FIELD: medicine.
SUBSTANCE: method involves carrying out urological examination for determining hydrodynamic resistance of ureter calculated from formula Z=8
L
μ/(π
R4), where Z is the hydrodynamic resistance of ureter, L is the ureter length, R is the ureter radius, μ is the urine viscosity. Angle α at which the ureter enters the urinary bladder is determined from formula cosα = 8
l1
μ/(Z
π
R4), where l1 is the perpendicular drawn from the upper edge of the ureter to the its exit projection line, μ is the urine viscosity, Z is the hydrodynamic resistance of ureter, R is the ureter radius. Vesicoureteral reflux recidivation is predicted when the angle of α+90° is less than 120°.
EFFECT: enhanced effectiveness in reducing the number of recidivation cases.
