Of 113 intravenous pyelograms, functional changes revealed non-visualization 46.9%, delayed visualization 27.6%. The itemized classification based on Braasch and Emmett was similar order of frequency as original. Lattimer Grade IV and far advaced case were the most frequent in 30 retrograde pyelograms. Nephrectomy was 95% in 104 operated cases and 92 nephrectomized specimens disclosed all parenchymal tuberculous nodules, tuberculous mucosal lesion in 82%, cavities 70%, calcification 4.3%, and pyonephrosis 17%.
