We assessed the prevalence of pelvic pain in a general urology population presenting for evaluation of unrelated non-painful complaints. Specific focus was placed on assessing for clinical predictors of pelvic pain. Materials &Methods: This is an IRB-approved prospective, cross-sectional survey- based study of female patients presenting to a general urology clinic over a 10-month period (7/2018-5/2019). Patients presenting specifically for a painful complaint were excluded (i.e. flank pain, interstitial cystitis). Patients completed a 32-item survey with questions pertaining to demographics, comorbidities and pelvic pain characteristics. Chart reviewwas performed. Comparison tests (chi-squared, fisher’s exact) and stepwise multivariable logistic modeling were performed for analysis. Results: A total of 181 women completed the survey, with a mean age of 56 years. Presenting chief complaint varied (Table 1). Overall, 75 (41%) women reported pelvic pain. Those with pelvic pain were younger compared to those without (52 vs 59 years, p=0.001), but there were no differences in chief complaint, race, education, income, or activity level (p>0.05). Univariable logistic regression analysis identified BMI, depression, fibromyalgia, overactive bladder, and any bowel symptoms as possible positive predictors of pelvic pain (Table 2). Final best-fit multivariable model found overactive bladder, fibromyalgia, and presence of bowel symptoms as independent positive predictors of pelvic pain. Conclusions: Female pelvic pain is prevalent in a general urology population. Our study identified significant associations with overactive bladder, fibromyalgia, and bowel symptoms. Further research is needed to better understand the etiologies of pelvic pain and the possible relationship with identified clinical predictors. Investigating Fluid Intake in an Underserved Community: What Factors are Associated with Low Urine Volume on 24-hour Urine Collections A. Nourian 1 ; E. Ghiraldi 1 ; M. Chen 1 ; J. Friedlander 1,2 1 Albert Einstein Medical Center, Philadelphia, PA, USA; 2 Fox Chase Cancer Center, Philadelphia, PA, USA Introduction: Stone prevention is dependent on high fluid intake, with evidence that low urine volume (LUV) can promote nephrolithiasis in the absence of other metabolic abnormalities. Herein, we investigate patient-related factors associated with LUV on initial 24-hour urine collection in an underserved population. Materials & Methods: A retrospective review was performed of patients treated for nephrolithiasis at our institution fromAugust 2014-January 2019. Patients who submitted 24-hour urine samples were divided into two groups based on whether their initial collection was greater than two liters or not. Factors associated with 24-hour urine volume were analyzed using bivariate andmultivariate analyses.As a secondary outcome, we investigated factors associated with corrected 24-hour urine volume on repeat 24-hour urine collection. Results: 45.1% (208/461) submitted 24-hour urine collections. 63.9% (133/208) of these patients had a LUV on the initial collection. LUV was more common in females (77.1% vs. 49.5%; p = 0.001), and patients with no insurance and Medicaid (no insurance (100%) vs. Medicaid (74.1%) vs. Medicare/private (58.6%); p = 0.02). Female gender and insurance status were independent predictors of LUV on multivariable analysis. 39.5% (17/43) of patients with LUV who provided a subsequent collection were able to correct their urine volume. Patients who successfully improved their LUV were older (58.5 vs. 45.9 years, p = 0.0149), and more likely to have undergone surgery (94.1% vs. 53.8%, p = 0.006). In our multivariable analysis, undergoing surgery was associated with correcting urine volume. Conclusions: Female patients and those with no insurance or Medicaid were more likely to have LUV on an initial 24-hour urine collection. Further research into barriers to fluid intake is important for these two groups, along with directed patient education on strategies for increasing fluid intake. MP3-08 28
