Calcified clumped neodymium magnetic spheres as an intravesical foreign body: case report and literature review.

Foreign bodies in the bladder can occur by self-insertion, and patients often hide the symptoms owing to embarrassment. The foreign bodies act as a nidus for calculus formation when not detected for a long time. Foreign bodies can declare symptoms such as frequency, dysuria, nocturia, hematuria, urethrorrhagia, obstruction, or retention. This case spotlights self-inserted intravesical neodymium magnetic spheres clumped and calcified due to delayed presentation which were removed by open cystotomy after a cystoscopic failure.
