Randomized controlled trials in endourology: a quality assessment.

Area of Science:

• Urology
• Clinical Research Methodology

Background:

• The Journal of Endourology has published numerous studies over two decades.
• Assessing the quality of reporting in randomized clinical trials (RCTs) is crucial for evidence-based medicine.

Purpose of the Study:

• To analyze the quality of reporting for randomized clinical trials (RCTs) published in the Journal of Endourology between 1993 and 2011.
• To identify trends in RCT publication and quality over time.

Main Methods:

• A systematic review of RCTs published in the Journal of Endourology from 1993-2011.
• Quality assessment using the Jadad scale, van Tulder scale, and Cochrane Collaboration Risk of Bias Tool (CCRBT).
• Studies were categorized by publication term, origin, subject, setting, IRB approval, funding, and blinding.

Main Results:

• A significant increase in the number of published RCTs was observed over the review period (18 in 1993-1999, 43 in 2000-2005, 104 in 2006-2011).
• Despite the increase in RCTs, the overall quality of reporting, as assessed by Jadad, van Tulder, and CCRBT scales, did not significantly improve.
• However, there was a significant increase in high-quality RCTs employing blinding methodology and those with Institutional Review Board (IRB) approval over time.

Conclusions:

• While the volume of RCTs in endourology has grown, the quality of reporting remains suboptimal.
• Researchers need to improve the description of key RCT elements, including randomization, allocation concealment, IRB approval, and financial disclosures.
• Enhanced reporting practices are essential for strengthening the reliability and validity of endourological research.
