Rare Entity of Proximal Ureteral Diverticulum Managed by Robotic Resection and Ureteroureteral Anastomosis

Ureteral Diverticulum in 65-Year-Old Female

“…Left-sided proximal hydroureteronephrosis was found on CT and a diverticulum was revealed on retrograde ureterography. This patient underwent robot-assisted diverticulectomy and ureteral anastomosis [1]. This case report highlights the importance of contrast-enhanced CT with delayed images (CT urogram) in certain cases of complicated recurrent UTIs as renal ultrasound and/or non-contrast CT scans can miss certain rare or unusual pathologies.…”

“…On delayed images, a higher rate of contrast accumulation in the cavity of the UD can be observed and the UD opacification remains after the contrast is discharged from the upper urinary tract. The treatment of UD varies depending upon the clinical presentation [ 1 ]. Conservative management is preferred in the case of most asymptomatic UDs.…”

“…UD treatment should be focused on relieving ureteral obstruction caused by the diverticulum in order to preserve renal function and ensure ureteral patency [ 1 , 9 ]. The surgical methods that have been used in the management of ureteral diverticula include nephrectomy with partial ureterectomy, laparoscopic excision, robotic resection with ureterourethral anastomosis, and suture plication [ 10 ].…”

“…UD has been shown to occur in one of three varieties: congenital, acquired, and abortive. When the UD is a true diverticulum comprising all ureteral layers, it is termed congenital [ 1 ]. Acquired diverticula are the result of distal obstruction causing herniation of the mucosa.…”
