• Summary Aims:  To investigate the diagnostic value of the International Prostate Symptom Score (IPSS) voiding‐to‐storage subscore ratio (IPSS‐V/S) in male lower urinary tract symptoms (LUTS). Methods:  A total of 253 men with LUTS were enrolled from January 2005 to July 2010. The voiding (IPSS‐V) and storage IPSS (IPSS‐S) subscores were recorded separately by the patients themselves. The IPSS‐V/S was calculated and compared among various aetiologies based on videourodynamic studies. Receiver operating characteristics (ROC) curves were constructed for comparing the diagnostic value of various non‐invasive methods for predicting failure to voiding and storage lower urinary tract dysfunction (LUTD). Results:  Patients with failure to voiding LUTD, including benign prostatic obstruction (n = 72), bladder neck dysfunction (n = 19), urethral stricture (n = 3) and poor relaxation of the urethral sphincter (n = 32), had mean IPSS‐V/S scores > 1. In contrast, patients who were urodynamically normal (n = 2) or had failure to storage LUTD, including idiopathic detrusor overactivity (n = 84), increased bladder sensation (n = 37), and detrusor overactivity and impaired contractility (n = 4), had IPSS‐V/S scores ≤ 1. When IPSS‐V/S was used to differentiate male LUTS, failure to voiding LUTD was found in 81.2% of patients with IPSS scores > 1, while failure to storage LUTD was found in 75.7% of patients with IPSS‐V/S ≤ 1. The area under ROC curve of IPSS‐V/S was higher than for other non‐invasive methods for predicting failure to voiding and storage LUTD. Conclusion:  Measuring IPSS subscores and calculating IPSS‐V/S is a simple and useful method to differentiate failure to voiding and failure to storage LUTD in men with LUTS. IPSS‐V/S may provide a guide for the initial treatment, especially for primary care physicians without access to urological studies. Linked Comment: Chapple. Int J Clin Pract 2011; 65: 519.
