METHOD FOR DIAGNOSING INFRAVESICAL OBSTRUCTION CASES Russian patent published in 2007 - IPC A61B5/20 

FIELD: medicine.

SUBSTANCE: method involves carrying out uroflowmetric patient examination and the results are used for determining mean urination rate, urinary excretion time, time required for reaching maximum urination rate. Infravesical obstruction index is determined as IVO _uroflow = 2,286-0.086xQ_aver+0.03xT_flow - 0.049xT_Qmax, where Q_aver is the mean urination rate in ml/s; T_flow is the urinary excretion time in s; T_Qmax is the time required for reaching maximum urination rate in s. Infravesical obstruction index value being less than 2.1, no infravesical obstruction is diagnosed to be available. The value being from 2.1 to 2.5, moderate degree of infravesical obstruction is considered to be the cases. The value being greater than 2.5, marked infravesical obstruction is considered to be the case.

EFFECT: high accuracy of diagnosis.
