Metabolic Conditions Linked to Lower Urinary Tract Symptoms

(HealthDay News) — Metabolic abnormalities such as metabolic syndrome and insulin resistance are associated with lower urinary tract symptoms, according to two studies published in BJU International.

Pourya Pashootan, from Saint-Louis Hospital in Paris, and colleagues examined the correlation between metabolic syndrome and the frequency and severity of lower urinary tract symptoms in a cohort of 4,666 men aged 55 to 100 years. 

The researchers found that 51.5% of the patients had metabolic syndrome and 47% were treated for lower urinary tract symptoms. Metabolic syndrome correlated significantly with treated lower urinary tract symptoms (P<.001) and with the severity of lower urinary tract symptoms (P<.001). 

There was an increase in the risk of being treated for lower urinary tract symptoms with an increasing number of metabolic syndrome components.

Serge Luke, MD, from Dunedin Hospital in New Zealand, and colleagues conducted a prospective study to examine the effects of bariatric surgery on lower urinary tract symptoms in a cohort of 86 patients. 

The researchers found that after surgery there was significant weight loss and reduction of BMI. The overall symptom score was significantly reduced at 6 weeks (P<.001), and this was sustained at 1 year. 

The change in total symptoms score was predicted by total symptoms score at baseline, Homeostasis Model Assessment-insulin resistance (HOMA-IR), preoperative insulin level and change in insulin level postoperatively, but not by weight loss.

"The study confirms the improvement in [lower urinary tract symptoms] after weight loss but there is no correlation between the improvement and the time course or degree of weight loss," Luke and colleagues wrote.

The Pashootan study was supported by Astellas.
