Objective . To describe the sonographic appearance of ureteric obstruction due to necrosed papillae. Methods . In this study, carried out over 3 years 6 months, patients with diabetes mellitus who had renal colic were studied by sonography. Results . In 15 patients with hydronephrosis, there was a soft tissue mass of necrosed papillae filling the ureteric lumen at the site of obstruction. Necrosed papillae were seen in medullary cavities of the ipsilateral kidney in 5 patients. Ureteroscopic removal of necrosed papillae was done in 13 patients. One patient was not fit for an invasive procedure. Conclusions . When patients predisposed to renal papillary necrosis have renal colic, and sonography fails to show a ureteric calculus, it is best to look for necrosed papillae in the ureter, which may be causing obstruction.
