Need for sperm retrieval and cryopreservation at vasectomy reversal.

PURPOSE: Controversy exists on whether to obtain sperm for cryopreservation routinely at vasectomy reversal. With recent improvements in in vitro fertilization with intracytoplasmic sperm injection, it is now possible to obtain a small amount of testicular tissue for cryopreservation in the event of reversal failure. However, to our knowledge no studies exist of who is most likely to benefit from this procedure. MATERIALS AND METHODS: We reviewed 84 consecutive vasectomy reversals performed by 1 surgeon (J. I. S.) between July 1996 and March 2000 with followup available for 77. We grouped cases by procedure as vasovasostomy, vasoepididymostomy and vasovasostomy with vasoepididymostomy as well as bilateral or unilateral. Sperm was retrieved at reversal in 15 of 46 vasovasostomy (none used), 11 of 18 vasoepididymostomy (3 used) and 13 of 20 vasovasostomy with vasoepididymostomy (none used) cases. RESULTS: The overall anastomotic patency rate after unilateral or bilateral vasovasostomy, unilateral vasovasostomy with contralateral vasoepididymostomy and unilateral or bilateral vasoepididymostomy was 96%, 83% and 57%, respectively. The natural pregnancy rate without in vitro fertilization was 57%, 50% and 14%, respectively. The most recent vasoepididymal anastomoses were performed by the Berger triangulation technique with a 78% patency and 25% pregnancy rate. Only 8% of men with banked sperm eventually used it for assisted reproductive techniques, in whom unilateral or bilateral vasoepididymostomy failed in all. CONCLUSIONS: We currently do not recommend routine sperm retrieval for cryopreservation in men who undergoing vasovasostomy. We encourage men who require bilateral vasoepididymostomy to bank sperm at reversal. In men who undergo vasovasostomy with vasoepididymostomy we base the decision on preoperative counseling and intraoperative findings.

Resolution of urge symptoms following sling cystourethropexy.

PURPOSE: Persistence of urinary urge symptoms in women after pubovaginal sling cystourethropexy is a distressing problem. We assess the ability of preoperative video urodynamics to identify patients in whom urinary urge symptoms failed to resolve postoperatively. MATERIALS AND METHODS: The records of 84 consecutive women who had undergone pubovaginal sling cystourethropexy were reviewed. Preoperative video urodynamics revealed stress urinary incontinence in all cases and concomitant detrusor instability in some. Cases of motor urge, defined as urge symptoms plus detrusor instability, were divided into low and high pressure categories. Patients with urge symptoms but no demonstrable detrusor instability on video urodynamics were diagnosed with sensory urge. Postoperatively complete urge resolution was defined as total absence of symptoms without pharmacological therapy. Mean followup was 26.7 months (range 2 to 62). RESULTS: Of the 84 patients 41 with motor urge and 28 with sensory urge had preoperative urge symptoms. Complete resolution or improvement in urge symptoms occurred in 24 (58.5%) and 7 (17.1%) of the motor urge, and 11 (39.3%) and 9 (32.1%) of sensory urge cases, respectively. Of the 41 patients with motor urge 23 had low pressure instability, which completely resolved in 21 (91.3%) and improved in 2 (8.7%). Of the 18 remaining patients with high pressure motor urge only 5 (27. 8%) had complete resolution of urge and 5 (27.8%) had improvement. CONCLUSIONS: Our results suggest that patients with low pressure motor urge are significantly more likely to experience resolution of urinary urge symptoms after pubovaginal sling cystourethropexy than those with high pressure motor urge or sensory urge.

Testicular amyloid deposition as a cause of secondary azoospermia.

We present a case of secondary infertility due to familial amyloidosis. The patient presented with azoospermia, and no other sequela of the disease. A testis biopsy revealed tubules demonstrating full spermatogenesis interspersed with hyalinized tubules containing amyloid, confirmed with Congo red stain. A discussion regarding testicular amyloidosis is presented as well.

The use of methotrexate in polymyalgia rheumatica.

OBJECTIVE: To examine the efficacy and steroid sparing potential of methotrexate (MTX) in the treatment of polymyalgia rheumatica (PMR) without giant cell arteritis. METHODS: 43 patients with PMR were treated with MTX 7.5 mg/wk for 3 months. This dose was raised to 10 and finally 12.5 mg/wk MTX if the desired response was not obtained. RESULTS: No patient benefitted clinically or statistically from treatment with MTX. CONCLUSION: MTX is of no benefit in the treatment of PMR.

The impact of pre-donated autologous blood and intra-operative isovolaemic haemodilution on the outcome of transfusion in patients undergoing radical retropubic prostatectomy.

OBJECTIVE: To assess the impact of pre-donated autologous blood and intra-operative isovolaemic haemodilution on the outcome of transfusions in patients undergoing radical retropubic prostatectomy. PATIENTS AND METHODS: The charts and transfusion records of 192 consecutive patients undergoing radical retropubic prostatectomy were reviewed retrospectively. RESULTS: Of 192 patients, 14% required homologous transfusions, the rate of which varied significantly depending upon blood availability (autologous, haemodilution or homologous) (P < 0.001): 66% of patients with only autologous blood available were transfused a mean of 1.96 units (range 1-6) of blood, of which 87% received autologous alone. 12% both autologous and homologous and 1% homologous blood only. Of the pre-donated autologous units, 44% were wasted. CONCLUSIONS: Both the pre-donation of autologous blood and intra-operative isovolaemic haemodilution lower the risk of homologous blood transfusion. It is recommended that patients pre-donate 2 units of autologous blood and undergo intra-operative isovolaemic haemodilution before radical prostatectomy.
