A clinical observation was made on 96 cases of transurethral resection for the benign prostatic hypertrophy, admitted during the period of 3 years from January 1984 to December 1986. Previous to the transurethral resection of prostate, the suprapubic cystostomy was accomplished in 38 cases among them and following advantageous results were obtained. 1. Suprapubic cystostomy before TURP provides better endoscopic vision by continuous flow of irrigating fluid to permit no interrupted resection. 2. By eliminating the time spent for evacuation of the bladder, eye accommodation and reestablishment of surgical land marks, it permits transurethral resection of larger gland, within recognized safety guidelines. 3. It tends to minimize and prevent absorptive complications by lessening intravesical pressure. 4. It decreases operative risk by lessening operative time and the volume of fluid absorbed. 5. It provides an alternative route of irrigation and drainage intraoperatively and postoperatively.

Balloon-tipped, flow-directed (Swan-Ganz) catheters are used commonly for monitoring of cardiac function in patients undergoing cardiac surgical procedures. We report a case of pulmonary hypertension with hypoxemia which may be caused by incorrect positioning of pulmonary artery catheter (PAC) during CABG. Pulmonary arterial pressure (PAP) of 70/40 mmHg which was nearly high as systemic pressure was measured when we tried to wean patient from cardiopulmonary bypass. But, TEE (transesophageal echocardiography) showed nonspecific finding. PAP decreased soon and maintained about 33/16 mmHg for a few minutes. But, the PAP elevated high to 70/40 mmHg again and the arteral oxygen tension (PaO2) decreased to 61.2 mmHg. When we withdrew the PAC to the depth of 35 cm, the PAP and systolic pressure returned to normal range and PaO2 elevaed to 320 mmHg. End tidal CO2 was elevated from 30 mmHg to 35 mmHg.

The fashion of vascular anastomosis, end-to-end or end-to-side (E-to-S), are depended upon surgeon's preference or surgical situations. In E-to-S anastomosis two different methods of arteriotomy are applicable but it has been suggested the type, either elliptical or slit arteriotomy, play a different role in the flow hemodynamics. We thought that the difference is more considerable in microvascular surgery. This study examines the effects of elliptical versus slit arteriotomy on morphologic vessel patency. Twenty male Sprague-Dawley rats were divided into two groups of ten rats each. Both carotid arteries were selected as a experimental model. During the procedures the rat brain was tolerable to ischemia and all animals were survived after operations. The morphologic analysis of anastomosis site was through resin-casting method with scanning electromicroscopic examination. The results showed notable difference between two groups in three-dimensional morphology at two-month of operation. This difference may affect the flow hemodynamics and long-term vessel patency. In microvascular anastomosis, the mortpologic difference of the elliptical arteriotomy is worse than slit arteriotomy which compromises the vessel circumference.

Authors retrospectively analyzed the CT findings of cystic tumors of the mediastinum in surgically confirmed13 cases at Seoul National University Hospital during the recent 3 years from August 1980 to August 1983. Theresults are as follows: 1. Among 13 cases, bronchogenic cyst and cystic teratoma were 4 cases respectively,pericardial cyst were 2 cases, and thymic cyst and cystic hygroma was 1 case respectively. 2. CT No. of 4bronchogenic cysts was in the range of 12-112 HU, 3 cases among them had thick-walled capsules. CT No. of 4 cysticteratomas was in the range of

Fity-four patients with head and neck cancers were prospectively examined with the CT to determine its valuein staging cervical lymph nodes metastases and to compare with the clinical staging. The CT staging agreed withthe clinical staging in 61%(33/54), upgraded the clinical staging in 22%(12/54) and downgraded in 17%(9/54). Thepost-surgical confirmation was made in only 11 patients, The possible causes of disagreement between the CT andthe clinical staging, and the diagnostic value of the CT in the evaluation of the cervical nodes metastases werediscussed.

A 51 year-old male was admitted to our hospital complaining of right lower abdominal mass. Physical examination revealed nonpalpable right testicle in the scrotum. Echogram and CT scan of abdomen revealed a well defined round mass in the right lower abdomen. Exploration was performed under the suspicion of abdominal cryptorchid testicular tumor, and the mass was resected completely. The mass was 9X7X4cm in size and l90gm in weight, and cut surface of it showed yellowish-white spherical tumor nodules. Histological examination revealed seminoma. Postoperative right pelvic and retroperitoneal irradiation was performed under the diagnosis of seminoma of stage I. Here we report a case of seminoma developed in abdominal cryptorchid testis.

Rhabdomyosarcoma is the most frequent cancer involving the trigone of the bladder, the proximal urethra, vagina and paratesticular tissue in children, and 15 percent of rhabdomyosarcoma in children arise in the urogenital tract. Rhabdomyosarcoma is highly malignant neoplasm with a tendency toward early infiltration of adjacent structures and metastases to regional lymphnodes and distant organs. We report tow cases of paratesticular rhabdomyosarcoma with brief review of literatures.

PURPOSE: Authors reviewed CT and MR findings of patients with parapharyngeal masses, and their incidence and characteristic findings were studied. MATERIALS AND METHODS: We reviewed 27 CT and 9 MR of pathologically proven 29 patients with primary parapharyngeal mass Neurogenic tumor (17 cases) and other rare masses (3 carotid body tumors, 2 pleomorphic adenomas, 2 cavernous hemangiomas, 1 cavernous lymphangioma, 2 carotid artery pseudoaneurysms, 1 non-Hodgkin's lymphoma, 1 idiopathic cervical fibrosis) were included and the characteristic CT and MR findings were studied. RESULTS: Neurilemmoma was seen as a well-demarcated, solid mass of heterogeneous attenuation or intensity, so that pleomorphic adenoma of minor salivary gland origin could not be differentiated by demarcation, attenuation, or signal intensity of the tumor itself. The direction of carotid artery displacement was not constant in cases of neurilemmomas while the styloid process was constantly displaced laterally in all cases. Characteristic CT and MR findings of other rare tumors were described. CONCLUSION: Neurogenic tumor is the most common parapharyngeal space mass and the direction of displacement of styloid process might be helpful in differential diagnosis from pleomorphic adenoma. Other rare tumors showed very characteristic CT and MR finidings and could be differentiated easily.
