[Value of urgent ultrasonography after renal injuries. A report on 12 cases (author's transl)].

The results of ultrasonography recordings carried out urgently in 12 patients after renal trauma are used by the authors as a basis for outlining the ultrasonography features discovered in post-traumatic renal lesions, and for discussing the value and place of this examination in overall investigations of these lesions. Ultrasonography findings are compared with those of intravenous urography, and in certain cases with those of arteriography. Ultrasonography appears to be indispensable in many cases in order to confirm intravenous urography results, to complement them, and possibly to make up for their deficiencies. It is of particular value in 2 conditions: a) renal artery thrombosis, in which case it is the only examination capable of supplying information on the parenchyma, b) benign renal contusions which may not appear on intravenous urography.

[The "double J" endo-ureteral prosthesis. Experience apropos of 21 cases].

Following Finney's work on the subject, the authors propose an endo-ureteral diversion using the new double J ureteral catheter stent. In the light of their experience of 21 cases, the authors stress the speed and simplicity of this very minor operation, and propose wider indications.

[Ureteral metastases from prostatic cancers. 2 cases. Review of the literature].

The authors report two new observations of ureteral metastases from prostatic cancers and review the 17 already published cases. The relative rarity might well be only apparent, in relation with the delay in the exploration of the first observations. The diagnostic criteria are less clinical and radiological than anatomo-pathological, the metastases contrasting themselves with ureteral invasion by direct propagation. The anatomical status shows no predominance between tumoral or infiltrating forms, nor of any particular site on the ureter, while noting a relative frequence of bilateral involvement. The therapeutic approach is dependant upon these factors. The prognostic is reserved, at the cost of a segmental ureteral resection or a nephro-ureterectomy.

High incidence of chronic graft versus host disease after allogeneic peripheral blood progenitor cell transplantation. The Spanish Group of Allo-PBPCT.

BACKGROUND AND OBJECTIVE: The incidence of acute GVHD (aGVHD) in allogeneic peripheral blood progenitor cell transplantation (allo-PBPCT) seems to be similar to that seen in allogeneic bone marrow transplantation (allo-BMT). In contrast, some preliminary results suggest that the incidence of chronic GVHD (cGVHD) might be higher. The aim of the present study was to analyze the actuarial probability of developing cGVHD in allo-PBPCT, its clinical manifestations and response to treatment. METHODS: We have retrospectively analyzed clinical results from 21 allo-PBPCT recipients that had been transplanted at least 18 months before this study and that fulfilled the following criteria: HLA identical sibling donor, non T-cell depleted apheresis and more than 90 days of survival with sustained engraftment. The median follow-up was 12 months (range 4.5-22). RESULTS: Twelve out of the 21 (57%) patients presented cGVHD, 1 limited and 11 extensive. The actuarial probability of cGVHD was 72.7% (95% CI, 49-96%). The median interval from transplant to onset was 180 days (range 95-270). Nine of the 12 cases (75%) presented combined skin and liver involvement. Of the other three, the liver was involved in one case; skin, mouth, and nail cGVHD was observed in another case; and skin and mouth involvement together with an obstructive pulmonary disease was observed in the remaining case. Under therapy, a complete resolution of cGVHD manifestations was achieved in five cases, and a partial improvement was attained in three other cases. In two responsive patients, cGVHD reappeared after stopping treatment. Four patients were refractory to the treatment. INTERPRETATION AND CONCLUSIONS: It would appear from this retrospective and multicenter study that, after a median follow-up of 12 months, cGVHD after allo-PBPCT could be more frequent than after allo-BMT. A randomized trial with a large number of patients and a sufficient follow-up will be necessary to answer this question definitively.
