what sort of problem she is having during micturation?burning muctiration?does urine contains blood? ie red or pinkred coloured urine? you need to get urine analysis by consulting UROLOGIST
in your area, bcoz it likely any person old age should be comeout from renaltb, any mass anywhere along tract should be ruled out first,if infection is cause,must be treated at earlist, otherwise things vl end up in renal failure
take one cap pan-d befor breakfast in morning,then she can take akt4
,all tabs in 1/2 hour after food preferably with fruits,gradually she vl over come from gastric problem as you told,remember you never stop giving akt4 just bcoz of gastric, otherwise she may develop multidrug resistanceTB,which is incurable.any way take care,gud luk.
