Answer to Question 1

ANS: B
Pyelonephritis is a bacterial infection of the renal pelvis and parenchyma, typically caused by Escherichia coli ascending from the lower urinary tract. The patient will have bilateral or unilateral flank pain, fever, chills, nausea, and vomiting, and LUTS, such as dysuria, may also be present. The patient will appear ill on presentation, with fever and tachycardia commonly noted. Palpation and/or percussion over the infected side is painful. There may be accompanying abdominal discomfort or abdominal distension.

Answer to Question 2

ANS: B
Approximately 80 to 90 of patients with bladder cancer present with painless gross hematuria. All patients with this classic presentation should be considered to have bladder cancer until proof to the contrary. Patients should be referred to a urologist. They usually undergo cystoscopy to rule out bladder tumor. The majority of patients with bladder cancer present with no urinary tract symptoms or palpable masses.
