1.Anatrophic nephrolithotomy: experience in 55 cases.
Yeungnam University Journal of Medicine 1992;9(1):149-155
55 consecutive anatrophic nephrolithotomies on 53 patients performed between July, 1983 and June, 1990 were reviewed. The patients (36 male and 19 female) ranged in age from 3 to 72 years. The operation time averaged 219.8 minutes with a range of 120-330 minutes, and the ischemic time ranged between 20 and 90 minutes, with a mean of 43.5 minutes. Postoperative complications developed in 18 patients, which were such as persistent urinary tract infection in 5cases (9.4%), atelectasis in 4 (7.5%), transient urine leak in 2 (3.8%), delayed bleeding in 2 (3.8%) and urinary retention in 2 (3.8%). Postoperative residual stones were identified in 15 (27.3%), but in 8 of these 15patients stones were delivered spontaneously and thus 48 of 55 cases (87.3%) became stone free. The recurrence of stone was noted in 2 out of 48 patients during the short follow up period. Anatrophic nephrolithotomy seems to be an effective method compared to other procedure because of decreasing recurrence of stone by complete stone removal and reconstruction of abnormal collecting system.

Male urethral diverticulum is uncommon lesion, furthermore calculus formation within the male urethral diverticulum is very rare. Generally, urethral diverticula are classified as congenital and acquired. The majority of male urethral diverticula are acquired and approximately 10 to 20 per cent are congenital. Acquired urethral diverticula in the male may arise from many sources, including infection (prostatic abscess, infection of periurethral glands, hematoma or schistosomiasis), obstruction (stricture, impacted stone, Cunningham clamp or condom catheter) and trauma (instrumentation, external injury and pelvic fracture). Calculi formation is more common in the acquired diverticulum owing to stagnation of urine and infection. These calculi in the diverticulum usually are solitary and may attain considerable size with predisposing factors, 1) a ureteral or bladder calculus that is lodged in the urethra 2) urethral trauma or stricture, 3) calcification around a foreign body or hair. The treatment of urethral diverticulum combined with stone is excision of the diverticula with removal of stone. We treated two cases of urethral diverticulum combined with stone in the male, and report with review of literature.

Vasectomy has become a popular method for male sterilization in Korea and this, in turn, has been followed by an increase in the number of patients requesting vasectomy reversal. Recently, many authors have reported a high success rate of vasovasostomy using microsurgical techniques. However, a significant discrepancy persist between the patency and pregnancy rate despite improvements in surgical techniques. A total of 200 patients undergoing vasovasostomy from May 1983 to April 1990 were reviewed. Of these 200 patients, only 130 patients (98 patients by two-layer, 32 patients by modified two-layer technique) could be followed up and analyzed as to pregnancy rate related to age, vasal obstructive interval, gross appearance and sperm quality of the vas fluid, operative method, and presence or absence of sperm granuloma. Success rates were 90.3% for patency and 65.4% for pregnancy. With regard to factors influencing to operation, it seemed that the results were better when there was a shorter vasal obstructive interval, watery vas fluid, presence of normal morphologic sperm quality, presence of sperm granuloma, and when the operation was done using the two-layer technique. However, no statistically significant difference was found, except between the bilateral presence and absence of sperm granuloma at the vasectomy site. Thus it is suggested that the most important single factor influencing the success rate of vasovasostomy is a meticulous and skillful operative technique itself, althought other factors may affect the outcome. More effort and research are needed to find the factors affecting the success rate of vasovasostomy.

Management of the small lower ureteral stone has been attempted by either transurethral manipulation or expectant therapy. To date, however, the choice of proper method has depended mostly on clinician's preference, and the effectiveness of the transurethral stone manipulation has remained controversial. Herein we evaluated the effectiveness of the transurethral stone manipulation, using with the Dormia dislodger, in 37 patients with lower ureteral stone less than 10mm in greatest diameter. The results are summarized as follows. 1. The overall success rate was 68% (25 of 37 patients); Immediate delivery of the stone was observed in 16 of 37 patients. In another 5 patients the stone was removed at the time when the indwelled ureteral catheter was taken out. In the remaining 4 patients the stone passed spontaneously within a week following the procedure. 2. Higher success rate was observed in smaller stone; 79% in less than 4 mm, 58% in 46 mm, and 33% in 610 mm in it's greatest diameter, respectively. 3. The morbidity rate was 8.1% (3 of 37 patients); In one patient a broken basket was retained in the ureter, which was removed at the time of ureterolithotomy. In another patient a ureteral stricture requiring periodic dilation was complicated. And in the other patient persistent hematuria was observed, which was relieved by conservative management. These results suggest that transurethral manipulation might have to be initially applied to unremittingly painful patients with small lower ureteral stone.

Giant lymph node hyperplasia (Castleman's disease) is a rare disease, which represents a peculiar form of lymph node hyperplasia. Generally, it has been considered as benign and localized disease but recently, revealed malignant transformation in some cases of multicentric form. It usually occurs on the mediastinum and occasionally neck, lung, axilla, mesentery, broad ligament, retroperitoneum or soft tissue of extremities. Histopathologically, it is divided into hyaline vascular or plasma cell type and the former is characterized with prominent vascular proliferation and hyalinization in the central portion and tight concentric layering of lymphocytes at the periphery of the follicles (mantle zone) and the latter is characterized by a diffuse plasma cell proliferation in the interfollicular area. From the point of view of clinical presentation, it has been divided into solitary form, which presents as a localized mass located most commonly in the mediastinum, and multicentric form, which occurs multiple location and has systemic manifestation and transformation into malignancy. Herein we report a case of Giant lymph node hyperplasia occurring in the left spermatic cord in a 58-year old male with brief review of literatures.

9.A Case of Renal Multilocular Cyst.
Korean Journal of Urology 1988;29(6):1010-1014
Multilocular renal cyst having an entity of uncertain nature, is an uncommon benign lesion. As a treatment modality of renal multilocular cyst, simple or radical nephrectomy has been performed because of the difficulty in its accurate diagnosis and the documented association with malignancy. Herein, we report a case of renal multilocular cyst which was successfully treated by extirpation of the cystic mass only with preservation of the remaining normal renal parenchyma.

Postischemic functional impairment of the kidney is a severe problem following living or cadeveric renal transplantation. It is well established that a substantial component of postischemic injury is caused by oxygen free radicals generated from xanthine oxidase at ischemia/reperfusion (VR) through lipid peroxidation. Glutathione is well known as a radical scavenger of oxygen free radicals. Malonyldialdehyde (MDA) is a stable end product of lipid peroxidation. The present study was undertaken to investigate whether the measurement of levels of xanthine oxidase activity, glutathione, and MDA in renal tissue could be used as indicators of renal function following I/R injury 50 male Sprague-Dawley were divided into 3 groups; control group (N=10), allopurinol-pretreatment group (Group A, N=20) and no-pretreatment group (Group B, N=20) for in-vitro and in-vivo study. Animals in in-vitro study underwent bilateral renal ischemia for 60 min after pretreatment with allopurinol in group A and saline in group B, and left nephrectomy was then performed for study of ischemic injury. After 30 min of right renal reperfusion, right nephrectomy was then performed for VR injury study. Xanthine oxidase activity, glutathione, and MDA were measured in nephrectomized kidney tissues. In-vivo renal function studies were performed in both group A and B with measurement of creatinine clearance (Ccr) at 7th day of experiments after renal ischemia for 60 min. The xanthine oxidase activity decreased significantly in group A, but increased significantly in group B. The type conversion ratio increased significantly in group B. Glutathione levels decreased significantly in group B compared to group A. MDA levels increased significantly in group B compared to group A. Ccr decreased significantly in group B compared to group A. Thus, it is suggested that the measurement of levels of xanthine oxidase activity, glutathione, and MDA in renal tissue following ischemia/reperfusion injury could be used as indicators of renal function.
