Always Take Renal Colic Seriously: A Rare Complication of Renal Stone

Pelvis rupture secondary to renal colic is an exceptionally rare but severe complicationof nephrolithiasis. This case report describes a 32-year-old male who presentedwith intense flank pain, gross hematuria, and urinary obstruction. A computedtomography (CT) scan revealed a 3-mm calculus at the ureterovesical junction causinghydronephrosis and, notably, a rupture of the renal pelvis with urine extravasation intothe retroperitoneal space. Immediate intervention included ureteroscopic lithotripsy,stent placement, and antibiotic therapy, leading to symptom resolution and improvedrenal function. This report highlights the diagnostic challenges associated with pelvisrupture, which often mimics typical renal colic symptoms, and emphasizes the criticalrole of contrast-enhanced CT in detection. Prompt management is essential to preventcomplications such as sepsis and long-term renal damage. The case underscores theimportance of recognizing this rare entity to optimize patient outcomes and guidefuture clinical approaches to similar presentations.
