Study Notes
Genitourinary Surgery Overview
- Genitourinary (GU) anatomy includes critical components such as kidneys, adrenal glands, ureters, bladder, and reproductive organs.
- Surgical interventions for GU surgeries encompass procedures like scrotal surgery, prostate surgery, and kidney surgery.
Anatomy - Kidneys
- Positioned retroperitoneally; essential for removing urea and liquid waste from blood.
- Supplied by renal artery branching directly from the aorta; drainage occurs via the renal vein.
- Recognized as highly vascular organs; the right kidney is smaller and lower due to liver location.
Anatomy - Adrenal Glands
- Endocrine glands located atop the kidneys.
- Secretions include epinephrine (medulla) and various steroids and hormones (cortex), influenced by the pituitary gland.
- Blood is supplied by arterial branches from the inferior phrenic artery and renal arteries.
Anatomy - Ureters & Bladder
- Ureters extend from renal pelvis to bladder base, measuring 25-30 cm long and 4-5 mm in diameter.
- Function through peristalsis to propel urine to the bladder.
- Bladder serves as the urine reservoir and is located extraperitoneally; supplied by superior and inferior vesical arteries, draining into the internal iliac vein.
Urethra
- Male urethra length: 20-25 cm; Female urethra length: 4 cm.
Anatomy - Prostate Gland
- Located at bladder neck, surrounding the urethra, with four glandular regions encapsulated by a capsule.
- Blood supply from pudendal and inferior vesical arteries.
Male Reproductive Organs
- Paired organs include testes, epididymis, vas deferens, Cowper’s glands.
- Singular organs include the penis and scrotum.
Perioperative Nursing Considerations
- Key factors in perioperative care include anesthesia management, patient positioning, surgical count, blood replacement protocols, and appropriate choice of irrigation fluids.
Instrumentation and Equipment
- Basic laparotomy sets with short/long instruments for prostate and kidney procedures, large abdominal retractors, Foley catheters, cystoscopes, and resectoscopes.
- Lasers used include Holmium YAG and KTP Green Light; strict fire safety precautions are essential.
Irrigation Fluids
- Normal Saline: Used for observational interventions and compatible with lasers.
- Sterile Water: Utilized with monopolar cautery when absorption is minimal.
- Non-electrolytic mediums such as Sorbitol and Glycine are employed when absorption is expected.
Surgical Interventions - Comparison
- Closed GU Surgery examples: Cystoscopy, Ureteroscopy, Laser Lithotripsy, TURP (Transurethral Resection of Prostate), TURBT (Transurethral Resection of Bladder Tumor).
- Open GU Surgery examples: Prostatectomy, Cystectomy, Nephrectomy, Kidney Transplant.
Cystoscopy
- A procedure for examining lower urinary tracts using rigid or flexible scopes.
- Common indications include obstructive symptoms, with potential complications such as hypervolemia and hyponatremia.
Prostate Surgery Techniques
- Simple Retropubic Prostatectomy: Emphasizes good exposure and bleeding control through an abdominal incision.
- Suprapubic Prostatectomy: Access to the prostate through a low abdominal incision, with difficulties in controlling bleeding.
- Nerve Sparing Radical Prostatectomy: Aims to preserve erectile function by avoiding nerve damage.
Bladder Surgery
- Open radical cystectomy involves the removal of the bladder and adjacent structures.
- Creation of an ileal conduit diverts urine flow post-surgery using a segment of the ileum.
Kidney Surgery
- Nephrectomy is commonly performed through lateral positioning, utilizing flank or thoracoabdominal approaches.
- Laparoscopic nephrectomy offers shorter recovery times but typically involves longer surgical durations.
Kidney Transplant
- Indicated for patients with renal failure, involving the donor kidney's anastomosis to the recipient’s vasculature.
- Commonly performed laparoscopically, often necessitating two ORs for living donor procedures.
Orchidopexy
- Surgical correction of undescended testicles, primarily in pediatric patients, ensuring proper anatomical positioning.
Testicular Torsion
- A surgical emergency characterized by twisted spermatic cords threatening blood supply; immediate intervention is essential.
Conclusion
- Understanding GU anatomy and surgical procedures' nuances is vital for effective perioperative care and patient management.
