PURPOSE: Delirium in the elderly is common in the postoperative period but there are only few reports on detailed studies of this condition. Number of urologic patients with postoperative delirium was increas ed in our hospital for recent 24 months. The clinical characteristics of patients with postoperative delirium was analyzed retrospectively. MATERIALS AND METHODS: We selected the patients with postoperative delirium from 1010 patients who had undergone urological surgery under general or spinal anesthesia in the period from Jan. 1997 to Dec. 1999. Diagnosis of postoperative delirium was established with Diagnostic and Statistical Manual of Mental Disorders(DAM-III-R) by psychiatric clinicians. Onset and recovery of symptoms, risk factors, previous psychiatric clinicians. Onset and recovery of symptoms, risk factors, previous psychiatric disorder, relationship with anesthesia, drugs, and surgical procedures, concomittant medical conditions, and complications were retrospectively reviewed. RESULTS: Postoperative delirium was observed in 13 patients (1.3%). All patients were male and mean age was 70.4 years (46-86 years). Surgical procedures included TURP(8 patients), cystectomy (3 patients), nephroureterectomy (1 patient), and bladder rupture repair (1 patient). Delirium became apparent between one day and two days after the operation (mean 32.2 hours) and lasted for up to 7 days (mean 53 hours). Several factors such as older age (>65 years), male patient, longterm medication, past history of CVA, memory impairment, hearing difficulty, traumatic brain contusion, and obsessive personality were thought to be risk factors of postoperative delirium. Treatment with Haloperidol(R) intramuscular injection (2.5-5mg, every 30 minutes, 2-4 times until symptom resolution was achieved) with or without Ativan(R) intravenous injection (2mg) were effective. Complete symptom recovery was seen in 92.3% (12/13) of patients. One patient (7.7%) with previous history of dementia had persistent memory disturbance and disorientation during follow-up periods. CONCLUSIONS: Generally, postoperative delirium is an acute transient confusional state without considerable sequeles. Treatment is sedation and prevention of inadvertent accident associated with confusional state. Urologic surgeon must be attentive to the development of this illness especially when high risk factors were present.

Horizontal Mattress Suture Technique on Microvascular Anastomosis of rat (body weight: 200-250 gm) femoral artery was evaluated. The present study was conducted to compare the horizontal mattress suture with simple interrupted suture on the suture time, patency rate of the sutured vessels, and the histological changes of surgical site of the vessel wall during wound healing period. The mean suture time of the vessel wall with horizontal mattress suture technique was 15 min 49 sec ± 2.14, which is significantly shorter than that of simple interrupted suture technique. The patency rate of the sutured vessel in both groups was statistically not different each other till post-operative 3rd day but patency rate of horizontal mattress suture was higher than that of simple interrupted suture at post-operative 3rd week. The histological findings such as intimal noss, medial degeneration and intimal regeneration were similar in both groups.

Extravasation of toxic chemotherapeutic 'agents cause severe skin ulceration and necrosis which often need secondary surgical intervention. Still, there were not established antidote agent in case of extravasation with mitomycin-c. Dimethyl sulfoxide is known as an effective chemical scavenger of toxic hydroxyl free radical and sodium thiosulfate also was demonstrated significant protector from mitomycin-c induced ulceration by a few experimental studies. Author investigated necrotic area of mitomycin-c injected site and compare to the effectiveness of topical treatment with dimethyl sulfoxide and intradermal injection of sodium thiosulfate according to starting times, forty five mice were divided into 3 groups. Control group(n=5) had no treatment after subcutaneous injection of mitomycin-c. Experimental group I and 11 were 20 mice treated dimethyl sulfoxide and sodium.

A 4-year-old girl developed acute motor, sensory impairment, lower abdominal pain and urinary dysfunction after URI. In acute stage of disease, MRI showed diffuse spinal cord swelling and high signal intensity on T2WI below T2 body level. The patient did not improved and one month later, follow-up MRI showed diffuse spinal cord atrophy and syrinx formation as sequelae of ATM on T1WI below T9 level. To our knowledge, this is the first case showing the sequelae of acute transverse myelitis seen in Korea.

Metanephric adenoma is a rare renal epithelial tumor. Its light microscopic features are very characteristic, and immunohistochemical and electron microscopic studies are not critical to the diagnosis. The literature indicate that, to date, the tumor has behaved in a benign fashion, and predominantly but not exclusively occurred in middle-aged women. It occurs in a wide range up to 11 cm and is usually an incidental finding but may be symptomatic with hematuria or flank pain. Recently, we have experienced a case of renal tumor showing distinctive adenomatous features, which is incidentally found in a 52-year-old female. This tumor is confined to the renal cortex and is well-circumscribed with a characteristic uniform and orderly proliferation of compact well-differentiated small tubules lined by bland oval cells with a very low level of mitotic activity. The term metanephric adenoma is appropriate for this tumor because it accurately describes its bland proliferation of tubules and reflects the embryonic architectural and cytological appearance of this proliferation. The pattern of the tumor, with its occasional papillary glomeruloid- like bodies and foci of elongated tubules, is reminiscent of the fetal metanephric kidney.

Augumentation rhinoplasty using autogenous cranial bone graft (outer table) can be used more successfully than other methods. In patients with congenital or posttraumatic severe saddle nose deformity and lateral deviation, cranial bone graft is an excellent method of augumentation. The advantages of cranial bone graft compared with traditional method of bone graft are summarized as follows; 1. Easy to reach donor site 2. Abundance of material 3. Little pain and functional disability 4. Shorter hospitalization period 5. Inconspicuous donor scar 6. No secondary deformity of donor site 7.Appropriate curvature can be obtained by proper selection of donor site. With the above advantages, we conclude that augumentation rhinoplasty using split cranial bone graft is a good method in correction of congenital or posttraumatic deformity of nose.
