Analysis of bladder carcinoma by subsite. Cystoscopic location may have prognostic value.

Nine hundred fourteen cases of carcinoma of the urinary bladder registered from 1977 to 1988 with the Kansas state tumor registry were evaluated by subsite for differences in grade, histology, sex, age at diagnosis, and survival. Only initial occurrences of carcinoma were included. Carcinoma of the lateral walls accounted for 37.1%; the posterior wall, 17.9%; the trigone, 12.6%; the neck, 11.1%; the ureteric orifices, 9.8%; the dome, 7.7%; and the anterior wall, 3.8%. Malignant neoplasms occurring in the neck of the bladder had a significantly poorer prognosis by survival analysis (P less than 0.05). Malignancies of the dome were found to present as higher grade lesions (P = 0.00003), and carcinoma of the ureteric orifices and lateral walls tended to be of lower grade (P = 0.02 and P = 0.05, respectively). Carcinomas of the anterior wall and dome occurred in a more elderly population (mean ages, 75.6 and 73.9 years, respectively), and carcinomas of the trigone and ureteric orifices occurred in a younger group (mean ages, 68.3 and 67.5 years, respectively). On histologic evaluation the trigone gave rise to more squamous cell carcinoma than expected (P = 0.001, 325% of expected). No distribution difference was noted among subsites with respect to sex. These data show significant differences among subsites of the urinary bladder with regard to survival, grade, histology, and age at diagnosis.

The significance of age on symptoms and urodynamic- and cystoscopic findings in benign prostatic hypertrophy.

To evaluate influence of age on symptomatology and objective parameters in benign prostatic hypertrophy, preoperative findings in 199 unselected patients during one year were analysed. Symptoms of bladder instability increased with age, as did incidence of uninhibited detrusor contractions and bladder trabeculation, whereas maximum urine flow and obstructive complaints decreased, although prostatic size was the same. In the oldest age groups only was increasing prostatic size associated with increasing bladder trabeculation. Age related changes in neurological control and in the structure of the bladder may be involved, and the present results suggest age to be an important factor in the interpretation of symptoms and objective findings in prostatic hypertrophy.

Cystoscopic confirmation of inadvertent ureteral catheterization during cystometry.

A patient in whom the right ureter was inadvertently catheterized at the time of cystometry is described. Upon filling, the patient immediately developed severe colicky right flank pain and the vesical pressure of 150 cmH(2)O triggered the pump's automatic shut-off mechanism. Cystoscopy was performed and confirmed the inadvertent placement of the microtip catheter in the right ureteral orifice. After the catheter was repositioned, symptoms resolved and the remainder of the examination was performed routinely, with normal vesical and urethral pressures.

Cystoscopic and DMSA findings in relation to types of reflux demonstrated on percutaneous direct radionuclide cystography in children.

BACKGROUND: The new technique of percutaneous direct radionuclide cystography (PDRC) allows the accurate demonstration of vesicorenal reflux under physiological conditions during resting and micturition phases. Five types of reflux have been described, the clinical relevance of which is uncertain. OBJECTIVE: To determine whether a relationship exists between the type of reflux identified on PDRC and the appearance of the ureteric orifice at cystoscopy or the prevalence of renal abnormalities. MATERIALS AND METHODS: The reports of 281 PDRC examinations were reviewed and 76 children with reflux formed the population of this study. Studies of these children were reviewed to classify the reflux as types 1-5, and patient records were searched for cystoscopy and DMSA scan reports. RESULTS: Regardless of the type of reflux, the ureteric orifices were found to be open at cystoscopy in 60-66% of refluxing units. DMSA scan abnormalities were present in 68% of units with reflux at rest, 61% of units with reflux on micturition and 86% of units with reflux on both resting and micturition phases. In comparison with contralateral units that did not reflux, the presence of reflux had a significant association with openness of the ureteric orifice ( p<0.00001) and DMSA abnormality ( p<0.005). CONCLUSIONS: Reflux of any type is strongly associated with an open ureteric orifice. Units that reflux during both resting and micturition phases had a higher incidence of DMSA abnormality than those refluxing during one phase only, but this was not statistically significant.
