Male urinary tract infections (MUTI) are often less recognised compared to those in women. French clinical guidelines practices recommend the use of antibiotics called fluoroquinolones, which are highly effective in treating MUTIs. However, these antibiotics can lead to rare but serious side effects, such as tendonitis or heart rhythm disturbances. Additionally, fluoroquinolones can contribute to the development of bacterial resistance, making their use inadvisable within six months of treatment.
In response to these concerns, we aim to explore a well-established alternative, fosfomycin trometamol (known by the brand name MONURIL®). This antibiotic has a strong track record in treating UTIs in women, with well-documented benefits and minimal associated risks.
The primary goal of this study is to assess the effectiveness of fosfomycin trometamol in treating urinary tract infections in men, as well as to evaluate any potential treatment failures.

Exclusion Criteria:
Presence of one or more criteria for severity of infection
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Single-Arm The treatment studied is fosfomycin trometamol (FT): FOSFOMYCINE ARROW ADULTS 3 g, granule for drinkable solution in sachet. FT is available in generic form. It comes in a sachet of 3 g of granules for oral solution (orange flavour). In this study, FT will be taken to treat a non-febrile male urinary tract infection, at a dosage of 3 g per day every 2 days for 14 days, i.e. 7 doses (D0, D2, D4, D6, D8, D10, D14). Seven sachets, accompanied by a prescription specifying the dosage, will therefore be given to the patient on inclusion in the study.
