Abstract:

Bladder calculies are stones or calcified materials found in the bladder. Foreign bodies that come into contact with the urine may cause bladder stones. Examples of foreign body include suture materials, clips, catheters, ureteral stents, urinary incontinence meshes or migration of an intrauterine device. A 63-year-old female patient was admitted to our urology clinic with dysuria, frequent urination and mixed type urinary incontinence for a year. The patient had a history of abdominal hysterectomy and Burch colposuspension two years ago. Computerized tomography of the patient revealed a bladder stone measuring 2.9 x 2.6 cm.The patient underwent cystolithotripsy with Holmium (Ho: YAG) laser. The bladder stone was found to be attached to the bladder wall by a polypropylene suture. The suture material was removed endoscopically. The patient has no complaints during the 2-year follow-up. . The presence of nonabsorbable suture material in the bladder is a well-known cause of urinary tract infection and stone formation, and defined complication of hysterectomy and colposuspension. . Information on the lithogenic properties of various suture materials is unfortunately limited to only in vitro and in vivo animal studies. In humans, experience with stone formation related to suture materials is limited to case reports. It has been observed that lithogenicity is related to the longevity of the suture material and in the studies carried out, it has been observed that the rate of calcification with non-absorbable sutures is higher. Treatment includes disintegration of the stone and removal of the foreign body causing the stone.
