Recent advances in microsurgical treatment of varicocele and microTESE

The article deals with the recent developments in microsurgical techniques for microscopic varicocele surgery and microdissection testicular sperm extraction (microTESE). In varicocele surgery, recent developments have led to intraoperative microvascular Doppler diagnosis, three-dimensional magnification, and clipless ligation of the spermatic veins with preservation of the spermatic arteries. In microTESE, the benefits include preoperative triplex microvascular Doppler diagnosis, hydrodissection of testicular tubules and high magnification of the tubules in vivo with possible micrometry of the tubules, selection of tubule collection sites with a greater likelihood of sperm presence, and a high degree of protection of surrounding testicular tissue. The procedures are demonstrated in the photo documentation.
