Patients with duplex kidneys and a non functioning moiety undergo heminephrectomy as the preferred treatment of choice. The ureteral remnant is often ligated and left insitu fearing the risk of oinjury to the healthy ureter on the ipsilateral side. But such redundant ureters may lead to long term complications and require surgical excision for complete removal and may pose surgical challenges and post-operative complications

We present a case report of a 36 years old female who presented with fever and abdominal pain and a past history of recurrent abdominal pain and sepsis. Evaluation with MRI Pelvis showed a thick walled, tubular and tortuous cystic structure with diffusion restriction and wall enhancement, suggestive of remnant dilated and tortuous right upper pole moiety of ureter which is seen terminating as ureterocele/continuing as Gartner's cyst anterior to the vagina with secondary infection and abscess formation. She underwent robotic excision of the infeced redundant ureter along with the gartner’s cyst wall and marsupialization after cystoscopy and DJ stenting of the right normal ureter. Post operative period was uneventful and was discharged on POD-2.

 

Since most of the redundant ureters donot cause any complications it was left insitu in early days owing to the risk of bladder neck injury or injury to the normal ureter. But a small minority of such cases may lead to recurrent infections or abcesses of the remnant part. Due to the advancements in minimally invasive surgery, complete surgical excision of the remnant is advised to avoid such major complications.
