自从Clayman于1990年6月成功地为一位肾脏嗜酸细胞瘤患者施行腹腔镜肾切除术以来，腹腔镜技术在泌尿外科领域得到了较快的发展，尤其是随后5年，在肾、肾上腺、前列腺癌及输尿管结石的外科治疗方面，越来越多的泌尿外科医生开始采用这一技术，并且泌尿外科腹腔镜水平的高低成为衡量医院综合竞争力的重要标准之一。

Broodstock wintered at at 2~5℃ were fed Nitzschia closterium (30×10^4~50×10^4 cells/mL) supplemented with Chlorella sp. and egg yolk and had a mortality of 1.9%, 4.0% and 9.98% during maturation-inducing. However, the broodstock wintered at below 0℃ were fed the same food and had an increased mortality of 15.87%, 18.8%, 26.27% and 32.07% during maturation-inducing, indicating that there is influence of water temperature on survival of the broodstock during wintering period.

1当水温为2~5℃时，越冬的亲贝在促熟中是以新月菱形藻（30~50万个／mL）为主要饵料，辅以小球藻、蛋黄等，死亡率分别为1.9%，4.0%，9.98%；在0℃以下的越冬亲贝，在促熟中使用同样饵料，则死亡率提高为15.87%，18.0%，26.27%，32.07%，说明亲贝在海中越冬时，水温的高低直接影响亲贝在升温促熟饲育中的成活率。
