Complete urethral duplication is a rare congenital genitourinary anomaly with various symptoms. Since anatomical place of urethra greatly varies between cases, surgical management of the patients is personalized according to the type of the duplication and requires a careful workup before planning for any intervention. In this case report, a 4-year-old boy with finding of complete proximal hypospadiac urethral duplication is presented with double-stream voiding. He was passing a normal stream of urine through the hypospadiac tract, while a thin stream came out from the normal meatal site. Examination revealed a hypoplastic orthotopic urethra with an accessory penoscrotal hypospadiac urethra. The patient was successfully managed with hydrodistension technique which was used to resolve the stricture of hypoplastic dorsal urethra followed by end-to-end anastomosis to penoscrotal hypospadias. This approach gives an insight that the technique could be possibly considered as a simple alternative to avoid proximal hypospadias repair which is comparatively a challenging surgical task.
完全性尿道重复是一种罕见的先天性泌尿生殖系统异常，有多种症状。由于不同病例中尿道的解剖位置差异很大，患者的手术治疗需根据重复类型个体化进行，且在计划任何干预措施之前都需要进行仔细的检查。在本病例报告中，一名4岁男孩被发现患有完全性近端尿道下裂型尿道重复，表现为双流排尿。他通过尿道下裂通道排出正常的尿流，而细尿流则从正常尿道口排出。检查发现原位尿道发育不全，伴有副阴茎阴囊型尿道下裂尿道。该患者通过水扩张技术成功治疗，该技术用于解决发育不全的背侧尿道狭窄，随后进行与阴茎阴囊型尿道下裂的端端吻合。这种方法表明，该技术可能被视为一种简单的替代方法，以避免相对具有挑战性的近端尿道下裂修复手术。
