Background and Purpose: Foreign bodies in the bladder present a challenge to the urologist. Previously, endoscopic extraction, with or without perineal urethrotomy, or open cystotomy were the only treatment choices. We describe a novel use of the Ho:YAG laser for the removal of intravesical foreign bodies. We further tested the laser on objects that have been reported in the literature to necessitate open cystotomy to determine their suitability for endoscopic removal.
Materials and Methods: The Ho:YAG laser is introduced through the cystoscope and used to cut large foreign bodies into a size that can be extracted through the urethra. We tested the Ho:YAG laser ex vivo on other objects that have been reported as intravesical foreign bodies. Results: We removed a large complex foreign body with the laser that would otherwise have necessitated open cystotomy. No injury or sequela was observed. Many commonly reported intravesical foreign objects seem amenable to similar treatment.
Conclusion: The Ho:YAG laser should be considered for use to facilitate removal of foreign bodies from the bladder.
