Treatment of malignant bladder tumors by iridium-192 wiring.
Small tumors of the mobile portion of the bladder may be treated by means of interstitial irradiation by iridium-192 wiring. Twenty-six tumors (mostly T1, but also T2 and T3) were treated by this procedure. Good results are attained in 89 per cent of 19 cases followed over three years. This method has the benefit of avoiding irradiation to the surgeon's hands, and of delivering to a specific site a dose of 6,000 rads. No bladder contraction was observed.
