Effect of early urethral dilatation in prevention of complications in hypospadias patients after urethroplasty

Introduction: Hypospadias is a common congenital malformation in boys. One of thecommon surgical techniques for correction of hypospadias is (Tubularized Incised Plateurethraplasty=TIP). Meatal stenosis and fistula formation are known post-operativecomplications. The purpose of our study was to evaluate the effect of early urethraldilatation in prevention of post operative complications. Methods: A randomized clinical trial including 60 patients with distal hypospadias whounderwent tabularized incised plate urethroplasty with or without dilatation was conductedin Bandar Abbas children hospital in 2011. Patients were divided in two groups. Thenumber of the patients and mean age were not different in two groups. Urethral dilatationwas started in first group at two weeks following surgery and continued for six months.The patients of second group were followed without urethral dilatation. All patients werefollowed for occurance of complications for one year. Chi-Square and t-test were used tocompare the groups. Results: In the first group the early fistula, late fistula, stenosis, hematoma, urinaryinfection, cutaneous necrosis, and wound dehiscence were developed in 16.7%, 6.7%,10%, 26.7%, 13.3%, 10%, and 20% of the patients, respectively. In the second groupthese complications were seen in 10%, 6.7%, 3.3%, 13.3%, 6.7%, 3.3%, and 6.7% ofthe patients, respectively. Statistical analysis of results showed no significant differencesbetween two groups in rate of complications.Conclusion: Early urethral dilatation after urethroplasty has no significant effect on postoperativecomplications.
