The Urology Department is divided into three distinct sections: Functional and Reconstructive Urology, Kidney Transplantation, and the Functional Urological Oncology Unit. There are also two working groups in the areas of urolithiasis and andrology.
The Nephrology Department consists of three sections: Clinical Nephrology, which deals with acute and glomerular pathology, Dialysis, and Kidney Transplantation. In addition, there is a Vascular Access unit and a unit that leads home replacement therapies (home haemodialysis and peritoneal dialysis) and a therapeutic apheresis unit.
Structurally, the Institute has 55 hospital beds distributed across two general wards (nephrology and urology) and one intermediate care ward. It also has a day hospital that performs around 6,000 sessions per year, a urological diagnostics unit where both diagnostic and therapeutic tests are carried out, performing more than 8,000 and more than 11,000 procedures per year, a therapeutic apheresis unit that performs around 2,000 apheresis procedures per year, two haemodialysis units (one in the hospital at the Villarroel Site, which treats both chronic and acute patients, and an outpatient unit at the DIRAC centre, located on Carrer Manso, which treats around 80 chronic patients), the home therapy unit (peritoneal dialysis and home haemodialysis), which treats approximately 120 patients per year, and the clinical trials unit.
