The three major scrotal anomalies are bifid scrotum, penoscrotal transposition, and ectopic or accessory scrotum. Bifid scrotum occurs if the genital swellings fail to fuse at the scrotal septum. Penoscrotal transposition results from abnormal genital tubercle development. This is associated with delay in the midline fusion of the urethral folds. Ectopic and accessory scrotum result from cleavage or abnormal migration of the genital swellings. Ectopic scrotum is extremely rare. His right scrotum was normal in position and size, and contained a normal palpable testis. The penis was showed externally normal appearance. At operation it was possible to excise the scrotal wall, preserving the vas deferens and the testicular vessels. Accessory scrotum has not been recorded in Korea. We experienced a case of unilateral ectopic scrotum and a case of accessory scrotum.

Congenital anomaly of the vas deferens is often easily diagnosed by careful examination of the scrotum as well as by present popularity of vasectomy. By the fact that both systems originate from a common urogenital ridge of mesoderm, anomaly of the kidney has long been recognized to coexist with anomaly of the vas deferens. So, inability to palpate the vas deferens in routine examination or absence of vas deferens in vasectomy should alert the physician to study the patient for associated renal anomaly. We report one case of vas anomaly associated with ipsilateral renal hypoplasia with the brief review of literatures.

Duplication of the vas deferens is a very rare congenital anomaly in which two vasa deferentia coexist within the spermatic cord. Duplication of the vas deferens can be found during herniorrhaphy, vasectomy, and varicocelectomy performed on the spermatic cord or around the spermatic cord. However, it is estimated that the incidence of duplication of the vas deferens is under-reported and under-recognized. Unless anomalies of the vas deferens such as duplication of the vas deferens are recognized by surgeons, it will be difficult to reduce vas deferens injuries and achieve a satisfactory surgical outcome. In addition, care should be taken in cases of duplication of the vas deferens because it can be complicated by non-testicular genitourinary anomalies. We report a case of duplication of the vas deferens discovered during routine varicocelectomy.

Traumatic dislocation of the testis occurs when a normally distended testis assumes, as a result of trauma, a non-scrotal position by passing along fascial plane and through normal anatomic aperture. Less than 50 cases of true traumatic dislocation have been reported. The etiology, classification and treatment of testicular luxation are reviewed briefly. If efforts at closed reduction are unsuccessful, management requires surgical exploration and orchiopexy. The prognosis for recovered or fertility potential after this repair of dislocation of the testis is good. We report the case that one testis has traumatic dislocation with a ruptured vas deferens and the other has a primary spermatogenic defect.

OBJECTIVEStudying on the routes of vas deferens to provide anatomy basis for surgical operation, especially, reconstruction of long segment loss of vas deferens.

METHODSThe routes of vas deferens were observed and anatomic distances along epididymal, infrainguinal, inguinal, retroperitoneal and ampullar segments of vas deferens, the distances from external ring to extremity of vas deferens were measured respectively in 18 formalin fixed adult cadavers.

RESULTSThe vas deferens have a large curve from external ring to extremity in its route, draw it out from the external ring. Eliminating this curve will allow to shorten this segment of vas deferens for vasovasostomy by 6.1 - 12.9 (9.31 +/- 1.30) cm. The length of each segment of vas deferens, respectively, is epididymal: 3.2 - 5.6 (4.53 +/- 0.79) cm, infrainguinal: 4.5 - 9.5 (7.31 +/- 1.78) cm, inguinal: 4.4 - 7.5 (5.52 +/- 0.74) cm, retroperitoneal: 12.5 - 19.5 (16.75 +/- 1.87) cm and ampullar: 2.9 - 3.8 (3.63 +/- 0.23) cm. There was no significant differences in segment length and the distances from external ring to extremity of vas deferens between the right and left.

CONCLUSIONReconstruction of long segment loss of vas deferens can be performed by mobilization retroperitoneal vas deferens and draw it out from external ring. There were no significant differences in lengths of vas deferens and the distances from external ring to vassal extremity between the left and right in adults. The surgical operations of vas deferens are closely related each segment of vasa.

We presented one case of 43 years old man with ectopic ureter entering the seminal vesicle associated with ectopic renal dysplasia. He had complained of perineal and lower abdominal discomfort, hemospermia. The definite diagnosis was made by seminal vesiculogram through vas deferens. We report the case with brief review of literatures.

This study was designed to determine the effect of electrical field stimulation (EFS) and adrenergic agonist on the contractility of vasectomized prostatic and epididymal segments at postvasectomized 2, 5 and 10 weeks, and to observe innervation changes of the vas deferens after vasectomy. The contractile response was recorded on a polygraph via force transducer and expressed as the g tension per 100 mg tissue. And we reviewed histopathologic sections stained with S-100 protein by light microscopy. The results were as follows: 1. In control groups, contractile responses of prostatic and epididymal segments to EFS (4, 8, 16, 32 &64 Hz) were gradually increased by increasing frequencies. But contractile responses of vasectomized epididymal segments to all frequencies of EFS declined. Contractile responses of vasectomized prostatic segments were significantly greater than that of vasectomized epididymal segments (p<0.05). 2. Contractile responses of epididymal segments to phenylephrine hydrochloride 0.00001M were significantly greater than that of prostatic segments (p<0.05). Contractile responses of prostatic segments were tend to decline. In epididymal segments, contractile response of post-vasectomized 5 weeks group was significantly greater than that of control and post-vasectomized 2 weeks groups (p<0.05). 3. In control and vasectomized prostatic segment, nerve bundles were strongly positive and intact histopathologically for the S-100 protein immunohistochemical stain. In epididymal segment, nerve bundles were intact in control group. However, vacuolar degeneration tend to be gradually increased and stained weakly by increasing duration in vasectomized epididymal segment. These results suggest that the progression of degenerative change of adrenergic innervation after vasectomy may play an important role in progressively decreasing contractility of the vas deferens after vasectomy.

PURPOSE: The proper functioning of all smooth muscle structures depends on the ability of normal blood to deliver oxygen and nutrients to the muscles. In addition, hypoxia has been shown to inhibit the contractile response to various forms of stimulation. The contractile response of the vas deferens can be divided into two phases: an initial rapid increase in tension(phasic contraction) and prolonged period of sustained tension(tonic contraction). The aim of this study was to determine the effect of hypoxia on the ability of the vas deferens to sustain tension . MATERIALS AND METHODS: The isolated strips of rat vas deferens were studied for Isometric tension measurement under normoxia and hypoxia in the organ chamber. Effects of phenylephrine(Phe) and acetylcholine(Ach) on the rat vas deferens tissue were monitored under normoxia and hypoxia. RESULTS: The results of these studies can be summerized as follows; (1) hypoxia induced time dependent decrease in both phasic and tonic contraction in response to electrical field stimulation(4 and 32Hz). The rate of inhibition of the tonic contraction was significantly and immediatly greater than that of the phasic contraction in both the prostatic and epididymal vas deferens, which was much prominent. (2) hypoxia(5min) increased the basal tension of prostatic vas deferens only to Phe(10(-3)M) and Ach(10(-3)M). But In the response of epididymal vas deferens to Phe(10(-3)M) and Ach(10(-3)M), rhythmic contractions disappeared. CONCLUSIONS: In conclusion, the contractile response of rat Vas deferens to electrical field stimulation under hypoxia were decreased and basal tension of prostatic vats deferens to Phe(10(-3)M) or Ach(10(-3)M) was increased This effect can interfere the sperm expulsion by changing normal contractability of the vas deferens.
