The hernia of the bladder in the scrotum is a highly uncommon observation. From the clinical standpoint the usual manifestation is a two-stroke voiding. The recommended urological examinations to reach a diagnosis are ultrasound, endovenous urography, retrograde urethrocystography and cystoscopy. Management includes the de-obstruction of the lower urinary tract, if present, resection of associated peritoneum, resection or reduction of the vesical hernia and repairment of inguinal path. The case contributed corresponds to a vesical hernia in a 72-year-old patient, with no obstructive cause, that was treated surgically by resection of the herniated bladder, with good morphological and functional results.
