Simple renal cyst
Or renal epithelial cyst

They are the most common type of renal cysts. The incidence increases with age. Approximately 25% of people who are 40 years or older and approximately 50% of people 50 years and older have simple kidney cysts.

They are mostly asymptomatic and detected incidentally upon radiological exams of the abdomen or at autopsy. And they can be bilateral. Management is not required unless the cyst becomes infected or enlarges and causes symptoms.

If a cyst becomes infected, antibiotics are necessary. If a cyst is so large that it is exerting mass effect or pressure on another organ, the two most common procedures for treating simple kidney cysts are (1) aspiration and sclerotherapy and (2) laparoscopic surgery to remove the cyst. Ethanol is most commonly used in sclerotherapy.

Signs and symptoms of cystic renal cell carcinoma include:

- Macroscopic hematuria (in 60% of patients)
- Flank pain (40%)
- Palpable flank mass (30-40%)

But only 10-15% of patients will present with the classic triad of symptoms.

Aortic coarctation

Normally the blood pressure in the legs is the same or higher than that in the arms. But because of the narrowing of the aorta, patients with aortic coarctation provide less blood to the lower half of the body than normal. And because there’s less blood, the blood pressure taken in the legs would be lower rather than higher.

أبوابُ بيتِكَ هذا الليلَ موصَدَةٌ
والسورُ حتى لِسَيلِ الدَمعِ لَم يَحِدِ

هذهِ الأرضُ ما ضاقَت على أحَدٍ
فكيفَ يا ربِّ ضاقَ الكونُ في أحَدِ

أمشي وقامَةُ حُزني طولَ مأذنةٍ
وكُلُّ ما كَتَبَ الزيتونُ مُعتَقَدي
