Unspecified obstruction of the renal pelvis and ureter means some unknown substance or growth is blocking the outflow of urine from that kidney.

Renal Pelvis
This is a condition in which there is dilatation of the renal pelvis, the kidney part that is in direct connection with the ureter. The ureter is in direct communication with urinary bladder. If urinary bladder infection occurs, transmission through the ureter to the renal pelvis may occur resulting a more serious infection known as pyelonephritis which was reported to be more common in children born with pelviectasis. Pyelonephritis can cause chronic renal damage. Pelviectasis is usually diagnosed in the prenatal period or shortly after in newborns and is thought to be a self limited that resolves later. Dilatation in the renal pelvis in adults occurs when obstruction below the kidney level occurs either in the ureter or in the bladder near the ureteric orifice (like stones, fibrosis). Back pressure will cause changes in the kidney usually in the form of renal pelvis dilatation and calcyeal dilatation.
Into the ureter.
Hydrouretonephritis is the distention and dilation of the renal pelvis and calyces, caused by the obstruction of free flow of urine from the kidney. Its like having water inside the kidneys.

Pyelotomy is surgical incision into the renal pelvis. A related term, pyeloplasty, is surgical repair of the renal pelvis.
renal pelvis
The ureter joins the kidney at an area called the renal pelvis.The renal Pelvis
Renal pelvis acts as the funnel, so that urine can flow to the ureter

Ureter
The inner part of the kidney is called the renal pelvis which leads to the ureter
The renal pelvis is continuous with the ureter.
