Doppler Resistive Index as a Predictors of Sperm Retrieval in Azoospermic Iraqi Patients


Objective: To evaluate the Doppler ultrasound in prediction the success of sperm retrieval in Iraqi azoospermic patient using the resistive inde x(RI).Methodology: This cross sectional study conducted in the Doppler unite and the Fertility centre in the AL-Sadder Medical City in a period between April 2013 and January 2014 .The study included 72 patients with azoospermia, their age ranging from 20 to 50 years , US and Doppler study were done for them prior to testicular sperm extraction (TESE) . Statistical analysis was done by using SPSS version 20 in which use two by two tables to compute different accuracy measures.Results: There were 33 patients with positive post surgical results and 39 patients with negative results. The accuracy of RI in predicting post surgical result was (76.4%). The study shows that when the size of the testis was normal and the RI was < 0.7, the accuracy of the successful rate of sperm retrieval will be higher (82.2%) and when the size of the testis was small and the RI ≥ 0.7, the accuracy was lower (66.7%).Conclusion: This study concludes that Doppler ultrasound using RI parameter can be use as a predictor of sperm retrieval in azoospermic patients and this will be increase if taken with testicular size parameter. Recommendations: This study recommends the use of RI parameter of Doppler ultrasound and testicular size as a predictor of sperm retrieval in azoospermic patients .
