Erectile Dysfunction in Chronic Kidney Disease and Hemodialysis Patients: A State-of-the-Art Review

Erectile dysfunction (ED) is a prevalent condition that significantly impacts the quality of life and overall well-being of affected individuals. This state-of-the-art (SotA) review covers literature published between 2020 and 2024, focusing on adult patients with chronic kidney disease (CKD) at various stages, including those receiving hemodialysis and individuals who have undergone renal transplantation. The pathophysiology of ED in CKD patients is multifaceted, involving vascular, neurogenic, hormonal, and psychological components that are further exacerbated by the metabolic and hemodynamic alterations associated with kidney disease. The review provides a comprehensive analysis of current diagnostic approaches, including clinical assessment tools, laboratory evaluations, and imaging modalities that aid in identifying the underlying causes of ED in CKD patients. Pharmacological treatments, particularly phosphodiesterase type 5 (PDE5) inhibitors, remain the cornerstone of therapy; however, their efficacy and safety in patients with renal impairment require careful consideration. Non-pharmacological interventions, such as lifestyle modifications, exercise regimens, and psychological support, are explored as integral components of a holistic management approach. Additionally, advanced therapeutic options, including intracavernosal injections, vacuum erection devices, penile prostheses, and emerging therapies such as low-intensity shockwave therapy, stem cell treatment, and gene therapy, are critically reviewed in the context of CKD. This review also examines the bidirectional relationship between ED and comorbidities commonly associated with CKD, including cardiovascular disease, diabetes mellitus, and metabolic syndrome. Special emphasis is placed on the impact of dialysis modalities and renal transplantation on erectile function, highlighting the challenges in managing ED in these specific patient populations. Moreover, the psychological burden of ED, coupled with the stigma associated with CKD and sexual health, underscores the necessity of a multidisciplinary approach that integrates nephrologists, urologists, psychologists, and primary care providers. Despite advancements in treatment modalities, challenges such as limited patient adherence, stigma, and disparities in healthcare access persist. Addressing these issues requires targeted educational initiatives and policy changes to enhance patient awareness and access to comprehensive care.
