Pseudoureterocele: potential for misdiagnosis of an ectopic ureter as a ureterocele.

OBJECTIVE

To present several case reports of children with 'pseudoureteroceles'. Familiarization with this entity should help to avoid an error in diagnosis and possible improper therapy.

PATIENTS AND METHODS

Three girls with ectopic ureters entering mesonephric duct cysts are presented for review.

RESULTS

Misdiagnosis of the pseudoureterocele as an ectopic ureter was made in two children. The 'pseudoureterocele' may lie dormant for many years and often presents with acute urinary incontinence and/or onset of urinary tract infections. Resection of the dysplastic kidney and ipsilateral ureter, marsupialization of the cyst into the vagina, and closure of the vesical fistula is the preferred treatment.

CONCLUSION

An ectopic ureter draining into a Gartner's duct cyst can be confused with an ectopic ureterocele. Correct diagnosis is vital to ensure proper treatment.
