Hypoplastic dysplastic kidney with a vaginal ectopic ureter identified by technetium-99m-DMSA scintigraphy.
Ectopic insertion of a ureter draining a hypoplastic dysplastic kidney is a significant cause of urinary incontinence in girls. In this case, such a kidney was detected with 99mTc-DMSA scintigraphy but not by intravenous pyelography. Scintigraphy facilitated further delineation of the anatomy with CT prior to nephrectomy. Based on this case and a literature review, we suggest that 99mTc-DMSA scintigraphy be performed early when evaluating girls with urinary incontinence.
