Doppler Ultrasonographic Evaluation of Renal Blood Flow in Cirrhotic Patients

Abstract

Objectives: Cirrhotic patients often have various hemodynamic changes in systemic, splanchnic and renal circulation. In our study we aimed to investigate the renal vascular resistance indices of cirrhotic patients by Doppler ultrasonography. Material and Methods: Fifty nine cirrhotic patients and 45 healthy controls were enrolled in this study. Renal vascular resistance indices (RI) of right and left kidney were measured by Doppler ultrasonography. The control group and the cirrhotic patients had similar renal function test results. The cirrhotic patients were classified according to the Child-Pugh scoring. Results: When cirrhotic patients were compared to the control group, although there were no differences in renal size and parenchymal thickness, there were significant differences in renal arterial RI (right kidney; 0,70±0,06 vs 0,61±0,03 and left kidney; 0,69±0,06 vs 0,61±0,03) and interlobar arterial RI (right kidney 0,65±0,06 vs 0,57±0,04 and left kidney 0,66±0,06 vs 0,56±0,03)(p

Sirozlu Hastalarda Renal Kan Akımının Doppler Ultrasonografi ile Değerlendirilmesi

Öz

Amaç: Karaciğer sirozlu hastalarda sıklıkla sistemik, splanknik ve renal dolaşımda çeşitli hemodinamik değişiklikler mevcuttur. Bu hemodinamik değişiklikler özellikle ileri evre sirozu olan hastalarda daha belirgin olmaktadır. Biz çalışmamızda sirozlu hastalarda renal kan akımını araştırmayı amaçladık. Materyal ve Metod:Çalışmaya 59 karaciğer sirozlu hasta ve 45 sağlıklı kontrol alındı. Tüm hastaların ve kontrol grubunun her iki böbrek boyutları ve parankim kalınlıkları ölçüldü. Renal vasküler rezistans indeksleri (Rİ) sağ ve sol böbrekten doppler ultrasonografi ile değerlendirildi. Bulgular: Sirotik hastalar ile kontrol grubu karşılaştırıldığında, sırası ile her iki böbrek boyutlarında ve parankim kalınlığında fark yok iken, her iki böbrekten ölçülen renal arter (sağ böbrekten 0,70±0,06 karşılık 0,61±0,03 ve sol böbrekten 0,69±0,06 karşılık 0,61±0,03) ve interlober arter Rİ (sağ böbrekten 0,65±0,06 karşılık 0,57±0,04 ve sol böbrekten 0,66±0,06 karşılık 0,56±0,03) arasında anlamlı fark vardı (p
