Intra-abdominal testis with loop-like epididymis and intra-canalicular vas and vessels

INTERNATIONAL JOURNAL OF UROLOGY, Issue 9 2002
AHMED ANWAR
Abstract A case of intra-abdominal testis with loop-like epididymis and intra-canalicular vas and vessels is presented. A 3-year-old male with left impalpable testis since birth was admitted to our department. Physical examination and ultrasonography were inconclusive. Laparoscopy revealed a small left abdominal testis with surrounding adhesions close to the left-obliterated umbilical artery. The vas deferens and spermatic vessels were entering into the internal inguinal ring. The processus vaginalis was patent. At inguinal exploration the testis was atrophic and the epididymis was loop-like, joining the vas deferens in the inguinal canal. The spermatic vessels continued to the atrophic testis in a loop-like manner. The testis, epididymis and the vas deferens were removed. Histopathological examination of the testis revealed Sertoli cells only. If inguinal exploration had been performed without laparoscopy, the presence of the vas deferens and spermatic vessels in the inguinal canal with the absence of the testis could have been misdiagnosed as vanishing testis. Abdominal testis would thus have been missed, with increased risk of complications, particularly malignancy. [source]

Diagnosis and treatment of post-herniorrhaphy vas deferens obstruction

INTERNATIONAL JOURNAL OF UROLOGY, Issue 2000
Tadashi Matsuda
Childhood inguinal herniorrhaphy (IH) is one of the most frequent causes of seminal tract obstruction. The incidence of vasal obstruction was found to be as high as 26.7% in subfertile patients with a history of childhood IH. The distal end of the vas deferens was found at the internal inguinal ring or in the pelvic cavity in 56.7% of cases, more than 3 cm of the vas deferens had been resected in 37.9% of cases, and sperm was found in vasal fluid in 45.5% of cases during corrective surgery. Microsurgical two-layer vasovasostomy resulted in the postoperative appearance of sperm in 39% of patients. In patients with postoperative azoospermia, a secondary epididymal obstruction caused by a long-term vasal obstruction is a highly probable cause. Ipsilateral epididymovasostomy following successful inguinal vasovasostomy results in the postoperative appearance of sperm in the ejaculate in 100% of the patients and a subsequent natural pregnancy rate of 50%. The overall pregnancy rate among couples, following surgery in 18 patients, was 43%, excluding pregnancies achieved by in vitro fertilization or intracytoplasmic sperm injection. Microsurgical reanastomosis of the seminal tract resulted in high impregnation rates among partners of patients with seminal tract obstruction caused by childhood IH. After receiving sufficient information on each treatment modality, patients can choose their preferred treatment, either reanastomosis of the seminal tract or assisted reproductive technology using epididymal or testicular sperm.

Measurement of the linear dynamics of the descent of the bovine fetal testis

JOURNAL OF ANATOMY, Issue 1 2003
M. J. Edwards
Abstract Measurements were made on 86 male bovine fetuses collected from abattoirs in the vicinity of Sydney, Australia. The fetal body length was used to calculate the approximate day of gestational age (DGA); most fetuses were between 60 and 150 DGA. The distances from the caudal pole of the kidney (metanephros) to, respectively, the tip of the scrotum, the distal end of the testis and the internal ring of the inguinal canal were measured, as well as the dimensions of the testis and gubernaculum testis. Distances of (1) testis to inguinal canal, (2) inguinal canal to scrotum, (3) testis to scrotum and (4) gubernaculum to scrotum were calculated from these measurements, which were made on both left and right sides. The total length of the gubernaculum testis increased during transabdominal passage and during transinguinal passage of the testis. Furthermore, the gubernaculum appeared to maintain the testis at a relatively fixed distance from the scrotum during transabdominal passage so that the inguinal canal appeared to move towards the testis. The greatest distance between the testis and the tip of the scrotum was found during the transinguinal passage of the testis and was 2.8 cm for the left testis and 2.3 cm for the right. When located within the scrotum, each testis was still 1.6,1.7 cm from the tip of the scrotum, so the distance to be traversed was only 0.6,1.2 cm. Following passage of the testis through the inguinal canal, the gubernaculum became shorter and its distal tip was displaced toward the distal end of the scrotum. Traction by the gubernaculum could account for the final transposition of the testis from the external inguinal ring to the scrotum. Other factors involved in displacement of the testis include differential growth patterns as well as increases in the dimensions of the testis itself. [source]

Vaginal Ring and Round Ligament of the Uterus in the Female Cat

ANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 4 2009
A. Watson
Summary The peritoneum was examined for the existence of a vaginal ring and the round ligament of the uterus was dissected through the inguinal region in eleven embalmed adult female cats. In all cats, there was no evidence of a peritoneal evagination into the inguinal canal. There was no vaginal ring and no vaginal process. The round ligament of the uterus passed through the inguinal canal and disintegrated in the fascia a short distance beyond the superficial inguinal ring. [source]

Altered course of the right testicular artery

CLINICAL ANATOMY, Issue 1 2004
M. Bülent Özdemir
Abstract An unusual course of the right testicular artery was observed during routine dissection of the posterior abdominal wall of a 60-year-old male cadaver. It arose from the abdominal aorta, inferior and posterior to the origin of the right renal artery, and passed posterior to the inferior vena cava and right renal vein; it then arched anterior to the inferior pole of the right kidney and descended anterior to the psoas major muscle, crossing anterior to the genitofemoral nerve, ureter and the proximal part of the external iliac artery. Finally, it passed to the deep inguinal ring and through the inguinal canal to enter the spermatic cord with the other constituents. The left testicular artery arose from the abdominal aorta about 1 cm higher than the right testicular artery and followed a normal course. The embryologic basis and clinical importance of this case are discussed. Clin. Anat. 17:67,69, 2004. © 2003 Wiley-Liss, Inc. [source]
