title: The Relationship between Acidic Urinary pH and Overactive Bladder; Alkalization of Urine Improves the Symptoms of Overactive Bladder.
abstract: BACKGROUND
  To determine association between urine pH and OAB symptoms and to determine if urinary alkalization improves overactive bladder (OAB) symptoms.
  
  
  METHODS
  659 patients with OAB were enrolled in this study between June 2012 and May 2014. 329 patients (group 1) were included in the final analysis. 201 adults were used as a control group (group 2). 24-hour urinary pH and the validated Turkish version of the OAB-V8 questionnaire were performed in patients. A 24-hour urine pH <6.2 was considered acidic urine. In the second part, a diet program was performed for 4 weeks in 30 participants. Urine pH values and OAB-V8 scoring results were recorded before the diet program and 2 and 4 weeks after the diet program.
  
  
  RESULTS
  Acidic urinary pH was determined in 61.4% of patients with OAB. There was a significant association between the presence of acidic urine and OAB. Also, the OAB-V8 scores of patients were significantly higher in patients with acidic urine than nonacidic urine. OAB-V8 scores of patients showed statistically significant improvement after diet therapy (17.87 ± 6.52 vs. 10.43 ± 7.17; p < 0.001).
  
  
  CONCLUSIONS
  We found that acidic urinary pH was closely associated with OAB, and alkalization of urine improved lower urinary tract symptoms. We suggest that urinary pH should be considered as a parameter in treatment planning of patients with OAB.
