Management of lithiasis in pelvic kidney through laparoscopy-guided percutaneous transperitoneal nephrolithotripsy.

We report the case of a patient with pain and an abdominal palpable mass whose tests showed a left pelvic kidney with a 1.5-cm stone in the renal pelvis. We describe the successful management through videolaparoscopy-guided percutaneous transperitoneal nephrolithotripsy, stressing that this method is a therapeutic option in such cases.

Antibody-induced modulation of the leukocyte CD11b integrin prevents mild but not major renal ischaemic injury.

Background: CD11/CD18 beta(2) integrins are involved in leukocyte adhesion to the activated endothelium, and therefore represent a possible therapeutic target in the prevention of ischaemic acute renal failure (ARF).

Methods: To assess the effect of an anti-CD11b monoclonal antibody (mAb) in ischaemic ARF, uninephrectomized Fischer rats were subjected to 45 or 60 min of warm renal ischaemia, then received 1 mg of anti-CD11b mAb 5 min before reperfusion.

Results: After 45 min of ischaemia, renal function tests at 24 and 48 h were less altered in mAb-treated than in control rats, but after 60 min of ischaemia the same level of renal insufficiency was observed in the two groups.

In vivo effects of monoclonal antibodies against rat beta(2) integrins on kidney ischemia-reperfusion injury.

Background: Ischemia-reperfusion (IR) involves adhesion of leukocytes to the activated endothelium, leading to tissue damage. CD11/CD18 beta(2) integrins interact with their ligands on endothelial cells and may therefore represent a therapeutic target for the prevention of IR. We investigated the effects of three monoclonal antibodies (mAbs) that recognize epitopes of heavy or light chain of the beta(2) integrins on IR in kidneys.
