[Bladder stones as a complication of gynecologic surgery].

Two cases of urinary bladder-stone-formation after surgical treatment of a prolapsed uterus and an uterus-antefixation according to Kocher are reported. In both cases of synthetic, non absorbable suture was found. The patients suffered for several years from pollakisuria and dysuria although laboratory findings on the urine sediment were at least in an early stage not suspicious. The presence of urinary-bladder-stones was verified cystoscopically and the clinical symptomatology ceased promptly after removal of the concrements. Although formation of bladder-stone as described above seems to be quite rare, it should be prevented by the exclusive use of absorbable material in sutures in the region of the urinary bladder.
