Hello, * As per my surgical experience, the issue with your urinary system sounds to be secondary urinary tract infection following calculus or gravels in the urinary system. * As there are antibiotics killing the microbes symptoms improve, but still the root cause is inside which is repeatedly infecting the system. * Kindly get an ultrasound of the abdomen & pelvis done for the precise diagnosis and further management in accordance to that only to cure the condition at earliest. * Meanwhile citrus fruits and urinary alkaliser as liquid renalka or else will help for sure. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Bhagyesh V. Patel, General Surgeon
