Two cases of carcinoma in situ of the bladder treated with radical cystoprostatourethrectomy were evaluted by histologic study of the totally embedded epithelium. Clinical symptomatology consisted of urinary frequency with diminished bladder capacity and pain on voiding. Urinary cytology and multiple biopsies were essential for diagnosis of this lesion. The resected specimens of both cases were fixed in formalin and totally embedded for step sections that were mapped after histopathologic study. In both cases atypical epithelium and carcinoma in situ with foci of microinvasion affected the bladder mucosa and extended continuously to the distal ureters as well as the prostatic urethra. Since the lesion subsequently may result in invasive bladder cancer and often involves the prostatic urethra and distal ureter as in our cases the radical cystoprostatourethrectomy is recommended.

Medical records of 68 horses with urolithiasis were examined. Calculi were in the bladder in 47 horses, urethra in 11 horses, kidneys in 15 horses, and ureter in two horses. They occurred at several sites in six horses. Common clinical signs included hematuria, altered micturition (pollakiuria, dysuria, urinary incontinence), and tenesmus. Weight loss, possibly attributable to chronic renal failure and colic, was associated more commonly with renal and ureteral calculi. Weight loss also occurred in 13% of horses with cystic calculi only. In male horses, most cystic calculi were removed by perineal (ischial) urethrotomy under epidural anesthesia. Although there were few surgical complications with urethrotomy, seven of 15 horses with follow-up suffered recurrent urolithiasis.

Forty patients with carcinoma in situ of the bladder were reviewed. They included 15 patients with primary carcinoma in situ, 8 with secondary carcinoma in situ and 17 with concurrent carcinoma in situ. Twenty-one (66%) of 32 patients with primary or concurrent carcinoma in situ complained of urinary frequency and pain on urination, whereas no patients with secondary carcinoma in situ complained of such symptoms. Nearly all patients with concurrent or secondary carcinoma in situ had gross hematuria, whereas only 7 (47%) of 15 patients with primary carcinoma in situ had gross hematuria. Two patients without any symptoms were diagnosed by incidental positive urinary cytology. Concurrent carcinoma in situ was always associated with multiple papillary tumor. Dominant grade of the papillary tumor was classified as grade 3 in 11 patients and as grade 2 in 6. The simultaneous presence of carcinoma in situ of the urethra was found in 13 (46%) patients and those of the ureter in 17 (74%). Fourteen patients (35%) with carcinoma in situ developed an invasive carcinoma. Of these, 4 (10%) died of cancer. Bacillus calmette-guerin instillation was effective in 13 of 15 patients (87%). These results indicate that carcinoma in situ of the bladder may develop an invasive cancer, may remain in the epithelia, or may be associated with multiple superficial tumor. It should be emphasized that patients with multiple superficial bladder tumor may be associated with carcinoma in situ even if the superficial tumors are of low grade and urine cytology is negative.

Two cases of carcinoma in a diverticulum of the bladder were experienced. The first case was of a 50-year-old male who presented in February, 1981, complaining of asymptomatic microhematuria. The excretory urogram revealed a diverticulum in the left lateral aspect of the bladder which was causing shift of the lower ureter to the median side. The cytology report of voided urine was class III. Diverticulectomy was performed and pathologic findings was a transitional cell carcinoma, grade 1, stage 0. The patient has been free of recurrence for the past 54 months. The second case was of a 67-year-old male with the chief complaint of pollakiuria. Non-papillary tumor in a diverticulum of the bladder was found by cystoscopy and computed tomography. Tumor biopsy and urinary diversion by ileal conduit were performed in the usual manner. The pathologic finding was transitional cell carcinoma of grade 11 malignancy. The patient died of intestinal obstruction on January, 19, 1984, about 15 months after the surgery. The 117 cases of carcinoma in a diverticulum of the bladder we found in the Japanese literature are reviewed briefly.

To induce an experimental model of bacterial cystitis, ten preconditioned dogs underwent bladder irritation with a 0.1% alcoholic solution of salicylic acid followed in 24 hours by an intravesicular infusion of Proteus mirabilis. The dogs were observed for the following 14 days (five dogs) and 17 days (five dogs) and then euthanatized and necropsied. Tenesmus, dysuria, hematuria, and pollakiuria occurred in all dogs, but the severity of these signs diminished with time. The total white cell, neutrophil, and monocyte counts in the peripheral blood increased and urinalysis results were consistent with infection and severe inflammation. The infection persisted for the duration of the study, although the average quantitative bacterial count in urine progressively declined. No changes occurred in the measured clinical chemistry values. Severe inflammation was present on gross examination of the bladder and microscopic examination of the bladder, prostate, and renal pelvis. Less severe inflammation was present on microscopic examination of the urethra and ureter.

This report presents a case of pelvic actinomycotic infection that was accurately diagnosed preoperatively by means of fine needle aspiration. The patient was a 40-year-old black female, gravida 6, para 6, who presented to the emergency room complaining of intermittent, crampy lower abdominal pain of approximately 1 month's duration. She also complained of a recent onset of urinary frequency and urgency without dysuria as well as a change in bowel habits, with recent constipation. Review of the patient's medical history was notable for the placement of a Dalkon Shield IUD 10 years before without subsequent removal, a history of irregular menses in the past year, and treatment for gonorrhea 10 years previously. The patient's last menstrual period was 2 weeks prior to admission. She denied fever and night sweats but had lost 20 pounds in the past 2-3 months. Vital signs were normal. Pelvic examination revealed a firm, fixed uterus, approximately the size of a 14-week pregnancy, and an associated mass extending to the left and inferiorly into the rectovaginal septum. An intravenous pyelogram showed left hydronephrosis and hydroureter, with compression of the ureter at the level of the sacrum. Sigmoidoscopy revealed extrinsic compression of the rectum at 12 cm, the some mucosal edema. A CT scan of the pelvis disclosed an 8 cm mass in continuity with the uterus extending into the lower pelvis, with possible focal erosion of the sacrum. The clinical impression was advanced cervical carcinoma. Transvaginal fine needle aspiration was performed using a 21-gauge spinal needle and a Franzen needle guide. Following a diagnosis of actinomycotic abscess, the patient was placed on tetracycline, due to her penicillin allergy, and taken to surgery. The abdomen was opened and revealed a slightly enlarged uterus. The uterus and cervix were adherent to the left pelvic wall and posteriorly to the rectum by firm, friable tissue. The left fallopian tube and ovary were adherent to this . With some difficulty the uterus was freed, and a total hysterectomy and bilateral salpingo-oophorectomy were performed. The postoperative course was unremarkable, and the patient was discharged on tetracycline. A morphologic diagnosis of actinomycotic infection with abscess formation was made. Sections of the left parametrium revealed multiple microabscesses and sinus tracts surrounded by abundant granulation tissue. Some of the abscesses contained actinomycotic organisms. Chronic endometritis and cervicitis as well as acute and chronic left salpingitis were documented.

Ten patients (4 boys and 1 girl, 4 adult women and 1 man) were operated upon for incontinence due to epispadias (5 children and 2 women), or the result of multiple operations for stress incontinence (2 women), or of a transurethral bladder neck resection (the adult man), using Leadbetter's technique, which is described. In 4 patients with a sufficiently long trigonum, it was not considered necessary to perform ureterovesical reimplantation. Interesting results were obtained as they were assessed as very good in 4 and good in 2 of the 7 cases of epispadias, good in 1 of the 2 cases of sphincter lesions following surgery, and poor after endoscopic resection of the bladder neck in the man. All patients retained a normal upper urinary tract. In those patients who became continent, the new urethra measured 3.3 to 5 cm in length, whereas it was too short and dilated in cases remaining incontinent. Initial pollakiuria improved in the children after several months. These findings suggest that the ureter should be reimplanted in all cases, to allow the formation of a muscular, newly formed urethra of sufficient length. This operation appears to be effective for treating incontinence due to epispadias and traumatic sphincter lesions in women. It gives poor results in incontinence after prostate surgery and from neurological bladder. Reeducation of the child is as important as selection of patients for operation and a strict operative technique.

Of the total number of dogs submitted with complications following ovariohysterectomy (109), eighteen were found to show pathological changes of the kidney and/or excretory urinary ducts. Eleven patients showed specific urological problems such as pollakiuria (7 cases), urinary incontinence (6 cases) and haematuria (5 cases). When there was a reason for doing so, specific urological studies were undertaken, including excretion urography in seven cases, in addition to physical and laboratory studies. During laparotomy and/or post-mortem examination (the latter being carried out in eight dogs), the following adhesions were observed, among others: the cervix stump adhered to the bladder in nine cases, to the right ureter in five and to the left ureter in three cases. Either granulomas at the ovarian stump (one case) or cervix stump (five cases) or actual ligation of the ureters in the ovarian (two cases) or cervix stump ligature (three cases) caused partial or total obstruction, which occasionally resulted in hydro-, pyo- or haemonephrosis, atrophy of the kidney or focal nephritis.

The prevalence, pathologic effects, and treatment of Capillaria plica infection were investigated in two breeding kennels. The prevalence of C plica infection in mature dogs in two kennels (127 dogs) was 76% and 59%. Pups less than 8 months old did not pass C plica eggs in the urine. Age, breed, or sex predilection was not observed in mature dogs. In infected dogs, hematuria, dysuria, and pollakiuria developed without secondary bacterial cystitis. A direct life cycle could not be demonstrated experimentally. Histologically, adult C plica were seen in the submucosa of the bladder and ureter, where they induced a mild inflammatory reaction and submucosal edema.

A 72-year-old female patient presented to our clinic with the chief complaint of gross hematuria and urinary frequency on September 6, 1990. Cystoscopic examination revealed a thumb's head size nonpapillary tumor. The tumor was located adjacent to the orifice of the left ureter. Histological findings of the tumor by transurethral resection (TUR) indicated transitional cell carcinoma with partial signet ring cell carcinoma. No other malignant findings in any other organs including the gastrointestinal tract were noted. Total cystectomy was performed and Indiana pouch was constructed. Histopathological staging was pT1 N0 M0. The patient died of multiple metastasis of the signet ring cell carcinoma on June 22, 1992. This is the thirty-second case of signet ring cell carcinoma of urinary bladder reported in the medical literature in Japan. We investigated 19 alive or unknown cases as follow up and briefly discussed the treatment and outcome of the primary signet ring cell carcinoma of the urinary bladder. The outcome appeared to be somewhat better than previous reports. Total cystectomies were performed in 18 of the 32 cases (56.3%). As noted in past reports, the treatment of our patient consisted of total cystectomy. Twenty-two patients died of signet ring cell carcinoma. Recurrence to the pelvic area was observed in 18 of the 22 (81.8%) patients who died. Because of this high rate of recurrence, we recommend a thorough assessment of the pelvic area of the patients diagnosed with signet ring cell carcinoma of urinary bladder.
