HLA-A and B antigens in patients with Peyronie disease

Using microdroplet lymphocyte cytotoxicity test, as a method of HLA typing, 9 patients with Peyronie disease were studied from a viewpoint of relationship between this disease and HLA-A and B antigens. The frequencies of each antigen in the patients were compared with those of healthy controls. No significant difference of distribution in HLA antigens was observed between the patients and the control group.

Electron microscopic study of acuteretrograde pyelonephritis in mice

Abstract A strain of Escherichia coli 06:H-, which was isolated from a patient with acutepyelonephritis, was used to produce ascending pyelonephritis in mice. The histologic features at the early stage of acute pyelonephritis and the pathways of bacterial invasion and distribution in the infected kidneys were studied by using transmission electron microscope. The histologic changes were characterized by degeneration and destruction of renal pelvic and tubular epithelial cells, and a massive infiltration of polymorphonuclear leukocytes. Bacteria invaded the pelvic surface and spread over the renal medulla and cortex by contiguity twelve hours after infection. It was also shown that bacteria ascended the tubules, multiplied in the tubular lamina, destroyed the tubular epithelial cells, and spread over the renal cortex by twelve hours. In addition, bacteria and leukocytes phagocytizing bacteria were present in the capillaries in the renal interstitium twelve hours after infection.

Malakoplakia of urinary bladder following cadaveric renal transplantation.

Malakoplakia of the urinary bladder following cadaveric renal transplantation in a twenty-two-year-old woman is reported. Urinary tract infection with Escherichia coli persisted postoperatively. Three years later, gross hematuria and fever occurred. Yellow-tan mucosal plaques or nodules were observed cystoscopically, and histologic examination revealed malakoplakia of the urinary bladder with characteristic foamy histiocytes containing Michaelis-Gutmann bodies.

Endourological Re-Establishment of a Disrupted Infundibulum after Renal Laceration

We report a case of severe urinary extravasation after renal contusion and its successful management by endoscopic creation of a neoinfundibulum. When the stenotic infundibulum cannot be traversed with a guide wire, creation of a new infundibulum will offer a secure alternative for accessing the collecting system.
