed no negative impact on postoperative EF except PVP. Moreover, HoLEP and PKEP were found pro-erectile effect for all subgroups. New technologies, such as LSP, PKRP, and Thulium laser, were ranked at top positions in the network analysis, although they had no pro-erectile effect in direct comparison due to limited original studies or poor baseline EF. Therefore, further studies and longer follow-up are required to substantiate our findings.

Review
Open retropubic radical prostatectomy (ORP) remains the "gold standard" for surgical treatment of clinically localized prostate cancer (PCa). Robot-assisted radical prostatectomy (RARP) is a robotic surgery used worldwide. The aim of this study is to collect the data available in the literature on RARP and ORP, and further evaluate the overall safety and efficacy of RARP vs. ORP for the treatment of clinically localized PCa. A literature search was performed using electronic databases between January 2009 and October 2013. Clinical data such as operation duration, transfusion rate, positive surgical margins (PSM), nerve sparing, 3- and 12-month urinary continence, and potency were pooled to carry out meta-analysis. Six studies were enrolled for this meta-analysis. The operation duration of RARP group was longer than that of ORP group (weighted mean difference = 64.84). There was no statistically significant difference in the transfusion rate, PSM rate, and between RARP and ORP (transfusion rate, OR = 0.30; PSM rate, OR = 0.94). No significant difference was seen in 3- and 12-month urinary continence recovery (3 months, OR = 1.32; 12 months, OR = 1.30). There was a statistically significant difference in potency between the 3- and 12-month groups (3 months, OR = 2.80; 12 months, OR = 1.70). RARP is a safe and feasible surgical technique for the treatment of clinically localized PCa owing to the advantages of fewer perioperative complications and quicker patency recovery.

Review
OBJECTIVE
To compare and evaluate the safety and efficacy of holmium laser enucleation of the prostate (HoLEP) and simple prostatectomy for large prostate burdens, as discussion and debate continue about the optimal surgical intervention for this common pathology.
MATERIALS AND METHODS
A systematic search was conducted for studies comparing HoLEP with simple prostatectomy [open (OP), robot-assisted, laparoscopic] using a sensitive strategy and in accordance with Cochrane collaboration guidelines. Primary parameters of interest were objective measurements including maximum urinary flow rate (Q max) and post-void residual urine volume (PVR), and subjective outcomes including International Prostate Symptom Score (IPSS) and quality of life (QoL). Secondary outcomes of interest included volume of tissue retrieved, catheterisation time, hospital stay, blood loss and serum sodium decrease. Data on baseline characteristics and complications were also collected. Where possible, comparable data were combined and meta-analysis was conducted.
RESULTS
In all, 310 articles were identified and after screening abstracts (114) and full manuscripts (14), three randomised studies (263 patients) were included, which met our pre-defined inclusion criteria. All these compared HoLEP with OP. The mean transrectal ultrasonography (TRUS) volume was 113.9 mL in the HoLEP group and 119.4 mL in the OP group. There was no statistically significant difference in Q max, PVR, IPSS and QoL at 12 and 24 months between the two interventions. OP was associated with a significantly shorter operative time (P = 0.01) and greater tissue retrieved (P < 0.001). However, with HoLEP there was significantly less blood loss (P < 0.001), patients had a shorter hospital stay (P = 0.03), and were catheterised for significantly fewer hours (P = 0.01). There were no significant differences in the total number of complications recorded amongst HoLEP and OP (P = 0.80).
CONCLUSION
The results of the meta-analysis have shown that HoLEP and OP possess similar overall efficacy profiles for both objective and subjective disease status outcome measures. This review shows these improvements persist to at least the 24 month follow-up point. Further randomised studies are warranted to fully determine the optimal surgical intervention for large prostate burdens.

Review
BACKGROUND
Increase in the diagnosis of prostate cancer has increased the incidence of radical prostatectomy. However, the literature assessing pain therapy for this procedure has not been systematically evaluated. Thus, optimal pain therapy for patients undergoing radical prostatectomy remains controversial.
METHODS
Medline, Embase, and Cochrane Central Register of Controlled Trials were searched for studies assessing the effects of analgesic and anesthetic interventions on pain after radical prostatectomy. All searches were conducted in October 2012 and updated in June 2015.
RESULTS
Most treatments studied improved pain relief and/or reduced opioid requirements. However, there were significant differences in the study designs and the variables evaluated, precluding quantitative analysis and consensus recommendations.
CONCLUSIONS
This systematic review reveals that there is a lack of evidence to develop an optimal pain management protocol in patients undergoing radical prostatectomy. Most studies assessed unimodal analgesic approaches rather than a multimodal technique. There is a need for more procedure-specific studies comparing pain and analgesic requirements for open and minimally invasive surgical procedures. Finally, while we wait for appropriate procedure specific evidence from publication of adequate studies assessing optimal pain management after radical prostatectomy, we propose a basic analgesic guideline.

Review
INTRODUCTION
Benign prostatic hyperplasia (BPH) is arguably the most common benign disease of mankind. As men age, the prostate inexorably grows often causing troubling symptoms causing them to seek out care. While traditionally treated by transurethral resection or open surgical removal of the hypertrophied adenoma, today the urologist has numerous medical, surgical and minimally invasive techniques available. In this supplement The Canadian Journal of Urology provides a review of the various techniques and medications available today.
MATERIALS AND METHODS
As an introduction to the supplement, the aim of this article is to review the epidemiology and economy of BPH as well as its natural history and diagnosis. A systematic review of available literature was looking for articles on BPH and its epidemiology, economics, natural history and management using PubMed database.
RESULTS
The prevalence of this condition is increasing with the population aging and so does the economic burden. The exact etiology of this condition is unknown, but some risk factors have been identified. The diagnostic and treatment of this very common disease should rely on a strong collaboration between primary care physician and urologist.
CONCLUSION
There are multiple options in treating BPH including medical, surgical and newer minimally invasive options. The challenge with having a variety of options is to review them with the patient and help the patient select the best treatment option for their condition.

Review
BACKGROUND
The use of radical prostatectomy for the treatment of prostate cancer has been increasing during the last decade partially due to the widespread adoption of the robotic-assisted laparoscopic technique. Although no prospective, randomized controlled trials have compared open radical prostatectomy (ORP) with robotic-assisted laparoscopic radical prostatectomy (RALRP), numerous comparative studies have been retrospectively conducted.
METHODS
A systematic review of the literature was performed to clarify the role and advancement of RALRP. Studies comparing ORP with RALRP that measured outcomes of cancer control, urinary and sexual function, and complications were included. A nonsystematic review was utilized to describe the advancements in the techniques used for RALRP.
RESULTS
RALRP is the procedure of choice when treating localized prostate cancer. This preference is due to the observed improvement in morbidity rates, as evidenced by decreased rates of blood loss and postoperative pain and similar oncological outcomes when compared with ORP. Robotic assistance during surgery is continually being modified and the techniques advanced, as evidenced by improved nerve sparing for preserving potency and reconstruction of the bladder neck to help in the early recovery of urinary continence.
CONCLUSIONS
Morbidity rates should continue to improve with the advancement of minimally invasive techniques for radical prostatectomy. The adoption of robotic assistance during surgery will continue as the applications of robotic-assisted surgery expand into other solid organ malignancies.

Review
BACKGROUND
Incontinence after prostatectomy for benign or malignant disease is a well-known and often a feared outcome. Although small degrees of incidental incontinence may go virtually unnoticed, larger degrees of incontinence can have a major impact on a man's quality of life.Conceptually, post-prostatectomy incontinence may be caused by sphincter malfunction or bladder dysfunction, or both. Most men with post-prostatectomy incontinence (60% to 100%) have stress urinary incontinence, which is involuntary urinary leakage on effort or exertion, or on sneezing or coughing. This may be due to intrinsic sphincter deficiency and may be treated with surgery for optimal management of incontinence. Detrusor dysfunction is more common after surgery for benign prostatic disease.
OBJECTIVES
To determine the effects of surgical treatment for urinary incontinence related to presumed sphincter deficiency after prostate surgery for:- men with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) - transurethral resection of prostate (TURP), photo vaporisation of the prostate, laser enucleation of the prostate or open prostatectomy - and- men with prostate cancer - radical prostatectomy (retropubic, perineal, laparoscopic, or robotic).
SEARCH METHODS
We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, and handsearching of journals and conference proceedings (searched 31 March 2014); MEDLINE (January 1966 to April 2014); EMBASE (January 1988 to April 2014); and LILACS (January 1982 to April 2014). We handsearched the reference lists of relevant articles and conference proceedings. We contacted investigators to locate studies.
SELECTION CRITERIA
Randomised or quasi-randomised trials that include surgical treatments of urinary incontinence after prostate surgery.
DATA COLLECTION AND ANALYSIS
Two authors independently screened the trials identified, appraised quality of papers, and extracted data.
MAIN RESULTS
Only one study with 45 participants met the inclusion criteria. Men were divided in two sub-groups (minimal or total incontinence) and each group was randomised to artificial urethral sphincter (AUS) implantation or Macroplastique injection. Follow-up ranged from six to 120 months. In the trial as a whole, the men treated with AUS were more likely to be dry (18/20, 82%) than those who had the injectable treatment (11/23, 46%) (odds ratio (OR) 5.67, 95% confidence interval (CI) 1.28 to 25.10). However, this effect was only statistically significant for the men with more severe ('total') incontinence (OR 8.89, 95% CI 1.40 to 56.57) and the CIs were wide. There were more severe complications in the group undergoing AUS, and the costs were higher. AUS implantation was complicated in 5/22 (23%) men: the implant had to be removed from one man because of infection and in one man due to the erosion of the cuff, in one man the pump was changed due to mechanical failure, in one man there was migration to the intraperitoneal region, and one man experienced scrotal erosion. In the injectable group, 3/23 (13%) men had a complication: one man treated with Macroplastique injection had to be catheterised because of urinary retention and two men developed urinary tract infections.
AUTHORS' CONCLUSIONS
The evidence available at present was of very low quality because we identified only one small randomised clinical trial. Although the result was favourable for the implantation of AUS in the group with severe incontinence, this result should be considered with caution due to the small sample size and uncertain methodological quality of the study found.

Meta-Analysis Review
Holmium laser enucleation versus transurethral resection in patients with benign prostate hyperplasia: an updated systematic review with meta-analysis and trial sequential analysis.
BACKGROUND
Holmium laser enucleation (HoLEP) in surgical treatment of benign prostate hyperplasia (BPH) potentially offers advantages over transurethral resection of the prostate (TURP).
METHODS
Published randomized controlled trials (RCTs) were identified from PubMed, EMBASE, Science Citation Index, and the Cochrane Library up to October 10, 2013 (updated on February 5, 2014). After methodological quality assessment and data extraction, meta-analysis was performed using STATA 12.0 and Trial Sequential Analysis (TSA) 0.9 software.
RESULTS
Fifteen studies including 8 RCTs involving 855 patients met the criteria. The results of meta-analysis showed that: a) efficacy indicators: there was no significant difference in quality of life between the two groups (P>0.05), but compared with the TURP group, Qmax was better at 3 months and 12 months, PVR was less at 6, 12 months, and IPSS was lower at 12 months in the HoLEP, b) safety indicators: compared with the TURP, HoLEP had less blood transfusion (RR 0.17, 95% CI 0.06 to 0.47), but there was no significant difference in early and late postoperative complications (P>0.05), and c) perioperative indicators: HoLEP was associated with longer operation time (WMD 14.19 min, 95% CI 6.30 to 22.08 min), shorter catheterization time (WMD -19.97 h, 95% CI -24.24 to -15.70 h) and hospital stay (WMD -25.25 h, 95% CI -29.81 to -20.68 h).
CONCLUSIONS
In conventional meta-analyses, there is no clinically relevant difference in early and late postoperative complications between the two techniques, but HoLEP is preferable due to advantage in the curative effect, less blood transfusion rate, shorter catheterization duration time and hospital stay. However, trial sequential analysis does not allow us to draw any solid conclusion in overall clinical benefit comparison between the two approaches. Further large, well-designed, multicentre/international RCTs with long-term data and the comparison between the two approaches remain open.
