Trans rectal ultra sound guided prostate biopsies: a single centre experience in Sri Lanka

Trans rectal ultrasound guided prostate biopsy (TRUS) was introduced to Sri Lanka in 2002. 1. To study clinicopathological features of males subjected to TRUS biopsy 2. To compare estimation of tumour burden by two methods in carcinoma prostate (CaP). 749 symptomatic males subjected to TRUS biopsy over 64 months at a single centre. Information was retrieved from case records. Tumour burden in CaP was calculated as: 1. Calculated tumour burden (CTB)--total percentage tumour in each core/total number of cores 2. Percentage positive biopsy cores (PPBC)--number of positive cores/total number of cores X 100. SPSS 15.0, student's t test and Spearman's rank correlation coefficients were used for statistical analysis. 35.2% had CaP, microacinar in type. 34.88% were poorly differentiated. CaP was frequent among older patients (P
