RESUMEN

Herein, we describe our surgical technique and outcome of a kidney transplant in a patient with failing vascular access. A right donor kidney was transplanted into the right iliac fossa with an end-to-side arterial anastomosis to the ipsilateral right common iliac artery and end-to-side venous anastomosis to the contralateral left common iliac vein. The possibility of performing an ipsilateral arterial and contralateral venous anastomosis has been shown here to be successful. No post-operative surgical complications were encountered.

RESUMEN

INTRODUCTION: There is a lack of data regarding the peri-operative and long-term outcomes of kidney transplantation in cystic fibrosis (CF) patients. Herein, we report the peri-operative and long-term outcomes of kidney transplantation in CF patients. MATERIALS AND METHODS: All CF patients who received a kidney transplant at the national kidney transplant center between 1993 and 2022 were identified. Recipients of the contralateral donor kidney were selected as a control group. Primary outcomes included 1-, 5-, and 10- year death-censored graft survival and overall survival. Secondary outcomes included peri-operative morbidity, acute graft rejection, delayed graft function (DGF), and length of stay (LOS). RESULTS: Fourteen patients received a kidney transplant over the study period. Median age at transplantation was 35 (IQR 31, 40) years. The 1-, 5-, and 10-year death-censored graft survival was 92, 74, and 74% in the CF group compared to 100, 92, and 92% in the control group (p = .44). The 1-, 5-, and 10-year overall survival in the CF group was 85, 66, and 57% compared to 100, 92, and 82% in the control group (p = .036). There was no significant difference in peri-operative outcomes including LOS (10 vs. 11 days, p = .84), ICU admission (1 vs. 0 patients, p > .99), acute rejection episodes (2 vs. 1 patients, p > .99), and DGF (1 vs. 2 patients, p = .60). CONCLUSION: CF patients have good long-term graft survival, however, overall survival was worse compared to a matched cohort. These data provide important information for transplant surgeons when considering suitable donor allografts in this unique patient population.

RESUMEN

BACKGROUND: This study aims to evaluate allograft and patient outcomes among recipients of kidney transplants after non-renal solid organ transplants. We also aim to compare our findings with recipients of a repeat kidney transplant. METHODS: We performed an analysis on kidney transplant recipients who underwent kidney transplantation after a non-renal solid organ transplant. Survival data were stratified into 2 groups: Group A (n = 37) consisted of recipients of a kidney transplant after prior non-renal solid organ transplant, and Group B (n = 330) consisted of recipients of a repeat kidney transplant. RESULTS: The 1-,5-, and 10-year graft survival (death-censored) for recipients of a kidney transplant post-non-renal solid organ transplant (Group A) were 97.3%, 91.5%, and 86.9%, compared with 97.9%, 90.2%, and 83.4% for recipients of a repeat kidney transplant (Group B) (p = .32). The 1-, 5-, and 10-year patient survival rates were 97.3%, 82.7%, and 79.1% in Group A compared to 97.9%, 90.2%, and 83.4% in Group B. Unadjusted overall patient survival was significantly lower for Group A (p = .017). CONCLUSION: Kidney transplant recipients who have undergone a previous non-renal solid organ transplant have similar allograft survival outcomes, but higher long-term mortality rates compared to repeat kidney transplant recipients.

RESUMEN

INTRODUCTION: Few studies investigate significant perioperative predictors for long-term renal allograft survival after second kidney transplant (SKT). We compared long-term survival following SKT with primary kidney transplant and determined predictors of renal allograft failure after SKT. METHODS: Outcomes of all primary or second kidney transplant recipients at a national kidney transplant center between 1993 and 2017 were reviewed. The primary outcomes measurements were renal allograft survival for both first and second kidney transplants. Secondary outcome measurements were incidence of delayed graft function (DGF), incidence of acute rejection (AR), and predictors for renal allograft survival in SKT recipients. RESULTS: In total, there were 392 SKTs and 2748 primary kidney transplants performed between 1993 and 2017. The 1-, 5-, and 10-year death-censored graft survival for deceased-donor recipients was 95.3%, 88.7%, and 78.2% for primary kidney transplant and 94.9%, 87.1%, and 74.9% for SKT (P = .0288). Survival of primary renal allograft <6 years (HR 0.6, P = .017), AR episodes (HR 1.6, P = .031), DGF (HR 2.0, P = .005), and HLA-DR MM (HR 1.7, P = .018) was independent predictors of long-term renal allograft failure after SKT. CONCLUSION: These findings may provide important information on long-term survival outcomes after SKT and for identifying patients at risk for long-term renal allograft failure after SKT.

RESUMEN

It is often quoted that while short-term graft survival in kidney transplantation has improved in recent years, it has not translated into a commensurate improvement in long-term graft survival. We considered whether this was true of the entire experience of the national kidney transplant program in Ireland. A retrospective analysis of the National Kidney Transplant Service (NKTS) database was undertaken to investigate patient and graft survival for all adult first deceased donor kidney transplant recipients in Ireland, 1971-2015. Three thousand two hundred and sixty recipients were included in this study. Kaplan-Meier methods were used to estimate survival at each time period post transplant for the various eras of transplantation. Uncensored graft survival has improved over the course of the program in Ireland at various time points despite risk factors for graft failure progressively increasing over successive eras. For example the graft survival at 15 years post transplant has increased from 10% in 1971-1975 to 45% by 1996-2000. Ireland has experienced a progressive improvement in long-term graft survival following kidney transplantation. Whether these trends are attributable to biological or nonbiological factors is unclear but likely involves a combination of both.

RESUMEN

INTRODUCTION: The incidence of amputation after simultaneous pancreas and kidney (SPK) transplantation ranges from 9.5% to 23% after 5 years of follow-up. The objective of this study was to investigate the incidence and risk factors for amputation in SPK transplant patients compared to kidney transplantation alone (KTA) after a minimum follow-up of 10 years. METHODS: An analysis was performed on a prospectively maintained database of 81 SPK transplants and 43 KTA consecutively performed in one center for insulin-dependent diabetes mellitus between December 1992 and January 2006. Primary outcome variables were incidence of amputation per patient, total number of amputations, and type of amputation performed. Data are presented as a mean ± standard deviation. RESULTS: Seven patients (9%) in the SPK cohort and one patient (2%) in the KTA cohort underwent amputation (P<.001). One amputee had pancreas allograft failure prior to amputation. Fifteen amputations were performed in total and four patients required ≥2 amputations. The latency period between transplantation and amputation was 133.57±49.43 months in the SPK cohort and 168 months in the KTA group. CONCLUSIONS: The incidence of amputation after SPK transplantation is approximately 9% after 10-year follow-up. Patients are at a significantly greater risk of amputation after SPK transplantation compared to KTA for type 1 diabetes despite insulin independence.

RESUMEN

Renal transplant recipients are at an increased risk of developing Methicillin-resistant Staphylococcus aureus due to their immunosuppressed status. Herein, we investigate the incidence of MRSA infection in patients undergoing renal transplantation and determine the effect of MRSA colonisation on renal allograft function and overall mortality. Between January 1st 2007 and December 31st 2012, 1499 consecutive kidney transplants performed in our transplant unit and a retrospective 1:2 matched case-control study was performed on this patient cohort. The 1-, 3- and 5-year overall graft survival rates were 100%, 86% and 78%, respectively, in MRSA positive recipients compared with 100%, 100% and 93%, respectively, in the control group (P < 0.05). The 1-, 3- and 5-year overall patient survival rates were 100%, 97% and 79%, respectively, in MRSA positive recipients compared with 100%, 100% and 95%, respectively, in the control group (P = 0.1). In a multiple logistic regression analysis, colonisation with MRSA pre-operatively was an independent predictor for renal allograft failure at 5 years (hazard ratio: 4.6, 95% confidence interval: 1-30.7, P = 0.048). These findings demonstrate that the incidence of long-term renal allograft failure is significantly greater in this patient cohort compared with a matched control population.

RESUMEN

Transplantation of renal allografts with anatomic variability or injured vasculature poses a challenge to the transplanting surgeon but can be salvaged for transplantation with ex vivo bench reconstruction of the vasculature. We investigated whether renal allograft function is impaired in these reconstructed allografts; compared to the donor-matched, un-reconstructed allograft. Reconstructed allografts were transplanted into 60 patients at our institution between 1986 and 2012. A control group was selected from the matched pair of the recipient in deceased donor transplantation. We found no significant difference in the overall graft and patient survival rates (P = 1.0, P = 0.178). Serum creatinine levels were not significantly higher in the study group at 1, 3 and 12 months postoperatively. There were two cases of vascular thrombosis in the study group that were not related to the ex vivo reconstruction. A significantly greater proportion of reconstructed patients were investigated with a colour duplex ultrasound postoperatively (0.007). Although we have demonstrated a higher index of suspicion of transplant failure in patients with a reconstructed allograft, this practice has proven to be a safe and useful technique with equivocal outcome when compared to normal grafts; increasing the organ pool available for transplantation.

RESUMEN

INTRODUCTION AND IMPORTANCE: Renal transplant recipients have a higher risk for developing cancers compared to the general population due to high-dose immunosuppression. The risk of renal cell carcinoma (RCC) in native kidneys is 7-fold greater than the general population and development of RCC in an allograft kidney is extremely rare. We report the diagnosis and management of a large RCC in an allograft renal transplant and metastatic disease in a regional lymph node. CASE PRESENTATION: A 46 year old male patient with a history of simultaneous pancreas and kidney transplant presented with visible haematuria. His pancreas allograft continued to function well however following severe BK nephritis his renal transplant failed. A CT urogram demonstrated a 6 cm contrast enhancing mass in the failed renal transplant and an enlarged pelvic lymph node. He underwent a transplant nephrectomy with excision of the metastatic lymph node deposit. CLINICAL DISCUSSION: We report the diagnosis and management of a large RCC in an allograft renal transplant and metastatic disease in a regional lymph node. There is currently no guidelines on the management of allograft RCC. CONCLUSION: Our case report shows that surgical excision of a large RCC in an allograft renal transplant is possible.

RESUMEN

BACKGROUND: Approximately 1 in 5 patients with autosomal dominant polycystic kidney disease (ADPKD) will undergo a native nephrectomy in their lifetime. These can be emergent or planned and the indications can range from space for kidney transplant, pain, hematuria and frequent urinary tract infections (UTIs). Due to the diverse nature of presentations, there is a lack of certainty about outcomes and optimal management. AIMS: This study aimed to evaluate preoperative indications and perioperative/postoperative complications in this patient cohort. METHODS: This retrospective review included 41 patients with ADPKD who underwent unilateral or bilateral nephrectomy in a single hospital between 2010 and 2020. We collected data on patient demographics, surgical indications, histological results and postoperative complications. We sourced this information using the hospital's patient medical records. RESULTS: The main indications for nephrectomy were pain (39.5%) and bleeding (41.8%). Further indications included recurrent UTIs (16.3%), space for transplantation (27.9%), query malignancy (4.7%) and compressive gastropathy (2.3%). With regard to side, 55.8% were right-sided, 23.3% were left-sided, and 20.9% were bilateral. Seven percent of nephrectomy specimens demonstrated malignancy. Postoperative morbidity included requiring blood transfusion and long hospital stay. Thirty-seven percent of patients received a postoperative blood transfusion. There was no immediate or postoperative mortality associated with any of the cases reviewed. CONCLUSIONS: In conclusion, this study demonstrates that native nephrectomy remains a safe operation for patients with ADPKD. Although further research is needed into, transfusion protocols, adjunctive therapies, such as TAE and research into timing of nephrectomy are still needed.

RESUMEN

BACKGROUND: Penile fractures are uncommon urological emergencies which occur when there has been a breach in the tunica albuginea of the corpora cavernosum that may be unilateral and bilateral and can extend to involve the urethra. AIM: To assess the management and outcomes of penile fractures in a single institution in Ireland. METHODS: A retrospective review of the emergency theatre logbooks was performed between 2011 and 2021 to identify patients who had undergone an exploration for a suspected penile fracture. OUTCOMES: Seventeen patients were initially identified on review of theatre logbooks as having an exploration for a suspected penile fracture. Two patients were excluded from the study due to a lack of clinical notes being available. A further 4 patients on chart review were found to not have a penile fracture at exploration. RESULTS: Eleven patients had a confirmed penile fracture intra-operatively, four of whom had an associated urethral injury. Nine (9/11) patients had preserved normal erections post-operatively documented on follow-up; two, however, reported erectile dysfunction requiring phosphodiesterase inhibitors. CLINICAL IMPLICATIONS: Our study supports urgent surgical exploration for penile fractures to ensure good functional outcomes. STRENGTHS AND LIMITATIONS: This is a retrospective review of theatre logbooks to identify patients with a suspected penile fracture. CONCLUSION: The results of our cohort show a good outcome of erectile function following surgical repair of a penile fracture (9/11; 82%). Four patients (4/11; 36%) had a urethral injury diagnosed intra-operatively, one of whom required a formal urethroplasty.

RESUMEN

BACKGROUND: We assess our long-term experience with regards the safety and efficacy of Mycophenolate Mofetil (MMF) in our low risk renal transplant population and compared it retrospectively to Azathioprine (AZA) immunosuppressive regimen. Patients and methods. Between January 1999 and December 2005, 240 renal transplants received MMF as part of their immunosuppressive protocol (MMF group). AZA group of 135 renal transplants was included for comparative analysis (AZA group). Patients received Cyclosporine was excluded from this study. RESULTS: The incidence of biopsy proven 3-month acute rejections was 30 (12.5%) in MMF group and 22 (16%) in AZA group respectively (P = 0.307). Patient survival rates at 1 and 5 years for the MMF group were 97 and 94%, respectively, compared to 100% and 91% at 1 and 5 years respectively for the AZA group (P = 0.61). Graft survival rates at 1 and 5 years for the MMF group were 95 and 83%, respectively, compared to 97 and 84% at 1 and 5 years, respectively for the AZA group (P = 0.62). CONCLUSION: There was no difference in acute rejection episodes between MMF and AZA based immunotherapy. Additionally, we observed no significant difference concerning graft survival in the MMF group when compared to AZA group.

RESUMEN

We assessed our long-term experience with regards to the safety and efficacy of MMF in our pediatric renal transplant population and compared it retrospectively to our previous non-MMF immunosuppressive regimen. Forty-seven pediatric renal transplants received MMF as part of their immunosuppressive protocol in the period from January 1997 till October 2006 (MMF group). A previously reported non-MMF group of 59 pediatric renal transplants was included for comparative analysis (non-MMF group). The MMF group comprised 29 boys and 18 girls, whereas the non-MMF group comprised 34 boys and 25 girls. Mean age was 11.7 and 12 yr in the MMF and non-MMF groups, respectively. The incidence of acute rejection episodes was 11 (23.4%) and 14 (24%) in the MMF and non-MMF group, respectively. Two (3.3%) grafts were lost in the non-MMF group compared with one (2.1%) in the MMF group. Twenty-one (44.68%) patients in the MMF group developed post-transplant infections compared with 12 (20.33%) in the non-MMF group (p < 0.0001). In conclusion, the use of MMF in pediatric renal transplantation was not associated with a lower rejection rate or immunological graft loss. It did, however, result in a significantly higher rate of viral infections.

RESUMEN

A 58-year-old woman with a prior radical cystectomy and ileal conduit underwent a living-related donor renal transplant for end-stage renal disease secondary to autoimmune glomerulonephritis. She subsequently developed an ischaemic stricture of the transplant ureter. A successful ureteropyelostomy was performed with the native right ureter anastomosed to the pelvis of the renal transplant. She presented to the emergency department 18 months later feeling unwell and with raised inflammatory markers. Imaging demonstrated a large soft tissue mass over the right psoas muscle and hydronephrosis of the native right kidney. A nephrostomy and nephrostogram of the native right kidney diagnosed a urine leak from the native right kidney and she underwent an open right native nephrectomy. She recovered well postoperatively and continues to have excellent graft function. Renal transplantation in an abnormal urinary tract carries a high risk of complications. A multidisciplinary team approach is essential in offering the most appropriate treatment and ensuring good graft function is preserved.

RESUMEN

To report the long-term outcome of deceased donor kidney transplantation in children with emphasis on the use of an intensive initial immunosuppression protocol using R-ATG as antibody induction. Between January 1991 and December 1997, 82 deceased donor kidney transplantations were performed in 75 pediatric recipients. Mean recipient age at transplantation was 12.9 yr and the mean follow-up period was 12.6 yr. All patients received quadruple immunosuppression with steroid, cyclosporine, azathioprine, and antibody induction using R-ATG-Fresenius. Actual one, five, and 10 yr patient survival rates were 99%, 97%, and 94%, respectively; only one patient (1.2%) developed PTLD. Actual one, five, and 10 yr overall graft survival rates were 84%, 71%, and 50%, respectively; there were five cases (6%) of graft thrombosis and the actual immunological graft survival rates were 91%, 78%, and 63% at one, five, and 10 yr, respectively. The use of an intensive initial immunosuppression protocol with R-ATG as antibody induction is safe and effective in pediatric recipients of deceased donor kidneys with excellent immunological graft survival without an increase in PTLD or other neoplasms over a minimum 10-yr follow up.

RESUMEN

INTRODUCTION: Long-term efficacy of treatment with varicocele embolization is poorly documented from the patient's perspective. This study assessed patients' perceived changes in pain scores pre- and post-testicular vein embolization. In addition, the effect of testicular vein embolization on quality of life (QoL) parameters was assessed. METHODS: All patients treated with embolization for varicocele-related orchalgia were analysed (2009-2015). A standardized pain impact questionnaire was used to assess pain scores pre- and post-procedure. The primary outcome was to assess patients' pain relief post-varicocele embolization. The secondary outcome was patients' perceived efficacy of the embolization procedure in terms of improvement in QoL parameters. RESULTS: Sixty patients underwent varicocele embolization due to persistent orchalgia; of which 44 responded to the questionnaire. The mean pre-procedural pain score was 5.4/10 (range of 1.5-9). Post-procedure questionnaire was performed at a median of 58 months (range 28-106 months). At 1, 6 and 12 months post-procedure, the mean pain score was 1.57, 0.55 and 0.3, respectively. 50% (n = 22) reported complete pain relief 1-month post-embolization while 89% (n = 39) of patients reported complete resolution of pain at 1 year. Among the measured QoL parameters; varicocele embolization resulted in significant improvement in return to work, housework, socializing, exercise, sexual relations, and sleeping post-embolization (P < 0.01). CONCLUSION: Varicocele embolization results in a durable reduction in pain scores compared to their pre-operative values. Information from this study will allow clinicians to convey the potential improvements in pain parameters to patients undergoing embolization of symptomatic varicoceles.

RESUMEN

OBJECTIVES: Delayed graft function after kidney transplant can affect patient and graft survival, resulting in prolonged hospital stay and need for dialysis. Ischemia times during organ procurement and reanastomosis at transplant are key factors in delayed graft function. MATERIALS AND METHODS: We analyzed all living- and deceased-donor renal transplants in Ireland over a 33-month period, with effect of warm ischemia time during anastomosis on delayed graft function being the primary outcome. We performed statistical regression analyses to account for confounding variables. Patients had identical surgical technique and immunosuppression protocols. RESULTS: Of 481 transplants during the study period, 20 patients were excluded because of paired-kidney exchange, nephron dosing transplant, or simul-taneous pancreas-kidney transplant. In the donor pool, 70% were donors after brainstem death, 3.6% were donors after cardiac death, and 26% were living donors. All living donors were direct altruistic donors and underwent stringent assessment via the ethics committee and multidisciplinary team meeting. Of living donors, 8% were not related. These were true altruistic donors who were acquaintances of the recipients and volunteered themselves for assessment. They were assessed in accordance with the declaration of Istanbul and received no compensation of any kind for donation. Of total patients, 18% had delayed graft function, defined as need for dialysis within 7 days of transplant. Warm ischemia time during anastomosis significantly affected risk of delayed graft function but not graft survival or function at 3 months. This factor did not correlate with hospital stay duration. Time on dialysis and recipient weight significantly correlated with risk of delayed graft function. CONCLUSIONS: Our findings support a role for minimizing warm ischemia time during anastomosis to reduce delayed graft function and need for dialysis in the perioperative period. However, a longer time does not appear to affect creatinine levels and therefore graft function at 3 months.

RESUMEN

PURPOSE: The critical shortage of kidneys available for transplantation has led to alternate strategies to expand the pool. Transplantation of the 2 kidneys into a single recipient using organs suboptimal for single kidney transplantation was suggested. We assessed results in 24 grafts allocated for dual kidney transplantation vs those in a control group of 44 designated for single kidney transplantation. Each group underwent pretransplant biopsy and recipients were age matched. MATERIALS AND METHODS: Dual kidney transplantation was done in 24 of 1,091 transplants (2.1%) from 2001 to 2008. In patients with dual kidney transplant vs single kidney transplant mean recipient age was 60.6 vs 60.8 years, mean HLA-A, B and DR mismatches were 3.3 vs 2.9, and average patient waiting time was 15.6 vs 13.9 months. All grafts were perfused with University of Wisconsin solution with a mean cold ischemia time of 17.9 hours. On donor dual kidney biopsy in the dual kidney transplant vs single kidney transplant group the average fibrosis rate was 30% (range 25% to 45%) vs 25% (range 3% to 40%) and the glomerulosclerosis rate was 17.9% (range 3.2% to 40.7%) vs 7.1% (range 0% to 50%). RESULTS: Good postoperative renal function was noted in 14 dual kidney transplantation cases. Acute tubular necrosis requiring dialysis developed in 5 patients as well as acute rejection in 1. Two dual kidney recipients (8%) died in the postoperative period with no single kidney deaths. One patient underwent bilateral transplantectomy. Mean anesthesia time was longer in the dual group (371 vs 212 minutes). Patient and graft survival was equivalent to that in the control group at 36 months. CONCLUSIONS: Careful selection of marginal kidneys based on clinical and histological criteria allows the use of organs that would not ordinarily be sufficient for transplantation with acceptable outcomes. This is a valid strategy to address the organ shortage.

RESUMEN

INTRODUCTION: The aim of this study was to determine the cardiovascular (CV) risk factor response in Irish patients with type 1 diabetes following simultaneous pancreas and kidney transplantation (SPK), analyzing response based on mode of immunosuppression and surgical drainage in a uniquely homogenous population. METHODS: A retrospective review of SPKs carried out between 1993 and 2005 in the National Renal and Pancreatic Centre of Ireland was performed. Weight, glycated hemoglobin (HBA1c), lipid profile, and blood pressure (BP) were measured pre- and post-operatively. RESULTS: Fifty-eight SPK patients with functioning grafts were analyzed. Thirty-two were male. Following transplantation, mean HbA1c fell from 8.1 (+/-1.5) to 5.2 (+/-0.5)% (p < 0.0001), total cholesterol from 5.2 (+/-1.2) to 4.5 (+/-1.0) mmol/L (p = 0.0004), serum triglycerides from 1.5 (+/-0.6) to 1.1 (+/-0.6) mmol/L (p < 0.0001), and serum creatinine from 699.3 (+/-273.4) to 162.5 (+/-135.8) mmol/L (p < 0.0001). Systolic and diastolic BP fell from 148.5 (+/-23.3) to 136.9 (+/-22.4) mmHg (p = 0.02), and 84.8 (+/-11.7) to 77.8 (+/-10.4) mmHg (p = 0.003), respectively. Cholesterol reduction was significantly greater in the group that received cyclosporine (n = 29) compared with a tacrolimus and mycophenolic acid mofetil (MMF) combination (1.3 +/- 0.3 vs. 0.2 +/- 0.2 mmol/L, p = 0.003). Choice of exocrine vs. endocrine graft drainage did not affect risk factor response. CONCLUSION: SPK resulted in significant improvements both in glucose control and other measured CV risk factors.

RESUMEN

OBJECTIVES: We reviewed the incidence, management, and survival outcomes of prostate cancer among kidney transplant recipients and compared these characteristics with a national population (nonrecipients). MATERIALS AND METHODS: A retrospective study was performed on all kidney transplant recipients from a National Kidney Transplant Centre who were subsequently diagnosed with prostate cancer. Primary outcome variables included comparisons of incidence and 5-year overall survival in kidney transplant recipients versus nonrecipients after treatment of prostate cancer. Secondary outcome variables were prostate-specific antigen levels at diagnosis, Gleason grade, treatment strategy, and morbidity from treatment among kidney transplant recipients. RESULTS: Of 4048 kidney transplants performed, 3020 were male recipients (63.9%). In total, 34 kidney transplant recipients (1.1%) were diagnosed with prostate cancer 109 ± 83 months (range, 7-372 mo) after transplant. The mean age at prostate cancer diagnosis was 64 ± 7 years, median prostate-specific antigen level was 10 ng/dL (range, 2.6-771 ng/dL), and 76% (n = 26/34) were diagnosed with localized disease. The incidence of prostate cancer was 1126/100 000 in kidney transplant recipients compared with 160/100 000 nonrecipients in Ireland (P = .01). Treatment strategies included curative radiotherapy (n = 18), curative surgery (n = 2), androgen deprivation therapy (n = 8), and watchful waiting (n = 6). Overall survival rates at 1, 3, and 5 years were not significantly different between kidney transplant recipients with prostate cancer versus nonrecipients with prostate cancer (98% vs 98%, 80% vs 79%, and 77% vs 72%, respectively, P = .8). CONCLUSIONS: The incidence of prostate cancer is significantly higher among kidney transplant recipients compared with nonrecipients in the general population, with most diagnosed with localized disease. Definitive management guidelines should be developed to increase awareness and optimize treatment options in this unique patient cohort.
