[Clinicopathologic analysis of 5 cases of urachal adenocarcinoma.].

Objectives: To summarize the long-term results of patients with urachal carcinoma treated in our center.

Clinical Cases: The mean age at diagnosis was 48 years. The tumor stage according to Sheldon´s staging was IIB in two, IVA in one and IVB in two cases.

[Orthotopic kidney transplant (OKT): An alternative when heterotopic transplant is not feasible.].

Kidney transplant is the treatmentof election of end-stage chronic renal disease, usually being heterotopic extraperitoneal in the iliac fossae, with successful results. This technique can be challenging or even not feasible, usually in cases of severe vasculopathy or previous grafts, so urologists should consider alternatives such as orthotopic transplant. MATERIAL AND METHODS: We present three cases oforthotopic kidney transplant (OKT) made in Cruces University Hospital from 2001 to 2019, out of 2580 cases.

[Pancreatic metastasis of primary kidney cancer: A presentation of a serie of clinical cases and revision of the literature.].

Objective: Kidney cancer is around 2-3% of malignant tumours in adults. It has an important tendency to metastasize, being the most affected organs lungs, liver,brain, bone and adrenal glands. The pancreas is a rare site of kidney metastasis, with an incidence of 1-2.

[Renal cell carcinoma in von Hippel-Lindau disease. Nephron sparing surgery.].

Objectives: We reviewed the feasibility and safety of nephron sparing surgery for renal cell carcinoma in patients with von Hippel Lindau (VHL) disease.

Methods: We selected 22 patients with (VHL) disease with a mean age of 43 (range 30-56), from whom 16 underwent radical nephrectomy or nephron sparing surgery at our department between 2000 and 2015.

Results: A total of 33 tumors were treated, by either tumorectomy (n=20), partial nephrectomy (n=5), percutaneous renal radiofrequency ablation (n=3) edaor radical nephrectomy (n=5).
