Uterus transplantation (UTx) is currently the only available treatment for absolute uterine factor infertility. More than 90 uterus transplantations have been performed worldwide, mostly from living donors. Living-donor (LD) UTx is a challenging surgical procedure since it poses ethical issues, and it is a high-risk and invasive surgery with higher hysterectomy-related risks compared to conventional hysterectomy. A total of 59 living-donor hysterectomies have been reported in the literature, including 35 performed with a laparotomic approach, 20 with a robotic approach and 4 with a laparoscopic approach. The mean donor age was 45.6 ± 9.1 years, and 22 were unrelated with the recipients, 34 were emotionally related (27 mothers, 5 sisters, 2 mother’s sisters). The mean recipient age was 28.8 ± 4.5 years. Mayer–Rokitansky–Küster–Hauser syndrome was the most common indication for uterus transplant. Robotic living-donor hysterectomy had the longest operative time but resulted in a lower blood loss and postoperative stay compared to laparotomic and laparoscopic approaches. Twenty-nine births from LD-UTx have been reported, four after robotic living-donor hysterectomy and twenty-five after a laparotomic procedure. UTx is now an effective treatment for women with UFI. While living-donor UTx in some cases may be considered an experimental procedure, it offers the extraordinary possibility to give women the opportunity to have a pregnancy. Many efforts should be made to reduce the potential risks for donors, including the use of mini-invasive techniques, and the efficacy of UTx in the recipients, giving the potential harm of immunosuppression in a recipient of a non-life-saving organ.

Background: Kidney transplantation outcomes are correlated to many factors, including the socioeconomics conditions and the educational level. Methods: We evaluated the role of educational level on patient and graft survival in a population of 456 kidney transplant recipients. Patients were divided into two groups on the basis of their pre-transplant educational status: patients with primary education (elementary or middle school, as low education) were compared with patients with a secondary school education (high school or a university degree, as high education). Results: Among the 456 patients considered for this analysis, 161 patients had a low educational status, and 295 had a high educational status. Patients with a low educational status were more rarely employed (66.1% vs. 32.5%, p < 0.001), with a high rate of retired patients compared to high-educational status patients (35.6% vs. 10.6%, p < 0.001). Although the educational status did not influence the graft function, the 1-year (88.1% vs. 96.2%, p = 0.0008), 5-year (77.6% vs. 88.8%, p = 0.001), and 10-year (62.1% vs. 75%, p = 0.003) graft survival rates were significantly lower in patients with low educational status compared with high-educational status patients, respectively. Patient survival at 1-year (94.4% vs. 97.6%, p = 0.073), 5-year (85% vs. 92.5%, p = 0.011), and 10-year (75.7% vs. 83.4%, p = 0.042) follow-up was significantly lower in patients with low educational status. Conclusions: Low socioeconomic conditions and educational level had a negative impact on kidney transplant outcomes. Improving access to education and providing targeted educational support and health literacy could enhance treatment adherence and reduce disparities in transplant outcomes.

Background: Kidney transplant recipients (KTRs) experience improved survival and quality of life compared to dialysis treatment, but chronic immunosuppression may increase the risk of de novo post-transplant cancer. Colorectal cancer (CRC) is increasingly recognized in this population. This systematic review aims to synthetize contemporary evidence on CRC epidemiology, outcomes, and risk determinants among KTRs. Methods: A comprehensive search for observational and registry-based studies reporting CRC in adult KTRs was conducted on PubMed, Scopus, Web of Science, and ProQuest. The studies found were subsequently subjected to screening, data extraction, and the risk-of-bias appraisal process. Due to heterogeneity, findings were synthesized narratively. Results: Twenty-six studies encompassing 863,005 KTRs met inclusion criteria: 22 retrospective cohorts, 1 prospective cohort, 2 cross-sectional, and 1 case-control. Absolute CRC occurrence varies by geography, population, and follow-up. Reported risks ranged from no excess to modestly elevated standardized incidence ratios (SIRs): ~0.76–3.60 overall, with a right-sided colon predominance. Overall, higher mortality and worse prognosis were reported in kidney transplant recipients with colorectal cancer compared to the general population, as a result of later-stage diagnosis and more aggressive histologies. Consistent risk factors included older age, time since transplantation, diabetes and metabolic comorbidities, prior dialysis duration/graft failure, and smoking; the female sex showed higher relative CRC risk in some cohorts. The remarkable role of immunosuppression profiles was consistently highlighted: cyclosporine—azathioprine maintenance and alemtuzumab induction were associated with higher CRC risk in large registries, whereas tacrolimus—mycophenolate regimens showed lower risk signals and mTOR inhibitors suggested possible protective effects. Conclusions: Contemporary evidence suggests a modest, heterogenous increase in CRC risk among KTRs, a proximal (right-sided) predominance, and a tendency toward advanced-stage presentation with reduced survival. These findings justify the need to consider risk-tailored, lifelong surveillance strategies anchored in a full colonoscopy, with earlier initiation in younger or otherwise high-risk recipients, alongside careful optimization and periodic re-evaluation of immunosuppression. Prospective multicenter studies and cost-effectiveness analyses should refine screening thresholds and therapeutic strategies. PROSPERO ID: CRD420251071658.

Background: Uterus transplantation (UTx) is currently the only available treatment for absolute uterine factor infertility. Deceased donors have recently emerged as a valid alternative to living donors for uterus transplantation, with similar results. Methods: We report the first experience in Italy of uterus transplantation from deceased donors. Three uterus transplantations from deceased donors were performed at the Organ Transplant Unit of the University Hospital of Catania, Italy, between August 2020 and January 2022. Results: Two patients underwent UTx due to Mayer–Rokitansky–Küster–Hauser syndrome, while one patient had a previous hysterectomy due to benign disease. The donors’ ages were between 25 and 43 years and the mean cold ischemia time was 18.3 h. The mean age of the recipients was 31.6 years, and the mean recipient surgery duration was 5.3 h, with a mean blood loss of 766.66 mL. Two recipients developed a post-transplant hematoma, which was treated conservatively. No uterus recipient needed a re-operation during the first 30 days after transplantation. No histological signs of acute rejection were detected at the cervical biopsies performed at 1, 3, and 6 months after transplantation. First menstruation occurred in all recipients after 39 ± 12 days after transplantation. One live birth was reported 15 months after UTx. One graft was lost three months after UTx due to graft thrombosis. Conclusions: Uterus transplantation from deceased donors is emerging as a valid alternative to living donors in order to increase the donor pool.

Surgical bypass is the gold standard treatment in patients affected by chronic limb-threatening ischemia in advanced GLASS stages, according to the Global Vascular Guidelines. For patients in whom an autologous graft is not available, a prosthesis could be used with the adjunct of a distal arteriovenous fistula interposition. The aim of this study was to examine the long-term results of below-the-knee surgical revascularization using a prosthesis with the distal adjunct mentioned above. From 2010 to 2020, we performed 159 lower limb below-the-knee surgical revascularizations using a prosthesis with the creation of an arteriovenous fistula interposition on the distal anastomosis. The GLASS stage was 3 in 100% of patients. The primary patency rates were as follows: 86.7% at 1 year, 57.2% at 3 years, and 12.6% at 5 years. The graft thrombosis rates were 17.4% at 1 year, 42.1% at 3 years, and 64.5% at 5 years. The amputation-free survival rates were 79% at 1 year, 76% at 3 years, and 64% at 5 years. PTFE prosthetic bypass for below-the-knee arteries using an arteriovenous fistula interposition is a good solution in patients without an autologous conduit. This technique offers reasonable graft patency and limb salvage rates.

Background: Delayed graft function (DGF) is common after kidney transplantation from deceased donors and may significantly affect post-transplant outcomes. This study aimed to evaluate whether an innovative approach, based on the administration of the intravenous prostaglandin analogue iloprost, could be beneficial in reducing the incidence of DGF occurring after kidney transplantation from deceased donors. Methods: This prospective, randomized (1:1), placebo-controlled study enrolled all consecutive patients who received a kidney transplant from a deceased donor from January 2000 to December 2012 and who were treated in the peri-transplant period with the prostaglandin analogue iloprost at 0.27 μg/min through an elastomeric pump (treatment group) or with a placebo (control group). Results: A total of 476 patients were included: DGF was reported in 172 (36.1%) patients in the entire cohort. The multivariate analysis showed that the donor’s age > 70 years (OR 2.50, 95% confidence interval (CI): 1.40–3.05, p < 0.001), cold ischemia time > 24 h (OR 2.60, 95% CI: 1.50–4.51, p < 0.001), the donor’s acute kidney injury (OR 2.71, 95% CI: 1.61–4.52, p = 0.021) and, above all, the recipient’s arterial hypotension (OR 5.06, 95% CI: 2.52–10.1, p < 0.0001) were the strongest risk factors for developing post-transplant DGF. The incidence of DGF was 21.4% in the treatment group and 50.9% in the control group (p < 0.001). Interestingly, among patients who developed DGF, those who received iloprost had a shorter duration of post-transplant DGF (10.5 ± 8.3 vs. 13.4 ± 6.7, days, p = 0.016). Conclusions: This study showed that the use of a continuous infusion of iloprost could safely and effectively reduce the incidence of DGF in recipients of deceased-donor kidneys, allowing a better graft functionality as well as a better graft survival.
