Stephen S. YangTaiwan Speaker UTI & Hydronephrosis: What's New and Asian Guideline UpdateHydronephrosis is a common urological condition in both adults and children. It is frequently associated with urinary tract infection (UTI). However, not all hydronephrosis means upper urinary tract obstruction (UUTO). So, differentiating hydronephrosis into pathological or physiological is important. In pathological hydronephrosis or UUTO, risk factors of UTI should be identified. While in physiological UTI, no further study is required. In this lecture, classification of upper urinary tract dilatation will be introduced, including SFU and UTD system. Other than intra-venous pyelourography, diuretic renal scan can be useful in differentiating hydronephrosis into physiological or pathological hydronephrosis. Pitfalls in interpreting diuretic renogram will be discussed. A brief review of risk factors of UTI will be done. Finally, Asian guideline on UTI will be updated.
