Tubularized incised plate urethroplasty with or without dilatation in hypospadias repair: a comparative study

Abstract

Background. After tubularized incised plate (TIP) urethroplasty meatal and urethral dilatation is a common practice. There are some complication of uretheral dilatation like urethral bleeding,urethral perforation and creating a false passage. Moreover dilating the urethra regularly is physically or psychologically painful both for the child and the parents. The aim of this study was to justify the necessity of uretheral dilatation after TIP urethroplasty.Material and Methods. This study was a prospective, comparative study performed in Dhaka Shishu (Children) Hospital from July 2017 to June 2020. Total 60 respondents were participated in this study with maintain inclusion criteria. Respondents with primary distal and mid-shaft hypospadias where TIP urethroplasty was indicated, admitted in Dhaka Shishu Hospital during study period were included. Group 1 was assigned non dilatation group and Group 2 was assigned to regular urethral ditatation group after TIP urethro- plasty. Fistula formation, meatal stenosis and neourethral stricture were compaired between two groups. Informed written consents were taken from legal guardians. Data ware analyzed by SPSS Program.Results. In this study there was no significant difference of ages between two groups. In Group 2 10 %( 3)respondents developed urethrocutaneous fistula, 10% (3) respondents developed meatal stenosis and 3.33% (1)respondents developed neourethral stricture. On the other hand. In Group 1 10% (3) respondents developed urethrocutaneous fistula, 6.66% (2) respondents developed meatal stenosis. None of patient in Group 1 developed neourethral stricture.Conclusion. There was no significant difference in fistula formation, meatal stenosis and neourethral stricture in between regular urethral dilatation group and non-dilatation group after TIP urethroplasty.
