Bladder Stone Formation on Intra-uterine Contraceptive Device Perforated into the Bladder / 대한비뇨기과학회지

ABSTRACT

Various intravesical foreign bodies have been extracted from the bladder. Their introduction into the bladder may be through self-insertion, iatrogenic insertion or migration from the adjacent organs. The means of extracting the foreign bodies differ according to the nature and characteristics of the foreign bodies and to minimize bladder and urethral injury. However, complete extraction should also be confirmed after the extraction procedure. Bladder stone formation in an intra-uterine contraceptive device that perforates into the bladder seldom occurs. We experienced a case of a bladder stone that formed in an intra-uterine contraceptive device, which had perforated into the bladder. The possibility of an intravesical foreign body should be considered in any patient with chronic unexplained lower urinary tract symptoms.
