Hemiacidrin irrigation of the renal collection system via nephrostomy for the dissolution of residual postoperative calculi is described in 14 cases. The irrigation successfully dissolved 13 to 16 caliceal calculi. It did not dissolve any parenchymal calcifications. No known stones of pure calcium o ~ r apatite have been dissolved. Residual stones can safely be dissolved with hem1ac1dnn irrigation via nephrostomy if~ar open drainage and scrupulously sterile urine are maintained. __ Residual renal calculi following pyelolithotomy for infected hemiacidrin infusion was begun.

change in the retained calculus. The creatinine level returned slowly to the preoperative level of 2.0 by 2 months postoperatively. No fever occurred in this patient during the entire postoperative course.

The minor complications included 3 transient temperature elevations as high as 100.6 degrees. The temperature elevations were treated with immediate cessation of the irrigation. Reculture of the nephrostomy urine to ascertain its continuing sterility was performed. After defervescence and the demonstration of a continuing sterile nephrostomy urine, the infusion was continued in 2 patients. In 1 patient a positive nephrostomy urine culture led to discontinuation of the infusion. Bladder irritability requiring transient Foley urethral catheterization or cessation of therapy occurred in 3 patients.
