The fanciful metaphor “golf ball-on-tee” (Fig. 1) describes imaging findings that signify renal papillary necrosis [1, 2]. Once opacified with contrast material, the central calyceal cavity (the “golf ball”) appears to rest on the calyx (the “tee”). While this sign originally was described at excretory urography, the findings are now most often seen on CT (Fig. 2A, B) [3]. Other “classic” imaging patterns of papillary excavation seen in papillary necrosis include the “lobster claw” and “signet ring” appearance (Fig. 3).
WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.
Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
