Jump to content. The prevalence of kidney stones is increasing significantly in the United States. At Michigan Medicine, our Endourology, Kidney Stone and Lithotriptor Program has a history of outstanding clinical care, innovation and research. As a comprehensive stone program we provide patient services across the entire spectrum of care — working closely with endocrinologists, nephrologists and radiologists to offer the best care possible to you. Our urologists are experts in diagnostic evaluation, surgical therapies, metabolic studies and nonsurgical care, and treat approximately stone patients a year.
The prevalence of urolithiasis has been observed to increase during last decades. Kidney stones over 2 cm in diameter are the common urologic problem. European and American Associations of Urology has published guidelines on Urolithiasis and presented the most effective tools to treat large stones. On the other hand many experienced endourologic centres choose other modalities from their armamentarium. All treatment methods are characterized by their efficacy and safety which are usually inversely proportional. It is crucial for patients and physicians to find a golden mean.

Percutaneous nephrolithotomy PCNL is a minimally invasive procedure considered as the treatment of choice for the management of large-scale and fully-formed kidney stones. New surgical tools such as dilatation of the nephrostomy tract with mechanical dilatation contribute to the reduction of these risks, together with an improvement in the operative times and a lower rate of complications. At present there are multiple scales measuring the lithiasic morphology Guy, the STONE nephrolitometry score system and the nomogram of the Office of Clinical Investigation of the Endourology Society - CROES which allow to evaluate the degree of complexity of the stone, the possibility of residual stones and the risk of complications. These tools allow us to do a better analysis of the risk factors of the patient who will be taken to this type of endoscopic procedure in order to decrease morbidity and complication rates. The use of pneumatic dilators during percutaneous nephrolithotomy reduces the rates of intraoperative and postoperative complications, which would have an impact on hospitalization times and surgical success for the management of renal stone. Recent technological and surgical advances have reduced the need for open surgery with less invasive procedures, such as percutaneous nephrolithotomy PCNL , extracorporeal shock wave lithotripsy SWL and retrograde ureteroscopy.
Men are affected twice as often as women, and most frequent stone formers have their first stone in their twenties. Kidney stones are more common during hot weather, but can occur at any time of the year. A kidney stone is a collection of mineral salts and protein that collect to form a solid crystalline mass. They can start as tiny stones that pass in the urine unnoticed, or they may grow to a size that cannot be passed and may cause symptoms such as pain, nausea, vomiting, or recurrent urinary tract infections. Most kidney stones are composed of calcium-containing crystals, but in total there are more than 10 types of stones that can form in the urine. If a stone grows large enough it can get caught in the kidney or the ureter the tube that drains the kidney into the bladder.
Percutaneous Nephrolithotomy for Treatment of Kidney Stones Greater Than 2 cm
These procedures are treatments for kidney stones that are used in patients with large or irregularly shaped kidney stones, people with infections, stones that have not been broken up enough by SWL extracorporeal shock wave lithotripsy or those who are not candidates for another common stone treatment, ureteroscopy. Stones that are bigger than 2 cm the size of a marble require this procedure. Both procedures involve entering the kidney through a small incision in the back. Once the surgeon gets to the kidney, a nephroscope a miniature fiberoptic camera and other small instruments are threaded in through the hole. The surgeon can see the stone, use high frequency sound waves to break up the stone, and "vacuum" up the dust using a suction machine. This requires a general anesthesia. You will need a short 2 or 3 day hospitalization.
The stones include small passed stones up to large staghorn stones. Stone composition or type is indicated when available.,
Sudden, intense pain is the hallmark of a kidney stone. See pictures of different types, the causes, symptoms, and treatments in this WebMD slideshow.
