Objectives To compare the outcomes of 2 techniques of varicocelectomy in patients with varicocele.Methods The study included 80 patients with varicocele,and patients were randomly divided into two groups,low-approach microscopic group (L-MV group,40 cases) and laperoscopic varicocectomy group (LV group,40 cases).two groups of patients are compared with preoperative and postoperative 1,3 and 6 months of semen quality changes with operation time;Operation cost;Intraoperative blood loss and postoperative complications (hydrocele and recurrent varicocele) and pregnant rate and so on,all patients were followed for an average of 11 months(range 6 to 18 months).Results L-MV and LV group postoperative sperm density,sperm counts and sperm motility than preoperative have improved significantly(P ＜0.05),but the postoperative 1,3,6 months of semen quality parameters is no statistical difference(P ＞ 0.05),L-MV group operating time whether unilateral or bilateral group were longer than the LV unilateral or bilateral needed operation time (P ＜ 0.05);L-MV operation costs less than LV group(P ＜ 0.05);Intraoperative blood loss between the two groups have no significant difference (P ＞ 0.05);Postoperative complications,follow-up for half a year,incidence of hydrocele L-MV set to 0,15％ incidence of LV gnup,differences between the two groups was statistically significant(P ＜0.05);Postoperative recurrence of VC,L-MV set to 0,10％ incidence of LV group,between the difference was statistically significant (P ＜ 0.05);Postoperative the pregnancy rate at 1 year L-MV group was 34.28％,the LV group was 21.9％,Postoperative pain symptoms were improved in both groups,and occasional scrotal mild postoperative pain were recorded in about 10 days.Conclusions The above two kinds of operation in the treatment of varicocele,low-approach microscopic is better efficacy than laparoscopic varicocelectomy,which is a kind of more economic,effective treatment,where the equipment and ability,should give the promotion,as the preferred treatment.

肾癌有遗传和散发两种形式。近年来,国内外对遗传性肾癌的病因及临床诊治的报道较多。目前已经明确的4类遗传性肾癌包括希佩尔-林道病、遗传性乳头状肾癌、BIRT HOGG DUBE综合征、遗传性平滑肌瘤病肾癌。本文就其研究进展进行综述,借此提高对遗传性肾癌的认识。
