ABSTRACT: 28-year-old female received dialysis treatment due to chronic renal failure caused by polycystic kidney disease. Later, she underwent a laparoscopic splenectomy and ABO incompatible living kidney transplantation successfully following bilateral renal contraction therapy with renal transcatheter arterial embolization (renal TAE). A unilateral or bilateral native nephrectomy of a massively enlarged kidney performed at the time of renal transplantation is a common treatment in polycystic kidney patients scheduled for transplantation. On the other hand, when treated with renal TAE, such patients can avoid a laparotomy, which provides several advantages when undergoing peritoneal dialysis in the future or a laparoscopic splenectomy prior to ABO incompatible kidney transplantation. Furthermore, we consider that bilateral renal TAE is necessary for polycystic kidney patients prior to renal transplantation for a variety of reasons, including problems associated with contrast nephropathy if renal TAE for left kidney is remained after renal transplantation.

ABSTRACT: A 21-year-old man with bilateral hypoplastic kidneys underwent laparoscopic splenectomy and ABO-incompatible living renal transplantation. After the splenectomy, pancreatic leak occurred and it caused intra-abdominal bleeding on the 10th and 16th postoperative day, so emergency operations were performed. Then the graft function had become stable and he was discharged on the 75th postoperative day. Although intra-abdominal bleeding due to pancreatic leak often causes a fatal condition, he was successfully treated by suppression of pancreatic external secretion using octreotide and appropriate drainage.

ABSTRACT: We report a case of renal cell carcinoma in which interferon-a therapy was effective in reducing the tumor thrombus extending into the inferior vena cava. A 66-year-old man was referred to our hospital with a complaint of macroscopic hematuria, cough and general fatigue. We made a diagnosis of a left renal cell carcinoma with tumor thrombus by imaging examination. Because his performance status was 3, a radical operation was considered risky. Twenty-two months after the start of interferon-a therapy, the tumor thrombus was markedly reduced in size, and the clinical response was evaluated as partial response by the response criteria for urological cancer treatrment. Because of improvement of the performance status and downsizing of tumor thrombus, we performed radical nephrectomy. Pathological examinations revealed that viable renal cell carcinomas were found in the primary lesion and the tumor thrombus. In some cases, interferon-alpha therapy is useful and safe in the treatment of the tumor thrombus. Furthermore, radical nephrectomy and complete resection of the tumor thrombus prolongs postoperative survival.

ABSTRACT: A 26-year-old man presented with a swelling of the right scrotal content, lumbago and exertional dyspnea. He underwent high inguinal orchiectomy. Histopathological examination of the specimen revealed yolk sac tumor and mature teratoma. Further evaluation revealed mediastinal and retroperitoneal lymph node metastases (stage IIIA). A single course of BEP (bleomysin, etoposide and cisplatin), two courses of chemotherapy consisting of nedaplatin and irinotecan, and three courses of TIP (paclitaxel, ifosfamide and cisplatin) were delivered. The previous abnormally elevated serum biomarkers (AFP, beta-hCG and LDH) returned to normal levels, but the mediastinal and retroperitoneal masses continued to enlarge slowly. The CT-guided biopsy of the mediastinal mass was performed, and histologic study revealed no evidence of malignancy. He underwent excision of the mediastinal masses and retroperitoneal lymph node dissection. Histologic examination of the resected specimens revealed mature teratoma without malignant components. These results were compatible with growing teratoma syndrome. 30 months after the first excision of mediastinal mass, he underwent the second excision of recurrent mediastinal mass in the absence of biomarker elevation. The resected specimens revealed mature teratoma without malignant components. He is alive for 49 months after high inguinal orchiectomy and free of carcinoma.

ABSTRACT: A 46-year-old man had undergone radical high orchiectomy because of a tumor of the right spermatic cord. Pathological diagnosis was atypical lipomatous tumor. Six years later, he had asymptomatic swelling in his right groin. Local recurrence was suspected, and surgical resection of the tumor with a sufficient surgical margin was performed. Pathological diagnosis was well-differentiated liposarcoma, sclerosing type. Ten cases of recurrent spermatic cord liposarcoma, including the present case, have been reported in Japan. Because of the possibility of local recurrence, spermatic cord liposarcoma needs strict and long-term follow up.

ABSTRACT: We report the diagnosis and treatment for carcinoma in situ of the bilateral upper urinary tracts after total cystectomy and ileal conduit by intentionally inducing hydronephrosis. A 75-year-old man whose chief complaints were macroscopic hematuria and bladder irritabilities was diagnosed carcinoma in situ of the bladder and underwent total cystectomy and ileal conduit. 26 months after the operation, the cytological examination of ileal conduit urine revealed urothelial carcinoma. Since the radiographic findings in the upper urinary tracts and ileal conduit were negative, we constructed bilateral percutaneous nephrostomies by intentionally inducing hydronephrosis. Since two serial cytological examinations of the urine sampling from the bilateral pyeloureteral systems revealed urothelial carcinoma, we performed the percutaneous Bacillus Calmatte-Guerin perfusion of the bilateral upper urinary tracts. The therapy was repeated at weekly intervals for a total of 11 perfusions and the cytological examination of ileal conduit urine became negative 4 months after the beginning of the therapy. Intentionally induced hydronephrosis is useful for the diagnosis and treatment for carcinoma in situ of the bilateral upper urinary tracts after total cystectomy and ileal conduit.

ABSTRACT: We present a 60-year-old female who underwent living unrelated renal transplantation from her 62-year-old husband. The primary immunosuppression consisted of tacrolimus, mycophenolate mofetil and steroid. We did not recognize any rejection in a histopathological study. The total ischemic time to carry out anastomosis of the two renal arteries was 121 minutes. After hemodialysis 5 times for acute tubular necrosis, her renal function improved. She was discharged on the 33rd postoperative day when her serum cretinine level was 1.0 mg/dl. The graft function was stable at 6 months after transplantation. We discussed living unrelated renal transplantation in the elderly population in Japan.

ABSTRACT: A 39-year-old man whose chief complaints were general fatigue and bloody phlegm was diagnosed with testicular cancer and underwent left high orchiectomy at an affiliated hospital. The histopathologic diagnosis was chorio carcinoma. Several imaging examinations revealed the metastases in the lung, liver, brain, stomach, kidneys and skin. In spite of various chemotherapies, he died 17 months after the operation. Skin metastasis of testicular cancer is very rare and this is the twelfth case reported in the world, to our knowledge. The significance of skin metastasis in testicular cancer is discussed.

ABSTRACT: Two cases of ureteral polyp resected by a transurethral approach are presented. Case 1: A 70-year-old woman was referred to our clinic because of hydronephrosis incidentally found. Excretory urography demonstrated a filling defect with a long and round smooth contour in the left lower ureter without hydroureter. Urine cytology was negative for malignant cells. Under the clinical diagnosis of left ureteral polyp, polyp was resected transurethrally. The pathological diagnosis was fibroepithelial polyp. Case 2: A 59-year-old woman was referred to our clinic with a chief complaint of macroscopic hematuria. Excretory urography revealed a filling defect with a long and round smooth contour in the left upper ureter. Because urine cytology was negative for malignant cells, left ureteral polyp was suspected. After the operation by tranthurethral approach, the pathological diagnosis was fibroepithelial polyp. No intraoperative complication was observed in either case. Ureteral polyps resected by a transurethral approach are relatively rare. We reviewed and discussed 46 cases of ureteral polyp resected transurethrally, reported in Japan including our two cases.
