Abstract

The primary presentation of congenital megaureter in adults is
rare. Development of urolithiasis may lead to this unusual underlying
diagnosis. Urinary tract stones can form either within the
dilated ureteral segment or in a part of the upper urinary tract
proximal to the abnormal ureteral segment. We report two cases
of nephrolithiasis that occurred in adults found to have segmental
megaureter. The first case is that of a 58-year-old man who
presented with left lower quadrant pain. Computed tomography
scan revealed a 2-cm stone in the distal left ureter within an area
of isolated segmental distal ureteral dilation. The second case is
a 48-year-old man who developed recurrent renal urolithiasis
associated with isolated distal megaureter.
Although a rare condition in adults, congenital megaureter
may present when kidney stones develop as a result of the ureteral
abnormality. Typically, stones will develop within the dilated
segment of ureter. Atypically, stones may develop away from the
site of the underlying abnormality. Congenital megaureter is a
diagnosis that urologists and radiologists need to consider in the
setting of isolated distal ureteral dilation, as the diagnosis of adult
megaureter may require more involved surgical measures to prevent
recurrence of adverse symptoms.
