To evaluate the factors affecting the results, as well as the success of two techniques, by retrospectively investigating cases of distal hypospadias in which the patients had undergone Mathieu urethroplasty or tubularized incised plate urethroplasty. We retrospectively evaluated 117 patients who underwent distal hypospadias repair. A percutaneous suprapubic catheter (Cistofix) and urethral split catheter were placed as a diversion in the 41 patients undergoing Mathieu urethroplasty. The Cistofix and urethral catheter were placed in 35 patients and a urethral catheter was placed in 41 of the patients who underwent tubularized incised plate urethroplasty. The success rates were compared according to the surgical technique, age, hypospadias status (primary or secondary), type of urinary diversion, and presence of chordee. No statistically significant difference in the success rate was found between the two techniques. Furthermore, the different types of diversion used in tubularized incised plate urethroplasty did not affect the success rate. When the success of primary hypospadias repair (n = 84) was compared with secondary hypospadias repair (n = 33), success in patients with secondary hypospadias was low. No difference was observed when operational success was compared in terms of patient age (older versus younger than 5 years of age) or the presence or absence of chordee. Our results have shown that tubularized incised plate urethroplasty should be preferred for distal hypospadias because of the better cosmetic results, invasive urinary diversions should be avoided, and the most importance should be given to the initial surgical intervention.
