Owing to the limited donor pool at transplant centers, grafts may be taken from marginal donors with congenital abnormalities, one of the most common of which is a fusion abnormality. Horseshoe kidneys may be transplanted to a single recipient en bloc or to 2 recipients after division. In our clinic, 3 grafts (1 obtained from a living donor and 2 from a deceased donor) were successfully transpl...

Primary carcinoid tumor of the kidney is a very rare entity (< 1%). About 90 cases have been reported in the literature. Carcinoid tumors appear over-represented in horseshoe kidneys compared with normal renal anatomy. Herein, we reported a 33-year-old male with primary renal carcinoid tumor arising from a horseshoe kidney. The tumor showed nests and trabeculea of uniformly polygonal cells sepa...

A preliminary report in 1965 described a conservative surgical procedure for the management of acute and chronic horseshoe anal fistulas. The operation has been used exclusively at the Ochsner Clinic for this problem since 1963. Forty-one patients were treated from 1963 to 1973. The paper reviews the pathology of acute and chronic horseshoe anal fistulas and describes the surgical procedure for...

We compute families of symmetric periodic horseshoe orbits in the restricted three-body problem. Both the planar and three-dimensional cases are considered and several families are found. We describe how these families are organized as well as the behavior along and among the families of parameters such as the Jacobi constant or the eccentricity. We also determine the stability properties of in...

Biological membranes create compartments, and are usually formed by lipid bilayers. However, in hyperthermophilic archaea that live optimally at temperatures above 80°C the membranes are monolayers which resemble fused bilayers. Many double-stranded DNA viruses which parasitize such hosts, including the filamentous virus AFV1 of Acidianus hospitalis, are enveloped with a lipid-containing membra...

INTRODUCTION Horseshoe kidney is the most common fusion abnormality in the kidney and occurs in 1 per 400 people with the male female ratio of 2:1.(1) Duplication of renal collecting system is the most common upper tract anomaly with an incidence of 0.5-0.8%.(2) Unilateral duplication is six times more frequent than bilateral duplication, with equal incidence on right and left sides.(3) However...

We herein report a case of 20-year-old man who underwent a contrast-enhanced computerized tomography of the pelvis for a workup of complicated urinary tract infection, which showed presence of classical horseshoe kidney and incidental left-sided infrarenal inferior vena cava (IVC). The left IVC joined the left renal vein and crossed anterior to the aorta, uniting with the right renal vein to fo...
