Background: H-index is an indicator of research productivity considered in faculty promotion. We examine trends in female authorship and effect of student authorship on H-index of principal investigators (PI).
Methods: Author gender, degree, designation as student, PI, or other, were recorded from Journal of Endourology from 2011 to 2020. PI Scopus H-index was recorded. PIs were classified into having student authors (SA) or not (nSA). Analysis conducted with IBM SPSS.
Results: Of 819 total articles, 26 % had SA. Articles with SAs increased from 22.2 % in 2011 to 31.1 % in 2020 (p for trend<0.01). There was an increasing trend in female authorship overall (R2 = 0.84). PIs with SA had a significantly higher mean H-index than those without, across all years (SA = 30.91, nSA = 27.45, p = 0.025).
Conclusions: Student authorship is increasing and positively benefits PI H-index. Female authorship is increasing overall within urology. Encouraging mentorship and student research can enhance and support female student interest in urology.
