Treatment and outcome of fibroepithelial ureteral polyps: A systematic literature review.

ABSTRACT: Fibroepithelial polyps of the ureter are rare. Cases and small series are reported in the literature. The treatment of choice, outcome and appropriate follow-up regimen remain unclear.We conducted a systematic literature review of papers reporting fibroepithelial polyps of the ureter in adult patients. Articles published before 1980 were excluded.The search yielded 144 papers, of which 68 met the inclusion criteria. A reference scan from the included 68 yielded an additional 7 new articles. In total, our study included 75 articles (68 + 7). A total of 134 patients were described. Most patients had a single lesion (range: 1-10). The median length of the polyp was 4.0 cm (range: 0.4-17.0). The percentage of polyps resected endoscopically increased from 0% before 1985 to 67% after 2005. Two perioperative complications were reported in 72 procedures (2.8%): a deep venous thrombosis and a case of mesenteric lymphadenopathy. Both of these occurred after open surgery. Follow-up data were available for 57 patients. The median follow-up was 12 months (range: 1-180). Four patients (7.0%) developed recurrent complaints: 2 had urinary stones, 1 had a ureteral stricture and 1 had recurrence of the polyp. Three of these events followed endoscopic resection, and occurred within a year after the procedure.Endoscopic resection of fibroepithelial polyps seems to be safe and effective. It is minimally invasive and should be considered the gold standard where endoscopic expertise is available. We advise follow-up imaging by computed tomographic intravenous urography after 3 months and ultrasound after 1 year to detect late complications.

Project description:BackgroundThere is an increasing need to evaluate the production and impact of medical research produced by institutions. Many indicators exist, yet we do not have enough information about their relevance. The objective of this systematic review was (1) to identify all the indicators that could be used to measure the output and outcome of medical research carried out in institutions and (2) enlist their methodology, use, positive and negative points.MethodologyWe have searched 3 databases (Pubmed, Scopus, Web of Science) using the following keywords: [Research outcome* OR research output* OR bibliometric* OR scientometric* OR scientific production] AND [indicator* OR index* OR evaluation OR metrics]. We included articles presenting, discussing or evaluating indicators measuring the scientific production of an institution. The search was conducted by two independent authors using a standardised data extraction form. For each indicator we extracted its definition, calculation, its rationale and its positive and negative points. In order to reduce bias, data extraction and analysis was performed by two independent authors.FindingsWe included 76 articles. A total of 57 indicators were identified. We have classified those indicators into 6 categories: 9 indicators of research activity, 24 indicators of scientific production and impact, 5 indicators of collaboration, 7 indicators of industrial production, 4 indicators of dissemination, 8 indicators of health service impact. The most widely discussed and described is the h-index with 31 articles discussing it.DiscussionThe majority of indicators found are bibliometric indicators of scientific production and impact. Several indicators have been developed to improve the h-index. This indicator has also inspired the creation of two indicators to measure industrial production and collaboration. Several articles propose indicators measuring research impact without detailing a methodology for calculating them. Many bibliometric indicators identified have been created but have not been used or further discussed.

Project description:Background: There has been an exponential growth in the use of advanced technologies for three-dimensional (3D) virtual pre- and intra-operative planning of pelvic ring injury surgery but potential benefits remain unclear. The purpose of this study was to evaluate differences in intra- and post-operative results between 3D and conventional (2D) surgery. Methods: A systematic review was performed including published studies between 1 January 2010 and 22 May 2020 on all available 3D techniques in pelvic ring injury surgery. Studies were assessed for their methodological quality according to the Modified McMaster Critical Review form. Differences in operation time, blood loss, fluoroscopy time, screw malposition rate, fracture reduction and functional outcome between 3D-assisted and conventional (2D) pelvic injury treatment were evaluated and a best-evidence synthesis was performed. Results: Eighteen studies fulfilled the inclusion criteria, evaluating a total of 988 patients. Overall quality was moderate. Regarding intra-operative results of 3D-assisted versus conventional surgery: The weighted mean operation time per screw was 43 min versus 52 min; for overall operation time 126 min versus 141 min; blood loss 275 ± 197 mL versus 549 ± 404 mL; fluoroscopy time 74 s versus 125 s and fluoroscopy frequency 29 ± 4 versus 63 ± 3. In terms of post-operative outcomes of 3D-assisted versus conventional surgery: weighted mean screw malposition rate was 8% versus 18%; quality of fracture reduction measured by the total excellent/good rate by Matta was 86% versus 82% and Majeed excellent/good rate 88% versus 83%. Conclusion: The 3D-assisted surgery technologies seem to have a positive effect on operation time, blood loss, fluoroscopy dose, time and frequency as well as accuracy of screw placement. No improvement in clinical outcome in terms of fracture reduction and functional outcome has been established so far. Due to a wide range of methodological quality and heterogeneity between the included studies, results should be interpreted with caution.
