What is a common complication of untreated urinary tract obstruction?

Hydronephrosis is indeed a common complication of untreated urinary tract obstruction. When there is an obstruction in the urinary tract, urine can accumulate in the kidneys, leading to swelling and distension, known as hydronephrosis. This condition occurs because the obstruction prevents normal urine flow, allowing fluid to back up into the renal pelvis and calyces. If this obstruction is not addressed, the increased pressure and accumulating fluid can cause damage to renal tissue, impair kidney function, and ultimately lead to kidney failure.

Prompt diagnosis and management of urinary tract obstructions are crucial to prevent hydronephrosis and its associated complications. Monitoring and imaging studies, such as ultrasound, can help visualize the obstruction and guide appropriate treatment strategies to relieve the pressure and restore normal urine flow.
