Penoscrotal transposition: Long-term outcome in 29 patients

Area of Science:

• Pediatric Urology
• Genitourinary Surgery
• Congenital Anomalies

Background:

• Penoscrotal transposition (PST) is a rare congenital anomaly involving abnormal positioning of the penis and scrotum.
• PST can be associated with other genital anomalies such as hypospadias and chordee, complicating surgical management.
• Surgical repair aims to correct the anatomical malposition and restore normal function.

Purpose of the Study:

• To evaluate the efficacy and outcomes of a modified Glenn-Anderson technique for surgical repair of penoscrotal transposition in children.
• To assess the reliability and durability of this surgical approach in a pediatric cohort.

Main Methods:

• A retrospective review of 29 pediatric patients undergoing PST repair between 2004-2022.
• Patients were treated with a modified Glenn-Anderson technique, including scrotal flap utilization and testicular repositioning when indicated.
• Surgical repair was performed as part of one-stage genitoplasty, staged hypospadias repair, or as an isolated procedure.

Main Results:

• The modified Glenn-Anderson technique demonstrated successful outcomes in correcting penoscrotal transposition.
• Postoperative complications were observed in a minority of patients, with no complications reported in the group undergoing isolated PST repair.
• Various hypospadias repair techniques were utilized in conjunction with PST correction, with differing complication rates.

Conclusions:

• The modified Glenn-Anderson technique is a reliable and durable surgical option for penoscrotal transposition in the pediatric population.
• Careful long-term monitoring of these patients into adolescence is recommended to ensure sustained functional and cosmetic results and to identify any need for re-operation.
