Abstract
Acetohydroxamic acid was administered in 5 patients to determine its effect in reducing urinary catheter incrustations. All patients had chronic indwelling catheters that required frequent changes because of severe incrustations and catheter occlusion. Incrustations were analyzed chemically for Ca, Mg, ammonia nitrogen and P. The degree of incrustation before and during acetohydroxamic acid therapy was compared in each patient and was decreased significantly (average 81%) during therapy (P < 0.05). Catheter changes were required frequently during therapy in all patients. Acetohydroxamic acid is effective in preventing catheter incrustations and should be considered in patients with this problem.
