Mastering the Duplex Collecting System Kidney: Pathophysiology, Diagnosis, and Management
Introduction to the Duplex Collecting System Kidney (DCSK) The Duplex Collecting System Kidney (DCSK) , often simply referred to as a Duplex Kidney or Duplex Collecting System , represents the most common congenital anomaly of the upper urinary tract. This condition is characterized by a kidney that is drained by two ureters instead of the typical single ureter. While some individuals with this anomaly may remain asymptomatic throughout their lives , others can face significant urological complications, making a thorough understanding of its pathophysiology, clinical presentation, and imaging features essential for medical professionals. 🔬 Pathophysiology and Embryology The embryological origin of the DCSK lies in an abnormal budding or division of the ureteral bud . The ureteral bud typically arises from the distal portion of the mesonephric duct and grows towards the metanephros to form the renal pelvis and the ureter. Classification of Duplex Systems Duplex...
