    Notes: Abstract The authors report a new ultrasonic sign of urinary tract infection in children: thickening of the renal pelvis and/or ureteral wall. This thickening as encountered in 10 children, (10 months to 12 years) all with urinary tract infection, appears to result from inflammatory changes and to correspond to a sonographic sign of pyelitis and ureteritis. These alterations of the walls are similar to striations and folds described in this pathology on intravenous pyelograms. The thickening was the only sign of abnormality of the urinary tract in two cases; it was observed without reflux in four cases. The demonstration of this pattern should lead to further uroradiological investigations and to appropriate treatment.

    A hypothesis for the higher incidence of vesico-ureteral reflux and primary megaureters in male babies (1992)

    Notes: Abstract The authors propose a new explanation for the male preponderance in cases with prenatally diagnosed vesico-ureteral reflux and primary megaureters. The theory is based on conclusions drawn from the characteristics of 4 patients (3 perinatal cases and 1 occurring in a 14-year-old boy) presenting with unusual anomalies of the lower urinary tract. In this hypothesis, the male preponderance could be related to an abnormal dilatation of the posterior urethra occurring during the embryological development of the male urethra. The dilatation leads to a flap valve mechanism and to a functional obstruction of the bladder outlet and finally to secondary dilatation of the upper urinary tract. This obstruction may be transitory; reflux and megaureters found in utero or after birth could be considered as sequellae of this phenomenon.

    Notes: Summary A multicenter study was performed in 110 patients with superficial transitional cell carcinoma of the bladder. Adriamycin (50 mg/50 ml) was administered intravesically within 24 h after transurethral resection of TA-T1 (O-A) bladder tumors. Instillation was repeated twice during the first week, then weely during the first month and afterwards monthly for 1 year. The tolerance was evaluated in these 110 patients, and 29 patients presented with local side-effects. In 24 of these patients chemical cystitis was severe enough for them to drop out of the study. No systemic side-effects were observed. Recurrence was studied in 82 evaluable patients after 1 year of follow-up and in 72 patients followed for 2–3 years (mean 32 months). Of the 82 patients studied after 1 year, 23 had primary and 59 recurrent disease. Of the 82 evaluable patients, 50 did not show any recurrence after 1 year (61%), while 32 presented with one or more recurrence (39%). Of these recurrences, 27 were T1 tumors while five progressed to more highly invasive lesions. In patients that were free of recurrence during the first year, 80% remained tumor-free during the 2- to 3-year follow-up period. Of the patients developing one or more recurrences during the first year, only 50% presented with further recurrence once the instillations were stopped. The beneficial effect of Adrimacin appears obvious and might be related to the drug itself, the early and repeated instillations after TUR, or both.

    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.

    Embolization and subsequent nephrectomy in metastatic renal cell carcinoma (1984)

    Notes: Summary Twenty-five patients with primary metastatic adenocarcinoma renis were treated by embolization and delayed nephrectomy. The objective of the study was to examine whether the natural history of the disease is influenced by this combined treatment. Most patients (19/25) had measurable metastatic lesions. No patient received additional therapy unless progression occurred. Embolization was mainly performed with Gelfoam and Gianturco coils. Complete remission of metastases was observed in 1 patient (still in remission after 36 months); stable disease in 6 patients (lasting between 14 and 31 months). Eighteen patients died after a median survival of 5.7 months (range 14 days to 11 months). No major complication related to the embolization procedure occurred. Angio-infarction followed by nephrectomy cannot be recommended for widespread use in patients with primary metastatic kidney carcinoma. The procedure may be tested in controlled clinical trials together with other treatment protocols, such as immunotherapy, infarction with radioactive particles, or chemoembolization. These approaches are experimental and therefore limited to institutions with sufficient experience.

    Renal pseudotumors (1984)

    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.

    Sonographic evaluation of renal inflammatory diseases in children (1988)

    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.

    Transurethral hyperthermia for benign prostatic hypertrophy (1991)
    Springer

    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.

    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.
