“…41,42 A retrospective review of association between calculus location and symptoms demonstrated that 17% of calyceal stones were associated with pain/symptoms. 43 Passage of a ureteral calculus depends on size and location, with a spontaneous passage rate of 48% for proximal versus 75% for distal ureteral calculi and 76%, 60%, 48%, and 25% for 2 to 4, 5 to 7, 7 to 9, and greater than 9 mm diameter, respectively. 29,44 a-Blocker therapy (most commonly tamsulosin) has been shown to improve passage rates by 25%.…”

Abstract Background This systematic review and meta-analysis aims to investigate the prevalence of microhematuria in patients presenting with suspected acute renal colic and/or confirmed urolithiasis at the emergency department. Methods A comprehensive literature search was conducted to find relevant data on prevalence of microhematuria in patients with suspected acute renal colic and/or confirmed urolithiasis. Data from each study regarding study design, patient characteristics and prevalence of microhematuria were retrieved. A random effect-model was used for the pooled analyses. Results Forty-nine articles including 15’860 patients were selected through the literature search. The pooled microhematuria prevalence was 77% (95%CI: 73-80%) and 84% (95%CI: 80-87%) for suspected acute renal colic and confirmed urolithiasis, respectively. This proportion was much higher when the dipstick was used as diagnostic test (80% and 90% for acute renal colic and urolithiasis, respectively) compared to the microscopic urinalysis (74% and 78% for acute renal colic and urolithiasis, respectively). Conclusions This meta-analysis revealed a high prevalence of microhematuria in patients with acute renal colic (77%), including those with confirmed urolithiasis (84%). Intending this prevalence as sensitivity, we reached moderate values, which make microhematuria alone a poor diagnostic test for acute renal colic or urolithiasis. Microhematuria could possibly still important to assess the risk in patients with renal colic.
