Urethritis is an inflammation ofthe urethra, the tube that carries urine from the bladder to the outside of the body. This inflammation, which is most often caused by an infection, can affect both men and women, although the clinical symptoms differ depending on anatomy.
Urethritis differs from cystitis (inflammation of the bladder) in its location, although the two conditions can occur simultaneously. According to the Haute Autorité de Santé and Santé Publique France, urethritis is primarily caused by sexually transmitted infections (STIs), most commonly Chlamydia trachomatis and Neisseria gonorrhoeae (gonococcus). Other infectious agents (mycoplasmas, Trichomonas, herpes viruses) or non-infectious factors may also be involved. Urethritis is one of the urinary disorders requiring a thorough medical evaluation.
The clinical presentation of urethritis involves several local signs. Their severity varies depending on the causative infectious agent and the patient’s underlying condition.
The most characteristic symptoms include a burning sensation during urination (dysuria), itching or tingling at the urethral meatus, urethral discharge of varying color and consistency (clear, yellowish, purulent), and sometimes pelvic or lower abdominal pain. In men, urethral discharge is often the primary presenting symptom. In women, symptoms may be more subtle, sometimes mistaken for other genitourinary conditions, and urethritis can be completely asymptomatic in certain forms (particularly those caused by Chlamydia), which delays diagnosis and increases the risk of complications. Urethritis can also cause persistent urinary pain requiring medical evaluation.
The diagnosis is based on a structured approach combining a medical history, physical examination, and targeted laboratory tests. It is exclusively within the purview of medical professionals.
The medical history takes into account the symptoms, their progression, and risk factors (recent unprotected sexual intercourse, multiple partners, history of STIs). The physical examination looks for urethral discharge, local tenderness, and any associated abnormalities. The laboratory tests recommended by the HAS include a urethral swab (or first-void urine sample in men) analyzed by multiplex PCR for Chlamydia trachomatis, Neisseria gonorrhoeae, and Mycoplasma genitalium. A comprehensive STI screening is routinely offered (HIV, syphilis, hepatitis B, hepatitis C). A bacteriological examination with an antibiotic susceptibility test may be performed in cases of gonorrhea to tailor treatment to increasing antibiotic resistance.
Treatment for urethritis is strictly medical and depends on the identified infectious agent. Self-medication should be avoided: it increases the risk of treatment failure and bacterial resistance.
Bacterial urethritis is treated with targeted antibiotic therapy and requires a doctor’s prescription. Current recommendations from the HAS and the French-Speaking Society of Infectious Diseases favor combination therapies that simultaneously target gonorrhea and Chlamydia due to the high frequency of co-infections. Viral urethritis (particularly herpes virus) requires specific antiviral treatment. Non-infectious urethritis (irritative, traumatic) requires elimination of the triggering factor. In all cases, treatment of the sexual partner(s) from the past two months is essential to prevent reinfection, in accordance with the recommendations of Santé Publique France. Cranberry extract and certain urinary comfort supplements may provide additional support, but they should never replace prescribed antibiotic therapy.
Untreated or inadequately treated urethritis can lead to serious, sometimes irreversible, complications. Early treatment is essential to prevent them.
Inmen, complications includeepididymitis (inflammation of the epididymis),orchi-epididymitis, acute or chronic prostatitis, and, more rarely, infertility due to ductal stenosis. In women, complications are of particular concern: upper genital tract infection with salpingitis (inflammation of the fallopian tubes), endometritis, pelvic inflammatory disease, chronic pelvic pain, ectopic pregnancy, and tubal infertility. During pregnancy, untreated chlamydial or gonococcal urethritis poses a risk of neonatal transmission (conjunctivitis, pneumonia). These complications justify screening, early treatment, and rigorous medical follow-up for diagnosed cases of urethritis.
Preventing urethritis relies primarily on preventing STIs, which are the leading cause of urethritis in France according to Santé Publique France. A few simple measures can significantly reduce the risk.
Consistent use of condoms (male or female) during any sexual intercourse with a non-regular partner or a partner whose HIV status is unknown remains the most effective preventive measure. Regular STI screening is recommended for sexually active individuals, particularly when changing partners or having multiple partners: it is free, anonymous, and available at CeGIDDs (Free Centers for Information, Screening, and Diagnosis). Gentle daily intimate hygiene using a pH-balanced intimate soap helps preserve the local protective flora. Systematic treatment of the partner(s) when an STI is diagnosed prevents reinfection. The human papillomavirus (HPV) vaccine and the hepatitis B vaccine complement STI prevention among young people.
Several risk factors increase the likelihood of developing urethritis. Identifying them allows for tailored prevention strategies and screening frequency.
The main risk factors include unprotected sex, particularly with multiple or casual partners; a personal history of STIs or a history of STIs in a partner; a new partner without prior screening; a weakened immune system (immunosuppression, immunosuppressive treatments, uncontrolled HIV infection). In women, certain invasive medical procedures (urinary catheterization, endoscopic examinations) can also contribute to urethritis. Engaging in certain high-risk sexual practices (unprotected oral or anal sex) increases the risk of urethritis caused by less common pathogens (Mycoplasma genitalium, herpes, enteric agents). Identifying these risk factors justifies regular screening during visits to a general practitioner, gynecologist, urologist, or at a CeGIDD clinic.
Urethritis affects both sexes, but its clinical presentation and complications differ due to specific anatomical and physiological differences.
Inmen, the urethra is long (15 to 20 cm) and entirely genitourinary. Urethritis is generally symptomatic, with marked urethral discharge, intense burning, and itching. Diagnosis is easier due to the obvious presenting symptom. In women, the urethra is short (3 to 4 cm) and anatomically more susceptible to infection. Urethritis in women is often less symptomatic or even completely asymptomatic, which delays diagnosis and increases the risk of severe gynecological complications (salpingitis, infertility, chronic pain). It is precisely this characteristic that justifies routine STI screening for young, sexually active women, particularly in cases of a change in sexual partner or multiple partners, even in the absence of symptoms.
A medical consultation is essential as soon as suggestive symptoms appear. The time between the onset of symptoms and seeking medical care directly affects the prognosis and the prevention of complications.
Prompt medical attention is required in cases of burning during urination,unusual urethral discharge, persistent genital itching or irritation, pelvic or lower abdominal pain, fever accompanied by urinary problems, or if there is any doubt following unprotected sexual intercourse. A primary care physician, urologist, gynecologist, or a CeGIDD clinic can manage the situation. An emergency consultation is necessary if you have a high fever, lower back pain, or signs of a severe infection that may indicate a complication. Do not wait for symptoms to disappear on their own: the apparent disappearance of symptoms does not mean you have recovered, and the infection may continue to progress silently toward complications.
Self-medication is not appropriate for urethritis. There are several medical reasons that strongly advise against it.
Diagnosing urethritis requiresprecisely identifying the causativepathogen through laboratory tests, a step that is impossible with self-medication. Antibiotic treatment requires a prescription tailored to the identified pathogen and its resistance profile: antibiotic resistance in Neisseria gonorrhoeae evolves rapidly and necessitates treatment protocols that are regularly updated by the HAS. Inappropriate self-medication can mask symptoms without eradicating the infection, promote bacterial resistance, delay proper treatment, and expose patients to irreversible complications. Additional STI screening (HIV, syphilis, hepatitis) can only be performed during a medical consultation. Treatment for the partner(s) also requires medical supervision. Temporary measures to alleviate symptoms (drinking plenty of fluids, taking pain relievers such as acetaminophen) can provide relief while waiting for a medical consultation, but they are in no way a substitute for a medical diagnosis.
Most cases of urethritis are sexually transmitted, but not all. This distinction is important for managing the condition and evaluating sexual partners.
Sexually transmitted infectious urethritis accounts for the majority of cases and is primarily caused by Chlamydia trachomatis, Neisseria gonorrhoeae (gonococcus), Mycoplasma genitalium, Trichomonas vaginalis, and, more rarely, the herpes simplex virus (HSV). Non-sexually transmitted urethritis does exist: it can be caused by non-sexual bacterial infection (spread of a urinary tract infection from the bladder, particularly in women), trauma (urinary catheterization, endoscopic procedures), irritative in origin (inappropriate hygiene products, spermicides, contact with certain fabrics), or allergic in origin. This diversity warrants a comprehensive medical evaluation that goes beyond a default diagnosis of an STI and helps guide treatment and preventive measures.
Some cases of urethritis may show apparent symptomatic improvement, but complete spontaneous resolution of infectious urethritis is rare and misleading.
Symptomatic improvement without treatment most often means that the infection has transitioned to a silent chronic form rather than a true cure. Chlamydia trachomatis, for example, can remain active in the body for months or years without symptoms, while causing irreversible tissue damage (particularly in the fallopian tubes in women). Contagiousness may persist during this asymptomatic period. For non-infectious urethritis (irritative, traumatic), spontaneous resolution is possible once the triggering factor is eliminated; however, the differential diagnosis with infectious urethritis requires medical evaluation. Relying on spontaneous recovery increases the risk of gynecological complications, infertility, or transmission of the infection to a partner. Prompt medical treatment remains the standard of care as soon as urethritis is suspected.
Screening relies on several complementary laboratory tests. The choice of tests depends on a medical prescription tailored to the clinical situation and risk factors.
The gold-standard tests, according to the HAS and Santé Publique France, include: multiplex PCR of urethral swabs or first-void urine in men for Chlamydia trachomatis, Neisseria gonorrhoeae, and Mycoplasma genitalium; vaginal and endocervical swabs in women using a similar PCR test; bacteriological testing with an antibiotic susceptibility test in cases of suspected gonorrhea to tailor treatment to resistance patterns; routine serological testing for HIV, syphilis, hepatitis B, and hepatitis C. Depending on the context, testing for Trichomonas vaginalis or herpes viruses. TROD (Rapid Diagnostic Screening Tests) for HIV are available at pharmacies or CeGIDD centers for initial screening. Screening is free, anonymous, and confidential at CeGIDD and CPEF (Centers for Family Planning and Education).
Allergic or irritant reactions can cause inflammation of the urethra, although this mechanism is significantly less common than infectious causes. Recognizing this helps avoid unnecessary antibiotic treatments.
Several irritants or sensitizing agents may be involved: unsuitable intimate hygiene products (harsh soaps, scented gels, wipes containing irritating preservatives), spermicides (particularly nonoxynol-9, which can damage the mucous membrane), lubricants containing fragrances or allergenic preservatives, latex in condoms in cases of latex allergy, and female contraceptives (vaginal ring, diaphragm) in sensitive women. The recommended course of action is to eliminate the triggering factor and use appropriate products: mild intimate soap with a physiological pH, polyurethane condoms in cases of latex allergy, and unscented water-based lubricants. A medical consultation is still necessary to confirm the non-infectious origin and rule out an associated STI.
Beyond the classic signs, some cases of urethritis present with less common symptoms that warrant prompt medical attention. Their appearance may indicate a complication or an associated condition.
Less common symptoms include urethral bleeding (outside of menstruation in women), pain during sexual intercourse (dyspareunia), chronic pelvic pain, and a fever that may suggest a complication (epididymitis, prostatitis, upper genital tract infection), lower back pain suggesting involvement of the upper urinary tract, associated joint pain that may indicate Fiessinger-Leroy-Reiter syndrome (post-infectious reactive arthritis), and skin or eye symptoms.The onset of any systemic symptom (fever, chills, deterioration in general condition) associated with urinary symptoms requires prompt medical evaluation, or even emergency consultation. Early management of these atypical forms is critical for a favorable prognosis and the prevention of long-term complications.
