It is estimated that 3-6% of all vasectomised men request vasectomy reversal for different reasons. Microsurgical vasovasostomy is the gold standard technique of vasectomy reversal. However, the microsurgical technique is time-consuming and challenging to most urological surgeons. Therefore, alternative methods of vasal anastomosis have been studied including robotic-assisted vasovasostomy. Thi...

Objective Background: 2% to 6% of vasectomized men will ultimately seek vasectomy reversal and late stricture and obstruction after operation are relatively common. Objective: To find a method for improving of vasovasostomy outcomes, we used intra-operative local mitomycin-C to prevent possible fibrosis and stricture. MaterialsAndMethods Design, setting, and participants: 44 patients in our ref...

two hundred and forty patients, who had undergone vasectomy from 1977 to 1985 and subsequent vasovasostomy ,were studied for the presence of sperm-specific antibodies by using the kibrick's gelatin agglutination test. the number of successful pregnancies and the presence of agglutination were also considered in this survey. sixty-nine pregnancies occurred in total and agglutination was present ...

Between 1975 and 2003, a total of 4010 patients have undergone microscopic vasectomy reversal by 1 surgeon at 1 institution. Of these cases, 3904 had available records and 1735 were successfully contacted to obtain reliable long-term data. A total of 1556 (89.7%) were able to establish a pregnancy in their female partner, resulting in 2111 pregnancies. When there was no sperm in the vas fluid a...

Up to 6% of men who have undergone vasectomy will ultimately elect for reversal in the form of vasovasostomy or vasoepididymostomy for various reasons. Vasovasostomy performed to regain fertility is a technique that has undergone numerous advances during the last century, including the use of microsurgical equipment and principles to construct a meticulous anastomosis. It is important during va...

PURPOSE We determined whether men who may have partial obstruction and antisperm antibodies after vasovasostomy can be distinguished from other infertile men with antisperm antibodies only, and whether repeat microsurgical reversal is beneficial in such patients. MATERIALS AND METHODS A total of 412 patients underwent indirect immunobead testing for antisperm antibodies at our laboratory from...

BACKGROUND A retrospective review was made of patients who received vasectomy reversal from 1989 to 1998 at Chang Gung Memorial Hospital (CGMH) in Linkou, Taiwan. The patency rate and partner pregnancy rates were also analyzed. METHODS Seventy patients underwent a vasovasostomy at CGMH from 1989 to 1998. Postoperative semen analysis and achievement of pregnancy in a partner were examined. Var...

INTRODUCTION In line with the effort to evaluate feasible surgical options for vasectomy reversal and to increase patients' willingness to undergo the procedure, this study reported on a technique for ambulatory mini-incision microsurgical vasovasostomy using a double-ringed clamp (i.e. Moon's clamp). This technique does not require the use of dilators, approximators and other accessory devices...

OBJECTIVE To evaluate the application of a microsurgical two-layer anastomosis technique in the treatment of failed vasectomy reversal. METHODS A microsurgical two-layer anastomosis was used in a series of 24 patients with confirmed anastomotic obstruction after previous vasectomy reversal. The patients were followed up for 9 months to 6 years, and the efficacy of the procedure was evaluated ...
