Alternatives

In the treatment of ureter stones, extracorporeal shock wave lithotripsy (ESWL) has been most widely performed and has become the preferred treatment for this condition. ESWL is a new technique that offers an alternative to surgery for patients...

with kidney or ureter stones. ESWL works by pulverizing the stones into sand-like particles that can be excreted with little or no pain. This is achieved by the ESWL procedure approximately 90% of the time. The shock waves are a form of high-energy pressure that can travel in air or water. When generated outside the body, they pass through the tissues of the body without damaging them, but can destroy a stone inside a kidney or urethra. The shock waves pass through both without injury. A stone has a greater density and, when the shock wave hits it, the waves scatter and break it up.

Type 2 diabetes, when poorly controlled, can directly damage several organs and tissues like the kidney, the retina of the eye, and the nerves. Type 2 diabetes also leads to increased risk of heart disease and arterial disease and makes it harder for wounds to heal (delays healing).

A nephrostomy is an artificial opening created between the kidney and the skin which allows for the drainage of urine directly from the upper part of the urinary system (renal pelvis).

Nephrostomies are created by surgeons or interventional radiologists and typically consist of a catheter which pierces the skin and rests in the urinary tract. It is performed under ultrasound guidance or under image intensifier. Local anesthetic infiltration is used to numb the area where the needle would pass through to make the puncture on the kidney.

Urine is collected in an external bag which can be emptied as often as necessary.
