Description
Summary:	Renal forniceal rupture (FR) is a unique complication of obstructive uropathy. This study aimed to identify the predictors of FR among patients presenting with renal colic due to obstructing ureteral calculi. After obtaining ethics approval, electronic records of patients from three National Guard hospitals in Saudi Arabia were reviewed between 2016 and 2020 to identify patients who presented with renal colic and were diagnosed with FR due to obstructive ureteric stones (FR group). An equivalent number of consecutive patients presenting with renal colic due to obstructing ureteric stones without FR was selected as a control group (non-FR group). Patients were grouped according to age group (<30, 30-40, 41-50, and >50 years), body mass index (BMI) class, gender, comorbidities, grade of hydronephrosis, location of the stone in the ureter, size of the stone (<3 mm, 3-7 mm, and >7 mm), and stone former status. Baseline patients' and stone characteristics were compared, and a regression analysis was performed to identify predictors of FR. A total of 50 patients with FR were identified, and a control group of 50 patients without FR were selected. The baseline patients' and stone demographic characteristics in terms of age ( = 0.42), gender ( = 0.275), BMI ( = 0.672), comorbidity, grade of hydronephrosis ( = 0.201), and stone location ( = 0.639) were comparable between the FR group and the non-FR group. However, the stone size was statistically significant between both groups ( = 0.014). On multivariable analysis, it was found that the stone size was associated with a significantly higher increase in the incidence of FR (odds ratio [OR]: 6.5 [1.235-34.434]; = 0.027). Furthermore, the age group between 30 and 40 years was potentially at a lower risk for FR (OR: 0.262 [0.069-0.999]; = 0.049). This multicenter study showed that the stone size 3-7 mm had a six-fold increase in the chance of FR, and the age group between 30 and 40 years is potentially at a lower risk for FR.
