[The importance and significance of post-micturitional bladder residue in the evaluation of prostatism].
The presence of a significant post-voiding residue is often considered to be secondary to bladder neck obstruction and frequently constitutes the main indication for transurethral resection of the prostate. In order to validate this approach, the files of 350 patients presenting with symptoms of prostatism and assessed by urodynamic studies were analysed retrospectively. The results of the study demonstrated that, regardless of the value of the residue, approximately 30% of patients were not obstructed despite a high post-voiding residue (PVR), while approximately 70% of patients with minimal or no PVR were considered to be obstructed on the basis of urodynamic criteria. These results therefore demonstrate that the presence of a post-voiding residue is not indicative of bladder neck, but reflects a lesion of the detrusor. Considered alone, it therefore should not constitute an indication for transurethral resection of the prostate.
