A 4 day old male neonate with severe dehydration, uremia, and hyperbilirubinemia presented with bilateral renal vein thrombosis. Following exchange transfusion and peritoneal dialysis renal function returned to normal without nephrectomy. The importance of adequate and prompt management of renal failure to expect the spontaneous recanalization is stressed. Because of the high mortality rate associated with the nephrectomy in neonates, adequate and prompt medical management including peritoneal dialysis or exchange transfusion, if indicated, with expectation of spontaneous recovery is considered the treatment of choice in this age group.

Intraoperative pulmonary thromboembolism (PTE) is rare, but is nevertheless one of the important causes of morbidity and mortality in patient undergoing surgery. However, The detection of PTE is difficult because it's clinical symptoms and signs are nonspecific during surgery, and specialized diagnostic tools are not readily available in the operating room. We report a case of PTE due to cancer emboli with thrombi encountered during a nephrectomy in patient with renal cell cancer, and demonstrate that one-lung ventilation can aid in the diagnosis of massive PTE when the evaluation is suspected.

The morbidity and mortality rates are believed to be much higher if the staghorn calculus is left unoperated, since complications resulting from infection and/or obstruction may become life-threating. So, surgical removal is essential element in the successful management of the majority of patients with staghorn calculous disease. To understand better the optimal management, we did a retrospective analysis of 41 patients treated during 12 year periods. Surgical managements were performed in 36 patients (41 kidneys) and no operation in 5. Methods of surgical managements were extended pyelolithotomy in 11 cases, extended pyelolithotomy and pyeloplasty in 1, extended pyelolithotomy with parenchymal extension in 4, ex- tended pyelolithotomy with parenchymal extension and partial nephrectomy in 1, anatrophic nephrolithotomy in 7, antrophic nephrolithotomy with partial nephrectomy in 3, partial nephrectomy in 3, partial nephrectomy in 3 and nephrectomy in 9. Complete removals of calculi were done in 32 kidneys(69.6%). Clinical complications occurred in 14 kidneys(30.4%) ; 5 were remnant stones(10.8%), massive bleeding in 2, renal artery injury in 1, urine leakage in 3, pneumothorax in 2 and hematuria and sepsis in 1. The managements of complications were reoperation in 8 cases, conservative treatment in 5 and no follow up in 1.

This Study was designed to characterize the unfavorable prognostic factors of renal cell carcinoma through reviewing 27 cases with radical nephrectomy during the past 10 years from 1976 through 1986. The presence or absence of tumor invasion into renal capsule, perinephric fat, renal vein, regional lymph node, pelvis and/or ureter, hematuria at the time of first examination and the difference in the size of tumor and tumor cell type were studied. The 100 person-year mortality rates were analyzed with the chosen prognostic variables. Tests of significance between the difference in mortality rates of each two groups with or without a given characteristics were performed with Z-test. Author results as follows. : 1. The survival rate was decreased independently by the unfavorable factors such as the presence of tumor invasion into renal vein, regional lymph node, pelvis and/or ureter and tumor cell type other than clear cell(P<0.001, <0.001, <0.001, <0.05 respectively). 2. The survival rate was not affected by the following factors such as the presence or absence of hematuria at the time of first examination, tumor invasion into renal capsule, perinephric fat and the difference in size of tumor.

We reviewed 113 patients of renal trauma between May, 1989 and May, 1995 to clarify the characteristics of the patients who need surgical management. Of the 113 renal trauma patients, 80 were treated conservatively and remaining 33 were treated with surgically. The causes of injury were blunt trauma in 112 and penetrating injury with gunshot in 1. The grade of injury was contusion in 48 (42.5%), simple laceration in 25 (22.1 %), deep laceration into collecting system in 26 (23.0%), shattered kidney in 7 (6.2%), and pedicle injuries in 7 (6.2%). Aside from 1 case of grade 2 Wilms' tumor patient, all the surgically treated patients were over grade 3. Surgically treated patients had more associated trauma, especially in nephrectomy cases. Shock is the characteristic feature of surgically treated patients' symptom. All the 33 case of exploration was done without preliminary vascular pedicle control prior to opening the Gerota's fascia. Nephrectomy was done in 15 cases, and partial nephrectomy or renorrhaphy was done in 18 cases. Comparing the two groups, the former showed more shock rate (53.3 vs.33.3%), combined organ injuries (2.05 vs 1.32), and death rate (6.67 vs. 0%) (P<0.05). Gender ratio, patients' age and transfusion amount (2,984 vs 3,204ml.) did not show difference in both groups. The latter group took more time (98 vs. 128 min.) during operation. The causes of nephrectomy were renal pedicle injuries in 5 cases, shattered kidney in 7 cases and Grade III/V renal injuries with underlying anomalies in 2 cases (polycystic degeneration in one and hydronephrosis in the other case). One case was traumatic rupture of Wilms' tumor. In the management of traumatic renal injuries, patients who have more severe and associated organ injury, especially in the nephrectomy group, received surgical treatment. Shock is the only characteristic sign of surgical treatment group.

A clinical evaluation was made with particular attention to surgical management on patients with staghorn calculi who had been admitted to the Department of Urology, Kyungpook National University Hospital during 10 years periods from January, 1975 to December, 1984. The results were as follows: 1. Out of total 2,634 in-patients, 469 were due to urinary stones and 51 due to staghorn calculi. 51 patients with staghorn calculi were 2% of total admission and 11% of patients with urinary stones. 2. The calculus was unilateral in 50 patients (right in 25 and left in 25) and bilateral in 1. Of 5O unilateral staghorn calculi l was in left solitary kidney. 3. 49 patients had presenting symptomatology and 2 patients had no symptoms. The most common symptom was flank Rain(80.4 %). 4. Excretory urogram showed marked hydronephrosis in 8 cases, mild to moderate hydronephrosis in 3O normal collecting system in 3 and non-visualized kidney in 10. 5. Urine cultures yielded organism in 19 of 41 cases: E. coli, Klebsiella and Staphylococci in 4 respectively and Enterobacter in 3. 6. The treatment modality was surgical intervention .in 47 patients (48 operations) and conservative management in 4. 4S surgical interventions were nephrectomy in 10 and conservative treatment 38. Conservative surgery was extended pyelolithotomy in 12, extended pyelolithotomy with parenchymal extension in 11, anatrophic nephrolithotomy in 9, partial nephrectomy in 5, and extended pyelolithotomy with ureterocalicostomy in 1. 7. Except 6 cases with remnant calculi, no mortality and significant morbidity was found in 38 cases with staghorn calculi treated by conservative surgery.

PURPOSE: A retroperitoneoscopic adrenalectomy is theoretically the ideal procedure for an adrenalectomy. However, it is not popular due to its technical difficulty. Herein, we report our experience with retroperitoneoscopic adrenalectomies and describe the difficulties encountered during the operations. METHODS: From November 1996 to October 1999, a total of 41 retroperitoneoscopic adrenalectomies were performed. Forty (40) patients had a unilateral adrenal tumor (size: 1-6 cm): 21 aldosteronomas, 12 Cushing adenomas, 3 neurogenic tumors, 2 nonfunctioning adenomas, 1 vascular cyst, and 1 angiomyolipoma of the kidney. One (1) had bilateral hyperplasia. The operations were carried out in prone position in all cases with 3 trochars. RESULTS: Thirty five (35) operations were completed endoscopically. Five were converted to open procedures, and one was converted to a transperitoneal laparoscopic approach. The causes of conversion were 1 severe subcutaneous emphysema, 2 technical difficulties, 1 bleeding, 1 partial nephrectomy, and 1 missing tumor. The average operating time for the complete endoscopic adrenalectomies was 183 minutes in the first 14 cases and 142 minutes in the next 21 cases. There was no operative morbidity or mortality. The average hospital stay was 4.3 days in the first 14 cases and 2.8 days in the next 21cases. CONCLUSION: A retroperitoneoscopic adrenalectomy is a less invasive procedure than any other adrenalectomy procedure, and its only disadvantage is technical difficulty. However, the technical difficulty can be overcome with increasing experience.
