[Parapyelic cysts]. / Les kystes para-pyéliques.

Parapyelic cysts present particular characteristics in relation to cystic disease of the kidney. Their intrasinusal development in contact with vascular and canalar elements of the renal hilum explains their often explosive symptomatology and the frequent need for surgical excision of the cyst--procedure difficult to accomplish and nearly always incomplete. Four cases are reported, including 2 with cysts communicating with excretory pathways, and symptoms, signs and diagnostic and therapeutic aspects discussed. Arguments are in favor of an acquired pathogenicity of these cysts (communication with excretory pathways, contingent presence of smooth muscle fibres in the cyst wall).

[Impact of pregnancy on the bladder and urethra. Prospective study]. / Incidence de la grossesse sur la vessie et l'urètre. Etude prospective.

In connection with a prospective study of 200 expectant mothers, the authors discuss the disorders of the lower urinary tract in the course, and at the end, of pregnancy, which are reversible in the vast majority of cases. They also describe the physiopathological mechanisms of lasting sequelae and the precautions to be taken at the time of childbirth in women identified as high-risk vesico-urethral cases.

[Treatment of urethral stenoses by dilatation with the Olbert catheter. A propos of 50 cases]. / Traitement des sténoses urétrales par dilatation à la sonde d'Olbert. A propos de cinquante observations.

The method of treating urethral strictures described in this article is inspired from the technique for percutaneous angioplasty, using an inflatable catheter. It provides good immediate results in 80% of cases, regardless of the localization of the stricture and the previous treatment.

[Obstetric and neonatal consequences of urinary infection during pregnancy]. / Conséquences obstétricales et néonatales de l'infection urinaire gravidique.

In this article, the authors study the real obstetrical and neonatal effects of urinary infection in pregnant women. Basing themselves on 225 cases of gravidic urinary infection, the authors discuss asymptomatic bacteriuria, the need of early diagnosis in risk patients, and the use of regular post-treatment monitoring, in view of the fact that, even when well-treated, this complaint is apt to recur.

[Tumors of the upper urinary tract. Analysis of a series of 85 cases]. / Les tumeurs de la voie excrétrice haute. Analyse d'une série de 85 observations.

Case-reports of 85 patients with upper urinary tract tumors were reviewed. Mainly affected were males (87% of cases), particularly over 60 years of age, the principal presenting sign being hematuria. Other signs such as renal colic, lumbago or infections were observed more rarely. The renal pelvis was affected in 52 of the 85 patients (two of these were bilateral), multiple tumor foci being present in only 6 cases. Most tumors were epitheliomas (62 papillary and 13 non-papillary), with 52 of these at the superficial stage (0 or A), 21 at stage B 1 and 5 at stage B II or C. Based on Broders' classification, 48 were grade II and 16 grade III tumors. Prognosis was routinely poor in 5 patients with a stage B or C tumor and lymph node extension. Diagnosis is by intravenous urography, although retrograde ureteropyelography has its place, with increasing interest being given to ultrasound and computed tomography examinations combined with routine cystoscopy. If no particular contraindications exist, the preferred treatment is a total one-stage nephro-ureterectomy without curettage (52 cases), although curettage was performed at the same time in 9 other patients. Conservative surgery has only a limited application: 6 patients had segmental resections of the ureter and 2 patients underwent tumorectomy. Postoperative mortality was particularly loco: 4 patients (4,7%), mainly from vascular or respiratory diseases. (4,7%), mainly from vascular or respiratory diseases. Bone (5 cases), pulmonary (3 cases) and medullary (1 case) metastases represented the main cause of death during the year following surgery, all these patients having infiltrating tumors.(ABSTRACT TRUNCATED AT 250 WORDS)
