[Appendicular ureteroplasty to repair a ureteric lesion during disk surgery].

Extensive ureteric lesions raise difficult problems of surgical repair. This is also the case for upper ureteric lesions that often require replacement of the damaged segment or even autologous transplantation. The authors report a case of iatrogenic ureteric lesion resulting in a large defect in a patient operated 6 months previously for an L4-L5 disk hernia, which was treated successfully by interposition of an appendicular graft between the two ureteric stumps.

[Inflammatory myofibroblastic tumours of the bladder].

The inflammatory myofibroblastic tumour of the bladder is a rare benign affection that interests mainly young adults. Its etiopathogeny remains unknown, but its tumoral origin was evocated recently by Griffin (1999), incriminating a chromosomic abnormality involving the ALK gene. We will discuss the etiopathogenic, anatopathological and therapeutical aspects of this lesion for which the diagnosis is histological and the treatment remains conservative with a good prognosis.

[Inflammatory pseudotumors of the kidney. Report of 2 cases].

Inflammatory pseudotumours of the kidney are rare and raise a problem of differential diagnosis with renal cancer. The authors discuss the diagnostic difficulties of this disease in the light of two patients, aged 32 years and 60 years, admitted for left low back pain (2 cases), large kidney (1 case) and haematuria (1 case). The combination of renal ultrasound and CT suggested a renal tumour or a renal cyst, and MRI suggested a necrotic tumour.
