Study Notes
- The development of the kidney passes through three phases: Pronephros, Mesonephros, and Metanephros, with each stage having specific characteristics and functions.
- The ureter originates from the renal pelvis, crosses the external iliac arteries, and lies on the anterior surface of the psoas major muscle.
- Different congenital abnormalities of the kidney include renal agenesis (resulting from the failure of kidney development), pelvic kidney (caused by a failure of kidney ascent), and horseshoe kidney (fusion of both kidneys at their lower ends).
- Anomalies of the ureter can include ureteral agenesis (failure of ureteric bud development) and duplication of the ureter, which can manifest as bifid ureter (partial duplication) or double ureters (complete duplication).
- The adult urinary bladder, when empty, is positioned in the lesser pelvis, partially superior and posterior to the pubic bones.
