Objective: To determine the correlation of TGF-b1 and estrogen with prostate volume in BPH patients, old patients without BPH and young patients. Materials and methods: We enrolled 30 patients and allocated them into three groups. First group consists of BPH patients, second group consists of old male patients with more than 55 years of age, and third group consists of young male patients with less than 40 years of age. We analyzed the level of TGF-b1 and estrogen in these patients. Transrectal USG was used to measure the prostate volume. We analyzed the correlations of TGF-b1 and estrogen level with prostate volume. Results: We found a positive strong correlation between estrogen and prostate volume in the BPH patient group (p=0,021; r coeff=0,786). Other group showed no significant correlations. Conclusion: Estrogen plays an important role in BPH pathophysiology. Further research on the influence of estrogen in BPH patients is recommended.

Objective: The aim of this study was to compare the epithelial cell counts in each lobe of prostate glands with benign prostatic hyperplasia (BPH). Material and methods: Twenty-two BPH patients who underwent transurethral resection of the prostate (TURP) in Diponegoro Dua Satu Surgery Hospital Klaten, from May until November 2006 were enrolled in this study. Tissue from each lobe of the prostate gland was separately collected, from the middle (A), left lateral (B), right lateral lobes (C). All samples were fixed in 10% formalin buffer, embedded in paraffin and sectioned in 4 micrometer slices with microtome. After hematoxylin eosin (HE) staining, number of epithelial cells was counted under light microscopy. Difference in epithelial cell counts in each alveolus between the three lobes was statistically analyzed using t-test (p
