In 379 men less than age 75 years who underwent initial transurethral prostatectomy for benign prostatic hypertrophy specimen weights were compared with host ages, obesity, smoking habits and the presence of incidental cancer. Among 334 men 60 to 74 years old average specimen weights increased with increasing obesity from 20.3 to 36.6 gm. Underweight men in comparison with men at least 30% overweight demonstrated more small specimens (10 gm. or less, 24% versus 2%, p < 0.001) and fewer large specimens (50 gm. or more, 5% versus 26%, p < 0.005). This pattern was present in smokers and nonsmokers. Adenoma weights increased with increasing host age and were larger in nonsmokers of all age groups. Body habitus was similar in the prostatectomy patients and 290 office patients of similar age, suggesting no increase in obstructive uropathy among obese men despite the larger adenomas. These observations are compatible with different risk factors for the obstructing and nonobstructing components of benign prostatic enlargement.
