BACKGROUND: Megameatus intact prepuce (MIP) is a unique variant of hypospadias and is a clinically rare condition. Due to the anatomical characteristics of the MIP hypospadias variant presenting a unique challenge to surgeons, no single urethroplasty method provides a universal solution for all patients. The purpose of this study was to evaluate the outcomes of hypospadias after MIP repair by urethral plate-preserving urethroplasty.
METHODS: A retrospective study was performed on 25 coronal or distal MIP patients, with a median age of 8, with most deficiencies being discovered during their first hospital visit for phimosis. Correction with urethroplasty was performed for all patients; 5 underwent the Mathieu procedure, 13 underwent the tubularized incised plate (TIP) procedure, and 7 underwent the Duplay procedure. The 25 patients were followed up for 6 to 36 months to evaluate the surgical outcomes.
RESULTS: There were no significant differences in intraoperative bleeding, hospital stays, postoperative analgesia rate, and cure rate among the three surgical procedures. The operative time for the Mathieu procedure was longer than that for the TIP and Duplay procedures, which did not differ. Complications occurred in 4 of the 25 patients (16.0%), and the overall complication-free survival rate at 1 year after surgery was 80.5%. The age at the time of surgery, urethral plate width, urethroplasty length, surgical procedures, or meatal location (coronal or distal penis) were not independently predictive of complications.
CONCLUSIONS: The clinical manifestations of MIP are often concealed and then accidentally discovered during hospital visits for phimosis; thus, the actual incidence of MIP might be higher. The urethral plate should be preserved during MIP-correcting treatment, especially for coronal or distal MIP. The same satisfactory outcomes can be obtained with Mathieu, TIP, or Duplay urethroplasty.
