This document lists signs and symptoms of potential prostate problems, including difficulty urinating, frequent urges to urinate especially at night, pain in the lower abdomen or behind the scrotum, blood or pus while urinating, and impotence. It notes that without treatment, these problems could lead to tumor formation. It also provides advice that if unable to urinate at all, one should try doing so seated in a tub of cool or lukewarm water, and if still unable, a catheter may be needed after consulting a physician.
