The lacrimal fossa can be invovled by a wide specturm of orbital pathology. The correct diagnosis is importantto avoid unnecessary procedure and to do appropriate management. 14 patients with mass lesions in the lacrimalfossa were evaluated with CT and clinical findings. The results were as follows: 1. Final diagnosis of 14 caseswith lacrimal fossa tumors was pleomorphic adenoma in 3 cases, adenoid cystic carcinoma in 1 case, pseudotumor incases, lymphoma in 2 cases, neurofibroma in 1 case, chloroma in 1 case and metastatic adenocarcinoma in 1 case. 2.The duration of symptoms of pleumorphic adenoma was more than 1 year and characteristic CT findings were globularmasses with pressure erosion of the adjacent bone. Patient wih adenoid cystic carcinoma had a short history ofsymptoms. CT showed a fusiform mass but intracranial extension with frank destruction of sphenoid bone. 3.Patients wtih pseudotumor and lymphoma had symptoms for less than 1 year. The CT findings were ill-definedinfiltrative patterns with scleral thickening and the differential diagnosis of them was difficult. 4. The marginsof neurofibroma and chloroma were well defined while that of the metastatic adenocarcinoma was ill-defined. 5. Thedegree and the extent of the contrast enhancement gave no benefit in the differential diagnosis of each diseaseentities and even of the benign and malignant lesions.

Purpose: The aim of this study was to conduct research on the pre- treatment prognostic factors that may influence the continuation or cessation of adrenergic alpha-antagonist (alpha-blocker) in benign prostatic hyperplasic (BPH) patients. Materials and Methods: 56 patients who were responsive to alpha-blocker, and returned for follow-up for more than 5 months, were evaluated. The patients in whom the therapeutic effect persisted for more than 8 and for less than 4 weeks after cessation of alpha-blocker were designated as groups 1 (29 patients) and 2 (27 patients), respectively. An evaluation between the groups, based on age, prostate specific antigen (PSA), total prostate volume (TPV), transition zone volume (TZV), transition zone index (TZI), International Prostate Symptom Score (I-PSS), quality of life (QoL index), peak flow rate (Qmax), residual urine, and the duration of treatment, was conduct. All parameters were initially checked before medication. Results: This study showed that younger age, lower PSA level, smaller volume of residual urine and higher Qmax were useful indicators on the persistency of the therapeutic effect. However, TPV, TZV, TZI, I-PSS, QoL index and the duration of treatment did not affect the outcome. Conclusions: It was concluded that age, PSA, Qmax and residual urine measured before medication were useful pre-treatment prognostic factors in the prediction of the persistency of the therapeutic effect after cessation of alpha-blockers.

Color Doppler ultrasonography was performed in 41 patients with the acute onset of scrotal pain. of the 32 cases of 33 inflammatory diseases (epididymitis n=19, epididymo-orchitis n=12, orchitis n=1) color Doppler image demonstrated increased epididymal or testicular flow. Color Doppler ultrasonography correctly predicted the need for surgery in 5 of 9 operated patients and correctly predicted the outcome in all 32 nonoperated patients. In the two cases of 3 detorsions which were evident in color Doppler ultrasonography was incorrectly diagnosed with testis scintigraphy. Color Doppler ultrasonography is more effective than testis scintigraphy. Results show that color Doppler ultrasonography helps accurately correlate anatomy and perfusion in real time and may prove to be the definitive imaging technique for the diagnostic evaluation of the acute scrotum.

A retroperitoneal lymphangioma is a rare tumor, most commonly affecting the neck or axillary area. We report a case of a 60-year-old man, with left flank pain, who had a retroperitoneal cavernous lymphangioma, with hemorrhagic complication. The diagnosis was made after complete excision of the tumor, followed by pathologic documentation.

PURPOSE: When performing partial nephrectomy, there is a risk of excessive blood loss; this necessitates transfusion and it also results in deterioration of the renal function when a vascular clamp is used. We evaluated the usefulness of the microwave tissue coagulator for performing partial nephrectomy for renal cell carcinoma and benign renal tumors. MATERIALS AND METHODS: From October 2000 to January 2005, partial nephrectomy was performed without renal pedicle clamping with using the microwave tissue coagulator for 9 patients with seven renal cell carcinomas and two angiomyolipomas. RESULTS: In 6 patients, partial nephrectomy was successful with using the microwave tissue coagulator without renal pedicle clamping. The mean operative time and blood loss were 184 minutes and 223ml, respectively. For the remaining cases, three had positive tumor margins, so radical nephrectomy was performed for those cases. The mean creatinine level was not increased postoperatively. The mean preoperative and postoperative hemoglobin levels were 12.6g/dl and 11.7g/dl, respectively. CONCLUSIONS: Partial nephrectomy with using the microwave tissue coagulator can be safe and successful without performing renal pedicle clamping. However, the insertion line of the microwave electrode must be carefully determined for the resection to be curative, the same as when making the cut line for conventional partial nephrectomy.
