If your kidney has been very damaged by stones, it may need to be removed. The surgeon will make a larger incision in your abdomen or side and remove the stones from your kidney. If PNL and SWL aren’t options, your doctor might recommend that you have open surgery to remove the stones. If your stones are very large or you have a lot of them, you might need to have this procedure more than once. After this treatment, the pieces of stone will pass through your urinary tract and come out in your urine. SWL uses intense shock waves directed from a machine outside your body to break up the stones into tiny pieces. You may have to stay in the hospital for a couple of days afterward. Then the stone is removed through the incision. The surgeon makes a small incision in your back and inserts a scope and several small instruments. PNL is the preferred treatment for people with stones that are too large to be broken up by SWL. Doctors treat these stones with shock wave lithotripsy (SWL) or percutaneous nephrolithotomy (PNL). It’s important to treat struvite stones because if they grow large enough, they can damage your kidney and lead to life-threatening infections. This test uses X-rays and a special dye to look for problems with your kidneys, ureters, and bladder. A powerful magnetic field and radio waves make detailed pictures of your urinary tract. This test takes X-ray images from many different angles to produce detailed pictures of your urinary tract. Radiation creates a picture of your kidneys and other organs in your urinary tract. Then a laboratory checks the culture for stone-forming substances like calcium, oxalate, and uric acid. For this test, you collect all of your urine in a 24-hour period. The doctor might perform a culture on that sample to see if your urine contains bacteria. A urinalysis checks a sample of your urine to diagnose a urinary tract infection. Your doctor might collect a blood sample to check levels of waste products like calcium and uric acid that can form into stones. Open surgical removal is the best option for treatment of complete staghorn calculi.Your doctor will do one or more of the following tests to help diagnose the cause of your symptoms, and find out if you have struvite stones: Avoid nephrectomy in patients with bilateral disease. Injury to the kidneys is caused by obstruction, local infection, and infection of the renal parenchyma.Ī nephrectomy is indicated for the patient with a unilateral stone whose renogram shows very poor function. The stones grow rapidly and fill in, or make an internal cast of, the renal collecting system. The patient usually does not complain of pain, but loin ache may be present. In this setting, recurrent pyelonephritis is common. The bacteria are found within the interstices of the stone crystals therefore, the infection is very difficult to eradicate, and the rate of recurrence is high. The infective organism produces the enzyme urease, which splits urea to form ammonium ions, thus rendering the urine alkaline. These stones are caused by the action of bacteria the culprit may be Proteus, Klebsiella, Enterobacter, or Pseudomonas species. A ureteral catheter (pigtail) had been placed in the pelvis of the left kidney to facilitate drainage.ĭrs Demetrios Papaioannides, Aphrodite Vlachopanou, Demetrios Cyrochristos, and Christos Tatsis of Arta, Greece, write that the calculi were triple-phosphate stones-composed of calcium, ammonium, and magnesium phosphate. The patient had a history of recurrent urinary tract infections caused by Proteus mirabilis. A roentgenogram of the kidneys, ureter, and bladder of a 58-year-old man shows bilateral stones in the renal pelvis and the renal calyces.
