Summary

Open stone surgery for urinary stones is rare, used for complex cases or when less invasive methods fail. This technique achieved a 90% stone-free rate with low morbidity in a retrospective study.

Area of Science:

  • Urology
  • Surgical Oncology

Background:

  • Urinary stone disease management has evolved, with a shift towards minimally invasive treatments.
  • Open stone surgery, once a primary modality, is now reserved for specific complex cases.

Purpose of the Study:

  • To review the indications, outcomes, and patient characteristics for open stone surgery.
  • To evaluate the role of open stone surgery in the context of contemporary urinary stone disease treatment.

Main Methods:

  • A 3-year retrospective study of urinary stone disease treatment modalities at Singapore General Hospital.
  • Analysis of patient demographics, stone burden, surgical factors, indications, and outcomes for open stone surgery cases.

Main Results:

  • Open stone surgery constituted 2% of procedures (n=50), including nephrolithotomies and ureterolithotomies.
  • Common indications included complex stone burden (38%), non-functioning kidneys (20%), and failure of minimally invasive treatments (16%).
  • A 90% stone-free rate was achieved with 8% morbidity, primarily wound infections and pneumothorax.

Conclusions:

  • Minimally invasive modalities are effective for most urinary tract calculi.
  • Open stone surgery remains a valuable option for select patients with complex stone burdens, failed prior treatments, or non-functioning kidneys.
