![]() ![]() The aim of the surgery is to remove the narrowed portion of the PUJ and join it to the ureter in to allow for easy drainage of urine down the ureter. ![]() Many individuals with a PUJ obstruction do not realise they have this condition until later in life, when they begin developing symptoms such as pain or develop urinary infections. The standard treatment for pelviureteric junction obstruction is open pyeloplasty. The PUJ is the portion of the collecting system that connects the renal pelvis to the ureter. secondary to other disease processes or previous instrumentation).Ī pyeloplasty is a surgical procedure that is indicated for a pelviureteric junction (PUJ) obstruction. PUJ obstruction is usually congenital, but may also be acquired (i.e. This dilatation of the collecting system is referred to as hydronephrosis. If the join between the part of the kidney that collects urine (renal pelvis) and the ureter is narrow, urine will not drain easily and may back up causing dilatation of the collecting system behind that point and enlargement of the renal pelvis (see picture). Nephrologists also treat patients with kidney disease, but they deal more commonly with patients who have kidney failure and other kidney problems not requiring surgery. These include kidney (renal) cancer, kidney stones, and pelvi-ureteric junction obstruction (PUJ obstruction). Here we will discuss only those commonly treated by urologists. Many different conditions can affect the kidney. Urine is carried from each kidney, through a narrow tube called the ureter, to the bladder where it is stored.Īs well as removing waste products, the kidney performs many vital functions, such as controlling fluid balance (how dilute the blood is), regulating various salts or electrolytes in the bloodstream (eg: sodium, potassium, calcium, magnesium), maintaining the correct acidity of the blood, and regulating blood pressure. They filter the blood to remove waste products, which they excrete into urine. ![]() They sit at the back of the body in the loin, or flank, one on each side, just underneath the ribcage.
