I am 60 years old and having enlarged prostate of size 4.2*3.8*4.3 cm. Vol 35.3 cc. However, the ultrasound of whole abdomen shows a couple of calculi in upper calyceal region, largest of approx dm. 7 mm. Ureter not visualized. Now I am taking Homeopath medicine (Pichi-Q and Berberis vulgaris 30 (German). Please prescribe any allopathic or ayurvedic medicines are available for removal of calculi. Further, what are the reputations of such condition and if surgical intervention is safe or recommended. Thanks.
