Single unilateral ectopic bifid ureter with contralateral orthotopic quadrufid ureter--a rare combination

This is a report a case with a unilateral single ectopic ureter associated with ipsilateral incomplete duplication of upper third of the ureter, contralateral quadrufid ureter and L3 hemivertebra. These findings provide further evidence of a generalised mesenchymal or epithelial defect, which would explain a defective ureteral bud and metanephric development, besides associated anomalies.
