OBJECTIVES: To investigate whether coexistence of high-grade prostatic intraepithelial neoplasia (HPIN) should change our therapeutic approach to infravesical obstruction. MATERIAL AND METHODS: Of 505 patients who underwent sextant transrectal ultrasonography (TRUS)-guided prostate biopsy, 65 (12.8%) had HPIN and 29 of them underwent prostatectomy (23 transurethral resection of prostate (TURP), 6 open) due to obstructive urinary symptoms. Patients without carcinoma were followed up with semiannual prostate-specific antigen (PSA) and digital rectal examination. After a follow-up of 24.8 +/- 11.0 months, 19 of 29 patients who accepted our call had another sextant biopsy. RESULTS: Mean age and initial mean PSA values of 29 patients were 67.6 +/- 6.7 years and 9.26 +/- 5.91 ng/ml, respectively. The final pathological evaluation of the surgical specimens revealed 2 prostatic adenocarcinomas both in the TURP group. The remaining 27 (93.2%) patients were found to have benign prostatic hyperpl
