Ultrasound is a favourite first line imaging technology for the evaluation of kidneyfunction. Pakistan, which use tobacco products more than 72 percent of the adult male population. Cigarette smoking has emerged over the past few years as an important independent renal risk factor, apart from its conventionally recognized carcinogenic effects and its adverse function as a driver of cardiovascular illness. Smoking is closely linked to significant clinical findings due to changes seen in renal function. The possible association between sensitivity to tabaco smoke and renal ultrasound measurements is yet to be examined. We hypothesized that tobacco consumption is correlated with decreased renal measurements. Objective: The possible association between sensitivity to tabaco smoke and renal ultrasound measurements is yet to be examined. We hypothesized that tobacco consumption is correlated with decreased renal measurements. Approach: This was an observational cross-sectional study in which we observed 385 male patients on Ultrasound within Age range of 20Years to 80Years. We assessed all patients by self-questionnaire. Data was collected from private sector hospital Gujrat, Pakistan. Results: There were 385 people in total who were evaluated. A statistically important relation was established between kidney measurements and the following independent variables. There was no statistically important correlation between kidney, high blood pressure or diabetes. All smoking participants have equal echogenicity. Conclusions: Individuals with a longer smoking history had smaller kidneys. This is especially important considering that statistically significant associations between renal dimension and smoking. As we observe 385 males on ultrasound and assessed by self-questionnaire. In which 40.3% have hypertension and 10.1% are diabetic. 270 patients from 385 have decreased dimensions. Our results show the length, width and parenchymal thickness are decreased .70.1 % smokers have
