Journal Title: Dicle Tıp Dergisi - Year 2013, Vol 40, Issue 3
Abstract
The aim of this study is to investigate the relation between hydronephrosis grade and preoperative, peroperative and postoperative data and to evaluate the clinical significance of hydronephrosis in percutaneous nephrolithotomy (PNL). Methods: One hundred and thirty-two patients who had undergone PNL operation by same surgeon between February 2009 and February 2013 were reviewed retrospectively. Patients’ characteristics, preoperative kidney status, operative data were investigated. Grade 1, 2 hydronephrosis were determined as Group I, Grade 3, 4 hydronephrosis were determined as Group II. Preoperative, peroperative and postoperative property differences between groups were compared statistically. For the multivariate analysis, logistic regression analysis was used to determine independent predictors of hydronephrosis. Results: Patients mean age was 46.2±13.7 years (8-73). Operation mean time was 101(10-250) minutes. 56 and 76 patients’ data were analyzed in Group I and Group II, respectively. There was no difference in age, gender, BMI, and surgeon experience between groups. Dropping stone history in same kidney (p=0.012), stone diameter (p=0.022), the number of calyceal stones (p=0.005), presence stone in the other kidney (p=0.027), renal parenchymal thickness (p=0.026) and operation time (p=0.011) had significantly in univariate analysis. In logistic regression model, dropping stone history in the same kidney, the number of calyceal stones, presence stone in the other kidney and operation time had a relationship with hydronephrosis. Conclusion: In PNL, patients with low-grade hydronephrosis might have decreased complication rates due to diminished operation time, which resulted in reduced number of calyceal stones and stone size. Key words: Percutaneous nephrolithotomy, PNL, hydronephrosis, outcome
