What type of administration is specifically used for cancer or incontinence treatment via the urethra?

The administration of treatment via the urethra is referred to as urethral administration. This method is specifically relevant for delivering medications directly to the bladder or urinary tract, often utilized in the treatment of conditions such as cancer or incontinence. By administering medications through the urethra, healthcare providers can target the affected area more directly, potentially improving the effectiveness of the treatment while minimizing systemic side effects.

Intravenous administration involves delivering substances directly into the bloodstream, typically used for rapid effects or for substances that would otherwise be poorly absorbed. Vaginal administration is used for medications intended to treat conditions specific to the vaginal area or for systemic absorption through the vaginal mucosa. Nasal administration allows medications to be absorbed through the nasal mucosa, typically used for local or systemic effects, but does not directly target the urinary system.

Thus, urethral administration stands out as the most appropriate choice for treating conditions like cancer or incontinence when targeting the urinary system.
