How would you repair a ureteral injury < 5cm from the UVJ?
Ureteroneocystotomy (re-implant into the bladder)

- Consider Psoas Hitch, Baori flap, or mobilizing bladder
Transureteroureterostomy (implant to contralateral ureter)
Always place a drain to avoid urinoma

Percutaneous nephrostomy
What are the steps of repairing a bowel injury?
- Run the bowel first to identify other areas of injury

- Use 3-0 non absorbable for muscualris/serosa

5cm above the pubic symphysis
Blunt dissection
Associated with less fever, pain, blood loss, op time
What characterizes a Cherney incision?
Separate the rectus tendon from the pubic symphysis to visualize the space of Retzius
What characterizes a Maylard incision?
Transect the rectus muscle with ligation of the inferior epigastrics. No separation of rectus from sheath.
What characterizes a mass closure?
Incorporating the subcutaneous tissue, rectus, rectus sheath, fascia, and peritoneum in one bite
What characterizes a Smead-Jones mass closure?
Vertical mattress mass closure with double loop, then,
incorporate medical edge of sheath in a single loop
What are some factors necessitating mass closure?
Age, obesity, poor nutrition, steroids, radiotherapy, chemotherapy, any chronic condition leading to weak tissue
