Objectives:
The aim of the present study was to investigate the correlation between lower urinary tract symptoms (LUTS) and severity of depressive symptoms in patients treated for depression.

Methods:
102 patients (43 males, 59 females) aged 20–67 (M = 46.1) treated for depression were included in this cross-sectional analysis. Depressive symptoms were assessed with the 17-item Hamilton Depression Rating Scale (HDRS) and Quick Inventory of Depressive Symptomatology – Self Report (QIDS-SR). LUTS were examined with the International Prostate Symptom Score (IPSS). In order to analyze the impact of presented symptoms, both urological and psychiatric, on quality of life of analyzed individuals the 30-item General Health Questionnaire (GHQ-30) was used.

Results:
The average IPSS score in women was significantly higher than in men (9.59 vs. 6; p = 0.04). Patients suffering from at least moderate depression assessed with QIDS-SR had significantly higher scores in IPSS (9.76 vs. 4.1; p = 0.002). Severity of all LUTS assessed with IPSS correlated with QIDS-SR score in examined men (p < 0.05). In women, the total IPSS score correlated with the QIDS-SR score (p < 0.05) and with the total GHQ-30 score (p < 0.05). Anumber of other significant (p < 0.05) correlations were observed between the total IPSS score and certain items’ scores in the GHQ-30 both in men and women.

Conclusions:
LUTS are common among patients with depression. There is a correlation between severity of depressive symptoms and LUTS. LUTS affect quality of life and well-being as well as cause marked distress in depressed patients. Comorbidity of LUTS and depression should draw attention of both psychiatrists and urologists and enhance interdisciplinary treatment approach. Further prospective and cohort studies are essential to reveal more details of the correlation between LUTS and depression.
