Özet
Background and aims: Percutaneous nephrolithotomy is the preferred technique for treating large kidney stones. One of the most frequent complications after percutaneous nephrolithotomy is renal bleeding, which requires blood transfusion. The aim of the present study was to determine the risk factors associated with blood transfusion following percutaneous nephrolithotomy. Methods: In order to determine the risks factors associated with blood transfusion, we retrospectively reviewed the medical records of 341 patients that underwent percutaneous nephrolithotomy in our clinic between 2011 to 2016. Patients were categorized into two groups: those that did not received blood transfusion and those that received blood transfusion. The groups were compared in terms of age, sex, body mass index, comorbidity, presence of anatomical abnormalities, history of anticoagulant use, history of urinary tract infection treated at the preoperative period, history of previous renal surgery, history of extracorporeal shock wave lithotripsy, Hounsfield unit value of the stone, degree of hydronephrosis, stone localization, stone opacity, stone size, solitary kidney, puncture site, operation time, thickness of parenchyma, and preoperative hematocrit values. Results: Transfusion group had significantly lower degree of hydronephrosis, lower preoperative hematocrit values, bigger stones, greater parenchymal thickness and longer operation time than non-transfusion group (p < 0.001). Furthermore, transfusion group had significantly higher median Hounsfield unit value than non-transfusion group (p < 0.001). Conclusions: It is important to establish risk factors associated with renal bleeding to take necessary precautions like the preparation of sufficient blood product for patients who are likely to have bleeding during the perioperative period of percutaneous nephrolithotomy.
