Abstract
Background: Urolithiasis is a common disease universally and is known to affect patients all over the globe irrespective of race, culture or geographic boundaries. Recent studies have also demonstrated a changing composition of urolithiasis as well as an appreciable increase in the incidence of stone disease in females and younger patients over the last decade.
Objectives: To assess the association between value of Hounsfield unit (HU) measurement of urinary calculi as measured on NCCT (KUB) and the skin to stone distance (SSD) as measured on NCCT on the stone free status after ESWL at 4 weeks follow up.
Methodology: All patients referred to department of Radiology, Shadan Institute of Medical Sciences, Hyderabad will be screened and those patients meeting the study inclusion criteria will be informed for the study. For the purpose of the study an informed consent, will be obtained. The study proforma will be completed for every patient included in my study
Results and Discussion: The mean age of the patients in the study was 44.0±13.1 years. The age of the patients ranged from 19-75 years. Maximum nuber of patients (30 patients 50%) belongs to the age group of 21-40years. out of the 12 patients 4 (33.3%) had successful outcome and 8 (66.7%) had unsuccessful outcome. Among the 30 patients belonging to the group 500-1000 mean HU, 20 (66.6%) had successful outcome and 10 (33.3%) had unscuccessful outcome. Out of 18 patients who had > 1000 mean HU, 10 (55.5%) had successful outcome and 8 (44.5%) had unsuccessful outcome.
Conclusion: lower pole stone was observed in 30.7% of the lithotripsy success group of patients and 69.3% in lithotripsy unsuccessful group. Statistically there was a significant difference between the lithotripsy success and unsuccessful group. Lower pole stones had significantly higher failure rate.
