Abstract

Objective: Overweight and obesity increased worldwide over four decades. In 2016, nearly 11% of men and 15% of women over 18 years old were obese. Obesity is accepted as a risk factor for renal stones. The relationship between obesity and urolithiasis is complicated. Various complications can occur during perioperative or postoperative follow-up in obese patients. Minimal invasive nature and high efficacy of Retrograde Intrarenal Surgery (RIRS) present itself as a safe and less morbid treatment option. In this study, we aimed to compare the efficacy and safety of RIRS in the treatment of kidney stones in different BMI levels.

Material and Methods: Files of 552 patients who underwent RIRS for renal stones between January 2012 and December 2017 were reviewed. We classified patients according to the World Health Organisation classification. These three groups were compared for stone-free rate, complication rate, operative and fluoroscopy times and length of hospital stay.

Results: The stone-free rate (SFR) of the study population was 80.8%. It was 81% for Group 1, 83.7% for Group 2 and 77.7% for Group 3. There was no statistically significant difference between the three groups among SFR (p=0.346). Clinical insignificant residual fragments (CIRF) status was also similar among three groups (p=0.254). Complication rates between the three groups were statistically similar (p=0.416).

Conclusion: In this study, we have shown that RIRS is a suitable option for all urolithiasis patients even for obese individuals. Stone-free rates, length of hospital stay, operation time and complication rates in obese patients are similar with non-obese patients.

Abstract

Amaç: Obezite, son kırk yılda dünya çapında artış göstermiştir. 2016'da, 18 yaşın üzerindeki erkeklerin yaklaşık % 11'i ve kadınların% 15'i obezdi. Obezite böbrek taşları için bir risk faktörü olarak kabul edilmektedir. Obezite ve ürolitiyazis arasındaki ilişki karmaşıktır. Obez hastalarda perioperatif veya postoperatif takipte çeşitli komplikasyonlar ortaya çıkabilir. Retrograd Intrarenal Cerrahi (RIRS), minimal invaziv yapısı ve yüksek etkinliği nedeniyle obez hastalar için güvenli ve daha az morbid bir tedavi seçeneği olarak kendini göstermektedir. Bu çalışmada, farklı Vücut Kitle İndeksi (VKİ) seviyelerindeki böbrek taşlarının tedavisinde RIRS prosedürünün etkililiğini ve güvenliğini karşılaştırmayı amaçladık.

Gereç ve Yöntemler: Ocak 2012 - Aralık 2017 tarihleri arasında böbrek taşı nedeniyle RIRS yapılan 552 hastanın dosyaları incelendi. Dünya Sağlık Örgütü sınıflandırmasına göre normal kilolu hastalar Grup 1, fazla kilolu hastalar Grup 2 ve obez hastalar Grup 3 olarak sınıflandırıldı. Bu üç grup taşsızlık oranı, komplikasyon oranı, ameliyat ve floroskopi süreleri ve hastanede kalış süreleri açısından karşılaştırıldı.

Bulgular: Çalışma popülasyonunun taşsızlık oranı (SFR) % 80,8 idi. Grup 1 için % 81, Grup 2 için % 83,7 ve Grup 3 için % 77,7 idi. Üç grup arasında SFR arasında istatistiksel olarak anlamlı fark yoktu (p = 0,366). Klinik önemsiz rezidüel fragman (CIRF) saptanan hasta sayısı da üç grup arasında benzerdi (p = 0.254 ). Üç grup arasındaki komplikasyon oranları istatistiksel olarak benzerdi (p = 0,416).

Sonuç: Bu çalışmada obez bireyler de dahil olmak üzere RIRS’nin tüm ürolitiyazis hastaları için uygun bir seçenek olduğunu gösterdik. Obez hastalarda taşsızlık oranları, hastanede kalış süreleri, ameliyat süreleri ve komplikasyon oranları obez olmayan hastalarla benzerdir.
