[The treatment of patients with ureteral calculi by ureteroscopy and intracorporeal lithotripsy].

Ureteroscopy with endocorporeal urinary stone lithotripsy (EUSL) implies an "in situ" stone fragmentation including or not a basket extraction of the fragments. EUSL needs three conditions: ureteronephroscopy (antegrade or retrograde), sources of energy (ultrasonic, electrohydraulic, laser), extraction devices (basket, grasping forceps). The paper reports the data on 120 ureteral stones treated by ureteroscopy and laser lithotripsy with an overall effect of 84%.

[Carcinoma in situ of the bladder. Apropos of 10 cases].

10 cases of primary carcinoma in situ are described and the symptomatology of the disease is analysed. The role of cytodiagnosis is emphasised. The evolution is variable. In 2 cases the bladder became totally retracted and total cystectomy had to be performed in spite of the fact that the lesion remained intra-urothelial. Invasive cancer developped only in 2 cases: 7 and 6 years after diagnosis. Conservative treatment by Tur seems logical whilst the carcinoma remains strictly "in situ".

[Chronic lymphocytic leukemia and cystadenocarcinoma of the kidney. A report of one case (author's transl)].

The association between chronic lymphocytic leukemia and a solid tumor is well known. When the leukemia appears before the tumor a question may be asked : is the tumor a cancer or a localisation of the leukemia ? When the cancer is diagnosed before the leukemia, an other question may be asked : is it a true leukemia or is it a paraneoplasic leukemoid reaction ?
