In order to evaluate the ability of transurethral prostatie balloon dilatation (TUPBD) to effectively treat prostatic obstruction, 18 men (aged 53–77 years) with obstructive small prostate glands were evaluated with symptom scores and urodynamic studies before and 6 and 12 months after TUPBD utilizing the endoscopically placed Advanced Surgical Intervention 75F balloon. After TUPBD, 81% of men reported some improvement in their symptoms with statistical significance (P <.05) at 6 and 12 months after the procedure. The mean non‐invasive peak flow rate did not change significantly after TUPBD. Although the mean maximum voiding pressure (Pv max) and the maximum detrusor pressure at peak flow (Pq max) were reduced at 6 and 12 months postoperatively, the changes were found to be statistically insignificant (P >.05). In addition, the use of Abrams and Griffiths pressure‐flow nomogram revealed a “non‐obstructive” pressure‐flow study in only one patient at 6 and 12 after TUPBD. Although TUPBD results in some symptomatic improvement, on pressure‐flow analysis the majority of men remain obstructed at 6 and 12 months after the procedure.
