Prophylactic ureteral catheterization in colon surgery. A five-year review

Area of Science:

• Urology
• Colorectal Surgery
• Surgical Safety

Background:

• Prophylactic ureteral catheter placement is common but debated in distal colon operations.
• Assessing the frequency, safety, and effectiveness of these catheters is crucial.

Purpose of the Study:

• To evaluate the use of prophylactic ureteral catheters during sigmoid and rectosigmoid colectomies.
• To determine the incidence of ureteral complications associated with their use.

Main Methods:

• Retrospective analysis of 561 patients undergoing sigmoid or rectosigmoid colectomy between 1986 and 1991.
• Data collected included patient demographics, diagnosis, colectomy type, ureteral catheter placement, and ureteral complications.

Main Results:

• Ureteral catheterization was performed in 16.4% of patients.
• The overall rate of ureteral injury was 0.71%, with 2.2% in the catheter group and 0.43% in the non-catheter group.
• The direct risk of ureteral injury from catheter insertion was 1.1%, with no incidence of reflux anuria when catheters were removed within 24 hours.

Conclusions:

• Prophylactic ureteral catheters were used in 16.4% of distal colectomies by experienced surgeons.
• While the 1.1% risk of ureteral injury is small, it is significant.
• These catheters do not guarantee prevention of ureteral injuries but can aid in their immediate detection.
