Objective To analyse the level of agreement amongResults For the 18 patients, the urologists, as a first choice, treated a mean (sd, range) of 8.3 (3.4, 3-16) urologists from the industrialized world in the management of men with lower urinary tract symptoms patients with TURP, 3.9 (3.6, 0-11) with alphablockers, 2.3 (1.7, 0-6) with watchful waiting and (LUTS). Methods Thirty-three urological departments partici-1.7 (2.4, 0-9) with finasteride. The other therapy options were only oÂered as a first choice by a few of pated in the study. A computer program was used to provide an unbiased format of 18 simulated the urologists in a few of the cases. The mean (sd, range) cost per patient of the diagnostic process was cases of men with LUTS which individual urologists then evaluated diagnostically and made therapeutic US$ 594 (209, 326-1350). Conclusion There was considerable disagreement among decisions about their management. The management of the patients was assessed for the probability that a the urologists about the management of men with LUTS, which included both the choice of diagnostic diagnostic test was used, that a therapy was oÂered to a particular patient, the first-choice therapies selectests and the criteria for oÂering therapy to patients. If such disagreement prevails generally, it may be ted, the mean cost and range for the diagnostic process per patient and the number of first-choice therapies detrimental for the outcome of patients seeking medical attention for LUTS, and the cost of the medical oÂered by one urologist for all the patients. Various discriminators for these therapeutic decisions were care of these patients will be unnecessarily high.
