[Stones associated with vesicovaginal fistulas]

To describe the clinical features and treatment of a large stone associated with vesicovaginal fistula and analyze the contributing factors.

From January 2000 to July 2011, seven patients were operated on for a large stone wedged in the vesicovaginal at the Urology Andrology department of the University Hospital of Brazzaville. For each case, the epidemiological, clinical, therapeutic aspects were analyzed.

Seven of 89 patients operated on for vesicovaginal in 10 years had a large stone. The age of patients ranged from 35 to 63 years with an average of 44 years. The age of the fistula ranged from 3 to 33 years. History were six caesarean sections and one obstructed labor. The urine culture performed in six patients had identified both Escherichia Coli, five times, and Proteus mirabilis, one time. The calculus was extracted five times by the bladder and two times vaginally. The dimensions of the calculi ranged from 3 to 7 cm of large diameter. The suture concomitant fistula was performed with four cures and three failures cured by a second course.

Vesicovaginal fistulas may be complicated by calculus. The contributing factors are foreign bodies and infection.
