“…Segundo Chalhoub et al (2001a,b), ovinos da raça Ideal tem um CR de 13,7±3,67mm aos 29 dias de gestação e ovinos da raça Bergamácia apresentam um CR de 13,3±1,9 mm aos 27 dias de gestação. Consultando as tabelas de Evans & Sack (1973) e Noden & Lahunta (1990) para bovinos, observa-se que as informações nelas contidas também indicam a mesma fase gestacional. Adicionalmente, um CR de 12,3±1,3mm foi observado em bovinos entre os dias 25 e 30 de gestação por Assis Neto et al (2009).…”

Pesq. Vet. Bras. 31 (7) Mazama gouazoubira is a small-sized deer, which can be found in South America, from southern Uruguay to the north of Mato Grosso, Brazil. This study aimed to describe the fetal membranes and placenta of M. gouazoubira in the first third of pregnancy. Samples collected were macroscopically and microscopically analyzed. Uterus examination demonstrated univitelinic gestation with an embryo measuring a crown-rump length of 13mm. In the embryo analysis we could identify the pigmented eye, auricular hillocks, mesonephron and early metanephron, liver and its external prominence, stomach, thoracic members and buds of pelvic members. Placenta was oligocotyledonary and nine caruncles were found in the uterus. Gestational sac measured 15cm in length, and, as observed in the early gestation of domestic ruminants, cotyledons could not be identified macroscopically. A weak adhesion was found between caruncles and chorioallantoic membrane (cotyledons) forming the placentomes. The chorioallantoic membrane showed a well-vascularized allantoid composed by a thin layer of cells with stretched nucleus and cytoplasm. On the other side of the membrane, the chorion was composed by cubic cells with scant cytoplasm and large-rounded nuclei, features of trophoblast cells. Involving the embryo we identified a two-layered amniotic sac. Layers could be mechanically separated and had similar morphology, showing a non-vascularized squamous epithelium. There was no yolk sac in the gestational stage of this specimen. We concluded that the placenta of M. gouazoubira is an oligocotyledonary placenta, as observed in others cervids, and that the fetal membranes showed similarities with those from other domestic ruminants, including cytological characteristics. Further studies are required in order to determine the presence of the yolk sac and its regression time.INDEX TERMS: Yolk sac, chorioallantoic membrane, embryo, oligocotyledonary placenta, placentome.

“…Moinzadeh et al [15] performed LPN on 10 calves using the Helix Hydro-jet (Erbe Elektromedizia GmbH, Turbingen, Germany) at a pressure setting at 450 psi with BIClamp (Erbe Elektromedizia GmbH, Turbingen, Germany) and were able to perform on 18 of 20 kidneys without hilar control, with an operative time of 173 min and blood loss of 60 ml. Others have also used this technology in the porcine model with and without vascular control [16,17] with the use of metallic clips, or vascular clips and an endoscopic gastrointestinal stapler to secure the centrally located blood vessels and collecting system.…”

The techniques for management of small renal masses (SRMs) have evolved over the past several years. Radical nephrectomy can lead to an increased risk of chronic kidney disease, and the emphasis is now shifting to nephron-conserving techniques. Partial nephrectomy is now considered a standard of care for the management of SRMs, and laparoscopic techniques are becoming popular because they are minimally invasive. The kidneys are extremely vascular organs, and renal hemorrhage is a major cause of morbidity after laparoscopic partial nephrectomies. Control of bleeding and management of calyceal injuries can be difficult and make the procedure technically challenging. This review looks at the various modalities that are available to reduce bleeding and reviews some advances in the area of hemostatic maneuvers during laparoscopic partial nephrectomies.

“…Since then, waterjet cutting has become an established technique in different surgical fields [2]. The technique is used clinically for cutting soft tissues like liver tissue [3][4][5][6] and experimentally for dissecting spleen tissue [7,8], kidney tissue [9][10][11][12] and brain tissue [2,13,14]. Waterjets have also been investigated for cutting hard materials such as bone and bone cement [15][16][17][18].…”

Water Jet Assisted Laparoscopic Partial Nephrectomy Without Hilar Clamping in the Calf Model

Abstract: In this more stringent and robust survival calf model Hydro-jet assisted LPN can be performed without hilar vessel control, thus, completely avoiding warm ischemia. This approach has the potential to decrease the level of technical difficulty inherent in LPN.
