The results of prostatectomy: a symptomatic and urodynamic analysis of 152 patients.

There were 152 patients with prostatism investigated by inflow cystometry and pressure flow analysis of micturition before and after elective prostatectomy. Many symptoms attributed to obstruction were found to be owing to bladder instability, which was demonstrated in 60 per cent of the patients. The symptomatic improvement postoperatively was accompanied by a decrease in the incidence of instability to 25 per cent. The repeat urodynamic studies and symptom analysis demonstrated a surgical success rate of 88 per cent.
