ESWL monotherapy has been considered a valid initial treatment for staghorn calculi. In an effort to reduce post-ESWL obstruction, many urologists place ureteral stents before ESWL. The use of ureteral stents has proved to contribute to successful stone passage and to reduce post- ESWL morbidity but there also have been reports of complications that might have been caused by indwelling ureteral stents. From January 1989 to December 1995, we reviewed 29 patients with ureteral obstruction after ESWL (EDAP LT-01 & 02) monotherapy without ureteral stenting in 47 patients with staghorn calculi. Ureteral obstruction was occurred in 29 patients (61.7%); 16 (55.2%) in the upper ureter, 11 (37.9%) in the lower ureter, and 2 (6.9%) in the mid-ureter. Steinstrasse was occurred in 13 patients (13/29, 44.8%); 8 (61.5%) in the lower ureter, 4 (30.7%) in the upper ureter, and 1 (7.7%) in the mid-ureter. Ureteral obstruction was occurred regardless of the size of the staghorn calculi(length, breadth, volume). The method of resolving ureteral obstruction was additional ESWL (21 patients, 72.4%), and auxillary procedures including PCN (4 patients, 13.8%), push up procedure (1 patient, 3.4%), push up & double J stenting (1 patient, 3.4%), and ureterolithotomy (2 patient, 6.9%). Mean number of session of ESWL resolving ureteral obstruction was 3.27. Overall complete stone-free rate of staghorn calculi was 55.3%(26 patients). Our results indicate that postoperative ureteral obstruction is easily relieved without major complication by additional ESWL or auxillary procedures. Therefore, ie believe that ESWL monotherapy without ureteral stenting may be adequate treatment modality of staghorn calculi.

We reviewed the result of one-stage hypospadias repair of 32 cases, from Jan. 1989 to Dec. 1994, according to the site of urethral opening after release of chordee. The following results were obtained. 1. The posterior hypospadias (posterior penile, penoscrotal) was 18 cases and the anterior & middle hypospadias was 16 cases. 2. Success rate of posterior hypospadias repair was 9/18(50%) and that of anterior & middle hypospadias was 9/16(56.3%), it was not different statistically (P<0.05). 3. Complication rate of posterior hypospadias repair was 9/18 (50%) and of anterior & middle hypospadias was 7/16(43,5%), it was not different statistically (P<0.05) and complications were managed by simple procedure and require no further treatment. In condition, one stage repair of hypospadias could be applicable in most cases of hypospadias. The complication and morbidity were minimal.

Fibrous histiocytoma are complex group of tumors that feature cells resembling fibroblasts and histiocytes.In a case of fibrous histiocytoma involving the cornea and corneolimbus, we evaluated the finding of H-E, Masson-trichrome, reticulin, CD68, alpha-1-antitrypsin antibody and smooth muscle actin antibody stain after the localized excision in 26 years old male patient. In H-E stain, tumor cell included many multinucleated giant cells having abundant eosinophilic and foamy cytoplasm infiltreated by numerous lymphocyte, CD68 & alpha-1-antit-rypsin antibody staining resulted in diffuusely positive finding. Therefore examination. Good result was noted after complete excision at 6 month follow-up.

The hyperosinophilic syndrome (HES) commonly involves liver and spleen but only a few literature has reported the imaging features. In this article, we present the imaging features of the liver and spleen in HES patients together with clinical and laboratory features. This study included 5 HES patients with hepatic involvement. Extensive laboratory tests including multiple hematologic, serologic, parasitologic, and immunologic examinations were performed. Imaging studies included CT, ultrasound (US) of upper abdomen and hepatosplenic scintigraphy. All patients were periodically examined by laboratory and imaging studies for 4 to 24 months. The common clinical presentations were weakness, mild fever, and dry cough. All patients revealed leukocytosis with eosinophilia of 40 to 80% and benign eosnophilic hyperplasia of the bone marrow. The percutaneous biopsy of the hepatic focal lesions performed in 2 patients showed numerous benign eosinophilic infiltrates and one of them revealed combined centrilobular necrosis of hepatocytes. All cases revealed hepatomegaly with multiple focal lesions on at least one of CT, US, or scintigraphy. These findings completely disappeared in 2 To 6 months following medication of corticosteroid or antihistamines. The HES involved the liver and CT, US, or scintigraphy. These findings completelydisappeared in 2 to 6 months following medication of corticosteroid or antihistamines. The HES involved the liver and CT, US, or scintigraphic studies showed hepatic multifocal lesions with hepatomegaly. Differential diagnoses of these findings should include metastatic disease, lymphoma, leukemia. candidiasis or other opportunistic infections.

Primary role of ultrasound in patients with thyroid nodule is to determine the multiplicity and detect occult carcinoma. We analyzed US findings of 53 thyroid carcinomas with multiple nodular lesions from january 1988 to december 1991. The results were as follows: 1. 109 malignant nodules in 53 cases and 24 benign in 23 were comfirmed. 2. The nature of the masses were solid in 72 malignant nodules (74.2%), and complex in 25 (25.8%) of which 19 were predominantly solid. 3. The echo pattern of the solid and solid predominant masses were hypoechoic in 78 malignant nodules (80.4%), hyperechoic in 10 (10.3%), and isoechoic in 3 (9.3%) 4. Internal punctate calcifications within the masses were observed in 31 malignant nodules (31.9%). 5. Halo sign was present in 16 malignant nodules(16.5%). 6. The preoperative sonographic diagnosis of thyroid carcinoma was made in 39.4% of 53 cases with multiple nodules on US. In conclusion, the number, and halo formation of nodules were insignificant to differentiate the benign nodule from the malignant. The heterogeneous hypoechoic nodules with size greater than 4cm, multiple stippled calcifications, displacement of the trachea or other surrounding structures of combined lymph node enlargements seem to indicate the possibility of malignancy.
