Objective: To report our prelimilary experience of laparoscopic radical prostatectomy (LRP) for clinically localized prostatic ***:23 cases with localized prostatic cancer underwent LRP in our institution from October 2000 to August 2003. The median age was 64.5 years old, the median PSA was 13 ng/ml and median Gleason score of biopsy specimens was < 7. The operations were performed according to Montsouris technique. Briefly, operations were carried out transperitonealty, combining posterior and anterior approachs to the prostate, transecting the bladder neck, lateral dissection of the prostate, urcthrovesical anastomosis, completing the ***:No death and no conversion rate were observed in this series of 23 cases of LRP. No re-intervention was needed. The median operating time was 325 minutes (range 270 to 660 min) including the lymphadenectomy phase that was considered necessary in the case whose PSA value was 51ng/ml and pathological reading was negative to thoses lymph nodes; The median intraoperative blood loss was 430 ml(rang 200 to 1100 ml). Postoperative bladder catheterization time was 20 days. Surgical positive margin was found in I case of pathlogical stage of pT 2b and Casodex 50 mg had been used on this case for 3 mon after the PSA value was < 0.2 ng/ml. Postoperation follow-up of 3 to 24 mo. showed no signs of complications such as urethral stricture or urine incontinence. The PSA concentrations was < 0.3 ng/ml in all ***: LRP provides a clear and magnified anatomical image to allow a more precise and safer dissection.

Unsupervised domain adaptation(UDA) studies how to transfer a learner from a labeled source domain to an unlabeled target domain with different distributions. Existing methods mainly focus on matching marginal distributions of the source and target domains, which probably leads to a misalignment of samples from the same class but different domains. In this paper, we tackle this misalignment issue by achieving the class-conditioned transferring from a new perspective. Specifically, we propose a method named maximizing conditional independence(MCI) for UDA, which maximizes the conditional independence of feature and domain given class in the reproducing kernel Hilbert spaces. The optimization of conditional independence can be viewed as a surrogate for minimizing class-wise mutual information between feature and domain. An interpretable empirical estimation of the conditional dependence measure is deduced and connected with the unconditional case. Besides, we provide an upper bound on the target error by taking the class-conditional distribution into account, which provides a new theoretical insight for class-conditioned transferring. Extensive experiments on six benchmark datasets and various ablation studies validate the effectiveness of the proposed model in dealing with UDA.
