SPC insertion provides urinary drainage when urethral catheterisation is not possible or contraindicated. It can be done emergently for urinary retention or electively.
Indications
- Acute urinary retention with failed urethral catheterisation

- Long-term bladder drainage
- Post-urological surgery
Contraindications
- Distended bladder not palpable or visualised on ultrasound
- Suspected bladder carcinoma
- Pelvic trauma with possible bladder rupture
- Coagulopathy

- Small incision: 0.5–1cm (2–3cm above pubic symphysis).
- Trocar insertion or blunt dissection: Advance catheter into bladder.
