Summary
Ureteric colic stone size significantly impacts spontaneous passage rates. Stones 5 mm or less have a 92% chance of passing, while larger stones have only a 28% chance, influencing treatment decisions.
Area of Science:
- Urology
- Nephrology
- Surgical Management
Background:
- Ureteric colic is a common condition caused by stones in the ureter.
- Management strategies aim to facilitate stone passage and alleviate pain.
- Stone size and location are critical factors influencing treatment outcomes.
Purpose of the Study:
- To analyze the relationship between ureteric stone size/position and management outcomes.
- To evaluate the effectiveness of spontaneous passage versus surgical intervention.
- To assess the role of endoscopic procedures in ureteric stone management.
Main Methods:
- Retrospective analysis of 134 patients with ureteric colic (1985).
- Categorization of stones by size (≤5 mm vs. ≥6 mm) and position.
- Documentation of spontaneous passage rates and surgical interventions (endoscopic, open).
Main Results:
- Spontaneous stone passage occurred in 100 patients (75%).
- Stones ≤5 mm had a 92% spontaneous passage rate; stones ≥6 mm had a 28% rate.
- Surgical intervention was required for 34 patients, with endoscopic procedures being common.
Conclusions:
- Stone size is a primary determinant of spontaneous passage in ureteric colic.
- High spontaneous passage rates emphasize conservative management for smaller stones.
- Endoscopic interventions should be considered judiciously, especially for larger or persistent stones.
