We evaluate whether bladder dysfunction is common in patients with ectopic ureterocele and, if so, whether it is an integral part of the ectopic ureterocele complex or a result of surgery.
From 1986 to 1995, 34 patients with a mean age of 10 months were treated for large or medium ectopic ureteroceles at our institution and 32 participated in postoperative followup. Bladder function was investigated by a careful history and repeat uroflowmetry, and residual urine estimation was assessed by ultrasound and cystometry.
Of the 32 patients 19 had infrequent voiding and 3 had incontinence. Cystometric bladder capacity was increased to greater than 150% of the normal value for age in 15 of 27 patients (55%). Uroflowmetry revealed greater than 5 ml. residual urine in 15 patients (56%). Postoperatively no radiological signs of bladder neck obstruction were found. Increased bladder capacity and residual urine did not correlate with ureterocele size or location, or surgical procedure. There was no progression of bladder dysfunction with age.
Children with ectopic ureterocele are at high risk for a high capacity bladder with incomplete emptying. This bladder dysfunction associated with ectopic ureterocele does not seem to be the result of surgery but an integral part of the disorder.
我们评估膀胱功能障碍在异位输尿管囊肿患者中是否常见，若常见，它是异位输尿管囊肿综合征的一个固有组成部分还是手术的结果。
1986年至1995年，我们机构对34例平均年龄10个月的大或中等大小异位输尿管囊肿患者进行了治疗，32例参与了术后随访。通过详细病史和重复尿流率测定来研究膀胱功能，通过超声和膀胱测压评估残余尿量。
32例患者中，19例排尿次数少，3例有尿失禁。27例患者中有15例（55%）膀胱测压容量增加至大于同年龄正常价值的150%。尿流率测定显示15例患者（56%）残余尿量大于5ml。术后未发现膀胱颈梗阻的放射学征象。膀胱容量增加和残余尿量与输尿管囊肿大小、位置或手术方式无关。膀胱功能障碍未随年龄进展。
异位输尿管囊肿患儿发生膀胱容量大且排空不完全的风险很高。这种与异位输尿管囊肿相关的膀胱功能障碍似乎不是手术的结果，而是该疾病的一个固有组成部分。
