Ultrasound, Ct-scan, and laparoscopy, diagnostic observations on non-palpable testis

ABSTRACT

To evaluate the comparative diagnostic efficacy of Ultrasound, CT-Scan, and Laparoscopy in the diagnosis of non-palpable undescended testes in pediatric patients. Comparative study. Surgical and pediatric surgical department of B V Hospital [QAMC] Bahawalpur and Allied Hospital Faisalabad. From April 2006 to April 2007. A total forty boys with non palpable testis were subjected to Ultrasound, CT-Scan and diagnostic laparoscopy in a period of one year. The patients above 12 years and with cardiovascular anomalies were excluded from the study. Laparoscopy was performed under general anesthesia and findings were compared with Ultrasound and CT-Scan. Sensitivity and specificity of each were calculated. Diagnostic accuracy of Ultrasound was 25%, CT-Scan was 64% and Laparoscopy was 100%. Sensitivity was found to be 20%, 63% and 100% and specificity was 10%. 50% and 100% for Ultrasound, CT-Scan and Laparoscopy, respectively. Diagnostic laparoscopy is far more superior as compared to Ultrasound and CT-Scan in the diagnosis of non palpable testis
