Basics
Description
- 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
Etiology
Possible causes of true phimosis include:- Trauma from forcible retraction of the foreskin
- Repetitive bouts of diaper dermatitis
- Recurrent balanoposthitis
- Poor hygiene
- Poorly performed circumcision
- Congenital anomalies
