Jackstone Caliciel Complicating a Kidney Cyst: Clinical Case and Literature Review

Abstract

The jackstone is a rare type of urinary stone, recognized for its distinctive shape. While historically described in veterinary pathology, it has also been found in humans, most commonly in the bladder and typically associated with urinary stasis. However, its occurrence in the renal calyx is extremely rare. We report a case of a jackstone located in the renal calyx, secondary to a large Bosniak 1 renal cyst. The simultaneous presence of the calyceal stone and renal cyst prompted us to opt for open surgery, allowing for comprehensive treatment of both conditions. The patient’s postoperative recovery was smooth, demonstrating that despite its invasiveness, open surgery remains a relevant option for managing complex stones, particularly in resource-limited settings.
