METHOD OF PREDICTING TERMS OF RECOVERING FUNCTION OF KIDNEYS IN PATIENTS WITH HYDRONEPHROSIS Russian patent published in 2012 - IPC A61B10/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to urology, and can be used for predicting terms of recovering function of kidneys in patients with hydronephrosis in case of urinary tract obstruction. Clinical examination is carried out and risk factors are determined: causes and degree of hydronephrosis, presence of post-operative complications, duration of hydronephrosis disease, effective kidney plasma flow, parenchimatose index and time of maximal rise of renohistogram curve. Determined risk factors are given gradations and numerical values, after which terms of recovering function of kidneys in months (Y) is calculated by formula: Y=8.83-4.56X₁+3.18X₂+3.64X₃+14.01X₄+0.01X₅-0.32X₆+0.19X₇ where X_1,2,7 are gradations and numerical values of risk factors, X₁ are causes of hydronephrosis: cervical cancer - 1, stenosis of pelvic-ureteral segment - 2, nephroptosis - 3; X₂ is hydronephrosis degree: II -2, III - 3; X₃ is post-operative complications: no - 0, yes - 1; X₄ is duration of hydronephrosis duration: to 3 years - 0, from 3 to 5 years - 1, more than 5 years - 2; X₅ is effective kidney plasma flow after operation, ml/min; X₆ is parenchimatous index after operation, units; X₇ is time of maximal rise of renohistogram curve after operation, min.

EFFECT: method provides possibility to predict expected term of recovering function of kidneys in months in patients with hydronephrosis
