What does the following kidney function test report indicate?
Patient: Kidneys Test (10/02/2014): FINDINGS: There is mild right hydronephrosis/extra renal pelvis. The kidneys are normal in size, contour, cortical thickness and cortical echogenicity. Right kidney: 13.7 cm. Left kidney: 12.8 cm. There is normal renal perfusion. No renal calculi are identified. There is no evidence of hydronephrosis. No renal mass the as identified. IMPRESSION: Mild right hydrophones/extrarenal pelvis. Otherwise unremarkable kidneys (normal) Should I worry, Dr.? Doctor: Hi,Thanks for writing in.The left kidney is normal in size and appearance.The right kidney size is normal but there is an appearance described as increased fullness of the renal pelvis. The renal pelvis connects the kidney collecting system to the ureter. In your case, there is no infection or stone which is causing obstruction to flow of urine. However this can be seen in normal people due to increased pressure of urine in the kidney or also as a normal variant from birth.It is suggested that you please get the ultrasound scan done after passing the urine and this will confirm any back pressure effects on the right kidney. In most cases it does not require treatment. Please do not worry.
