Surgical treatment is the gold standard for Benign Prostatic Hyperplasia (BPH) therapy. At the present diagnostic approach allows better patient selection and treatment assignment. In this work we have studied retrospectively the outcome of 120 BHP patients who underwent trans urethral resection (TURP) and of 145 BPH patients underwent "open" prostatectomy. In all the patients surgical time, prostate weight, indwelling catheter standing, rest in bed, early and late complications were evaluated. Irritative symptoms occurred after TURP in 10% of the cases. The two therapeutical options are not comparable for they technically different. The choice between the two depends on the accurate patient characterization and selection.
