Management of bladder stones associated with foreign bodies following incontinence and contraception surgery.

Aim of the study: To investigate success of endoscopic lithotripsy for bladder stone following stress urinary incontinance surgery and contraception surgery. Materials and methods: Charts of patients admitted in two centers between January 2006 and March 2013 were retrospectively reviewed and seven women were enrolled in our study. Patients demographic parameters including age, main complaint(s), previous surgery type, time to diagnosis were analyzed. Also operative time, hospitalisation lenght, perioperative and postoperative complication( s) were evaluated. Results: Five patients had undergone tension free vaginal tape procedure and one patient had undergone transobturator tape procedure. Median age was 62 (50-71) years. In one patient bladder stone formed around an intrauterine device. Dysuria (85%), hematuria (57%) and recurrent urinary tract infection (57%) were the main complaints. The median diagnosis time was 44.1 months. Abdominal ultrasonography and non contrast enhanced computer tomography were performed for five and two patients respectively and diagnosis was confirmed cystoscopically. Endoscopic lithotripsy using Holmium laser lithotripter or pneumatic lithotripter was used for all cases. The mean operation time was 41.2 minutes (20-70) and success was 100%. There was no intraoperative complication. Only one patient had fever higher than 38°C postoperatively and was treated by appropriate antibiotic. The median hospitalisation time was 1.57 day. Conclusion: In conclusion endoscopic lithotripsy is a safe and effective approach to manage bladder stone associated with mid-urethral synthetic slings and intrauterine devices. [ABSTRACT FROM AUTHOR]
