Sonographic features of necrosed renal papillae causing hydronephrosis.

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.

Sonography of pancreatic ductal anatomic characteristics in annular pancreas.

Annular pancreas is a rare developmental anomaly of the pancreas. The sonographic feature of this condition has been described as circumferential pancreatic tissue around the duodenum. Diagnosis of this condition by the sonographic visualization of ductal anatomic characteristics is described here.

Perineal sonography in diagnosis of an ectopic ureteric opening into the urethra.

OBJECTIVE: To study the role of perineal sonography in the diagnosis of an ectopic ureteric opening into the urethra. METHODS: In this study, carried out over about 4 years, perineal sonography was done to look for a ureter opening ectopically into the urethra in patients for whom abdominal sonography showed the ureter descending below and beyond the urinary bladder. RESULTS: Perineal sonography was done on 11 patients because there was a suggestion of an ectopic ureteric opening shown on abdominal sonography. In all of them, an ectopic ureteric opening into the urethra was shown on perineal sonography. The collecting system was seen to be nonduplicated in 6 patients and duplicated in 4 patients, and a triple ureter was present in 1 patient. CONCLUSIONS: Perineal sonography is a simple, quick, beneficial, and noninvasive technique that can be used as an extension of abdominal sonography to diagnose an ectopic ureteric opening into the urethra.
