Primary tumor of the renal pelvis and ureter is relatively rare disease, but usually malignant. It's prognosis is dependent upon the early detection, accurate diagnosis, procedure for treatment, and tumor grade and stage. Therefore, urologist should endeavor after accurate diagnosis and definitive treatment. A clinical observation was done on the 11 patients with renal pelvic tumor and the 3 patients with ureteral tumor at the Department of Urology, Kyungpook National University Hospital during the period of 4 years from January, 1978 to December, 1981. The results were as follows: 1. There were 9 men and 5 women, giving a ratio of 1.8 to 1. The average age at presentation of the 14 patients was 51.4 years. 2. On excretory urogram, nonvisualization of the kidney was the most prevalent sign in 10 patients. Retrograde pyelogram was done in 11 patients in whom findings of IVP were not sufficient for diagnosis. Renal angi0graphy was done in 9 patients. 3. Urine cytology was positive in 2 of 14 patients. 4. Of the 13 patients treated, 12 were proved to have transitional cell carcinoma, and 1 was leiomyoma. In 3 of the 11 patients with renal pelvic tumor, Concomitant ureteral tumor was present at diagnosis. And in 2 of the 11 patients with renal pelvic tumor developed subsequent urothelial tumors in the ureter and/or bladder after simple nephrectomy. 5. Nephroureterectomy including resection of a bladder cuff was done in 11 patients, and in 2 of these was also performed lymphadenectomy. Simple nephrectomy was done in 2 patients with renal pelvic tumor under the misdiagnosis of renaltuberculosis. 6. Postoperative complications developed in 3 cases, wound infection, pneumothorax, and death, in each case.

PURPOSE: To evaluate the effectiveness of intreaepithelial photorefractive keratectomy (IE-PRK) for the treatment of myopic regression after laser in situ keratomileusis (LASIK) METHODS: 38 eyes of 22 patients who had previous LASIK for myopia were selected and retreated with IE-PRK, in which a photoablation was performed directly in the epithelium without damage to Bowman's layer. All eyes were elapsed at least 6 months after the LASIK. Follow-up was up to 6 months and within +/-0.50 of emmetropia on 6 months after surgery was considered as a success. RESULTS: Before IE-PRK, the eyes regressed to a mean of .1.26+/-0.45 D spherical equivalent (SE). The mean SE at 1 week after IE-PRK was .0.44+/-0.88 D, 1 month was .0.59+/-0.45 D, 3 month was .0.63+/-0.41, 6 month was .0.62+/-0.43 (p<0.05). 23 of the 38 eyes (60.5%) had refraction within +/-0.50 and were considered as successfully treated. Preoperative mean best corrected visual acuity (BCVA) was 0.33+/-0.18 (Snellen equivalent) and final mean BCVA was 0.77+/-0.99 (p<0.01). There were no significant complications of corneal flap. CONCLUSIONS: The results of this study indicate that intraepithelial photorefractive keratectomy appears to be a safe means for treating patients for regression after LASIK procedure. But success rate was not so good as the enhancement. Controlled studies with larger population will be necessary to evaluate the accuracy of the method more correctly.

PURPOSE: To compare results of laser in situ keratomileusis (LASIK) and laser epithelial keratomileusis (LASEK) for the treatment of high myopia. METHODS: In this study, 129 patients with a manifest refraction over -6.00 diopters were assigned two groups for 144 eyes of 72 patient treated with LASIK and 114 eyes of 57 patients treated with LASEK. Uncorrected visual acuity, manifest refraction, corneal haze and other complications were reviewed in LASIK- and LASEK-treated eyes at 6 months after the operation. RESULTS: At the 6-month follow-up, there were significant between-eye differences in uncorrected visual acuity and mean spherical equivalent. And LASEK-treated eyes had more corneal opacity and it makes decreased uncorrected visual acuity. CONCLUSIONS: Both laser refractive surgeries were safe and effective methods to treat eyes with high myopia. But LASIK procedure may prove superior to decrease corneal opacity and visual predictability.

In an effort to study the underlying diseases, management and postoperative complications of nephrectomized patients, author analyzed the records of 171 nephrectomized patients who were treated at the Department of Urology, Kyungpook National University Hospital during the past 10 years. The results were as followers: 1. These 171 nephrectomized patients revealed giving rate of 14.9% to the total urologic operations during above periods. 2. The most frequent year distribution was 1981, being 31 patients, followed in frequency by 1980 in 29 and 1979 in 25. Over half of nephrectomized patients were seen since 1979. 3. The most commonly involved age group was the 3rd decade (24.6%), followed in decreasing order of frequency by 6th decade (18.1%) and 4th decade (17.5%). Sex ratio. male to female, was 1.9:1. 4. The most common causative disease was the tumor comprising 43 patients (25.1%) out of 171 nephrectomized patients, followed in order of frequency by renal injury in 40(23.4%), renal tuberculosis in 33(19.3%), renal infection in 21(12.3%) and hydronephrosis in 16(9.4%). 5. The most frequently employed surgical approach of nephrectomy was through translumbar (64.3%), followed by transperitoneal (30.4%), thoracoabdominal (4.7%) and posterior lumbar (0.6%). The translumbar approach was undertaken nearly in all nephrectomized patients except transperitoneal approach in 18 tumor patients, thoracoabdominal in tumor patients and transperitoneal approach in 26 renal injury patients. 6. Postoperative complications were developed in 21 patients and 2 of these were died. 7. One hundred and forty one patients (82.5%) were hospitalized between 8 and 21 days, 24 over 22 days and 6 below 7 days.

PURPOSE: We investigated the adhesion rate and morphologic change of lens epithelial cell (LEC) according to materials of intraocular lens (IOL). With the results, we estimated the appearance and characteristics of posterior capsular opacity after cataract extraction. METHODS: LECs were prepared from fresh bovine lens. Hydrophobic acylic IOLs such as Acrysof(R) and Sensar(R) and hydrophilic acrylic IOLs such as Corneal(R) were tested. On the days 2, 9 and 12 of LEC culture, we calculated the adhesion rate and observed the cellular morphologic changes. Immunostaining with alpha smooth muscle actin (SMA) was performed. RESULTS: Adhesion rate was higher in hydrophilic lens on the days 2 and 9 (p-value=0.029). Acrysof(R) had the lowest adhesion rate. LEC in hydrophobic IOL showed differentiation to myofibroblast that was strong positive for SMA. LEC in hydrophilic IOL preserved natural cellular morphology until the day 12. Immunostaining with SMA was nearly negative. CONCLUSIONS: Hydrophobic acrylate induced much differentiation from LEC into myofibroblast, but had low adhesion rate. Hydrophilic acrylate does not induce the differentiation, but has high adhesion rate.
