The adrenal cortex function is essential for life. (True or False)

A. A 69-year-old female with anemia secondary to insufficient erythropoietin production: While anemia can occur due to chronic kidney disease, it does not directly cause urinary tract obstruction. The lack of erythropoietin affects red blood cell production, not urine flow.

B. A 70-year-old male with benign prostatic hyperplasia (BPH): BPH is a common cause of urinary obstruction in older men. The enlarged prostate compresses the urethra, leading to impaired urine outflow and increased risk of urinary retention.

C. A 58-year-old male with renal calculi: Kidney stones are a frequent cause of urinary tract obstruction. They can block the flow of urine in the ureters, renal pelvis, or bladder, leading to pain, hydronephrosis, and infection risk.

D. A 29-year-old female, pregnant for the first time: Pregnancy can cause urinary obstruction due to the enlarged uterus compressing the ureters, especially in the second and third trimesters, resulting in reduced urine flow and potential hydronephrosis.

E. A 28-year-old male with a neurogenic bladder secondary to spinal cord injury: Neurogenic bladder disrupts normal bladder function and control, which can lead to urinary retention and obstruction due to poor coordination of bladder muscle and sphincter activity.

F. A 43-year-old male with an acid-base imbalance secondary to malnutrition: While malnutrition can affect many organ systems, acid-base imbalance by itself is not a direct cause of urinary tract obstruction.

A. Renal agenesis: failure of an organ (renal) to develop: Renal agenesis is the complete absence of one or both kidneys due to failure of development during fetal life. Bilateral agenesis is often fatal, while unilateral agenesis can be asymptomatic if the remaining kidney functions well.

B. Renal hypoplasia: failure of kidney to develop to normal size and contains fewer renal lobes: In renal hypoplasia, the kidney is structurally normal but smaller than average and contains fewer nephrons or lobes. This congenital condition may be unilateral and asymptomatic or bilateral and lead to renal insufficiency.

C. Renal dysgenesis: failure of an organ (kidney) to develop normally: Renal dysgenesis refers to abnormal development of the kidney structure, resulting in malformations that can impair function. It often involves malformed or nonfunctional renal tissue.

D. Renal dysgenesis: failure of an organ (kidney) to develop: This description better defines renal agenesis rather than dysgenesis, which implies abnormal rather than absent development.
