RESUMEN

A man in his 70s suffered cardiac arrest, and his family initiated cardiopulmonary resuscitation after placing an emergency call. The initial waveform of the automated external defibrillator performed by emergency medical technicians revealed ventricular fibrillation. The patient received cardiovascular life support, including direct current countershock, and was transported to the hospital. Upon arrival, he underwent extracorporeal cardiopulmonary resuscitation using an automated chest compression device. Additionally, an intra-aortic balloon pumping was introduced after coronary angiography and percutaneous coronary intervention. Plain computed tomography images revealed leakage of the contrast medium used during coronary angiography in the bilateral renal pelvis and perirenal area as well as bladder retention. Furthermore, a urine test revealed gross hematuria. There were no findings of prostatic hypertrophy or urinary tract disease. Based on the patient's clinical course, injury caused by chest compression was the most likely etiology of urinary tract injury, which must be considered in such patients. The patient was discharged with cerebral performance category 1, without any complication except urinary tract.

RESUMEN

Scrub typhus is caused by Orientia tsutsugamushi, a Gram-negative coccobacillus. It comprises three strains: Karp, Gilliam, and Kato. Cases of scrub typhus are usually found in the Asia-Pacific region, and their presentation may range from minimal symptoms to multi-organ involvement, with or without the presence of an eschar mark. Varying manifestations of scrub typhus, such as gangrene, meningoencephalitis, anemia with jaundice, and hematuria, have been observed. In the Kumaun region of northern India, there has been a surge in the number of scrub typhus cases. Typically, this disease is accompanied by an eschar mark, but occasionally it can manifest without one. We report a series of four cases presenting with various unusual symptoms such as gangrene of the limbs, meningoencephalitis, jaundice, and hematuria. Serology for scrub typhus should be considered in all patients with acute febrile illness not responding to treatment, especially in mountainous regions, to prevent the associated mortality.

RESUMEN

Acquired hemophilia A (AHA) is an acquired bleeding disorder caused by neutralizing antibodies (inhibitors) against Coagulation Factor VIII (FVIII:C), causing sudden hemorrhagic symptoms (i.e., subcutaneous bleeding, intramuscular bleeding, and hematuria). Herein, this study is aimed at presenting a case of AHA diagnosed based on hematuria and reviewing patients who were diagnosed with AHA due to hematuria. A 67-year-old woman was referred to Atsugi City Hospital with painless gross hematuria that began 4 weeks before presentation. Contrast-enhanced computed tomography (eCT) revealed an approximately 2 cm mass in the right renal pelvis, and the patient's activated partial thromboplastin time (APTT) was elevated (61.4 s). The day after the endoscopic biopsy, the patient was in shock due to a large retroperitoneal hematoma. Although her condition stabilized after intravenous radioembolization, she underwent emergency surgeries several times because of rebleeding within the next 3 weeks. At that time, APTT was more prolonged at 106.4 s, and the FVIII:C level was 2%. Mixing tests showed an upwardly convex curve after 2-h incubation, indicating the presence of an inhibitor. Factor VIII inhibitor titer was ≥5.1 Bethesda unit (BU)/mL. A combined product of Plasma-Derived Factors VIIa and X (pd-FVIIa/FX), as second-line hemostatic therapy, as well as cyclophosphamide (CYP), were administered after Recombinant Activated Factor VIIa (rFVIIa) had been ineffective. Following this, the Factor VIII inhibitor titer was undetectable, FVIII:C levels were restored, and APTT decreased to within the normal range. Gross hematuria was significantly alleviated. However, the patient died of cytomegalovirus and fungal infections due to prolonged immunosuppressive therapy. Although AHA diagnosed based on hematuria may have a better prognosis than others, there have been occasional cases with severe outcomes. APTT, detected upon initial hematological testing in patients with hematuria, may be a potential indicator of an existing AHA.

RESUMEN

BACKGROUND AND OBJECTIVE: Assessment of patients with hematuria (aH) remains a challenge in urological practice, balancing the benefits of diagnosing a potentially underlying bladder cancer (UCa) against the risks of possibly unnecessary diagnostic interventions. This study analyzes the potential of an mRNA-based urine assay, the Xpert® Bladder Cancer Detection- CE-IVD (Xpert BC-D), in patients with hematuria. MATERIALS AND METHODS: Overall, 368 patients with newly observed painless hematuria and no history of UCa were included in this observational study. Patients received urological workup, including urethrocystoscopy (WLC), upper tract imaging, urine cytology and Xpert BC-D. Patients with positive WLC were recommended to undergo tumor resection (TUR-B). RESULTS: After excluding non-assessable cases, 324 patients were considered for analysis (188 males, 136 females; median age: 61 years). Eight of twenty-eight patients with a positive TUR-B had Ta low grade (LG) tumors; the others were diagnosed with high grade (HG) lesions (Ta: 4, CIS: 2, T1:11, > T1:3). The Xpert BC-D was more sensitive than urine cytology (96% vs. 61%) (p = 0.002). Increased risk ratios (RR) were observed for gross hematuria, gender, urine cytology, and positive Xpert BC-D (all p < 0.05). Age and positive Xpert BC-D remained independent predictors of UCa in multivariate analysis. Simulating a triage with WLC restricted to patients with positive Xpert BC-D could have saved 240 (74.1%) assessments at the cost of missing one pTa LG tumor. CONCLUSIONS: The results suggest a potential role for Xpert BC-D in preselecting patients with hematuria for either further invasive diagnosis or an alternate diagnostic procedure.

RESUMEN

BACKGROUND: Although vaccination has been reported to reduce the morbidity and severity of COVID-19 infection in patients with kidney disease, gross hematuria is frequently reported following vaccination in patients with IgA nephropathy. We investigated the frequency of gross hematuria following COVID-19 vaccination and its effect on renal function in IgA nephropathy patients. METHODS: Adverse reactions after two or more COVID-19 vaccine doses were investigated in 295 IgA nephropathy patients attending Osaka Cty general hospital from September 2021 to November 2022. We compared differences in background characteristics and other adverse reactions between groups with and without gross hematuria after vaccination, and examined changes in renal function and proteinuria. RESULTS: Twenty-eight patients (9.5%) had gross hematuria. The median age of patients with and without gross hematuria was 44 (29-48) and 49 (42-61) years, respectively, indicating a significant difference. The percentage of patients with microscopic hematuria before vaccination differed significantly between those with (65.2%) and without (32%) gross hematuria. Adverse reactions, such as fever, chills, headache and arthralgia, were more frequent in patients with gross hematuria. There was no difference in renal functional decline after approximately 1 year between patients with and without gross hematuria. We also found no significant changes in estimated glomerular filtration rate or proteinuria before and after vaccination in the gross hematuria group. However, some patients clearly had worsening of renal function. CONCLUSIONS: While COVID-19 vaccination is beneficial, care is required since it might adversely affect renal function in some patients.

RESUMEN

Eosinophilic cystitis (EC) is a rare inflammatory condition characterized by eosinophilic infiltration into the bladder wall. It often presents symptoms common to urological issues such as urinary tract infections, hematuria, bladder stones, or bladder neoplasms. Here, we describe a case of a 44-year-old male veteran with a history of multiple tuberculosis episodes who presented to the Emergency Department with dysuria, suprapubic pain, and gross hematuria. Initial imaging and cystoscopy concerned bladder neoplasia; however, subsequent pathological evaluation showed EC. This case underscores the importance of considering EC in the differential diagnosis of bladder tumors, especially when imaging describes bladder wall thickening in a patient without risk factors for bladder malignancy.

RESUMEN

Congenital renal arteriovenous malformations (AVMs) occasionally manifest with recurrent gross hematuria, typically in young populations. Acute abdominal pain without previous episodes of gross hematuria in young women is frequently considered a diagnosis related to obstetric and gynecological conditions or acute appendicitis, excluding the possibility of clot retention, which is more commonly associated with the elderly. A 36-year-old woman with no history of gross hematuria presented with acute lower abdominal pain. Adnexal torsion was initially considered based on her symptoms and ultrasonography findings. However, contrast-enhanced computed tomography (CT) revealed clot retention and delayed contrast excretion in the right kidney. After bladder irrigation, she returned complaining of right flank pain. Subsequent plain CT revealed contrast pooling in the right kidney and hydronephrosis. In addition to these findings, small vessels in the right renal hilum were found to be prominent in the arterial phase on the first contrast-enhanced CT. Finally, angiography of renal arteries confirmed the diagnosis of a congenital cirsoid-type renal AVM, which was successfully treated with ethanol embolization. This case highlights the importance of understanding an atypical presentation of renal AVMs, which is acute abdominal pain, even in the absence of prior gross hematuria and the characteristic CT findings. Early diagnosis of renal AVMs is crucial for preventing potentially serious complications, including repeated clot retention and life-threatening rupture. The diverse clinical manifestations and images of renal AVMs should be recognized to facilitate prompt and accurate diagnosis.

RESUMEN

BACKGROUND: To retrospectively report the safety and efficacy of renal transcatheter arterial embolization for treating autosomal dominant polycystic kidney disease (ADPKD) patients with gross hematuria. CASE SUMMARY: The purpose of this study is to retrospectively report the safety and efficacy of renal transcatheter arterial embolization for treating ADPKD patients with gross hematuria. Materials and methods: During the period from January 2018 to December 2019, renal transcatheter arterial embolization was carried out on 6 patients with polycystic kidneys and gross hematuria. Renal arteriography was performed first, and then we determined the location of the hemorrhage and performed embolization under digital subtraction angiography monitoring. Improvements in routine blood test results, routine urine test results, urine color and postoperative reactions were observed and analyzed. Results: Renal transcatheter arterial embolization was successfully conducted in 6 patients. The indices of 5 patients and the color of gross hematuria improved after surgery compared with before surgery. No severe complication reactions occurred. CONCLUSION: For autosomal dominant polycystic kidney syndrome patients with gross hematuria, transcatheter arterial embolization was safe and effective.

RESUMEN

PURPOSE: This study aimed to discuss the correlation between gross hematuria and postoperative upstaging (from T1 to T3a) in patients with cT1 clear cell renal cell carcinoma (ccRCC) and to compare oncologic outcomes of partial nephrectomy (PN) and radical nephrectomy (RN) in patients with gross hematuria. METHODS: A total of 2145 patients who met the criteria were enrolled in the study (including 363 patients with gross hematuria). The least absolute selection and shrinkage operator logistic regression was used to evaluate the risk factor of postoperative pathological upstaging. The propensity score matching (PSM) and stable inverse probability of treatment weighting (IPTW) analysis were used to balance the confounding factors. The Kaplan-Meier analysis and multivariate Cox proportional risk regression model were used to assess the prognosis. RESULTS: Gross hematuria was a risk factor of postoperative pathological upstaging (odds ratio [OR] = 3.96; 95% confidence interval [CI] 2.44-6.42; P < 0.001). After PSM and stable IPTW adjustment, the characteristics were similar in corresponding patients in the PN and RN groups. In the PSM cohort, PN did not have a statistically significant impact on recurrence-free survival (hazard ratio [HR] = 1.48; 95% CI 0.25-8.88; P = 0.67), metastasis-free survival (HR = 1.24; 95% CI 0.33-4.66; P = 0.75), and overall survival (HR = 1.46; 95% CI 0.31-6.73; P = 0.63) compared with RN. The results were confirmed in sensitivity analyses. CONCLUSIONS: Although gross hematuria was associated with postoperative pathological upstaging in patients with cT1 ccRCC, PN should still be the preferred treatment for such patients.

RESUMEN

Ruptured renal artery aneurysms are uncommon. Although the increased use of endovascular technologies, controversy persists over the management. Contained rupture may be more difficult to diagnose, hence delay the management. We report a case of contained rupture of renal artery aneurysm treated with selective embolization prior to nephrectomy.

RESUMEN

Post-infectious glomerulonephritis (PIGN) is an immune complex mediated glomerular injury occurring because of an infection, most commonly with group A beta-hemolytic streptococcus in children. C3 glomerulopathy (C3G) is a distinct clinicopathological entity occurring secondary to dysregulation of alternate complement pathway encompassing both C3 glomerulonephritis (C3GN) and dense deposit disease (DDD). While most patients with PIGN attain complete remission with normalized complement levels by 6-8 weeks after presentation, patients with C3G continue to have hypocomplementemia with high rates of progressive kidney disease. Here, we report a patient diagnosed with dense deposit disease after his initial presentation with PIGN three years prior. While current literature continues to explore the overlapping and distinguishing features of PIGN and C3G, including how underlying defects in the alternate complement pathway may commonly contribute to both diseases, this case further exemplifies the importance of recognizing the clinico-pathogenic features of PIGN and C3G in pediatric patients with glomerulonephritis.

RESUMEN

A 71-year-old male with benign prostatic hyperplasia managed by self-catheterization presented with gross hematuria. A CT scan of abdomen and pelvis demonstrated abnormal bladder appearance with right sided mass and a diverticulum. Patient underwent transurethral resection of bladder tumor. Pathology was significant for high-grade muscle-invasive angiosarcoma. The malignant cells showed positive staining for vimentin and CD31. Given patient's underlying comorbidities and following multidisciplinary discussion, hospice care was pursued. The aim of this case report is to provide an overview on clinical presentation, diagnosis, and current management of this rare entity of genitourinary sarcoma.

RESUMEN

Emphysematous cystitis is a rare type of urinary tract infection that is characterized by the accumulation of gas within the walls and lumen of the urinary bladder. In rarer instances, pneumoperitoneum may accompany emphysematous cystitis. When pneumoperitoneum is suspected through imaging studies in patients with emphysematous cystitis, surgical abdominal exploration is frequently performed considering the possibility of bladder perforation or coexistence of intestinal perforation. We successfully managed a case of emphysematous cystitis accompanied with pneumoperitoneum conservatively. A 90-year-old woman hospitalized with a gastric ulcer developed abrupt lower abdominal pain and hematuria. Contrast-enhanced CT revealed gas within the bladder wall, which was consistent with emphysematous cystitis, and pneumoperitoneum. No obvious bowel or bladder perforation was observed in the CT scan. Regarding her high surgical risk and clinical stability, surgical abdominal exploration was not performed, and she was managed conservatively with urethral catheter placement and antibiotics. She recovered with the treatment, and CT imaging obtained on day 18 demonstrated resolution of the bladder wall emphysema and no signs of pneumoperitoneum. We performed a literature review using MEDLINE and Japana Centra Revuo Medicina Web and confirmed 13 previously reported cases of emphysematous cystitis and pneumoperitoneum. Based on the review of these 13 cases and our case, it is difficult to predict the presence of bladder perforation solely based on peritoneal signs in physical findings or ascites on CT scans. Therefore, it would be preferable to perform surgical abdominal exploration to make a definite diagnosis and select an appropriate treatment. However, the fact that at least eight out of the 10 cases managed conservatively survived suggests that there is a specific clinical entity among patients who present with emphysematous cystitis and pneumoperitoneum that can be safely managed conservatively. Further accumulation of cases and research is necessary to determine which cases can be treated conservatively.

RESUMEN

BACKGROUND: The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been followed by many reports of the development and relapse of autoimmune diseases associated with SARS-CoV-2 vaccination. Some of these reports have involved relapse or onset of immunoglobulin A (IgA) nephropathy following SARS-CoV-2 vaccination. Here, we report on a patient with IgA nephropathy who presented with gross hematuria and rapidly progressive glomerulonephritis following SARS-CoV-2 vaccination. CASE PRESENTATION: A 63-year-old male patient with a history of habitual tonsillitis underwent bilateral tonsillectomy. He had a history of alcoholic cirrhosis of the liver and microscopic hematuria and proteinuria were indicated during a health checkup 2 years before hospital admission. He developed hematuria after the SARS-CoV-2 vaccination, which led to rapidly progressive glomerulonephritis, for which he was hospitalized. A renal biopsy led to the diagnosis of IgA nephropathy. Although pulse steroid therapy during his condition resulted in hepatic encephalopathy, three courses combined with mizoribine improved his renal function. CONCLUSION: SARS-CoV-2 mRNA vaccines activate T cells, which are involved in the pathophysiology of IgA nephropathy. Therefore, this case suggests that the exacerbation of IgA nephropathy by the vaccine favors the vasculitis aspect of the disease.

RESUMEN

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can affect multiple organs due to activation of an inflammatory response. One of the key components of this response is the activation of immunoglobulin A (IgA), thus causing endothelial injury and inflammation. Henoch-Schönlein purpura (HSP) has been rarely reported in adult patients as a complication of the coronavirus disease 2019 (COVID-19) infection. In this report, we present a case of HSP occurring one week after the diagnosis of COVID-19 in a 23-year-old woman. Her symptoms included nausea, vomiting, diffused abdominal pain, joint pain, hematuria, and palpable purpura of the lower extremities. She was treated with intravenous methylprednisolone sodium succinate, followed by oral prednisone therapy, which resulted in clinical improvement, including resolution of abdominal and joint pain as well as skin rashes, without remaining renal complication.

RESUMEN

Background: Children with febrile urinary tract infections (UTIs) are prone to kidney scarring if they are not treated promptly; however, ambiguous symptoms before fever onset makes the early detection of UTIs difficult. Our study aimed to identify urethral discharge as an early manifestation in children with UTI. Methods: This study enrolled 678 children younger than 24 months with paired urinalysis and culture performed between 2015 and 2021; 544 children were diagnosed with UTIs. Clinical symptoms, urinalysis, and paired urine culture results were compared. Results: Urethral discharge was observed in 5.1% of children with UTI and yielded a specificity of 92.5% for diagnosing UTI. Children with urethral discharge had a less severe UTI course, furthermore, nine of them received antibiotics before fever occurred and seven of them were free of fever during UTI course. Urethral discharge was associated with alkalotic urine and Klebsiella pneumonia infection. Conclusions: Urethral discharge is an early symptom in children with UTI; it may present before fever onset and help ensure prompt antibiotic intervention.

RESUMEN

Introduction and Objective: Continuous bladder irrigation (CBI) is used in a variety of clinical settings, including post-transurethral surgery and the emergency department. Currently, CBI administration relies on nurses to diligently monitor and switch irrigation bags, as well as titrate the inflow rate based on effluent color. Inappropriate administration can result in discomfort to patients, clot urinary retention, repeat injury to the pathologic or surgical site, extended hospital stays, and even operative management. Our objective was to create an autonomous CBI system that decreases the incidence of disrupted irrigation flow and monitors the outflow to alert clinicians of critical events. Methods: 3D printing and off-the-shelf microcontrollers were used to design a device to fit the needs identified by stakeholders at our institution. An in vitro model of the bladder was created to test our design. The mechanical, electrical, and software subsystems were adjusted accordingly to meet our design requirements. Results: Our in vitro CBI model was able to simulate routine CBI administration with sudden bleeding. Bovine blood was used to simulate the bleeding events. A device was created that met identified stakeholder needs. Accurate detection of critical bleeding events, catheter blockage, and empty irrigation bags were achieved. The device responds to bleeding appropriately by increasing the irrigation rate. When the catheter is blocked, it stops the irrigation and alerts the nurse. Our system accurately titrated the irrigation rate to match a set outflow blood level parameter, conserving irrigation and minimizing nursing workload. Continuous monitoring of CBI effluent was recorded. Conclusions: We anticipate our device will decrease the cognitive load on nurses in busy clinical settings and improve workflow. Moreover, the detection of critical events will likely decrease patient morbidity. Continuous monitoring of the CBI outflow may prove to be a new clinical decision-making tool for ongoing hematuria. Clinical trial is pending.

RESUMEN

While conventional lipomas represent the most commonly seen benign mesenchymal tumor in adults, their occurrence in the bladder wall is exceptionally rare. This report details a rare case of a bladder lipoma, a benign tumor primarily composed of mature adipocytes, presenting as gross hematuria in a 68-year-old male. Despite the patient's previous history of left nephrectomy, no significant pathological findings were initially observed. The bladder lipoma was detected via cystoscopy as a polypoid mass on the posterior bladder wall and confirmed through transurethral resection of the bladder tumor (TUR-BT). Histopathological analysis verified the mass as a bladder lipoma composed of mature adipocytes. Following a specific postoperative follow-up period, no recurrence of the tumor was observed, suggesting successful treatment. This case underscores the clinical significance of considering bladder lipoma in differential diagnoses of bladder tumors, especially in patients presenting with gross hematuria, given its exceptional rarity.
