    INTRODUCTION: In kidney transplantation, anatomical vascular and excretory anomalies may represent causes of failure. Today's surgical techniques have made the most of the organs with anatomic anomalies and iatrogenic injury successfully used for transplantation. MATERIALS AND METHODS: From January 2000 to June 2006, we harvested 230 kidneys, of including 88 kidneys (20%) with vascular, urinary, or vascular-urinary anomalies; 64 kidneys were implanted and 15 were sent to other transplantation centers. Only 9 kidneys were not appropriate for transplantation. RESULTS: All patients who received kidneys with the above-mentioned anomalies were carefully examined after the transplantation and short-term and long-term complications were evaluated with respect to controls without anomalies. DISCUSSION: Renal anatomic anomalies are frequently observed during kidney transplantation and may produce postsurgical complications. However, the presence of these anomalies does not necessarily imply the impossibility of using the kidney for a transplant, especially because of improved surgical techniques. Our experience in transplantation procedures showed that even if kidneys present the above-mentioned anomalies they can still be considered appropriate for transplantation when we perform a correct harvesting/back-table transplant surgery. So vascular and urinary anomalies have to be considered always an incentive to research new surgical solutions and to perform a careful surgical technique

    Transplantation and young surgeons in italy

    The relation between young surgeons and transplantation has always been a "love and hate" one. Until a few years ago this branch of surgery was seen as pioneering, with extreme and and extensive training, and was reserved to few elected members. Nowadays things are different. In this article we try to understand the true reasons that young Italian surgeons avoid transplantation surgery

    R0 surgical resection of giant dedifferentiated retroperitoneal liposarcomas in the COVID era with and without nephrectomy: A case report

    : Retroperitoneal sarcomas (RPSs) are rare findings that can grow into large masses without eliciting severe symptoms. At present, surgical resection is the only radical therapy, whenever it can be performed with the aim to achieve a complete removal of the tumor. The present report describes two consecutive cases of RPSs that resulted in dedifferentiated liposarcomas (DDLPSs) and these patients underwent R0 surgical resection with and without a nephron-sparing procedure. The diagnostic workup, the surgical approach, the impact of late surgical management due to the COVID pandemic and the latest literature on the topic are discussed and analyzed. The patients, who refused to undergo any medical examination during the prior 2 years due to the COVID pandemic, were admitted to Federico II University Hospital (Naples, Italy) complaining about weight loss and general abdominal discomfort. In the first case, a primitive giant abdominal right neoplasm of retroperitoneal origin enveloping and medializing the right kidney was observed. The second patient had a similar primitive retroperitoneal giant left neoplasm, which did not affect the kidney. Given the characteristics of the masses and the absence of distant metastases, after a multidisciplinary discussion, radical surgical removal was carried out for both patients. The lesions appeared well-defined from the surrounding tissues, and markedly compressed all the adjacent organs, without signs of infiltration. In the first patient, the right kidney was surrounded and undetachable from the tumor and it was removed en bloc with the mass. The second patient benefited from a nephron-sparing resection, due to the existence of a clear cleavage plane. The postoperative courses were uneventful. Both the histological examinations were oriented towards a DDLPS and both patients benefited from adjuvant chemotherapy. In conclusion, the treatment of giant RPS is still challenging and requires multidisciplinary treatment as well as, when possible, radical surgical removal. The lack of tissue infiltration and the avoidance of excision or reconstruction of major organs (including the kidney) could lead to an easier postoperative course and an improved prognosis. When possible, surgical management of recurrences or incompletely resected masses must be pursued. Since the COVID pandemic caused limited medicalization of a number of population groups and delayed diagnosis of other oncologic diseases, an increased number of DDLPSs could be expected in the near future

    Ethical Issues in the Use of Suboptimal Kidneys for Transplants: an Italian Point of View

    Get PDF
    The shortage of organs leads to the need for utilizing suboptimal kidneys for transplantation. The distinction between optimal, marginal, and suboptimal kidneys leads surgeons to face not only technical problems but also ethical and legal issues related to clinical advantages offered by the transplant of a nonstandard kidney and the acquisition of consent. Between 1999 and 2015, we performed 658 transplants, 49 (7.5%) using suboptimal kidneys. All patients were alive and with vital graft throughout follow-up. We did not encounter any major surgical complications. From a technical point of view, our experience and literature review confirm that transplant of suboptimal kidney leads to good clinical results but exposes patients to a increased risks of surgical complications. Therefore, these interventions must take place in hospitals fully prepared for this type of surgery and performed by experienced transplant surgeons with proper matching between organ and recipient. Considering the insufficient resources available, from an ethical and legal point of view, doctors play an essential role in optimizing the use of these kidneys by avoiding wastage of organs, ensuring that transplants are done in suitable patients, and that patients are fully informed and aware of the risks and benefits associated with the specific suboptimal kidney being transplanted. We believe that, in highly specialized centers, the number of suboptimal kidney transplants should be increased, as their use has shown good clinical results and carries fewer ethical issues compared with marginal kidneys. Further, suboptimal kidneys may also be proposed for use in young patients with end-stage renal disease

    Measuring proliferation in breast cancer: practicalities and applications

    Get PDF
    Various methods are available for the measurement of proliferation rates in tumours, including mitotic counts, estimation of the fraction of cells in S-phase of the cell cycle and immunohistochemistry of proliferation-associated antigens. The evidence, advantages and disadvantages for each of these methods along with other novel approaches is reviewed in relation to breast cancer. The potential clinical applications of proliferative indices are discussed, including their use as prognostic indicators and predictors of response to systemic therapy

    The usefulness of lateral internal sphincterotomy combined with hemorrhoidectomy in the treatment of hemorrhoids: a randomized prospective study

    The aim of this prospective randomized study was to investigate anorectal manometric findings in hemorrhoid patients and to evaluate the clinical benefits and physiological consequences of additioning a lateral internal sphincterotomy (LIS) to haemorrhoidectomy. Anorectal manometry was preoperatively performed in forty-eight consecutive patients with prolapsed piles; resting and squeeze pressures, sphincter length and rectoanal inhibitory reflex were recorded. Ten healthy volunteers served as controls. Six patients were excluded because no raised and pressures were found. Forty-two patients were randomised: Group 1 (n = 22) patients underwent haemorrhoidectomy plus LIS; Group 2 (n = 20) patients underwent haemorrhoidectomy alone. Postoperative course was carefully evaluated; all patients were questioned about continence and anorectal manometry was repeated twice. Sphincter anomalies were found in 87.5% of patients. Haemorrhoidectomy alone did not affect anal pressures, which returned into the normal ranges after sphincterotomy. Postoperative course was better in LIS group. Anal stricture was seen in four patients without sphincterotomy; no patients with LIS experienced and incontinence. This study shows that high and pressures are very frequent in hemorrhoid patients; they are not due to hypertensive and cushions and might have a pathogenetic role. Anorectal manometry is very useful to identify patients with raised anal pressures; in these cases additioning a lateral internal sphincterotomy to haemorrhoidectomy seems justified; it significantly improves postoperative course and can be safely performed
