Match each gynecologic surgical procedure or specific operative step with the anatomical structure most at risk of iatrogenic injury during that intervention.
- Clamping and transection of the suspensory ligament of the ovary (infundibulopelvic ligament) during an oophorectomyUreter (at the pelvic brim, anterior to the iliac artery bifurcation)
- Ligation of the uterine vessels at the level of the internal cervical os during a hysterectomyUreter (at the cardinal ligament, crossing inferior to the uterine artery)
- Sharp dissection of the vesicouterine fold to create a bladder flap in a patient with a history of three cesarean deliveriesBladder (posterior wall or dome)
- Suture placement into the sacrospinous ligament during an apical vaginal vault prolapse repairPudendal nerve and internal pudendal vessels
- Blind passage of trocar needles behind the pubic symphysis during a retropubic tension-free vaginal tape (TVT) procedureBladder, bowel, or vascular structures (in the space of Retzius)
Cevap
Infundibulopelvic ligament ligation risks the ureter at the pelvic brim. Uterine vessel ligation risks the ureter at the cardinal ligament. Vesicouterine fold dissection risks the bladder. Sacrospinous ligament fixation risks the pudendal nerve. Retropubic sling placement risks structures in the space of Retzius.
Correct mapping requires recognizing the exact three-dimensional relationships in the female pelvis. Each surgical step threatens a distinct structure based on proximity. The ureter has two classic danger zones: the pelvic brim (ovarian vessels) and the internal cervical os (uterine vessels). Anterior compartment dissections risk the bladder, particularly the dome or posterior wall when adhesions are present. Vault suspensions risk the deep pelvic neurovasculature (pudendal bundle), and retropubic passages risk the organs traversing the space of Retzius.
