Abstract

One hundred fifty seven patients with benign prostatic hypertrophy(BPH) under going trans. urethral resection of prostate( TUR - P) entered in this study in order to search for factors predictive of a successful outcome. In the follow-up period of 3 months to 7 years, a strictly successful result was achieved in 122 patients(78% ). On analysis of the success rate, 5 favorable factors and 8 unfavorable factors were noted. A symptomatic large prostatic adenoma proven by IVU, TRUS will imply a higher success rate. On uroflowmetry, obstructive BPH proven by maximal flow rate of less than l0 ml/sec and constrictive obstructive flow pattern can also predict a satisfactory outcome. The unfavorable factors always come from a small adenoma, uncertain irritative symptoms and detrusor underactivity. Patients with more than 2 unfavorable factors should be investigated carefully before surgery. The presence of 2 favorable factors without unfavorable factor will usually predict the best surgical outcome.
