Aspects épidémiologiques, cliniques et prise en charge de sténose urétrale chez l’adulte dans un Hôpital de District de Ngaoundéré, Cameroun

Abstract

Introduction: the aim was to determine the epidemiological, clinical aspects and the management of these patients in Ngaoundere Protestant Hospital (HPN). Methods: we conducted a retrospective review of complete medical records of patients hospitalized for urethral stenosis in the Department of Urology at the Protestant Hospital of Ngaoundéré over a one-year period (January 2013 to January 2014). Results: out of 69 registered medical records, a total of 57 patients files (all male) were identified for review. The average age was 52.6 (19-85 years). The most represented age group was 41-60 years. Urethral stenosis accounted for 0.6% of consultations, 11.36 % of surgical hospitalizations and 6.96% of surgical procedures. Dysuria (70, 17%) was the main reason for consultation. Etiologies included infections (52,63%), traumas (26.32%) and iatrogenic problems (21.05%). All patients underwent CBEU which allowed to isolate gonococci (14,03%) and Escherichia coli (21.05%), the remainder of the urine culture was sterile (64.91%). 28 patients (49.12%) underwent retrograde uretrocystography (RUC), of whom 26 with anterior stenosis (92,85%). Internal endoscopic urethrotomy (IEU) was the most common surgical procedure (58%). Stenosis mainly occurred at the level of the bulbar and peno-bulbar regions. The rate of healing was 87,73% vs 12.27% of recurrences. Conclusion: urethral stenosis is frequent in the Protestant Hospital of Ngaoundéré; patients requiring medical consultations are often in complex medical conditions. Internal endoscopic urethrotomy has shown plausible results.
