Segmental testicular infarction: A case report.

The incidence of segmental testicular infarction is extremely low. The condition usually presents with acute scrotal pain and may be confused clinically and radiologically with a testicular tumor or torsion. To the best of our knowledge, only a few cases have been reported in the English literature.

Prostate-specific antigen velocity (PSAV) and PSAV per initial volume (PSAVD) for early detection of prostate cancer in Chinese men.

Aim: To investigate the utility of prostate-specific antigen velocity (PSAV) and PSAV per initial volume (PSAVD) for early detection of prostate cancer (PCa) in Chinese men.

Methods: Between January 2009 and June 2012, a total of 193 men (aged 49-84 years, median 67 years) with at least 2 transrectal ultrasonography (TRUS) procedures and concurrent serum PSA measurements underwent prostate biopsy because of suspicion of PCa. The total group were classified into PCa and non-PCa groups, and the variables of the two groups were compared.
