“…This study found that smaller stones were more likely to pass spontaneously when compared to larger stones (<5 mm 486/551 [87%], >5 mm 814/1,093 [75%]). These findings are similar to stones in other points of the urinary tract as Shah et al [6] recently demonstrated. One of our included studies concluded that stones were 3 times more likely to pass spontaneously if they were situated at the ureterovesical junction as opposed to any other part of the distal ureter [13].…”

“…A large, international, retrospective cohort study recently noted that distal ureteric stones are significantly more likely to pass with conservative management alone compared to stones situated more proximally in the ureter [6]. However, when counselling patients to trial conservative management of their stone, it is crucial to understand the natural history of these patients with respect to the time frame they can be observed for before attempting other interventions.…”

Likelihood of Distal Ureteric Calculi to Pass Spontaneously: Systematic Review and Cumulative Analysis of the Placebo Arm of Randomized-Controlled Trials

Introduction: Distal ureteric calculi remain a widely debated topic without clear consensus on expectant management. This systematic review aims to assess the placebo arms of RCTs to extrapolate data on the natural history of distal ureteral stones and ascertain the success rate of expectant management. Methods: A literature search was performed, and 3 reviewers used a predefined inclusion criterion to independently select articles for inclusion. A cumulative analysis was undertaken, and risk of bias assessed using the Cochrane tool. Results: Stone expulsion was recorded in 1,823/2,447 (74.5%) patients overall. The expulsion rate of study participants receiving placebo varied widely from 35.2 to 88.9%. The overall expulsion rate of stones ≤5 mm was 486/561 (87%) as opposed to 814/1,093 (75%) in stones >5 mm in size. Time to stone expulsion varied from 8.54 to 24.5 days. A re rate of 2% was reported. Conclusions: Spontaneous passage of distal ureteric calculi is dependent on stone size and location within the ureter. Provided a patient does not portray symptoms of uncontrollable pain, infection, obstruction, or declining renal function, it is reasonable to trial a period of expectant management. Follow-up should be arranged to ensure symptom resolution, and alternative treatment can be offered if required.

“…Urinary stones are a group of diseases that occupy the agenda of the medical world with both their frequency and high recurrence rates. 1 Over the last 60 years, great strides have been made in urinary stone treatment, and in the previous two decades, endoscopic surgeries have taken the lead in treatment. 2,3 Ureterorenoscopy (URS) and flexible ureterorenoscopy (fURS) are commonly used surgical methods in ureter stone treatment.…”

Aims: Today, we have technology to break up a ureter stone in ureter as well as in renal pelvis during ureterorenoscopic procedures. In the past, when this option was not available, the surgeons improved several techniques and antiretropulsion devices in order not to let the stone migrate through renal pelvis. However, we still do not know whether it is advantageous to dust a stone in ureter where it is impacted or in a wider area such as renal pelvis. This study was carried out to clarify whether it is advantageous to breaking an upper ureter stone up where it is enclaved or in a wider area such as renal pelvis. Study Design: The data of 134 patients who underwent semirigid ureterorenoscopy (srURS) due to single and primary upper ureteral stones were included in our study and analyzed retrospectively. The patients were divided into two groups according to the development of spontaneous push-up during surgery (Group 1: non-push-up group, Group 2: push-up group). Results: Laboratory findings were changed significantly in both groups before and after surgery. However, this change was not significant between the groups. Operation times were statistically similar in both groups in contrast with the literature. Stone-free rates were significantly higher in srURS than in flexible ureterorenoscopy (fURS) (p<0,05). Complication rates were also found similar in this study. Conclusion: The application of srURS after fixing an upper ureter stone at its location using a Stone Cone® results in higher stone-free rates than pushing it back in order to dust it in renal pelvis. We recommend srURS supported by an antiretropulsion method as a treatment for upper ureteral stones.

Factors associated with spontaneous stone passage in a contemporary cohort of patients presenting with acute ureteric colic: results from the Multi‐centre cohort study evaluating the role of Inflammatory Markers In patients presenting with acute ureteric Colic (MIMIC) study

Abstract: stone size from a large contemporary cohort adjusting for key potential confounders. We anticipate that these data will aid clinicians managing patients with acute ureteric colic and help guide management decisions and the need for intervention.
