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 and Safety of Acupuncture in Treating Stress Urinary Incontinence in Women from a Meta-Analysis of Four Randomized Controlled Trials.

PURPOSE: To verify the efficacy and safety of acupuncture in treating stress urinary incontinence (SUI) in women in a single treatment cycle lasting at least 6 weeks. METHODS: A preferred reporting items for systematic reviews and meta-analyses (PRISMA) summary was followed correctly. Through the use of EMBASE, Cochrane Library databases, and PubMed (until July 2021), we looked for randomized controlled trials. In addition, the included articles' original references were looked up as well. RESULTS: Totally, we analyzed four studies including 690 patients. Compared with the sham acupuncture group, this analysis verified that acupuncture was critically better result in decreasing mean urine leakage (p = 0.04), 1-hour pad test (p = 0.04), 72-hour incontinence episodes (p < 0.00001), International Consultation on Incontinence Questionnaire-Short Form scores (p = 0.0005) and improving patient self-evaluation (All p < 0.05). However, two groups had no statistical significance in improving pelvic floor muscle strength. In the matter of safety, mainly adverse events, especially with respect to pain, both groups showed no statistical difference. CONCLUSIONS: Acupuncture is more beneficial to patients with stress urinary incontinence in women with no critical difference in the incidence of advent events than sham acupuncture.

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.

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.

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.

Comparison of Serenoa repens With Tamsulosin in the Treatment of Benign Prostatic Hyperplasia: A Systematic Review and Meta-Analysis.

Studies reported that Serenoa repens was effective in relieving lower urinary tract symptoms (LUTS). This article carried out a systematic review and meta-analysis to compare Serenoa repens with tamsulosin in the treatment of benign prostatic hyperplasia (BPH) after at least 6-month treatment cycle. Four studies involving 1,080 patients (543 in the Serenoa repens group and 537 in the tamsulosin group) were included in the meta-analysis. The results were as follows: compared with tamsulosin, Serenoa repens had a same effect in treating BPH in terms of International Prostate Symptom Score (IPSS) (mean difference [MD] 0.63, 95% confidence interval [CI] [-0.33, 1.59], p = 0.20), quality of life (QoL) (MD 1.51, 95% CI [-1.51, 4.52], p = 0.33), maximum flow rate (Qmax) (MD 0.27, 95% CI [-0.15, 0.68], p = 0.21), postvoid residual volume (PVR) (MD -4.23, 95% CI [-22.97, 14.44], p = 0.65), prostate-specific antigen (PSA) (MD 0.46, 95% CI [-0.06, 0.97], p = 0.08) with the exception of prostate volume (PV) (MD -0.29, 95% CI [-0.41, -0.17], p < 0.00001). For side effects, Serenoa repens was well tolerated compared with tamsulosin especially in ejaculation disorders (odds ratio [OR] = 12.56, 95% CI [3.83, 41.18], p < 0.0001) and decreased libido (OR = 5.40; 95% CI [1.17, 24.87]; p = 0.03). This study indicated that Serenoa repens had the same effect in treating BPH compared with tamsulosin in terms of IPSS, QoL, and PVR after at least 6-month treatment cycle, however, the latter had a greater improvement in PV compared with the former. And Serenoa repens did not increase the risk of adverse events especially with respect to ejaculation disorders and libido decrease.

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.
