Four Cases of Unilateral Single Ectopic Ureter with Ipsilateral Dysplastic or Hypoplastic Kidney in Children: the Diagnostic Value of MR Urography / 대한비뇨기과학회지

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.

A case of single vaginal ectopic ureter with preserved function of ectopic kidney / 대한비뇨기과학회지

We report a case of single vaginal ectopic ureter with ipsilateral small, malrotated ectopic right kidney in 5 year-old girl. She presented with persistent urinary leakage while normal voiding since birth. Excretory urogram, vaginogram and vaginoscopy confirmed the presence of vaginal ectopic ureter. The right terminal ureter was reimplantated into the bladder extravesically. Postoperatively, she has been well for 5 months with grade II-III/V vesicoureteral reflux on the right side.
