Twitter Mentions and Academic Citations in the Urologic Literature.

OBJECTIVE: To quantify the relationship between the number of Twitter mentions and the number of academic citations a urologic publication receives. MATERIALS AND METHODS: Two hundred and thirteen papers from 7 prominent urologic journals were examined 37 months after publication. Articles were evaluated with 2 citation based "bibliometrics" (Scopus, Google Scholar) and Twitter mentions were tracked using the Altmetric Bookmarklet. The number of article citations and Twitter mentions were compared using one-way Analysis of variance (ANOVA) and bivariate fit analysis. RESULTS: Seventy-three percent of articles had at least 1 Twitter mention. Forty-two percent of Twitter mentions occurred within the first week of the online publication date. Articles mentioned on Twitter had 2.0-fold more Scopus citations (P <.01), and 2.3-fold more Google Scholar citations (P <. 01) compared to articles with no Twitter mentions. Female urologic articles had the greatest number of Twitter mentions (5.7 mentions/article) while pediatric urology had the fewest mean number of Twitter mentions (0.8 mentions/article). A total of 8.9% of papers were tweeted by their authors. Author tweeted articles were associated with a 12.3 (2.0-fold) and 15.5 (1.8-fold) mean citation increase for Scopus and Google Scholar (P <. 01 and P = . 01) compared to articles not shared by their authors on Twitter. CONCLUSION: The majority of urologic publications are being shared on Twitter. The number of citations a urologic publication receives up to 3 years after release is positively associated with the number of mentions it has on Twitter. Twitter activity may be an early indicator of ultimate academic impact of an academic urologic paper.

Contemporary Practice Patterns in the Management of Acute Obstructing Ureteral Stones.

PURPOSE: To elucidate current practice patterns among Endourological Society members for acutely obstructing ureteral stones necessitating intervention. METHODS: A practice pattern survey was sent to members of the Endourological Society using Survey Monkey. The following question stem was given: "Patient presents to the ER with acute renal colic and intractable pain, no signs of infection, i.e. afebrile and no pyuria. Stone is obstructing, and causing intractable pain; thus observation or medical expulsive therapy is not appropriate." A follow-up stem was provided for specific scenarios: "Calculus measuring x mm at x location. What is your preferred management option?" The options given for immediate management included shockwave lithotripsy (SWL), ureteroscopy (URS), stent placement, or percutaneous management. RESULTS: Four hundred and sixteen complete responses of approximately 2000 were received. There was a significant difference in management choice based on stone location (P<0.001) and stone size (P<0.001). URS was the predominant modality used for urgent treatment of acute proximal ureteral stones from 5, 10, and 15 mm except for calculi of 20 mm, where the preference was for percutaneous management. Immediate URS was the preferred choice for all distal and midureteral stones, regardless of size. The use of stents vs percutaneous nephrostomy drainage was similar (18% vs 16%, respectively) for proximally obstructing calculi, while stent insertion was preferred over nephrostomy for mid and distal stones. CONCLUSIONS: Current practice patterns among endourologists indicate a strong preference for immediate URS management over stent placement or SWL for acutely obstructing ureteral calculi. Not surprisingly, 20-mm stones in the proximal ureter had percutaneous management.
