Dissolution of vesical calculi with Renacidin in a paraplegic man.

Vesical calculi are common in spinal cord injury patients. The majority are composed of magnesium ammonium phosphate, a compound readily soluble in the solvent Renacidin. We describe a paraplegic man with recurrent bladder stones in whom cystolitholopaxy was unsuccessful. His calculi were completely dissolved by continuous Renacidin bladder irrigation. We recommend Renacidin for the initial treatment of vesical calculi in selected spinal cord injury patients. Many such stones will completely dissolve and others may be made softer or smaller, facilitating cystolitholopaxy. A significant number of patients will be spared the inconvenience, cost and morbidity of hospitalisation for a surgical procedure.
