sildenafil-citrate and Urinary-Bladder--Neurogenic

To perform a review and update of the antiphospholipid syndrome summarizing its urological presentations.. A complete bibliographic search was performed through PubMed MEDLINE and articles were reviewed with special attention to those bibliographic references about urological presentations. We document the unique and unpublished case of a patient with neurogenic bladder secondary to antiphospholipid syndrome.. The antiphospholipid syndrome is an acquired autoimmune systemic disease generating a permanent hypercoagulability status with recurrent multiorgan thrombotic events due to circulating antiphospholipid antibodies. It may be secondary to a heterogeneous group of diseases (mainly lupus) and drugs, or primary if it appears isolated without any demonstrable systemic disease or concomitant medication. It is mainly characterized by venous or arterial recurrent thrombosis, recurrent abortion, thrombocytopenia, and circulating antiphospholipid auto-antibodies. Treatment with anticoagulants and correction of the hypercoagulable status contributing factors, arterial or venous thrombosis, and vascular risk aim to avoid new thrombosis episodes. Genitourynary system may be affected in any of its parts, generally by arterial or venous thrombosis. Kidney is the most frequently affected organ, in addition to transplanted kidney grafts, adrenal glands, bladder and testicles. There is a relationship between antiphospholipid syndrome and infertility. For the first time, we describe bladder involvement presenting as hyperreflexic neurogenic bladder with detrusor-sphincter dyssynergia after spontaneous spinal cord thrombosis in an asymptomatic adolescent with primary antiphospholipid syndrome which was unknown before.

The incidence of DM is rapidly growing among Americans. DM will rival cancer and heart disease in terms of cost and suffering. The National Institute of Health is tripling the research dollars that are spent on diabetic-related research in an attempt to combat this disease. Urologists are on the front line in the diagnosis and treatment of the complications of DM. The complications of DM that we reviewed in this article, diabetic cystopathy and diabetic ED, can occur in the early stage of DM and often progress in a silent fashion. More awareness and interest are needed to improve our understanding of diabetic complications in urology. Exciting new approaches in the treatment of diabetic cystopathy and ED are being investigated.

Neurogenic bladder is a common complication of several central nervous system injuries. Statins and phosphodiesterase-5 (PDE-5) inhibitors are reportedly beneficial in neural injuries and urinary system dysfunction. The effect of simvastatin, sildenafil and tadalafil on several renal function indices of an animal model of neurogenic bladder was investigated.. Forty male rats were assessed in five equal groups. Dura mater and the cord were injured with an aneurysmal clamp at the level of T9-T10 in all rats except in sham group. The sham and control groups (treated by normal saline), simvastatin (4 mg/kg), sildenafil (5 mg/kg), and tadalafil (2 mg/kg) groups received treatment (i.p.) for seven consecutive days following injury. Renal system and motor functions were assessed at day 28 following injury. Data were analyzed by analysis of variance followed by the Student-Newman-Keuls post hoc test.. Simvastatin improved both the renal and the motor function compared with the control group. However, sildenafil and tadalafil could only improve the motor function but could not make any significant differences in renal indices in comparison with the control group.. Statins can effectively improve the motor and renal functions in a condition of renal dysfunction in a rat model of neurogenic bladder. PDE-5 inhibitors could help to improve motor function, but are not helpful in renal function, at least in short time.
