Primary Giant Calculus in Female Urethral Diverticulum : Report of a Rare Case

Case Report Urethral diverticulum occurs in approximately 0.5-6% of women. Stone formation occurs in 1.5-10% of women with urethral diverticulum. Primary (native) urethral calculi occur rarely. In this case, 47 year-old woman suffering from recurrent urinary infections for the last 2 years referred to our clinic. Physical examination was normal except for a solid mass, measuring 3x3 cm in size, under the anterior vaginal wall mucosa, located at 3 cm to the external urethral orifice. Local excision of the mass was performed. Urethral calculus was removed after the incision was continued to the lumen of the diverticulum. After removing the calculi, the communication between the diverticulum and the urethral lumen was detected as the Foley catheter was seen through the vaginal incision.
