Guide wire-assisted urethral dilatation for urethral strictures in pediatric urology
1Urology Unit, Royal Children's Hospital, Parkville, Victoria, Australia.
Purpose:
The aim of this study was to report the results of 32 cases of dilatation of urethral stricture using a guide wire and sheath dilator technique supplemented by clean intermittent catheterization if further stabilization of the urethral stricture was felt warranted.
Methods:
The procedure involves insertion of a straight flexi-tip lubricated guide wire through the urethral stricture under cystoscopic guidance followed by insertion of a series of sheath dilators. Dilatation was followed by insertion of a Foley catheter, which was left in situ for 1 to 3 days. Patients underwent repeat cystoscopy to evaluate the urethra for recurrent stricture and those with a recalcitrant stricture were commenced on clean intermittent catheterization (CIC) to stabilize the narrowing.
Results:
Thirty-two patients were included. They have been followed up for up to 2(1/2) years after their last cystoscopy (mean, 16 months). Thirteen of 32 patients had more than 4 dilatations under anesthesia. Twelve patients had undergone CIC postoperatively. Complications included a urinary tract infection in 3 boys and bladder spasms in one. No false passage or sepsis occurred with this approach.
Conclusions:
Guide wire-assisted urethral dilatation helps avoid risks associated with blind dilatation techniques and appears to be a safe and simple alternative for management of urethral strictures in pediatric urology.
