A ureteral fistula is an abnormal connection between the ureter and another organ or structure. It can cause symptoms such as pain, fever, and abnormal passage of blood, urine, or stool. Treatment usually involves surgical repair and antibiotics.
A ureteral fistula is an abnormal adhesion of a body structure to a ureter, which is the tube that carries urine from the kidney to the bladder. A fistula is an abnormal connection or opening between an organ or vessel and another body structure and usually occurs as a result of surgery, injury, childbirth, disease or infection. A ureteral fistula is a type of urinary fistula, which is an abnormal connection between one urinary tract organ and another organ or structure. In the case of a ureteral fistula, it is the ureter that has formed a connection with an organ or structure.
There are many different types of urinary fistulas. A ureteral arterial fistula, or anterioureteral fistula, is a communication between an artery and the middle or lower part of a ureter, which can cause hematuria or blood in the urine. A vaginal ureteral fistula, better known as a ureterovaginal fistula (IVF), is the abnormal connection of a ureter to the vagina, which can cause urine to leak from the vaginal opening.
There are other common urinary fistulas that do not involve any of the ureters. A vesicouterine fistula is a connection between the bladder and the uterus. A urethrovaginal fistula is a communication between the vagina and the urethra, which is the tube that drains urine from the bladder, and is found in both males and females. A colovesical fistula is a connection between the colon or intestines and the bladder, while a rectovaginal fistula joins the rectum to the vagina.
The most common cause of a fistula is surgery or an injury. A vasovaginal fistula, which is a connection between the bladder and the vagina, is the most common type of urinary fistula. It is usually caused by an injury to the bladder during surgery. Other causes of urinary fistulas include cancer, radiation therapy, and inflammatory diseases such as Crohn’s disease.
The symptoms of a fistula vary depending on which part of the body and which organs are affected. A ureteral fistula can usually cause flank pain, fever, chills, nausea, vomiting, abdominal pain, and abnormal passage of blood, urine, or stool. Diagnosis typically includes a pelvic exam by a doctor and one or more tests such as magnetic resonance imaging (MRI), ultrasound, computed tomography (CT or CAT), or cytoscopy. Treatment for a fistula usually involves surgical repair and the prescription of antibiotics if the condition is accompanied by an infection.
