Our Multiple Single-step Access Results in Percutaneous Nephrolithotomy/Perkutan Nefrolitotomide Multipl Single-step Akses Sonuclarimiz

Objective: The aim of this study is to evaluate the success and complication rates of percutaneous nephrolithotomy (PNL) with multiple single step access in patients with staghorn kidney stones. Materials and Methods: A total of 118 patients with staghorn kidney stones, who underwent PNL in our clinic between 2008 and 2015, were included in the study. All patients were examined with non-contrast abdominal computed tomography before the operation. Demographic data of patients, operation details, intra- and postoperative complications and additional interventions were evaluated. Results: The mean age of the patients included in the study was 49.6 years. The mean operative time was 139.4 minutes and the mean fluoroscopy time was 126.9 seconds. Postoperative residual stone was detected in 28% of the patients. Postoperative fever was observed in 19 patients (16.2%), and sepsis developed in 3 (2.5%) of them. Additional postoperative procedures were required in 11 patients (9.3%). No patient was lost due to complications. Operation success and complication rates were compatible with the literature. Conclusion: For staghorn stones, PNL with multiple single step dilatation technique can be used as an effective and safe method in adult patients. Keywords: Percutaneous nephrolitotomy, Single-step dilatation, Multiple access Amac: Bu calismada amacimiz, staghorn tasi olan hastalarda yapilan single-step multipl akses perkutan nefrolitotomi sonuclarimizi degerlendirmektir. Gerec ve Yontem: Klinigimizde, 2008-2015 yillari arasinda staghorn tasi olup PNL yapilan 118 hasta calismaya dahil edildi. Operasyon oncesi tum hastalar kontrastsiz batin bilgisayarli tomografi ile degerlendirildi. Hastalarin demografik verileri, operasyon bilgileri, intra/postoperatif komplikasyonlar ve ek girisim gerekliligi ayrica incelendi. Bulgular: Calismaya katilan hastalarin ortalama yasi 49,6 yildi. Ortalama operasyon zamani 139,4 dakika ve ortalama fluoroskopi suresi 126,9 saniyeydi. Hastalarin %28'inde rezidu tas izlendi. On dokuz hastada (%16,2) postoperatif ates yukseligi, 3 hastada (%2,5) sepsis goruldu. On bir hastada (%9,3) ek girisim gerekliligi oldu. Hicbir hasta komplikasyonlar nedeniyle olmedi. Basari ve komplikasyon oranlarimiz literatur ile uyumluydu. Sonuc: Staghorn tasi olan ve PNL planlanan hastalarda, multipl single-step dilatasyon teknigi guvenle uygulanabilir.
