ABSTRACT
INTRODUCTION:
Urethral stricture disease is still a major problem in men. Many procedures are available for the treatment of urethral strictures; urethral dilatation is one of the oldest. The blind dilatation of urethral strictures may be a difficult and potentially dangerous procedure. The purpose of this study was to describe safe urethral dilatation using amplatz renal dilator and to report outcomes. MATERIALS ANDMETHODS:
From 2010 to 2014, a total of 26 men with primary urethral strictures were managed by urethral dilatation using amplatz renal dilators. The parameters analyzed included presentation of patients, retrograde urethrography (RGU) findings, pre-and postoperative maximum flow rate (Qmax) on uroflowmetry (UF) and post-void residual urine (PVR). Patients were followed-up at 1.6 and 12 months. The technique described in this paper enables such strictures to be safely dilated after endoscopic placement of a suitable guidewire and stylet over which amplatz renal dilators are introduced.RESULTS:
The mean age of the patients was 57.6 (35-72) years. The median stricture length was 0.82 (0.6-1.5)cm. Pre-operative uroflowmetry showed Qmax of 7.00 (4-12) mL/sec and ultrasonography showed PVR of 75.00 (45-195)mL. Postoperatively, Qmax improved to 18.00 (15-22)mL/sec (p<0.001) at 1 month, 17.00 (13-21)mL/sec (p<0.001) at 6 months and 15.00 (12-17)mL/sec (p<0.001) at 12 months. The post-operative PVR values were 22.50 (10-60)mL (p<0.001), 30.00 (10-70)mL (p<0.001) and 30.00 (10-70) mL (p<0.001) at 1.6 12 months, respectively. The median procedure time was 15.00 (12-22) minutes. None of the patients had a recurrence during a 12-month period of follow-up.CONCLUSION:
Urethral dilatation with amplatz renal dilators avoids the risks associated with blind dilatation techniques. This tecnique is a safe, easy, well-tolerated and cost-effective alternative for treatment of urethral strictures.
