A geographical focus of duplex ureter.
Following the observation of an unusually high number of patients presenting with duplex ureter in Dorchester, a prospective study of 1930 autopsies was carried out in nine centres throughout the Wessex region. The prevalence of duplex ureter in Dorchester was 2.5% (5 of 200 autopsies) but did not exceed 0.6% elsewhere. The finding was confirmed by study of intravenous urograms in south-west Dorset carried out between 1982 and 1983, which showed a 6.0% prevalence of urinary tract duplication in radiographs from Dorchester.
