We report on 44 consecutive patients who underwent 1-stage hypospadias repair based on a urethral splent (silicone pleated stent). The severity of hypospadias ranged from subcoronal in 12 cases and distal in 23 to midshaft in 4 and penoscrotal in 5. In the first 15 patients of this series the splent was used with a suprapubic tube. All patients were able to void within the first 36 hours postoperatively. The next 29 patients underwent repairs without the use of a bladder catheter, including 15 who had outpatient procedures. None of the 44 patients has required subsequent catheterization or hospitalization. There have been 2 fistulas in this series. The urethral splent permits normal voiding through and drainage of the neourethra in a variety of hypospadias repairs. The splent expands and contracts with the degree of edema and permits catheterization should this be necessary. The advantages of hypospadias repair without bladder drainage, such as short hospital stay, total ambulation, and decreased potential for infection and bladder spasm, can be realized with the use of a urethral splent.
我们报告了44例连续接受基于尿道支撑物（硅胶褶皱支架）的一期尿道下裂修复术的患者。尿道下裂的严重程度从冠状沟下型12例、阴茎头型23例、阴茎体中段型4例到阴茎阴囊型5例不等。在该系列的前15例患者中，支撑物与耻骨上管一起使用。所有患者术后36小时内均能排尿。接下来的29例患者在未使用膀胱导管的情况下进行了修复，其中15例为门诊手术。44例患者中无一例需要后续导尿或住院治疗。该系列中有2例出现瘘管。尿道支撑物可使各种尿道下裂修复术中新尿道正常排尿和引流。支撑物会随着水肿程度扩张和收缩，如有必要还可进行导尿。使用尿道支撑物可实现无膀胱引流的尿道下裂修复术的优势，如住院时间短、完全可走动、感染和膀胱痉挛的可能性降低。
