    Notes: Résumé Le rôle du système nerveux autonome dans la physiologie de l'uretère est un sujet controversé. L'étude histochimique des catécholamines fluorescentes et de l'acétylcholinestérase démontre l'existence d'une riche innervation adrénergique et cholinergique de l'uretère humain et animal. Cette innervation se caractérise par la présence de fibres nerveuses terminales et de ganglions mixtes (adrénergiques et cholinergiques), situés dans la partie terminale de l'uretère. L'étude ultrastructurale de l'innervation de l'uretère confirme l'existence d'axones adrénergiques et cholinergiques. Les deux types d'axones forment des varicosités préterminales et terminales tout le long de leur trajet. L'existence de fibres nerveuses adrénergiques est confirmée par l'utilisation de 5-hydroxydopamine, un ≪faux≫ transmetteur sympathique permettant leur indentification sélective. Les deux types d'axones sont observés dans un même filet nerveux en étroite relation l'un avec l'autre, suggérant une interaction possible entre composante adrénergique et cholinergique dans l'uretère. Les terminaisons cholinergiques sont considérées comme étant des récepteurs sensoriels. Des terminaisons purinergiques utilisant les nucléotides cycliques comme transmetteurs s'observent également dans la musculature et la sous-muqueuse urétérale. Un modèle de l'innervation de l'uretère est proposé à la lumière de ces résultats ultrastructuraux; il prend en considération particulière les étroites et nombreuses connexions intermusculaires et d'autre part la rareté des contacts neuromusculaires étroits. Ce modèle considère le péristaltisme urétéral comme un phénomène essentiellement myogène, l'influence du système nerveux autonome étant secondaire, susceptible de jouer un rôle dans la régulation de cette activité spontanée en influençant la tonicité urétérale. Les ganglions urétérovésicaux représentent des ≪neurones adrénergiques courts≫ puisqu'ils dérivent de ganglions sympathiques situés dans l'organe innervé, et ce par opposition à la conception classique du système nerveux autonome. L'étude en microscopie électronique précise l'ultrastructure des ganglions urétérovésicaux. Elle souligne l'existence de structures adrénergiques représentées par des terminaisons nerveuses adrénergiques et des petites cellules riches en catécholamines. Ces structures sont susceptibles de moduler l'activité ganglionnaire pour intégrer la fonction de l'uretère et de la vessie.

    Description / Table of Contents: Zusammenfassung Zur Beurteilung einer zweimal täglichen Dosierung von Bacampicillin wurde bei 49 Patienten mit Infektionen der oberen oder unteren Harnwege eine Therapie mit entweder 600 mg Bacampicillin, zweimal täglich, oder 500 mg Amoxycillin, dreimal täglich, über mindestens sechs Tage durchgeführt. Ungefähr ein Drittel der Patienten jeder Gruppe hatte verschiedene Komplikationen, wie man sie routinemäßig in einer urologischen Klinik sieht. Die Kontrolle nach der Behandlung ergab für beide Präparate ein ähnliches Therapieresultat: unter Bacampicillin wurden die Bakterien bei 23 von 24 Patienten, unter Amoxycillin bei 17 von 21 Patienten eliminiert. Als Nebenwirkungen traten hauptsächlich gastrointestinale Beschwerden auf. Sie waren bei der Behandlung mit Amoxycillin signifikant häufiger (29.1%) als mit Bacampicillin (7,6%) (p=0,05).
    Notes: Summary To evaluate a twice daily dosage of bacampicillin, 49 patients with upper or lower urinary tract infections were given bacampicillin, 600 mg twice daily, or amoxycillin, 500 mg three times daily, for at least six days. About one third of the patients in each group had various complications usually seen at a urological clinic. The therapeutic results were similar with both drugs at follow-up after treatment, i. e. the bacteria were eliminated in 23/24 patients on bacampicillin and 17/21 on amoxycillin. Adverse reactions, the majority gastrointestinal, were significantly more common (p=0.05) with amoxycillin (29.1%) than with bacampicillin (7.6%).

    Notes: Summary Renal pseudotumors will simulate a neoplasm on urography but are histologically composed of normal tissue. Pseudotumoral lesions of the kidney are usually discovered on urography and simulate a neoplasm, but are histologically composed of normal tissue. Various conditions such as foetal lobulation, hypertrophy of the columns of Bertin or large cloisons, nodular compensatory hypertrophy, renal sinus lipomatosis, and compression by blood vessels may simulate tumors of the kidney. It is therefore of the utmost importance to make a clear-cut diagnosis with the help of echography, CT-scan, and in some cases, arteriography.

    Notes: Summary Treatment of hypernephroma presenting with atria-caval involvement without distant metastases is a surgical challenge. The procedures used in three different cases are described. In one case the caval thrombus extending into the atria-caval junction was delivered during clamping of the atrium without cardiovascular bypass. In another case the remaining atrial thrombus was removed in a second session with cardiovascular bypass. For the third case cardiac bypass was established immediately to permit safe and complete removal of the atria-caval thrombus. In order to plan the surgical procedure adequately, it appears essential to determine exactly the upper level of the thrombus. In cases with atrial involvement, cardiovascular bypass is advisable to perform radical surgery under the safest conditions.

    Notes: Summary Based on a report of 16 patients, the authors describe and evaluate the sonographic aspects of renal inflammatory diseases (RID) in children. In acute disease, thickening of the renal pelvic wall as evidence of pyelitis was the most common pattern demonstrated. Increased renal volume, nontumoral parenchymal area of hyperechnogenicity, abscess-type mass or calcified solid mass (in the case of xanthogranulomatous pyelonephritis) were other aspects encountered. Related findings included evidence of chronic pyelonephritis (cortical thinning) and of renal malformations. In patients with RID, the role of ultrasound is doubly important. While it is being employed increasingly as a screening test, it is most useful as a follow-up technique to detect complications and assess renal growth. Nevertheless, it should be stressed that ultrasound may be totally normal in cases of RID and complementary examinations (IVP, VCUG and nuclear scanning) are still necessary.

    Neonatal congenital megaureters: trends in diagnosis and management (1992)

    Notes: Summary This report describes the last 16 cases of congenital primary obstructive megaureter (CPOM) encountered at our institution, whereby antenatal diagnosis was an important method of detection (13 of 16 cases). In most cases, no precise diagnosis was established in utero (2 of 13 infants). This lack of accuracy is of little importance, since all babies with suspected uropathies undergo a uroradiological work-up after birth (ultrasound, voiding cystogram, and urogram). Our series showed a marked male predominance (80%). CPOM showed a high potential for spontaneous resolution after birth (40%). Therapeutic decisions should be based mainly on studies of renal function (quantitative isotopic nephrogram with diuretics). Therefore, as long as renal function has not deteriorated during follow-up, conservative management should be elected first. Only cases showing clinical symptoms or decreased renal function should be treated surgically.

    Notes: Summary Erectile impotence may be due to psychological problems, neurogenic dysfunction, hormonal alterations or compromised penile blood flow. With a better understanding of the erectile mechanism and with the development of new investigative techniques, recognition of the origin of impotence has dramatically improved in recent years, indicating that the majority of these patients are impotent due to vascular abnormalities. Rather than discussing the physiology of erection and its problems, we wish to propose a rational approach to the diagnosis and treatment of vasculogenic impotence.

    Notes: Summary A total of 62 patients with benign prostatic hypertrophy (BPH) were treated in one single session with a second-generation hyperthermic device using the transurethral approach. Before the treatment and at each month thereafter, we evaluated the volume of the prostate by transrectal ultrasound, the urinary flow, the amount of residual urine and the prostatic specific antigen (PSA) level. There was a 2-fold increase in PSA levels at 1 day after treatment, but the values returned to normal after 1 month. No change in prostatic volume was observed. Among a group of 17 patients showing retention, 8 who were discharged without a catheter at 1 week after treatment showed minimal residue and acceptable flow. In all, 39 patients were evaluable after a 2- to 4-month follow-up. At 2 months of follow-up, 77% of the evaluable patients showed subjective improvement and 45% exhibited objective signs of improvement. Obvious pathological modifications were observed in 7/8 patients who underwent an open retropubic prostatectomy after hyperthermia treatment. Histology revealed areas of focal glandular necrosis around the preserved urethra, suggesting a possible diminution of urethral resistance to bladder outflow. Minimal side effects were encountered that did not limit the treatment. A long-term follow-up period is mandatory for better definition of the indications and limits of this new technique.

    Description / Table of Contents: Résumé Sur 241 transplantations rénales avec reconstruction de l'arbre urinaire par implantation urétéro-vésicale, 108 ont été faites selon la technique endovésicale de Politano-Leadbetter (P.L.), 133 selon la technique extravésicale de Grégoir-Lich (Gr.L). Les complications observées ont été: 11 fistules urinaires, 10 (9.3%) après P.L., 1 (0.8%) après Gr.L. (P〈0.01) 12 sténoses, 3 (2.8%) après P.L., 9 (6.8%) après Gr. L. (P〉0.10). Aucune de ces complications urologiques n'a entraÎné de décès ni d'échec de la transplantation. La technique de Grégoir-Lich évite donc la complication urologique la plus grave de la transplantation rénale, la fistule urinaire.
    Notes: Abstract Among 241 renal transplants with implantation of the ureter into the urinary bladder, the endovesical technique of Politano and Leadbetter (PL) was used in 108 cases and the extravesical technique of Grégoir and Lieh (GrL) was used in 133. Urinary fistulas occurred in 10 patients (9.3%) with the PL technique and in only 1 patient (0.8%) with the GrL technique. The difference was highly significant (p〈0.01). Stenosis of the ureter developed in 3 patients (2.8%) following the PL technique and in 9 patients (6.8%) after the GrL technique, an insignificant difference (p〉0.10). None of the complications resulted in death or failure of transplantation. It is concluded that the extravesical technique of Grégoir and Lich is the best method of avoiding urinary leakage, which is the most dangerous urologic complication of kidney transplantation.
