Vesicovaginal fistula with bladder and vaginal stone.

INTRODUCTION

In developing countries, Vesico-vaginal fistula (VVF) results following obstetric trauma or iatrogenic during hysterectomy. Large calculus associated with VVF is relatively rare, with the risk factor are presence of foreign body, urinary tract infection, and prolonged duration of disease. Most bladder stones can be found among patients who are bedridden, indwelling urethral catheter, bladder outlet obstruction, infection, and other similar characteristic. We report a case of VVF with bladder and vaginal stone in 37 years old woman and reviews the evaluation and treatment and highlights the role of the healthcare team in managing patients with this condition.

PRESENTATION OF CASE

A 37-year-old, P2A0, woman with a history of hysterectomy three years ago. Intermittent small amounts of watery vaginal discharge developed 1,5 years after the operation. A physical examination revealed mild tenderness over the suprapubic area and no evidence of uterine prolapse. Cystography computed tomography scan with contrast confirmed a fistula vesicovagina with a connection between posterosuperior wall of vesica urinaria and anterosuperior wall of vagina with vesicolithiasis, size 15 × 26 × 14 mm and two vaginal stone with size of 7 × 12 × 17 mm and 4 × 4 × 5 mm. Cystoscopy revealed a grayish stone identified in supratrigone with size of 30 × 12 mm.

DISCUSSION

A hanging intravesical stone on the dome of urinary bladder is scarce, possibly caused by any synthetic and non-absorbable suture material inside of the bladder were encrusted forming a bladder stone. Important risk factors known, which is specific in developing countries, are poor socioeconomic status, malnourishment, low literacy rate, early marriage and childbearing, and inadequate obstetrical care.

CONCLUSION

Although the incidence of VVF accompanied by hanging vaginal stone and a large bladder stone is scarce, reports of any case regarding this study can be beneficial to other studies. Due to its harmful effect, the usage of non-absorbable sutures material during surgery isn't suggested. Hence, the absorbable suture material usage with careful dissection is suggested for any gynecological or pelvic surgery.
