- Dr Nicholas Rukin, Redcliffe Hospital
The urethra is a tube that drains urine from the bladder and can sometimes narrow due to injury and infection, known as urethral strictures. Passing increasing sized metal urethral sound dilators through male urethral strictures was the classical treatment for strictures. Although success rates are around 65%, these procedures are surgeon dependant and carry the risk of inadverted trauma to the delicate urethral membrane.
Most surgeons now use a Seldinger technique, with the Cook S-curve© dilators. These offer a safe, effective and reproducible dilatation of the stricture. These single use devices cost $650 per set and we estimate Metro North Hospitals spends over $100,000 per year on these. We aim to develop an alternative surgical equipment to treat these strictures.
- 3D printing of urethra model
- Designing of dilators for stricture treatment
To design a surgical device for treating urethral strictures with the following properties:
- complements the anatomy of the urethra to aid gradual dilatation of the stricture
- enables safe access to blood vessel and urethra
- easily reproducible
Skills and experience
Experience in 3D printing and designs are favourable.
