AB  - OBJECTIVES: To evaluate the lower urinary tract symptoms, classified by the 
      International Prostate Symptom Score (IPSS), urodynamic results (Watts Factor 
      (WF), Bladder Contractility Index (BCI), and post void residual (PVR), in order 
      to differentiate Detrusor Underactivity (DU) from Bladder Outlet Obstruction 
      (BOO). METHODS: Retrospective observational study performed from 2011 to 2018 at 
      the Hospital das Clinicas of Unicamp. Two phases were done: first, to estimate 
      sample size, and second, to evaluate the predicted parameters. Male patients with 
      range age from 40 to 80 years were included. Patients were divided into two 
      groups: Group 1, without BOO and with DU; Group 2, with BOO. Variables analyzed: 
      age, comorbidities, symptoms, urodynamic data (BCI and WF) and PVR. RESULTS: 
      Twenty-two patients were included in each group, with medians of 68 (Group 1) and 
      67.5 years old (Group 2) (p = 0.8416). There was no difference for comorbidities. 
      In relation to IPSS, medians were: 16.5 and 20.5, respectively (p = 0.858). As 
      for symptoms, there was predominance of combination of storage and voiding 
      symptoms in the two groups (p = 0.1810). Regarding PVR, 15 patients in Group 1 
      and 16 in Group 2 presented PVR> 30mL (p = 0.7411). BCI presented median values 
      of 75 and 755.50 for Group 1 and Group 2, respectively (p < 0.0001), while WF had 
      medians of 22.42 and 73.85 (p < 0.0001). CONCLUSION: Isolated symptoms, 
      classified by IPSS and PVR, could not differentiate patients with DU from those 
      with BOO, but it was possible using urodynamic data.
