Summary
Outpatient ureteroscopy is effective, but subsequent pain and complications are linked to ureteral stenting. Selective stenting can minimize these risks, while unplanned admissions remain unpredictable.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Outpatient Procedures
Background:
- Outpatient ureteroscopy is a common procedure for treating urinary tract conditions.
- Identifying predictors of postoperative events is crucial for optimizing patient care and resource allocation.
Purpose of the Study:
- To identify risk factors predicting postoperative events after outpatient ureteroscopy.
- To analyze the relationship between patient/operative factors and outcomes such as pain, emesis, and complications.
Main Methods:
- Retrospective analysis of 329 patients undergoing outpatient ureteroscopy (1996-2000).
- Patient selection based on medical and social factors.
- Multivariate analysis to identify predictive factors for postoperative events including pain, emesis, and complications.
Main Results:
- High success rate (99.7%) for ureteroscopic access; 91% stone-free rate for ureteroscopic lithotripsy.
- Female patients reported more symptoms and emesis.
- Longer operative time (>60 min) correlated with higher day 1 pain.
- Ureteral stenting associated with increased day 3 pain and complication rates (16.8% vs 4%).
Conclusions:
- Outpatient ureteroscopy is a safe and effective procedure.
- Postoperative pain and complications are significantly influenced by ureteral stenting.
- Selective stenting strategies can potentially reduce subsequent pain and complications, while unplanned admissions could not be predicted.
