Objective: Penoscrotal transposition (PST) is a rare anomaly of the external genitalia characterized by malposition of the penis in relation to the scrotum. This transposition may be partial or complete and may be associated with hypospadias, chordee, and other anomalies. We have reviewed our experience with the surgical repair of PST utilizing a modified Glenn-Anderson technique. Materials and Methods: Twenty-nine patients with a median age of 5.6 years (8 months -15 years) underwent surgical repair of PST at our institution between 2004-2022. Of those, 20 (69%) had complete PST, while 9 (31%) had partial PST. All children were divided into three groups. In the first group of 8 (28%) children, repair of PST was an integral part of one-stage male genitoplasty; in the second group of 18 (62%) children, repair of PST was an isolated last stage of the staged hypospadias repair and the remaining 3 (10%) children underwent PST repair without the presence of hypospadias. All patients underwent modification of the Glenn-Anderson technique involving utilization of bilateral rotational advancement scrotal flap, complete de-tethering of the testis from the internal part of the scrotum when indicated, and relocation of the scrotal compartment in a normal dependent position. The follow-up ranged from 6 months to 18 years. Results: In the first group, five children (62%) underwent Onlay Prepucial Island Pedicle Flap (OIF) hypospadias repair, and three (38%) underwent Long Tubularized Incised Plate Repair (TIP). In the second group, 8 (44%) underwent OIF hypospadias repair, 2 (12%) had Long TIP repair, and the remaining 8 (44%) underwent staged hypospadias repair. Post-operative Clavien Dindo grade III presented among three patients in group I and only one patient in group II. In the third group, no postoperative complications were observed. Conclusion: Our data show that penoscrotal transposition correction utilizing the Glenn-Anderson technique is a reliable and durable surgery in the pediatric population. These children require careful monitoring till adolescence to ensure that no re-operation is needed.
