Resection of a giant renal angiomyolipoma in a solitary kidney with preoperative arterial embolization / 中华医学杂志(英文版)

Renal angiomyolipoma is a type of benign tumor that occurs sporadically in addition to being associated with tuberous sclerosis. Preoperative embolization of large tumors is important to avoid excessive blood loss during surgery. We reported a patient with a 5505-g giant renal angiomyolipoma in a solitary kidney. The patient was treated with preoperative embolization and radical nephrectomy without complications. This type of treatment for an enormous angiomyolipoma can reduce the risk of uncontrolled hemorrhage caused by rupture of the tumor during the operation and should be considered for the treatment of similar tumors.

Clinical application of nerve stimulation in obturator nerve block during transurethral resection of the bladder tumor / 中华神经医学杂志

Objective To explore the feasibility and clinical eflfect of nerve stimulation in obturator nerve block during transurethral resection of the bladder tumor(TURBT). Methods Thirty superfcial bladder tumor patients were randomly divided into observation group and control group, with 15 patients in each group.The patients of observation group were punctured and injected under the guidance of nerve stimulator localization,and the ones in control group underwent conventional puncture and injection of drug.Comparison was done between the 2 groups in curative effect,used drug dose and post-operative life quality. Results One patient in observation group and 7 patients in control group had symptom of adductor spasm, and the efficient rates of the 2 groups were 14/15 (93%) and 8/15 (53%), respectively, and the difference has statistical significrdnce (P＜0.05); the drug used dose and anxious score and depression score of control group were higher than those of obsenration group(P＜0.05). Conclusions The nerve stimulator localization for obturator nerve block during TURBT can improve blocking success rate and quality,and it can be extensiVely used in clinic.
