There are two possibilities for urine odor, especially for male patients who are more likely to occur. One situation is that the foreskin is too long, if the foreskin is too long, there is a large amount of secretion in the foreskin, usually not in time to turn over and clean, after the combined bacterial infection inside, there will be a significant bad smell when urinating, mainly due to the secretions on the glans, this situation urine is normal. Another situation is that there may be infections such as E. coli in the urine, resulting in an abnormal foul odor in the urine discharged. It may also be because there is a fistula between the urinary system and the intestines, resulting in an infection. This situation suggests that you must go to a regular hospital urology department for an examination to observe whether it is caused by circumcision or by a urinary fistula.
