A renal ultrasound revealed a kidney stone (diameter: 11 mm) in the lower right calyx (Figure 1 A ). Twenty-one days after the ESWL, the athlete's kidneys were examined with a second renal ultrasound confirming the absence of the kidney stone (Figure 1 B ). Fourteen months after ending his CMS cycle, the third renal ultrasound showed no new kidney stone formations (Figure 1 C ).
