Clinical Analysis Of Relative Factors In Predicting The Degree Of Recovery Of Renal Funtion Among Postoperative Patients Of Upper Urinary Tract Calculi

Objective:To explore the factors related to affect the recovery ability of renal function among postoperative patients of upper urinary tract calculi, evaluate the value of relative factors in predicting the recovery of renal function, to provide important information for clinical diagnosis and treatment.Methods:Make a retrospective analysis of clinical data of renal insufficiency causing by obstruction among 138 cases of upper urinary tract calculi patients,including 52 cases of renal calculi and 86 cases of ureteral calculi. Make a systematic analysis and summary on the factors which have possible effect on the recovery of postoperative renal function (GFR) by univariate analysis, Pearson analysis,and multivariate Logistic regression analysis.Results:Univariate analysis showed that gender, body mass index, and operative methods have no relationship with recovery of renal function (P> 0.05).And those factors including age, time of obstruction, renal parenchyma thickness, preoperative renal function, renal artery resistance index, renal pelvis urine PH, anteroposterior diameter of pyelic separation, whether a solitary kidney, and whether complicated with urinary tract infection,are related to recovery of renal function (P< 0.05). Logistic regression analysis showed that the relative factors including age, renal parenchyma thickness, whether a solitary kidney,and renal pelvis urine PH,can be used as an independent and more prominent influence factor to judge renal function recoverability (P<0.05).Conclusion:Those factors including age, duration of obstruction, thickness of renal parenchyma, preoperative renal function, renal artery resistance index, pH of renal pelvis urine, anteroposterior diameter of pyelic separation, whether a solitary kidney, and whether complicated with urinary tract infection,all can be related to predicting the degree of recovery of renal function of postoperative patients of upper urinary tract calculi.
