Hydroceles (and hernias)
Adult hydrocelectomy
- Position supine, trim hair, prep/drape, give cefazolin or other antibiotic for skin flora
- Can make either midline incision along scrotal raphe or transverse incision through rugae
- Pick up layers and divide with electrocautery to avoid accidentally entering hydrocele too early, can also push testis anteriorly within scrotum to help identify layers
- Once overlying layers freed, can deliver testis + hydrocele into operative field
- May have further overlying layers, can bluntly push off with raytec or divide with electrocautery
- Once ready, open hydrocele anteriorly in longitudinal fashion to avoid testis and cord structures (epididymis and vas can travel within vaginalis)
- Can trim excess sac, obtain hemostasis, then wrap posterior to testis and loosely close posteriorly with running 3-0 vicryl
- If desired can pexy testis into scrotum with prolene or PDS (not done frequently)
- Replace testis back into scrotum, ensure good placement without torsion
- Close dartos with 3-0 vicryl, close skin with chromic or monocryl, then apply bacitracin
Pediatric hydrocelectomy + hernia repair
- Place patient supine, prep/drape, no antibiotics if prepubertal, perform ilioinguinal block
- Make inguinal incision ~3-5cm length starting just superior to pubic tubercle, dissect layers with electrocautery and bluntly divide with hemostat
- Define the inguinal canal then open external ring sharply with tenotomy scissors
- Grasp edges of fascia and bluntly pull canal contents off the fascia
- Gently grasp contents to identify hernia sac in canal, then push off other contents bluntly to isolate hernia sac
- Once hernia sac completely free, clamp with hemostat x2, divide between
- Dissect contents off proximal hernia sac, then twist and suture ligate with 3-0 vicryl
- Put traction on distal hernia sac, bluntly separating from surrounding scrotal dartos tissue (should eventually deliver testicle into field)
- Open hydrocele sac anteriorly to minimize injury to testicular/cord structures, can excise excess sac, pexy posterior to testis without strangulating with 3-0 vicryl interrupted
- Pull on scrotum to position testis back in scrotum, should sit comfortably without torsion
- Close external fascia with running 3-0 vicryl, close scarpa fascia with 3-0 vicryl interrupted, inject local anesthesia under skin, then close skin with 5-0 monocryl, then apply dermabond
Hydrocele aspiration
- Prep scrotum with betadyne, drape with sterile towels
- Inject lidocaine subcutaneously (usually 1-2mL sufficient)
- Insert large bore angiocath through scrotum, retract needle to leave cannula in place
- Aspirate with 50-60mL syringe until hydrocele completely drained
- Optional: use extension tubing and 3-way stopcock to make drainage more efficient
- Optional sclerotherapy: inject 200mg or 400mg (for > 500mL hydrocele) doxycycline in 10mL 0.5% bupivicaine (usually perform cord block prior due to pain), massage in for 1-2min - can also use alcohol or other chemicals
- Can apply dressing, send with pain meds and short course antibiotics
