  • Title: Congenital bladder diverticula causing ureteral obstruction.
    Author: Livne PM, Gonzales ET.
    Journal: Urology; 1985 Mar; 25(3):273-6. PubMed ID: 3919483.
    Abstract:
    Two boys with congenital periureteral bladder diverticula without vesicoureteral reflux but with severe hydronephrosis and ureteral obstruction are described. No bladder outflow obstruction was present. Urinary tract infection was the presenting symptom in both boys, and this is the most common presenting symptom of bladder diverticula. Diverticulectomy, ureteral tailoring, and reimplantation were performed. Three different mechanisms are proposed for the association of bladder diverticula and ureteral obstruction: compression of the extravesical ureter against the detrusor by the full, tense diverticulum, fibrosis resulting from peridiverticulitis, or primary hypomuscularity of the ureterovesical junction and distal ureter.
