APKPD occurs worldwide affecting about 1 in 500 - 1000 people. Hypertension is the most common manifestation of ADPKD and the major contributor to renal disease progression. A definite diagnosis of ADPKD relies on image testing. Renal ultrasound is commonly used because of its cost effectiveness.展开更多

The slender and narrow kidneys are positioned in the retro peritoneal position up against the ventral aspect of vertebral column and may extend the length from the esophagus-stomach junction to cloaca. The kidney in both sexes is composed of sexual（anterior） and pelvic（posterior） parts. The duct of sexual kidney is a narrow duct which is lying alongside its lateral edge. In the female, it is connected to the ureters and then the duct of defi nitive kidney. Before entering the cloaca, two ureters are joined together and open to the apex of the cloaca. In the male, after entering the sexual kidney, the sperm leave the testis through efferent ducts, then these ducts join together and eventually form Bidder＇s duct. The Bidder＇s duct joins the Bowman＇s capsule of the nephrons in the sexual kidney and the nephrons make collecting ducts which are fi lled with both sperm and urine. After leaving the kidney, all the collecting ducts are connected to the Wolffi an duct. Wolffi an duct joins the ureters（merge from defi nitive kidney） just before entering the cloaca. Based on serial paraffi n sections, nephrons consist of a fi ltration unit, the Malpighian corpuscle, and a renal tubule, which can be divided into 4 morphologically distinct segments： proximal tubule（first and second segment）, distal tubule, and collecting tubule. Collecting tubules merge and form a branch system that opens into collecting ducts.展开更多

Her past medical history included hypertension and hyperlipidemia. A 6.9 cm infrarenal abdominal aortic aneurysm, with a left ectopic pelvic kidney and two aberrant renal arteries, one each from the left and right common iliac arteries was found on computed tomography. Because of the high risk of rupture, surgery was recommended and an endovascular aneurysm repair was performed. The antegrade flow of the aberrant renal artery from the left common iliac artery was preserved. The right aberrant renal artery was covered with stent graft. The patient’s serum creatinine level remained unchanged throughout the postoperative course, with an uneventful postoperative recovery.展开更多
