Summary
A study found a higher prevalence of duplex ureter in Dorchester autopsies (2.5%) compared to other Wessex region centers (≤0.6%). This urinary tract anomaly was further confirmed by radiographic studies in the area.
Area of Science:
- Urology
- Medical Imaging
- Epidemiology
Background:
- An unusual cluster of patients with duplex ureter was observed in Dorchester.
- Duplex ureter is a congenital anomaly of the urinary tract.
Purpose of the Study:
- To investigate the prevalence of duplex ureter in the Wessex region.
- To determine if the observed high prevalence in Dorchester was statistically significant.
Main Methods:
- A prospective autopsy study involving 1930 cases across nine centers in the Wessex region.
- Analysis of intravenous urograms from south-west Dorset conducted between 1982 and 1983.
Main Results:
- The prevalence of duplex ureter in Dorchester autopsies was 2.5%, significantly higher than the 0.6% or less found in other centers.
- Radiographic studies confirmed a 6.0% prevalence of urinary tract duplication in Dorchester during 1982-1983.
Conclusions:
- The Dorchester area exhibited a notably higher prevalence of duplex ureter than expected.
- Further epidemiological investigation into the causes of this localized increase in urinary tract duplication is warranted.
