I'm a 35-year old male and have suffered from recurring E. Coli infection in urinary track for the last 3 years. The infection comes back every time after I have sex. The infection is now controlled by antibiotics, but the E. coli strains are getting quite drug-resistant.
Multiple doctors have done many diagnostics -- urinanalysis/culture x-ray/CT over kidney/urinary track, ultrasound over bladder/testicles, comprehensive blood tests and checks for virus (HIV/RHR), cystoscope. Nothing wrong is found, except a mild mega-urethra which the doctor does not think is the cause. I have only one sex partner and my wife is healthy.
Anything else to look for?
