ㅤContext to the study:
Can you tell me about a study that explores the long-term outcomes of asymptomatic renal calculi?
ㅤ✅ Take-home message of study:
In men presenting with asymptomatic renal stones:
26% will need surgical treatment within 3 years
77% will have an increase in stone size, develop pain or need surgical treatment within 3 years
ㅤ Retrospective observational study
ㅤ
Study participants:
Number included: 300
Inclusion criteria:
Male
Patients with asymptomatic renal stones presenting from 1996 to 2001
ㅤ
ㅤ
Key study outcomes:
Mean follow-up: 3 years (rounded down from 3.26 years)
Need for surgical intervention (SWL or URS or PCNL) at 3-years: 26%
Disease progression (pain or stone growth or surgical intervention) at 3-years: 77%
Higher rates of disease progression were seen with larger stones (≥4mm); renal pelvis stones; patients with raised uric acid levels (serum and urine).
