肾错构瘤破裂出血的诊治

目的：探讨肾错构瘤破裂出血的诊断治疗方法。方法：回顾分析1998-2004年诊治的14例肾错构瘤破裂出血患者的临床资料，14例患者均行B超及CT检查，4例行MRI检查，所有病例均行手术治疗。结果：14例术后病理诊断均为错构瘤，术前B超诊断符合率为28．6％，CT为71．4％，MRI为100％。术后随访6个月。2年，未见复发。结论：CT和MRI是诊断肾错构瘤破裂出血的可靠方法，可明确出血的范围，对于直径大于5cm的肿瘤应早期积极手术，手术治疗应尽可能地保留肾单位。

An review for diagnosing and treating renal hamartoma spontaneously ruptured

Objective To study the methods for diagnosis and treatment of renal hamartoma spontaneously ruptured.Methods Clinical data of 14 cases of renal hamartoma spontaneously ruptured were reviewed retrospectively from 1998 to 2004.All the patients were examined by ultrasonography.14 cases were examined by CT scanning,4 by MRI.Results Spontaneous rupture of renal hamartoma were confirmed in 10 of diagnosis by CT scanning,14 patients all underwent pathological examinations which confirmed the diagnosis of hamartoma.The concordance of B ultrasound,CT and MRI were 28.6%,71.4% and 100% respectively with the pathological finds. Surgical operations included 8 cases of nephromy,4 cases of partial nephrectomy and 2 cases of enucleation.Conclusion It is windly acceptble that CT and MRI is the best method of imaging examination which may confirm the character of the lesion and the range of bleeding.If the tumor exceeds 5 cm and grows nearby the capsule of kidney,active treatment should be considered.Any operative management should preserve the funcion nephrons as much as possible.
