Abstract：
Renal angiomyolipoma (rAML) is a rare benign tumour primarily affecting women due to hormonal influences, with accelerated growth observed during pregnancy. This case report presents a multigravida woman in her mid-20s at 37 weeks of gestation with stable vital signs and normal physical examination findings, except for swelling in the lower extremities. Following caesarean section delivery, she developed flank pain and haematuria in the immediate postoperative period. Emergency surgery revealed a ruptured rAML, resulting in unstable haemodynamics and significant blood loss. A multidisciplinary team performed a left radical nephrectomy to control bleeding. The patient required transfusions, ventilation and postoperative antibiotic therapy. This case underscores the importance of considering rAML rupture in the immediate postoperative period following caesarean section, highlighting the need for prompt evaluation in pregnant women with a history of urologic disorders.
摘要：
肾血管平滑肌脂肪瘤（rAML）是一种罕见的良性肿瘤，主要由于激素的影响而影响女性，在怀孕期间观察到加速的生长。该病例报告介绍了一名妊娠37周时20多岁的多胎妇女，其生命体征稳定，体检结果正常。除了下肢肿胀.剖腹产后，术后即刻出现腰痛和血尿。急诊手术显示rAML破裂,导致血液动力学不稳定和大量失血。一个多学科小组进行了左根治性肾切除术以控制出血。病人需要输血,通气和术后抗生素治疗。此病例强调了在剖腹产后立即考虑rAML破裂的重要性，强调有泌尿系统疾病史的孕妇需要及时评估。
