Renal vein thrombosis in early infancy is a complication of dehydration and prolonged hypotension. The onset is usually acute and the most common clinical signs are uni- or bilateral frank masses, hematuria, proteinuria and thrombocytopenia. In most cases, with conservative management, the late outcome is favorable. In the adult, renal vein thrombosis is often a silent complication of the nephrotic syndrome, the hypercoagulability of which may be an important factor in the pathogenesis of the thrombosis. Clinically, the presentation of a sudden complete occlusion is that of severe abdominal and lumbar pain with hematuria and loss of function of the kidney that suffers hemorrhagic infarction. Physical examination often reveals an enlarged kidney. With gradual occlusion, renal function is preserved. The initial diagnostic approach is with ultrasound studies and computed tomography; definitive diagnosis is established by renal venography or by selective renal arteriography. In general, a conservative approach including the use of anticoagulant treatment is preferred to surgical intervention. Priapism is a persistent painful penile erection due to ischemic or non-ischemic causes; therapeutic intracavernosal injection of papaverine is becoming the most common cause. In early and mild stages, aspiration of blood from the corpora cavernosa supplemented with intracavernosal irrigation with alpha-stimulating agents is the procedure of first choice; in late and severe ischemia, a shunt procedure may become necessary. Hepatic vein thrombosis occurs in association with a number of conditions considered predisposing factors including the use of oral contraceptives. The clinical picture may be that of an acute illness with abdominal pain, hepatomegaly, ascites and hepatic failure as well as early death. More often, the onset is insidious with slowly developing ascites and wasting. For the diagnosis, hepatic scintigraphy may be helpful but, at present, ultrasonography, computed tomography and magnetic resonance scanning are procedures of choice. There is, as yet, no adequate treatment. A fatal outcome may be prevented by surgical decompression of the congested liver and, in recent years, liver transplantation has been employed. Portal vein thrombosis, in children, is usually considered a complication of umbilical sepsis or a result of a congenital abnormality of the portal vein. In adults, the most frequent causes are hepatic cirrhosis and neoplasia. Clinically, there may be a sudden appearance of ascites with resolution in a symptom-free interval until the onset of other features of portal hypertension occur. Currently, ultrasound real-time imaging supplemented with Doppler capability, computed tomography and magnetic resonance scanning provide the necessary diagnostic information. Variceal hemorrhage is often the first major complication requiring treatment.(ABSTRACT TRUNCATED AT 400 WORDS)

Fourteen patients with various genitourinary disorders underwent arterial embolization. The procedure was useful in facilitating surgical removal of hypernephromas, in decreasing tumor-induced hypercalcemia, and in diminishing proteinuria secondary to renal failure. Patients with priapism due to excessive arterial inflow responded well. Results of embolization performed because of bleeding varied. When bleeding was localized to a single vessel or to an area supplied by such a vessel, embolization was successful. However, when hemorrhage was diffuse or due to multiple vessel inflow, arterial embolization was not entirely effective.

The application of evidence-based medicine to the management of adults with sickle cell disease (SCD) is currently primarily driven by clinical expertise and patient preference, as there is a paucity of randomized controlled trial (RCT) data to guide decision-making. A summary of SCD management principles in the areas of health care maintenance, transfusion therapy, treatment and prevention of painful episodes, acute chest syndrome, stroke, renal disease, contraception and pregnancy, and priapism is predominantly based on the authors' interpretation of available observational studies as well as the opinions of experts in SCD. RCTs impacting current practices address use of hydroxyurea to prevent painful episodes and acute chest syndrome, intensity of pre-operative transfusion, transfusion during pregnancy, and angiotensin-converting enzyme inhibitor therapy for proteinuria, but most issues in adult SCD care have not been rigorously studied and management may not be appropriately extrapolated from pediatric data. While challenging clinical problems need to be addressed by RCTs, there is also the need for development of practice guidelines using formal methodological strategies. This brief review is not a substitute for the process but provides a literature-based approach to making treatment decisions when caring for adults with SCD.
