Effect of "High-Dose" SWL (8000 Shocks at 24kV) to One Renal Pole on Bilateral Hemodynamics and Tubular Function
...d in the urine. However, a clinical dose of shock wave
lithotripsy (SWL) to one kidney can damage tissue, impair renal blood flow, and temporarily reduce the tubular function of the kidney. These investigators wanted to test the hypothesis that a high "dose" of shock waves (8000 shocks at 24 kilovolts) ...
COGA Suggests Genetic Loci For P3 Brain Wave Abnormality
