Multiple Secondary Vesical Calculi in a Large Incarcerated Inguinoscrotal Bladder Hernia.

Inguinal herniation of the urinary bladder is rare. Although in most patients it is an incidental finding during hernia repair, some patients present with complications related to herniated bladder. A 65-year-old man presented with recurrent lower urinary tract infections and multiple episodes of lithuria. He was found to have an incarcerated right inguinal hernia with a large part of the urinary bladder inside the hernial sac. He did not have any features of bladder outlet obstruction. The herniated bladder had multiple small secondary vesical calculi that had probably formed in this hernial sac. He was managed by open surgical mesh hernioplasty followed by cystoscopic stone evacuation. Incarcerated bladder herniation, complicated by intravesical stone formation, is a rare clinical condition. Proper preoperative imaging with CT scan best confirms the diagnosis. Appropriate treatment includes reduction of the bladder, hernia repair, and endoscopic stone management.
