Objective: To evaluate the management of erectile dysfunction (ED) in chronic kidney failure (CKF) patients in Congo. Patients and method: This was a cross-sectional study with prospective data collection over a period of 9 months, carried out in the nephrology departments of three hospitals in Congo. The IIEF-5 score was used to assess erectile function. We included all CRD patients with ED over 18 years of age. Results: The mean age of the patients was 54.4±(range: 20 years and 81 years). Cardiovascular risk factors were dominated by high blood pressure which accounted for 86 patients (91.5%). BMI was normal in 76 patients (80%). Grade 2 hypertension was noted in 47 patients (49.47%). Two patients (2%) did not have secondary sexual characteristics. The average duration of CKF was 3 years. The onset of ED was preceded by CKF in 92 cases (96.8%). The onset of ED was gradual in 72 cases (78.2%). The circumstance of the occurrence of ED was found in five cases (5.2%). Penile stiffness was low in 86 cases (90.5%). Sixty-four patients (67.4%) did not have a nocturnal erection. Other associated sexual disorders were decreased libido in 46 cases (48.4%), anorgasmia in 53 cases (55.8%) and premature ejaculation in 47 cases (49.47%). The mean IIEF 5 score was 11.38±4.44. Erectile dysfunction was severe in 43 cases (45.2%). Examination of the penis was normal in all cases. Erectile dysfunction was difficult to bear in 51 cases (53.7%). The testosterone level was between 5.5-32 nmol / L in 44 patients (68.8%). FSH and LH levels were increased in 60% of cases. The prolactin level between 1.8 -29.2 micrograms / l in 14 cases (70%). The medical treatment of erectile dysfunction concerned 36 patients (37.8%). Conclusion: ED has psychological consequences that accentuate the suffering of patients. Modification of these risk factors must be undertaken early. IPDE5 have improved the management of erectile dysfunction
