“…IPSS and AUA scores were considered equivalent and therefore trials using these instruments were combined. The IPSS/AUA symptom questionnaire asks men to rate four voiding symptoms (poor stream, intermittent flow, straining, incomplete emptying) and three storage symptoms (frequency, nocturia, urgency) on a scale from 0 (not present) to 5 (severe) to give a total score ranging from 0 to 35, with symptom severity defined as: mild (0-7), moderate (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19) or severe (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35). With Madsen-Iversen scores, patients are rated in terms of the quality of their urinary stream, straining to void, hesitancy, intermittency, bladder emptying, stress incontinence or post void dribbling, urgency, frequency, and nocturia on a scale from 0 to 4 to give a total score ranging from 0 to 27, with symptom severity defined as: mild (<10), moderate (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) or severe (>20).…”
