Bladder wall calcification after topical mitomycin C.
We report a case of calcification in the wall of the bladder following treatment of transitional cell carcinoma of the bladder with intravesical mitomycin C.
Acute lobular nephronia.
Acute lobular nephronia is an unusual form of localized renal infection, which has a characteristic computerized tomographic and ultrasonographic appearance, and should be distinguished from abscess or other renal masses. Treatment is nonoperative, consisting of intensive antibiotic therapy.
Non-opaque calculus demonstrated by computerized tomography.
Computerized tomography demonstrated that a non-opaque filling defect within the ureter of a ureterostomy patient was a struvite calculus containing a minimal amount of calcium salts.
Computed tomography of the retroperitoneum following nephrectomy.
Twenty-five patients were examined by computed tomography (CT) after nephrectomy. CT was useful in the detection of postoperative complications and local recurrence of tumor. Ultrasound was difficult because of rib artifacts or bowel gas, and a fluid-filled bowel often simulated tumor: oral contrast material was useful during CT. Local recurrence was demonstrated by CT in 8 patients in whom it was clinically suspected. Recurrent tumor was simulated by scarring in 3 cases and by an accessory or residual spleen in 2. Operative complications included one hematoma and one retroperitoneal abscess. CT could be useful in following up selected patients after nephrectomy.
