Perkutan nefrolitotomi (PNL)'de charlson komorbidite endeksinin clavien komplikasyon skalasi üzerine etkisi

Percutaneous Nephrolithotomy (PNL) has been a recent and popular procedure for the treatment of renal stones. The data about PNL, that is widely applied and having various complications, have been obtained from several medical centers. Therefore, the standardization is required for informing the patients and determining or differentiating the degrees of complications. The Clavien-Dindo Classification used in laparoscopic live‐donor nephrectomy, laparoscopic radical prostatectomy, transurethral trostatectomy and recently in percutaneous nephrolithotomy is widely and frequently used today. Having stressed the vital importance of comorbid conditions, The Charlson's Comorbidity Index has been formed. The impact of physiologic changes in patients based on their ages to the operation complications have been investigated in many studies. In this context by taking the ages of patents into account, we have tried to figure out the impact of comorbid conditions on complications identified after PNL operations in our clinic. In this study, the preoperative comorbidities of 360 patients, who had undergone a PNL procedure at the Department of Urology, Bülent Ecevit University, Faculty of Medicine between June 2002 and June 2012, have been evaluated by the Charlson's Comorbidity Index age-adjusted and their postoperative complications using the Clavien-Dindo Classification System. As a result, we have not observed a significant difference between the ratios of postoperative complications, taking into account the caliceal entry and ASA risk profile. Therefore, we think that the recognized preoperative comorbidities are not risk factors for PNL procedures and operations.
