Study Notes

Retrograde Pyelogram

May be performed concurrently with cystoscopy.
Identifies obstructions in kidneys or ureters.
Contrast dye is injected through catheter for X-ray visualization.
Stents can be inserted to maintain patency.

Ureter Stent and Placement

Used to ensure urine flow from the kidney to the bladder.

Ureteroscopy/Urethroscopy

Endoscopic procedures aimed at removing stones from the urethra, ureter, or kidney.
Ureteroscope is advanced via the urethra to the stone location.
Small stones can be removed using a stone basket; larger stones may require lithotripsy for fragmentation.

Pyelolithotomy

Open surgical procedure to extract stones in the renal pelvis.
Employs Randal stone forceps for stone removal.
Lithotripsy can also be performed laparoscopically.

Laser Lithotripsy

Noninvasive treatment for large kidney stones under X-ray guidance.
Utilizes lasers (Ho:YAG, Er:YAG, Nd:YAG) to fragment stones.
Normal saline is used for continuous irrigation during the procedure.

Transurethral Resection of the Prostate (TURP)

Surgical removal of part of the prostate gland, preserving the capsule.
Alleviates symptoms of Benign Prostatic Hyperplasia (BPH) and benign tumors.
Involves resectoscope passed through urethra, cutting loop electrode is used to cauterize tissue.

Procedural Considerations

Monitor for hyponatremia and signs of fluid overload due to irrigation fluid absorption.
Anesthesia and proper positioning are critical for safety and efficacy.

Anatomy - Kidneys

Positioned retroperitoneally, filtering blood to remove waste.
Blood supply derives from renal arteries (off the aorta) and drains through renal veins.
Right kidney is smaller and lower due to liver placement.

Anatomy - Adrenal Glands

Located atop the kidneys, these endocrine glands secrete epinephrine and various steroids.
Blood supply comes from arterial branches of the inferior phrenic artery and renal arteries.

Anatomy - Ureters

Extend from renal pelvis to the bladder at 25-30 cm length.
Propels urine to bladder through peristalsis.

Anatomy - Bladder

Serves as a urine reservoir until voided.
Supplied by superior and inferior vesical arteries; veins drain into internal iliac vein.

Anatomy - Urethra

Male urethra ranges from 20-25 cm; female urethra is about 4 cm long.

Anatomy - Prostate Gland

Surrounds the urethra at the bladder neck, divided into four regions.
Blood supply comes from the pudendal and inferior vesical arteries.

Male Reproductive Organs

Paired organs: testes, epididymis, vas deferens, Cowper's glands.
Singular organs: penis and scrotum.

Perioperative Nursing Considerations

Use of appropriate anesthesia and sterile irrigation fluids is vital.
Instrumentation varies based on procedure type.

Instrumentation and Equipment

Basic laparotomy set includes specialized instruments for prostate, bladder, and kidney surgeries.
Lasers require specific precautions for safety including signage and protective eyewear.

Irrigation Fluids

Normal saline is often used for observational interventions like cystoscopy and with lasers.
Sterile water with minimal absorption and non-electrolytic solutions are reserved for specific cautery procedures.

Surgical Interventions

Closed GU surgeries include cystoscopy, ureteroscopy, and laser lithotripsy.
Open GU surgeries include prostatectomy, cystectomy, pyelolithotomy, and nephrectomy.

Cystoscopy

Endoscopic procedure to examine the lower urinary tract.
Involves rigid and flexible scopes targeted at assessing the urethra, bladder, and prostate.

Resectoscope and TUR Procedures

Resectoscope is utilized for TURP and TURBT to remove excessive prostate or bladder tissue, with samples sent for pathology.

Prostatectomy Approaches

Simple Retropubic: Excellent exposure; less bleeding.
Suprapubic: Harder control of bleeding; accesses bladder.
Nerve Sparing: Maintains erectile function by preserving important nerves.

Testicular Surgeries

Orchidopexy is performed for undescended testicle in pediatric patients.
Testicular torsion requires emergency surgery to prevent testicle loss due to blood supply compromise.
