My father is suffering from cystitis with hematuria, since 3 months. His ct scan report is as follows- 7 mm calculus is seen at rt Vesuvius- ureteric in bulging in the bladder lumen. It is persistent at its rt Vesuvius- ureteric jn even in prone position. No proximal hydronephrosis or hydroureter is seen. He was in LVF & had an acute coronary syndrome 3 months back. No coronary angiogram was done. He had also suffered a pulmonary emboli in July 2016. At present he is on following meds-flavedon mr, monotrate 30, lasix 40 mg, 1/4 tab, cardivas6. 25 mg & clopilet7 mg. For his UTI he has taken fosfomycin 3 mg & Zifi-cv (200) mg. Kindly advise if we can consecutively treat him for his calculus as we are against surgery considering his cardiac status & age.
