Expected toxicity

• Urinary symptoms peaking at 2-3 weeks but persisting for 2-3 months

• 10-15 % risk of temporary catheterisation. Risk of permanent incontinence < 1%

• Impotence in 33% (if no hormones) with response to medication in 85%

• Side effects relate to T 1/2

of isotope (I 125

=60 days,

Pd 103

=17 days), so settle earlier with shorter T 1/2
