A previously healthy 44-year-old male was admitted with the chief complaint of intermittent gross hematuria. On initial ultrasonographic and CT examination, a grossly protruding intravesical tumor was noted and, under the impression of a malignant bladder tumor, transurethral resection was performed. The histological findings were spindle cells with elongated cytoplasm with rare mitotic figures distributed in myxoid stroma, consistent with diagnosis of inflammatory pseudotumor of the bladder. The benign nature of this tumor warrants conservative surgical management, usually consisting of transurethral resection or partial cystectomy. No reports of metastasis have been reported following complete excision. Therefore, any suspicion and recognition of this entity is imperative to avoid performing an irreversible radical procedure.

An ultrasonic scanner in the field of urology is described that can be used for transurethral as well as for transrectal scanning of the bladder and prostate. The bladder was visualized best by transurethral scanning, while the rectal approach was preferable for examination of the prostate. Transurethral ultrasonography was performed in 7 patients with bladder cancer. Transrectal ultrasonography was performed in 21 controls and 41 patients with prostatic disease. The following results were obtained: 1. Diagnostic accuracy of the staging of transurethral ultrasonography was 85.7% in bladder cancer. 2. The average values of maximum anterioposterior, superio-inferior and transverse diameter. obtained from ultrasonogram were 2.43+/-0.29cm, 3.27+/-0.41cm, 4.07+/-0.91cm in control group ;3.11+/-0.6lcm, 4.16+/-0.66 cm, 4.71+/-0.76cm in B.P.H.; 3.65+/-0.46cm, 4.88+/-0.23cm, 5.98+/-0.18cm in prostatic cancer. 3. Diagnostic accuracy of transrectal ultrasonography was 93% in B.P.H. and 80% in prostatic cancer. 4. Transurethral ultrasonography enabled us to determine the degree of tumor invasion of the bladder wall and was useful to help select appropriate therapy. Transrectal ultrasonography has proved especially in estimating prostatic size and in detecting pathology.

The inflammatory pseudotumor of the urinary bladder is rare, especially in children. It is a benign proliferative lesion of the submucosal stroma easily mistaken for a sarcoma clinically, so it should be differentiated from a malignant neoplasm. We report the case of bladder inflammatory pseudotumor in a 7-year-old girl.

In order to study the pathogenesis, clinical and pathological characteristics of proliferative lesions of the bladder, 50 cases of proliferative lesions of the bladder from 150 patients with complaints of frequency, urgency, hematuria and dysuria were subjected to cystoscopic biopsy of the suspicious foci in the bladder. In combination with the symptoms, urine and urodynamics, the relationship of proliferative lesions of the bladder to the inflammation and obstruction of the lower urinary tract was analyzed. Of the 50 cases of proliferative bladder lesions, 44 cases (88%) had lower urinary tract infection and 29 (58%) lower urinary tract obstruction. The patients with lower urinary tract obstruction were all complicated with infection. Three cases were associated with transitional cell carcinoma. Malignant cells were detected in 1 case by urinary cytologic examination. Proliferative lesions of the bladder, especially those without other obvious mucosa changes under cystoscopy, are common histological variants of urothelium in the patients with chronic inflammation and obstruction of the lower urinary tract. Chronic inflammation and obstruction of the lower urinary tract might be the causes for proliferative lesions of the bladder. It is suggested that different treatments should be applied according to the scope and histological type of the proliferative lesions.

This case reports muellerianosis of the urinary bladder, showing glandular lesions made up of endocervical type glands, in a 36-yr-old woman. The patient presented with lower abdominal discomfort and pain on voiding. The patient had undergone two Cesarean sections 5 yr and 3 yr earlier. On a pelvic ultrasonography, a well-circumscribed mass, 2.2x0.8 cm in dimension, was found with luminal polypoid projection in the posterior wall of the urinary bladder. The patient had a transurethral resection of the bladder mass. Histologically, the tumor was composed of irregularly shaped glands lined by endocervical mucous epithelium in the muscularis propria of the urinary bladder. Some glands exhibited cystic dilatation and contained mucinous secretions. The glands elicited no desmoplastic tissue reaction. The intraluminal mucin often contained polymorphonuclear leukocytes. The glands were mostly lined by tall columnar and bland looking mucous cells with mucin secretion. The ciliated cells were rarely observed. No endometrial component is noted. It would be appropriate to designate this lesion as "Muellerianosis of the urinary bladder, endocervicosis type". Awareness of the lesion and attention to its typical histologic features should facilitate its crucial distinction from adenocarcinoma.

Primary localized amyloidosis is a rare disease with an excellent prognosis in most cases. We report a case of primary localized amyloidosis of the bladder that was treated with transurethral resection.

Neurogenic bladder in systemic lupus erythematosus (SLE) has been considered to occur rarely. Myelopathy, cyclophosphamide treatment, vasculitis have been implicated as the causes of the bladder pathology in patients with SLE. In this report, we describe a 46-year- old female with SLE who simultaneously combined with the neurogenic bladder. The diagnosis of neurogenic bladder, attributed to peripheral neuropathy, was made on the basis of cystometrography and clinical symptom. Steroid therapy couldn't improve the clinical manifestation of neurogenic bladder despite the amelioration of the other lupus symptom.

Dystrophic calcification can be defined as a calcification that occurs in degenerated or necrotic tissue. It is associated with multiple clinical conditions, such as collagen vascular diseases. It involves the deposition of calcium in soft tissues despite no generalized disturbance in the calcium or phosphorus metabolism, and this is often seen at sites of previous inflammation or damage. Potassium-titanyl phosphate (KTP) laser vaporization of the prostate is safe and relatively bloodless procedure that results in a shorter catheterization, immediate symptomatic improvement, and less severe postoperative irritative symptoms. However, longer follow-up studies or reports about complications are lacking. Here in we report a case of dystrophic calcification and stone formation on the entire bladder neck after performing KTP laser vaporization of benign prostate hyperplasia. That was treated by lithotripsy and transurethral resection.
