Abstract: Objectives. To examine the variability of bladder outlet obstruction and mild lower urinary tract symptoms in patients with benign prostatic hyperplasia (BPH) followed up by watchful waiting. Methods. The International Prostate Symptom Score (IPSS) has four questions related to voiding symptoms and three related to filling symptoms. Scores of 0 to 7, 8 to 19, and 20 to 35 represent mild, moderate, and severe symptoms, respectively. Over a period of 36 months the IPSS questionnaire was administered to 479 patients 50 to 81 years old (mean age 63) with BPH. A pressure-flow study was used to determine the presence of bladder outlet obstruction. On the basis of their scores, the patients were classified into 50 with mild, 227 with moderate, and 202 with severe symptoms. In the present study only patients with a mild score were analyzed. Results. Of 50 patients with mild symptoms, 16 (32%) had bladder outlet obstruction. After a period of 9 to 22 months (mean 17) of watchful waiting, these 16 patients were reviewed. Twelve (75%) of the 16 had bladder outlet obstruction reconfirmed by pressure-flow studies, and 3 (18.8%) of 16 had increased symptoms (moderate symptomatic) and underwent treatment (1 began pharmacologic treatment, and 2 chose transurethral resection). A total of 4 (25%) of 16 patients still had mild voiding disturbances and refused the second urodynamic evaluation. The remaining 34 patients with no obstruction had annual routine follow-up and had persistent mild symptom scores and normal uroflowmetric results. These patients did not undergo another pressure-flow evaluation. Conclusions. A pressure-flow study is routinely avoided in patients with a mild IPSS. From symptoms alone it was not possible to diagnose bladder outlet obstruction in these patients. Pressure-flow studies and symptom profiles measure different aspects of the clinical condition. After a mean follow-up of 17 months of watchful waiting, 13 (81.2%) of 16 patients were clinically stable. Because the need for therapy is dictated by quality of life, it is difficult to propose treatment for patients with minimal symptoms, even in the presence of bladder outlet obstruction.
