1/58. infertility treatment in autosomal dominant polycystic kidney disease (ADPKD)--a case report.Autosomal dominant polycystic kidney disease (ADPKD) is a frequently occurring inherited condition with cysts in many organs including the kidneys. However, a combination of seminal vesicle cysts, cystic obstruction of ejaculatory duct and ADPKD is rarely encountered. The following case report presents an infertile ADPKD patient who had seminal vesicle cysts and ejaculatory duct cyst, and describes the treatment by transurethral resection of the ejaculatory duct.- - - - - - - - - - ranking = 1keywords = duct, obstruction (Clic here for more details about this article) |
2/58. Vasitis nodosa: immunohistochemical findings--case report.We report the immunohistochemical features of vasitis nodosa and discuss the differential diagnosis. The patient was a 42-year-old Japanese man with bilateral small indurations of the vas deferens at the site of a previous vasectomy. Microscopically, small-sized ducts proliferated within the muscular wall of the vas deferens, and focally in the surrounding connective tissue. Immunohistochemically, most proliferating glandular cells were strongly positive for cytokeratins 7, 19, and 34betaE12, and vimentin. Epithelial membrane antigen and Leu-M1 reacted against the luminal surface of the cells. Focally, glandular cells were also positive for CA125. Cytokeratin 20, carcinoembryonic antigen, and prostate-specific antigen were negative. We discuss the immunohistochemical differentiation of vasitis nodosa from prostatic adenocarcinoma, adenocarcinoma of the rete testis, and adenomatoid tumor.- - - - - - - - - - ranking = 0.29268925185274keywords = duct (Clic here for more details about this article) |
3/58. All-trans-retinoic acid-induced scrotal ulcerations in a patient with acute promyelocytic leukemia.Induction therapy with all-trans -retinoic acid has been shown to improve the outcome of patients with acute promyelocytic leukemia, although some side effects occur. Dry skin and lips are among the most common cutaneous side effects. We report a case of scrotal ulcerations induced by all-trans -retinoic acid in an American patient; to our knowledge this is the first such case reported.- - - - - - - - - - ranking = 0.29268925185274keywords = duct (Clic here for more details about this article) |
4/58. Scrotal ulceration during all-trans retinoic (ATRA) therapy for acute promyelocytic leukaemia.We report the development of painful scrotal ulceration in two patients during treatment with all-trans-retinoic acid (ATRA) for acute promyelocytic leukaemia (APL). ATRA 45 mg/m2 was administered orally for 8 days prior to the addition of standard induction chemotherapy. Painful scrotal ulceration developed in both cases within 2 weeks of therapy (9 and 13 days) and responded slowly to drug withdrawal and systemic, or topical, corticosteroids. A total of 17 APL patients have been treated with ATRA at our institution during the last 10 years, giving an incidence of approximately 12%. The present report, together with a review of literature, suggests that scrotal ulceration is a specific adverse effect of ATRA therapy and that this complication may be more common than previously documented.- - - - - - - - - - ranking = 0.29268925185274keywords = duct (Clic here for more details about this article) |
5/58. Dystrophic scrotal calcinosis originating from benign eccrine epithelial cysts.Scrotal calcinosis has been classified as a form of idiopathic calcinosis cutis. However, the pathogenesis of the calcified nodules has not been fully elucidated: it is still unclear whether the condition is truly idiopathic, or the result of breakdown of calcified epithelial cysts. We describe a 29-year-old Japanese patient with scrotal calcinosis originating from epithelial cysts. light microscopy revealed a large epithelial cyst containing von Kossa-positive material and several small dilated ductal structures beside the cyst. The epithelia of the cyst and ductal structures were connected, showing similar eccrine duct differentiation on immunohistochemical staining and electron microscopy. In the cyst lumen, calcium was present as needle-shaped crystals. The pathogenetic mechanism of calcium deposition seemed to be due to excessive production and discharge of matrical debris and sulphated mucopolysaccharides, which derived from luminal cells, and their accumulation in the lumina.- - - - - - - - - - ranking = 1.170757007411keywords = duct (Clic here for more details about this article) |

7/58. Laparoscopic management of retrovesical cystic disease: washington University experience and review of the literature.BACKGROUND AND PURPOSE: Recently, the laparoscopic approach to the management of seminal vesicle cysts has been described. This report outlines the washington University experience and reviews the present literature to evaluate the results of the laparoscopic approach to the excision of retrovesical cysts of seminal vesicle and Mullerian origin. patients AND methods: The hospital and office records of three patients undergoing laparoscopic excision of seminal vesicle and Mullerian duct cyst disease between April 1993 and March 1999 were reviewed for the operative time, the estimated blood loss, total hospital stay, total analgesia required postoperatively, the time to resumption of oral intake, and the postoperative recovery. A literature search revealed two additional reports of laparoscopic management of cystic disease of the seminal vesicle, comprising only one and two patients. An additional review of the literature was performed to compare the laparoscopic procedure with the transvesical, transurethral, open transvesical, and open retrovesical approach for the management of the disease. RESULTS: For the three patients at washington University, the operative time averaged 4 hours (range 1.8-6.1 hours), and the mean estimated blood loss was 150 mL (range 50-200 nL). The patients required a mean of 43 mg of morphine sulfate for postoperative pain control, had a mean hospital stay of 2.6 days, and resumed oral intake 5.8 hours postoperatively. In combination with the three other cases reported in the literature, the average operative time for laparoscopic retrovesical cyst excision was 2.9 hours, and the average hospital stay was 2.2 days. With an average follow-up of 17 months, all six patients had excellent resolution of their preoperative symptoms. There have been no major or minor complications or any need for further operative therapy. CONCLUSION: Laparoscopic excision of retrovesical cystic disease is an effective surgical procedure, associated with minimal postoperative morbidity, short hospitalization, and a rapid recovery for the patient.- - - - - - - - - - ranking = 0.29268925185274keywords = duct (Clic here for more details about this article) |
8/58. Endoscopic extraction of an ejaculatory duct calculus to treat obstructive azoospermia.Calculous obstruction of an ejaculatory duct is an uncommon cause of azoospermia or low-volume oligospermia in the infertile man. We report the case of a 32-year-old man with azoospermia, low ejaculate volume, and transrectal ultrosonography (TRUS) findings of bilateral seminal vesicle distention. On cystoscopy for planned transurethral resection of the ejaculatory ducts, a calculus obstructing the right ejaculatory duct at the verumontanum was discovered and removed. Three months later, semen analysis showed improvements in volume, sperm concentration, and sperm motility. An ejaculatory duct calculus should be included in the differential diagnosis of obstructive azoospermia or low-volume oligospermia. magnetic resonance imaging or TRUS may be advisable to identify ductal calculi.- - - - - - - - - - ranking = 2.7561355111165keywords = duct, obstruction (Clic here for more details about this article) |
9/58. Primary sclerosing lipogranuloma with broad necrosis of the scrotum.A-25-year-old man was admitted because of a painless tumor of the scrotum. The patient denied a history of exogenous material injection and trauma in the scrotum. Physical and radiological examination revealed a mass in the scrotum, and blood laboratory tests showed no significant findings except for mild eosinophilia (5.6%). Resection of the mass was performed. The mass was isolated and located in the subcutaneous tissue of the scrotum. The mass was rectangular and symmetrical, and measured 65 x 45 x 15 mm. Histologically, the mass was composed of adipose tissue with fibrosis. Many epithelioid granulomas with multinucleated giant cells of foreign body and Langhans' types and heavy infiltrates of lymphocytes and eosinophils were recognized. Characteristically, the lesion showed broad coagulative and lytic necrosis. Congestion and edema suggestive of ischemia were seen in some areas. Special stains for acid-fast bacteria, gram-positive bacteria and fungi failed to detect any microorganisms. polymerase chain reaction for mycobacterium tuberculosis revealed no reaction products. Immunohistochemically, the majority of lymphocytes were CD45RO-positive T cells, and S-100 protein-positive cells and CD68-positive macrophages were scattered in small amounts. The appearances were typical for sclerosing lipogranuloma except for the necrosis. Although the pathological mechanism of the broad necrosis is unclear, the necrosis might be the result of ischemia. Our case suggests that primary sclerosing lipogranuloma of the scrotum might show broad necrosis, and that T-cell-mediated immune response might play a part in the formation of lipogranuloma.- - - - - - - - - - ranking = 0.29268925185274keywords = duct (Clic here for more details about this article) |
10/58. Scrotal abscess originating from appendicitis: a case report.There are numerous reports concerning the presentation of appendicitis as a urologic problem. However, scrotal abscess originating from appendicitis has rarely been described. We report a right scrotal abscess due to a preceding retroperitoneal abscess originating from retrocecal appendicitis. The scrotal abscess developed progressively following appendectomy. Scrotal exploration was carried out under the presumptive diagnosis of abscessed epididymo-orchitis. However, the patient remained febrile and had productive pus drained from the scrotum after exploration. Abdominal computerized tomography demonstrated that a large retroperitoneal abscess had accumulated at the appendectomy site. Percutaneous drainage of the retroperitoneal abscess resulted in resolution of the scrotal abscess. In cases of scrotal abscess following previous abdominal events (e.g. appendectomy), we recommend that abdominal origins should be carefully surveyed before scrotal exploration.- - - - - - - - - - ranking = 0.29268925185274keywords = duct (Clic here for more details about this article) |
