Hello Sir, My husband, 27 yrs old developed kidney stones 3 months back. On 29th Aug he had acute pain. The ultrasound reports showed hydronephrosis and a calculus in the midpole region of right kidney and also 3.8 mm of calculus at uretovesical junction of right ureter. He was on medication for 2 weeks continously that mainly consisted of magnesium citrate solution, antibiotics (ampicillin group) and urine infection suppressents. He again underwent an ultrasound on 14th Sep which says no hydronephrosis and no calculus in right kidney but the right kidney shows fullness of pelvicalyceal system. Doctor, please help me to understand this term. Is it something serious? I stay in a very small town. Have we to go to a city for its treatment?
