HI all Docs,
Here my new topic & I'll talk about different cases in different specialities the goal from that is to share medical knowlegde with all of u and any one who know have a note or a case which we may benifit all, and since I have a UROSURGERY coarse I will begin with a uro case:
A 61-year-old man presents with a chief complaint of painless hematuria. He has had 6 episodes over the past 2 years. For approximately 1 day, he had several episodes of hematuria followed by the passage of blood clots the next morning. He denies having trauma, flank pain, dysuria, urinary frequency, fevers, or weight loss. He denies traveling outside the country. He has not had any recent surgery, catheterization, or other procedure involving instrumentation. He has no chronic medical problems and specifically denies a history of renal stones. He denies drug use, He smoked cigarettes for 25 years but quit 2 years ago.

The patient's physical examination is unrevealing. He has no palpable masses, abdominal or costovertebral tenderness, prostate enlargement or tenderness, or penile abnormality. Laboratory studies show mild normocytic anemia with a normal coagulation profile. Urinalysis reveals a large amount of RBCs.
And the following Imaging was done:

The questions in this case:
1) Why drug hx is important & what drugs cause hematuria?
2) Why we do IVP & not ultrasound?
3) What benifit of ct scan in this case?
4) What is the D.Dx?
5) Is ciggarette smoking in this patient a clue to Dx?
6) What ubnormal findings u see in radiological Ix?
Thanks, hope to see ur answers.
