[Urinary calculi. Current role of in situ dissolution]

Area of Science:

• Urology
• Nephrology

Background:

• Urinary calculi pose significant clinical challenges.
• Management of complex stones, such as bilateral urate calculus or recurrent staghorn calculus, can be difficult.

Observation:

• Two patients with complex urinary stones were treated.
• One patient presented with bilateral urate calculus and anuria.
• The second patient had recurrent staghorn calculus.

Findings:

• Percutaneous nephrostomy stents were successfully installed in both patients.
• Urinary stones were dissolved in situ using irrigation.
• This approach demonstrated effectiveness in managing complex stone burdens.

Implications:

• Urinary stone dissolution in situ is a viable and advantageous treatment option.
• Minimally invasive techniques like percutaneous nephrostomy and irrigation can resolve complex urinary calculi.
• This method offers a potential solution for anuria and recurrent stone formation.
