The incidence of horseshoe kidney is about 1 in 400 cases. The presence of Wilms' tumor with a horseshoe kidney is unusual, and the occurrence of Wilms' tumor in a horseshoe kidney is estimated at 0.4 to 0.9% of all Wilms' tumors. We report the case of a 5-year-old boy who presented with a stage IV Wilms' tumor in a horseshoe kidney. The patient was treated with preoperative chemotherapy follow...

Horseshoe crabs (Limulus polyphemus) are bled by biomedical companies for the extraction of Limulus Amoebocyte Lysate (LAL), a clotting agent used in the detection of endotoxins. In 1998, the Atlantic States Marine Fisheries Conunission mandated tliat all biomedical companies collecting horseshoe crabs for the production of LAL study tl1e horseshoe crab mortality rates resulting from the compan...

Introduction. Horseshoe kidney is a congenital anomaly that presents unique challenges for the transplant surgeon. The mere presence of horseshoe kidney should not preclude consideration for transplantation. Case Report. A 33-year-old women suffering from end-stage renal disease underwent deceased donor renal transplant with a divided horseshoe kidney. We present a postoperative complication an...

The horseshoe kidney is a congenital fusion anomaly where both kidneys are fused at the lower poles. We report a case of horseshoe kidney in a 70 year-old Thai cadaver. This horseshoe kidney was associated with malformations of renal hila, sinuses, calyces and supernumerary arterial supplies from the dorsal part of the kidney. To our knowledge, the arterial supply to the horseshoe kidney from t...

Horseshoe lung is a rare congenital pulmonary anomaly in which the caudal and basal segments of the left and right lungs are joined together behind the pericardium at the height of cardiac apex. Most patients with horseshoe lung have many other cardiovascular anomalies typical of the scimitar syndrome or the hypogenetic right lung syndrome. We report on a patient with horseshoe lung not associa...

Two patients with renal pelvic stone in a horseshoe kidney who underwent a percutaneous nephrolithotripsy (PNL) are presented. Case 1 was a 36-year-old man with a 20 x 12 mm right renal pelvic stone in a horseshoe kidney. Case 2 was a 47-year-old man who had been followed up at our clinic for a horseshoe kidney and was found to have a 15 x 10 mm left renal pelvic stone. We found that percutaneo...

Discussion Horseshoe kidney was first recognised during a necropsy by DeCarpi in 1521, but Botallo in 1564 provided the first description and illustration of a horseshoe kidney. Horseshoe kidneys are believed to result from the median fusion of metanephric tissue due to mechanical forces. However studies have suggested that abnormal fusion of tissue associated with the parenchymatous isthmus of...

In this paper, we consider horseshoe motion in the planar restricted three-body problem. On one hand, we deal with the families of horseshoe periodic orbits (which surround three equilibrium points called L3, L4 and L5), when the mass parameter μ is positive and small; we describe the structure of such families from the two-body problem (μ = 0). On the other hand, the region of existence of hor...

We report a case of supernumerary kidney consisting of 4 renal moieties and including a horseshoe kidney. A 40-year-old woman presented complaining of intermittent vague abdominal pain and heaviness for a few years. Ultrasonography of the urinary tract revealed 2 kidneys on the left side and horseshoe kidneys located distal to them. The right horseshoe kidney was of small size. Further imaging ...
