    Study Notes

    Retrograde Pyelogram

    • Performed concurrently with cystoscopy to identify kidney or ureteral blockages.
    • Contrast dye is injected through ureters via catheter for X-ray visualization.
    • Stents may be placed to maintain urinary tract patency.

    Ureteroscopy/Urethroscopy

    • Endoscopic procedures designed to remove stones from the urethra, ureter, or kidney.
    • Ureteroscope advances through the urethra, bladder, and into the ureter to locate stones.
    • Small stones can be snared; larger stones are treated with Lithotripsy to fragment them.

    Pyelolithotomy

    • An open surgical technique to extract stones from the renal pelvis.
    • May utilize Randal stone forceps for stone removal.
    • Can also be performed laparoscopically with lithotripsy.

    Laser Lithotripsy

    • A noninvasive approach for treating larger kidney stones using laser technology.
    • X-ray guidance assists in targeting stones.
    • Various lasers (Ho:YAG, Er:YAG, Nd:YAG) break stones into smaller fragments for easier excretion.
    • Continuous irrigation is maintained using normal saline.

    Transurethral Resection of the Prostate (TURP)

    • Surgical intervention involving the removal of prostate tissue to alleviate symptoms of benign prostatic hyperplasia (BPH).
    • Procedure involves using a resectoscope to cauterize and remove obstructive tissue.
    • Irrigation fluid carries resected tissue to the bladder, which is later flushed out through a catheter.

    Anatomy: Kidneys

    • Positioned retroperitoneally; they filter blood, removing waste products.
    • Blood supply derived from the renal artery, branches of the aorta.
    • The right kidney is smaller and situated lower due to liver placement.

    Anatomy: Adrenal Glands

    • Located atop the kidneys; they act as endocrine glands.
    • Medulla secretes adrenaline; the cortex produces hormones influenced by the pituitary gland.

    Anatomy: Ureters

    • Tubes extending from renal pelvis to bladder, approximately 25-30 cm long and 4-5 mm in diameter.
    • Function to propel urine via peristalsis.

    Anatomy: Bladder

    • Extraperitoneal in location, serves as a urine reservoir.
    • Supplied with blood from the superior and inferior vesical arteries; drains into the internal iliac vein.

    Anatomy: Urethra

    • Male urethra measures 20-25 cm while female urethra is only 4 cm long.

    Anatomy: Prostate Gland

    • Surrounds the urethra and is located at the bladder neck.
    • Divided into four glandular regions; vascular supply from the pudendal and inferior vesical arteries.

    Surgical Instrumentation

    • Basic laparotomy, prostate, bladder, and kidney-specific instruments are utilized.
    • Includes short and long instruments as well as retractors like the Bookwalter.

    Anesthesia and Positioning

    • General or local anesthesia may be employed depending on procedure type.
    • Positioning varies (e.g., supine, lithotomy) according to the surgical approach.

    Anesthesia Precautions

    • Monitor for signs of fluid overload and electrolyte imbalances especially during procedures involving irrigation.

    Irrigation Fluids

    • Normal saline is used for interventions like cystoscopy; sterile water for monopolar cautery.
    • Non-electrolytic solutions (e.g., Sorbitol, Glycine) should be used to minimize blood absorption risks.

    Surgical Interventions: Closed vs. Open GU Surgery

    • Closed: Cystoscopy, ureteroscopy, laser lithotripsy.
    • Open: Prostatectomy, cystectomy, pyelolithotomy, and nephrectomy.

    Orchidopexy

    • Surgical procedure aimed at repositioning an undescended testicle into the scrotum, mainly in pediatric patients.

    Testicular Torsion

    • An emergency condition characterized by twisted spermatic cord leading to compromised blood supply.
    • Requires immediate surgical intervention to prevent testicular loss.
