[The concept of renal dysplasia. Apropos of 67 cases].

The aim of this study, based upon 130 nephrectomies in children, was to emphasise the importance of congenital lesions in comparison with inflammatory lesions. In the context of congenital abnormalities, the abundance of our material made it possible for us to review our anatomical findings in the context of clinical and radiological data. This had led us to propose an anatomical classification of renal dysplasias. Although overlap cases exist, this classification into four separate entities according to the nature and extent of the histological and topographical lesions is satisfactory by virtue of its clarity. It is an agreement with the most recent publications of authors interested in the vast problem of renal malformations.

[Ultrastructural, histochemical and histological study of bladder pheochromocytoma].

In the rarely occuring vesical location the pheochromocytoma shows the usual features as well from morphological (conventional and ultrastructural) as from histochemical point of view. Biochemical examinations confirm the amount of adrenalin and noradrenalin. In connection with this case the authors discuss the problems related to the histogenesis of vesical pheochromocytomas and consider the linking up of this type of tumors to the APUD system.

[Endo-surgical dissection of the upper urinary tract through the retroperitoneal and transperitoneal route: an experimental study with pigs and cadavers].

In order to define the best method for endosurgical dissection of the upper urinary tract, an experimental study comparing the retroperitoneal and transperitoneal approaches was performed. Between September 1991 and February 1992, 15 female pigs and 8 human cadavres underwent endosurgical dissection of the upper urinary tract. The retroperitoneal approach was used in 8 pigs and 5 cadavres. In the lateral supine position, the retroperitoneum was insufflated at the lower pole of the kidney, via a 2 cm cutaneo-muscular incision, followed by a blind dissection with the finger to create a space in the retroperitoneal fat. Four trocars were inserted into the retroperitoneal space allowing dissection of the ureter, kidney and its vascular pedicle. The renal vessels and the ureter were then clipped or stapled with the endo-GIA then sectioned. The operation was successfully performed in all of the pigs with a mean operating time of 2 hours. Complications were limited to two peritoneal effractions. Retroperitoneal endosurgical dissection was much longer and more difficult to perform on the cadavre (mean operating time: 3 hours). Satisfactory retropneumoperitoneum was never able to be obtained due to the large amount of retroperitoneal fat and the proximity of the twelfth rib and posterior iliac crest interfered with the insertion of the trocars and made dissection more difficult. The transperitoneal approach was performed in 7 pigs and three cadavres. In the lateral supine position, after creating pneumoperitoneum using a Veress needle, 4 trocars were inserted into the peritoneal cavity. Toldt's fascia was gripped and incised allowing retraction of the colon towards the midline, thereby exposing the renal region. The ureter and the renal vessels were dissected. The renal artery and vein were then clipped or stapled with the endo-GIA then sectioned, while the ureter was clipped and sectioned. The complications of the transperitoneal route were: an injury to the small intestine during insertion of a trocar and haemorrhage due to accidental section of a lower pole renal artery, which was able to be controlled by application of clips. In the pig, the transperitoneal approach was as simple to perform as the retroperitoneal approach and the mean operating time was the same (two hours).(ABSTRACT TRUNCATED AT 400 WORDS)

[Scrotal trauma. Report of 33 cases].

We report a serial case study of 33 patients from May 1980 to November 1990 presenting a scrotal contusion. In 2/3 of cases, the physical examination showed a scrotal oedema or an hematocele. Ultrasonography showed a testicular injury while clinical examination was subnormal in 2 patients. In the other cases, ultrasonography showed an hematocele without asserting in all cases the traumatic rupture of the tunica albuginea. 27 patients have been surgically explored: 14 ruptures of the testicle, 3 intratesticular haematoma, 3 scrotal open traumatic injuries, and 7 extratesticular haematoma. Only 3 orchidectomies were required for the 6 patients who have not been explored surgically, the testis was normal at one month. The follow-up of these young patients is difficult, 11 had been seen again at 1 month. At long term follow-up, three patients had been seen at 1, 3 or 6 years without testicular after-effects.

[A cause of neonatal respiratory distress: cerebral tissue heterotopia in the cavum].

BACKGROUND: Brain heterotopia can be reflected in disturbances of the oropharynx during the neonatal period, such as acute upper airway obstruction. The main differential diagnosis is encephalocele, which must be recognized before undertaking any surgical procedure. CASE REPORT: A boy, aged 5 days, with a cleft palate and bifid uvula, was admitted for respiratory distress. The distress initially occurred during bottle-feeding, but later became permanent. A solid mass, seemingly implanted in the superior wall of the pharynx, was successfully removed by forceps. A later CT scan showed the absence of any defect in the cribriform plate, thus excluding diagnosis of encephalocele. Histological, examination of the mass showed glial tissue without neurons. CONCLUSION: The presence of a pharyngeal mass in a newborn signals three possibilities: teratoma, heterotopic brain tissue or encephalocele. Encephalocele must by ruled out by a preoperative CT scan with a water soluble contrast agent in order to avoid CSF leakage and meningitis. Respiratory distress should be treated by oral endotracheal intubation to allow time for CT scan investigation.

[Ambulatory urologic surgery].

Outpatient urinary tract surgery has been possible in our department since November 1988. In this programme, surgical procedures are performed in patients who do not remain in hospital overnight. Stringent surgical, medical and social criteria are prerequisites to this kind of surgery. Between November 1988 and October 1990, 260 outpatients have been admitted in our department to undergo endoscopic surgery (110 cases), conventional surgery (110 cases), extracorporeal lithotripsy (44 cases) or various types of exploration, local drug perfusions and change or removal of stents (37 cases). Thirty six patients stayed in the inpatient department for the first night. One patient was readmitted the day after his discharge because of clotting after bladder biopsies. At the end of this first experience, ambulatory surgery of the urinary tract has proved to be safe for the patients and to offer many advantages on economical, psychological and medical grounds. It can be predicted that in the future the number of outpatient procedures will increase dramatically.

[Renal oncocytomas (author's transl)].

The authors report their experience of a rare tumor of kidney : oncocytoma. This tumor was made of polygonal cells separated by an endocrinoid stroma. They report pathological feature and clinical course and pronostic who is better than in carcinoma. Other names have been given : proximal tubular adenomas, true kidney hypernephroma, Riopelle tumor.

[Urinary incontinence. Indications and results of hydraulic sphincter prosthesis].

An AMS 800 sphincteral prosthesis was implanted in 20 patients (18 men and 2 women) with total urinary incontinence, with results that were superior to those of the previously used procedures: success in 18 cases (90%), failure in 2 cases (1 incontinence, 1 explantation). A change of material was necessary in 3 patients. The AMS 800 prosthesis constitutes a major advance in the treatment of iatrogenic (post-prostatectomy) incontinence in man, of recurrent stress incontinence in women and of some cases of neurogenic or malformative urinary incontinence.

[Lymphography and fine needle puncture biopsy in the evaluation of lymph node involvement. Apropos of 207 cases].

Percutaneous fine needle puncture biopsy was performed on lymph nodes taking up contrast during lymphography in 207 patients with various disorders: urogenital (174 cases), gynecologic (13 cases), hematologic (17), others (3). At the present time, in fact, and simultaneously with the development of physical methods of diagnostic exploration (ultrasonography, computed tomography) needle puncture biopsy has become of increasing importance to confirm a suspected diagnosis. Needle puncture biopsy under television control is a simple, painless and practically nontraumatic procedure. When performed under precise conditions and a strict methodology (routine sampling as a function of the primary glandular chains), it establishes the correct diagnosis in a large number of lymphographies, enabling a rapid and more precise evaluation of the degree of extension and thus a better therapeutic choice.
