comparing mathieu and tubularized incised-plate urethroplasties forrepairing distal penile hypospadias: a single-center experience withlong-term outcome

Background: hypospadias is a congenital anomaly on the penis, in which the meatal orifice opens ventrally and proximal to thetip of the penis. in this regard, two common treatment methods are tubularized incised-plate urethroplasty (tip) and the mathieuincised-plate (mip) technique. the present study aimed to compare the early and long-term outcomes of tip and mipamongpatientswith distal penile hypospadias.objectives: the study was also to evaluate the postoperative functional outcome of hypospadias over a long-term follow-up.methods: fifty-nine patients were randomly selected and assigned to two groups (tip (n = 31) and mip (n = 28)). demographic information,preoperative findings, and postoperative complications were collected from the two groups. the hypospadias objectivescoring evaluation (hose) questionnaire and uroflowmetry were obtained to evaluate the long-term outcome of hypospadias repair.results: the success rates of the surgical tip and mip techniques were 71.0% and 82.1%, respectively. postoperative complications inthe tip group were three (9.7%) distal ucf and four (12.9%) meatal stenosis. in the mip group, two (7.1%) and three (10.7%) patientssuffered from distal ucf and meatal stenosis, respectively. moreover, 89.3% of the patients in the mip group and 80% of the patientsin the tip group had acceptable hose. regarding the uroflow rates in the mip group, 12% and 58% of the participants were below the5th percentile and above the 25th percentile, respectively. concerning the uroflow rates of tip, 32% of the patients were below the5th percentile, and 18% of the participants were above 25th percentile.conclusions: although there have been some reports on the superiority of tip, we found these two techniques at approximatelyequal levels with a slightly higher success rate for the mip regarding the early outcomes. with the exception of the long-term outcomesin cosmetic and functional evaluation, mip is superior to tip.
