A 70-year-old man comes to the physician because of a 2-year history of
urinary hesitancy and frequency. He states that he wakes two to three times
a night to void, and that during the past year he has had intermittent pain
with urination. Physical exam shows no abnormalities. Results of a
urinalysis are within the reference range. Ultrasonography of the abdomen
shows bilateral dilation of the renal collecting system. Which of the
following is the most likely diagnosis?
A) Adenocarcinoma of the prostate
B) Benign prostatic hyperplasia
C) Nephroblastoma (Wilms tumor)
D) Renal cell carcinoma
E) Ureterolithiasis
F) Ureteropelvic junction stricture
G) Urethral valves
H) Urothelial carcinoma of the bladder
请问这题是什么答案啊？
如果是 B) Benign prostatic hyperplasia， 为什么体检 Physical exam shows no
abnormalities？
如果是 E) Ureterolithiasis， 为什么 wakes two to three times a night to void
另外 during the past year he has had intermittent pain with urination 中的
pain是什么意思啊？感染？为什么又一过性的自己好了？像是结石的样子？
多谢了！！！

顶着个锅盖来猜答案
是B？因为有些前列腺纤维性增生的话其实体积不会增大，有些反而会小，只是硬化后
压迫尿道。所以体检说没什么异常。
E 的话超声一下就看出石头了，这个超声却只说肾的变化。感觉没道理呀
