Final answer:
Obstructive uropathy in infants can manifest as decreased urine flow, UTIs, and hydronephrosis. Metabolic alkalosis and concentrated urine are not typically primary manifestations. Conditions like congenital hydronephrosis, kidney stones, and glomerulonephritis can cause these symptoms.
Step-by-step explanation:
Obstructive uropathy is a condition where the flow of urine is blocked which can lead to kidney damage. The clinical manifestations in an infant can include decreased urine flow, urinary tract infection (UTI), and hydronephrosis. Metabolic alkalosis is not typically a direct manifestation of obstructive uropathy, and while concentrated urine can sometimes be seen due to decreased urine output, it is not frequently noted as a primary clinical manifestation.
- Decreased urine flow is an expected finding due to obstruction.
- UTIs may happen secondary to the stasis of urine or kidney damage.
- Hydronephrosis, which is the swelling of a kidney due to urine build-up, can be caused by obstructive uropathy.
Diseases and disorders like congenital hydronephrosis, kidney stones, and glomerulonephritis are examples that can lead to the signs of obstructive uropathy.
