Abstract
Background. Urethral
stricture is one of the most common complications after urethroplasty.
And nowadays a growing number of congenital urethral diseases is
observed. It is obvious that there is a huge amount of urethroplasty
needed all over the world. Material and Methods. 15 patients with
urethral strictures were included in the conducted prospective research.
All patients underwent a complex urology investigation consisted of
uroflowmetry, urethrography and urethroscopy. Most of strictures were
located in penile urethra, their length varied from 1 to 5 mm. All
patients enrolled in the study had the only single stricture. After
investigation internal visual urethrotomy was performed with one-time
stenting using individual prepared titanium nickelide stent. Stent was
in urethra for 14-21 days. It had been evacuated from urethra and
uroflowmetry, urethrography and urethroscopy were performed. Results and
discussion. All patients have good result of uroflowmetry in the
postoperative period. The results of urethrography and urethroscopy have
also showed that there were no urethral strictures. The longest
follow-up has lasted for 3 years. The efficiency of treatment is 93 %.
The repeated procedure was required in one case. Any complications of
this way of urethral stricture’s treatment haven’t occurred. Nowadays
laser urethrotomy is known to have a success rate about 84 %, but
follow-up period is still rather short. And also it is estimated that 65
% of all children with direct vision urethrotomy had a recurrence of
the stricture in 5 years. It is hoped that the announced way of
treatment of urethral stricture will be very perspective and will help
to solve such significant problem in pediatric urology as urethral
stricture. Conclusions. Stenting of urethra after internal visual
urethrotomy has good outcomes, and seems to be a very perspective
minimally invasive way of treatment of urethral stricture.
