RESUMEN
Objective To explore the diagnosis and treatment for primitive neuroectodermal tumor of the adrenal gland.Methods The clinical data of 2 patients with primitive neuroectodermal tumor of the adrenal gland were retrospectively analyzed.Literatures about diagnosis and treatment of primitive neuroectodermal tumor arising from the adrenal gland were also reviewed.Results B type ultrasonography and computer tomography scans showed a cystic and solid soft tissue masses about 3 cm (patient 1) and 15 cm (patient 2) in maximum diameter with rough border.Surgeries were performed successfully in 2 patients.The diagnosis of primitive neuroectodermal tumor arising from the adrenal gland was confirmed by histopathology and immunohistochemistry.During follow up,evidences of tumor recurrence were not found in the first patient.However,the second patient had diffuse retroperitoneal lymph node metastasis 3 months after surgery.Then,the patient died 6 months after surgery.Conclusion The primitive neuroectodermal tumor of the adrenal gland is extremely rare with highly malignant and poor prognosis.Its diagnosis is based on histopathology and immunohistochemistry.Multimodal therapeutic regimens including surgery,combination with chemotherapy and radiotherapy were recommended.
RESUMEN
Objective To compare the effect of ureteroscopic pneumatic lithotripsy(URL) and extracorporeal shock wave lithotripsy(ESWL) for ureteral stones.Methods 90 patients with ureteral stones were randomly divided into group A( URL group),group B( ESWL group),each group 45 cases.The effect of surgical treatment was compared between the two groups.Results The one-time success rate of gravel,stone free after 4 weeks of A group was significantly higher than that of group B( x2 =9.680,5.414,all P ＜0.05),but there was no significant difference in the surgical time and hospital stay of the two groups( t =1.010,0.909,all P ＞ 0.05 ).The postoperative renal colic,fever and other complications of group A were significantly lower than that of group B ( x2 =6.049,5.075,all P ＜0.05),but the gross heraturia and ureteral injury of group A was higher than that of group B(x2 =5.874,3.873,all P ＜ 0.05 ).Conclusion The ureteroscopic pneumatic lithotripsy and extracorporeal shock wave lithotripsy in the treatment of ureteral stones all have good effect,but ureteroscopic pneumatic lithotripsy and stone rubble drain success rate are significantly higher than extracorporeal shock wave lithotripsy,and postoperative complications are relatively less than extracorporeal shock wave lithotripsy.
