Objective: To describe the clinical features and treatment of a large stone associated with vesicovaginal fistula and analyze the contributing factors., Patients and Methods: 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., Results: 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., Conclusion: Vesicovaginal fistulas may be complicated by calculus. The contributing factors are foreign bodies and infection., (Copyright © 2012. Published by Elsevier Masson SAS.)

Objective: To analyze the epidemiological, anatomoclinical, surgical and evolutionary aspects of the urological complications of gynecological surgery., Material and Methods: It was about a retrospective survey, concerning 81 patients hospitalized in the department of urology of the university hospital, Brazzaville from 2000 to 2008 for urological complications of the gynecological surgery. The epidemiological, diagnostic, surgical and evolutionary parameters have been analyzed., Results: The urological complication of the gynecological surgery has been recovered in 3% of patients hospitalized in urology. The middle age was 37±14.52 years (17 and 74 years). The median was about 36 years. The middle delay of diagnosis was 15 days (0 and 350 days). The revealing clinical signs were: the oligoanuria (n=12), the urinary incontinence (n=57), the lumbar pain (n=9) and the cyclic hematuria (n=2). The surgical interventions in reason were: the Caesarean (n=50), the hysterectomy for fibroma (n=26), the myomectomy (n=3) and the hysterectomy for cancer (n=2). Anatomical lesion were 55 (67.9%) vesicovaginal fistulas, 12 (14.8%) ureteral ligatures, eight (10%) uretero-vaginal fistulas, three (3.7%) vesico-uterine fistulas, two (2.4%) wounds ureteral and one (1.2%) vaginal vesico-fistulas and uretero-vaginal fistulas. The treatment consisted in one termino-terminal ureterorraphia, 20 uretero-vesical reimplantation, 57 cures of vesico-vaginal fistulas and one nephrectomy. The recovery was obtained at 96% of the ureteral lesions and 90% of the vesico-vaginal fistulas., Conclusion: The lesions of the ureteral and the bladder were often met during the gynecological surgery. The treatment requires knowledge of the anatomy of pelvis., (Copyright © 2011 Elsevier Masson SAS. All rights reserved.)
