Hemiacidrin irrigation in the management of struvite calculi: long-term results

Abstract

Renacidin (10 per cent hemiacidrin) irrigation has been used in the management of renal struvite calculi in 25 patients. Of these patients 22 were free of stone after irrigation: 16 after dissolution of residual stone fragments postoperatively, 4 after prophylactic postoperative irrigation and 2 after primary, nonsurgical percutaneous dissolution. Recurrent urinary tract infections owing to the original urease-producing bacteria occurred in 14 per cent of these patients and recurrent nephrolithiasis occurred in 9 per cent during an average followup period of 66 months.
