Abstract

Introduction: This study is an evaluation of the surgical, oncological, and functional outcomes of our first 103 laparoscopic partial nephrectomy experiences.Methods: A total of 103 patients who underwent laparoscopic partial nephrectomy between 2008 and 2016 were identified retrospectively. Demographic data, perioperative renal function, radiological and pathological features of the tumors were recorded.Results: The mean patient age was 54.72 years (range: 19-71 years) and the mean tumor diameter was 32.42 mm (range: 12-82 mm). The mean preoperative creatinine value was 0.78 mg/dL (range: 0.4-1.7 mg/dL), postoperative first day creatinine value was 1.04 mg/dL (range: 0.5-2.48 mg/dL), and creatinine value at postoperative first month was 0.89 mg/dL (range: 0.4-1.8 mg/dL). There was no statistical significance between preoperative and postoperative functional parameters.Pathological study revealed 6 (5.82%) oncocytomas, 12 (11.65%) angiomyolipomas, and 85 (82.52%) renal cell carcinomas. Of the 85 renal cell carcinomas, 62 (60.19%) were clear cell, 14 (13.59%) were papillary, and 9 (8.73%) were chromophobe subtype. Mean follow-up was 46 months (range: 6-92 months). There was no local recurrence or metastasis during followup, including patients with positive surgical margin. Cancer-specific survival was 100%, and overall survival was 96.2%, with 4 non-cancer-related deaths.Discussion and Conclusion: Although it has a challenging learning curve, laparoscopic partial nephrectomy has impressive results with respect to patient comfort and similar oncological outcomes to radical neprectomy.

Özet

Giriş ve Amaç: Kliniğimizde böbrek tümörü nedeniyle laparoskopik parsiyel nefrektomi yapılan ilk 103 hastanın cerrahi, onkolojik ve uzun dönem fonksiyonel sonuçlarının değerlendirilmesi amaçlandı.Yöntem ve Gereçler: Kliniğimizde 2008-2016 tarihleri arasında laparoskopik parsiyel nefrektomi yapılan toplam 103 hasta çalışmaya dahil edildi. Demografik veriler, perioperatif renal fonksiyonlar, tümörün patolojik ve radyolojik özellikleri retrospektif olarak değerlendirildi.Bulgular: Yaşları ortalama 54-72 yıl olan 68 erkek, 35 kadın toplam 103 hastaya transperitoneal laparoskopik parsiyel nefrektomi uygulandı. Ortalama tümör çapı 32.42 mm (12-82 mm) olarak hesaplandı. Tümörlerin 4'ü (%3.88) bilateral, 45'i (%43.68) sağ ve 54'ü (%52.42) sol böbrek yerleşimli idi. Yine tümörlerin 32'si (%31.06) üst pol, 41'i (%39.80) alt pol ve 30'u (%29.12) orta zon yerleşimliydi. Hastaların 2002 TNM sınıflamasına göre; 64'ü (%62.13) T1a, 32'si (%31.06) T1b ve 7'si (%6.79) T2a klinik evre ile prezente oldu. Hastaların preoperatif ortalama kreatinin değerleri 0.78 mg/dl (0.41.7), postoperatif ilk gün ortalama kreatinin değerleri 1.04 mg/dl (0.5-2.48) ve postoperatif 1. ayda ortalama kreatinin değerleri 0.89 mg/dl (0.4-1.8) olarak hesaplandı. Hastaların preoperatif ve postoperatif 1. aydaki kreatinin değerleri arasında istatistiksel anlamlı fark görülmedi (p>0.05). Patolojik inceleme sonucunda lezyonların 6'sı (%5.82) onkositom, 12'si (%11.65) anjiyomiyolipom ve 85'i (%82.52) renal hücreli karsinom olarak raporlandı. Renal hücreli karsinomların 62'si (60.19) berrak hücreli karsinom, 14'ü (%13.59) papiller karsinom ve 9'u (%8.73) kromofob karsinom olarak saptandı. Fuhrman sınıflamasında 18'i (%17.47) grade 1, 75'i (%72.81) grade 2 ve 10'u (%9.70) grade 3 olarak rapor edildi. Hastalar ortalama 46 ay takip edildi. Takiplerinde cerrahi sınır pozitif olanlar dahil hiçbirinde radyolojik olarak lokal nüks ve metastaz saptanmadı. Dört hastada kanser dışı ölüm görülen çalışmada, hastalığa özgü sağkalım oranı %100 ve genel sağ kalım oranı %96.22 olarak tespit edildi.Tartışma ve Sonuç: Açık ve laparoskopik parsiyel nefrektominin onkolojik sonuçlarının benzer olması ve laparoskopinin hastaya sağladığı avantajlar nedeniyle, her ne kadar öğrenme eğrisi uzun olsa da laparoskopik teknik ile deneyimli ellerde çok başarılı sonuçlar elde edilebilmekte ve gün geçtikçe uygulanma oranı artmaktadır.
