Sports and the Male Genitourinary System

Abstract

In brief Most injuries to the penis and scrotum in sports result from direct blows and require prompt evaluation. Bicycler's penis is a paresthesia and numbness in the perineum and phallus that resolve spontaneously. A direct blow to the scrotum usually causes a testicular contusion that responds to elevation of the scrotum and bed rest. Athletes wear athletic supporters and plastic cups for scrotal protection. Sexually transmitted diseases-nongonococcal urethritis, condyloma acuminatum, and herpes progenitalis-are common urologic problems in athletes. Patients should use condoms or abstain from sexual activity until the condition resolves.

The effect of exercise intensity on hematuria in healthy male runners

“…Footstrike hemolysis and mechanical muscular trauma can be identi®ed by a marked drop in haptoglobin (Hp) concentration with a subsequent increase in hematuria as the excess hemoglobin (Hb) is lost to the urine (Eichner 1985(Eichner , 1986Harold et al 1991;Miller et al 1988;Milne 1988). Finally, hematuria may occur distal to nephrons where jostling of the bladder as a result of running may cause bleeding due to microscopic lesions in the interior wall (Blacklock 1977;York 1990). In runners, bladder or kidney trauma may be identi®ed by cytoscopic analysis of their urine, although the analysis of urine provides only indirect evidence of bladder or kidney trauma.…”
