Methotrexate (MTX)-related lymphoproliferative disease (LPD) is one of the most prominent late complications associated with MTX treatment. Although MTX-related LPD exhibits a relatively high incidence of extranodal disease, the incidence of disease in a urinary bladder is very low. The present study reports the case of a patient with MTX-related LPD involving a urinary bladder mass. A 75-year-old female patient, who had been receiving MTX for ~15 years, was referred to the hospital due to fever and hematuria. A computed tomography scan revealed the thickening of the urinary bladder wall, hydronephrosis and lymph node swelling. The histopathological findings of the urinary bladder mass resulted in a diagnosis of MTX-related LPD. Although MTX withdrawal did not have any effect, the subsequent chemotherapy resulted in complete remission. Although MTX-related LPD in the bladder is rare, it is pertinent to consider MTX-related LPD when hematuria is observed during MTX therapy.

UNASSIGNED: Bladder papilloma, a rare benign tumor of the urinary tract, accounts for 1-4 % of bladder tumors. Its distinct features, diagnosed through light microscopy, include architectural and cytological characteristics. Despite its rarity, bladder papilloma is clinically significant due to its distinct traits, low recurrence risk, and potential progression to other urothelial neoplasms. Understanding this condition is crucial for early diagnosis and optimal patient care.
METHODS: A 66-year-old male with benign prostatic hyperplasia presented with one month of intermittent hematuria. Physical examination and laboratory tests were unremarkable. Imaging revealed an 11 × 10 × 7 mm echogenic nodular lesion with calcifications on the right bladder wall. Cystoscopy identified a polypoid lesion, leading to transurethral resection. Histopathological examination confirmed bladder papilloma without malignant features.
UNASSIGNED: Bladder papilloma typically presents with hematuria, mainly in younger patients, with low recurrence and rare progression to aggressive cancers. Diagnosis involves endoscopy and resection, followed by cystoscopic surveillance. Understanding its classification, characteristics, and risk factors aids in accurate management.
CONCLUSIONS: Bladder papilloma diagnosis relies on light microscopy, with hematuria as a primary symptom, often in younger patients. Recurrence risk is low, and progression to aggressive cancers is rare. Diagnosis involves endoscopy, resection, and cystoscopic follow-up. This case enhances our understanding of bladder papilloma, contributing to improved care.

BACKGROUND: Abscess of the bladder wall is a rare urological disorder, with a few cases recorded in the literature. The finding of a bladder wall mass via computed tomography (CT) imaging in a visiting patient is the subject of this report.
METHODS: A 37-year-old woman with persistent pain in the suprapubic area and lower urinary tract symptoms was examined as a case study. Through a CT scan revealed an inhomogeneous structure in the anteroinferior part of the right bladder. A cystoscopy procedure followed by transurethral resection was performed to remove the mass, which was found to be an abscess. A Foley catheter with irrigation was administered after surgery, and the patient goes home in three days.
CONCLUSIONS: the patient had no symptoms or discomfort in the lower urinary tract after follow-up. Despite the rarity of bladder wall abscesses, cystoscopy can be used to aid diagnosis. Transurethral resection of bladder wall can reduce the mass and eliminate the possibility of malignancy.

This retrospective study evaluated the safety and efficacy of fluoroscopy-guided urethral catheterization in patients who failed blind or cystoscopy-assisted urethral catheterization. We utilized our institutional database between January 2011 and March 2023, and patients with failed blind or cystoscopy-assisted urethral catheterization and subsequent fluoroscopy-guided urethral catheterization were included. A 5-Fr catheter was inserted into the urethral orifice, and the retrograde urethrography (RGU) was acquired. Subsequently, the operator attempted to pass a hydrophilic guidewire to the urethra. If the guidewire and guiding catheter could be successfully passed into the bladder, but the urethral catheter failed pass due to urethral stricture, the operator determined either attempted again with a reduced catheter diameter or performed balloon dilation according to their preference. Finally, an appropriately sized urethral catheter was selected, and an endhole was created using an 18-gauge needle. The catheter was then inserted over the wire to position the tip in the bladder lumen and ballooned to secure it. We reviewed patients\' medical histories, the presence of hematuria, and RGU to determine urethral abnormalities. Procedure-related data were assessed. Study enrolled a total of 179 fluoroscopy-guided urethral catheterizations from 149 patients (all males; mean age, 73.3 ± 13.3 years). A total of 225 urethral strictures were confirmed in 141 patients, while eight patients had no strictures. Urethral rupture was confirmed in 62 patients, and hematuria occurred in 34 patients after blind or cystoscopy-assisted urethral catheterization failed. Technical and clinical success rates were 100%, and procedure-related complications were observed in four patients (2.2%). The mean time from request to urethral catheter insertion was 129.7 ± 127.8 min. The mean total fluoroscopy time was 3.5 ± 2.5 min and the mean total DAP was 25.4 ± 25.1 Gy cm2. Balloon dilation was performed in 77 patients. Total procedure time was 9.2 ± 7.6 min, and the mean procedure time without balloon dilation was 7.1 ± 5.7 min. Fluoroscopy-guided urethral catheterization is a safe and efficient alternative in patients where blind or cystoscopy-assisted urethral catheterization has failed or when cystoscopy-urethral catheterization cannot be performed.

A foreign body in the urinary bladder is an uncommon finding in urology emergencies. There are several ways in which intravesical foreign bodies can occur, including iatrogenic injuries, self-insertion for pleasure, sexual abuse, assault, and migration from adjacent sites. This case report is about an interesting presentation of a 36-year-old male who presented to the urology outpatient department with a burning sensation and dribbling while urinating for 1 month. An X-ray of the pelvis revealed multiple radiodensities (morphology was suggested as magnetic balls) in the pelvic soft tissues. Cystoscopy was performed and three-pronged forceps were utilized to remove the magnetic foreign bodies. The patient had an insignificant hospital course and was discharged with analgesics and antibiotics.

According to reports, there are 1.9-3.6 incidences of IUD migration and uterine perforation for every 1000 IUD insertions. It is important to note that bladder perforation caused by a misplaced IUD is uncommon and is thought to happen most frequently during insertion. Here, we describe a patient who presented with symptoms related to the malposition of IUD inside the bladder. It is feasible to draw the conclusion that the cystoscopy technique should be taken into consideration as a suitable therapy option for such injuries in this organ. When a problem cannot be effectively treated by cystoscopy alone, laparotomy should be considered.

Mullerianosis is a rare, complex, benign tumor most commonly found in the bladder and often mistaken for a neoplastic lesion.  Herein, we report a case of mullerianosis in a 65-year-old woman who presented with an incidental 2 cm bladder mass found on cross-sectional imaging.  A mixed cystic and solid tumor was identified on cystoscopy and a transurethral resection of the suspected tumor was performed with histopathology confirming a final diagnosis of mullerianosis.  While an unusual diagnosis, mullerianosis of the urinary bladder needs to be correctly identified to provide appropriate treatment and avoid misdiagnosis.

This case report describes the presentation, diagnosis, and surgical management of a rare vesical ectopic pregnancy in a 36-year-old woman with a history of multiple cesarean sections. The patient presented with symptoms of suprapubic pain, fever, and amenorrhea. An initial ultrasound indicated retained products of conception, leading to a preliminary diagnosis of septic miscarriage. However, subsequent rescanning revealed an empty uterus and a non-viable fetus within the bladder, connected to the uterine cavity. Cystoscopy confirmed the presence of fetal parts inside the bladder. Finally, a laparotomy was performed and the fetus was removed from the bladder with repair of the underlying uterovesical fistula. An uneventful postoperative period ensued. The literature review revealed only four previously reported cases with similar overall presentations. This case highlights the importance of considering vesical ectopic pregnancies in patients with a history of cesarean sections and unusual symptoms, as prompt surgical intervention is crucial for ensuring successful management of the condition.

The present study reports the clinical data of a patient with renal venous malformation misdiagnosed as carcinoma. CT revealed hematocele in the left renal pelvis and ureter. CTU: the left renal pelvis and calyces showed a slightly high density shadow, a size of about 2.6 cm*1.5 cm, and mild-to-moderate enhancement was found at the edge of the lesion. Enhanced MR showed that irregular mass abnormal signal was observed in the lower calyx of the left kidney and the lesions were cast, with short T1 and slightly long T2 signals. The secondary bleeding or mucus of low-grade malignant tumor became suspicious. The patient underwent cystoscopy and left ureteroscopy under general anesthesia on December 3, 2021. Bloody urine can be seen on the left side, and multiple blood clots in the left renal pelvis can be detected. After washing, dark red bloody necrotic substances can be seen. Pathology suggests that renal venous malformation, accompanied by bleeding and thrombosis, is located in the renal medulla, involving the renal calyx, rupture and bleeding of the renal calyx, and obvious local bleeding of surrounding renal tissue. Follow-up for more than 1 year showed that the patient\'s condition was stable. When patients have renal colic with hematuria, enhanced CT suggests that renal mass is mild-to-moderate continuous enhancement, enhanced MRI suggests short T1 and long T2, considering that the mass may be accompanied by bleeding, and ureteroscopy suggests that dark red bloody necrotic substances should be considered in the diagnosis of renal venous malformation.

UNASSIGNED: Urothelial carcinoma of the bladder predominantly affects adults with rare cases in young patients. This manuscript presents a rare case of urothelial carcinoma highlighting clinical characteristics, diagnosis, treatment, and prognosis in this age group. Our aim is to raise awareness among healthcare professionals for improved outcomes in children and adolescents with bladder urothelial carcinoma.
METHODS: A 17-year-old male presented with hematuria and urinary symptoms. No history of smoking, alcohol, surgeries, family conditions, or medications. The patient had environmental chemical exposure near an oil refinery. An initial ultrasound and Cystoscopy showed a sizable bladder tumor. A complete TURBT was done, followed by cauterization and catheter placement. The tumor was diagnosed as low-grade urothelial carcinoma (pT1). Follow-up cystoscopies after 3 and 9 months showed no recurrence.
UNASSIGNED: Urothelial bladder carcinoma (UBC) is linked to occupational exposure and smoking. Limited research exists on UBC in young patients, but genetic factors and environmental exposure may play a role. In young individuals, UBC typically presents as low-grade, non-muscle invasive tumors (NMIBC). Transurethral resection may be sufficient for low-grade tumors, and postoperative follow-up with ultrasound is important. Larger tumors have a higher risk of recurrence and progression.
CONCLUSIONS: The present case emphasizes the need to consider urothelial bladder carcinoma as a potential cause of hematuria in young patients and conduct a thorough evaluation of all risk factors. Future research is needed to establish evidence-based guidelines for managing this condition in pediatric and adolescent patients.
