Ectopic ureter with complete ureteric duplication: conservative surgical management.
To assess the outcome of conservative procedures, the authors reviewed their experience in the management of 31 ectopic ureters with complete ureteric duplication. Twenty-eight girls and three boys (aged 19 days to 10 years; mean, 30 months) were operated on between 1968 and 1994. Twenty-four of the children presented for evaluation of dribbling urinary incontinence and/or febrile urinary tract infections; seven presented after prenatal ultrasonographic diagnosis of hydronephrosis. The location of the ectopic orifice was identified in 25 children: bladder neck (6), posterior urethra (6), vagina (7), and vestibule (6). Upper pole nephroureterectomy was performed in 16 children who had nonfunctioning renal segments. Ureterovesical reimplantation was performed in 10 children who had functioning segments. In five borderline cases, temporary cutaneous ureterostomy was performed, followed by ureteropyelostomy (2), ureterovesical reimplantation (2), and upper pole nephrectomy (1). Histological examination of the polar nephrectomy specimens showed lesions of dysplasia in only four cases (24%). The follow-up period ranged from 6 months to 20 years (mean, 66 months). All children who presented with incontinence became continent after polar nephrectomy or conservative surgery. One child required surgical revision of the ureteropyelostomy anastomosis. Of the 12 children who had ureterovesical reimplantation, none needed further procedures. Ectopic ureters in duplex systems with functioning renal segments should be conserved.
