The duplex ureter in Burnley, Pendle and Rossendale

Following the report of an unusually high number of patients presenting with duplex ureter in the Dorchester area, we reviewed the incidence of duplex ureter in the Burnley, Pendle and Rossendale district. Based on a review of intravenous urograms, the prevalence was found to be 3.7% (16 of 432). This confirmed the authors' clinical impression that the incidence was higher than previously quoted figures.
