[Oncocytic tumors of the kidney. 11 cases (1978-1987)].

Analysis of this series of cases reveals the following points: complementary investigations (computed tomography, magnetic resonance imaging) sometimes suggest the diagnosis, the oncocytic nature is often a surprise pathological finding, it is difficult to determine whether the lesion is a pure oncocytoma and the exact grade cannot be determined on frozen section, the choice between radical surgery and conservative surgery is made even more difficult, the study of the course of the disease raises the question of whether the term of oncocytoma should not be reserved to low grade tumours.

[Use of the laser in urology].

The usage of laser therapy in urology is based upon thermal effects that lead to tissue destruction by coagulation necrosis and volatilization. The endoscopic treatment of bladder tumors has been its most important utilization. The authors report their experience with 681 bladder tumors in 198 patients and present the technical details of laser therapy, the indications and the results. The recurrence rate at the previously treated tumor area was found to be rather improved: 0.75/100 months/patient for stage pTa and 0.92/100 months/patient for stage pT1. Other utilizations for laser therapy exist: upper tract urothelial tumors mainly in selected cases as solitary kidney; urethral localizations of urothelial tumors and condylomata acuminata; urethral stenosis, as a complement of optical urethrotomy; hemorrhagic cystitis after radiotherapy and some forms of chemotherapy. The pulsed dye laser may become an important advance in endoscopic treatment of ureteral calculi.

[Bladder replacement with colon segments].

The authors report their experience of 81 cases of bladder replacement with colonic grafts between 1980 and 1986. The operative technique is presented and its complications and functional results analysed. Bladder tumors were the most frequent indication although some cases of tuberculosis, bilharziosis and neurogenic bladder were also included. After a critical study of the literature, the authors state that the ileocecal segment has become their preferred material. Over the last fourty months, 42 patients have been treated by the latter form of bladder replacement.

[Apparently isolated tumors of the adrenal gland. Apropos of 12 cases surgically treated].

12 patients with an adrenal tumour were observed in the absence of any known history of neoplasm at the stage of dissemination. In 9 cases the tumour was discovered accidentally. On the basis of the conclusions of the histological analysis following surgical exploration, the authors define the respective advantages of various examinations: laboratory assays, ultrasonography, CT scan, NMR and discuss the management of chance discovery of an adrenal mass.
