Summary— Forty‐eight men with urodynamically proven bladder outflow tract obstruction (BOO) and 19 with retention secondary to benign prostatic hypertrophy were treated by balloon dilatation of the prostate as out‐patients; 31 were dilated with 20 mm and 36 with 25 mm balloons. Of the 48 men with BOO, 37 had repeat cystometrograms at intervals ranging from 3 to 11 months after dilatation and 33 (89%) remained obstructed by urodynamic criteria. Of 6 who only had a peak flow rate assessment, 5 had a flow < 12 ml/s. Of the 19 patients in retention only 3 were able to void and all are obstructed. Symptoms of hesitancy, poor stream, frequency and nocturia were improved in less than 50% of patients. No reliable correlation was found between objective response and balloon size, length of time of dilatation, prostate size or morphology, detrusor pressure or stability, or post‐dilatation urethrogram appearances. Balloon dilatation to 25 mm is not adequate therapy for bladder outflow tract obstruction or urinary retention from prostatic hypertrophy.
