There are several options for the treatment of varicocele, including surgical repair either by open or microsurgical approach, laparoscopy, or through percutaneous embolization of the internal spermatic vein. The ultimate goal of varicocele treatment relies on the occlusion of the dilated veins that drain the testis. Percutaneous embolization offers a rapid recovery and can be successfully accomplished in approximately 90% of attempts. However, the technique demands interventional radiologic expertise and has potential serious complications, including vascular perforation, coil migration, and thrombosis of pampiniform plexus. This review discusses the common indications, relative contraindications, technical details, and risks associated with percutaneous embolization of varicocele.

Prior studies have investigated sperm retrieval rates in men with non obstructive azoospermia(NOA)secondary to specific etiologies,yet most cases of NOA are *** compared sperm retrieval rates and testicular histopathology in idiopathic NOA(iNOA)and nonidiopathic NOA(niNOA).We performed a retrospective review of men with NOA who underwent microdissection testicular sperm extraction(microTESE)between 2000 and *** with no history of malignancy or cryptorchidism and negative genetic evaluation were considered *** regression determined the association between idiopathic etiology and primary outcomes of sperm retrieval and active spermatogenesis on *** 224 men,86(38.4%)were idiopathic,75(33.5%)were nonidiopathic,and 63(28.1%)did not undergo genetic *** age and serum testosterone were higher among iNOA or no testing versus *** follicle-stimulating hormone(FSH)was lower among iNOA or no testing versus niNOA.A higher proportion of iNOA or no testing versus niNOA had a clinical *** retrieval rates were similar between iNOA,niNOA,and no testing(41.8%vs 48.0%vs 55.6%,respectively;P=0.255).Active spermatogenesis was seen in a higher proportion of iNOA or no testing versus niNOA(31.4%and 27.0%vs 16.0%,P=0.073).On multivariable analysis,iNOA was not associated with sperm retrieval or spermatogenesis(P=0.430 and P=0.078,respectively).Rates of sperm retrieval and spermatogenesis on testis pathology were similar in men with iNOA and *** data will be useful to clinicians in preoperative counseling for men with NOA and negative genetic evaluation.

作者： joshua A.halpern Arighno Das Robert E.Brannigan Department of Urology Northwestern University Feinberg School of MedicineChicagoILUSA

Dear Editor,Eagle-Barrett or prune belly syndrome(PBS)is a rare congenital condition with an estimated incidence of 3.8 cases per 100000 live births in the United States[1].The syndrome is characterized by cryptorchidism,upper and lower urinary tract dilation,and either absence or deficiency of the abdominal wall *** much of the literature has focused upon urinary tract malformation and cryptorchidism,fertility is a crucial aspect of urologic evaluation and care in these patients.
