Abstract: This hospital based study was under-taken to determine the commonest ultrasonographic (US) features of obstructive uropathy (OU) in Sudanese patients and to correlate these features with the clinical symptoms and the other radiological and laboratory investigations. A total of hunderd cases were selected from in-patiants in the Urology Department of Ibn Sina Hospital during the period January 1998 to June 1998. The majority of cases were from the Capital Khartoum (92 percent) with the male to female ratio (82 percent : 19 percent), approximately (4:1), the majority were above the age of twenty years (80 percent). The most frequent changes in the (UT) detected by (US) were hydronephrosis (HN) (70 percent), followed by thickening of the urinary bladder wall( 47 percent) and hydro-ureter (HU) (40 percent). The most frequent lesion causing (OU) was urolithiasis (40 percent), of which (25 percent) were renal stones, (14 percent) were ureteric stones, (9 percent) in the right and (4 percent) in the left and (1 percent) vesical stone. Both kidneys were equally affected (12 percent) each. Carcinoma of the urinary bladder was the second commonest obstructive lesion (18 percent), with male to female ratio (11 percent : 7 percent), approximately (2 : 1), followed by urethral stricture, the third commonest causative lesion (17 percent), all were males with a higher incidence in the adults (52.9 percent). Benign Prostatic Hyperplasia (BPH) was the fourth (15 percent and all were above the age of fifty five. Lesions and obstructive changes were detected by (US) in (88 percent) of cases, (12 percent) showed no (US) abnormalities in the (UT), most of those (11 percent) were cases of urethral stricture. The percentage of incidence of the other uncommon obstructive lesions were, Bladder Neck Obstruction (BNO) (4 percent), post-prostatectomy stricture (4 percent), carcinoma of the prostate (2 percent) pelvi-ureteric junction obstruction (PUJO) (2 percent) and ureterocoele (2 percent). The incidence of the other rare causes in this study were, Posterior Urethral Valve (PUV) (1 percent), carcinoma of the cervix (1 percent), Renal Cell Carcinoma (RCC) (1 percent) and ureteral meatal stenosis, (pin-hole meatus) (1 percent) .
