Abstract
Background: Urethral stricture is a disabling condition that remains prevalent due to the upsurge of sexually transmitted infections and traumatic lesions of the urethra during trauma of the pelvis in humans. Objective: Describe the epidemiological, clinical and radiological presentations of male urethral strictures. Method: It was a cross-sectional and descriptive study during a one-year period from January to December 2017 including all male patients presenting for a urethrocystography examination, at the Ngaoundere Radiology and Medical Imaging Center who agreed to participate. The urethrocystography technique depended on patient’s condition and was either retrograde, anterograde, or following intravenous urography. The examinations were performed with GE X-ray equipment using Kodak Dry View CRs. The interpretation was performed by a radiologist with at least five years of experience. The variables studied were age, clinic, history, uretrocystography technique and results. The data were collected using a previously established data sheet and processed with Sphinx Plus2 V5 and Microsoft Excel 2010 software. Results: 39 patients were enrolled in this study; the average age of our patients was 43.8 years with extremes of 4 and 76 years. The 50 - 60 age group (30.7%) was the most affected. Infection (53.9%) and trauma (23.1%) were the most common etiologies; dysuria (38.5%) and diminution of urinary flow (30.8%) were the most patient’s complaint. Retrograde urethrocystography (66.7%) was the most performed technic. Minimal bleeding in 46.2% of patients was the most common incident during urethrocystography; 76.9% of patients had a difficult urination and 7.7% an impassable urethral meatus. After interpretation, 84.6% of patients had urethral stenosis, which was associated with bladder diverticula (23%) and fistulas (15.3%). The stenosis was seated on membranous urethra (81.8%), tight type (45.4%), short (66.7%) and single (81.8%). The post-void residue was significant in 84.6% of cases and not significant in 15.4% of cases. 15.3% of the urethrocystographies were normal. Conclusion: Urethral stenosis in Ngaoundere mainly affects young adult; the main etiology is infectious, very often unique, short, and tight and the membranous urethra is the seat of predilection. Hence, to reduce the extent of pathology with its functional consequences and its impact on the socio-professional life in our context, the focus should be on sexually transmitted infectious.
Highlights
Stenosis of the urethra can be defined as a reduction in the size, more or less extended, of the urethral canal
Radiology is the basis for the diagnosis of urethral strictures; conventional imaging of the urethra with urethrocystography is easy to perform, available, reproducible and economical examination that can detect clinically relevant narrowing involving the urethra [3], making it the first choice imaging for suspicion of stenosis in developing countries
Understanding the epidemiology, clinical and radiological pattern of urethral strictures can identify risk factors for the onset or progression of the disease, which can be the subject of preventive measures to reduce the severity of the disease and health expenses, so the purpose of this work was to identify the etiological, sociodemographic, clinical and radiological features of urethral stenosis in the Ngaoundere Regional Hospital
Summary
Stenosis of the urethra can be defined as a reduction in the size, more or less extended, of the urethral canal It is a relatively common condition among men with a prevalence of 229 - 627 per 100,000 inhabitants or 0.6% of the population at risk; it affects men of all ages with a peak prevalence between 40 and 45 years and is very rare under 9 years [1] [2] [3]. Radiographic patterns of strictures, which included the number, site, types, length and associated radiographic findings as well as complications, were obtained from the contrast urethrograms It is a pathology of the adult in professional activity, provider of psychological disorders and disabling, which can generate significant medical, socio-economic costs and a negative impact on the quality of life of patients. 84.6% of patients had urethral stenosis, which
