title: Hip dysfunction-related urinary incontinence: a prospective analysis of 189 female patients undergoing total hip arthroplasty.
abstract: Patients reporting that their symptoms of urinary incontinence have decreased after total hip arthroplasty can be encountered in orthopedic practice. In this questionnaire-based study, we prospectively evaluated the symptoms of urinary incontinence before and after total hip arthroplasty. The International Consultation on Incontinence Questionnaire-Short Form was used to prospectively evaluate these symptoms in 189 consecutive female patients undergoing total hip arthroplasty. The patients were asked to fill in a questionnaire before and 3 months after surgery. A decrease in the International Consultation on Incontinence Questionnaire-Short Form score of ≥1 point was defined as an improvement, whereas an increase of ≥1 point was defined as worsening. A total of 81 (43%) patients reported urinary incontinence before total hip arthroplasty. At 3 months after surgery, symptoms of urinary incontinence were improved in 64% of these patients, remained unchanged in 32% and worsened in 4%. Mean International Consultation on Incontinence Questionnaire-Short Form score in patients with urinary incontinence before surgery significantly improved from 6.0 to 3.5 (P = 0.0002). These findings suggest a relationship between hip joint function and pelvic floor function, and consequently a hip dysfunction-related urinary incontinence.
