Ureteritis – Symptoms, Diagnosis, and Treatment of Inflammation of the Urinary Tract

The ureter should not be confused with the urethra. While the paired ureters carry urine from the kidneys to the bladder, the urethra carries urine out of the body.

The urinary tract. 1: Kidney. 2: Renal pelvis. 3: Ureter. 4: Bladder. 5: Urethra

Women are at a higher risk than men of developing a urinary tract infection. Because the urethra is shorter in women, bacteria can travel more quickly toward the renal pelvis. In addition, approximately one in three pregnant women experiences a urinary tract infection at least once.

Ureteritis can have various causes.

In most cases, the infection results from a urethral or bladder infection, during which bacteria travel up into the ureter. A urethral infection is often caused by bacteria such as chlamydia, gonococci (gonorrhea), or intestinal bacteria. Chlamydia and gonococci are usually transmitted through unprotected sexual intercourse. Intestinal bacteria can enter the ureter through smear infections, for example, by wiping the anal area incorrectly after using the restroom.

Other possible causes:

• Viruses such as herpes simplex or fungi
• Allergies to certain contraceptives and lubricants
• Younger women are particularly susceptible to bladder infections—especially in colder temperatures—which can develop into a ureteral infection.
• People with ureteral stones have an increased risk of developing inflammation of the ureteral mucosa. The stones block the flow of urine and irritate the mucous membranes in the ureter, making it easier for bacteria to colonize the area.

The symptoms of ureteritis are very similar to those of a pyelonephritis. Typical symptoms include:

• Pain in the kidney area that may radiate to the abdomen and back
• Pain when urinating
• Frequent urge to urinate
• Fever
• Chills
• Nausea
• General feeling of illness
• Constipation

Ureteral infections are very common in older adults aged 65 and older. However, the symptoms are less pronounced, so the infection often goes unnoticed and people rarely seek medical attention.

The first step in diagnosing ureteral inflammation is a detailed consultation with the doctor. The doctor will ask the patient about their medical history and symptoms. During the consultation, the doctor should also inquire about the patient’s sexual behavior (frequent changes in sexual partners, unprotected sex, use of contraceptives and lubricants).

Since ureteritis is usually accompanied by an infection of the urethra or bladder, the doctor will examine the urinary tract for bacteria. Urine tests are performed for this purpose. A rapid test for bacteria using urine test strips can confirm a suspected urinary tract infection. A swab from the urethra also provides clues about the cause of the infection. To confirm the diagnosis and identify the specific pathogen, urine cultures are prepared in the laboratory and bacteria are cultured. If chlamydia is suspected, women may also undergo a cervical swab.

The specific site of the inflammation (bladder, ureter, renal pelvis) can only be identified using complex methods such as ureteroscopy or cystoscopy; however, this is usually not necessary. Identifying the pathogen is generally the only factor crucial to successful treatment.

Treatment for ureteritis depends on the pathogen causing the infection and should be initiated as early as possible. If bacteria are the cause of the infection, the doctor will prescribe antibiotics. If fungi or herpes viruses are involved in the urinary tract infection, antifungal medications (antimycotics) and antiviral medications are used. If an allergy to contraceptives is suspected, they must be discontinued and alternatives sought.

In addition to medication, there are measures that can support and speed up the healing process. For example, it is important for the patient to drink plenty of fluids and urinate as often as possible, even if urination is painful. This helps flush out the pathogens more effectively. The lower abdomen and feet should be kept warm, as warmth stimulates blood circulation and strengthens the immune system. If the infection is sexually transmitted, you should refrain from sexual intercourse during treatment.

The prognosis for ureteritis is generally very good. With timely treatment, symptoms often disappear within a week at the latest. However, if the infection has already spread significantly toward the renal pelvis, treatment takes longer. In very rare cases, ureteritis can lead to life-threatening complications and result in an acute infection with blood poisoning (urosepsis). It is therefore very important to see a doctor at the first signs of a urinary tract infection.

What is ureteritis?

Ureteritis is an inflammation of the ureters within the urinary tract. The condition is usually caused by a bacterial infection with pathogens such as Escherichia coli, chlamydia, or gonococci. The inflammation often spreads from the bladder or urethra to the upper urinary tract.

What are the symptoms of ureteritis?

Typical symptoms of ureteritis include pain when urinating, a burning sensation in the urethra, lower abdominal pain, and discomfort in the kidney area. Some pain may radiate into the back. In addition, urinary tract infections, bladder infections, or inflammation of the bladder often occur.

How is ureteritis diagnosed?

Diagnosis and treatment usually involve a urine sample, urine tests, and a physical examination. Additionally, a swab or swabs may be taken from the urethra to identify the exact pathogen causing the infection. In complicated cases, ureteroscopy or cystourethroscopy may be used.

How is ureteritis treated?

Antibiotic therapy usually involves an antibiotic effective against the causative bacterium. Home remedies such as sitz baths, full-body baths, or chamomile extract can also help by promoting blood circulation in the lower abdomen. It is also important to drink plenty of fluids to flush the bacteria out of the urinary system.

What complications can ureteritis cause?

If left untreated, the infection can spread from the ureter to the kidney or renal pelvis and cause serious complications. In rare cases, it can lead to urosepsis or chronic urinary tract disorders. The risk of developing ureteritis is particularly high in cases of ureteral stones, fungal or viral infections, and unprotected sexual intercourse.
