Dernièrement, j'ai parlé du premier épisode de l'infection de la vessie. C'est ce qu'on appelle la "cystite aiguë". Même après avoir suivi un traitement approprié, de nombreux patients se plaignent encore d'une infection récurrente de la vessie tout au long de l'année. Le terme médical de l'épisode de réinfection de la vessie malgré l'offre d'un traitement approprié est appelé "cystite récurrente"
The bladder infection episodes that has occurred 2 times or more than that within 6 months, or 3 times or more within the past year, would be considered as “Recurrent cystitis”. Greater than 30% of women who complaint recurrent bladder infection was reported. This kind of problem wouldn’t be life-threatening but it significantly affects quality of life.
There are 2 widely accepted mechanisms for infection récurrente de la vessie.
- Bacterial factors – Escherichia coli is the most common cause. Certain strains have a unique ability to attach to vaginal mucosa and hide inside bladder cells during antibiotic treatment, then re-emerge after the course is completed, triggering a new infection episode.
- Host factors – Compromised immunity makes patients more susceptible to reinfection, with more frequent and more severe episodes. Maintaining overall health and keeping chronic underlying conditions well-controlled is key.
Beside these 2 mechanisms, there are several modifiable risk factors that urologists evaluate and address:
- Behavioural factors – Frequency of sexual activity, multiple sexual partners, and use of certain vaginal agents are important risk factors, especially in young women. Urinating once immediately after sexual intercourse is a simple and evidence-supported preventive recommendation.
- Urinary tract anatomy factors – Imaging evaluation can detect correctable causes such as kidney stones or urinary obstruction that contribute to recurrent infection. Specific management depends on the identified cause.
- Residual urine factor – Incomplete bladder emptying leaves urine in the bladder, creating a favorable environment for bacterial growth. Evaluation and management of residual urine is an important component of the urological workup.
- Hormonal factor – Postmenopausal women with estrogen deficiency have reduced vaginal Lactobacilli, which normally help prevent bacterial invasion. Topical estrogen replacement can restore this protective flora.
If you have any questions, don’t hesitated, give me message or PM moi.

Frequently Asked Questions about Recurrent Bladder Infection
Recurrent cystitis is defined as two or more bladder infection episodes within 6 months, or three or more episodes within a single year, despite completing appropriate antibiotic treatment. It affects more than 30% of women who have had an initial bladder infection and significantly impacts daily quality of life, though it is not life-threatening.
Some strains of E. coli have a unique survival strategy – they attach to vaginal mucosal cells and hide within bladder lining cells during antibiotic treatment, then re-emerge once the antibiotic course ends. This bacterial persistence mechanism is a primary reason why infections recur even after seemingly successful treatment.
Yes, sexual activity is a well-established risk factor for recurrent UTI in women. Frequency of intercourse, multiple partners, and use of spermicides all increase risk. A simple and effective preventive measure is to urinate once immediately after sexual intercourse, which helps flush bacteria from the urethra before they can ascend to the bladder.
Yes. After menopause, declining estrogen levels reduce the natural Lactobacilli population in the vagina. These beneficial bacteria normally form a protective barrier against E. coli invasion. Loss of this flora increases bladder infection susceptibility. Intravaginal topical estrogen cream is an evidence-supported treatment to restore vaginal flora and reduce recurrence in postmenopausal women.
You should consult a urologist if you experience 2 or more bladder infections within 6 months, or 3 or more in a year. A urologist will perform a comprehensive workup including imaging to rule out kidney stones, urinary obstruction, or residual urine, and will develop an individualized prevention strategy that may include non-antibiotic supplements, hormonal therapy, or long-term prophylaxis.
