BACKGROUND

Nocturia is the most frequently reported lower urinary tract symptom, but the impact of medical and surgical treatments on this symptom remains poorly evaluated. The objective of this work was to carry out a systematic review of the literature on the medical and surgical management of nocturia in men with bladder outlet obstruction due to benign prostatic hyperplasia.

METHODS

A systematic review of the literature was conducted including the effects of medical and surgical treatments on nocturia. Articles were selected by 3 independent reviewers before being analyzed and synthesized.

RESULTS

Among medical treatments, the most effective on nocturia seems to be desmopressin. Nevertheless, prescribing restrictions to men under 65 years of age hinder its use in routine practice. The effect of other medical treatments remains modest, although significant compared to placebo groups. The decrease in the number of nocturia would decrease from 0.25 to 0.7 in placebo group and from 0.29 to 1.1 in active treatment groups (alpha blocker, diuretic, anti-inflammatory, IPDE-5, 5 alpha reductase inhibitor). Surgical treatments seem to be more effective on nocturia. Although persistent in half of the patients undergoing surgery, the number of nocturia episodes decreased in 70% of them.

CONCLUSIONS

Nocturia is one of the most common urinary symptoms and the one that responds the least to the proposed medical and surgical treatments. The information given to patients by urologists must emphasize the modest effects to be expected in this area.
