Abstract

Objective: To share our results of robotic assisted partial nephrectomy (RAPN) we performed without using ureteral stent in a single center from Turkey. Material and methods: Medical records of consecutive 45 patients (34 men and 11 women) who underwent RAPN for kidney lesions between March 2011 and December 2014 were retrieved, and evaluated. All the procedures were performed by a transperitoneal approach without using ureteral stent prior to surgery. Renal artery clamping was used in all cases and intraoperative ultrasonography was used in 2 cases. Results: Patients undergoing RAPN had a mean tumor size of 4.42 cm (2–8) and a mean renal nephrometry score of 5.82 . The mean estimated blood loss was 250 mL (150-450 ml) and the mean operative time was 195 minutes . There was no statistical difference between the preoperative and postoperative serum creatinine levels at the first follow-up visit (0.9 vs. 0.95, p=0.087). Surgical margin positivity was not detected in any patient, and the mean surgical margin distance was calculated as 0.4 mm . In only 1 patient disease recurrence was detected at the 21st month of the the follow-up period, and no distant metastases was reported in our patients at a mean follow-up of 10 months (3-36 mos). Our complication rate was 11.1% and according to the Clavien system complications were as; grade 2 (3 patients), grade 3a (1 patient) and grade 3b (1 patient). Conclusion: With appropriately selected patients and adequate surgical experience, RAPN performed without using ureteral stent is a safe and feasible method for localized renal tumors

Özet

Amaç: Türkiye'den tek merkez olarak üreteral stent kullanmadan gerçekleştirdiğimiz robot yardımlı parsiyel nefrektomi sonuçlarımızı paylaşmak.Gereç ve yöntemler: Mart 2011 ve Aralık 2014 tarihleri arasında böbrek kitlesi nedeniyle robot yardımlı parsiyel nefrektomi yapılan 45 ardışık hastanın (34 erkek, 11 kadın) medikal kayıtları çıkarılmış ve değerlendirilmiştir. Bütün işlemler, öncesinde üreteral stent kullanılmadan ve transperitoneal yoldan gerçekleştirildi. Bütün olgularda renal arter klemplendi ve 2 olguda intraoperatif ultrasonografi kullanıldı.Bulgular: Robotik yardımlı parsiyel nefrektomi yapılan hastaların ortalama tümör boyutu 4,42 cm ve ortalama RENAL nefrometri skorları 5,82 olarak hesaplandı. Ortalama kan kaybı 250 mL ve ortalama operasyon süresi 195 dakika olarak ölçüldü. İlk izlem süresi sonunda preoperatif ve postoperatif serum kreatinin seviyeleri arasında istatistiksel anlamlı farklılık saptanmadı (0,9'a karşı 0,95, p=0,087). Hiçbir hastamızda cerrahi sınır pozitifliği saptanmadı ve tümörün cerrahi sınıra uzaklığı ortalama 0,4 mm olarak ölçüldü. Sadece 1 hastamızda postoperatif 21. ayda aynı böbrekte farklı lokalizasyonda yeni kitle saptanmış olup, hiçbir hastamızda ortalama 10 aylık takiplerde (3-36 ay) uzak metastaz saptanmamıştır. Komplikasyon oranımız %11,1 olup, Clavien sınıflamasına göre dağılım; 3 hastada grade 2, 1 hasta da grade 3a ve 1 hastada grade 3b şeklindedir. Sonuç: Uygun seçilmiş hastalarda, yeterli cerrahi deneyimle birlikte üreteral stent kullanılmadan yapılan robotik yardımlı parsiyel nefrektomi, lokalize böbrek tümörleri için güvenli ve uygun bir tedavi metodudur
