It has been reported by numerous observers that late in pregnancy and in the puerperium bacteria can frequently be found in the bladder urine of women who have no other symptoms of infection of the urinary tract. The work reported in this paper was undertaken to define more exactly the incidence, character, and significance of bacteria recovered from the urinary tract of such women. Much of the...

Tumours of the bladder in workmen making dyestuffs were first observed in 1895, but only in relatively recent years have the responsible compounds been recognised. Similar cases have been known to occur in workers in the rubber industry. The actual tumours are similar to those of non-occupational origin, and substantially reduce the expectation of life. There is usually a long latent period bet...

Primary tumors of the appendix are rare, while malignant villous adenoma of the appendix invading the urinary bladder is extremely uncommon. We reported the present case of a 63-year-old male with malignant villous adenoma of the appendix invading the urinary bladder. The conventional cystoscope demonstrated a mass at the front right side wall of the urinary bladder, which misdiagnosed as bladd...

This study utilized magnetic resonance imaging (MRI) to monitor the real-time status of the urinary bladder in normal and diseased states following cyclophosphamide (CYP)-induced cystitis, and also examined the role of the phosphoinositide 3-kinase (PI3K) pathway in the regulation of urinary bladder hypertrophy in vivo. Our results showed that under MRI visualization the urinary bladder wall wa...

Objective: Transitional cell carcinoma (TCC) of the urinary bladder is the second common cancer of the genitourinary tract. Several parameters such as clinical and pathological parameters, molecular factors, and etc play a role in determination of prognosis and type of treatment. In this research study, ...

Pheochromocytoma of the urinary bladder is often misdiagnosed as it is a rare tumor. In this report, we described a case with primary pheochromocytoma of the urinary bladder. We specifically conversed the diagnostic role of X-ray computed tomography and sonography to identify the location of tumor within urinary bladder compared to other malignant or benign tumors in the bladder, and exclude ot...

The clinical feature of bladder pheochromocytoma is usually typical, but the diagnosis is occasionally delayed because of the rarity of this neoplasm. The oldest patient previously reported is 78 years old. In this report, we present an 81-year-old woman with unsuspected bladder pheochromocytoma.

We report a case of primary malignant melanoma of the urinary bladder. Exclusion of other sites of melanoma confirmed the primary character of the tumor, and careful histologic examination proved it to be malignant melanoma. Six previously reported cases of bladder melanoma are reviewed. Therapy and prognosis are discussed.
