| Abstract | Summary form only given. Benign Prostatic Hyperplasia (BPH) is one of the most common medical problem in older men. Growth in prostatic tissue obstructs the outflow of urine, slowing urination and making it impossible to completely void the bladder. The existing approved treatments for BPH are not satisfactory in many sufferers of BPH. The device in this discussion is a novel laser device using a markedly different treatment from existing surgical or medical methods. In this treatment, prostatic tissue is heated from within the prostate to the point of irreversible necrosis. There is no necessity for destruction of the urethral epithelium. Healing processes then reduce the volume of the affected tissue. This report presents results from the initial series of patients treated in a multicenter registry. The device used was a diode laser operating at a nominal 830 nm wavelength. The device uses solid state design, requires no special maintenance, and can operate from standard wall currents and voltages. The laser device is approximately 16.5 cm by 40.0 cm by 34.3 cm and weighs 11 kg. The device delivers energy to the prostate via a fiber with a 1 cm diffusing tip. Energy is delivered at programmed power settings designed to produce a large volume of coagulation in the absence of tissue char. Current treatment modes involve a carefully selected delivery of power over a 4 minute interval. |

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.
