A precise knowledge of depth of invasion of tumor is essential for the planning of treatment of rectal cancer. TRUS is a new diagnostic modality that has become useful in determining depth of invasion preoperatively and the presence or absence of metastatic lymph nodes. Our aim was to determine Role of Transrectal Ultrasound in Preoperative Local Staging of Carcinoma Rectum and it's Histopathological Correlation. TRUS was used in preoperative local staging of 30 patients with carcinoma rectum. 25patients underwent APR (abdomino-perineal resection) &amp; 5 underwent AR. (anterior resection). Preoperative TRUS staging was compared with pathological staging obtained from biopsy of resected specimen. In staging depth of invasion of rectal wall (T stage) overall accuracy was 83.3 %, over staged 10 %, under staged in 6.67 % sensitivity was 92.5 %, and specificity was 62.5 %. In staging lymph nodes (N stage) overall accuracy was 76.67 %, sensitivity was 79.31 %, specificity was 87.5 %. TRUS is a safe and accurate preoperative local staging method for assessment of both depth of invasion of rectal wall and presence or absence of metastatic lymph nodes.
