Ultrasound bladder wall thickness measurement in diagnosis of recurrent urinary tract infections and cystitis cystica in prepubertal girls

OBJECTIVE

To evaluate urinary bladder wall thickness (BWT) assessed by ultrasound as a diagnostic tool for cystitis cystica.

PATIENTS AND METHODS

This was a 9-year prospective study comprising 120 prepubertal girls. Sixty subjects of whom half underwent cystoscopy represented cases while the other 60 (those with a single urinary tract infection and healthy subjects) represented controls.

RESULTS

Based on receiver operating characteristics (ROC) analysis, BWT discriminated very well between cases and controls with area under the ROC curve close to 1.0. At the optimum cut-off defined at 3.9 mm, negative predictive value (NPV) was 100% leaving no probability of cystic cystitis with BWT <3.9 mm. Positive predictive value (PPV) was also very high (95.2%), indicating only around 4.82% probability of no cystic cystitis in patients with BWT values ≥3.9 mm. BWT could also distinguish between healthy subjects and those with a cured single urinary tract infection, although discriminatory properties were moderate (area under ROC 86.7%, PPV 78.8%, NPV 85.2%).

CONCLUSION

Ultrasound mucosal bladder wall measurement is a non-invasive, simple and quite reliable method in diagnosis of cystitis cystica in prepubertal girls with recurrent urinary tract infections.

Cystitis glandularis forming a tumorous lesion in the urinary bladder: A rare appearance of disease

We report a rare appearance of cystitis glandularis forming a tumorous lesion with blueberry spots in the urinary bladder. A 49-year-old woman was admitted to our hospital with pollakisuria and recurrent gross hematuria. Urine examination showed no pyuria. Computed tomography (CT) scan showed an extravesical invasive mass and cystoscopy revealed a non-papillary tumor with blueberry spots in the bladder. Transurethral resection (TUR) was performed. Histopathological examination revealed cystitis glandularis with cystitis cystica in the part. Postoperative CT scan and cystoscopy showed reduction of the mass in the bladder without any treatments. She is currently well with no evidence of tumor growth three months after TUR.

Ureteritis cystica - A rare urological condition

Ureteritis cystica is a rare benign condition. In this report, we have presented the case of a patient with a left upper back pain. The CT scan showed multiple irregular filling defects in the upper left ureter and the left renal pelvis. During the ureteroscopy, multiple yellow cystic lesions were seen in the proximal part of the left ureter and in the renal pelvis.

The pathology report described cystic structures coated with single line cubic metaplastic epithelium. Ureteritis cystica should be considered in a differential diagnosis, in case of atypical radiological findings. No active treatment is required when confirmed.

Bladder outlet obstruction secondary to posterior urethral cystitis cystica & glandularis in a 12-year-old boy. A rare case scenario

Urethral cystitis cystica and cystitis glandularis in children are extremely rare condition. Mainly manifested as weak urine flow. Other symptoms may occur, such as terminal hematuria, urgency, frequency, and urinary incontinence. In ultrasound examinations, children usually have high post-void residual urine volume. Transurethral visualization and resection of lesions is a method of diagnosis and treatment. Close follow-up is necessary because recurrence may occur. In addition, systemic corticosteroids may slow down its regrowth.

In the current case report, we discussed the clinical presentation and management of urethra cystitis cystica, and cystitis glandularis in a 12-year-old boy.

Difficult cystoscopy due to "Elongated" urethra- think of pelvic lipomatosis

Pelvic lipomatosis is a rare, proliferative disease with unknown etiology involving an overgrowth of normal fat in the pelvic retroperitoneal space. ^1-5 Cystitis glandularis or cystitis cystica can be observed in 75% of patients with pelvic lipomatosis. ⁵ We describe a 44-yr-old chronic smoker with suspicion of bladder mass who was referred to us following an inconclusive cystoscopy due to an "elongated” urethra and was later diagnosed to be a case of pelvic lipomatosis with cystitis cystica. Because the association of this condition with bladder adenocarcinoma and the possibility of obstructive uropathy later, we have kept the patient on close follow-up.

Benign Diseases of the Bladder

Benign diseases of the bladder often present diagnostic challenges to practicing pathologists due to their diverse nature and ability to mimic a variety of epithelial or mesenchymal neoplasms. Categories of benign bladder disease include infectious cystitis, noninfectious cystitis, reactive proliferative processes, and benign processes that secondarily involve the bladder. An understanding of the key clinical and morphologic features of these lesions and the useful ancillary techniques specific for these entities is critical to the correct diagnosis of these lesions. This article reviews the key features of these benign bladder diseases and highlights methods to distinguish these lesions from other benign and malignant processes involving the bladder.

[A case of pyeloureteritis cystica: a diagnosis to keep in mind]

The diagnosis of pyeloureteritis cystica is rare. Data from the literature about this disease are limited. Pyeloureteritis cystica is described as a benign inflammatory disease of the urinary tract, resulting from chronic inflammation of the urothelium. Radiologically, it is characterized by multiple rounded incomplete images of the urinary tract. The histology can confirm the diagnosis or eliminate differential diagnosis. We report the case of a pyeloureteritis cystica in a 64-year-old man, who had a chronic haematuria since ten years.
