An update on aspects and use of different experimental models applied in kidney transplant research is presented . This paper includes qualities, as long as similarities between most frequently used animal models and human clinical standards. Contributions of those models based on microsurgical or laparoscopic techniques are revised. The physiological consequences (hemodynamic, immunologic) of surgical technique (laparoscopy), applied in experimental models as long as non-heart beating organ donor models and organ preservation methods are also reviewed. Finally, an update of those models applied in research in prothocols of either immunosupression or xenotransplant is done.

Objective: [corrected] To indirectly address the adequacy of referrals from general practitioners (GP) to specialized care taking into account a previously agreed protocol on ten urological topics., Materials & Methods: The study analyzed all referrals to the Urology department originated in 10 primary care centres (135 GPs involved) throughout a 19-month period. Adequacy of 2841 referrals was checked. The urologist judged the referral as compliant (adequate) or not compliant (inadequate) with the terms of the protocol. Compliance per primary care centres was compared. Also referral adequacy corrected per centre and clinical topic was compared. The relationship between "absolute number of referrals" and "adequate referrals" was tested using a linear regression model., Results: 57.2% of the referrals were inadequate. Overall, no significant differences were detected between primary care centres. Nevertheless significant differences between centres were evident in terms of referrals due to renal colic and female urinary incontinence. 70% (94/135) of the GPs complied with the protocol in, at least, 50% of the cases. A strong association between "absolute number of referrals" and "adequate referrals" was evident (r2=0.86)., Conclusions: Overall compliance with the protocol was modest. While no significant differences between centres were detected in terms of adequacy of referrals certain conditions have to be locally revisited; most of the topics (particularly microhematuria) have to be revisited in every center.

Adrenal pseudocyst is the commonest type of benign lesions of adrenal gland althought is a very rare entity. Most of them are found as "incidentalomas" during imaging studies. A case of a patient with a left non-functioning and asymptomatic adrenal pseudocyst is reported. The diagnostic and therapeutic options are discussed and the literature is reviewed.

We report a case of renal artery stenosis after a living transplant kidney, treated successfully with percutaneous transluminal angioplasty (PTA) and vascular endoprosthesis. PTA is the initial treatment of choice for most patients with high grade transplant renal artery stenosis. Surgical revascularization is indicated if PTA cannot be done or is unsuccessful.
