PURPOSE: To evaluate the value of epididymal distension in predicting the success of percutaneous epididymal sperm aspiration (PESA) procedure.
METHODS: Physical examination of epididymis to detect epididymal distension and PESA were performed in 49 obstructive azoospermic patients divided into two groups according to its causes (Group I: previous vasectomy, n = 27 and Group II: other causes, n = 22).
RESULTS: Epididymal distension was found in 42 cases (85.7%). PESA was successful in 42 out of the 49 patients, giving a sperm retrieval rate of 85.7%. The success rate of PESA in Groups I and II is 92.6 and 77.3%, respectively. The accuracy, sensitivity, specificity, and positive and negative predictive value of epididymal distension for the overall patients were 86.7, 90.5, 64.2, 93.8, and 52.9%, respectively. The success rate of PESA procedure in patients with epididymal distension was significantly higher than in patients without epididymal distension (p < 0.05).
CONCLUSIONS: The presence of epididymal distension in obstructive azoospermic men was predictive of PESA success.
