Urinary release of 72 and 92 kDa gelatinases, TIMPs, N-GAL and conventional prognostic factors in urothelial carcinomas.

Objectives: A urinary release of gelatinases A and B matrix metalloproteinases-2, -9 (MMP-2, -9), and tissue inhibitors (TIMP-1, -2) occurs during normal epithelial turnover. A proteinase increase, reduced inhibitors or both potentially account for cell mobility and bladder cancer progression. In order to define normal levels and thresholds for transitional cell carcinoma (TCC) patients, urinary gelatinases, tissue inhibitors and neutrophil-gelatinase-associated lipocalin (N-GAL) were investigated for end-point clinical status and compared with normal subjects during a 2-year follow-up prospective study.

[Puerperal thrombophlebitis of the ovarian vein revealed by renal colic].

The authors report the clinical case of a young woman with thrombophlebitis of the right ovarian vein following delivery by caesarean section, initially presenting in the form of renal colic. In the light of a review of the literature, they recall the pathophysiological mechanisms of ovarian thrombophlebitis and the various features observed on imaging examinations. The most frequent clinical features are also described.

Ureteroileal implantation in orthotopic neobladder with the Le Duc-Camey mucosal-through technique: risk of stenosis and long-term follow-up.

Purpose: We determined the postoperative risk of nonneoplastic ureteroileal implantation stenosis using the Le Duc-Camey technique, and assessed the extent to which followup is mandatory.

Materials And Methods: Between October 1980 and October 1989, after a cystoprostatectomy, 158 consecutive men underwent lower urinary tract reconstruction by means of a U-shaped orthotopic ileal neobladder. Of these cases 109 were tubularized and 49 were detubularized.

Original oblique sections of the retroperitoneum: radio-anatomic basis.

The authors present oblique sections of the retroperitoneum adapted to the morphology of each patient, which affects both the liver and the organisation of the retroperitoneum. This original method involve two incidences for studying the left and right retroperitoneum separately with vertical sectional planes. The authors postulate that the orientation of the retroperitoneal viscera depends on the degree of hepatic development, so these incidences are chosen with reference to axial sections of the portal bifurcation and the middle hepatic v.

Pseudoneoplastic xanthogranulomatous pyelonephritis. A typical clinical presentation but unusual diagnosis and treatment.

Xanthogranulomatous pyelonephritis is a rare disease that may mimic various renal lesions, especially renal tumors, in its focal form. We report a case of pseudoneoplastic xanthogranulomatous pyelonephritis in a young woman. This case is unusual, because it was diagnosed by a percutaneous renal puncture and furthermore total renal recovery was achieved by antibiotic treatment alone.
