[Unusual tumors of the testis. Apropos of 22 cases].

The authors report their experience of rare non-germ-cell tumours of the testis over a period of 10 years. The criteria of benign disease, justifying testicular preservation in 5 out of 7 cases of epidermoid cysts, are defined. Four cases of Leydig cell tumours, including 3 with gynaecomastia, are described. Three cases of adenomatoid tumours with conservative surgery, 3 lymphomas, 2 mature teratomas and 2 cysts of the rete testis are also reported. The place of ultrasonography is defined and the possibility of conservative surgery is discussed in relation to a review of the recent literature.

[Endoscopic transvesicoparietal exteriorization of ureteral catheters].

Endoscopic introduction of catheter into the ureter for drainage has long been a common procedure, and recent advances in endoscopic urology have widened its indications. The ureteral catheter is usually exteriorized through the urethra and attached to the urethral catheter, but with this technique it tends to descend spontaneously and to create infections which are a possible cause of ureteral stenosis. A technique of endoscopic transvesicoparietal exteriorization of ureteral catheters without incision has been developed in 1982. The problems encountered in exteriorizing the ureteral catheter through the lumen of a suprapubic trocar have now been solved by using a bipodal forceps introduced into the trocar.

[Tumor grafts in the upper urinary tract secondary to tumors of the bladder epithelium].

A retrospective study of cases seen between 1975 and 1985 showed 24 tumors of upper urinary tract secondary to primary bladder localizations. These secondary localizations developed during evolution of multi-resected recurring bladder tumors, within a mean period of 15 months after discovery of a secondary vesicorenal reflux. This reflux is acquired constantly during the course of these tumors and it is undoubtedly responsible for the onset of these upper tract tumoral grafts. These findings suggest the need for urographic surveillance combined with regular endoscopic examinations of patients with bladder tumors, for prevention of reflux during endoscopic resections and for treatment of any reflux detected.

[Benign prostatic hypertrophy. Surgical treatment. Value of surgery by a high approach].

Transurethral resection of the prostate is not a new procedure for the treatment of adenoma of the prostate but is being increasingly used. This fact is incontrovertible and all urologists perform transurethral resection for small adenomas. For large adenomas we still believe surgical removal is the best method. The results of resections of the prostate reported in the literature are not good enough to cause us to change our mind (80% good results after one or several procedures with an 8% incontinence rate!). To allow a more accurate evaluation we compared our personal results with surgical removal to the results of resections performed in our unit and reported in the literature.

[Treatment and course of advanced bladder cancers. Retrospective study of 29 cases].

A retrospective study of 29 patients with extensive but non metastatic bladder cancer (T234N+ M0) demonstrated once more the dreadful prognosis of advanced bladder cancer. Only 4 patients are alive without evidence of recurrence with a follow up of 12 to 64 months. The 11 patients whose tumor was too extended for radical cystectomy had a similar survival rate and better quality of survival than the 18 patients who underwent total cystectomy. Recurrence appears quickly (mean time : 11 months) and is mostly metastatic. This study led us to change our therapeutic attitude. We now use systemic preoperative polychemotherapy and we no longer perform radical cystectomy in bulky nodal metastasis.

[Extensive nephrectomy in severe forms of cancer of the kidney in the adult].

Resection of renal tumours may be useless when the staging procedures reveal that the disease is too far advanced. A retrospective study of 100 radical nephrectomies for renal cell carcinoma distinguished the following groups: advanced cancers in young patients; cancers in patients over the age of 70 years. Despite the limited follow-up of this series, the study of survival demonstrates the following points: the difficulty of predicting the degree of lymph node involvement on pre-operative staging, the value of an anterior sub-costal and abdominal approach which facilitates radical nephrectomy in elderly and fragile patients, the poor prognosis of lymph node invasion and metastases, although some patients have survived for 12 months after resection of metastatic tumours.
