[A clinical classification of severity of benign prostatic hyperplasia].
The grading of severity of benign prostatic hyperplasia (BPH) was attempted by scoring clinical manifestations associated with the disease. The total score (0 to 100 points) is the sum total of subjective and objective one, each of which is 50 points at its maximum. Subjective score is composed of symptom score (0 to 25 points) evaluating 5 each obstructive and irritative symptoms and quality of life (QOL) score (0 to 25 points). Objective score consists of functional and anatomical scores. Functional score (0 to 25 points) is calculated by scoring maximum flow rate and residual urine. Anatomical score (0 to 25 points) is calculated by the score of prostatic volume. Seventy-seven BPH patients have been evaluated by this scoring system. The mean values of 4 kinds of scores (symptom, QOL, functional and anatomical scores) were about 8-9 points and thus comparable each other. The total score was 35.4 +/- 12.3 in the average and divided into 6 grades: Grade 0; < 10, Grade 1; > or = 10, Grade 2; > or = 20, Grade 3; > or = 30, Grade 4; > or = 40, Grade 5; > or = 50. The present scoring and grading systems appear to be appropriately formulated to estimate the global severity of BPH patients. Further studies to apply the system to evaluation of therapeutic responses would be mandatory to examine its validity.
