title: Urethral catheterization in spinal surgery: a randomized prospective study.
abstract: In a prospective randomized study the effect of the use of an intraoperative indwelling urethral catheter (IUC) on urinary complications was investigated in patients undergoing spinal fusion. Two groups were formed; 16 patients received an intraoperative IUC and 16 patients had no intraoperative catheter (NC). All patients were, if necessary, intermittently catheterized in the postoperative period. Seven of the patients in the IUC group had positive cultures, defined as > or = 100,000 CFU/ml, compared with two patients in the NC group (n.s.). Another four patients in the NC group had cultures > or =10000 CFU/ml. Thirteen patients in the IUC group and 14 patients in the NC group had positive dip slides. The largest received urine volume in each patient at one intermittent catheterization did not differ significantly between the groups. However, in three patients in the NC group the volumes exceeded 1000 ml. Thus, irrespective of treatment dip slides showed bacteriuria in 84% of the patients. Perioperative indwelling catheters do not seem to cause many more infection complications than no bladder drainage during surgery, and the advantages of reduced risk of bladder distension injury and more accurate monitoring of fluid balance suggest their use.
