The invention disclosed herein provides a system and method for diagnosing lower urinary system conditions by receiving urodynamic data and subjective symptomatic impressions concerning a patient. The system and method then assigns weighted point values to the urodynamic data, for example, urethal pressure profiles due to sphincter contraction conditions such as urgency (2) and stress incontinence (4), and the subjective symptomatic impressions, quantifies norms for lower urinary system function, as a whole or in part, and quantifies recognized pathologies of lower urinary system conditions as degrees of departure from the norms. The system and method then determines a lower urinary system condition diagnosis of the patient, as a function of the degrees of departure from the norms, by invoking a set of rules to compare the weighted point values assigned and the quantified norms. The invention then reports the lower urinary system condition diagnosis, treatment recommendation, or further diagnostic suggestions.
