The rim sign in renovascular compromise may be defined as a thin nephrographic rim outlinning a kidney with another wise faint nephrogram. Renal infarction with gelform and blood clots was induced experimentally in 5 dogsand high dose IVP and CT were performed to evaluate renal cortical rim sign after renal infarction. One expireddue to anesthetic technical failure, and one was embolized partially. So we could be obtain the result on 3 dogs.The reults were as follows; 1. The high dose IVP films show cortical rim sign on 24 hrs and 72 hrs films in twodogs. The CT films show rim sign in 3 dogs. 2. The rim sign may be visualized, if the renal artery is occuludedenough to drop perfusion presssure below the authoregulatory range. 3. The high dose IVP and early nephrogramphase are necessary for the rim sign.

In 200 patients with renal stone and upper and midureter stone, we have tried 241 sessions of percutaneous nephrolithotripsy. The success rate of nephrolithotripsy for different location and type was as follows. For renal pelvis stone 96.5%, staghorn stone lOO%, calyceal stone 84.4%, UPJ and upper ureter stone 76.8%, midureter stone 66.7%. We were successful in most of cases after preliminary report of earlier experience with 50 cases. And improvement of the result in removal of calyceal stone and upper ureter stone was especially conspicuous. In addition, we have complied experience with percutaneous removal of stone in patient with solitary kidney and of staghorn stone, and the result was satisfactory. Based on the accumulated experience, it was possible to remove almost all renal stones and most of upper and midureter stones by percutaneous approach although residual stones were present in large pelvis stone and staghorn stone. Thus in future, even when ESWL is widely utilized, endourologic management must be included in the algorithm of treatment of stone diseases to expect better success rate and less complications.

We treated 160 patients with ureteral stones using extracorporeal shock wave lithotripsy (Siemens Lithostar, Germany) and evaluated many factors which influence the results of ESWL such as stone size, location, degree of ureteral obstruction. duration of impaction and adjuvant procedure. Our results showed that. in case of large stones (more than 1 cm in diameter), mid-ureteral stones, long-standing impacted stones or in-situ treatment, the success rates of ESWL were relatively poor. Therefore in cases accompanying the above-mentioned factors, in is necestary to recognize that the patients may be required to repeat ESWL. The results also suggest that the use of an ureteral catheter or stent may contribute to a slightly higher success rate. But we prefer in-situ extracorporeal shock wave lithotripsy to an ureteral stent because it is an invasive procedure.

It has been recognized for many years that a proportion of patients with bladder cancer have their tumors caused by past exposure at work to carcinogenic aromatic amines. All patients attending the Department of Urology Yonsei University Hospital with bladder cancer during the period from August, 1981 to July, 1983 are routinely interviewed and full occupational histories are taken. One use of the histories collected has been to identify patients with occupational tumors. This study has designed to provide information regarding the value of cytologic examination of urinary tract specimen in the early detection and mass screening in cases of bladder cancer. Two hundred fifty two patients were subjected to this study. These patients have taken cytologic examinations at the Department of Urology, Yonsei University Hospital during the same period. The series compromised 156 consecutive cases without clinically or histologically verified bladder cancer and 96 consecutive cases of histologically verified transitional cell neoplasms of the bladder. Following results were obtained according to the various analyses. 1) There were 75 positive tests from patients with proved cancer(78.1%). 13 false positive cytological diagnoses malignancy were made in the 156 patients without bladder cancer(8.3%). It showed that cytological study is useful in the early detection and mass screening of bladder cancer. 2) The diagnostic accuracy of urinary cytology appears to be related to the quality of cytological preparations and the histological grade of bladder cancer. The frequency of positive findings in cases of grade II(79.6%) was much higher than that of grade I (42.9%). 3) 10.4% of patients gave their histories which suggested relevant occupations with possible exposure to carcinogen.

Malignant melanoma of female urethra and vulva is extremely rare and the prognosis remains poor inspite of several types of treatment. We experienced a case of malignant melanoma on urethra and vulva, which was managed by radical cystectomy and vulvectomy with bilateral groin lymphnode dissection. Adjuvant therapy for metastasis following lymphnode dissection with Interferon was done.
