Abstract

Postoperative urinary retention necessitating catheterization after major lower limb arthroplasty surgery adds to the patients’ postoperative discomfort and increases the risk of urinary tract infection with potential risk of transient bacteraemia and seeding of infection to prosthetic joints. Preoperative evaluation of patients with lower urinary tract symptoms may help to identify at-risk patients and the International Prostate Symptoms Score (IPSS) has been used as a screening tool to quantify the severity of symptoms in males. A prospective cohort of 303 patients undergoing total hip or knee arthroplasty was evaluated using the IPSS. Patients were categorized into three symptom groups (mild, moderate and severe based on scores of 0–7, 8–18 and greater than 18, respectively) and four age groups (<50 years, 51–60 years, 61–70 years and greater than 70 years). Twenty-six patients (8.6%) developed urinary retention and were catheterized postoperatively; of these, 16 were male and 10 were female. Statistical analysis using logistic regression models showed significant association between severe IPSS scores (>18) and urinary retention requiring catheterization in both males and females with both high specificity and sensitivity in the test in predicting postoperative catheterization. Hence, this test is a valid preoperative screen in predicting postoperative catheterization.
