Repeated Urinary Infectio. Out on this.

Dear Doctor, The problem is with my 1-year-old Niece, currently in Dubai. She has been having repeated urinary infections and after further checkup, the doctor there determined that she had a blockage in the upper part one of her kidneys which was causing her repeated infections. The doctor there recommends she have that portion of her kidney removed. Until then she is put on daily dosage of Septrin- Paediatric Suspension (Trimethoprim-Sulfamethoxazole). I would like to get a second opinion on the same and would be glad to follow up on the same towards the second week of October when they are visiting India. I am attaching copies of a nuclear scan (99mTc DTPA Diuretic Renal Scan), micturating cystourethrogram, and CT abdomen & Pelvis. Would be great if someone can help us out on this.
