Moreover, it usually occurs in immunocompromised patients, especially recipients of renal transplants or patients with a history of previous urological procedures. Due to the rarity of the entity and the slow growth of Corynebacterium species, appropriate treatment is often delayed due to difficulties in diagnosis and resistance to numerous antibiotics. We report a case of encrusted Encrusted cystitis is a rare condition in which infection by urea-splitting bacteria, most commonly Corynebacterium urealyticum, can lead to extensive bladder calcification.
This bacterium can form biofilms and may persist if calcifications are not completely removed. This opportunistic pathogen mainly causes acute cystitis, pyelonephritis, encrusted cystitis, and Corynebacterium glucuronolyticum in Prostatasekret pyelitis. The timely diagnosis and management in this otherwise healthy patient was facilitated by characteristic imaging, cystoscopy, and histologic findings confirmed by results of prolonged urine cultures and 16S ribosomal RNA rRNA gene sequencing of the microbe.
Keywords: encrusted cystitis, Corynebacterium glucuronolyticum, urea-splitting bacterial infection, cystoscopy, sequencing, 16S rRNA men. Corynebacterium species grow slowly and are often missed in rapid urine cultures, especially if the bacterial load is low, and thus present a potential diagnostic challenge. Thus, there can be a delay in diagnosis and treatment if this entity is not considered in a patient with dysuria and hematuria, especially in a post—renal transplantation scenario, post-urinary tract surgery, or instrumentation.
A, Axial computed tomography CT image showing thickened bladder wall arrow. B, Cystoscopy shows diffuse and complete involvement of the bladder wall by multiple yellow-tan to tan-white, necrotic-appearing lesions. Empirical antibiotic treatment with ciprofloxacin did not improve his Corynebacterium glucuronolyticum in Prostatasekret.
Urinalysis results revealed hematuria, pyuria, and proteinuria; however, the results of the urinary culture were negative. Empiric clindamycin therapy was started; also, a CT scan was obtained, which demonstrated marked thickening and edema of the bladder wall with several areas of calcification that we believed represented an infection or a neoplasm Image 1A.
Results of Corynebacterium glucuronolyticum in Prostatasekret subsequent cystoscopic examination showed a diffusely inflamed bladder with multiple yellowtan to tan-white, easily crumbled, necrotic-appearing lesions Image 1B.
The histological examination of the Corynebacterium glucuronolyticum in Prostatasekret biopsies showed mucosal ulceration, acute inflammation, and extensive calcified necrotic debris replacing the bladder mucosa Image 2A and 2B. We also observed chronic inflammation including eosinophils www. We noted no granulomas or eggs. The results of a Brown and Hopps tissue Gram stain were negative. The results of a Gram-stained smear of the urine remained negative.
Results of a culture performed on blood agar Thermo Fisher Scientific Inc.

The isolate produced a this condition. The patient encrustation includes schistosomiasis, tuberculosis, continued to display symptoms after prolonged oral urea-splitting bacterial infections Corynebacterium or vancomycin treatment and cystoscopies.
Thereafter, we Proteusnecrotic urothelial carcinoma, and malakoplakia. The patient has been cyclophosphamide or mitomycin. Previously reported cases of Corynebacterium glucuronolyticum in Prostatasekret cystitis have occurred in patients with predisposing factors. Previous urological procedures, prolonged catheterization, or long- Discussion term hospitalization with broad-spectrum antibiotic therapy have most commonly been reported as causative factors.
The erythematosus, or vasculitis. This particular type of bacteria has been isolated from the genitourinary tract of humans, predominantly men, as shown in a recently reported rare case of nongonococcal urethritis caused by C. Appropriate treatment is often delayed due to misdiagnosis and resistance to many antibiotics. Corynebacterium glucuronolyticum in Prostatasekret includes appropriate antimicrobial therapy, urine acidification, and surgical removal of encrustations.
Corynebacterium is typically sensitive to glycopeptides, including vancomycin and teicoplanin. Acidification of the urine has a synergistic effect with antibiotics by dissolving the calcified encrustations and Corynebacterium glucuronolyticum in Prostatasekret the formation of additional encrustations.
Urine is acidified with oral or topical acidic preparations. Application of a topical acidic solution through a catheter or nephrostomy tube is usually needed, especially at the start of Corynebacterium glucuronolyticum in Prostatasekret. Finally, surgical resection of encrustations via cystoscopy is usually necessary and often requires multiple procedures.
