Item A comparative study on the use of holmium laser and pneumatic lithotripser for intracorporeal lithotripsy of upper ureteric stones(Medip Academy, 2020-01) Sharma, Elias; Langer, Raja; Dogra, Varun; Langer, BhavnaBackground: In the last decade different minimally invasive modalities for management of urolithiasis have been available requiring an intelligent decision by the urologist to choose one as per patients need and preferences.Methods: The present cross sectional study was conducted among patients who underwent ureterorenoscopic lithotripsy for proximal ureteric stones in the Department of Urology. Using consecutive sampling technique, patients were randomly allocated to two groups for treatment with either pneumatic lithotripser (group A) or Holmium laser lithotripser for fragmentation of calculi (group B) and the comparison of both these techniques was done.Results: 117 patients were included (57 and 60 in group A and group B respectively) in the study. The difference in age in the two groups was found to be statistically significant (p=0.03). The total operative time, length of stay in hospital and complications were more in group A patients. The difference in two groups for total operative time and length of stay in hospital was statistically significant (p=0.00 and 0.00 respectively).Conclusions: Holmium laser lithotripser has better safety profile when compared to pneumatic lithotripser especially in stone clearance rate and retropulsion rates and could be used as modality of choice in proximal ureteric stones.Item LGIB & the Elderly: Perspective from the Developing World.(2016) Mir, Shakeel Ahmad; Bali, Rajandeep Singh; Bansal, Baabul; Shah, Syed Mushtaq Ahmad; Dogra, Varun; Neogi, SushantoAim: To ascertain the common causes of LGIB in the elderly and to evaluate sigmoidoscopy and colonoscopy as the initial investigation for diagnosing LGIB in the elderly in the developing world. Materials and Methods: The study was conducted over a period of two years at SMHS Hospital and Government Medical College Srinagar, a tertiary care centre, Jammu & Kashmir. All the patients above the age of 60 years, presenting with symptoms or complaints of LGIB to the OPD’s and casualty services of the said hospital were enrolled in the study. Exclusion Criteria: Cases presenting with LGIB which were proved by any diagnostic procedures or during laparotomy to originate from any source proximal to ligament of Treitz. Results: The commonest cause of LGIB in our study was local anal disease [haemorrhoids and anal fissures] followed by carcinoma colorectum, inflammatory bowel disease [IBD], solitary rectal ulcers [SRUS] and colonic polyps, in the order of decreasing frequency. Colonoscopy was able to detect the cause of LGIB in all our study subjects. Conclusion: Despite the small number of patients in our study group, it can be concluded that the cause of LGIB in the elderly in our part of the world differs from that of the developed world, although the reasons for this remain unexplained and require more research. As such, elderly patients with complaints of LGIB should be offered the benefits of colonoscopy unless contraindicated by their co-morbidities because of the fact that they may be harbouring a sinister cause of LGIB, i.e., colorectal malignancy.
