Unusual gas pattern in emphysematous cystitis: a case report.

We present a case of emphysematous cystitis in a 43-year-old female. The gas pattern was unusual because there was only gas accumulation in the urinary bladder without bladder wall thickening or intramural gas formation. The differential diagnosis included postoperative states, enterovesical fistula, and iatrogenic instrumentation. The prognosis of emphysematous cystitis is good after early diagnosis and prompt treatment with appropriate antibiotics, blood glucose control, and adequate urinary drainage. The patient was discharged on hospital day 5 with one additional week of oral antibiotic therapy. She was quite well at the time of writing and her diabetes was controlled with an oral hypoglycemic agent.

Foreign body stone in the urinary bladder: a case report.

Bladder calculi rarely form spontaneously and are usually a manifestation of an underlying pathologic condition of the lower urinary tract, including voiding dysfunction, urinary infection, obstruction, or foreign body retention. However, a ruptured Foley balloon-induced bladder stone is an unusual complication of an indwelling Foley catheter. We report a case of spinal cord injury with paraplegia and bladder stone induced by a fragment of a ruptured Foley balloon. The bladder stone and the Foley balloon fragment were successfully removed by cystoscopy. The stone was composed of calcium oxalate and calcium phosphate. We report this unusual case to raise awareness that it is important to check the integrity of the Foley catheter after removal of the tube.

Laparoscopic bladder diverticulectomy for large bladder diveticulum: a case report.

Bladder diverticula are herniations of the bladder mucosa through the bladder wall musculature. Acquired bladder diverticula are the result of outlet obstruction, mostly benign prostate enlargement, infections, or urethral stricture. Traditionally, bladder diverticulum was excised by the open method. However, the laparoscopic technique has been widely used to treat many urologic diseases, including bladder diverticulum. Laparoscopic diverticulectomy can be performed transperitoneally or extraperitoneally. We report our initial experience with laparoscopic transperitoneal diverticulectomy for a large bladder diverticulum caused by bladder outlet obstruction. The patient had satisfactory micturition and was discharged on the eighth postoperative day.

Transitional cell carcinoma of the renal pelvis with extension into the inferior vena cava: a report of two cases.

Of all primary malignant renal tumors, 10% to 15% originate from the renal pelvis, and 90% to 92% of these tumors are transitional cell carcinomas. Nonetheless, renal pelvis transitional cell carcinoma extending into the inferior vena cava is very rare. We report one confirmed case and one highly suspicious case of renal pelvis transitional cell carcinoma with a tumor thrombus in the inferior vena cava. Both of our patients died within 6 months of initial diagnosis, indicating the poor prognosis and advanced stage of transitional cell carcinoma with an inferior vena cava thrombus. Transitional cell carcinoma should be considered in patients with obstruction of the renal vein and the inferior vena cava.
