    Description / Table of Contents: Résumé La technique de la néphrotomie guidée par l'échographie pour localiser les calculs rénaux et par la sonographie-Doppler pour identifier les zones avasculaires du parenchyme rénal permet l'ablation transparenchymateuse des calculs sans avoir recours au clampage de l'artère rénale et au refroidissement rénal. Au cours de 175 opérations de ce type la perte moyenne de sang a été de 1,350 ml et le taux des échecs nécessitant une intervention secondaire a été de 2.8%. Malgré l'avènement de nouvelles modalités thérapeutiques non-invasives, cette méthode de traitement est encore employée dans 23% des cas de calculs coralliformes.
    Abstract: Resumen La técnica de nefrotomía guíada por ultrasonografía utilizando la escanografía de modo B para définir la localización de los cálculos y la sonografía de Doppler para identificar áreas avasculares del parenquima para la realización de las nefrotomías, permite la remoción tránsparenquimatosa de cálculos sin necesidad de oclusión de la arteria renal ni hipotermia del riñón. En 175 procedimientos realizados la pérdida promedio de sangre fue de 1,350 ml y la tasa de cálculos residuales que requirieron una intervención secundaria fue de 2.8%. A pesar del advenimiento de modalidades terapéuticas no invasivas, esta técnica todavía se aplica en 23% de los pacientes con cálculos coraliformes.
    Notes: Abstract The ultrasonically guided nephrotomy technique using B-scanning to identify the localization of stones and Doppler sonography to identify avascular parenchymal areas for nephrotomies allows for transparenchymal stone removal without the need for renal artery clamping and renal cooling. In 175 procedures the average blood loss was 1,350 ml and the rate of residual stones requiring a secondary intervention was 2.8%. Despite the advent of new noninvasive treatment modalities, this technique is still applied in 23% of staghorn stones.

    Description / Table of Contents: Zusammenfassung Für die Abklärung und Klassifizierung des vesiko-renalen Refluxes stehen eine Reihe diagnostischer Maßnahmen zur Verfügung, deren Aussagekraft nicht unumstritten ist. Aus diesen Gründen müssen therapeutische Entscheidungen bei der Refluxerkrankung häufig vom klinischen Verlauf abhängig gemacht werden. Durch die operative Refluxkorrektur kann mit hoher Zuverlässigkeit und geringer Komplikationsrate der vesiko-renale Reflux unabhängig vom präoperativ nachgewiesenen Refluxgrad beseitigt werden.
    Notes: Summary Detection and accurate grading of vesico-renal reflux is rendered difficult by the limited realiability of the different diagnostic procedures. Therapeutic decisions are therefore to a large extent influenced by the clinical situation. Properly performed antireflux surgery combines a high cure rate with a low complication rate.

    Extracorporeal shock wave lithotripsy (ESWL): alternatives and adjuvant procedures (1985)
    Springer
    World journal of urology 3 (1985), S. 48-52

    Notes: Summary Within a short time, extensive statistics on ESWL have documented its efficiency in the treatment of most renal and ureteral stones. Approximately 20% of all stone patients, however, require additional or other forms of therapy, such as URS, PNL, or surgery. Up to now, the differential indications for these procedures have not been completely established. A crucial factor for successful application of ESWL is stone volume and localization. Large stones with a central stone mass may be successfully treated by combining ESWL and PNL, while surgery is still preferred in those with a peripheral stone mass.

    Second generation shock wave lithotripsy: experience with the lithostar (1987)

    Notes: Summary Extracorporeal shock wave lithotripsy (ESWL) has been in clinical use for more than 5 years. Several devices commonly designated “second generation” lithotriptors are now under experimental or clinical trials. A multifunctional lithotriptor unit developed in cooperation with the Siemens Company in Germany is described, which utilizes an electromagnetic mode of shock wave generation along with local coupling to the patient. The results of 795 treatments are presented. The prototype has been in operation since March 1986. Adjuvant endourological measures, all of which have been performed on the same table, include insertion of double-J stents and ureteral catheters prior to ESWL in 27% of all treatments. Shock wave lithotripsy alone has been performed successfully under local anesthesia or a combination of parenteral analgesia and sedation. Results of treatment have been uniformly satisfying.

    Notes: Summary The telescope dilation set has been developed to allow for one-step percutaneous intrarenal instrumentation. As it is used for dilation as well as introduction of nephroscopes and nephrostomy tubes, it has become a central part of percutaneous procedures. A precise puncture technique has been developed to guarantee safe and effective use of the telescope dilators. Application in more than 300 cases involved minimal morbidity.

    The mainz-pouch (mixed augmentation ileum 'n zecum) for bladder augmentation and continent diversion (1985)

    Notes: Summary The ideal urinary reservoir constructed from bowel material should be a low-pressure system with a high capacity, capable of preventing upper tract deterioration resulting from ureteral obstruction or reflux. It should achieve reliable control of continence and assure easy emptying of the reservoir. In the Mainz-pouch, the combination of cecum and ileum, the latter of which is able to absorb pressure waves created by the cecum, produces a low-pressure system with a high capacity immediately postoperatively. By incorporating large bowel in our pouch, ureteral implantation can be done using a simple and reliable standard antireflux technique with a submucosal tunnel. The Mainz-pouch has been done since 1983 in 26 patients. Of these 11 were for bladder augmentation after subtotal cystectomy and 15 for continent urinary diversion. All of the patients with bladder augmentation are completely dry day and night; 2 patients with myelomeningocele are on intermittent catheterization for bladder evacuation. The remainder void spontaneously without significant residual urine. Of 15 patients with Mainz-pouch urinary diversion, 4 had an alloplastic stomal prosthesis implanted for control of continence and 11 have isoperistaltic ileo-ileal invagination, where by the invagination valve can easily be fixed to the intussuscepting ileum by sutures or staples. Of the 4 alloplastic stomal prostheses, 2 have been removed because of infection. In 1 of these patients, an ileo-ileal invagination was performed in the same operation to achieve continent closure. All patients with the invagination valve, as well as the 2 patients with an alloplastic stomal prosthesis, are completely continent, but in 3 cases, revision of the ileo-ileal invagination became necessary due to prolapse of the valve.

    Neurophysiology of penile erection (1989)
    Springer
    Urological research 17 (1989), S. 213-217

    Notes: Summary In 6 dogs and 6 monkeys electrical stimulation of the cavernous, pudendal and hypogastric nerve was performed to gain better understanding of the erectile neurophysiology. Arterial flow, intracorporeal pressure and venous restriction studies during single and combined neurostimulation demonstrated that initiation and maintenance of erection is a parasympathetic phenomenon. Penile rigidity however, could only be achieved with additional pudendal nerve stimulation resulting in muscular compression of the blood distended cavernous bodies. Detumescence or subsidence of erection is primarily under sympathetic control, due to inhibition of sinusoidal smooth muscle relaxation. On the basis of our observations we conclude that penile erection is dependent upon three neurophysiological mechanisms: 1. the parasympathetic “vascular mechanism”, the somatomotor “muscular mechanism” and the sympathetic “inhibitory mechanism”.
