Abstract

INTRODUCTION AND HYPOTHESIS:

In this study, we planned to explore the effects of sodium bicarbonate orally (NaHCO3) treatment on female patients with lower urinary tract symptoms (LUTS) who have acidic urine pH values (<6).

METHODS:

NaHCO3 was given orally to 33 female patients for 4 weeks at a dose of 2 × 4 g/day. Laboratory values, bladder diary, the Patient Perception of Bladder Condition Score (PPBC), Patient Perception of Intensity of Urgency Scale (PPIUS), Overactive Bladder-Validated 8-question Awareness tool (OAB-V8), Pelvic Pain and Urgency & Frequency Patient Symptom Scale tests (PUFSS), and the King's Health Questionnaire (KHQ) scores before and after treatment were compared.

RESULTS:

A significant increase was detected in urine pH values measured after treatment (5.31 ± 0.52 to 7.2 ± 0.66, p < 0.001), but not in blood pH values (7.369 ± 0.33 to 7.384 ± 0.28, p = 0.14). After treatment, a significant decrease was detected in daily frequency, nocturia, urgency, and urge incontinence prevalence (p < 0.001,p = 0.003, p < 0.001, p = 0.002, respectively) and PPBC, PPIUS, PUFSS, and OAB-V8 symptom scores (p = 0.004, p = 0.002, p < 0.001, p < 0.001, respectively). A significant decrease was detected in all KHQ subunit scores.

CONCLUSION:

Urine alkalinization with NaHCO3 orally in female patients with LUTS and acidic urine pH has a significant level of positive effects on symptoms and symptom scores. Our results show that this new treatment modality-which is inexpensive, easy to use, and has a low side-effect profile is effective in this chronic patient group.
