A RETROSPECTIVE STUDY OF ESWL IN URINARY LITHIASIS WITH AND WITHOUT STENTING
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 94
Abstract
BACKGROUND Urolithiasis is the most common urological disease with a prevalence rate of 10% - 15%. Most patients harbouring “simple” renal calculi (less than 2 cm) can be treated satisfactorily with ESWL (Extracorporeal shock wave lithotripsy). The insertion of Double J (DJ) stents during ESWL of renal calculi is controversial. This study aims to understand the necessity and also “pros and cons” of DJ stenting during ESWL procedures. MATERIALS AND METHODS The retrospective observational study was conducted at the Department of Urosurgery, RG Kar Medical College and Hospital, Kolkata. 162 patients had undergone ESWL for renal stone in the Department of Urosurgery during the study period, that is Feb 2013 to Dec 2014. Detailed documentation of clinical profile of patients as well as their radiological reports from records were put in two groups. Group A consisted of patients who underwent no stenting or those who underwent prior stenting one week before which was removed at procedure. Group B consisted of patients who underwent stenting during the procedure with removal after 6 weeks. Records as present regarding infection, blockage, encrustation and migration were documented till six weeks follow-up visit. Stone clearance and complication rates were calculated in the groups. RESULTS Though stone clearance rates were similar in stented and non-stented groups, urinary tract infection was significantly more in the group where stent was retained for six weeks after ESWL. CONCLUSION Therefore, in the debate of ESWL with or without stent urinary tract infection appears to be a major disadvantage, thus limiting stent use to specific situations.
