[Modification of meatoglanuloplasty (MAGPI-Duckett) for treatment of balanic and coronal forms of hypospadia in children].
14 boys with balanic hypospadia (BH) and 23 boys with coronal hypospadia (CH) aged 9 months to 15 years were operated in 1997-2000. For 13 boys this operation was meatoglanuloplasty (MAGPI) by J. Duckett. Complications occurred in 4 boys: retraction (downwards) of the meatus (n = 2), urethral stenosis and urinary fistula (n = 2). 24 boys have undergone modified MAGPI operation. The modification consists in extended mobilization of the lateral parts of the head with longitudinal consecutive incisions along the head margin into the spongy bodies. The head is closed by suturing its mobilized margins with two rows of interrupted monofilamentous (PDS, prolene) sutures above the urethra. A variant of saving foreskin is possible when partial separation of the internal and external layers is made bilaterally with consecutive circular closure of the preputial sac. Phimosis is prevented by a relief longitudinal incision along the internal foreskin and transverse suturing. The patients were followed up for 2 months to 1.5 years. The original operation MAGPI provided good cosmetic and functional results in 9 boys(69.2%), satisfactory in 2 boys(15.4%), unsatisfactory also in 2 boys(15.4%). The modified MAGPI operation provided only good cosmetic and functional results. Thus, the proposed modification (MAGPI-Duckett) ensures a more reliable variant of meatoglanuloplasty in balanic and coronal hypospadia irrespective of the size and shape of the head, presence of the scaphoid fossa or meatostenosis. These additional procedures helped to reduce the number of postoperative complications and improved cosmetic and functional results.
