9-year period 1,469, 5 institutions sperm were present in the semen in 865 of 1,012 men (86%) pregnancy occurred in 421 of 810 couples (52%) less than 3 years patency was 97% and pregnancy 76%, 3 to 8 years 88% and 53%, 9 to 14 years 79% and 44% and 15 years or more 71% and 30%. The patency and pregnancy rates were no better after 2-layer microsurgical vasovasostomy than after modified 1-layer microsurgical procedures and they were statistically the same for all patients regardless of the surgeon. When sperm were absent from the intraoperative vas fluid bilaterally and the patient underwent bilateral vasovasostomy rather than vasoepididymostomy, patency occurred in 50 of 83 patients (60%) and pregnancy in 20 of 65 couples (31%). presence or absence of a sperm granuloma at the vasectomy site affected results.

Validation of a Vasoepididymostomy Predictor Model: Is Vasoepididymostomy Truly Predictable Preoperatively? Parviz K Kavoussi MD, Erin T Bird MD

Introduction 50% divorce rate in United States 500,000 men undergo vasectomies annually 2-6% of men will desire reversal at some point Range in microsurgical training for reversals (V-V vs V-E) Sheynkin YR, Hendin BN, Schlegel PN, Goldstein M: Microsurgical repair of iatrogenic injury to the vas deferens. J Urol 1998; 159:

Model Constructed to Predict Need for V-V vs V-E Model based on: –Age –Time period since vasectomy Model validated in a 7 institution study Purpose: Allow referral to urologists trained and comfortable performing V-E’s Parekattil SJ, Kuang W, Agarwal A, Thomas AJ. Model to predict if a vasoepididymostomy will be required for vasectomy reversal. J Urol May;173(5): Parekattil SJ, Kuang W, Kolettis PN, Pasqualotto FF, Teloken P, Teloken C, Nangia AK, Daitch JA, Niederberger C, Thomas AJ Jr.Parekattil SJ, Kuang W, Kolettis PN, Pasqualotto FF, Teloken P, Teloken C, Nangia AK, Daitch JA, Niederberger C, Thomas AJ Jr. Multi- institutional validation of vasectomy reversal predictor. J Urol Jan;175(1):247-9 r

Methods IRB approval obtained 115 consecutive patients who underwent reversals included No exclusion criteria All underwent reversal by fibrin glue technique

Methods Predictor model applied to all patients Predicted outcomes analyzed with respect to outcomes with consideration to actual procedures performed Maximum follow up 30 months Median follow up 16 months

Results Out of 115 patients, 40 would have been predicted to require V-E on 1 or both sides, but actually underwent bilateral V-V Follow up data was available in 62% of these patients 88% of these were patent and 52% achieved pregnancies thus far

Predicted V-V, had V-V Number of patientsNumber successfully patent Number achieved pregnancy 70 (42 had f/u data)41 (98%)15 (36%) Predicted V-E, but had V-V Number of patientsNumber successfully patent Number achieved pregnancy 40 (25 had f/u data)22 (88%)13 (52%)

The assessed pre-operative nomogram to identify patients who might benefit from a V-E vs those who will simply need a V-V is not a reliable predictor in our patient population seeking a more affordable fibrin glue vasectomy reversal option

Conclusions Results of fibrin glue vasectomy reversal are comparable to published series Limited marketing resources are required Dealing with failures and fertility couples in general…. Future Directions
