Trends and benefits of prophylactic ureter catheters in the era of minimally invasive surgery.

Background: The recent spike in ureter injury (UI) amidst the rise of minimally invasive surgery (MIS) has focused attention on the propriety of prophylactic ureter catheters (PUCs) for abdominopelvic operations.

Methods: A retrospective review of PUCs for rectal cancer resection following neoadjuvant therapy, combined with a comprehensive literature review.

Results: There were zero UI in the current study.

It is time to retire Goodsall's Rule: the Midline Rule is a more accurate predictor of the true and natural course of anal fistulas.

Background: On May 6, 1887 at a meeting of the West London Medico-Chirurgical Society, original observations attributed to D. H. Goodsall described an association between the secondary (external) sinus opening and the location of the primary (internal) opening of an anal fistula: posterior external sinuses had a midline origin and anterior external sinuses took a straight path to their internal origin-eponymously known as Goodsall's Rule.
