Double trouble: A unique case of TRUS biopsy induced left upper moiety infection of a duplicated ectopic ureter.

Duplex collecting systems are seen in 0.7% of the population and its association with an ectopic ureter (specifically in the ejaculatory duct) is even less common. We presented a 57 year-old male with an elevated PSA and suspicious findings on a multiparametric MRI (mpMRI) who underwent transrectal ultrasound (TRUS) guided biopsies. The procedure led to an infection of the upper moiety of the duplicated left collecting system with ectopic ureter draining into the ejaculatory duct. CT-scan was used for the diagnosis and an urgent surgical treatment was performed. To our knowledge, no such case has ever been reported.
