Materials and Methods: The patients who underwent a complete urological evaluation for MH were identified retrospectively. The risk factors for urinary malignancy which defined in the 2020 American Urological Association/Society of Urodynamics, Female Pelvic Medicine & Urogenital Reconstruction guidelines were recorded for each patient. Multivariable logistic regression was performed to establish a predictive risk-scoring system. The odds ratios obtained as a result of the logistic regression analysis were scored. Results: A total of 1461 patients who had undergone a complete urological evaluation for MH were identified. The urinary malignancy rate was 3.4% (50 of the 1461 patients). According to the odds ratios, age >40 was calculated as 1 point; male gender, 2 points; smoking history, 4 points; presence of occupational risk factor, 1 point; and presence of macroscopic hematuria, 2 points. For the cut-off risk score, 5 points was found to be the most appropriate score according to the sensitivity and specificity levels. The patients with risk scores of 5 points or lower were considered to be in the low-risk group for urinary tract malignancy. Conclusion: The patients with a risk score of 5 points or above require complete urological evaluation. The results of the present study may reduce the number of patients undergoing unnecessary urological evaluation.
