Aim: To report the demografics, operative and postoperative outcomes of laparoscopic partial nephrectomy (LPN)

in T1a/T1b stage renal tumors.

Matherials and Methods: In total of 60 patients were evaluated, retrospectively who underwent LPN with a

normal contralateral kidney, between May 2015 and October 2018. Demographics, perioperative and postoperative

outcomes were evaluated and discussed with the literature.

Result: 42 patients were included in the study. The mean age, tumor size and RENAL scores were 60.52 (± 10.51) years,

3.58 (± 1.55) cm and 6.548 (± 1.17), respectively. The duration of warm ischemia time was 26,88 (± 6,27) minutes. The

mean operative time, estimated blood loss, length of hospital stay time were 162.26 (± 38.97) min, 166.79 (± 98.32)

mL and 3.45 (± 0.89) days, respectively. Preoperative and postoperative estimated glomerular filtration rate (eGFR)

were 76.83 (± 18.36) and 71.93 (± 20,12) mL/min/1.73 m2, respectively. eGFR decrease was 4.9 (6.38%) mL/min/1.73

m2 at the 3 months postoperative. The rate of postoperative complications, surgical margin status and eGFR decrease

were similer to literature. The mean follow-up time was 21.02 (± 13.26) months.

Conclusion: Although LPN has long learning curve, it is a safe PN method that can be applied in selected renal

tumor cases with excellent oncological and functional results with acceptable complication rates.

T1a/T1b Evre Renal Tümörlerde Laparoskopik Parsiyel Nefrektomi: Biz Neredeyiz?

Öz

Amaç: T1a / T1b evre böbrek tümörlerinde laparoskopik parsiyel nefrektomi yapılan hastalara ait (LPN) demografik

verileri, perioperatif ve postoperatif sonuçları rapor etmeyi amaçladık.

Gereç ve Yöntem: Retrospektif olarak Mayıs 2015 - Ekim 2018 arasında normal kontralateral böbreği olan ve LPN

yapılan 60 hasta değerlendirildi. Demografik, perioperatif ve postoperatif sonuçlar literatür ile değerlendirildi ve

tartışıldı.

Bulgular: Çalışmaya 42 hasta dahil edildi. Ortalama yaş, tümör boyutu ve RENAL skorları sırasıyla 60.52 (± 10.51),

3.58 (± 1.55) cm ve 6.548 (± 1.17) idi. Sıcak iskemi süresi 26,88 (± 6,27) dakika idi. Ortalama ameliyat süresi, tahmini

kan kaybı, hastanede kalış süresi, 162.26 (± 38.97) dk, 166.79 (± 98.32) mL ve 3.45 (± 0.89) gündü. Preoperatif ve

postoperatif tahmini glomerüler filtrasyon hızı (eGFR) sırasıyla 76.83 (± 18.36) ve 71.93 (± 20,12) mL / dak / 1.73 m2

idi. eGFR azalması ameliyat sonrası 3 ayda 4.9 (% 6.38) mL / dak / 1.73 m2 idi. Postoperatif komplikasyon oranı, cerrahi

sınır durumu ve eGFR azalması literatür ile benzer olarak bulundu. Ortalama takip süresi 21.02 (± 13.26) aydı.

Sonuç: Her ne kadar LPN uzun bir öğrenme eğrisine sahip olsa da, seçilmiş renal tümör vakalarında mükemmel

onkolojik ve fonksiyonel sonuçlarla kabul edilebilir komplikasyon oranları ile uygulanabilen güvenli bir PN yöntemidir.
