OBJECTIVES: This study was designed to compare urodynamic types of bladder outlet obstruction (BOO) and histological architecture of the prostate in patients with benign prostatic hyperplasia (BPH).
PATIENTS AND METHODS: Twenty-four patients with symptomatic BPH, who underwent transurethral resection of the prostate (TURP), were included in the study. Before surgery, a pressure-flow (P-F) study was performed in all patients. According to the classification by Spanberg et al., they were divided into 5 normal type, 6 low-compliant, 6 compressive and 7 constrictive obstruction. The area density and total area of smooth muscle, fibrous tissue, glandular epithelium and glandular lumen in BPH specimens were estimated using morphometric analysis.
RESULTS: In all groups, the stromal component occupied about three fourths of BPH specimens, and fibrous tissue was the most prominent element. However, neither area density nor total volume of each histological component showed a significant difference among the four groups.
CONCLUSION: The type of BOO in patients with BPH cannot be explained by histological architecture alone.
