The efficacy of platelet rich plasma in the treatment of erectile dysfunction: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Erectile dysfunction (ED) is a common issue among males, and the use of platelet-rich plasma (PRP) therapy for treating ED has gained increasing attention, but there is still no conclusive evidence regarding its efficacy. AIM: To evaluate the efficacy of PRP therapy for ED. METHODS: We systematically searched PubMed, Embase, Cochrane Library, and Web of Science databases up to November 2023 to identify randomized controlled trials (RCTs) on PRP therapy for ED. We used Review Manager version 5.4 for data analysis and management. RESULT: After applying inclusion and exclusion criteria for screening, a total of 4 studies involving 413 patients were finally included in our meta-analysis. According to our analysis, the PRP group showed significant advantages over the placebo group in terms of MCID at the first month (p = 0.03) and sixth months (p = 0.008), while there was no significant difference between the two groups at the third month (p = 0.19). Additionally, in terms of IIEF, PRP showed significantly better efficacy than placebo at the first, third, and sixth months (p < 0.00001). CONCLUSIONS: PRP shows more effectiveness in treating ED compared to placebo, offering hope as a potential alternative treatment for ED.

The pooled analysis evaluates the therapeutic efficacy of desmopressin combined with anticholinergic drugs in the treatment of pediatric nocturnal enuresis.

OBJECTIVE: This pooled analysis aims to demonstrate the clinical efficacy and safety of combined desmopressin and anticholinergic therapy in the treatment of pediatric nocturnal enuresis (NE). METHODS: A systematic search was conducted through PubMed, MEDLINE, EMBASE, ResearchGate, and Cochrane Library to identify all randomized controlled trials (RCTs) comparing monotherapy with desmopressin versus combined therapy with desmopressin and anticholinergic agents for the treatment of NE. Data analysis was performed using RevMan version 5.4.1. RESULTS: This study included 8 RCTs involving a total of 659 patients. The frequencies of complete response (CR), partial response (PR), and nonresponse (NR) were computed for both short-term treatment (1 month) and long-term treatment (3 months). Additionally, alterations in the mean number of NE episodes, adverse events, and relapse were assessed. Our analysis indicates that, in comparison to the monotherapy group, the combination therapy group plays a pivotal role in augmenting the CR odds and diminishing the NR ratios in both short-term and long-term treatments (1 month CR ratio [risk ratio (RR): 1.84; 95% confidence interval (CI): 1.22-2.76; p = 0.003, I2 = 72%]; 3 months CR ratio [RR: 1.48; 95% CI: 1.25-1.76; p < 0.00001, I2 = 0%]; 1 month NR ratio [RR: 0.67; 95% CI: 0.55-0.82; p = 0.0001, I2 = 0%]; 3 months CR ratio [RR: 0.37; 95% CI: 0.19-0.73; p = 0.004, I2 = 0%]). Furthermore, in both short-term and long-term treatment, the combined therapy group exhibits a greater magnitude of change in the average number of NE episodes compared to patients receiving monotherapy (1 month, mean difference [MD] = -2.97; 95% CI: -4.23 to -1.71, p < 0.0001; 3 months, MD = -4.30; 95% CI: -7.18 to -1.43, p = 0.003). Moreover, the combination therapy group exhibits a significant reduction in the recurrence rate (RR: 0.36; 95% CI: 0.15-0.86; p = 0.02). There is no significant difference in the incidence of adverse events between the two groups (RR: 1.16; 95% CI: 0.58-2.31; p = 0.67). CONCLUSION: Combining desmopressin with anticholinergic medications is more effective for NE than desmopressin alone, with lower recurrence and minimal adverse effects.

Updated recommendations on the therapeutic role of extracorporeal shock wave therapy for peyronie's disease: systematic review and meta-analysis.

BACKGROUND: The therapeutic role of extracorporeal shockwave therapy (ESWT) for Peyronie's disease (PD) has been controversial in a long term. We aimed to further evaluate the therapeutic effect of ESWT for PD on the basis of available high-quality studies. METHODS: The PubMed, CENTRAL and Embase databases were searched for articles published from January 1st, 2000 to December 31, 2022. Only randomized controlled trials (RCTs) using ESWT to treat PD were included. Meta-analysis and forest plots were carried out using Review Manager 5.4.1 software, and outcomes were reviewed by 2 authors independently. Using the Risk of Bias assessment form (ROB-2) by Cochrane Collaboration for quality assessment. PRISMA 2020 guidelines were used in this article to achieve the quantitative and qualitative synthesis of data. RESULTS: A total of four RCTs were included. 151 patients in the ESWT group and 150 patients in the control group. The meta-analysis results showed that ESWT could significantly reduce plaque size (OR 2.59, 95%CI 1.15 to 5.85, P = 0.02) and relieve pain (MD -1.55, 95%CI -2.46 to -0.64, P = 0.0008); but it has no significant effect on reducing the penile curvature (OR 1.93, 95%CI 0.87-4.26, P = 0.11) and improving sexual function (MD 2.6, 95%CI -1.63 to 6.83, P = 0.23), there is also no significant difference in complication rates between groups (OR 2.94, 95%CI 0.66 to 13.03, P = 0.16). The risk of bias of results is low. The limitations of this study are that the number of included studies is too small, some experimental outcomes are missing, and the expression of outcomes is not unified. CONCLUSIONS: For PD, ESWT can be considered as a safe short-term treatment, which can reduce plaque size and relieve pain, but cannot improve penile curvature and sexual function. Its long-term efficacy remains to be discussed. REGISTRATION NUMBER: PROSPERO (ID: CRD42023436744).

Robot-assisted radical cystectomy vs open radical cystectomy in patients with bladder cancer: a systematic review and meta-analysis of randomized controlled trials.

PURPOSE: Even though there isn't enough clinical evidence to demonstrate that robot-assisted radical cystectomy (RARC) is preferable to open radical cystectomy (ORC), RARC has become a widely used alternative. We performed the present study of RARC vs ORC with a focus on oncologic, pathological, perioperative, and complication-related outcomes and health-related quality of life (QOL). METHODS: We conducted a literature review up to August 2022. The search included PubMed, EMBASE and Cochrane controlled trials register databases. We classified the studies according to version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2). The data was assessed by Review Manager 5.4.0. RESULTS: 8 RCTs comparing 1024 patients were analyzed in our study. RARC was related to lower estimated blood loss (weighted mean difference (WMD): -328.2; 95% CI -463.49--192.92; p < 0.00001), lower blood transfusion rates (OR: 0.45; 95% CI 0.32 - 0.65; p < 0.0001) but longer operation time (WMD: 84.21; 95% CI 46.20 -121.72; p < 0.0001). And we found no significant difference in terms of positive surgical margins (P = 0.97), lymph node yield (P = 0.30) and length of stay (P = 0.99). Moreover, no significant difference was found between the two groups in terms of survival outcomes, pathological outcomes, postoperative complication outcomes and health-related QOL. CONCLUSION: Based on the present evidence, we demonstrated that RARC and ORC have similar cancer control results. RARC is related to less blood loss and lower transfusion rate. We found no difference in postoperative complications and health-related QOL between robotic and open approaches. RARC procedures could be used as an alternate treatment for bladder cancer patients. Additional RCTs with long-term follow-up are needed to validate this observation.

The efficacy of CO2 laser in the treatment of genitourinary syndrome of menopause: a systematic review and meta-analysis of randomized controlled trials.

CO2 laser has been proposed as a treatment strategy for genitourinary syndrome of menopause (GSM). In order to assess its efficacy for treating GSM, we conducted a systematic review and meta-analysis. To identify the current state of randomized controlled trials on CO2 laser therapy for GSM, a literature review was conducted. We systematically searched the following databases: PUBMED, EMBASE and the Cochrane Controlled Trials Register. In addition, a review of the references in the retrieved studies was carried out. Of 562 identified studies, 9 were eligible and were included in our analysis, involving 523 patients in total. Based on our analysis, CO2 laser has no statistical difference compared with estrogen in VHI (p = 0.87), FSFI total score (p = 0.19), FSFI-Arousal (p = 0.11), FSFI-Desire (p = 0.72), FSFI-Orgasm (p = 0.45) and FSFI-Satisfaction (p = 0.08). The meta-analysis also showed that CO2 laser significantly improved FSFI-Lubrication scores compared with estrogen therapy (p = 0.0004). Furthermore, compared with the sham group, CO2 laser group had statistically improved VHI scores (p = 0.003) and FSFI scores (p < 0.00001). CO2 laser therapy may be an effective alternative to estrogen therapy for GSM both in cases where estrogen is not applicable because of comorbidities and in cases in which women do not desire to take estrogen.

The network meta-analysis of "on-demand" and "daily" use of paroxetine in treating men with premature ejaculation from randomized controlled trials.

This network meta-analysis aimed to assess the efficacy and safety of "on-demand" and "daily" use of paroxetine for patients with premature ejaculation (PE). We searched PubMed, Embase and Cochrane Library from inception to October 2021 to collect randomized controlled trials, and 24 articles including 2, 308 patients were finally involved. The results indicated that paroxetine (daily or on-demand) was superior to placebo at increasing intravaginal ejaculatory latency time (IELT), and 20 mg paroxetine daily was significantly better than fluoxetine and tramadol in improving IELT. Besides, 20 mg paroxetine on-demand was less effective than 20 mg paroxetine on-demand plus phosphodiesterase-5 inhibitors (PDEI5) and tramadol monotherapy in increasing IELT. Tramadol monotherapy was more effective than paroxetine monotherapy in improving sexual satisfaction score. Although patients treated with paroxetine had more coitus/week than patients treated with placebo, it was less than patients treated with PDEI5. These findings were robust to sensitivity analyses. The common adverse events related with paroxetine were fatigue, yawning and abnormal sleep (10.96%), gastrointestinal upset (10.80%). The "on-demand" and "daily" use of paroxetine can significantly improve the clinical symptoms of patients with PE and were well tolerated. Combination therapy and tramadol monotherapy can also be used as alternative treatments.

Intraoperative and postoperative outcomes of thulium laser enucleation versus bipolar resection in the transurethral treatment of benign prostatic hyperplasia: a meta-analysis.

To compare the intraoperative and postoperative outcomes of thulium laser enucleation of the prostate (ThuLEP) vs bipolar transurethral resection of the prostate (B-TURP) in treating patients with benign prostatic hyperplasia (BPH). Clinical trials of ThuLEP and B-TURP in treating BPH were searched systematically by using PubMed, Cochrane Library databases, and EMBASE (until May 2021). The Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist was followed. The datum was calculated by Review Manager version 5.3.0. Four articles including 782 patients were studied in this analysis. The analysis discovered that there was no significant difference in operative time and percentage of tissue removed between ThuLEP and B-TURP. But the intraoperative irrigated volume and postoperative hemoglobin (Hb) decrease in the ThuLEP group was significantly less compared with the B-TURP group. The catheterization time and hospitalization duration in the B-TURP group was significantly longer than that in the ThuLEP group. Compared with those before treatment, the micturition indexes of the two groups improved significantly. But no significant difference was identified between ThuLEP and B-TURP for the variation of international prostate symptom score, quality of life, maximum flow rate, and post-void residual. By analyzing the postoperative complications, there were no significant discrepancies between ThuLEP and B-TURP in the incidence of blood transfusion, recatheterization, transient incontinence, bladder neck contracture, and urethral stricture. The micturition indexes and clinical symptoms were significantly improved after ThuLEP and B-TURP for patients with BPH. However, ThuLEP was more effective than B-TURP in terms of intraoperative irrigated volume, postoperative Hb decrease, catheterization time, and hospitalization duration.

A systematic review and meta-analysis of randomized controlled trials of "on-demand" use of tramadol vs "on-demand" use of paroxetine in the management of patients with premature ejaculation.

AIM: To evaluate the effect of "on-demand" use of tramadol vs "on-demand" use of paroxetine in the management of patients with premature ejaculation (PE). MATERIALS AND METHODS: A systematic search of PubMed, EMBASE, Cochrane Library databases and original references of the included articles was performed. PRISMA checklist was followed. The Cochrane Handbook was used to evaluate the quality of the included research. RESULTS: A total of seven articles including 663 patients were studied. The results indicated that patients who received on-demand therapy of tramadol or paroxetine showed significant improvement compared with those treated with placebo, as assessed by intravaginal ejaculatory latency time (IELT) (P < .00001 and P = .02, respectively) and sexual satisfaction score (P < .00001 and P < .00001, respectively). Furthermore, Patients who were treated with on-demand tramadol had a better effect than those treated with on-demand paroxetine in respect of IELT (P = .01) and sexual satisfaction score (P = .03). With regard to safety, the most common adverse event for the tramadol group was sleep disturbance and the most common adverse event for the paroxetine group was a headache. No serious adverse event was observed in both groups. CONCLUSIONS: Compared with placebo, on-demand therapy of tramadol or paroxetine showed a better improvements in IELT and sexual satisfaction scores. Besides, on-demand tramadol revealed a better effect than on-demand paroxetine for patients with PE, and patients in both groups showed good tolerance.

The role of N-acetyl-cysteine (NAC) orally daily on the sperm parameters and serum hormones in idiopathic infertile men: A systematic review and meta-analysis of randomised controlled trials.

The meta-analysis was performed to access the role of N-acetyl-cysteine (NAC) orally daily on the sperm parameters and serum hormones in idiopathic infertile men. Randomised controlled trials (RCTs) were retrieved using PubMed, EMBASE and Cochrane register databases. The references of included studies were also searched. Finally, three articles including 431 infertile men were analysed. The results indicated that the NAC group had a considerable improvement in sperm concentration (mean difference [MD], 3.80; p < .00001), ejaculate volume (MD, 0.69; p = .002), sperm motility (MD, 4.69; p < .0001) and normal morphology (MD, 1.68; p = .0002) compared with the placebo group. However, in terms of serum hormones, the NAC group did not show significant difference in increasing the serum levels of testosterone (MD, 1.35; p = .21), luteinising hormone (MD, 0.82; p = .40), follicle-stimulating hormone (MD, -7.48; p = .29) and prolactin (MD, -0.34; p = .32) compared with the placebo group. In conclusion, NAC orally daily produced a greater improvement in sperm concentration, ejaculate volume, sperm motility and normal morphology for idiopathic infertile men, whereas no significant influence in serum hormones, which required more high-quality RCTs with sufficient sample sizes and statistics to prove.

Analysis of pharmacological mechanisms of Yinyanghuo as treatment of erectile dysfunction with network pharmacology-based strategy.

Erectile dysfunction is considered an important health problem that impacts the quality of life of men. Yinyanghuo, also called Epimedium or Horny Goat Weed, is a frequently used Chinese traditional herbal medicine, commonly used in treating erectile dysfunction in China. A network pharmacology method was performed systematically, at a molecular level, to analyse the pharmacological mechanism of Yinyanghuo as erectile dysfunction therapy. The network pharmacology method used in this study primarily includes prescreening of the active compounds, prediction of targets, network analysis and gene enrichment analysis. This network analysis proved that 4 targets (AR, NR3C2, PDE5A and BMP2) could be the targets of Yinyanghuo therapy on erectile dysfunction. Besides, gene enrichment analysis predicted that Yinyanghuo might have a role in erectile dysfunction by regulating 10 molecular functions, 8 cellular components, 10 biological processes and 36 possible targets related to 10 signalling pathways. Our study demonstrated the molecular and pharmacological mechanisms of Yinyanghuo against erectile dysfunction with a holistic approach and demonstrated a powerful method for analysing pharmacological mechanisms and rational utilisation of Traditional Chinese Medicine clinically.

Outcomes and complications of naftopidil versus tamsulosin for elderly men with lower urinary tract symptoms secondary to benign prostatic hyperplasia: A systematic review and meta-analysis.

We conducted a systematic review and meta-analysis to assess the outcomes and complications of naftopidil in treating elderly men with lower urinary tract symptoms secondary to benign prostatic hyperplasia and compared them with those administered with tamsulosin. A literature review was performed to identify the available randomised controlled trials concerning the comparison between naftopidil and tamsulosin for men with LUTS/BPH. We searched the following databases: the Cochrane Library Database, PubMed, Embase and Web of Science. Eleven publications involving 1,114 men (557 in the naf group and 557 in the tam group) were pooled in our analysis. We found no significant differences in the total IPSS, IPSS storage score, IPSS voiding score, quality of life index, peak urinary flow rate, average flow rate and post-void residual volumes. We assessed cardiovascular and sexual adverse events, acute urinary retention, surgical intervention, withdrawals due to any reason and withdrawals due to adverse events. The incidence of adverse events was similar among patients in naf and tam groups. In conclusion, naftopidil shared comparable efficacy and similar incidence of adverse events with tamsulosin and appears to be a promising agent for and alternative to tam. However, more prospective trials with high quality and long-term treatment duration are needed to verify this observation.

Comparison of 532-nm GreenLight HPS laser with 980-nm diode laser vaporization of the prostate in treating patients with lower urinary tract symptom secondary to benign prostatic hyperplasia: a meta-analysis.

To evaluate the efficacy and safety of 532-nm GreenLight HPS laser (PVP) vs 980-nm diode laser vaporization of the prostate (DVP) in treating patients with lower urinary tract symptom (LUTS) secondary to benign prostatic hyperplasia (BPH). PubMed, Cochrane Library databases, EMBASE (until Jun 2020), and original references of the included articles were searched. PRISMA checklist was followed. A total of four articles including 521 patients were studied. There was no significant difference in total operating time and lasering time of the two laser surgeries; however, a higher amount of total applied laser energy was delivered with DVP (P < 0.00001). The catheterization time after surgery in the PVP group was significantly longer than that in the DVP group (P = 0.0008), whereas the hospitalization time was significantly shorter than that in the DVP group (P = 0.02). Compared with baseline, there were significant improvements in the voiding variables over the observation period after surgery in both groups. PVP had a significant improvement in total international prostate symptom score (IPSS) (P = 0.0002) and quality of life (QoL) index (P = 0.003) compared with DVP after ≥12 months of postoperative follow-up. For complications after surgery, PVP had a larger number in needing for electrocautery to control bleeding (P = 0.02). Besides, the application of DVP resulted in a higher incidence of bladder neck contracture (P = 0.0007), dysuria (≥1 month) (P = 0.002), transient incontinence (P = 0.003), postoperative recatheterization (P = 0.02), and reoperation (P < 0.0001). The voiding parameters and micturition symptoms of patients with BPH after two kinds of laser surgery were significantly improved. However, PVP was more beneficial than DVP in terms of total IPSS, QoL index, and hospitalization time. Moreover, PVP showed a lower incidence of postoperative adverse events, but a higher risk of postoperative bleeding. PROSPERO registration number: CRD42020203222.

Impact of differential ureteral stent diameters on clinical outcomes after ureteroscopy intracorporeal lithotripsy: A systematic review and meta-analysis.

In this meta-analysis we assessed whether the diameter of ureteral stents (4.7-5-Fr, 6-Fr) has an impact on the rate of occurrence of urinary tract symptoms and complications after successful URS and intracorporeal lithotripsy. A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A rigorous search for relevant studies published in MEDLINE, Embase, and the Cochrane Controlled Trials Register was conducted to find informative randomized controlled trials. The reference lists of relevant articles were also manually searched and reviewed. The protocol was prospectively registered at PROSPERO (CRD42020202164). All statistical evaluations were performed using RevMan software version 5.3.0. Seven articles comprising 547 patients were included in the meta-analysis. After placement of ureteral stents with different diameters for approximately 1 week, we found that ureteral stents with smaller diameters (4.7-5-Fr) were associated with significant improvements in the main domain scores on the Ureteral Stent Symptom Questionnaire, such as urinary symptoms (mean difference -4.47, 95% confidence interval -5.87 to -3.08; P < 0.00001) and body pain (mean difference -2.48, 95% confidence interval -4.37 to -0.59; P = 0.01), but poor outcomes in stent migration compared to ureteral stents with a 6-Fr diameter (odds ratio 3.00, 95% confidence interval 1.06-8.51; P = 0.04). However, there were no significant differences in Ureteral Stent Symptom Questionnaire scores with regard to work performance (mean difference -0.56, 95% confidence interval -2.52 to 1.40; P = 0.58), general health (mean difference -2.29, 95% confidence interval -4.95 to 0.37; P = 0.09), additional problems (mean difference -0.43, 95% confidence interval -1.02 to 0.15; P = 0.15), and complications such as fever (odds ratio 0.75, 95% confidence interval 0.24-2.39; P = 0.63). Ureteral stents with a diameter of 4.7-5-Fr have better outcomes than those with a diameter of 6-Fr, based on the Ureteral Stent Symptom Questionnaire pain and urinary tract symptoms scores. However, they are more prone to migration compared to those with a larger diameter.

The efficacy and safety of Vibegron in treating overactive bladder: A systematic review and pooled analysis of randomized controlled trials.

OBJECTIVE: Vibegron is a new kind of ß3-adrenergic receptor agonist. We performed a systematic review and pooled analysis to assess the efficacy, safety, and tolerability of Vibegron for treating overactive bladder (OAB). METHODS: MEDLINE, the Cochrane Controlled Trial Register and EMBASE were used to pick out randomized controlled trials (RCTs) of Vibegron in treating OAB. The reference lists of the retrieved articles were also studied. We used RevMan version 5.3.0. to analyze the data. RESULTS: Three high-quality RCTs involving a total of 2120 OAB patients were adopted in the systematic review and pooled analysis. The mean number of micturitions episodes/d (mean difference [MD] = -0.77; 95% confidence interval [CI] = -1.0 to -0.55; P < .00001); the mean number of urgency episodes/d (MD = -0.77; 95% CI = -1.03 to -0.52; P < .00001); mean number of urgency incontinence episodes/d (MD = -0.50; 95% CI = -0.64 to -0.35; P < .00001); mean number of incontinence episodes/d (MD = -0.45; 95% CI = -0.66 to -0.25; P < .0001); and mean volume voided/micturition (MD = 22.22; 95% CI = 17.36 to 27.07, P < .00001) showed that Vibegron was more efficacy in treating OAB than placebo. Dry mouth, drug-related treatment-emergent adverse event (TEAE), serious adverse event (SAE), and discontinuations due to adverse event (AE) suggested that Vibegron was well tolerated. CONCLUSIONS: Our systematic review and pooled analysis demonstrate that Vibegron 75 mg or 100 mg/d statistically significant improved OAB symptoms. The treatment was well-tolerated, with a favorable safety profile.

The efficacy of combined l-carnitine and l-acetyl carnitine in men with idiopathic oligoasthenoteratozoospermia: A systematic review and meta-analysis.

The purpose of our analysis is to identify the effect of l-carnitine (LC) and l-acetyl carnitine (LAC) on the semen parameters of men with idiopathic oligoasthenoteratozoospermia (iOAT). We performed a comprehensive search to ascertain all the trials about LC and LAC in the treatment of iOAT and compared the results, including percentage of total sperm motility, sperm concentration, percentage of forward sperm motility, semen volume, percentage of atypical forms, total motile spermatozoa, forward motile spermatozoa and the number of pregnancies between the two groups that treated with LC + LAC or placebo respectively. Seven randomised controlled trials (RCTs) involving 693 patients were included in our analysis. We found that patients who treated with LC and LAC had significantly increased the percentage of forward sperm motility (MD 6.98; 95% CI 1.06-12.90; p = .02), total motile spermatozoa (MD 16.45; 95% CI 8.10-24.79; p = .0001), forward motile spermatozoa (MD 13.01; 95% CI 11.08-14.94; p < .00001) and the number of pregnancies (OR 3.76; 95% CI 1.66-8.50; p = .002). However, no significant differences were found in other semen indicators between the two groups. LC and LAC can significantly increase part of the semen parameters. The combination therapy of LC and LAC is effective in the men with iOAT.

Long non-coding RNA CHRF promotes proliferation and mesenchymal transition (EMT) in prostate cancer cell line PC3 requiring up-regulating microRNA-10b.

Despite the advance of diagnosis and treatment for prostate cancer, the prognosis of metastatic prostate cancer is poor. We aimed to explore the functional role of long non-coding RNA cardiac hypertrophy-related factor (lncRNA CHRF) in prostate cancer cells (PC3) as well as the molecular mechanisms. LncRNA CHRF silence repressed cell number (%), down-regulated expression of cyclinD1, CDK4 and CDK6, and promoted apoptosis along with activation of the casapse-3 and caspase-9. LncRNA CHRF promoted mesenchymal transition (EMT), showing down-regulation of E-cadherin and up-regulation of N-cadherin, vimentin and ZEB1. Afterwards, we found miR-10b expression was positively correlated with lncRNA CHRF expression, and miR-10b inhibition could reverse the effects of lncRNA CHRF on PC3 and LNCaP cell proliferation and EMT. Finally, lncRNA CHRF was found to activate the GSK3ß/AKT and NF-κB pathways via up-regulation of miR-10b. LncRNA CHRF silence repressed proliferation and EMT while promoted apoptosis in PC3 cells via positive regulation of miR-10b. The GSK3ß/AKT and NF-κB pathways were activated by lncRNA CHRF, possibly through up-regulation of miR-10b.

Meta-analysis of efficacy and safety of continuous saline bladder irrigation compared with intravesical chemotherapy after transurethral resection of bladder tumors.

PURPOSE: We performed a meta-analysis to confirm the efficacy and safety of continuous saline bladder irrigation compared with intravesical chemotherapy after transurethral resection for the treatment of non-muscle invasive bladder cancer. METHODS: Randomized controlled trials of continuous saline bladder irrigation compared with intravesical chemotherapy were searched using MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. The data were evaluated and statistically analyzed using RevMan version 5.3.0. RESULTS: Four studies including 861 participants which compared continuous saline bladder irrigation with intravesical chemotherapy were considered. One-year recurrence-free survival [odds ratio (OR) = 0.76, 95% CI = 0.55-1.05, p = 0.09]; 2-year recurrence-free survival (OR = 0.94, 95% CI = 0.71-1.25, p = 0.68); the median period to first recurrence (OR = - 1.01, 95% CI = - 2.96 to 0.94, p = 0.31); the number of tumor progression (OR = 0.80, 95% CI = 0.54-1.17, p = 0.25); and the number of recurrence during follow-up (OR = 1.12, 95% CI = 0.84-1.50, p = 0.43) suggested that two methods of postoperative perfusion had no significant differences. In terms of safety, including macrohematuria, frequency of urination and bladder irritation symptoms, continuous saline bladder irrigation showed better tolerance than intravesical chemotherapy. CONCLUSION: Continuous saline bladder irrigation seems to provide a better balance between prevention of recurrence and local toxicities than intravesical chemotherapy after transurethral resection of bladder tumors.

The efficacy of electrical stimulation in treating children with nocturnal enuresis: A systematic review and meta-analysis.

AIM: We performed a systematic review and meta-analysis to evaluate the efficacy of electrical stimulation (ES) in treating children with nocturnal enuresis (NE). METHODS: Randomized controlled trials (RCTs) of the use of ES for the treatment of NE in children were searched using EMBASE, MEDLINE, and the Cochrane Controlled Trials Register. The references of related articles were also searched. The systematic review was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-analyses. RESULTS: Four RCTs involving 171 patients were studied. We found that there was statistically significant difference in the wet nights per week (mean difference [MD], -0.70; 95% confidence interval [CI], -0.89 to -0.51; P < .00001), the number of patients with clinical response (MD, 26.88; 95% CI, 11.16 to 64.74; P < .00001), and bladder capacity (MD, -0.70; 95% CI -0.89 to -0.51; P < .00001) in the ES group compared with the placebo group with the exception of maximum voided volume (MVV) (MD, 19.48; 95% CI, -9.18 to 48.14; P = .18). CONCLUSIONS: The study provides a significant improvement in statistics in the wet nights per week, the number of patients with clinical response and bladder capacity for children with NE compared with the placebo group with the exception of MVV.

Meta-analysis of the efficacy and safety of mirabegron and solifenacin monotherapy for overactive bladder.

AIM: We conducted a meta-analysis to evaluate the safety and efficacy of mirabegron (50 mg) and solifenacin (5 mg) monotherapy for overactive bladder (OAB) during a 12-week cycle. METHODS: Randomized controlled trials (RCTs) of mirabegron and solifenacin for OAB were searched systematically by using MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. The reference lists of retrieved studies were also perused. RESULTS: Five RCTs which compared solifenacin with mirabegron were studied. Mirabegron achieved the same effect as solifenacin in treating OAB. The mean number of incontinence episodes per 24 h (P = 0.20), mean number of micturitions per 24 h (P = 0.11), mean number of urgency episodes per 24 h (P = 0.23), and mean volume voided per micturition (P = 0.05) suggested that mirabegron and solifenacin had no significant differences in terms of OAB treatment. With regard to drug-related treatment-emergent adverse events (DR-TEAEs) and dry mouth, mirabegron showed better tolerance than solifenacin. Post-voiding residual volume showed a distinct difference in the two groups. Hypertension and tachycardia did not show a significant difference between the two groups, but the pulse rate did. CONCLUSION: The therapeutic effect of mirabegron is similar to that of solifenacin, and mirabegron does not increase the risk of adverse events (AEs).

Meta-analysis of the efficacy and safety of combination of tamsulosin plus dutasteride compared with tamsulosin monotherapy in treating benign prostatic hyperplasia.

BACKGROUND: We performed a meta-analysis to confirm the efficacy and safety of the combination of tamsulosin plus dutasteride compared with tamsulosin monotherapy in treating benign prostatic hyperplasia (BPH) during a treatment cycle of at least 1 year. METHODS: Randomized controlled trials were searched by using MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. Systematic review was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-analyses. The data was evaluated and statistically analyzed by using RevMan version 5.3.0. RESULTS: Five studies including 4348 patients were studied. The analysis found that the combination group was significantly greater effect in international prostate symptom score (mean difference [MD], - 1.43; 95% confidence interval [CI], - 2.20 to - 0.66; P = 0.0003), prostate volume (MD, - 10.13; 95% CI, - 12.38 to - 7.88; P < 0.00001), transitional zone volume (MD, - 3.18; 95% CI, - 3.57 to - 2.79; P<0.0001), maximum urine flow rate (MD, 1.05; 95% CI, 0.82 to 1.29; P < 0.00001), prostate specific antigen (MD, - 0.54; 95% CI, - 0.80 to - 0.29; P < 0.0001) and post-void residual volume (MD, - 3.85; 95% CI, - 4.95 to - 2.76; P < 0.00001) compared with the tamsulosin group. In terms of safety, including adverse events (odds ratio [OR], 2.06; 95% CI, 1.34 to 3.17; P = 0.001), erectile dysfunction (OR, 2.24; 95% CI, 1.73 to 2.92; P < 0.00001), ejaculation disorder (OR, 3.37; 95% CI, 1.97 to 5.79; P < 0.0001), retrograde ejaculation (OR, 2.30; 95% CI, 1.08 to 4.93; P = 0.03), decreased libido (OR, 2.25; 95% CI, 1.53 to 3.31; P < 0.0001) and loss of libido (OR, 3.38; 95% CI, 1.94 to 5.88; P<0.0001), the combination group showed poor tolerance than the tamsulosin group with the exception of dizziness (OR, 1.16; 95% CI, 0.75 to 1.80; P = 0.50). The combination group significantly reduced the risk of clinical progression than the tamsulosin group especially in incidence of BPH-related symptom progression (OR, 0.56; 95% CI, 0.46 to 0.67; P < 0.00001) and acute urinary retention (OR, 0.61; 95% CI, 0.38 to 0.98; P = 0.04). CONCLUSION: The combination of tamsulosin plus dutasteride provides a preferable therapeutic effect for BPH with a higher incidence of sexual side effects, but combination-therapy can markedly reduce risk of BPH-related symptom progression and acute urinary retention relative to tamsulosin monotherapy.
