Abstract: The evaluation of Hydronephrosis using 99mTc-DTPA renal Scintigraphy & CT- Urography has been carried out among 60 hydronephrotic patients with age groups between 20-80 year, 27 patient assessed by CT urography, 27 assessed by dynamic renal Scintigraphy and 6 patient assessed by both. The parameters discussed are the age, weight and degree of the Hydronephrosis (mild- moderate - severe). The results from dynamic renal Scintigraphy using 99mTc-DTPA radiopharmaceutical reveal that - the predominant occurrences of hydronephrosis were among the age group of 20-30 years old, While the least occurrence for the age group of 30-40 years old. The result also found that the relationship between the age and occurrence of hydronephrosis is an inverse relationship demonstrated by the following equation (y = -0.571x + 18.66). The results also reveal that the predominant occurrence of hydronephrosis were among the weight group of 50-60 kg, While the least occurrence for the weight group of 90-100 kg with inverse relation demonstrated by equation (y = -3.192x + 27). Also the result reveals the degree of hydronephrosis (mild 50 % -moderate 16.67 %- Severe 33.33 %). The results from CT urography reveal that the predominant occurrence of hydronephrosis were among the age group of 40-50 years old, While the least occurrence for the age group of 70-80 years old which has reversible relation and could be demonstrated by the following equation (y= 3.964x + 30.12). The results also reveal that the predominant occurrence were among the weight group of 50-60 kg, While the least occurrence for the weight group of 80-90 kg which has also reverse relationship demonstrated by the equation y=1.585x +22.20. Also the result reveals the degree of hydronephrosis (mild 50 % -moderate 16.67 %- Severe 33.33 %). The accuracy, resolution and cost and of these methods has been compared.
