Tumour size >3.0 cm was a significant predictor of CSS, RFS and OS after RNU for patients with UTUC. Further studies are warranted before tumour size is included in risk prediction tools.
In this work, we aim to further analyze the association of statins use with biochemical recurrence (BCR) of prostate cancer (PCa) and PCa-specific mortality after definitive therapy. A systematic literature search of PubMed, MEDLINE, and EMBASE through Jul 2015 was conducted. Pooled Hazard ratio (HR) estimates with corresponding 95% confidence intervals (CIs) were calculated using random-effects model. STATA version 10 (Stata corporation, college station, TX) was employed to conduct all statistical analyses. A total of 22 and 8 studies contributed to the biochemical recurrence analysis and PCa-specific mortality, respectively. 13 trials were included for BCR-free survival analysis. The combined result showed statins users had lowered 12% BCR risk of PCa compared with non-users (HR = 0.88, 95%CI: 0.765–0.998) (p < 0.05). The association was null among the men who underwent radical prostatectomy as primary therapy (HR = 0.96, 95%CI: 0.83–1.09), while the improved outcomes had be seen among patients who received radiation therapy (HR = 0.67, 95%CI: 0.48–0.86). After excluding the patients undergoing ADT, participants did not benefit from statins use (HR = 0.94, 95%CI: 0.77–1.11). Meanwhile, long-term statins using did not alter recurrence risk. A lower risk of prostate cancer-specific mortality was observed among statins users (HR = 0.68, 95%CI: 0.56–0.80). There was a plausible trend towards increasing the BCR-free survival rate among statins users.
This paper was aimed to compare the clinical effectiveness and safety of adult male circumcision using the Shang Ring™ (SR) with the no-flip technique compared with Dorsal Slit (DS) surgical method. A single-centered, prospective study was conducted at the West China Hospital, where patients were circumcised using the no-flip SR (n = 408) or the DS (n = 94) procedure. The adverse events (AEs) and satisfaction were recorded for both groups, and ring-removal time and percentage of delayed removals were recorded for the SR group. Finally, complete follow-up data were collected for 76.1% of patients (SR: n = 306; DS: n = 76). The average ring-removal time for the SR group was 17.62 ± 6.30 days. The operation time (P < 0.001), pain scores during the procedure (P < 0.001) and at 24 h postoperatively (P < 0.001), bleeding (P = 0.001), infection (P = 0.034), and satisfaction with penile appearance (P < 0.001) in the SR group were superior to those in the DS group. After two postoperative weeks, the percentage of patients with edema in the SR group (P = 0.029) was higher but no differences were found at 4 weeks (P = 0.185) between the two groups. In conclusions, the no-flip SR method was found to be superior to the DS method for its short operation time (<5 min), involving less pain, bleeding, infection, and resulting in a satisfactory appearance. However, the time for recovery from edema took longer, and patients may wear device for 2–3 weeks after the procedure.
BackgroundCurrent evidence regarding the efficacy of ethanol locks in preventing catheter-related bloodstream infection (CRBI) is inconclusive.MethodsElectronic databases, including PubMed, Web of Science, Embase, and the Cochrane Library (until April 2018),were systematically searched for relevant studies. Two reviewers independently screened the retrieved records and identified RCTs that met the inclusion criteria. Relevant data were extracted for pooled analyses using Review Manager 5.3 software. Subgroup analysis was performed according to the study quality, duration of the ethanol lock, disease type and CRBI definition. Eggs’ method was applied to detect publication bias. Sensitivity analysis was conducted to check the stability of the meta-analysis results.ResultsTen RCTs involving 2760 patients were included in the analysis. The overall pooled result indicated that ethanol locks significantly reduced the incidence of CRBI (RR 0.66, 95% CI 0.51–0.86). Subgroup analysis suggested that an ethanol lock significantly decreased the incidence of CRBI in patients with hematological diseases (RR 0.50, 95% CI 0.31–0.80). An ethanol lock significantly reduced the incidence of CRBI in a2-hour ethanol lock group (RR 0.49, 95% CI 0.33–0.73). The meta-analysis showed that an ethanol lock significantly reduced the incidence of CRBI according to analysis of high-(RR 0.66, 95% CI 0.47–0.94) or low-(RR 0.66, 95% CI 0.46–0.95) quality studies. Meta-analysis of studies with a strict CRBI definition showed that an ethanol lock can significantly prevent CRBI (RR 0.61, 95% CI 0.42–0.89). The results of sensitivity analysis suggested that the pooled result was stable. Meta-analysis of adverse events showed that an ethanol lock did not increase the incidence of thrombosis (RR 1.05, 95% CI 0.51–2.18) or mortality (RR 0.99, 95% CI 0.90–1.08) but did result in increased nausea (RR 1.54, 95% CI 1.01–2.35), dizziness (RR 4.21, 95% CI 2.40–7.39),elevated blushing rates (RR 3.27, 95% CI 2.05–5.22) and altered taste rates (RR 2.61, 95% CI 1.93–3.54).ConclusionsAn ethanol lock may play a role in the prevention of CRBI, especially in immunocompromised patients with hematological diseases.Electronic supplementary materialThe online version of this article (10.1186/s12871-018-0548-y) contains supplementary material, which is available to authorized users.
Background Penile cancer represents a rare pathology whose natural history of treatment is poorly understood. Objective To illustrate the dynamic survival profiles in surgically treated patients with squamous cell carcinoma of the penis (SCCP) using the conditional survival (CS) estimates. Materials and methods Patients with non‐metastatic SCCP were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Conditional 3‐yr overall survival (OS) rate and 3‐yr cancer‐specific survival (CSS) rate represented the primary outcomes of interest and were calculated using the Kaplan‐Meier method. The multivariable Cox regression model was employed to calculate proportional hazard ratios for the prediction of mortality. Results A total of 1887 SCCP patients who had undergone surgeries were identified. Given a 1‐, 2‐, 3‐, 4‐, and 5‐yr survivorship, the 3‐yr OS rates were, respectively, improved by + 9.8 (72.6%), +18.2 (78.1%), +23.4 (81.6%), +27.8 (84.5%), and + 26.6% (83.7%) from those calculated at baseline (time zero). As compared with the baseline calculations, patients who had survived 1, 2, 3, 4, or 5 yr after surgery could, respectively, harvest a + 7.8 (84.7%), +14.8 (90.2%), +19.5 (93.9%), +22.1 (96.0%), and + 22.4% (96.2%) improvement in 3‐yr CSS. Patients with the most aggressive disease at baseline ultimately benefited the most from event‐free survivorship. Multivariable Cox regression analyses showed that the impact of adverse pathological parameters (G2‐3, ≥ pT2, pN+) on OS and CSS mostly showed a decreasing trend over time and some could disappear after a minimum of 1‐yr survivorship. Discussion and conclusion The survival probability of SCCP patients increases with post‐operative survival. Patients with aggressive disease at baseline ultimately benefit the most from event‐free survivorship and may expect a better prognosis once they survive the critical few years after surgery. The recorded observations have crucial implications regarding patient counseling and follow‐up.
This paper was aimed to introduce and compare outcomes of a novel “Su-Wang (S-W) technique” for endoscopic treatment of adult hydrocele with conventional open hydrocelectomy with “Jaboulay’s (JA) procedure” regarding adverse events (AEs) and patient satisfaction. In the randomized controlled trial, adult males with primary hydroceles were prospectively assigned into S-W or JA group. We recorded perioperative data and postoperative AEs (incision length, recurrence, hematoma, wound infection and edema vanished time). Finally, a total of 42 adult patients underwent the S-W (n = 22) or JA (n = 20) procedure. Procedures were successfully completed for all 42 patients. No significant differences were found between the two groups regarding age, symptom duration, body mass index, and size of the hydrocele. The incision length was significantly shorter in the S-W group (1.00 ± 0.24 cm) than in the JA group (6.10 ± 1.46 cm). After 6 months’ follow-up, complete data of 90.5% (38/42) were obtained. Severe AEs did not occur in any patient. Recurrence, hematoma, wound infection, edema vanished time values, and satisfaction in the S-W group were superior to those in the JA group. All patients in the S-W group were satisfied with this novel procedure, particularly due to the minimally invasive incision. In conclusion, the novel “S-W technique” for hydrocelectomy provided satisfactory cosmetic results with a 1-cm scrotal incision only. With the near-complete excision of the parietal TV, it resulted in no recurrence, fewer AEs, and rapid postoperative rehabilitation in comparison to the traditional “JA procedure.” The endoscopic “S-W technique” may be a viable alternative for the surgical treatment of adult primary vaginal hydrocele.
Background Management of chronic idiopathic testicular pain may be difficult because of problems identifying the causes. We evaluated “AUTOKLAV”, a novel endourological nephrolithotomy device to diagnose and treat chronic idiopathic testicular pain. Methods We divided 103 patients to either scrotoscopy group (SG, n = 64) or open exploration group (OEG, n = 39) between September 2014 and March 2017 at Zhongnan Hospital. Perioperative information, like operating time, length of incision, and wound infections, was carefully recorded during in hospital. Follow-up data, like pain scores improvement, satisfaction with penis appearance, and adverse event, were collected at one month postoperatively. Results Finally, both the operating time and length of incision showed better performance for SG (43.6 ± 4.7 versus 51.5 ± 9.0 min; 0.7 ± 0.2 versus 4.1 ± 0.8 cm; both P <0.01). Though the pain improvement had no significant differences between the two groups (2.92 ± 0.99 and 2.14 ± 1.02, p>0.05), SG showed obvious advantages in incidence of wound infections and satisfaction with wound/scrotum appearance (0% versus 2.9%; 96.4% versus 85.3%, both P<0.05). Conclusions In conclusion, scrotoscopy using the novel AUTOKLAV device is feasible, has an acceptable complication rate, and can be effective and safe in men with idiopathic chronic testicular pain. Etiologically, secondary inflammatory changes caused by the complete or incomplete torsion of testicular or epididymis appendices or by the existence of stones in the tunica sac might be responsible for the pain.
