Background: To report a rare case of a left ejaculatory duct that allotropically protrudes or invades towards the left vesicle triangular area with its dead end. Materials and Methods: The patient simultaneously exhibited multiple congenital malformations of the homolateral urogenital system, such as the absence of a left kidney, the dysplasia and allotopia of the left seminal vesicle, the abse...

OBJECTIVES To describe the retrieval spermatozoa technique for cryopreservation after death, including the proximal part of vas deferens. MATERIAL AND METHODS A 28-years old man, with previous history of infertility, who died 12 hours ago, was submitted to spermatozoa retrieval for cryopreservation, with surgical bilateral resection in bloc of the proximal part of vas deferens, testicle and e...

BACKGROUND Insufficient vas length for performing a tension-free vasovasostomy is a problem occasionally encountered by microsurgeons. Herein we evaluated utilization of a non-vascularized vas deferens autograft in a rat model. METHODS Segments of isolated vas deferens, 2.5 cm in length, were used as bilateral autografts in 15 rats. Each autograft was implanted between the two transected ends...

Abstract word count: 199) 25 26 Background: Insufficient vas length for performing a tension-free vasovasostomy is a 27 problem occasionally encountered by microsurgeons. Herein we evaluated utilization of a 28 non-vascularized vas deferens autograft in a rat model. 29 Methods: Segments of isolated vas deferens, 2.5 cm in length, were used as bilateral 30 autografts in 15 rats. Each autograft w...

There is good evidence that in vascular smooth muscle, the relaxant effects of sodium nitroprusside (SNP) are mediated by increases in cGMP levels and activation of cGMP-dependent protein kinase (PKG). However, in rat vas deferens and rat distal colon, cGMP-elevating agents such as SNP and atrial natriuretic factor (ANF) have been shown to elevate cGMP without inducing relaxation. The lack of r...

Our laboratory has previously shown that the vacuolar H(+)-ATPase, located in a subpopulation of specialized cells establishes a luminal acidic environment in the epididymis and proximal part of the vas deferens (Breton S, Smith PJS, Lui B, and Brown D. Nat Med 2: 470-472, 1996). Low luminal pH is critical for sperm maturation and maintenance of sperm in a quiescent state during storage in thes...

Fractures of the proximal humerus are common. Most can be treated conservatively with good results. However, there is no uniform treatment of displaced fractures. One option was the PlantTan Plate (PTP). We present a study of 65 patients with displaced proximal humeral fractures treated with the PTP. Patients were followed-up for 24 months assessing fracture healing, functional outcome, pain an...

vas was too long to anastomose with the proximal end of the vas, or if the distal vas end retreated into the pelvis and was inaccessible at the inguinal area. This procedure is the same as previously reported. 3 If no sperm were found in the fluid from the proximal vas end, a secondary epididymal obstruction was considered, and the modified transverse intussusception vasoepididymostomy (VE), wh...

The objective of this study was to investigate the effect of brimless compared with ischial ramus containment (IRC) prosthetic sockets when using vacuum-assisted suspension (VAS) on persons with a unilateral transfemoral amputation (TFA). A randomized crossover design with a 2 d accommodation was used. People with unilateral TFA (n = 9 analyzed) were enrolled. Interventions were IRC VAS and bri...
