Abstract
- We report on 4 cases with a unilateral single ectopic ureter associated with ipsilateral dysplastic or hypoplastic kidney and the usefulness of preoperative magnetic resonance(MR) urography in revealing the ureteral course and detecting the insertion site of ectopic ureter. Among two cases of unilateral single ectopic ureter associated with dysplastic kidney, one drains into the seminal vesicle and the other drains into the urethra. The other two cases have unilateral single ectopic ureter associated with hypoplastic kidney that drain into the vagina. In all cases, MR urography shows the ureteral course and insertion site of ectopic ureter regardless of the renal function. We believe that MR urograhy is a useful technique for the diagnosis of unilateral single ectopic ureter associated with hypofunctioning kidney.
