Abstract

Introduction: Studies reporting percutaneous nephrolithotomy (PNL) outcomes in relation to stone burden are very limited in the literature. We therefore examined our data to analyze our stone-free rates and complication rates of PNL with regards to stone surface area. Materials and Methods: Data of 234 patients who underwent 234 PNL procedures were retrospectively analyzed. Patients were stratified with respect to stone burden into two groups. Groups were compared with respect to the success of therapy, complications, requirement of secondary procedures, number of tracts, drop in hematocrit level and blood transfusion requirement in relation to stone burden. Results: The overall stone-free rate for PNL was 78.6% with a complication rate of 34.6%. Stone-free rates decreased with increasing stone burden (p=0.001). The total number of complications rose with increasing stone surface area (p=0.0001). The mean operative time increased with increasing stone burden (p<0.05). The need of multiple tracts also increased with increasing stone burden (p<0.05). Conclusion: There is a decrease in the overall stone-free rate as well as an increase in the complication rate, the secondary procedure rate, the mean operative time and the need of multiple tracts with increasing stone surface area with PNL.

Özet

Yayınlarda artan taş yükünün perkütan nefrolitotomi (PNL) tedavisinin başarısı ve istenmeyen yan etki oranlarına etkisini inceleyen çalışma sayısı oldukça azdır. Bu çalışmamızda, artan taş boyutunun PNL tedavisindeki başarı ve istenmeyen yan etki oranları üzerine olan etkisini inceledik. Retrospektif olarak 234 hastanın (234 PNL işlemi) verileri incelendi. Hastalar taş boyutuna göre iki gruba ayrıldı. Gruplar, taş boyutuna göre, tedavi başarısı, istenmeyen yan etki oranları, ek tedavi gereksinimleri, trakt sayısı, hematokrit düzeyindeki düşüş ve kan transfüzyonu gereksinimi açısından karşılaştırıldı. PNL için son taşsızlık oranı %87.1 ve istenmeyen yan etki oranı ise %34.6 olarak belirlendi. Artan taş boyutu ile taşsızlık oranları azalırken (p=0.001), istenmeyen yan etki oranlarının arttığı (p=0.0001) görüldü. Ortalama ameliyat süresi (p<0.05) ve multipl trakt gereksiniminin (p<0.05) artan taş boyutuna bağlı olarak arttığı izlendi. Artan taş boyutuna bağlı olarak PNL tedavisinde taşsızlık oranları azalmakta, istenmeyen yan etki oranları, ek tedavi gereksinimi, ortalama ameliyat süresi ve çoklu trakt gereksinimi ise artmaktadır.
