[Clinico-flowmetric analysis of patients being surgically treated for BPH]

Benign prostatic hypertrophy (BPH) is a common urological disease with a standard surgical approach, transurethral resection (TUR) or open adenectomy (OA), but the flowmetric clinical results are controversial. Fifty-five patients were evaluated; in 23 of them TUR was performed and 32 underwent OA. The Boyarsky clinical questionnaire was filled in, and a flow evaluation conducted prior and subsequent to the procedure to measure maximum and average flow (Qmax and Qave) which was correlated to mictional volume according to Siroky's nomogram. The purpose is to compare the flowmetric clinical results of TUR and OA, and to evaluate flowmetry as a prognostic factor. Correlation of obstructive symptoms and Qmax is low (r = 0.49) and minor for irritative symptoms. Both groups of patients achieve significant clinical improvement (p < 0.001). OA obtains a 248% increase in Qmax, while this figure is 76% with TUR. Patients with post-treatment obstruction after OA are 9.3%, and 26.9% for TUR. Results are better when Qmax prior to surgery is < 5 ml/s than when it is > 10 ml/s.
