Eccentric cases of genitourinary fistula—Our ten years of experience

Background:

A fistula is an unusual connection between two organs, vessels, or structures. Urological fistulas in developed countries are consequences of iatrogenic injury, and the more common cause of fistula development in these countries is related to labor sequence.

Case presentation:

More than 156 cases were treated in our hospitals during the last 10 years, and in this case report, we present only unusual fistula from two different urology departments. Different cases with a variety of fistula including huge stone formation following vesicouterine fistula, vesicosacral fistula and expelling urine from bedsore region of sacrum, fistula in the junction of the orthotopic neobladder, and fistula in a patient with duplicated collecting system are presented in the current study.

Conclusion:

Vesicouterine fistula after cesarean section (C/S) led to the formation of a huge intrauterine stone. Vesicouterine fistula is the least common form of fistula, and C/S is the most common cause of this type of fistula. However, this type of fistula is not always associated with urinary incontinence due to the cervix’s sphincter-like mechanism. Vesicocutaneous fistula is another uncommon type. Iatrogenic injury, extensive trauma, irradiation of malignancies, and various other etiologies, can lead to Vesicocutaneous fistula. For these cases, both conservative, and surgery can be considered. However, surgery is the only definitive repair method. Moreover, fistula in the junction of orthotopic neobladder to the vagina, and left ureter to vagina fistula in a patient with duplicated collecting system are among the strangest urogynecological fistulas.
