[Q]: Question: Is race a predictor of prostate cancer detection on repeat prostate biopsy?
Answer: Race is not a predictor of prostate cancer detection in men undergoing repeat prostate biopsies. With the exception of HGPIN, all other clinical parameters were similar between black and white men. Serum PSA, PSA velocity, HGPIN and ASAP were found to be significant predictors of subsequent prostate cancer detection.
[A]: no


[Q]: Question: Do treatment of Renal Stones ≥20 mm with Extracorporeal Shock Wave Lithotripsy?
Answer: For renal stones with a surface area ≤400 mm2 and a radiodensity equal to or less than that of the 12th rib as determined by a KUB film, ESWL may be considered the first line of treatment, even for stones with a diameter ≥20 mm. For large stones requiring repeat treatments, the surface area of the residual stones after the first ESWL is a predictor of the final treatment result.
[A]: yes
