A case of renal malignant lymphoma is reported. A 74-year-old man was admitted to our hospital on September 8, 1995, complainning of right flank pain, abdominal mass, and anorexia for two months. Physical examination revealed an enlarged right axillary lymph node and abdominal mass of child's head size. Computerized tomography showed a tumor (11 x 7 cm) encompassing the right kidney parenchym, and enlarged paraaprtoc lymph nodes with invasion of the left iliac creat. Transcutaneous echo-guided needle biopsy revealed that the tumor was non-Hodgkin's malignant lymphoma, diffuse large cell type, positive for B cell marker. The patient was treated with full dose of CHOP regimen. However, adriamycin was replaced with pirarubicin and the dose of the other drugs were reduced for the subsequent 4 courses because of severe leukocytopenia, thrombocytopenia, hepatotoxicity, and alopecia after the first course of the treatment. The patient showed complete remission and discharged on March 12, 1996. He, after 17 months, has no signs of recurrence. We reviewed 43 Japanese cases previously reported as renal malignant lymphoma. It is increasing in Japan especially in elderly. The 2-year survival is 26.6%.

(PURPOSE). To determine the efficacy of extraperitoneal laparoscopic adrenalectomy for patients with adrenal tumor, the clinical results of 9 patients treated with this procedure were analysed. (PATIENT AND METHOD). Between July 1994 and March 1995, we have performed extraperitoneal laparoscopic adrenalectomy using the modified Gaur technique of balloon dilatation of the retroperitoneum in 4 men and 5 women with unilaterla small adrenal tumor who were 30 to 79 years old (mean age 56 years). Preoperative diagnosis was primary aldosteronism in 2, 18-hydroxycorticosterone producing adnoma in 1, pre-Cushing syndrome in 5, and nonfunctioning adrenal tumor in 1 patient. The operations were performed with the patients on lateral position and 4 torocars were positioned. The retroperitoneal space was first dissected bluntly by the index finger and a balloon dissector through a small skin incision, and the retroperitoneal space was insufflated with carbon dioxide at the pressure of 10 to 12 mmHg. After the dissection of the adrenal gland, adrenal vein was clipped and transected. The completely freed adrenal gland was enclosed in an entrapment sack and removed en bloc through the open laparoscopy wound. (RESULTS). All 9 procedures were successfully performed. The mean estimated blood loss and the mean operating time were 53 ml and 168 min respectively. There was no intraoperative complication. A postoperative retroperitoneal hematoma was observed in one patient, however it spontaneously resolved without surgical management. (CONCLUSION). In open adrenalectomy, the benefit of the extraperitoneal approach (excluding patients with pheochromocytoma or bilateral lesions) have already been established elsewhere. Although the working space is smaller than that of peritoneal approach, and the surgical techniques are slightly more difficult, extraperitoneal laparoscopic adrenalectomy promises to be safe and a minimally invasive treatment for patients with unilateral small adrenal tumors except for pheochromocytoma.

Purpose: Laparoscopic nephrectomy has become widely performed because of its minimally invasive nature. We have performed laparoscopic nephrectomies for non-functioning kidneys and laparoscopy-assisted radical nephrectomies for renal carcinomas. Recently, we have successfully performed laparoscopy-assisted transperitoneal living related donor nephrectomy for kidney transplantation. To determine the efficacy of laparoscopy-assisted live donor nephrectomy, we investigated the clinical results of 2 patients operated upon with this new operation., Patients: Case 1 was a 64-year-old healthy male and the left kidney was removed for his son who had a history of 4 months hemodialysis. Case 2 was 67-year-old healthy female who decided to donate her left kidney for her son with the history of 3 years and 2 months hemodialysis., Methods: An upper abdominal midline incision of approximately 10 cm in length was made. Two retractors were attached to either side of the midline incision. The abdominal wall was raised by suspending these retractors from a special hanger. Then three trocars were introduced. The Gerota's fascia was incised and the kidney was suspended by grasping the perirenal fatty tissues. The renal artery and vein were carefully isolated without any manipulations of the kidney (non-touch method). After the transection of the ureter, the renal artery was ligated with a free tie of 1-0 silk and a suture ligature of 3-0 silk and the renal vain was clamped with a Satinski forceps. Immediately after the transection of the renal pedicle, the kidney was irrigated and transplanted to the right iliac fossa of the recipient in the usual fashion. A pen-rose drain was placed in the retroperitoneal space and the posterior peritoneal membrane was completely closed with 3-0 silk interrupted sutures., Results: The mean operating time was 298 minutes and the mean blood loss was minimal. The average time of warm ischemia and cold ischemia of the graft were 4.5 minute and 37 minutes, respectively. There were no complications during either the operation or the postoperative period in both patients. The donors began oral intake and ambulation within 48 hours and resumed their normal daily activities by postoperative day 6.5 on average. Postoperative recovery of the patients were far faster than that of the patients receiving open donor nephrectomy. The graft functions were also excellent. The serum creatinine concentration of the recipients fell down to 0.82 mg/dl and 1.02 mg/dl at the third postoperative day., Conclusion: Laparoscopy-assisted live donor nephrectomy might be advantageous for kidney transplantation because of its minimally invasive procedure.

From March 1989 through December 1989, 123 patients, 9 to 78 years old, were treated by extracorporeal shock wave lithotripsy (ESWL) with the Wolf Piezolith device. Outpatient treatment was performed routinely. Anesthesia was not required in all of the patients. No analgesia or sedation was given routinely. When pyuria had been found before treatment, a course of prophylactic oral antibiotics was given. Treatment consisted of 2000 to 6000 shocks in adults. The need for re-treatment was decided on the basis of the follow up X-rays. Fragmentation into particles 5 mm in size or less occurred in 144 of the 149 renoureteral units (96.6%). Unfragmented stones were treated successfully by the combination therapy of ESWL and fiberoptic transurethral nephroureterolithotripsy (f-TUL). Of 144 renoureteral units, 3-month follow-up data are available for 96. Among the 96 units, the rate of being free of stones was 67 per cent for renal stones and 96 per cent for ureteral stones treated in situ. The over-all rate of being free of stones was 80.2 per cent. There were no significant complications. Ultrasound imaging has proved to be as effective as X-ray imaging. Outpatient ESWL with the Wolf Piezolith device is considered to be safe and efficient for the initial treatment of urinary stones. On the other hand, ESWL monotherapy is not sufficient for the treatment of complete staghorn calculi or long-term impacted ureteral calculi. We think that the combination use of ESWL and f-TUL is the most effective procedure for treatment of complicated stones.
