Results: A total of 18,474 patients had a resection for colorectal cancer. Eighty-two ureteral injuries were related to colorectal surgery. The rate of ureteral injuries in the entire cohort was 0.44 %, with 37 (0.59 %) injuries in the laparoscopic group (n = 6,291) and 45 (0.37 %) injuries in the open group (n = 12,183), (P = 0.03). No difference in ureteral injury was found in relation to surgical approach in colon cancer patients. In rectum cancer patients (n = 5,959), the laparoscopic approach was used in 1,899 patients, and 19 (1.00 %) had ureteral injuries, whereas 17 (0.42 %) of 4,060 patients who underwent an open resection had a ureteral injury. In multivariate analysis adjusted for age, gender, ASA score, BMI, tumor stage, preoperative chemo-radiation, calendar year, and specialty of the surgeon, the laparoscopic approach was associated with an increased risk of ureteral injury, OR = 2.67; 95 % CI 1.26-5.65.

Conclusion: In this nationwide study laparoscopic surgery for rectal cancer with curative intent was associated with a significantly increased risk of iatrogenic ureteral injury compared to open surgery.

Prophylactic Flomax for prevention of postoperative urinary retention

One discussion this week involved the use of prophylactic flomax in preventing postoperatuve urinary retention (POUR).


Reference: Ghuman A, et al. Prophylactic use of alpha-1 adrenergic blocking agents for prevention of postoperative urinary retention: A review & meta-analysis of randomized clinical trials. American Journal of Surgery. 2018 May;215(5):973-979. doi: 10.1016/j.amjsurg.2018.01.015. Epub 2018 Feb 3.

Summary: With an increase in outpatient and fast-track surgical procedures, urethral catheterization is used less commonly thus increasing the likelihood of POUR. Urethral catheterization, a mainstay of initial management for patients with POUR, can
be associated with prolonged length of hospital stay and complications, such as urinary tract infections that may increase cost of care.
