Kidney stones do not usually cause elevated prostate antigen. Prostate-specific antigen, a marker for prostate cancer, is organ-specific and generally elevated due to prostate disease. Prostatic hyperplasia and prostatitis can lead to mild elevations, while prostate cancer is usually seen as a significant elevation. Kidney stones do not usually affect the prostate, and therefore, they do not usually cause elevated prostate antigen. When kidney stones do not lead to infection or hydronephrosis, there is usually no obvious discomfort. When complicated by infection or hydronephrosis, there can be obvious back pain, and the infection is obvious, there can be fever, discomfort, and some patients may have symptoms such as frequent urination, urgency, painful urination, and hematuria. Kidney stones can usually be found by ultrasound or CT examination. To summarize, if the examination found that the prostate antigen is elevated, please go to the regular hospital for diagnosis and treatment.
