Evaluation of Factors Affecting Surgical Success in Megameatus Intact Prepuce Cases

Aim: Megameatus intact prepuce (MIP) is a rare form of hypospadias. Different meatal/urethral advancement and urethroplasty techniques are used in the treatment of MIP. This study aimed to evaluate the success of various surgical methods for the treatment of MIP. Materials and Methods: Patients who underwent circumcision, meatoplasty, and urethroplasty techniques due to MIP between 2011 and 2022 were included in this study. Surgical success was accepted as the absence of complications and/or the need for additional treatment. The statistical significance level was accepted as 0.05. Results: This study included 100 patients with a median age of 33 months. Of these, 94 patients were admitted to our center with untreated MIP, 5 presented after circumcision and 1 after MIP repair in another center. The urethral stent placement rate was significantly lower in those patients with a glanular meatus location as in patients who underwent the meatoplasty technique (p<0.001). The complication rate was significantly higher in the Duplay with Posterior Meatal Incision (DPMI) technique when compared to the other techniques (p=0.033). There were no significant differences between the meatoplasty, Duplay urethroplasty, Pyramid urethroplasty, and DPMI techniques in terms of the need for additional surgical intervention (p=0.102). None of the five previously circumcised patients who underwent Duplay urethroplasty experienced any complications. When the complication rates were compared between the patient group presenting with untreated MIP and those who underwent Duplay urethroplasty, no statistically significant difference was detected (p=0.534). Conclusion: According to the conclusions of this MIP series, prior circumcision or the preference for any specific surgical technique that preserves the urethral plate did not affect the success of MIP treatment.
