Objective To compare the safety and clinical effect of laparoscopic partial nephrectomy ( LPN) on small renal cell carcino-ma. Methods The records of 65 patients who underwent partial nephrectomy in our hospital from March 2008 to March 2013 were retrospec-tively analyzed. 35 patients were given open partial nephrectomy and the other 30 patients were given LPN. Compared the operative time,blood loss,warm ischemia time,length of stay,positive marginrate,and occurance rate of complications between the two groups. Results There was no statistical difference in the mean size of tumor in the two groups. Compared to the OPN group,there was less blood loss,operative time, hospital stays and warm ischemia time in the LPN group. There was neither positive surgical margin nor renal function damage in the two groups. And during the follow-up period ranged from 6 to 18 months,there was no local recurrence. Conclusion Laparoscopic partial ne-phrectomy has a shorter operation time,less blood loss,shorter length of hospital stay compared with open partial nephrectomy,and it wouldn 't extend the time of warm ischemia,while the clinical effect of the two methods are similar.

Objective To analyze and summarize the clinical manifestations,diagnosis and treatment of testicular epidermoid cyst pa-tients.Methods Combined with literature,the clinical data of 7 patients with testicular epidermoid cyst in our hospital from July 2005 to Au-gust 2015 were analyzed.Results Histological examination showed testicular epidermoid cyst,postoperative recovery was good,no recurrence during 12 to 36 months’follow-up.Conclusion The testicular epidermoid cyst is rare in clinic,the clinical manifestations is similar to tes-ticular cancer,so it is often misdiagnosed as testicular cancer,which should be diagnosed by pathology,treated by testis preserved testicular tumor resection,and the prognosis is good.
