[Urethral stenosis in children. Apropos of 33 pediatric cases]
Insights
Endoscopic internal urethrotomy is highly effective for treating pediatric urethral stenosis, especially for recent and short strictures. Urethroplasty is less successful for complex or previously operated cases.
Area of Science:
- Pediatric Urology
- Surgical Innovation
- Medical Device Technology
Context:
- Urethral stenosis in children is a rare condition.
- Limited research exists, with only five retrospective studies published between 1961 and 1993.
- A significant number of cases involve iatrogenic causes or complications from hypospadias repair.
Purpose:
- To evaluate the efficacy of different treatment modalities for pediatric urethral stenosis.
- To compare the success rates of endoscopic internal urethrotomy and urethroplasty.
- To identify factors influencing treatment outcomes in pediatric urethral strictures.
Summary:
- Thirty-three children with urethral stenosis (ages 2.5 months to 17 years) were analyzed.
- First-line endoscopic internal urethrotomy achieved a 91% success rate, particularly for short, recent stenoses.
- Urethroplasty had a lower success rate (50%), often indicated for complex or multi-operated cases.
Impact:
- Endoscopic internal urethrotomy is a highly effective first-line treatment for pediatric urethral stenosis.
- The study highlights the importance of timely intervention and appropriate technique selection.
- Findings guide clinical decision-making for managing pediatric urethral strictures, improving patient outcomes.
Abstract:
Urethral stenosis in children is rare. Between 1961 and 1993, only five specific retrospective studies were published. Between January 1987 and December 1992, thirty-three children, i.e. thirty boys and three girls, were observed in our institution for urethral stenosis. Their ages ranged from two and half months to seventeen years. Etiology was congenital in six, traumatic in two, inflammatory in two and iatrogenic in thirteen patients. In additions, ten stenoses were consecutive with hypospadias repair. Seventeen patients underwent first-line endoscopic internal urethrotomy. Success rate was ninety-one percent. Two patients underwent a successful second similar procedure. Repeating this procedure more than twice and second-line urethrotomy doesn't improve success rate. It appeared that internal urethrotomy proved to be more effective in short and recent stenosis. Fourteen patients underwent urethroplasty by using various techniques, of whom only five first-line urethroplasty. Its indication in case of multioperated or complicated stenoses may explain the poor global success rate of about fifty percent.
