Abstract

Objective: In this study, biochemical and histopathological changes in renal functions were investigated to evaluate the effects of experimentally induced intra-abdominal hypertension. Material and Methods: Thirty male Wistar albino rats were used in this experimental study. Rats were divided into four groups. Group 1 (control group, n=6) were only anesthetized. After the anesthesia, a 20 G intracatheter was introduced intraperitoneally to Group 2 (sham group, n=8), Group 3 (n=8) and Group 4 (n=8). Intra-abdominal pressure applicati- on was not performed in Group 2. We applied 20 mmHg intra-peritoneal pressure to Group 3 and 30 mmHg to Group 4 for 3 hours. After withdrawing 3 mL intracardiac blood from all groups, the kidneys were removed for histopathological examination. Serum urea and creatinine levels were measured in all groups. Results: In the biochemical examination, blood urea and creatinine levels were statistically different among all groups (p<0.05). Serum creatinine levels in group 3 and serum urea and creatinine levels in group 4 were significantly increa- sed. In the histopathological examination, the kidneys in Group 1 and Group 2 were evaluated as normal. In Group 3, congested areas were detected in the glomeruli and interstitial regions. In addition to these findings seen in Group 3, dilatations were detected in the pelvicaliceal structures and proximal ureters in Group 4. Conclusion: When intra-abdominal pressure is increased, the levels of serum urea and creatinine are increased, beca- use the kidneys were damaged. Foci of hemorrhage in interstitial area, dilatations in the proximal ureter, renal pelvis, and lymphatics were the pathologic findings seen in the kidneys.

Özet

Amaç: Bu çalışmada deneysel olarak oluşturulan intraabdominal hipertansiyonun böbrek fonksiyonları üzerine biyokimyasal ve histopatolojik değişikliklerinin birlikte değerlendirilmesi amaçlandı. Gereç ve Yöntemler: Bu deneysel çalışmaya Wistar Albino cinsi 30 adet erkek rat dahil edildi. Grup 1’e (kontrol grubu, n=6) sadece anestezi verildi. Anestezi sonrası Grup 2’ye (sham grubu, n=8), Grup 3’e (n=8), Grup 4’e (n=8) intraperitoneal olarak 20 G intraket yerleştirildi. Grup 2’de intraabdominal basınç arttırılmadı. Üç saat süreyle Grup 3’e 20 mmHg intraperitoneal basınç, Grup 4’e 30 mmHg intraperitoneal basınç uygulandı. İşlemler sonrası tüm gruplardan intrakardiyak 3 mL kan alındı. Serumda üre ve kreatinin düzeyleri ölçüldü. Böbrekler total olarak çıkar- tılarak histopatolojik inceleme yapıldı.Bulgular: Biyokimyasal incelemede gruplar üre ve kreatinin düzeyleri açısından karşılaştırıldığında anlamlı farklar saptandı (p<0,05). Grup 3’ün kreatinin düzeyleri ile Grup 4’ün üre ve kreatinin düzeyleri belirgin olarak artmıştı. Histopatolojik incelemede; Grup 1 ve Grup 2’den alınan böbrek spesimenleri normal olarak değerlendirildi. Grup 3’te spesimenlerde glomerüler ve interstisyel alanda konjesyone alanlar saptandı. Grup 4’te bu bulgulara ek olarak pelvikalisiyel yapılarda ve proksimal üreterde dilatasyon saptandı. Sonuç: İntraabdominal basınç arttıkça serum üre ve kreatinin değerlerinin arttığı görüldü. Aynı zamanda böbrek- lerde interstisyel alanda kanama odakları, proksimal üreterde, renal pelviste ve lenfatiklerde dilatasyon gözlendi.
