Priapism: etiology and management.

Priapism is a urologic emergency. All patients should receive prompt urologic consultation. Management is based on prompt recognition, differentiation between low- and high-flow priapism, reversal of any potential precipitating factors, and the use of corporal aspiration/irrigation combined with intracavernosal alpha-agonist injection therapy. It cannot be over-emphasized that severely prolonged erections are associated with the development of irreversible problems with erectile function and, therefore, immediate and aggressive management is mandatory.

Management of sickle cell priapism with etilefrine.

Intracavernous injections of etilefrine were effective in seven children with acute sickle cell priapism, and stuttering priapism resolved in five children after one to seven months of oral etilefrine. Compared with our previous reports in adults, etilefrine appears to be more effective in childhood.

Heparin-associated priapism.

A patient who developed priapism 7 hr after stopping an intravenous heparin infusion is described. Abnormal spontaneous platelet aggregation was demonstrated whilst on heparin treatment and is thought to play a role in the aetiology of heparin induced priapism.

"High-flow" priapism: treatment with superselective transcatheter embolization.

Hemodynamically, most cases of priapism occur as a result of venous outflow obstruction producing engorgement of the corpora cavernosa. In a small number of patients, however, the cause is uncontrolled arterial inflow, often from direct arterial trauma. The authors report two cases of arterial or "high-flow" priapism that were successfully treated with selective transcatheter embolization with autologous clot.

Homozygous sickle cell disease and priapism in the eastern province of Saudi Arabia.

Two adult sickle cell homozygotes from the eastern oases of the Kingdom of Saudi Arabia presented with severe persistent priapism. Each patient had a high Hb F of 24%, and their red cells were neither hypochromic nor microcytic. Priapism probably occurs more frequently in homozygous sickle cell disease than reported previously from this region. It would appear that a high fetal haemoglobin alone without hypochromia and microcytosis--features suggestive of co-existing alpha-thalassaemia--does not protect against this agonizing vaso-occlusive event.

Erection and priapism: a new physiopathological concept.

For normal erection two mechanisms are essential: the first provides increased arterial inflow, most probably this is obtained due to the activity of the intimal cushions within the arteriae helicinae and within the shunt vessels. The second mechanism uses increased arterial blood flow; this could be obtained due to the activity of the trabecular muscle fibers of the corpora cavernosa. In consequence, we would deal with two different types of priapism: one type--high-flow priapism--occurs at the level of the arteriae helicinae and the intimal cushions and provokes a high-flow situation, and the second type, with blood stasis in the corpora cavernosa, occurs at the level of the trabeculae due to persistent contraction of the smooth muscle fibers. The prognosis of the second type is much less favorable and should be cured by surgery within the first 48 h.

High-flow priapism and glans hypervascularization following deep dorsal vein arterialization for vasculogenic impotence.

Microsurgical penile revascularization is becoming an increasingly applied technique in patients with arteriogenic or mixed arteriogenic and venogenic impotence. Deep dorsal vein arterialization has been used successfully in selected patients. Aside from failure of the procedure and the occasional problems associated with vascular surgery, priapism and glans hypervascularization are specific complications of deep dorsal vein arterialization. Priapism in these cases is 'high-flow'; the functional arterial-cavernous fistula can overcome the maintenance of the flaccid state and cause persistent erection. Glans hypervascularization, a syndrome of glans enlargement, skin changes and pain secondary to excessive retrograde filling of the glans penis and corpus spongiosum, can result in urethral compression and glans ulceration. Along with the presentation of the case of a man who suffered both complications, we discuss their pathophysiology, prevention, and treatment.

Angiographic treatment of high-flow priapism.

Priapism can be successfully treated by unilateral or bilateral percutaneous transcatheter occlusion of the internal pudendal arteries. Occlusion should be reversible in order to avoid impotence. Embolization with an autologous clot satisfies this requirement because of clot lysis and consequent vessel recanalization. This treatment is the most specific therapy in 'high-flow' priapism. The authors describe extensively 5 cases which demonstrate the feasibility of the method by which sexual potency is preserved.

Creation of caverno-glandular shunt for treatment of priapism.

Caverno-glandular shunt was performed in 8 patients with priapism during the past 3 years. Complete and sustained detumescence was achieved immediately in all patients. Only one case developed a complication, viz. cavernositis which responded to antibiotic administration systemically as well as locally. This procedure was performed under local anaesthesia in 5 patients. The technical details and advantages of this procedure over conventional operations for priapism are discussed.

Malignant priapism due to a huge renal carcinoma.

Metastases to the penis from renal cell carcinoma producing priapism are very rare, as only 18 cases have been described since 1964. We present an additional case of priapism due to massive metastatic involvement of the corpora cavernosa in a patient with huge renal cell carcinoma, 28 cm in diameter, discussing the possible pathogenetic mechanism of such a rare condition.

Cold saline enema in priapism--a useful tool for underprivileged.

Priapism, prolonged painful erection of the penis, is a urological emergency. Untreated, the patient can end up with impotence. Various methods have been described for its treatment but the initial management remains conservative. This study presents our experience with the use of sedation followed by an ice-cold saline enema in the management of priapism.

A clinical case report of priapism treated with external RT.

The aim of this short communication is to present an extremely uncommon case of penile metastases from rectal adenocarcinoma treated with an external beam radiotherapy technique. A 76-year-old man affected by very painful priapism from penile metastases was treated with radiotherapy (30 Gy) for symptom relief. In the course of the radiotherapy treatment the patient reported gradual and continuous pain reduction. One month after the end of radiotherapy both the priapism and the pain had disappeared. Although the long-term prognosis remains poor, good quality of life was achieved in this patient.

Priapism associated with two atypical antipsychotic agents.

Priapism has been associated with many antipsychotic agents, including clozapine, risperidone, and olanzapine. This prolonged, usually painful, penile erection rarely results from the alpha-adrenergic blocking action of antipsychotics. A 22-year-old African-American man developed priapism during treatment with risperidone and, on a later occasion, during treatment with ziprasidone. The problem resolved only with substitution of other drugs for these antipsychotics. Certain patients may be more vulnerable than others to this adverse effect. Clinicians must be aware of such complications and use caution when prescribing these drugs.

Priapism: surgical or medical treatment?

Two cases of priapism treated with fibrinolysin (streptokinase) are presented. Comparisons are made between medical and surgical treatment in the literature. It is concluded that fibrinolysin may be useful in some cases of early priapism, but should be chosen only after serious consideration of the circumstance that its use precludes early surgery.
