Low-molecular-weight heparin (LMWH) therapy has recently been proposed as a cause of ischemic priapism. The evidence, however, remains scarce, as there are very few published cases of LMWH-induced priapism to date. The implications of such events are significant as ischemic priapism is a medical emergency. In current clinical practice we are seeing a trend towards LMWH therapies replacing unfractionated heparin (UFH). As LMWH therapies continue to gain favor, we will potentially see more cases of LMWH-induced priapism...

BACKGROUND: Despite the fact that priming with sex steroids in prepubertal children before growth hormone (GH) provocative tests is recommended, there is an ongoing controversial discussion about the appropriate age of the children, the drug used for priming, the dose and the period between priming and the GH test. Interestingly, there is no discussion on the safety of this procedure. To date, only little data have been available on the possible side effects of priming with testosterone...

Sickle cell disease (SCD)-associated priapism is characterized by decreased nitric oxide (NO) signaling and downregulated phosphodiesterase (PDE)5 protein expression and activity in the penis. Priapism is also associated with testosterone deficiency, but molecular mechanisms underlying testosterone effects in the penis in SCD are not known. Given the critical role of androgens in erection physiology and NO synthase (NOS)/PDE5 expression, we hypothesized that testosterone replacement to eugonadal testosterone levels reduces priapism by reversing impaired endothelial (e)NOS activity and molecular abnormalities involving PDE5...

The article describes a case of successful managenent of arterial priapism in a patient with a stab wound in the perianal area. Timely performed angiography revealed a pathological connection between a. Uretralis sinistra and spongy body. Disruption of the abnormal shunt resulted in immediate relief of erection with further preservation of erectile function. At the 3 and 6 months follow-up visits there were no signs of cavernous fibrosis or erectile dysfunction. The authors analyze the entire sequence of events in the management of the case, identify shortcomings, determine their significance and consider their prevention...

Fabry disease is a glycosphingolipidosis caused by deficient activity of α-galactosidase A; it is one of a few diseases that are associated with priapism, an abnormal prolonged erection of the penis. The goal of this study was to investigate the pathogenesis of Fabry disease-associated priapism in a mouse model of the disease. We found that Fabry mice develop late-onset priapism. Neuronal nitric oxide synthase (nNOS), which was predominantly present as the 120-kDa N-terminus-truncated form, was significantly upregulated in the penis of 18-month-old Fabry mice compared to wild type controls (~fivefold)...

PURPOSE: Lumbar spinal stenosis is characterized by the narrowing of the spinal canal, which subsequently induces impingement of neural elements in the lumbar spine. Thus, symptoms of lumbar spinal stenosis are typically associated with damage to those neural elements. Herewith, we target the genitourinary symptoms of lumbar spinal stenosis and the importance of differentiating these symptoms from other genitourinary pathologies, namely benign prostatic hyperplasia. MATERIALS AND METHODS: MeSH and keywords relevant to lumbar spinal stenosis and the organs of the urinary tract were used to a guide a literature search on MEDLINE...

The treatment of recurring low-flow priapism with the usual medications is still unsatisfactory. The case of an otherwise healthy young man experiencing low-flow priapism at the age of 31 is presented. A reason for his condition could not be identified. Over the course of several months, he required emergency urological treatment more than ten times. Treatment with cyproterone acetate (Androcur® 50 mg/day) stopped the spontaneous erections, but resulted in erectile impotence, reduced motivation, decreased interest in sex, weight gain of 10 kg, breast enlargement combined with touch sensitivity on both sides, and hair loss on both legs...

Low flow priapism is a urologic emergency because it leads to erectile dysfunction due to cavernosal fibrosis. Several treatments exist, including cavernosal aspiration, washing with or without alpha-mimetic agent or shunting surgery. In case of failure of these methods or prolonged priapism (superior to 36 hours), the option of early penile prostheses implantation should be discussed with a motivated patient in order to improve sexual satisfaction.

Since ancient times, the physicians of Antiquity noted the occurrence of priapism in some spinal cord injuries. Although priests saw it as a consequence of curses and witchcraft, after clinical observations of the Middle Ages and Renaissance, first medical hypotheses emerged in the 17(th)-19(th) centuries completed and argued by neuroscience and neurology developed in the European laboratories and hospitals. This study aims to present a short overview of the history of clinical observations of posttraumatic male priapism after spinal cord injuries since Antiquity until the beginning of the 20(th) century...

INTRODUCTION AND OBJECTIVES: Implantation of a penile prosthesis in a patient with significant corporal fibrosis can pose a significant challenge to the surgeon, necessitating the knowledge of specific techniques used to dilate and close aggressively scarred corpora. The objective of our instructional video is to discuss 2 techniques used to approach corporal fibrosis: proper and safe use of cavernotomes for dilation and use of narrower prostheses. METHODS: In this video, we present a 53-year-old man with a history of priapism 3 years ago that lasted 4 days in the setting of trazodone use...

OBJECTIVE: The pathogenesis of recurrent priapism is currently being investigated based on the regulation of the phosphodiesterase 5 (PDE5) enzyme. We explored the daily use of PDE5 inhibitors to treat and prevent priapism recurrences. METHOD: We administered PDE5 inhibitors using a long-term therapeutic regimen in seven men with recurrent priapism, with a mean age of 29.2 years (range 21 to 35 years). Six men (85.7%) had idiopathic priapism recurrences and one man (24...

REVIEW

Stuttering priapism is rare and under-investigated clinical entity. Although it shares similarities with ischaemic priapism, by definition, stuttering priapism has distinct characteristics that advocate for a different management in the clinical setting. Therefore, the management of stuttering priapism aims primarily to prevent recurrence rather than the resolution of spontaneous attacks. A multimodal approach and the individualization of each case are essential because of the diversity of the condition and the plethora of proposed therapeutic strategies...

The hyperhemolysis paradigm that describes overlapping "hyperhemolytic-endothelial dysfunction" and "high hemoglobin-hyperviscous" subphenotypes of sickle cell disease (SCD) patients is based on North American studies. We performed a transversal study nested in the CADRE cohort to analyze the association between steady-state hemolysis and vascular complications of SCD among sub-Saharan African patients. In Mali, Cameroon, and Ivory Coast, 2,407 SCD patients (1,751 SS-Sβ(0), 495 SC and 161 Sβ(+)), aged three years old and over, were included at steady-state...
