Guide wires are frequently used in urology for upper and lower urinary tract procedures. Spontaneous knotting of guide wire is a rare complication and only a few cases have been reported in the literature until now. We report a case of spontaneous intravesical knotting of guide wire during per urethral catheterisation that led to retained Foley catheter. The balloon was punctured percutaneously under ultrasound guidance and the whole assembly was removed. Guide wire knot was found near the balloon. The cystoscopy showed normal urethra and bladder. The patient was recatheterised and is doing well.
导丝常用于泌尿外科的上尿路和下尿路手术。导丝自发打结是一种罕见的并发症，迄今为止文献中仅报道了少数病例。我们报告一例经尿道导尿时导丝在膀胱内自发打结导致Foley导尿管滞留的病例。在超声引导下经皮穿刺刺破球囊，并取出整个组件。发现导丝结位于球囊附近。膀胱镜检查显示尿道和膀胱正常。患者重新导尿，情况良好。
