perineal urethrostomy

Full Definition

Perineal urethrostomy involves creating a permanent or temporary urethral opening in the perineum, usually performed for severe proximal hypospadias where primary reconstruction is not feasible. This procedure may be used as a staged approach, allowing urethral tissue to mature before definitive reconstruction, or rarely as a permanent solution. The technique requires careful positioning to avoid sitting difficulties and social concerns while maintaining adequate urinary drainage.

Usage

Usage note: Specify whether temporary or permanent; typically temporary in modern pediatric practice.
