N2 - Transurethral balloon dilatation of the prostate has been shown to be a safe and potentially effective alternative to surgery in the treatment of benign prostatic hyperplasia, with a 66% success rate in relatively unselected patients. This study hypothesized that more careful patient selection might result in a significantly better rate of improvement. Ninety-one subjects with symptoms and signs of prostatism attributable to benign prostatic hyperplasia were studied. Group 1 comprised 42 patients with an initial mean symptom score of 16.8, residual urine of 249 ml, maximal flow rate of 7.9 ml/sec, and nomogram of maximal flow rate of -1.5. Group 2 comprised 49 less symptomatic patients with an initial mean symptom score of 14.5, residual urine of 105 ml, maximal flow rate of 10.7 ml/sec, and nomogram of maximal flow rate of -0.8. The difference in mean age and prostatesize between groups was not statistically significant, but differences in baseline symptom score, residual urine, maximal flow rate, and nomogram of maximal flow rate were significant (p <.04). Transurethral balloon dilatation of the prostate was performed under local anesthesia or IV sedation and analgesia with single or double-balloon catheters with maximal diameters of 25-30 mm inflated to 2.5-4.0 atmospheres pressure for 10 min. Patients were followed up with repeat symptom scoring, uroflometry, and measurement of residual urine. After a mean follow-up of 22 months (range, 6-48 months), an improvement in symptom score was seen in 80% of group 2 patients compared with 43% in group 1. Improvement in symptom scores was statistically significant in both groups (p <.04). We conclude that transurethral balloon dilatation of the prostate is more effective in patients with more moderate symptoms and with less marked signs of obstruction than in patients with more marked prostatism.
