[Giant prostatic hypertrophy: a case report].

Benign prostate hypertrophy weighing more than 200 g is defined as giant prostatic hypertrophy. An 81-year-old man presented with urinary retention and underwent retropubic prostatectomy. Blood loss was 1,850 ml and he received 800 ml of autologous blood. The removed specimen weighed 267 g and pathology revealed benign hyperplasia of the prostate. We collected 32 such cases from the Japanese literature.
