OBJECTIVE: To evaluate in patients with mild bladder outlet obstruction (BOO) who refused the proposed treatment and were on watchful waiting (WW), the symptomatic and urodynamic changes after 1-5 years of follow-up.
METHODS: 102 patients with lower urinary tract symptoms (LUTS) and BOO (Schafer class: 2-6, median 3) were clinically and urodinamically re-evaluated after 1-5 years of follow-up. Of these, 82 were submitted to medical (alfuzosin or finasteride) or surgical treatment (prostatectomy or TUIP) and 20, who refused the proposed treatment, were on WW. A retrospective study was made on these 20 patients who underwent a second International Prostatic Symptom Score and pressure-flow evaluation after 1-5 years (median: 22 months) of watchful waiting. Wilcoxon matched-pairs signed-ranks test and Kruskal Wallis as appropriate were used for statistical analysis.
RESULTS: In the group of patients who refused the proposed treatment, no statistically significant differences between the two evaluations were observed for any of the parameters investigated: International Prostatic Symptom Score (15.1 +/- 6.8; 14.7 +/- 7.5); maximum flow (11.5 +/- 4.2; 12.1 +/- 4.3); residual urine (90.2 +/- 154.5; 113.3 +/- 158.4); Schäfer class (2.9 +/- 0.9; 2.8 +/- 1.2); Urethral Resistance Algorithm (37.1 +/- 14.4; 37.3 +/- 16.3); Projected Isometric Pressure (113.7 +/- 26.5; 112.7 +/- 21.8).
CONCLUSIONS: Patients with mild BOO may remain clinically and urodynamically stable for a long time.
