Abstract
It was a retrospective and descriptive study conducted in the urology division of Yalgado Ouedraogo University Teaching Hospital from October 2009 to September 2014. Sixty three (63) male patients with anterior urethral stricture disease were included. All the patients have their diagnosis confirmed by voiding retrograde cystourethrogram (VCUG) or during surgical intervention. Anterior urethral stricture constitutes 41.1% of all urethral stricture. Hospital prevalence was 4.2%. Patient average age was 50.5 years. Dysuria and urinary retention were the major complaints representing respectively 66.7% and 33.3%. The infectious cause of urethral stricture was 71.1% of cases, followed by iatrogenic and traumatic causes with respectively 17.4% and 11.1% of cases. Voiding retrograde urethrocystogram (VCUG) was the only diagnostic procedure. Single urethral stenosis of the anterior urethra was about 88.8% while multiple stenosis constituted about 11.2%. Bulbar urethral stricture was the major location for the stenosis. Urine analysis was performed on 82.5% patients and ruled out urinary infections in 69.2% of cases with identification and isolation of Escherichia Coli in 77.7%. Majority of patients (61.9%) had open surgery of which 39.7% had end to end resection and anastomosis. Dilatation constituted 33.3% of treatment of the stricture of the anterior urethra. No endoscopic treatment was registered. At the removal of the catheter, all were successful but with time, the success rate was 87% at 6 months, 89.7% at 12 months, 85.2% at 18 months 63.1% at 24 months.
Highlights
Urethral stricture is a permanent reduction of the lumen of urethra, or even the complete obliteration of its canal, which reduces the urinary flow from the bladder to the exterior whatever the level and the etiology of the stricture
The etiology of the anterior urethral stricture was infectious in 71.4% of cases, followed by iatrogenic and traumatic ones with respectively 17.5% and 11.1%
The voiding retrograde cystourethrogram (VCUG) allowed in all cases to locate the seat, the number of stenosis and to appreciate the length of the stenosis
Summary
Urethral stricture is a permanent reduction of the lumen of urethra, or even the complete obliteration of its canal, which reduces the urinary flow from the bladder to the exterior whatever the level and the etiology of the stricture. The anterior part of urethra goes from the end of the membranous portion to the urethral meatus. It can be subdivided into bulbar and penile urethra. The symptomatology of urethral stricture is univocal and represented by dysuria or urinary bladder retention. Infectious aetiologies are decreasing in developed countries compared to traumatic and iatrogenic aetiologies [1]. This does not seem to be the case in our context, despite the lack of epidemiological studies. We have conducted a retrospective study in order to highlight the management of the anterior urethra stricture at Ouagadougou university teaching hospital
