Simulated three-dimensional (3D) imaging represents reformation of conventional sectional imaging data into a series of images that closely resemble the original studied structure. We tried to make 3D mucosal surface images of the sinonasal cavities, pharynx and larynx, and evaluated the feature of normal anatomy in 28 subjects. In the sinonasal cavities, 3D imaging was capable of demonstrating the inner wall of paranasal sinuses and its openings, and general status status of the nasal cavity. In the nasal cavity. In the nasopharynx, 3D imaging provided an easy concept of sectional images as 3D picture and displayed anatomic subsites and lesions comparable to that in fiberscope. In addition, 3D imaging had advantages in overcoming the technical limitations in fiberscope. In the larynx and hypopharynx, 3D imaging gave a 3D concept of the laryngeal structures and presented additive information not seen in axial iamges thus enabling access to regions beyond the scope of fiberscope. In conclusion, 3D imaging allows an easy conceptualization of transaxial CT images in complex anatomic areas and provides additional in formations undetectable in transaxial CT. We believe that the spaces of the sinonasal cavities, pharynx and larynx would be a new field of application of 3D image.

Obstruction on the urinary tract eventually results in damage to the kidneys and loss of function. The questions that concern the clinician are the degree of nephron loss in that kidney and the potential for recovery following the relief of obstruction. 99mTc DMSA accumulates in tubule cells and has been proposed as a marker of the tubular mass. The authors estimated the renal uptake ratio of 99mTc DMSA for the degree of nephron loss corresponding to duration of hydronephrosis following left ureteral ligation in 5 NewZealand white rabbits and the potential for recovery following percutaneous nephrostomy of hydronephrosis in 24 rabbits. While the renal uptake ratio of 99mTc DMSA of the kidney with unilateral hydronephrosis following ureteral ligation reduced dramatically within 24 hour, that of the opposite healthy kidney increased, and the total renal uptake ratio was same as normal functioning kidneys before ureteral ligation. Upon ureteral release, there was no evidence of definite recovery or impairment in the experimental kidneys for 5 days. The authors conclude that a combination of ureteral release and administration of some drugs such as renal vasodilator or diuretics is an appropriate treatment for the recovery of function in unilateral hydronephrosis.

BACKGROUND: This study was performed to evaluate our experience on laparoscopic appendectomy. METHODS: Retrospective analysis was performed on 2,856 patients who had been operated by laparoscopic appendectomy under diagnosis of acute appendicitis at the Sung-Ae Hospital and Kwang-Myoung Sung-Ae Hospital from October 1991 to July 1998. RESULTS: Among 2,856 patients who had undergone laparoscopic appendectomy,2,379 patients (83.3%) were operated due to simple acute appendicitis, 275 patients (9.6%) due to perforated appendicitis. Operation time was 44.6 minutes for simple acute appendicitis and 60.3 minutes for perforated appendicitis. In perforated appendicitis, intra-peritoneal irrigation and drain insertion was performed. The length of hospital stay in patient with simple acute appendicitis was 3.7 days (5.82 days in conventional appendectomy) and patients with perfotrated appendicitis was 6.1 days (9.91 days in conventional appen-dectomy). Complications such as wound infection, intra-abdomen abscess, trocar site bleeding, subcutaneous emphysema developed in 43 (1.5%) patients (79/1,947, 4.5% in conventional appendectomy). In 202 (7.1%) patients, appendix was normal, but another diseases were detected, including acute pelvic inflammation, ovarian cyst, mesenteric lymphadenitis, enteritis, diverticulitis in order. CONCLUSION: Overall complication rate was lower in laparoscopic appendectomy compared with conventional appendectomy and the length of hospitalization of laparoscopic appendectomy was shorter. When the acute appendicitis is suspected, especially in the reproductive women, the laparoscopic approach would be better diagnostic and therapeutic value than conventional method. Therefore laparoscopic appendectomy would be replaced with conventional appendectomy.
