Hello and welcome to HCM
You are either suffering from UTI with Renal Stones
. You need to go for USG lower abdomen to rule out cause of obstruction as you have leaking problem and Urine examination and culture examination. Leakage may be due to any stone or Increased Prostrate gland which is more common at your age.
For treatment of stones and UTI take a course of antibiotic, plenty of water, diuretics, Citrus Soda and other alkaliser and at least may need surgical procedure. If it comes to be BPH than you need alpha blockers or surgery depending upon the report of USG.
So don't worry and consult your doctor and get a proper treatment.
