A method of providing medical treatment of the prostate area. A urethrally inserted apparatus having an outer sheath, and a removable obturator located within the sheath during insertion of the sheath into the urinary tract by way of the externally urethra orifice in the penis is disclosed. Once the sheath is inserted, the obturator portion is removed and a medication depositing structure is inserted into the sheath. The depositing structure carries selected medication, as for example, radioactive iodine seeds. The obturator may be provided with means for inserting a viewing lens element to assure that the appropriate location adjacent to the prostate is obtained. Once the medication depositing structure is adjacent a selected area in the prostate, the prostate is pierced by the depositing structure so as to position the medication within the selected area. The medication is released and the deposition structure is withdrawn from the sheath. Thereafter, the sheath is withdrawn from the urethra.
