[Vascular assessment before kidney transplantation. Role of computerized helical tomography].

OBJECTIVE: To present our experience with helical CT for vascular assessment prior to renal transplantation. METHODS: In our hospital, all candidates to renal transplantation are referred to the Urology Transplant Unit for previous assessment. For the past 3 years, patients with multiple arterial calcifications (non linear) have been evaluated by helical CT with three-dimensional reconstruction of the calcification densities, which provides an accurate representation of the lesion. RESULTS/CONCLUSIONS: Pretransplant evaluation has been fundamental for individualized planning of the renal transplant surgery. The use of helical CT is extending in our field and it has also been utilized in graft donor assessment. In our experience, the extent and thickness of arterial wall calcifications are accurately depicted by helical CT. These findings could have an important significance when making pre and perioperative decisions in renal transplantation.

[Renal artery stenosis in the transplant patient].

OBJECTIVE: To present our experience in the diagnosis and treatment of renal artery stenosis in kidney transplants. METHODS: A review of 601 renal transplants performed in adults showed 32 cases of renal artery stenosis. The diagnostic techniques utilized were arteriography in 18 patients, DIVAS in 15, echo-Doppler in 11 patients and MAG with captopril test on two occasions. RESULTS: Arterial hypertension was the most common symptom (92.8%), alone (53.1%) or in association with impaired renal function (43.7%). 46.8% of the cases could be managed by drug therapy. Percutaneous transluminal angioplasty was performed in 14 patients. Surgery was required on two occasions. CONCLUSIONS: The incidence of renal artery stenosis in our series of renal transplants in adults up to 1997 was 5.3%. Arterial hypertension with or without impairment of renal function was the most common symptom. Currently, echo-doppler and MAG with captopril test are the most widely utilized diagnostic techniques. Percutaneous transluminal angioplasty is the treatment of choice in renal artery stenosis when arterial hypertension is refractory to drug therapy. Good results are achieved in 57%, although it is not free from complications. In case of failure, revascularization surgery is the alternative approach.

[Surgical treatment of obstructive disease of the transplanted kidney].

OBJECTIVES: To review renal graft obstruction post-transplantation and its surgical management. METHODS/RESULTS: Our experience and those of other Spanish centers are analyzed and the literature reviewed. The different causes of obstruction following transplantation are briefly analyzed and the advantages and disadvantages of the different therapeutic options are discussed. CONCLUSIONS: Graft obstruction post-transplantation continues to be an important challenge to the urologist. However, in most of the cases the therapeutic alternatives are relatively standardized and achieve satisfactory results.

[Cancer and kidney transplantation].

The higher risk of developing malignant tumours in transplanted patients is a fact widely acknowledged over the last decade. This paper includes an analysis of our series and a review of the literature. Cancers developed by the transplanted patient or "de novo" cancers and, within this group skin and lip cancer (58%), are by far the most frequent ones. Their biological behaviour is, in general, more aggressive than similar ones in non-transplanted population. Also, different incidence rates and behaviour have been established depending on the immunosuppressive regime given to the patient. Most common pre-existing carcinoma was renal cancer (one third of cases). When these patients had been adequately treated before the transplant, the minimum disease-free interval that has to elapse to be included in a waiting list will depend on the type of tumour. Transferred tumours are the least frequent but more worrying ones due to both their clinical and legal implications. In view of the existing evidence, it is of particular relevance to insure the primitive nature of any CNS tumour as well as the absence of tumoral disease in young females who die of brain haemorrhage.

[Non-venereal sclerosing lymphangitis of the penis].

Non-venereal sclerosing lymphangitis of the penis is a rare condition that affects the distal lymphatics of this organ. It has been reported to be frequently associated with trauma to this area and, although it has a minimum inflammatory component, its etiology is unknown. A serpinginous nodular lesion in the sulcus coronarius penis may be observed by the patient. Because it is generally self-limiting, treatment is initially conservative and surgical excision is performed only if symptomatic lesions persist. The present study reports an additional case. The literature is reviewed and the possible etiopathogenic mechanisms and therapeutic alternatives are discussed.

[Leydig cell tumor].

We report on a 44-year-old patient with Leydig cell tumor of the testis that had been incidentally detected following orchidectomy for a tumor. The clinical, hormonal and histological criteria currently used to distinguish the malignant from the benign form of this tumor and the different therapeutical alternatives are discussed.

[Oncocytic cell tumor. Problems, diagnosis, therapy].

Renal oncocytoma is an uncommon tumor. At least 203 such cases have been reported. This urologic condition represents a diagnostic difficulty and because its natural history has not been elucidated, its treatment remains a controversy. Two recent cases of renal oncocytoma seen at our Urology Service prompted us to review the literature and analyze the diagnostic methods, therapeutic approach and its prognosis.

[Changes in the dimensions of the remnant kidney after nephrectomy of the pathologic contralateral kidney in adults].

Compensatory renal hypertrophy is a process that has been known since Gustav Simon performed the first nephrectomy procedure in man in 1869. The present study reviews the literature and analyzes the factors relating to this process and its morphologic features. It has been reported that the degree of renal hypertrophy depends, among other factors, on the amount of nephrons lost as well as adaptative capacity of the surviving kidney when the pathologic kidney is removed. The present study also reports the changes in size of the surviving kidney observed at 6, 30, and 90 days after removal of the pathologic kidney in 40 patients. The results show a significant increase 6 days following nephrectomy and a significant decrease at 30 days to mean values higher than those of the preoperative evaluation. Ninety days after nephrectomy, these values significantly increase again but do not reach the same levels as those observed 6 days after nephrectomy. These findings are ascribed to the hemodynamic changes resulting from nephrectomy. These manifest immediately after the procedure and remain unchanged for days and subsequently the structural changes of renal hypertrophy prevail.

[Extrarenal complications in kidney transplant. Our experience].

Since renal transplantation was introduced in the treatment of chronic end-stage renal failure, we have observed that extrarenal complications have an important role in transplant morbidity and mortality in hospital where kidney transplantation is not an uncommon procedure. The present study reports on the statistical data relative to extrarenal complications in kidney transplantation observed at our hospital, highlighting infectious, GI, respiratory, and hematologic complications because of their incidence.

[Echographic studies in renal transplant. Our experience].

The present study briefly reports our experience in the evaluation of renal transplantation by conventional and pulsed Doppler ultrasound. We advocate the use of both imaging techniques in these patients because these are safe, reliable, easy-to-use, reproducible noninvasive imaging techniques that afford a high diagnostic yield.

[Kidney transplant in children. Our experience].

We report on our experience comprised of 21 kidney transplant procedures (20 from cadavers and 1 from a living donor) performed at the Urology Department of our hospital. Of these, 11 remained functional 2 years following transplantation. Of the 10 transplants that failed, 3 were due to arterial thrombosis, 1 from venous thrombosis, 2 from late rejection, 1 from septic necrosis of the vascular suture area, and 1 because the arterial intima had been "swept away" by transluminal dilatation. We underscore the high incidence (33%) of arterial hypertension in these children submitted to renal transplantation and the good response to treatment with hypertensive agents and/or transluminal dilatation. We emphasize the usefulness of duplex-Doppler ultrasonography in evaluating arterial blood flow and in the diagnosis of arterial stenoses. The surgical techniques, complications, and evolution of transplanted kidney function are discussed.

[Immediate surgical complications after 270 renal transplants. Experience and results].

The present study reports on the early surgical complications observed in 270 renal transplants performed from 1978-1987. A total of 34 (12.5%) surgical complications were observed in the early postoperative period (1 to 6 weeks posttransplant). Among the most prevalent were postoperative hemorrhage, most of which were ascribable to blood coagulation disorders from heparin administration necessary to perform hemodialysis in these patients, and thrombus formation during the initial stages of our experience. Ten patients had urinary fistulas that were resolved in different ways. We advocate performing pyelo-pyelic anastomosis to the excretory tract whenever possible because of the good results achieved with this procedure.

[Analysis of the reasons for non graft initial function in our series of the last eleven years].

UNLABELLED: FUNDAMENTAL: [corrected] To know which risk factor of delayed graft function in our patients. MATERIAL AND METHODS: We analyzed 469 transplants, 270 had good initial function and 199 had delayed function graft. Variables studies in booth groups were: age, sex and dead cause of donant, type of extraction and place were it was done, implantation side, vases multiple, isquemia times, age and receptor sex, HLA compatibility, retransplant, Ac Anti-VHC, PTH pretransplant, years in waiting list, hiperinmunization, number of transfusion, and type of inmunosupretion. RESULTS: Univariant study: significant differences were found in age and dead cause of donant, isquemia times, years in waiting list, hiperinmunization, number of transfusions, and HLA-B incompatibility. Multivariate study: we have significant differences in age of donant, could isquemia time, years in waiting list, cuadruple? Inmunosupretion. CONCLUSIONS: Results suggest to short could and revascularization isquemia time as possible, and use less nefrotoxic inmunosupretion pautes in high-risk patients.
