The full form of RPD in medical term is “Renal pelvis dilatation.”
Renal pelvis dilatation, also known as hydronephrosis, is a condition that occurs when urine builds up in the kidneys, causing the renal pelvis to become enlarged. The renal pelvis is a funnel-shaped area in the center of the kidney that collects urine and funnels it down to the ureter, which carries it to the bladder. When the renal pelvis becomes dilated, it can cause various symptoms and be a sign of an underlying medical condition.
There are several causes of renal pelvis dilatation, including urinary tract obstructions, such as kidney stones or tumors, ureteropelvic junction (UPJ) obstruction, and vesicoureteral reflux (VUR).
Diagnosis of renal pelvis dilatation typically involves imaging tests, such as ultrasound or CT scan, to visualize the kidneys and urinary tract. The severity of the dilation is graded based on the size of the renal pelvis and the degree of hydronephrosis. Treatment options depend on the condition’s underlying cause and the severity of symptoms.
In cases where the cause of renal pelvis dilatation is a urinary tract obstruction, treatment may involve the removal of the obstruction through surgery or using a stent to keep the urinary tract open. Medications may sometimes be prescribed to relieve pain or treat infections. In cases where a congenital abnormality causes the condition, treatment may involve ongoing monitoring and management of symptoms.
