question: Hi Sir / Madam,My Dad (Mr. Maruti M.Shirodkar) is suffering from Parkinson since last 10 years, however along with PD he is going through a rough patch of having E-coli bacteria in urine at regular interval. We had operated him for prostrate twice, however have noticed that he is not able to pass his urine completely and because of this bacteria (E-coli) is found in his urine. Intake of antibiotics help to reduce the count of bacteria, however after a interval this antibiotics become resistance to it. Please suggest in this scenario which doctor I need to consult a urologist or a nephrologist, also is there a permanent solutions for the same. A urologist also said that his urinary bag in body may have got weak because of which he is not able to vacate urine completely Regards,Ameet Shirodkar
