trrett · Guest **posting in usmle forum about USMLE Step 2 CK**

A 65-year-old woman is admitted to the hospital for constant, severe abdominal pain that has worsened over the prior week. She has no other associated symptoms, such as nausea or vomiting, but has noticed that her daily urine output has sharply decreased. She has had a constant desire to urinate, but, when she tries, only a small amount of bloody urine is discharged. The patient is a long-time smoker, having smoked three packs per day for more than 45 years, although she claims to have quit 2 days ago. A bladder ultrasound in the emergency department reveals a mass consistent with bladder cancer, as well as significant urinary retention. Which of the following is most likely to be detected upon imaging the patient's genitourinary system?

A. Bilateral hydronephrosis
B. Bladder dilation
C. Bladder dyskinesis
D. Unilateral hydronephrosis
E. Ureteral dilation
