Signo Radiológico: "El lirio caído"

Abstract

Abstract: "The drooping lily" sign, also known as "wilting flower," corresponds to an imaginological alteration reported over 40 years ago. Initially described in excretory urography, it represents the appearance of the inferior ureteropelvic renal system with a duplicated collecting system, in which the renal pelvis is horizontal and calices are discreetly directed towards caudal. Despite the current limited use of excretory urography, the drooping lily sign remains valid and of diagnostic use in voiding cystourethrograms (VCUG) (also micturating cystourethrogram (MCUG)), computed tomography urography (CTU) and magnetic resonance urography (MRU).
