Epidermoid cyst is an unusual and very rarely described lesion in the kidney. We report the case of a 45-year-old woman with no known pathological history who presented with right flank pain accompanied by macroscopic hematuria. The physical examination was unremarkable. The CT scan evoked a malignant tumor in front of a right renal mass with irregular contours. The patient underwent a total right nephrectomy. The nephrectomy specimen received for pathological examination showed macroscopically an encapsulated cystic mass of 4 cm long axis. The cyst lumen was occupied by solid brownish tissue debris. Histologically, the cystic wall was lined by a keratinizing squamous epithelium with accumulation of keratin lamellae in the cystic lumen. Anatomopathological examination concluded to the diagnosis of renal epidermoid cyst.

Hematuria occurring in patients with acute kidney injury caused by Corona Virus Disease 2019 (COVID-19) infection has been reported. However, cases of macroscopic hematuria in COVID-19 patients leading to a severe decrease in hemoglobin have not been reported heretofore. Herein, we describe the case of a 56-year-old male patient who suffered from spontaneous prostatic hemorrhage caused by thrombocytopenia and coagulation dysfunction associated with COVID-19 infection, which manifested as macroscopic hematuria, bladder blood clot tamponade and severe hemoglobin decline. Prostatic hemorrhage was diagnosed by endoscopy. There was no recurrence of macroscopic hematuria after undergoing transurethral prostate electrocoagulation for hemostasis, infusing plasma to supplement coagulation factors and taking finasteride. One month after the bleeding event, the patient's blood routine reexamination revealed that the platelet count returned to the normal value and coagulation was normal.

OBJECTIVE
Describe the clinical-surgical results of patients with PAS in the low-posterior cervical-trigonal space associated with fibrosis (PAS type 4) compared with PAS types in other locations (Types 1, upper bladder, 2 in upper parametrium) and in particular with PAS type 3, corresponding to dissectible cervical-trigonal invasion. The clinical-surgical results of using a standard hysterectomy were analyzed with a modified subtotal hysterectomy (MSTH) in patients with PAS type 4.
MATERIAL AND METHODS
A descriptive, retrospective, multicenter study included 337 patients of PAS; thirty-two corresponding to PAS type 4, from three PAS reference hospitals, CEMIC, Buenos Aires, Argentina, Fundación Valle de Lili, Cali, Colombia, and Dr. Soetomo General Hospital, Surabaya, Indonesia, between January 2015 and December 2020. PAS was diagnosed by abdominal and transvaginal ultrasound and topographically characterized by ultrafast T2 weighted MRI. In persistent macroscopic hematuria after MSTH, the surgeon performs an intentional cystotomy and uses a square compression suture to achieve the hemostasis inside the bladder wall.According to a PAS topographical classification, the patients with low-vesical cervical involvement compared with PAS located in relation with the upper blader (type1), upper parametrium (type 2 upper), and also with PAS situated in the lower vesical-trigon space (type 3). PAS 3 and 4 are located in identical area, but in type 3, group A, the vesicouterine space was dissectible, and in type 4, group B, significant fibrosis made surgical dissection extremely challenging. Furthermore, group B was divided into patients treated with total hysterectomy (HT) and those treated with a modified subtotal hysterectomy (MSTH). The surgical requirements to perform an MSHT included the availability of proximal vascular control at the aortic level (internal manual aortic compression, aortic endovascular balloon, aortic loop, or aortic cross-clamping). Then surgeon performed an upper segmental hysterotomy, avoiding the abnormal placenta invasion area; after that, the fetus was delivered, and the umbilical cord was ligated.After uterine exteriorization, the surgeon applies a continuous circular suture with number 2 polyglactin 910, taking some portions of the myometrium -to avoid unintentional slipping- around the lower uterine segment and a 3-4 cm proximal to the abnormal adhesion of the placenta. After tightening hard the circular suture, the uterine segment was circumferentially cut, three centimeters proximal to the circular hemostatic sutures. Next, the surgery follows the upper steps of conventional hysterectomy without changes. Additionally, the histological presence of fibrosis was examined in all samples.
RESULTS
Modified subtotal hysterectomy in patients with PAS type 4 (cervical-trigonal fibrosis) resulted in a significant clínico-surgical improvement over total hysterectomy. The median operative time and intraoperative bleeding were 140 min (IQR 90--240) and 1895 mL (IQR 1300-2500) in patients undergoing modified subtotal hysterectomy, and 260 min (IQR 210-287) and 2900 mL (IQR 2150-5500) in patients treated with total hysterectomy, respectively. The complication rate was 20% for MSHT and 82.3% for patients with a total hysterectomy.
CONCLUSIONS
PAS in the cervical trigonal area associated with fibrosis implies a greater risk of complications due to uncontrollable bleeding and organ damage. MSTH is associated with lower morbidity and difficulties in PAS type 4. Prenatal or intrasurgical diagnosis is essential to plan surgical alternatives to improve the results.

INTRODUCTION
Immunoglobulin A1 (IgA1) with galactose-deficient -glycans (Gd-IgA1) play a key role in the pathogenesis of IgA nephropathy (IgAN). Mucosal-tissue infections increase IL-6 production and, in patients with IgAN, are often associated with macroscopic hematuria. IgA1-secreting cell lines derived from the circulation of patients with IgAN, compared to those of healthy controls (HCs), produce more IgA1 that has glycans with terminal or sialylated -acetylgalactosamine (GalNAc). GalNAc residues are added to IgA1 hinge region by some of the 20 GalNAc transferases, the -glycosylation-initiating enzymes. Expression of , encoding GalNAc-T2, the main enzyme initiating IgA1 -glycosylation, is similar in cells derived from patients with IgAN and HCs. In this report, we extend our observations of overexpression in IgA1-producing cell lines from patients with IgAN.
METHODS
expression was analyzed in peripheral blood mononuclear cells (PBMCs) from patients with IgAN and from HCs. Moreover, the effect of overexpression or knock-down on Gd-IgA1 production in Dakiki cells was assessed.
RESULTS
was overexpressed in PBMCs from patients with IgAN. IL-6 increased expression in PBMCs from patients with IgAN and HCs. We used IgA1-producing cell line Dakiki, a previously reported model of Gd-IgA1-producing cells, and showed that overexpression of GalNAc-T14 enhanced galactose deficiency of IgA1, whereas siRNA-mediated GalNAc-T14 knock-down reduced it. GalNAc-T14 was localized in trans-Golgi network, as expected.
CONCLUSIONS
Overexpression of due to inflammatory signals during mucosal infections may contribute to overproduction of Gd-IgA1 in patients with IgAN.

Wunderlich syndrome (WS) is defined as a rare spontaneous renal hemorrhage. It mostly occurs with concomitant diseases without trauma. It usually presents with the Lenk triad and is diagnosed in emergency departments with the effective use of advanced imaging modalities such as ultrasonography, computerized tomography, or magnetic resonance imaging scanning. In the management of WS, conservative treatment, interventional radiology, or surgical procedures are decided according to the patient's condition and treated appropriately. Conservative follow-up and treatment should be considered in patients whose diagnosis is stable. If diagnosed late, the progression can be life-threatening. As an interesting case of WS, a 19-year-old patient was presented with hydronephrosis due to ure-teropelvic junction obstruction. Spontaneous renal hemorrhage without a history of trauma is presented. The patient, who presented to the emergency department with the sudden onset of flank pain, vomiting, and macroscopic hematuria was imaged by computed tomography. The patient could be followed and treated conservatively for the first 3 days, and on the 4th day, his general condition deteriorated, and he underwent selective angioembolization and then laparoscopic nephrectomy. WS is a serious, life-threatening emer-gency, even in young patients with benign conditions. Early diagnosis is mandatory. Delays in diagnosis and non-energetic approaches can lead to life-threatening situations. In hemodynamically unstable non-malignant cases, the decision for immediate treatment, such as angioembolization and surgery, should be taken without hesitation.

BACKGROUND
IgA nephropathy (IgAN) is universally recognized as one of the most common primary glomerular diseases in all ages. Cyclic neutropenia (CN) is a rare haematologic disorder that is associated with mutations of the ELANE gene. The co-occurrence of IgAN and CN is extremely rare. This is the first case report of a patient with IgAN and genetically confirmed CN.
CASE PRESENTATION
We report a case of a 10-year-old boy who presented with recurrent viral upper respiratory tract infections accompanied by several episodes of febrile neutropenia, haematuria, proteinuria and acute kidney injury. Upon first admission, his physical examination was unremarkable. His kidney function was impaired, whereas his urine microscopy showed evidence of macroscopic haematuria and proteinuria. Further workup showed elevated IgA. The renal histology was consistent with mesangial and endocapillary hypercellularity with mild crescentic lesions, while immunofluorescence microscopy showed IgA-positive staining, which was characteristic of IgAN. Moreover, genetic testing confirmed the clinical diagnosis of CN, therefore Granulocyte colony-stimulating factor (G-CSF) was initiated to stabilize the neutrophil count. Regarding proteinuria control, the patient was initially treated with an Angiotensin-converting-enzyme inhibitor for approximately 28 months. However, due to progressive proteinuria (> 1 g/24 h), Corticosteroids (CS) were added for a period of 6 months according to the revised 2021 KDIGO guidelines with favorable outcome.
CONCLUSIONS
Patients with CN are more susceptible to recurrent viral infections, which can trigger IgAN attacks. In our case CS induced remarkable proteinuria remission. The use of G-CSF contributed to the resolution of severe neutropenic episodes, viral infections and concomitant AKI episodes, contributing to better prognosis of IgAN. Further studies are mandatory to determine whether there is a genetical predisposition for IgAN in children with CN.

BACKGROUND
Urogenital cancers are common, accounting for approximately 20% of cancer incidence globally. Cancers belonging to the same organ system often present with similar symptoms, making initial management challenging. In this study, 511 cases of cancer were recorded after the date of consultation among 61,802 randomly selected patients presenting in primary care in six European countries: a subgroup analysis of urogenital cancers was carried out in order to study variation in symptom presentation.
METHODS
Initial data capture was by completion of standardised forms containing closed questions about symptoms recorded during the consultation. The general practitioner (GP) provided follow-up data after diagnosis, based on medical record data made after the consultation. GPs also provided free text comments about the diagnostic procedure for individual patients.
RESULTS
The most common symptoms were mainly associated with one or two specific types of cancer: 'Macroscopic haematuria' with bladder or renal cancer (combined sensitivity 28.3%), 'Increased urinary frequency' with bladder (sensitivity 13.3%) or prostatic (sensitivity 32.1%) cancer, or to uterine body (sensitivity 14.3%) cancer, 'Unexpected genital bleeding' with uterine cancer (cervix, sensitivity 20.0%, uterine body, sensitivity 71.4%). 'Distended abdomen, bloating' had sensitivity 62.5% (based on eight cases of ovarian cancer). In ovarian cancer, increased abdominal circumference and a palpable tumour also were important diagnostic elements. Specificity for 'Macroscopic haematuria' was 99.8% (99.7-99.8). PPV > 3% was noted for 'Macroscopic haematuria' and bladder or renal cancer combined, for bladder cancer in male patients. In males aged 55-74, PPV = 7.1% for 'Macroscopic haematuria' and bladder cancer. Abdominal pain was an infrequent symptom in urogenital cancers.
CONCLUSIONS
Most types of urogenital cancer present with rather specific symptoms. If the GP considers ovarian cancer, increased abdominal circumference should be actively determined. Several cases were clarified through the GP's clinical examination, or laboratory investigations.

Factor XI deficiency (hemophilia C or Rosenthal syndrome) is an inherited rare disorder that leads to abnormal bleeding due to the paucity of the protein named factor XI, which plays a role in the blood clotting cascade. A 42-year-old male was referred to the urology outpatient clinic with macroscopic hematuria. The patient was scheduled for a repeat transurethral resection of a bladder tumor (TURBT). Preoperative coagulation parameters were as follows: the international normalized ratio (INR) was 0.95 (0.85-1.2), the prothrombin time was 10.9 seconds (10-15), and the partial thromboplastin time was 43.7 seconds (21-36). On the second postoperative day, he developed pelvic pain and discomfort. An abdominal CT revealed a 10 cm mass consistent with clot retention. The patient received two units of erythrocyte suspension and six units of fresh frozen plasma to prevent the depletion of hemoglobin and control urinary bleeding. The patient was discharged with a good recovery from the hospital three days after the second surgery. Hematologic disorders are rare but might have fatal consequences following surgery if unnoticed at the earliest stage. Clinicians must consider that patients with a history of unusual bleeding or borderline coagulation parameters might have an underlying hematological disorder and perform a further evaluation.

INTRODUCTION
The aim of this article was to investigate the impact of chronic antithrombotic therapy (AT) use on the time of detection of bladder cancer, assuming that patients taking AT experience episodes of macroscopic hematuria earlier, and therefore have a more favorable histopathological grade and stage, as well as a smaller number and size of tumors compared to patients not taking AT.
MATERIAL AND METHODS
A retrospective, cross-sectional study was conducted, including 247 patients who underwent bladder cancer surgery for the first time at our institution during the three-year period (2019-2021) and who experienced macroscopic hematuria.
RESULTS
A lower frequency of high-grade bladder cancer (40.6% vs 60.1%, P = 0.006), T2 stage (7.2% vs 20.2%, P = 0.014), and a lower frequency of tumors larger than 3.5 cm (29% vs 57.9%, P <0.001) were found in patients using AT compared to patients not using them. The patients using AT had a smaller mean tumor size (2.98 vs 4.51 cm, P <0.001). A multivariable regression analysis, adjusted for age, sex, and number of comorbidities, showed a lower probability of having a high-grade cancer (OR 0.393, 95% CI 0.195-0.792, P = 0.009), T2 stage (OR 0.276, 95% CI 0.090-0.849, P = 0.025), and tumors larger than 3.5 cm (OR 0.261, 95% CI 0.125-0.542, P <0.001) in patients using AT.
CONCLUSIONS
More favorable histopathological grades, stages, and smaller tumor sizes were found in patients with bladder cancer who experienced macroscopic hematuria and were using AT compared to patients not taking AT.

Review
Pseudoaneurysms of the renal arteries are caused by focal rupture or perforation of the arterial wall, resulting in local bleeding. Such pseudoaneurysms can be observed in conditions such as nodular polyarteritis, penetrating or closed renal injury, and medically induced injuries (such as renal puncture biopsy, percutaneous nephrostomy, or partial nephrectomy). Flexible ureteroscopy (FURS) is performed entirely through the urethra to prevent potentially severe kidney damage. Because of this, almost no renal parenchymal hemorrhage occurs after FURS laser lithotripsy. Only four cases had been documented in the literature as of December 2022. In this report, we describe a 53-year-old man with a history of recurrent kidney stones who underwent FURS laser lithotripsy for bilateral kidney stones. The procedure was smoothly performed, and no active bleeding occurred. However, the patient developed recurrent macroscopic hematuria after discharge from the hospital, and renal angiography revealed a pseudoaneurysm in the distal right kidney. The pseudoaneurysm was treated with selective arterial embolization. Serious complications of FURS surgery are rare, particularly the formation of pseudoaneurysms. We report the present case to bring this potential complication to the attention of urologists.
