title: Single-system ectopic ureter: a 15-year review.
abstract: Ectopic ureters present in childhood with symptoms related to an abnormal site or structure (refluxing, obstructed) of the ureteric orifice. The majority drain duplex kidneys. The diagnosis is relatively easy if the poles are functioning or hydronephrotic. Associated malformations are rarely seen and the results of surgery are gratifying. If an ectopic ureter drains a single kidney, it is called a single-system ectopic ureter (SSEU). We reviewed a 15-year experience (1980-1995) with 127 ectopic ureters from our hospital:11 SSEUs in ten consecutive children were managed during this period. Our data lead us to believe that SSEUs are a special subset of ectopic ureters. Diagnosis is often delayed because the ectopic ureter may be associated with a single small, dysplastic, poorly-functioning, non-visualised kidney and the child may be thought to have a contralateral normal "solitary kidney". Associated systemic malformations are common. Residual symptoms of wetting may persist in the early postoperative period. A high degree of suspicion must be maintained for this entity when a child presents with urinary symptoms of wetting or recurrent infection and a "solitary kidney". Early endoscopic examination of the genitourinary tract will clinch the diagnosis in the majority of cases. Residual symptoms of wetting in the postoperative period generally resolve with passage of time.
