| Abstract | OBJECTIVES: To investigate the incidence of lymphocele and determine the risk factors for postoperative lymphocele after extraperitoneal robot-assisted radical prostatectomy by using propensity score-matching. METHODS: A total of 483 patients underwent extraperitoneal robot-assisted radical prostatectomy for prostate cancer between January 2009 and August 2011. Of these, 200 patients underwent pelvic lymph node dissection during robot-assisted radical prostatectomy. All patients underwent magnetic resonance imaging or computed tomography postoperatively to detect lymphocele after robot-assisted radical prostatectomy. Propensity scores for an established control group were calculated for each patient using multivariate logistic regression based on the following covariates: age, body mass index, preoperative prostate-specific antigen level, prostate volume calculated by transrectal ultrasound, biopsy Gleason sum and clinical tumor stage. RESULTS: Lymphocele was identified in 41 patients (20.5%). There were no statistical differences in variables used in propensity score-matching. Operation time, estimated blood loss, catheterization and surgical margin positivity did not show differences between the two groups. Seminal vesicle invasion (P = 0.015) and tumor volume (P = 0.042) between the two groups were significantly different. In the multivariate logistic regression model, extracapsular extension (P = 0.017, odds ratio 4.231), seminal vesicle invasion (P = 0.028, odds ratio 2.643) and the number of positive lymph nodes (P = 0.041, odds ratio 3.532) were independent risk factors for lymphocele development after extraperitoneal robot-assisted radical prostatectomy with pelvic lymph node dissection. CONCLUSIONS: Lymphocele might preferentially develop in cases with seminal vesicle invasion and large tumor volume. Additionally, extracapsular extension, seminal vesicle invasion, and the number of positive lymph nodes are independent risk factors for postoperative lymphocele after extraperitoneal robot-assisted radical prostatectomy. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
