Erectile dysfunction pre and post kidney transplant recipients in Duhok city; cross sectional study

Introduction: Sexual dysfunction is a common problem in patients with chronic kidney disease. Disturbances in sexual function are noticed in early stages of chronic kidney diseases and deteriorate further as renal function declines. This is due to uremic effects, comorbid illness, anemia, hormonal disturbances, autonomic neuropathy, vascular diseases, hyperparathyroidism, hyperprolactinemia, side effects of medications, and psychosocial factors. Patients and method: This is a cross-sectional study which included 59 male patients who underwent renal transplantation for more than 6 months. The International Index of Erectile Function (IIEF-5) was adopted in our study to record the erectile function. Results: The mean age was 49.41 years, and the mean number of hemodialysis per month was 5.31. The cause of the chronic kidney disease was diabetes mellitus in 35.59%, glomerulonephritis in 20.34%, and hypertension in 16.95%, other causes were diagnosed in order of decreasing frequency. Most patients developed improvement in the erectile function after transplantation. There was significant correlation with 3 of the elements of the IIFE-5.i.e; penile hardness pre-penetration, Maintaining erection during intercourse, and Difficulty to maintain erection to complete the intercourse (p values 0.015, 0.011, and 0.023) respectively, and the overall improvement after transplantation which showed a p-value of less than 0.031, while there was no significant correlation with Confidence with erection and Satisfaction with intercourse before and after transplantation (p values 0.113 and 0.121) respectively. One of the patients (1.7%) developed severe dysfunction after that. Conclusion: ED is common sequel of chronic kidney disease. The etiology is multifactorial and may be worsen by advanced age, presence of diabetes mellitus and prolonged duration of hemodialysis. Renal transplantation has a positive impact on sexual function and lead to improvement of erectile dysfunction. Erectile dysfunction that persists after kidney transplantation is usually attributed to multiple preexisting comorbidities.
