A recurrent urinary tract infection (recurrent UTI) is defined as the occurrence of two or more urinary tract infections in a six-month period or three or more infections in a year. These infections can affect any part of the urinary system, including the urethra, bladder, ureters and kidneys, with bladder infections (cystitis) being the most common.
Causes can vary, including anatomical factors, sexual activity, hormonal changes, and certain underlying medical conditions. Recurrent UTIs require careful medical evaluation to identify and treat predisposing factors and develop appropriate preventive strategies.
A patient with recurrent urinary tract infections must be well informed about various aspects to effectively manage and prevent these infections. Here is a detailed guide:
1.- Definition of recurrent urinary tract infections:
Recurrent UTIs are generally defined as two or more infections in six months or three or more in a year. Common causes include bacteria such as Escherichia coli, anatomical factors, sexual intercourse, hormonal changes, and certain underlying medical conditions.
2.- Symptoms:
Typical symptoms include pain or burning during urination, frequent and urgent need to urinate, pain in the lower abdomen, cloudy or foul-smelling urine, and fever in severe cases.
3.- Prevention:
- Maintain good personal hygiene, especially before and after sex.
- Drink plenty of water to help flush bacteria from the urinary tract.
- Urinate regularly and do not hold urine for long periods.
- Wear cotton underwear and avoid tight-fitting clothes.
4.- Treatment:
- Follow your doctor’s guidelines for the use of antibiotics. In some cases, prolonged treatment or a low dose of antibiotics may be necessary as a preventive measure.
- Analgesics for pain and other specific medications as appropriate.
- Autovaccination is a therapeutic approach used to treat recurrent urinary tract infections (UTIs) when conventional treatments are not effective or when an alternative to continuous antibiotics is sought. This method involves creating a customised vaccine from the patient’s own bacteria, specifically those that are causing the recurrent infections.
- Perform additional studies to rule out anatomical abnormalities or underlying conditions that predispose to UTIs.
5.- Lifestyle and habits:
- Avoid bladder irritants such as caffeine, alcohol and spicy foods.
- Manage other medical conditions that may contribute to UTIs, such as diabetes.
6.- Consultation and follow-up:
Follow up regularly with the urologist or primary care physician to monitor and adjust treatment as needed.
