Surgical Principles

Reconstructive frameworks and universal operative technique. Organized into two groups: plastic surgery principles that govern when and why to reconstruct, and general surgical technique applicable to any surgical discipline. Domain-specific GU reconstruction principles (urethral, bladder, urinary diversion, upper tract, genital, fistula, prolapse) live with their respective sections in the Treatment Atlas.

Plastic Surgery Principles​

The reconstructive-thinking layer. When to reconstruct, how tissue heals, which ladder rung applies, and the tissue-transfer toolkit common to any reconstructive surgeon.

  • Plastic Surgery PrinciplesCore plastic-surgery tenets — the reconstructive mindset, tissue handling, atraumatic technique, planning the scar, and the plastic-surgeon's approach to defect coverage.
  • Reconstructive LadderThe ladder of reconstructive complexity — secondary intention → primary closure → skin graft → local flap → regional flap → free tissue transfer — applied to GU defects.
  • Wound HealingPhases of healing, factors that impair healing (diabetes, steroids, radiation, nutrition), and what each phase means for suture strength-retention and timing of subsequent reconstruction.
  • Wound Healing AdjunctsTissue adhesives (Dermabond, Prineo), donor-site dressings, NPWT / wound VAC, closed-incision NPWT, skin substitutes and ADMs (Integra, AlloDerm, Apligraf), PRP and growth factors, hyperbaric oxygen.
  • Flaps in GU ReconstructionGracilis, VRAM, peritoneal, vastus lateralis, omental, and others — vascularized-tissue transfer for urinary diversion, fistula repair, perineal reconstruction, and prosthetic coverage.
  • Grafts in GU ReconstructionBuccal, lingual, labial mucosa, intestinal segments, penile-preputial skin, saphenous vein, posterior auricular, STSG, FTSG, bladder mucosa — non-vascularized tissue transfer.
  • Radiation & Tissue EffectsAcute vs chronic radiation changes, the altered biology of the irradiated pelvis, and the implications for fistula repair, urethroplasty, reimplant, and any reconstruction in previously radiated tissue.

General Surgical Technique​

Universal operative technique applicable to any surgical discipline. Needles, sutures, incisions, closure patterns, bowel anastomosis, and the hand-economy that underpins them all.

  • Operative ExposureVaginal, perineal, and abdominal exposure by target — positioning, incisions, tissue-plane dissection, Kocher / Mattox / Cattell–Braasch visceral rotations, transmesenteric approaches, and the zone-based retroperitoneal algorithm in trauma.
  • Vascular Management & Damage ControlThe three-phase DCS paradigm and damage-control resuscitation. Vaginal / perineal packing, the pelvic-hemorrhage algorithm (binder → PPP → angioembolization → IIAL), REBOA zones, proximal aortic control, temporary intravascular shunts, and vessel-by-vessel repair-vs-ligation decisions.
  • Incisions & ClosureThe incision atlas (midline, Pfannenstiel, Gibson, flank, Chevron, thoracoabdominal, dorsal lumbotomy, perineal), fascial closure, layered vs mass closure, and modern evidence on small-bites fascial technique.
  • NeedlesNeedle anatomy — cutting vs reverse-cutting vs taper vs blunt-taper vs taper-cut tips — and needle-size selection by tissue.
  • SuturesMaterials and selection — absorbable vs non-absorbable, monofilament vs multifilament, strength retention, knot security, and a procedure-by-procedure selection table for GU reconstruction.
  • Barbed SuturesDedicated deep-dive — V-Loc, Quill, Stratafix, MONOFIX biomechanics; the upper-tract pyeloplasty controversy (Liatsikos 83% / Radford 40% failure); overtightening-to-avoid technique; SBO risk from exposed tails; clinical decision framework.
  • Bowel AnastomosisHand-sewn and stapled anastomosis configurations (end-to-end, end-to-side, functional end-to-end / GIA-stapled), single- vs double-layer, and the anastomotic-leak-risk factors relevant to urinary diversion with bowel.
  • Surgical ErgonomicsOR-table height, monitor placement, loupes, foot-pedal workflow, and the posture economics that determine whether a 6-hour case leaves the surgeon with a functioning neck and back.

A handful of named, eponymous stitches — Heaney, Quilting, Parker-Kerr — live as standalone reference pages, linked from the operational pages where they are used.
