Possibility of Post Percutaneous Nephrolithotomy Renal Function Alterations leading to Acute Kidney Injury

Introduction: Percutaneous nephrolithotomy has obtained the mainstay role as a procedure of gold standard in patients harboring renal lithiasis larger than ۲ cm. It has earned an outstanding reputation as a low complications/low mortality minimally- invasive procedure worldwide. Therefore, its complications carry a great deal, and considering bleeding as its main problem, possible post-bleeding Acute Renal Injury must be checked out.Methods: This is a cross-sectional study planned for ۹۱ patients who underwent PCNL. The renal Function variable had been tuned primarily as Serum Creatinine levels, which had been obtained before surgery following afterwards sessions as the order of days ۱, ۲, and ۳۰ after surgery.Results: Demographic data were as Gender: ۶۳(۶۹.۲%) males. The mean age of the patients was ۴۷.۸± ۴.۷ years. Analytic Data as Mean stone size was ۲۵ mm, Serum sodium & potassium & hemoglobin & hematocrit level &GFR. Data analysis uttered the considerable rise in the creatinine levels on the second day (p value<۰.۰۵), although respecting its levels after ۱ month, all recovered in one month and meant no considerable decline neither in GFR or other biochemical levels. Conclusion: Our Data revealed a considerable decrease in the overall kidney function through an increase in the serum creatinine and electrolytes levels on the second postoperative day which was shown to be completely recovered based on their measured levels after one month.
