Urinary neutrophil gelatinase-associated lipocalin as a biomarker to monitor renal function in patients with obstructive ureteral calculi.
Qian S, et al. World J Urol 2019. PMID 30251051
METHODS: A cohort of 89 first-visit patients with renal colic caused by unilateral ureteral calculi were retrospectively reviewed. 46 of which received double-J ureteral stent placement (group 1) and the remaining 43 treated conservatively with analgesics and hydration (group 2) when diagnosed. ...And double-J ureteral stent can be considered as a protective factor to renal function in patients with obstructive ureteral calculi presenting renal colic....

A Comparison of Urolithiasis in the Presence and Absence of Microscopic Hematuria in the Emergency Department
Mefford JM, et al. West J Emerg Med 2017. PMID 28611901 Free PMC article.
For ureteral stones 5 mm or larger, the incidence of moderate-to-severe hydronephrosis was 49%, whereas for ureteral calculi less than 5 mm in size, the incidence of moderate-to-severe hydronephrosis was 14% (p < 0.0001). ...Although the presence of hematuria on urinalysis is a moderately sensitive screening test for urolithiasis, these results suggest patients without hematuria tend to have more clinically significant ureteral calculi, making their detection more important. ...

Factors Associated with Compliance in Submitting 24-Hour Urine Collections in an Underserved Community.
Ghiraldi EM, et al. J Endourol 2017. PMID 27931114
MATERIALS AND METHODS: A retrospective chart review of patients treated for kidney and/or ureteral stones between August 2014 and May 2016 was performed. ...RESULTS: A total of 193 patients met inclusion criteria for our study, 42.5% (82/193) of whom submitted 24-hour urine samples. ...

Value of Color Doppler ultrasound, kub and urinalysis in diagnosis of renal colic due to ureteral stones.
Abdel-Gawad M, et al. Int Braz J Urol 2014. PMID 25254610 Free article.
We attempted in this retrospective study to evaluate the accuracy of ultrasound (gray-scale and color Doppler with twinkling), KUB and urinalysis in diagnosis of renal colic due to ureteral calculi presented in Emergency Room. ...RESULTS: Renal and ureteral ultrasound (gray-scale) alone detected ureteral calculi in 615 cases (65.4%) and after utilizing Color Doppler Ultrasound with twinkling the diagnosis was made with confidence in 935 cases (99.6%) but 4 (0.4%). ...

Early term effect of ureterorenoscopy (URS) on the Kidney: research measuring NGAL, KIM-1, FABP and CYS C levels in urine.
Benli E, et al. Int Braz J Urol 2017. PMID 28792192 Free PMC article.
Urine samples were collected 5 times; before the URS procedure (control) and at 1, 3, 5 and 12 hours following the procedure. NGAL, KIM-1, FBAP and Cys C levels were measured in urine and compared with the control values. RESULTS: The NGAL levels in urine before the procedure and at 1, 3, 5 and 12 hours after the procedure were 34.59±35.34; 62.72±142.32; 47.15±104.48; 45.23±163.16 and 44.99±60.79ng/mL, respectively (p=0.001). ...

Derivation of decision rules to predict clinically important outcomes in acute flank pain patients
Wang RC, et al. Am J Emerg Med 2017. PMID 28082160 Free PMC article.
Clinically important outcomes were defined as inpatient admission for ureteral stones and alternative diagnoses. Clinically important stones were defined as stones requiring urologic intervention. ...

Imaging protocol for suspected ureteric calculi in patients presenting to the emergency department.
Hall TC, et al. Clin Radiol 2015. PMID 25529182
The overall positive rate for calculi was 45.4%, with an alternative diagnosis in 14.4%. Of the patients scanned with haematuria 49.36% were positive. ...This review suggests that in males a negative urine dipstick should not preclude CT investigation for renal colic in the presence of a "classical" history. ...

Haematuria in the diagnosis of urinary calculi.
Ooi SB, et al. Ann Acad Med Singapore 1998. PMID 9663312
The aims of this study were to compare the sensitivity of urine dipstix (Combur 9 test) versus urine microscopy in detecting haematuria and to determine the proportion of patients with renal or ureteric colic due to urinary calculi who have haematuria. ...Telephone interviews were done to determine whether any calculi had been passed. Urine dipstix detected haematuria in 95.4% [95% confidence intervals (CI) 87.1% to 100.0%] of patients with urinary calculi, whilst urine microscopy detected haematuria in 70.8% (95% CI 58.2% to 92.6%). ...

Microscopic hematuria and calculus-related ureteral obstruction.
Stewart DP, et al. J Emerg Med 1990. PMID 2096163
The evaluation of patients with ureteral calculi in the emergency department has historically included urinalysis (UA) and intravenous pyelograms (IVP). ...Urine red blood cells were recorded as less than 3 rbc/hpf (negative) or greater than or equal to 3 rbc/hpf (positive). IVPs were recorded as nonsevere or severe. ...
