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.

A full understanding of the potential anatomical variations of the renal veins and its branches is imperative for donor nephrectomies. Preoperative renal angiography is the most important study to evaluate renal vascular anatomy. By this technique. the renal arteries are well visualized. but it is almost impossible to obtain the exact informations of the renal veins and its branches. To prevent extensive manipulation of the kidney by profuse bleeding. the exact information of the renal veins and its branches is very important. Based on intraoperative observation of 240 consecutive cases of donor nephrectomies. we observett. the common renal vein variants. Left renal veins usually had two branches; adrenal vein proximally and gonadal vein distally. Lumbar veins were identified in 112 cases(56.7%) Lumbar veins were connected to renal veins posteriorly near the draining site of gonadal veins. Therefore it is very important to dissect very carefully the posterior part of renal vein around the insertion of gonadal vein because of the existence of lumbar vein which might cause troublsome bleeding by accidental tearing. Especially when the cases of angulated renal veins were observed by renal angiography. the more attention will be required due to the strong possibility or the existence of lumbar vein.

We review 66 patients with lower caliceal stones treated with extracorporeal shock wave lithotipsy. One of the major problems involved with extracorporeal shock wave lithotripsy is the high rate of residual stone fragments in the lower calices. We observed the influence of the presence of lower caliceal dilatation, hydronephrosis, and the size of alone on the passage of stone. Thirty-nine of the 66 patients with a lower caliceal stone and no stone fragments. The success rate was only 59 per cent. The stone was completely fragmented in 59 of 66 (89%) patients. Thirty-nine of 59 patients who had completely fragmented stones. had no residual fragments. The patients who had no lower caliceal dilatation and a relativgly small size stone (less than 1.5 x 1.0 cm). such as in group 4. had a high success rate of 70%. The patients with a large stone or the presence of caliceal dilatation. were expected to low success rate, therefore there was a need for repeated treatment with extracorporeal shock wave lithotripsy and combined treatment with percutaneous nephrostomy.

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.

Actinomycosis, in which the principal causative agent in man is known to Actinomyces israelii, is a chronic, suppurative diseases characterized by extensive fibrosis, multiple abscesses, and formation of sinus tracts that drain suppurative exudates. On the basis of the anatomical sites involved; it can be subclassified into the cervicofacial form, which is the most common form, pulmonary form and abdominal form. Kidneys are rarely affected. Clinically, radiologically, and at operation it is difficult to differentiate the renal actinomycosis from renal tuberculosis and renal carcinoma. The prognosis is excellent after nephrectomy followed by appropriate antibiotic therapy. We presented a case of renal actinomycosis with a brief review of the literatures.
