1/25. Testicular proximity can induce gubernaculum formation after delivery.PURPOSE: This paper presents the hypothesis that after delivery as late as 38 weeks' gestation, a testis placed near the internal ring can induce the formation of a gubernaculum and undergo a belated but otherwise normal descent. methods: Two boys with a gastroschisis were each born with one of their testes prolapsed through the defect. The testis was sutured just lateral to the deep inferior epigastric vessels at the time of the primary closure of the gastroschisis. RESULTS: One boy born at 34 weeks had his left testis prolapsed through a left-sided gastroschisis defect. At 3 months, he was admitted to the hospital with a large left inguinal hernia. The repair was complicated by the presence of a large mass of jellylike tissue extending through the internal ring to the upper scrotum. A second boy was born at 38 weeks' gestation. The testis made its way uneventfully into the right hemiscrotum by 10 months of age. CONCLUSION: These cases suggest that testicular proximity is a critical factor in the formation of the gubernaculum and that the testis can induce the formation of the gubernaculum as late as 38 weeks gestation.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/25. Agenesis of internal carotid artery associated with congenital anterior hypopituitarism.We report a rare case of unilateral agenesis of the internal carotid artery in association with congenital anterior hypopituitarism. The collateral circulation is supplied by a transsellar intercavernous anastomotic vessel connecting the internal carotid arteries. These abnormalities are well depicted on MRI and MRA. The agenesis of the internal carotid artery may explain the pathogenesis of some of congenital anterior hypopituitarism.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/25. Intra-abdominal testis with loop-like epididymis and intra-canalicular vas and vessels.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.- - - - - - - - - - ranking = 8keywords = vessel (Clic here for more details about this article) |
4/25. Impact of laparoscopy on the management of an unusual case of nonpalpable testis in an adult patient.BACKGROUND: In the past decade, cryptorchidism has generally been treated in the first 36 months of life using an inguinal approach, in the case of palpable testis, or using laparoscopy, in the case of nonpalpable testis. Nevertheless, before this period some children were managed incorrectly. This case report shows how laparoscopy and the collaboration between pediatric surgeons and urologists may lead to optimal results. CASE REPORT: A 19-year-old male was referred to our unit following routine medical examination for enrollment in the military service with a diagnosis of right cryptorchidism. The clinical history showed the anamnesis of right cryptorchidism diagnosed at birth as a right nonpalpable testis, confirmed at 2 years of age with clinical examination and computer tomography. The patient came to our attention to again undergo a clinical examination, ultrasonography, computed tomography, and magnetic resonance imaging. We found a left, well-positioned testis of 20 ml in volume and an empty right scrotum; all the instrumental examinations were negative. The patient was thus scheduled for a diagnostic laparoscopy. A pediatric surgeon with extensive experience in this pathology performed the procedure. The 10-mm 30 degrees optics introduced through the umbilicus showed a closed right inguinal ring, with no evidence of either vas deferens or inner spermatic vessels at the level of the inguinal region or pelvis. Two more trocars were introduced and a testis of 15 ml in volume was found under the ascending colon 10 cm away from the cecum. An orchiectomy was performed via laparoscopy. CONCLUSION: This case clearly shows that some males with nonpalpable testis may have been treated incorrectly in the prelaparoscopic era and may now have an intraabdominal testis. In addition, our experience shows that intraabdominal testis may sometime be in an unusual location, and a laparoscopic surgeon with experience in this pathology is fundamental to finding the testis. In the case of adults with nonpalpable testis, when echography, computed tomography, and magnetic resonance imaging are not useful, the only effective diagnostic procedure is laparoscopy.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/25. Multinucleated spermatogonia in cryptorchid boys: a possible association with an increased risk of testicular malignancy later in life?At birth, undescended testes contain germ cells, but after 1 year of life, a reduced number of germ cells is generally found. Microlithiasis and carcinoma-in-situ-testis occur in cryptorchid boys. Multinucleated germ cells, including at least 3 nuclei in the cell, exist in impaired spermatogenesis and in the senescent testis. AIM OF THE STUDY: We investigated whether multinucleated spermatogonia were present in undescended testes of cryptorchid boys, and if such a pattern is associated with special clinical features. RESULTS: Multinucleated spermatogonia occurred in 13/168 (8%) of 163 consecutive cryptorchid boys, who underwent surgery for cryptorchidism with simultaneous testicular biopsy showing seminiferous tubules. The patients with multinucleated spermatogonia more often exhibited a normal germ cell number (Fisher's exact test, p<0.0005), and were younger at surgery (Mann Whitney, p<0.005) than the rest of the patients. Before surgery, 3 patients underwent treatment with erythropoietin because of renal failure. An intra-abdominal testis underwent clipping and division of the spermatic vessels, and a biopsy at final surgery 7 months later, exhibited multinucleated spermatogonia. In 1 case the undescended testicular position, a fixed retraction, was acquired after surgery for an inguinal hernia. Multinucleated spermatogonia were found in cases of carcinoma-in situ-testis in 2 cryptorchid boys. No case of multinucleated germ cells appeared in our normal material. CONCLUSION: Multinucleated spermatogonia are a further abnormality present in cryptorchidism. The cryptorchid boys with multinucleated spermatogonia in general exhibited rather many germ cells. This feature may be associated with an increased risk of testicular malignancy later in life, and we propose a careful follow up regime in these cases including ultrasound examination and a testicular biopsy in cases of symptoms or clinical findings.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/25. Laparoscopic assessment and treatment of non-palpable testis in an 18-year-old male.laparoscopy, both diagnostic and therapeutic, has been used in the management of pediatric non-palpable testes. We report a case of left non-palpable testis at the unusual age of 18 years. Laparoscopic exploration revealed an intra-abdominal testis lying between the internal inguinal ring and external iliac vessels. The testis was visually in good condition and, in contrast to the accepted procedure of orchiectomy performed in late adolescent cryptorchidism, we decided to preserve this intra-abdominal testis, which was located too far from the scrotum for a primary orchidopexy. The first stage of the Fowler-Stephens procedure was performed laparoscopically. The second-stage orchidopexy was performed successfully through an inguinal approach 3 months later, after sonographic ascertainment of non-decreased testicular volume. laparoscopy allows thorough exploration for an intra-abdominal testis, with simultaneous therapeutic options. Our experience highlights the feasibility of laparoscopic assessment and treatment of cryptorchidism in adolescents and young adults.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/25. Urogenital nonunion--the case for laparoscopy for the impalpable testis.A case of urogenital nonunion is presented to illustrate the importance of laparoscopy for the impalpable testis. A 4-year-old boy with an impalpable left testis underwent laparoscopy. This revealed not only the vas deferens entering the deep inguinal ring but also a small intraabdominal testis supplied by the testicular vessels. Exploration of the inguinal canal revealed the vas deferens terminating in a nubbin of tissue. histology identified epididymal structures both adjacent to the testis and in the terminal nubbin of the vas deferens. This is an example of urogenital nonunion. Complete separation of the vas and testis with epididymal structures attached to each is very unusual, with only four other cases reported. laparoscopy should be the initial procedure for impalpable testis. A blind-ending vas deferens found on exploration of the inguinal canal might be taken as evidence of the vanishing testis syndrome. However, this conclusion should not be drawn unless laparoscopy has demonstrated testicular vessels entering the internal inguinal ring.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
8/25. Missed testis on laparoscopy despite blind-ending vessels and closed processus vaginalis.laparoscopy has become a preferred technique to evaluate a nonpalpable testis. It gives excellent visualization of the anatomy to differentiate a viable or absent testis. We present a case of an intra-abdominal testis that was missed on diagnostic laparoscopy. Despite a closed processus vaginalis, an absent vas deferens, and blind-ending vessels above the internal ring, the testis was missed.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
9/25. Surgical correction of abdominal testes after Fowler-Stephens using the neodymium: YAG laser for preliminary vessel dissection.Two boys with high undescended testes were submitted to laparoscopic laser transsection of the internal spermatic vessels. Subsequently strong collaterals developed. Definitive scrotal transfer was performed six weeks later through an inguinal incision. Two and a half years later, the testes had recovered very well. Their volume had increased markedly, and further development was normal.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
10/25. Congenital testicular lymphangiectasis.Testicular lymphangiectasis are described for the first time in a patient with bilateral inguinal cryptorchidism. A great number of irregular lymphatic channels was observed within the parenchyma and the tunica vasculosa in both testes. Large and numerous anastomosis between the lymphatic vessels of these two areas could also be seen. The MTD and the TFI of the left testis were normal. Both parameters were very low in the right testis. The association of this fact with the greater development of the lymphatic vessels in this testis strongly supports the idea that testicular lymphangiectasis interfere mechanically with the testis tubular development.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
