[Chyluria of non-parasitic origin. Presentation of a case and review of the literature]. / Quiluria de origen no parasitario. Presentación de un caso y revisión de la literatura.

Chyluria is defined as the lymph reflux to the urinary collecting system through fistulous communications secondary to lymphatic stasis caused by obstruction of the lymphatic flow. Filariasis is the most frequent cause of chyluria, which is endemic in some areas, mainly in the Asian continent. In our environment chyluria is extremely rare, most cases being due to non-parasitical causes: tumours, abscesses, trauma, tuberculosis, congenital, etc. A patient case of chyluria in a 39 year-old male with background of chest trauma in which the source of chyluria was discovered to be an obstruction of the chest duct due to post-traumatic aneurysm of the aortic notch. The picture of chyluria ceased immediately after surgery, an aneurysmal resection with replacement with an aortic prosthesis. Considering the infrequency of chyluria in our environment, a literature review is made, explaining the most frequent etiological data, as well as accompanying clinical signs, diagnostic means and conservative and surgical procedures in the treatment of this process.

[Primary abscess of the psoas. Report of 3 cases and review of the literature]. / Abcesos primarios del psoas. Aportación de tres casos y revisión de la literatura.

Three cases of abscesses rated as primary of the psoas, after dismissing any likely cause that can be involved in the genesis of secondary abscesses of the psoas, are presented. A review of the literature is made, emphasizing the etiological change in the psoas' abscesses as well as the possible causes involved in the etiopathology of this picture which appears to be caused by distant dissemination from a septic nucleus. This theory is also supported by over 80% cases where Staphylococcus aureus is the causative organism. Reference is made to which clinical data is most relevant and to the value of the traditional diagnostic procedures: simplex x-ray, u.i.v., ultrasound techniques, radionuclides and CAT, the latter being the ideal diagnostic procedure in these processes. Finally, different therapy approaches are presented. Percutaneous draining (supported by ultrasound scanning and CAT) appears to have greater acceptance by most authors, relegating the surgical drainage for selected cases.
