Urine leakage
This leakage can be anything from a few drops to large quantities of urine. This leakage can be caused by the muscles in the pelvis not being able to keep a tight fit on the urethra.
Difficulties emptying your bladder
Your urine has difficulties flowing out if there is some kind of obstacle in your bladder or urethra. Problems emptying your bladder can also be caused by trouble contracting your bladder muscle when it's time to empty your bladder.
UTIs (urinary tract infections)
UTIs are a common problem, that mean that bacteria are allowed to grow. This can lead to both urine leakage and problems emptying your bladder.
Kidney problems
One or both of your kidneys' functionality can be reduced, which also leads to problems with your bladder and urination.
