[Hematuria and sharp renal failure as debut of secondary bladder amiloidosis. Presentation of a new case and revision of the literature].

The primary bladder amiloidosis is an uncommon pathology, not existing in the world more than 150 published cases, being even more exceptional the secondary bladder amiloidosis being described around 25 cases. The secondary bladder amiloidosis associates in most from the patients to arthritis reumatoide of long evolution. The diagnoses clinical it is difficult, being necessary the differential diagnosis with the bladder tumour. The pathological study and inmunohistochemics, confirm the diagnosis. We present the case of a patient that I debut with frank hematuria, hemodynamic uncertainty and renal inadequacy that it required combined treatment, doctor and surgical for the resolution of their square.

[Myofibroblastic tumor of bladder].

The myofibroblastic tumor, is a mesenchymal benign tumor of exceptional character, being its localization but habitual it is the lung; while its appearance in the bladder, is exceptional, not existing but of 100 published cases, of this tumor type in the bladder. This tumor type that clinic and radiologics, behave as a wicked tumor. The pathological diagnosis is complex, due to its similarity with the sarcomas, being necessary to appeal to the inmunohistochemics for a I diagnose of certainty. The treatment by means of wide resection is usually enough not existing any case of metastasis at the present time at distance, neither of malignization. We present a new case of this neoplasm, carrying out a wide bibliographical revision.

[Laparoscopic bilateral nephrectomy of native kidney in kidney transplantation carriers].

Severe vesicouretheral reflux sometimes causes terminal renal failure which then requires renal transplantation. In these patients it may be necessary to perform bilateral nephrectomy when associated to serious hypertension or urinary infections with a significant clinical impact. This paper presents the clinical picture of a patient with a corpse renal transplantation, due to terminal renal failure secondary to reflex nephropathy, in whom it was necessary to perform bilateral nephrectomy due to the uncommon urinary infections requiring hospitalization for treatment. The bilateral nephrectomy was done through transperitoneal laparoscopic approach, using seven points for trocars introduction. The procedure lasted 4 hours and the patients was discharged within 48 hours with no complications. Accumulate experience in the use of laparoscopy in urology has allowed this technique to be feasible. After designing the experimental model, our group has had the chance to accomplish laparoscopic nephrectomies in humans. We believe that this is the first case of bilateral nephrectomy conducted in our country using the laparoscopic approach.

[Malignant neoplasms in kidney transplant recipients].

OBJECTIVES: This study is a retrospective analysis of malignant tumors in renal transplant recipients. A review of the pertinent literature allowed us to develop a protocol for early diagnosis and treatment of tumors arising in this group of patients. METHOD: 171 renal transplants have been performed over a period of 4 years. The renal grafts had been harvested from cadavers (mean age 32.01 years). All recipients (mean age 44.3 years) were immunosuppressed with prednisone, azathioprine and cyclosporine A. RESULTS: Five "de novo" malignant tumors were detected in 4 patients (2.3%). The tumors were basal cell epithelioma of scalp and gastric adenocarcinoma in the same patient, lymphoma of the CNS, carcinoma of the breast and adenocarcinoma of the colon. The patient with a gastric adenocarcinoma died after a disease-free interval of 28 months, following treatment of the cutaneous lesion. The patient with lymphoma of the CNS had died before receiving treatment and the remaining 2 patients are disease-free at 12 and 6 months' follow-up. CONCLUSIONS: The possible role of viruses is underscored. Transplant recipients should be followed very closely since they are likely to develop a tumor, especially of skin and lips. The importance of gynecological and neurological assessment and control of native kidneys cannot be overemphasized. Performing an autopsy on donors can reduce the risk of transplanting tumors. Kidney transplantation should be delayed if the graft recipient has a tumor. Correct diagnosis and treatment will enhance the results in these patients.

[Retroperitoneal laparoscopic nephrectomy: a case report].

Presentation of the first exclusively retroperitoneal laparoscopic nephrectomy performed on a female patient diagnosed with chronic pyelonephritis in the right kidney who referred frequent discomfort in the ipsilateral lumbar fossa as well as sporadic urinary infections. The entire procedure was performed without entering the peritoneal cavity, creating a space in the retroperitoneum, using for that hydrostatic dilation following Gaur's recommendations and introducing in that space a total of 4 trocars. Surgery lasted 3 hours an 35 minutes, with a post-operative stay of 3 days; the anaesthetics used after surgery was minimum and patient's return to her usual daily activities was almost immediate after discharge. Considering our group's previous experience in laparoscopic nephrectomies, both in humans (another 3 cases) and experimental surgery (18 pigs), we believe retroperitoneal approach is a huge step ahead in urological laparoscopic surgery, since this is the typical approach in our specialty and allows a closer contact with the condition being treated. On the other hand, the combined retro- and transperitoneal accesses will involve-are already involving-a greater variety of laparoscopic techniques in urology.
