Diagnosis and differential diagnosis value of ultrasound in epididymal mass / 中华男科学杂志

<p><b>OBJECTIVE</b>To elevate the diagnosis and differential diagnosis levels of epididymal mass by sonography.</p><p><b>METHODS</b>This was a retrospective study of 179 cases of epididymal mass treated by surgery in our hospital between 1990 and 2005. The analysis was focused on pathological and sonographic features.</p><p><b>RESULTS</b>179 patients with mean age of 51.4 +/- 14.7 were enrolled. The epididymal mass was classified into four groups: epididymal cyst (n = 98), nonspecific epididymitis (n = 27), tuberculous epididymitis (n = 33) , and epididymal tumor (n = 21). Epididymal cyst could be easily diagnosed by ultrasound, the diagnostic rate was 93.8%, but nonspecific epididymitis and tuberculous epididymitis were hard to differentiate, complicating with multiple organs lesions may distinguish tuberculous from nonspecific epididymitis. Tuberculous epididymitis could be easily diagnosed when cold abscess, calcification and sinus tract emerged. The majority epididymal tumors were benign, and malignant cases were rarely seen. Patient's history, physical examination and sonographic features were all essential to make a right diagnosis.</p><p><b>CONCLUSION</b>Ultrasound features may be helpful to the differential diagnosis of epididymal mass and ultrasound should be the first choice of image detection in epididymal lesions.</p>

Ultrasound guided percutaneous puncture and sclerotherapy with alcohol for peripelvic cysts / 中华外科杂志

<p><b>OBJECTIVE</b>To summarize the experience of ultrasound guided percutaneous aspiration and sclerotherapy for peripelvic cysts and investigate the clinical effect.</p><p><b>METHODS</b>A total of 169 cases of peripelvic cyst patients were evaluated, of whom 36 cases (21.3%) had hydronephrosis secondary to peripelvic cysts, 8 cases (4.7%) had renal calculus. All patients underwent ultrasound and intravenous phelography (IVP) examination, 59 patients also had CT scan. Hydatid fluid was analyzed by amine test. Percutaneous aspiration was guided by ultrasound, 95% alcohol was used to sclerosis the peripelvic cysts when amine test was negative or positive but did not have communication with pelvis through opacification. Ultrasound were done at 1, 3, 6 months and every 1 year thereafter, follow-up period were 6 months to 5 years.</p><p><b>RESULTS</b>One hundred and sixty-five peripelvic cysts (97.6%) were cured by once sclerotherapy, the diameter of another 4 cases (2.4%) diminished to less than 1.5 cm by once sclerotherapy. Thirty-six cases of hydronephrosis were all resolved after sclerotherapy. Eight cases had renal calculus, of whom 4 cases underwent extracorporeal shockwave lithotripsy, 2 cases underwent percutaneous nephrolithotomy, and 2 cases did not treat the stone. Five patients had gross hematuria after aspiration, but all diminished in 3-5 d.</p><p><b>CONCLUSION</b>Ultrasound guided percutaneous aspiration and sclerotherapy for peripelvic cysts had the superiority of safety, effectiveness micro-invasion and low complication.</p>
