Renal colic due to sloughed papilla

Case contributed by Maulik S Patel
Diagnosis almost certain

Presentation

Diabetic male with right loin to groin pain for last two days. Fever for last one day.

Patient Data

Age: 55 years
Gender: Male
ultrasound

There is a small focus at the right vesicoureteric junction. Its echogenicity is higher than the ureteric wall / urinary bladder wall. Right-sided hydroureter and hydronephrosis are present. A right renal lower calyx shows focal dilatation and irregular shape. There is a small non-mobile mildly hyperechoic area in the calyx.

Mild urothelial thickening is present in both kidneys. Both kidneys are normal in size without calculus/ mass lesion.

Case Discussion

A diabetic male presented with right renal colic. The ultrasound findings raised a possibility of a sloughed papilla from the right renal lower calyx resulting in vesicoureteric junction obstruction.

CT urography (not uploaded, no copyright) was done later which suggested right renal lower calx papillary necrosis with sloughed papilla at the right vesicoureteric junction.
