OBJECTIVES
Haematuria is a common indication for a urology evaluation. In many cases, its cause is not determined unequivocally, but it does not pose any threat to the patient. However, it can represent the first symptom of urinary tract cancer.
BACKGROUND
The present study aimed to compare the risk of urological malignancies in patients with haematuria who received antiplatelet or anticoagulant therapy versus those who did not.
METHODS
This prospective study included 562 patients with haematuria during the period of 2018‒2021. Among these, 129 patients had macroscopic haematuria. All patients underwent a urinary tract ultrasound, CT with urography, and cystoscopy. Patients with suspected malignancy underwent an appropriate surgical procedure with a pathology examination. Data were analysed with univariate and multiple logistic regression.
RESULTS
The incidence rates of malignancies were 21.5 % overall, and 44.2 % and 14.8 % among patients with macroscopic and microscopic haematuria, respectively. Univariate regression showed that the odds of malignancy was significantly higher among patients with antiplatelet therapy compared to patients without antiplatelet therapy (OR: 1.88, 95% CI: 1.14‒3.05). In contrast, anticoagulation therapy did not significantly increase the odds of malignancy compared to no anticoagulation therapy (OR: 1.45, 95% CI: 0.74‒2.69). However, a multiple logistic regression model that included other known risk factors (e.g., sex or age) showed similar odds of malignancy among these patient groups.
CONCLUSIONS
Malignancy risk for patients who received anticoagulant or antiplatelet therapy was similar to the risk observed in the general population. Antiplatelet and anticoagulant therapy were not significant risk factors of urological malignancy in patients with haematuria. The results from the present study will be used in a power analysis for an upcoming multicentre study (Tab. 4, Ref. 17).

BACKGROUND
Urothelial carcinoma recurrence of an orthotopic neobladder created from bowel segment is a rare occurrence. The usage of bowel segments to create neobladder following cystectomy for urinary diversion is growing yet there still remains a large gap in the literature about recurrence in neobladder. We carry out the first systematic review to outline current details of urothelial cancer recurrences in a neobladder, diagnostic approach, management and long term prognosis.
METHOD
We carried out a systematic review searching databases PubMed (MEDLINE), Scopus and Web of Science. Only studies reporting on urothelial carcinoma recurrence of the neobladder with or without multi-focal disease were reported. A quality assessment tool was utilized to ensure all studies met quality standards.
RESULTS
Fifteen studies were included in the systematic review meeting inclusion criteria. Fourteen of these studies were cases in men where pT3 disease was the most prevalent (29%). The most common symptomology was macroscopic haematuria seen in eight patients (53.33%). Management varied among cases and including adjuvant chemotherapy regimens and surgical interventions consisting of endoscopic resection to robotic neocystectomy and nephroureterectomy. Follow up period for these patients was up to 38 months and 55% of patients did not see a recurrence.
CONCLUSION
The nature of recurrence is hypothesised to be due to seeding of urothelial cells into the non-urothelial surfaces compatible for both implantation and growth. We present the first systematic review to report on recurrence rates and details of diagnosis and outcomes of various management regimes for urothelial carcinoma of the neobladder.

BACKGROUND
Tubulointerstitial lesions and glomerular inflammation severity have been shown to correlate with proteinuria in children with IgA nephropathy (cIgAN). However, there is a lack of data regarding severity of histopathologic findings in cIgAN in patients with minimal to absent proteinuria since kidney biopsy indications are not well defined in these cases.
METHODS
Twenty-eight cIgAN patients with kidney biopsy from 4 different centers in Paris (France) and Montreal (Canada) with a urine protein/creatinine ratio (UPCr) ≤ 0.03 g/mmol and a normal estimated glomerular filtration rate (eGFR > 90 ml/min/1.73 m) on the day of kidney biopsy prior to treatment were included.
RESULTS
Median age was 11.82 (9.32-13.45) years, and median follow-up was 4 years (2.87-6.53). At time of biopsy, median eGFR was 116 (102.3-139.7) ml/min/1.73 m, and median UPCr was 0.02 (0.011-0.03) g/mmol. Microscopic or macroscopic hematuria was present in 35.7% and 64.3% of cases, respectively. Kidney biopsy microscopy analysis showed mesangial (M1), endocapillary (E1), or extracapillary (C1) hypercellularity in 53.5%, 32.1%, and 7.1% of patients, respectively. Chronic histological lesions were also present: glomerulosclerosis (S1) in 42.8% and tubular atrophy/interstitial fibrosis in 7.1%. Podocytopathic features were detected in 21.4%. An ACE inhibitor or immunosuppressive therapy (IS) was prescribed in 42.8% and 21.4% of these patients respectively. One-third (35.7%) received no treatment. At last follow-up, median eGFR was 111.9 (90.47-136.1) ml/min/1.73 m, and median UPCr was 0.028 (0.01-0.03) g/mmol.
CONCLUSION
cIgAN with minimal proteinuria at time of biopsy might be linked with acute and chronic glomerular lesions.

The association between Klippel-Trenauney syndrome (KTS) and bladder hemangiomas is rare. The most common clinical manifestation is hematuria. The diagnosis is made from the characteristic cystoscopic appearance of the tumor. We report the case of a patient presenting recurrent macroscopic hematuria in the context of KTS. A cystoscopic evaluation revealed bladder hemangiomas. A conservative approach consisting of bladder irrigation and close follow-up was chosen as therapy. Conservative treatment of bladder irrigation and close follow-up is the recommended initial treatment of moderate and infrequent episodes of hematuria in this context. The more invasive therapeutic options have to be considered especially for frequent or life-threatening episodes of hematuria. This case suggests that conservative treatment may be effective in treating moderate and infrequent episodes of hematuria due to bladder hemangioma in the context of KTS. Further studies are required to adequately establish the effectiveness, limitations, and complications of each approach.

Review
The Diagnostic Accuracy of Cystoscopy for Detecting Bladder Cancer in Adults Presenting with Haematuria: A Systematic Review from the European Association of Urology Guidelines Office.
CONTEXT
Haematuria can be macroscopic (visible haematuria [VH]) or microscopic (nonvisible haematuria [NVH]), and may be caused by a number of underlying aetiologies. Currently, in case of haematuria, cystoscopy is the standard diagnostic tool to screen the entire bladder for malignancy.
OBJECTIVE
The objective of this systematic review is to determine the diagnostic test accuracy of cystoscopy (compared with other tests, eg, computed tomography, urine biomarkers, and urine cytology) for detecting bladder cancer in adults.
EVIDENCE ACQUISITION
A systematic review of the literature was performed according to the Cochrane Handbook for Systematic Reviews of Diagnostic Test Accuracy and Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) extension for diagnostic test accuracy studies' checklist. The MEDLINE, Embase, Cochrane CENTRAL, and Cochrane CDSR databases (via Ovid) were searched up to July 13, 2022. The population comprises patients presenting with either VH or NVH, without previous urological cancers. Two reviewers independently screened all articles, searched reference lists of retrieved articles, and performed data extraction. The risk of bias was assessed using Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2).
EVIDENCE SYNTHESIS
Overall, nine studies were included in the qualitative analysis. Seven out of nine included trials covered the use of cystoscopy in comparison with radiological imaging. Overall, sensitivity of cystoscopy ranged from 87% to 100%, specificity from 64% to 100%, positive predictive value from 79% to 98%, and negative predictive values between 98% and 100%. Two trials compared enhanced or air cystoscopy versus conventional cystoscopy. Overall sensitivity of conventional white light cystoscopy ranged from 47% to 100% and specificity from 93.4% to 100%.
CONCLUSIONS
The true accuracy of cystoscopy for the detection of bladder cancer within the context of haematuria has not been studied extensively, resulting in inconsistent data regarding its performance for patients with haematuria. In comparison with imaging modalities, a few trials have prospectively assessed the diagnostic performance of cystoscopy, confirming very high accuracy for cystoscopy, exceeding the diagnostic value of any other imaging test.
PATIENT SUMMARY
Evidence of tests for detecting bladder cancer in adults presenting with haematuria (blood in urine) was reviewed. The most common test used was cystoscopy, which remains the current standard for diagnosing bladder cancer.

Renal cell carcinoma (RCC) is the most common type of kidney cancer. It typically presents with macroscopic hematuria, weight loss, and or a palpable flank mass. Diagnosis of this disease involves imaging techniques such as abdominal ultrasound and CT scans. Care for RCC can consist of ablation, tumor removal, nephrectomy, and systemic treatment options. Herein, we present a case of a 50-year-old Hispanic male with complaints of rectal bleeding and hematuria. Prior to admission, the patient had been informed twice about high suspicion of renal malignancy. Due to low health literacy and barriers to communication, he failed to understand the magnitude of his diagnosis. Subsequently, he underwent a resection of a considerable 22 cm x 13 cm x 13 cm RCC of his left kidney. This case highlights the need for effective patient health education to prevent emotional distress in patients with low health literacy.

Paraganglioma of the urinary bladder is an exceptionally rare tumor. It originates from chromaffin cells, which are responsible for producing catecholamines. We report a unique case of a 74-year-old woman diagnosed with nonfunctional bladder paraganglioma, who presented with macroscopic hematuria and right-sided renal colic but lacked the usual symptoms associated with catecholamine excess. This case highlights the diagnostic challenges of nonfunctional variants of paraganglioma due to their histological similarity to urothelial carcinomas. It underscores the importance of a thorough histological examination and the need for a multidisciplinary approach to establish a diagnosis and determine the optimal treatment strategy. Our case contributes to the sparse literature on this rare condition, and it aims to enhance clinicians' awareness and understanding of urinary bladder paragangliomas.

Acute immune thrombocytopenic purpura (ITP) has been revealed as an uncommon complication of COVID-19 in children. Severe bleeding may occur but is rarely life threatening. Management is based on the severity of bleeding symptoms and the degree of thrombocytopenia. We report the case of a 7-year-old girl with severe acute ITP secondary to a COVID-19 infection -without any respiratory symptoms. The initial clinical examination showed a large bulging mediodorsal hematoma, purpuric lesions, and posterior pharyngeal hemorrhage. The patient was monitored in a pediatric intensive care unit. Initial medical management consisted of intravenous immunoglobulins and systemic steroids. Despite this treatment, bleeding and thrombocytopenia worsened, and secondary macroscopic haematuria occurred, requiring 6-hourly platelet transfusions and increased steroid doses to obtain sufficient hemostasis. This case presents a rare and severe acute pediatric ITP secondary to asymptomatic SARS-COV2 which was refractory to initial management and opens the discussion to second line therapeutic interventions.

A 75-year-old man presented with macroscopic hematuria and a high serum prostate-specific antigen (PSA) level. Macroscopic hematuria had subsided by the time of consultation. The PSA level was 38.590 ng/ml, which, along with rectal examination and magnetic resonance imaging findings, led to the suspicion of prostate cancer. Transrectal needle biopsy of the prostate revealed intraductal carcinoma of the prostate (IDC-P). Computed tomography and bone scintigraphy were performed, and the prostate cancer was classified as cT2cN0M0. After 6 months of combined androgen blockade therapy, a radical prostatectomy was performed; however, PSA levels continued to increase, and the patient was diagnosed with castration resistant prostate cancer. Multiple bone metastases appeared 5 months after the initiation of abiraterone therapy. Three courses of docetaxel and two courses of cabazitaxel were administered, but the disease progression continued. The IDC-P was found to be positive for the BRCA2 mutation by BRACAnalysis® performed at the start of cabazitaxel therapy. To our knowledge, no other cases of BRCA2 mutation positive IDC-P have been reported in Japan. After we started administration of Olaparib, the patient's PSA level was lowered and the disease progression stopped.

INTRODUCTION
Macroscopic hematuria (MH) bouts, frequently accompanied by acute kidney injury (AKI-MH) are one of the most common presentations of IgA nephropathy (IgAN) in the elderly. Immunosuppressive therapies are used in clinical practice; however, no studies have analyzed their efficacy on kidney outcomes.
METHODS
This is a retrospective, multicenter study of a cohort of patients aged ≥50 years with biopsy-proven IgAN presenting with AKI-MH. Outcomes were complete, partial, or no recovery of kidney function at 1 year after AKI-MH, and kidney survival at 1, 2, and 5 years. Propensity score matching (PSM) analysis was applied to balance baseline differences between patients treated with immunosuppression and those not treated with immunosuppression.
RESULTS
The study group consisted of 91 patients with a mean age of 65 ± 15 years, with a mean follow-up of 59 ± 36 months. Intratubular red blood cell (RBC) casts and acute tubular necrosis were found in all kidney biopsies. The frequency of endocapillary hypercellularity and crescents were low. Immunosuppressive therapies (corticosteroids alone or combined with mycophenolate mofetil or cyclophosphamide) were prescribed in 52 (57%) patients, whereas 39 (43%) received conservative treatment. There were no significant differences in the proportion of patients with complete, partial, or no recovery of kidney function at 1 year between patients treated with immunosuppression and those not treated with immunosuppression (29% vs. 36%, 30.8% vs. 20.5% and 40.4 % vs. 43.6%, respectively). Kidney survival at 1, 3, and 5 years was similar among treated and untreated patients (85% vs. 81%, 77% vs. 76% and 72% vs. 66%, respectively). Despite the PSM analysis, no significant differences were observed in kidney survival between the two groups. Fourteen patients (27%) treated with immunosuppression had serious adverse events.
CONCLUSIONS
Immunosuppressive treatments do not modify the unfavorable prognosis of patients with IgAN who are aged ≥50 years presenting with AKI-MH, and are frequently associated with severe complications.
