What’s your diagnosis, based on this abdominal ultrasound? I’ll post the correct answer in a few days!
Correct answer: Hydronephrosis. Note the dilatation of the renal pelvis and clubbed calyces. After diagnosing acute retention and placing a cathether, the bladder residual can be as much as 1,5 L of urine. Don’t be surprised to be told by the biochemistry lab that the serum creatinine is 1500 micromol/L!
