title: Simplified infusion method for 10% hemiacidrin irrigation of renal pelvis.
abstract: A variable pressure volumetric pump was used for 10% hemiacidrin irrigation of the renal pelvis in 7 renal units (6 patients) with struvite calculi after initial percutaneous debulking and extracorporeal shock-wave lithotripsy (ESWL). The pump provided a constant display of intrapelvic infusion pressure, and an alarm which signaled if a preset maximum infusion pressure was exceeded. Compared with standard open manometer monitoring of intrapelvic pressure, this closed system of irrigation eliminates the problems associated with time-consuming assembly and maintenance, irrigant spillage, and system contamination. At the completion of therapy, 5 renal units were completely stone-free while 2 had only minimal residual caliceal "dust." Complications were minor and few in number. We conclude that a variable pressure volumetric pump provides excellent clinical results and safely simplifies irrigation for percutaneous chemolysis of struvite calculi.
