[Urethral duplication in pediatric age. A case report].

Urethral duplication is a rare congenital anomaly, resulting from a wide range of malformations of the urogenital sinus. Generally, the duplication develops on the sagittal plane; the accessory urethra may run dorsally or ventrally to the orthotopic one. The duplication is defined as epispadic in the first case, and hypospadic in the second. In the medical literature approximately 150 cases have been reported. Relatively more frequent among males, it is often associated with other malformations of the urogenital tract or other organs. The authors present a case of a 4 year old child with a complete epispadic duplication, that is, two external meatus, one of which the dorsal aspect of the glans, and the other orthotopic. Clinically, duplication and weakening of the stream, urinary incontinence and UTI were present. US examination documented the normality of the upper urinary tract and of the bladder. Retrograde urethrocystography showed a completely permeable urethral duplication, with two external meatus. The excision of the accessory urethra was carried out together with the reconstruction of the hypospadic meatus with an "overlap anastomosis". The post-operatory period was uneventful, and one year after surgery the patient is asymptomatic, with normal uroflowmetric readings and echographically documented complete bladder emptying. In the opinion of the authors, the treatment is indicated in symptomatic forms and the surgical options varies, depending on the type and grade of malformation, its clinical manifestations and the presence of associated anomalies. Antibiotic treatment is not effective and other treatments, such as diathermocoagulation or the injection of caustic substances into the accessory duct have been abandoned.
