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. 相似文献

Transrectal ultrasound and partial ejaculatory duct obstruction in male infertility. 总被引:6,自引:0,他引:6
Partial ejaculatory duct obstruction, due to either a congenital or an acquired cyst or ejaculatory duct stenosis secondary to calcification, chronic inflammation, can produce a wide spectrum of seminal fluid abnormalities. Sperm density may range from azoospermia to normospermia while ejaculate volume can be low to normal. Sperm motility is consistently diminished (less than 30%). We have treated 2 patients with ejaculatory duct stenosis whose diagnosis was accurately made with transrectal ultrasonography (TRUS). We now suggest that TRUS be used when there is a low semen volume (less than 1.0 cc), or low motility (less than 30%), or oligospermia (less than 20 million sperm/mL), and normal findings on physical examination with normal serum gonadotropin values in the absence of any other explanation. 相似文献

Aim: To identify and define prostate and seminal vesicle abnormalities in patients with chronic male accessory gland infection (MAGI) who failed to respond to antibacterial treatment. Methods: We selected 67 consecutive patients with MAGI and persistently elevated bacteriospermia (≥ 10^6 colony forming units [CFU]/mL) after three antibiotic courses. Fourteen infertile patients with initial chronic microbial (≥ 10^6 CFU/mL) MAGI who responded to antibacterial treatment (〈 10^3 CFU/mL) served as a control group. All patients and controls underwent transrectal ultrasonography (TRUS) scans and semen analysis. Patients with low seminal plasma volume (〈 1.5 mL) underwent both preejaculatory and post-ejaculatory TRUS examination. Results: TRUS revealed multiple abnormalities indicative of: (i) bilaterally extended prostato-vesiculitis (group A: 52 cases, 77.6%) (nine of these patients also had micro-emphysematous prostate abscess); and (ii) prostato-vesiculitis with unilateral or bilateral sub-obstruction of the ejaculatory ducts (group B: 15 cases, 22.4%). Mean sperm concentration, total sperm number, ejaculate volume and pH value were significantly higher in group A than in group B. In addition, sperm forward motility and the percentage of normal forms were significantly worse than in controls, whereas leukocyte concentration was significantly higher in group A. Group B patients had all sperm parameters, but their pH values, significantly different from those of controls. Conclusion: Although antibiotic therapy is considered suitable when microbial MAGI is suspected, it is impossible to account for a poor response to antibiotics merely on the basis of conventional criteria (clinical history, physical and ejaculate signs). Thus, TRUS may be helpful in the follow-up of these patients. 相似文献

We aimed to evaluate and compare the clinical diagnostic values of magnetic resonance imaging (MRI) and ultrasound in patients with intractable haematospermia. We performed a retrospective review of 23 patients with intractable haematospermia who were diagnosed with seminal vesicle haematocele and/or calculi by transurethral seminal vesiculoscopy (TSV). Patients’ demographics, disease durations, operative times, and MRI and transrectal ultrasound (TRUS) results were recorded. McNemar's test was used to compare the positive diagnostic rates of MRI and TRUS. All patients had undergone preoperative seminal vesicle MRI and TRUS to identify the aetiology of the haematospermia. The average age and disease duration were 39.3 years and 24.1 months, respectively. The mean operative time was 81.1 min. The positive result rates for MRI and TRUS were 95.7% (22/23) and 39.1% (9/23), respectively. Compared with TRUS, MRI had a significantly higher preoperative positive diagnostic rate (p < 0.01). These results suggest that MRI should be considered as a method for diagnosing intractable haematospermia in patients when TRUS findings are negative or inconclusive. 相似文献

Transutricular seminal vesiculoscopy 总被引:2,自引:0,他引:2
Disorders of the seminal vesicle have been evaluated mainly via imaging techniques. We developed a technique to examine the interior of seminal vesicles endoscopically. In 37 hemospermic patients, transrectal ultrasound (TRUS) or endorectal MRI were performed preoperatively. When the patients had definite abnormalities on the imaging studies and did not improve after medication over a period exceeding 3 months, transutricular seminal vesiculoscopy was performed using a 6F or a 9F rigid ureteroscope. Patients were then followed for at least 3 months. Endoscopic evaluation was also performed in two patients with stage B(1) and D(2) prostate carcinoma. In hemospermic patients, hemorrhage was found in the seminal vesicles or the ejaculatory ducts in 23 (62.2%) and 3 (8.1%), respectively. Calculi were present in the seminal vesicles or ejaculatory ducts in 6 (16.2%) and 2 (5.4%), respectively. In prostate carcinoma patients, seminal vesiculoscopy was similarly informative. Postoperative complications, including epididymitis or retrograde ejaculation, were not observed. Transutricular seminal vesiculoscopy can be performed easily with conventional endoscopic equipment and provides useful information. 相似文献
