- True phimosis is the pathologic inability to retract the foreskin over the glans of the penis as a result of scarring.
- The inability to retract a normal, supple foreskin is not true phimosis.
- The foreskin is rarely retractable at birth due to normal adhesions between the glans and the inner prepuce.
- ∼90% are retractable by 3 yr of age, and 99% are retractable by 17 yr, as the epithelial cells that comprise smegma are shed.
- Parents should be instructed not to forcibly retract the foreskin.
EtiologyPossible causes of true phimosis include:
- Trauma from forcible retraction of the foreskin
- Repetitive bouts of diaper dermatitis
- Recurrent balanoposthitis
- Poor hygiene
- Poorly performed circumcision
