The prophylactic use of ureteral catheters during colorectal operations

Abstract

The necessity for preoperative ureteral catheter insertion for colorectal operations continues to be controversial. To determine our experience and what complications might be associated with ureteral catheter use, the charts of all patients in our department undergoing ureteral catheterization in combination with colorectal procedures between the years 1978 and 1989 were reviewed. The indications for operation, the presence or absence of urinary tract symptoms, and intravenous pyelogram findings (if performed) were recorded. Time for the procedure, size and number of catheters, and complications were noted. From the operative report, a retrospective grading of necessity for ureteral catheterization was assessed according to a scale from A to D. There were 120 ureteral catheterizations performed, bilaterally in 60 per cent of cases. Complications included renal colic (1), oliguria (1), and anuria (2). Intraoperatively, one ureter was cut and one ureter tied but recognized by palpation and ligature removed. Retrospective grading deemed ureteral catheterization necessary in 27.5 per cent of cases. We conclude that catheters are helpful in selected cases. For patients with bilateral catheter insertion, complications can be reduced by ensuring urine output prior to removal of the second catheter.
