Introduction: Partial nephrectomy (PN) is the standard treatment for small and localized kidney tumours (cT1). One of the controversial aspects regarding this technique is the management of affected/positive resection margins. We present the long-term oncological results in patients with PSM after PN managed conservatively., Material and Methods: There were 207 PN performed in our centre between 1990 and 2011. 17 patients presented PSM. 2 patients were excluded from the study due to completion nephrectomy afterwards. Follow-up was was done with abdominal contrast-enhanced computed tomography every 6 months for the first 2 years and subsequently, once a year. Cancer-specific survival and disease-free survival were calculated with the Kaplan-Meier method., Results: The median age was 62 years (RIQ: 55-71) and the mean tumour size was 34.8 (10-77) mm. Histopathological results were: 6 (40%) clear cell RCC, 4 (26.7%) papillary, 3 (20%) chromophobe and 2 (13.3%) oncocytic. The pathologic stages were: 11 (73.3%) pT1a, 1 (6.7%) pT1b and 3 (20%) pT3a. The median follow-up was 84 months (IQR 72-120). 2 patients had metastatic recurrence and this was the cause of death. The first one had recurrence at 112 months and the second one at 59. 5-year CSS and RFS were 87.5% and 93.3% respectively., Conclusions: In our experience, patients with PSM after PN can be managed conservatively with satisfactory long-term oncological outcomes., (Copyright © 2019 AEU.

We present the case of a renal pseudotumor corresponding to a esteatonecrotic granuloma, secondary to an enolic acute pancreatitis a few months ago. The main caractheristics, diagnosis and terapeuthics of the renal pseudotumors are discussed with the case report of a 60 year old man who presents a renal mass founded incidentally at a control computed tomography.

Unlabelled: The kidney as an apo-exocrine organ has two important functions: the control of homeostasis and arterial blood pressure. Any pathological disorders witch alters the renal blood flow results in two consequences: renovascular hypertension and renal insufficiency. Renal revascularization looks for with priority the improvement of renal function; the good response and control of hypertension shall come after. The goals of this paper is to actualize the sophisticated diagnostic methods (Angiography, Eco-Doppler, AngioCT, AngioMR, Angioscopy; and the use of contrast potential-mediums), functionality tests (RN and MR with Captopril) and management (Percutaneous transluminal angioplasty, simple or covered Stents, Embolizations, Occlusive balloons, Fibrinolysis and Trombus Aspiration; direct Arterial Surgery and renal Autotransplantation) of different renovascular diseases. (Blunt renal injuries, Stenosis, Aneurysms. A-V fistuls, Acute Occlusions or arterial and venous, Thrombosis. Nutcraker Syndrome). The possibility of the presence of an inverse venous Fraley's Syndrome is presented and discussed., Conclusions: A controversy of the last technical methods are established and discussed and a Guideline is recommended for each renal vascular disease.

Introduction and Objectives: Renal Cell Carcinoma (RCC) represents 3% of all neoplasm. The growing incidental diagnosis of small renal tumor has allowed the application of nephron sparing surgery (NSS), even in those cases with a normal contralateral kidney. We present the results of NSS at our center in the last decade., Material and Methods: A retrospective analysis of all NSS that were made at our center in cases of renal masses. Difference is made between elective surgery (tumors less than 4 cm with a normal contralateral kidney) and obligatory surgery (all other cases)., Results: From 1990 since 2000 a total of 65 NSS were made from a total of 436 surgeries for renal tumors (14.9%). In 22 patients NSS was obligatory, while in 43 was elective. Mean (SD) age was 59.1 years (+/- 11.7), mean tumor size 3.4 cm (+/- 1.4), mean hospital staying was 9.2 days (+/- 7). Renal normothermic ischaemia was use during surgery in all cases, with a mean ischaemic time of 25.7 min. Nine tumors (13.8%) were benign. Morbidity: 10.8%. Mortality: 1.5%. The cancer specific survival at 36 months of follow-up (mean 37.4) is 98.4% and global survival is 90.3%., Conclusions: Nephron Sparing Surgery is a valid alternative in the treatment of RCC, specially for tumors less than 4 cm in diameter and having a normal contralateral kidney; NSS is also an effective technique for patients bearing renal tumors in a solitary kidney.

Primary actinomycosis of the bladder is an infrequent presentation of this condition. The main concern is obtaining a differential diagnosis from tumours of the bladder and the subsequent impact this has on the therapeutic choices. Contribution of one case report of a male patient with actinomycosis of the bladder, with remarks on relevant diagnostic (including differential diagnosis) and therapeutic data.

Background: Because of the shortage of kidneys available for transplantation, we began in 1985 to harvest kidneys from non-heartbeating (NHB) donors., Methods: We compared the results of a group of 66 kidney recipients from NHB donors (NHB group) with 122 kidney recipients from heartbeating donors (HB group). We analyzed, in the NHB group, the influence of ischemia times in graft survival and we tested the best cut-offs by receiver operating characteristic curves. We also studied, using a univariate and multivariate Cox hazard model, the capacity of different variables to predict graft loss., Results: Patient and graft survival were similar in both groups during the follow-up. The percentage of delayed graft function was the only significant difference between both groups (NHB group 62% vs. HB group 32%; P=0.0001). Delayed graft function, in the NHB group, is influenced by the warm ischemia time, which is directly related to the number of days to achieve a serum creatinine<300 mmol/L (P=0.0001). The best cut-off times in this group were 45 min for warm ischemia time and 22 hr for cold ischemia time. Recipients have a greater likelihood of losing the graft beyond those limits (P=0.017, relative risk: 7.3). The incidence of acute rejection was similar in both groups, and it was the only predictor factor of graft loss in the complete series of patients (P=0.0001), in the NHB group (P=0.007), and in the HB group (P=0.02)., Conclusions: Reducing the incidence of acute rejection and shortening ischemia time are conditions needed to guarantee a long graft survival of kidneys from NHB donors.

Presentation of the results obtained with extracorporeal shock wave lithotripsy (ESWL) applied to 3173 ureteral lithiasis with a Dornier HM-4 equipment. Location of lithiasis was pyeloureteral junction (329), lumbar ureter (1068), sacral ureter (238), iliopelvic ureter (1474) and "lithiasic path" (64). All lithiasis were treated in situ. Treatments were carried out ambulatory with no anaesthesia. Treatment/lithiasis rate was 1.3. Percentage of stone-free patients with ESWL alone was 79.2% after the first session, and reached 86.14% with retreatment. Percentage of success for lithiasis in pyeloureteral junction was 81.8%, 79.7% for lumbar ureter lithiasis, 80.09% sacral lithiasis, 90.10% iliopelvic ureter lithiasis and 79.9% for those in the "lithiasic path". 12.6% lithiasis required post-ESWL auxiliary manoeuvres. Post-ESWL minor complications (pain, vegetations) occurred in 5.6% cases and major complications (obstruction, fever, sepsis) in 2.9%. The factors influencing lithiasis fragmentation were the number of shock waves and the lithiasis duration. Size of lithiasis and presence or absence of ureteral catheter had no influence. These results suggest that ESWL is an effective method for managing ureteral lithiasis.

Objectives: The shortage of renal grafts has led to the search for other alternatives. The use of grafts from non-heart-beating donors (NHBD) can increase the number of transplants 8% to 20%. Clinical studies conducted by different groups, have found that the long-term graft and patient survival are not different from those of recipients of kidneys from heart-beating donors (HBCD)., Methods/results: The long-term results of a group of 52 recipients of NHBD kidneys were compared with those of 98 recipients of HBCD grafts. There were no differences in donor and recipient ages, HLA compatibility, reperfusion and cold ischemia times. There were no differences in the incidence of rejection episodes or non-functioning kidneys. Warm ischemia between 30 to 60 min or < 30 min did not influence the incidence of non-functioning kidneys. However, NHBD graft recipients had a higher incidence of acute tubular necrosis (67% versus 46%), recovers of renal function was slower, the duration of oliguria was longer and dialysis was required. The 8-year actuarial survival data were similar for both groups; 65% for the NHBD and 70% for the HBCD graft recipients., Conclusions: We can conclude that NHBDs are an important source of donor kidneys. The 12 points established by The First International Workshop on Non-Heart-Beating Donors which appear at the end of the present article are embodied in the Treaty of Maastricht regulations of organ transplantation from non-heart-beating donors.

The kidney is frequently involved in penetrating abdominal injuries, and less so in closed abdominal traumatism. This paper presents one case of major renal trauma with total renal fracture and development of urinoma that separated both segments that, after a minimally invasive manoeuvre (percutaneous drainage), evolved favourably thus avoiding a surgical procedure which, quite reasonably, would have led to nephrectomy.

In 661 renal transplantations, 2 potentially migrated tumours (0.38%), 5 preexisting neoplasias (0.76%), and 31 "de novo" tumours were seen in 29 patients (4.4&). Although of very low incidence, the likelihood of tumour migration from elderly donors, given the circumstances surrounding removal, offers a high risk. None of the preexisting neoplasias relapsed following transplant. The highest prevalence was seen in skin (40%), lung (13%), kidney (13%) and bladder (6.6%) "de novo" tumours. Incidence of lymphoma was low. Dominant etiological factors of the recipient were older age, effective and tolerated immunosuppression, viral infections, environmental agents and antigenic stimulation of the graft. Skin lesions have responded well to local treatment, without need to discontinue immunosuppression, a measure that is mandatory in other malignant tumours. Also, the conclusions of a round table during the 25th National Meeting of Urotransplantation of the Spanish Association of Urology held in 1994 on "Oncology and Renal Transplantation" are presented.

The nutcracker phenomenon consists in the compression of the left renal vein by the aortomesenteric clamp. This is an infrequent cause of haematuria. The present paper presents one case of nutcracker phenomenon showing haematuria after mild accidental lumbar bruising, with arteriographic diagnosis. CAT assessment showed a mark in the lumbar ureter as well as peripyelic and periureteral varices.

Analysis of the indications for transplantectomy and its complications over a 12-year period. Over a total of 159 failure grafts, we performed 53 transplantectomies (33.3%). The percentage of complications was 16.9%. Three patients died (5.6%) during the more or less immediate post-operative period. In our experience, consistent and prolonged maintenance of immunosuppression should avoid the need for transplantectomy in a high percentage of grafts. Only 15 transplantectomies were made on 104 failure grafts after 6 months (14.4%). Our short but successful experience with embolization of 2 rejected grafts confirms the validity of this conservative alternative versus conventional surgical transplantectomy in selected cases.

We reviewed the cases of angiomyolipoma that had been diagnosed and treated in our urology services from 1978 to 1991. The study showed a higher incidence in the females; it frequently presented as a solitary tumor; a high specificity was found for the US (hyperechoic mass) and CT (areas of low attenuation ratio) findings. Owing to these diagnostic techniques, conventional surgery is no longer the only treatment. Embolization is considered to be the first therapeutic approach.

The urinary tract is rarely affected by endometriosis, urinary bladder being the most common location. This paper presents one case of advanced extrinsic endometriosis which initially presented as obstructive pyelonephritis. The diagnostic methodology, including uro-tomographic imaging, is evaluated. Although good results have been reported with hormone-therapy, we support the surgical approach sanctioned by the patho-anatomical findings.

Presentation of three cases of haemodialysis patients with acquired cystic renal disease (ACRD) who, over the course of their illness, developed clear cells renal carcinoma. The paper emphasizes the common association of these two entities and the need to consider ACRD cases as patients at high risk of developing renal neoplasia.

Evaluation on the incidence of Acute Renal Failure (ARF) from a total of 41 corpse renal graft receptors, 20 of which received perfusion with mannitol solution at 400 mOsm/kg (Group 1) and 21 the same mannitol solution plus allopurinol (Group 2). No significant differences were present between both groups when they were analyzed for ARF incidence (15% vs 23.8%); overall incidence was 19.5%. 24-hour initial diuresis was shown to be an excellent predictor for long-term graft functionality. We can conclude that the addition of mannitol to the perfusion solution contributes decisively to reduce post-transplantation ARF, while addition of allopurinol does not have further beneficial effects.

Renal angiolipomas are the most frequent benign renal tumours. Since ultrasound techniques have been in use to study algetic lumbar syndromes, their symptomatic appearance has decreased. Most authors agree that CAT has a 100% specificity. The paper contributes one case of renal angiomyolipoma isolated in a 39-year old woman, its primary interest being the clinical presentation, within an extensive septic milieu of urinary origin, the intra-operative diagnosis, considering the previous false-negative echography and dubious tomographic diagnoses, and the findings of regional node invasion, all exceptional states in the reviewed literature.

Retrospective analysis of the results from corpse renal transplantation, under immunosuppressive therapy with cyclosporin in a group of 58 elderly receptors (greater than or equal to 50 yr). The results are compared with those obtained in 152 receptors under 50 year of age transplanted during the same period of time (1984-1988). No statistical differences were seen between both groups regarding immunosuppressive therapy, number of transfusions, HLA histocompatibility, number of transplantations and percentage of hypersensitive patients. Incidence of rejection is significantly higher in the younger patients group, as well as graft loss due to immunological reasons. Mortality was significantly higher in the elderly group. Actuarial survival of the graft after two years is similar in both groups. It is concluded that in the era of cyclosporin, the receptor's age should still be considered a risk factor and, therefore, that maximum precautions should be taken in order to detect any additional risk factor within this group in a strategy to improve their survival.

Extensive literature review on the current state of organs preservation; solutions and methodology. Major advances in immunosuppression methods and the ongoing increase in the number of renal transplants encourage the search and investigation of better preservation techniques. Continuous pulsatile perfusion and perfusion plus hypothermal storage represent the two most frequently used techniques nowadays. In spite of the advantages shown by the former in the case of prolonged cold ischemia, hypothermal storage remains as a practical technique widely used in our environment.

Retrospective review of 126 urinary by-passes performed in our service over the last 15 years where efficacy and complications arisen from the ureteroileal by-passes, ureterosigmoidostomy and skin ureterostomy are analyzed. Patients were found to be pre-operatively homogeneous with no statistically significant differences with regard to age, renal function or previous radiotherapy, except in the case of ureterostomies which are always initiated from a poorer renal function and general condition. It was concluded that there was no difference between the various Bricker types according to the anastomosis, which allows joint a comparison with other groups. After three months, Bricker's showed better radiologic evolution than Goodwin's (p less than 0.08) and a statistically lower number of complication (p less than 0.05) therefore establishing they should be the choice procedure versus any other type of by-pass. Literature review with regard to results and conditions of container reservoirs and vesical substitutions, evaluating their contraindications within the neoplastic scope and/or psychosocial range, as well as comparing the reflux, stenosis and infection rates with our series, make the ureteroileal by-pass a technique entirely legitimate at present.

Renal Vein Thrombosis is an uncommon entity associated to various clinical conditions which develop in hypercoagulant states. The paper describes one case of idiopathic thrombosis of the renal vein in an adult patient, also making a review of the literature on this clinical syndrome and its diagnostic and therapeutic aspects.

Between 1974 and 1988, 35 testicle germinal tumours, 16 seminomas and 19 non seminomas, were studied. Mean age in seminoma cases was 34 years and 26 in non seminoma cases; the former were mainly presented as located stages at the time of diagnosis (75%) while the latter were, on the contrary, mostly stages II and III. Following orchiectomy, all histologically pure seminomas received radiotherapy with the exception of two cases. All of them are presently free from the disease with an average follow-up of 2.8 years (range 0.5-5 Yr.) Radiotherapy continues to be proposed as first choice therapeutic action for siminomas in located stages, although we do not disagree with other more conservative possibilities. In the non seminoma group, all three patients diagnosed in stage I were clinically controlled without supplementary therapy, two of them having a recurrence during the first year of follow-up, but currently free of the disease after chemotherapy and surgery of residual masses. Of the three non seminoma patients in stage II, with negative post-orchiectomy markers, two underwent lymphadenectomy and the other one only chemotherapy. In the remaining group of non seminoma patients, and always after an orchiectomy, chemotherapy was performed as first choice therapy, although rescue lymphadenectomy was required in eight cases. Chemotherapy schemes with cisplatin have relegated to a second level any other therapy for the non seminoma patients. The excellent response and reduction of side effects allow the adoption of more conservative attitudes. This paper explains our retrospective study and, following a wide review of exiting literature, discussed any conflictive prognostic and therapeutic items.

We make an evaluation of 66 ureteroscopies (URS) carried out in our Service over a period of 18 months. In 55 cases it was done for therapeutic purposes in ureteral lithiasis, and in 11 cases it was for diagnostic purposes. In the treatment of lithiasis resolutive effectivity at the first attempt was 68%, in 9% ureterolithotomy had to be performed due to the impossibility of approaching the calculus, and in 23% supplementary treatment was carried out by means of external litrotripsy. In the diagnostic field, effectivity was 72%. Notable complications arose in 6 cases (9%), 6 ureteral perforations, in three of which a urinoma was formed, all settled with a double J catheter. Open surgery was not resorted to in any case. No sequelae were observed and this technique therefore showed itself to be safe and effective.

The introduction of new diagnosis techniques has made the study of the suprarenal gland much more accessible. In particular, ultrasonography, CAT and MRI have contributed to the increased detection of suprarenal masses by chance, and this raises problems when it comes to deciding the attitude to take to the diagnosis of these masses. We present nine suprarenal tumours, most of which appeared in the course of follow-up of patients suffering from carcinoma of the bladder. On detecting a suprarenal mass, we carry out a morphological study with CAT as well as determination of hormonal activity and puncture with cytology of the mass, according to the schema proposed by Copeland. We comment on the most significant clinical aspects and on the criteria of action proposed by various authors.
