Abstract

Böbrek ve drenaj sisteminin embryogenezisi konjenital anomalinin gelişmi ve sıklığından sorumludur. Renal damarların yapısını incelemek için Madras Medical College, Chennai anatomi bölümünden 50 çift yetişkin insan böbreği elde ettik. Elli çift üzerinden; bir sağ böbrek örneğinde üreter duplikasyonu gözlemledik fakat aynı çiftin sol böbreği normaldir. Üreterin unilateral duplikasyonu renal pelvisten, daha sonra tek bir üreter olarak devam eden ve mesaneye katılan duplike üreterin her iki pelvik ağızın yakınındaki pelvik ağıza kadar genişler. Üreterin kısmi duplikasyonunun insidansı 100 böbrek üzerinden 1'dir. Aynı zamanda anteriyor yerine posteriyor olarak giden duplike üreteri kesen, aorttan inferior anormal arter olarak oluşan, inferior segmental arteri de gözlemledik. Çalışmamız ameliyatı planlamadan önce duplike üreter ile ilişkili vasküler varyasyonlar hakkında klinisyenlere önden bilgi vermektedir

Abstract

Purpose: The embryogenesis of the kidney and drainage system accounts for the development and frequency of congenital abnormalities. Material and Methods: We collected 50 pairs of adult human kidneys to study the renal angioarchitecture from department of anatomy Madras Medical College, Chennai. Results: Out of 50 pairs in one specimen of right kidney we observed duplication of ureter but the left kidney of same pair is normal. The unilateral duplication of ureter extend s from renal pelvis to pelvic brim near the pelvic brim both the duplicated ureter joined later continue as single ureter and entering the urinary bladder. The incidence of partial duplication of ureter is 1% out of 100 kidneys. We also observed inferior segmental artery arising from the aorta as inferior aberrant artery which crosses the duplicated ureter posteriorly instead of going anteriorly. Conclusion: Our study gives primary knowledge to the clinicians about the vascular variations associated with duplication ureter before planning a surgery.
