 Hematoma Inadvertent biopsy of epididymis: If sperm +  epididymis level of obstruction If sperm –ve  obstruction above or primary seminiferous tubule failure
Slide 12-

Indications The absolute indications for vasography are the following (must include all three): 1. Azoospermia 2. Complete spermatogenesis with many mature spermatids on testis biopsy 3. At least one palpable vas Relative indications for vasography are the following: 1. Severe oligospermia with normal testis biopsy 2. High level of sperm-bound antibodies, which indicates unilateral, bilateral, or partial obstruction (Lee et al., 2009) 3. Low semen volume and very poor sperm motility (partial ejaculatory duct obstruction) Vasography should answer the following questions: 1. Are there sperm in the vasal fluid? 2. Is the vas obstructed? If the testis biopsy reveals many sperm, the following are indications: 1. Absence of sperm in vasal fluid indicates obstruction on the testicular side of the vasotomy site, most likely an epididymal obstruction. Vasography is done in this case with saline or indigo carmine to confirm patency of the seminal vesicle (distal) end of the vas before vasoepididymostomy. 2. Copious vasal fluid containing many sperm indicates vasal or ejaculatory duct obstruction, and formal contrast vasography is performed as described later to document the exact location of the obstruction. 3. Copious thick, white fluid without sperm in a dilated vas indicates secondary epididymal obstruction in addition to a potential vasal or ejaculatory duct obstruction.

Slide 29-

Testicular , cremasteric artery , lymphatics & vas and its vessels preserved Testis delivered 10 % recurence due to scrotal and gubernacular veins Veins ligated – cord reexamined “Impulse test”  Address hydrocoele if present
Slide 30-

In approximately 50% of cases the testicular artery is adherent to the undersurface of a large vein (Beck et al., 1992). All veins within the cord, with the exception of the vasal veins, are doubly ligated with either hemoclips (Fig. 67.50A) or by passing two 4-0 silk ligatures, one black and one white, beneath the vein (Fig. 67.50B). These are then tied and the vein divided. Medium hemoclips are used for veins 5 mm or larger, small auto-hemoclips for veins 1 to 5 mm, and 4-0 silk for veins smaller than 2 mm. The bipolar cautery can be used for veins smaller than 0.5 mm. The vasal veins are preserved, providing venous return. If the vas deferens is accompanied by a dilated vein greater than 2.5 mm in diameter, they are dissected free of the vasal artery and ligated. The vas deferens is always accompanied by two sets of vessels. As long as at least one set of deferential veins remains intact, venous return will be adequate.

Check patency by passing a prolene thread <5cm- revise If >5cm – use combination of lengthening technique >10cm- single crossed vasovasostomy Preserve sperm for IVF 2 separate anastomosis- devascularised
Slide 44-

(1) Accurate mucosa-to-mucosa anastomosis (2)Leak proof anastomosis (3) Tension-free anastomosis (4) Adequate blood supply to the ends of the vas (5) Healthy mucosa and muscularis (6) Atraumatic technique.

Lumina of varying diameters Planning  placement  3,9,11,1,5,7 Double arm inside out  10-0 mucosal – (6) 9-0 muscularis (6+4) 8-0 vasal sheath (6-8)
Slide 46-

A perfect transverse cut yielding a round ring of mucosa and a lumen directed straight down is essential oblique lumen not acceptable The convoluted vas should not be unraveled. This disturbs the blood supply at the anastomotic line The sheath of the convoluted vas may be carefully dissected free of its attachments to the epididymal tunica to prevent inadvertent perforation of adjacent convolutions Reinforce the anastomosis by approximating the vasal sheath
Slide 47-

Transposition of testis
Slide 48-

No intercourse for 3 weeks Semen analysis at 1,3,6 months 52% pregnancy If azoospermia at 6 months  Redo Hematoma Sperm granuloma Decreasing counts Encourage cryopreservation as soon as sperms appear

 Indication: Complete spermatogenesis in atleast 1 testis prior biopsy / antisperm antibody+ Absent sperm in vas No distal vasal obstruction End to end End to side Intussuseption
Slide 51-

 Adv : Fluid examined Easy identification of level of obstruction Allows upward mobilisation of vas to bridge large gap Disadv : Hemostatis Tubule identification and closure Vasal blood supply from inferior epididymal A lost
Slide 52-

 Adv : Bloodless Fluid examined before anastomosis Disadv : Difficult suturing in collapsed tubule
Slide 53-

The vas deferens is drawn thru an opening in the tunica vaginalis and secured in proximity to the anastomotic site with two to four interrupted sutures of 6-0 polypropylene placed through the vasal adventitia and the tunica vaginalis. The vasal lumen should reach the opening in the epididymal tunica easily, with length to spare. The posterior edge of the epididymal tunica is then approximated to the posterior edge of the vas muscularis and adventitia with two to three interrupted sutures of double-armed 9-0 nylon (Fig. 67.30). This is done in such a way as to bring the vasal lumen in close approximation to the epididymal tubule selected for anastomosis
Slide 54-

 Adv: Four points of fixation Bloodless anastomosis Disadv : Cannot assess tubular fluid before setup

Open tubule technique During intraop reconstructive, isolated Median raphe Tunica opened Epididymis 16-25X Incised over a dilated tubule Tubule isolated – 150 knife
Slide 70-

Open Tubule Technique The technique described here can be employed for either intraoperative sperm retrieval at the time of vasoepididymostomy or as an isolated procedure in men with congenital absence of the vas or unreconstructable obstructions (Matthews and Goldstein, 1996; Nudell et al., 1998). A median raphe approach through two small transverse scrotal incisions within the scrotal skinfolds are made. After delivery of the testis, the tunica vaginalis is opened and the epididymis inspected under 16× to 25× magnification using the operating microscope. The epididymal tunica is incised over a dilated tubule as described previously for vasoepididymostomy. Meticulous hemostasis is obtained using the bipolar cautery. A dilated tubule is isolated and incised with a 15-degree microknife. The fluid is touched to a slide, a drop of human tubal fluid media is added, a cover slip is placed, and the fluid is examined. If no sperm are obtained, the epididymal tubule and tunica are closed with 10-0 and 9-0 monofilament nylon sutures, respectively, and an incision is made more proximally in the epididymis or even at the level of the efferent ductules until motile sperm are obtained.
Slide 71-

As soon as motile sperm are found, a dry micropipette (5 μL; Drummond Scientific Co., Broomall, PA) is placed adjacent to the effluxing epididymal tubule (Fig. 67.34). A standard hematocrit pipette is less satisfactory but can be used if micropipettes are not available. Sperm are drawn into the micropipette by simple capillary action. Negative pressure, as is generated by action of an in-line syringe, should not be applied during sperm recovery because this may disrupt the delicate epididymal mucosa. Two micropipettes may be employed simultaneously to increase speed of sperm recovery. The highest rate of flow is observed immediately after incision of the tubule. Progressively better quality sperm are often found after the initial washout. Gentle compression of the testis and epididymis enhances flow from the incised tubule. With patience, 10 to 20 μL of epididymal fluid can be recovered.
Slide 72-

The micropipette is connected to a short (3–5 cm) segment of medical grade silicone tubing (American Scientific Products, McGaw Park, IL). Alternatively, the tubing attached to a 25-gauge butterfly needle may be employed. A 20-gauge needle fitted to a Luer-tip syringe is then placed in line. The fluid is flushed with IVF media (0.5–1.0 mL) into a sterile container. Once a micropipette has been used, it is discarded. Residual fluid in the pipette will disrupt capillary action. A typical procedure requires 4 to 12 micropipettes. The sperm bank should be instructed to cryopreserve the aspirate in multiple vials (aliquots) so that several IVF cycles may be attempted if required

injected with 1 mL of Ringer’s lactate solution with a 1-mL tuberculin syringe to confirm its patency If further proof of patency of the vas deferens is desired, 1 mL of 50% dilute indigo carmine may be injected and the bladder catheterized. The presence of blue/green dye in the urine confirms patency of the vas.
