Native Kidney Hydronephrosis Is Associated with Upper Urinary Tract Urothelial Carcinoma in Post-Kidney Transplantation Patients. J Clin Med 2021; 10:jcm10194474. [PMID: 34640492 PMCID: PMC8509333 DOI: 10.3390/jcm10194474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 09/27/2021] [Accepted: 09/27/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Upper urinary tract urothelial carcinoma (UTUC) is the most common malignancy occurring after kidney transplantation (KT) in Taiwan. The aim of this study was to investigate the association between native kidney hydronephrosis and UTUC in post-KT patients. Methods: From 2003 to 2018, we conducted a retrospective cohort study that enrolled 1005 post-KT patients, 67 of whom were subsequently diagnosed with UTUC. We divided patients into two groups based on whether or not they had UTUC. Multivariate analysis and Kaplan-Meier plot were used to evaluate if native kidney hydronephrosis was associated with post-KT UTUC. Results: The total cohort consisted of 612 men (60.9%) and 393 women (39.1%) with a mean age of 48.2 ± 12.0 at KT. The mean follow-up time was 118.6 ± 70.2 months, and mean time from KT to UTUC was 7.53 years. There was a significant gender difference with a female predominance among the UTUC patients (73.1% versus 26.9%, p < 0.001). Native kidney hydronephrosis occurred more frequently in the UTUC group (68.7% versus 4.8%, p < 0.001). Multivariate analysis showed that native kidney hydronephrosis and female gender were significantly associated with UTUC with odds ratios of 35.32 (95% CI, 17.99–69.36; p < 0.001) and 3.37 (95% CI, 1.55–7.29; p = 0.002), respectively. UTUC in the post-KT patients also showed aggressive pathological characteristics and a tendency toward bilateral lesions (41.8%). Conclusions: Native kidney hydronephrosis is significantly associated with post-KT UTUC patients in Taiwan. Native kidney hydronephrosis may be a deciding factor for standard nephroureterectomy and bladder cuff excision in selected patients. Nevertheless, almost half of the patients with kidney hydronephrosis do not present with UTUC at the end of our study.

Abstract
Acute kidney injury (AKI) is a significant risk factor for developing chronic kidney disease and progression to end-stage renal disease in elderly patients. AKI is also a relatively common complication after kidney transplantation (KTx) associated with graft failure. Since the lifespan of a transplanted kidney is limited, the risk of the loss/deterioration of graft function (DoGF) should be estimated to apply the preventive treatment. The collection of saliva and urine is more convenient than collecting blood and can be performed at home. The study aimed to verify whether non-invasive biomarkers, determined in saliva and urine, may be useful in the prediction of DoGF in kidney transplant recipients (KTRs) (n = 92). Salivary and serum toxins (p-cresol sulfate, pCS; indoxyl sulfate, IS) concentrations were determined using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Urinary proteins, hemoglobin, and glucose were measured using a semi-quantitative strip test. Salivary IS (odds ratio (OR) = 1.19), and proteinuria (OR = 3.69) were demonstrated as independent factors for the prediction of DoGF. Satisfactory discriminatory power (area under the receiver operating characteristic curve (AUC) = 0.71 ± 0.07) and calibration of the model were obtained. The model showed that categories of the increasing probability of the risk of DoGF are associated with the decreased risk of graft survival. The non-invasive diagnostic biomarkers are a useful screening tool to identify high-risk patients for DoGF.

Abstract
Renal oncocytoma is an infrequently reported renal neoplasm, often asymptomatic,
which usually behaves as a benign entity and is identified accidentally on
radiological imaging. Transplant patients under long-term immunosuppressive
drugs have a high prevalence of cancers, such as skin cancers,
lymphoproliferative disorders, and renal carcinomas. We present a case report of
an asymptomatic renal oncocytoma in a kidney transplant recipient presenting
persistent hematuria. The features of computed tomography and contrast-enhanced
ultrasound (CEUS) are presented. This was the first time we used CEUS in a
transplant kidney recipient presenting a renal mass, allowing the real-time
visualization of contrast-enhancement patterns during all vascular phases for
the differential diagnosis of renal tumors. Although the pattern of intense
vascularization could mislead to an early judgment as a malignant lesion, it
could help to exclude other renal lesions without inducing nephrotoxicity.

Abstract
BACKGROUND Solid organ transplant recipients have an increased cancer risk owing to immunosuppression and oncogenic viral infections. We report on the incidence and types of bladder cancer in kidney transplant recipients in Ireland, describing possible additional risk factors and outcomes in these patients. METHODS We identified kidney transplant recipients diagnosed with de novo bladder cancer between January 1, 1994, and July 31, 2012, by integrating data from the Irish National Cancer Registry and National Renal Transplant Registry. We calculated the standardized incidence ratio (SIR) and examined patient and tumor characteristics and 1-year survival rate. RESULTS Fifteen patients were diagnosed with de novo bladder cancer during the study period, representing 0.48% of kidney transplant recipients. The SIR was 2.5 (95% CI, 1.4-4.2; P < .001). The mean interval between transplantation and diagnosis of bladder tumor was 8.6 years and mean age at time of diagnosis was 55.7 years. Sixty percent of patients were male. The tumor types were transitional cell carcinoma (9 patients), squamous cell carcinoma (3 patients), adenocarcinoma (1 patient), carcinoma in situ (1 patient), and diffuse large B-cell lymphoma (1 patient). Beside immunosuppression, risk factors associated with bladder cancer were urogenital disease (6 patients), cyclophosphamide exposure (2 patients), BK nephropathy (1 patient), analgesic nephropathy (1 patient), and extensive smoking (1 patient). Eight patients underwent radical cystectomy for invasive tumors, with resection of other pelvic organs in 7 patients. Mortality rate within the first year was 40%. CONCLUSION Bladder cancer occurred more commonly in kidney transplant recipients with a predominance of aggressive tumors and a high mortality. In patients with preexisting risk factors such as urologic abnormalities and cyclophosphamide exposure careful assessment before transplantation and vigilant monitoring posttransplantation with a low threshold for cystoscopy may improve outcomes.

Abstract
In the contemporary era of potent immunosuppressive regimens, previously encountered signs of renal allograft rejection such as fever and hematuria are rarely encountered. We report a teenager with severe recurrent acute humoral and cellular rejection whose presenting feature was gross hematuria with the presence of blood clots in the urine. We want to highlight that severe rejection even in the setting of modern immunosuppressive drugs can present as gross hematuria. Contrary to conventional wisdom that gross hematuria with the presence of blood clots in the urine is indicative of pathology in the renal collecting system, a parenchymal disease process should also be considered in renal transplant recipients.

Hydronephrotic urine in the obstructed kidney promotes urothelial carcinoma cell proliferation, migration, invasion through the activation of mTORC2-AKT and ERK signaling pathways. PLoS One 2013; 8:e74300.

Abstract
Obstructive nephropathy is the most common presentation of urothelial carcinoma. The role of the urine in the obstructed kidney namely "hydronephrotic urine" in urothelial carcinoma has not been extensively explored. This study aims to evaluate whether hydronephrotic urine in the obstructed kidney could promote urothelial carcinoma. The hydronephrotic urine was collected from the obstructed kidneys of Sprague-Dawley rats induced by different periods of unilateral ureteral obstruction (UUO). By the inhibition of LY294002 and PD184352, we confirm that hydronephrotic urine promotes urothelial carcinoma cell (T24) and immortalized normal urothelial cells (E6) proliferation, migration and invasion in a dose-dependent manner through the activation of the mTORC2-AKT and ERK signaling pathways. Hydronephrotic urine also increases the expression of cyclin-D2, cyclin-B and CDK2. It also decreases the expression of p27 and p21 in both urothelial carcinoma cells and normal urothelial cells. By the protein array study, we demonstrate that many growth factors which promote tumor cell survival and metastasis are over-expressed in a time-dependent manner in the hydronephrotic urine, including beta-FGF, IFN-γ, PDGF-BB, PIGF, TGF-β, VEGF-A, VEGF-D and EGF. These results suggest that hydronephrotic urine promotes normal and malignant urothelial cells proliferation, migration and invasion, through the activation of the mTORC2-AKT and ERK signaling pathways. Further investigation using live animal models of tumor growth may be needed to clarify aspects of these statements.

Distinguishing characteristics of urothelial carcinoma in kidney transplant recipients between China and Western countries. Transplant Proc 2013; 45:2197-202. [PMID: 23747184 DOI: 10.1016/j.transproceed.2012.10.035] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2012] [Accepted: 10/09/2012] [Indexed: 01/20/2023]
Abstract
OBJECTIVE To identify significant distinctive characteristics of urothelial carcinoma (UC) in kidney transplant recipients between China and Western countries and investigate probable tumor screening and treatment factors contributing to these differences. METHODS Renal transplant recipients from 1998 to 2011 in our institution diagnosed with UC were included in this study. Our data on tumor incidence, clinical characteristics, and outcomes were compared with literature reports. RESULTS Among 2572 renal transplant recipients identified, 24 (0.93%) experienced UC, including 10 men and 14 women of overall mean age of 49.3 ± 11.6 years at transplantation and 53.5 ± 9.5 years at tumor detection. The Chinese traditional herbal intake mainly focused on 2 preparations: Aristolochic acid and rhubarb (the latter was mainly used in patients with chronic renal impairment) in 20 people. There were 21 (87.5%) cases of upper (UTUC) 5 cases of bilateral, and 13 cases of multifocal urinary tract urothelial carcinoma. Four subjects died owing to tumor progression at 4-63 months postoperatively. CONCLUSIONS UC in renal transplant recipients shared notable characteristics in China with widespread herb intake: UTUC predominance; multifocal and bilateral organ involvement; high rates of recurrence, progression, and dissemination, in contrast with bladder tumor dominance in Western countries. As a consequence, we suggest that bilateral nephroureterectomy should be performed prophylactically in high-risk patients, especially those with a long history of Chinese herb intake. The relationship of rhubarb consumption to UC in renal transplant recipients should be noted and evaluated.
