A 78-year-old man presented to the emergency department with 2 weeks of intermittent macroscopic hematuria, as well as recent bladder fullness, urgency, and suprapubic tenderness. His medical history included benign prostatic hypertrophy and recent placement of a Foley catheter in the context of urinary retention. Contrast-enhanced computed tomographic scans of the abdomen and pelvis demonstrated a 2-cm jackstone (image A and image B). The patient underwent continuous bladder irrigation and received appropriate antibiotics for an identified lower urinary tract infection. He subsequently underwent a transurethral resection of the prostate and transurethral cystolitholapaxy, by which the bladder stone was fragmented and removed successfully via irrigation.
