Most bladder stones develop in patients with bladder outlet obstruction. Intravesical stone formation after surgery outside the urinary bladder is rare.
A 54-year-old Taiwanese woman with lower urinary tract symptoms following a hysterectomy 14 years ago presented to our hospital. The intravesical calculus had developed from non-absorbable sutures and hung on the dome of the urinary bladder. The stone and residuum of the suture were retrieved by performing an endoscopic procedure.
The presence of an intravesical stone should be suspected in patients with a history of hysterectomy who have symptoms in the lower urinary tract. A hanging stone on the dome of the urinary bladder implies that suture materials migrate into the urinary bladder. The complication can be prevented by the routine use of absorbable material and double-checking with cystoscopy.
大多数膀胱结石发生于膀胱出口梗阻患者。膀胱外手术后膀胱内结石形成罕见。
一名54岁台湾女性，14年前子宫切除术后出现下尿路症状，前来我院就诊。膀胱内结石由不可吸收缝线形成，悬挂于膀胱顶部。通过内镜手术取出结石及缝线残留物。
有子宫切除术史且出现下尿路症状的患者应怀疑膀胱内有结石。膀胱顶部悬挂结石提示缝线材料移入膀胱。常规使用可吸收材料并通过膀胱镜检查进行复查可预防此并发症。
