Fine needle aspiration vs. mTESE in non-obstructive azoospermia.
This study was carried out on 100 patients with non-obstructive azoospermia (NOA) to compare between results and complications of fine needle aspiration (FNA) vs. microdissection testicular sperm extraction (mTESE) sperm retrieval. They underwent history taking, clinical examination, semen analysis, serum follicle stimulating hormone estimation and scrotal Duplex. One testis was subjected to FNA screening whereas the other testis was subjected to mTESE and histopathology. Follow-up was by ultrasonography at 1, 3 and 6 months. The overall sperm retrieval rate was 54% by mTESE and 10% by FNA. Spermatozoa were retrieved by mTESE from all cases with hypospermatogenesis, severe hypospermatogenesis, 30% of Sertoli cell only (SCO), 16.7% of germ cell arrest and in 28.6% of tubular hyalinization. Sperms were retrieved by FNA in 33.3% of hypospermatogenesis, 9% in severe hypospermatogenesis, 5% in SCO, 16.7% in germ cell arrest, while no sperms were retrieved in the tubular hyalinization group. The total complication rate following mTESE was 10% in the early phase and none in the long-term follow-up compared to 24% of FNA side. It is concluded that mTESE is superior to FNA as regards sperm retrieval rate and lower incidence of complications in NOA patients.
