My brother has the below kidney problem and request you to suggest what is the next step. Whether he has to undergo surgery or with the medication it can be rectified. Right sided moderate hydro nephrosis with hydro uretra due to calculus in the lower 1/3rd ureter(below the level of iliac vessels crossing) measuring 6.4mm(along short axis of the ureter) x 9.7mm(along long axis of the ureter) with distinct post acoustic shadowing.
The chances of his calculus getting out on his own is minimal as the size of the stone is more than 3 mm. Also, it is causing blockage resulting in back pressure changes that is swelling of kidney and ureter. The more you wait, the more chances of irreversible damage to your kidney. Hence, it is best to get the stone removed through cystoscope (endoscopic) surgery at the earliest.
