Case report of bilateral penetrating renal trauma caused by a wooden stick

RATIONALE: Kidney is the most frequently injured organ of the genitourinary system during trauma. Bilateral penetrating renal trauma (BPRT) is extremely rare and sporadically reported in the previous literature. Here, we reported a unique case of BPRT. PATIENT CONCERNS: A 43-year-old man, with no medical history, was accidentally penetrated by a wooden stick and presented with sharp pain in the left flank. DIAGNOSIS: Laboratory tests revealed microscopic hematuria, mildly elevated leucocyte and amylase, normal hemoglobin (145 g/L) and creatinine (1.05 mg/dl). Computed tomography demonstrated bilateral penetrating renal injuries with perinephric/subcapsular hematoma, fracture of the second lumbar vertebra and 10th rib. INTERVENTIONS: An emergency exploratory laparotomy was executed immediately. According to the American Association for the Surgery of Trauma Organ Injury Scale grading system, grade V and III injuries were considered for the left and right kidney, respectively. Nephrectomy and renorrhaphy were performed on the left and right kidney, respectively. OUTCOMES: The postoperative course was uneventful. Eleven days after the surgery, the patient discharged with no complications. LESSONS: We present a rare and challenging case which was handled successfully, and it may provide useful information for the management of BPRT.
