    Notizen: Summary In January 1986, a cooperative study was started at the Katharinenhospital in Stuttgart, FRG (modified Dornier HM-3) and Kreiskrankenhaus in Kempten, FRG (Wolf Piezolith 2200) to evaluate the range of indications, efficacy and required anesthesia of both lithotriptors. Stone classification and general indications for interventional therapy were similar in both centers. The Dornier HM-3 operates with a modified generator and a new ellipsoid which provide low pressure lithotripsy. With the Piezolith 2200, 99% of ESWL-treatments were performed without any anesthesia, whereas with the modified Dornier HM-3 lithotriptor, minor analgesia using tramadol was necessary in 92%, epidural anesthesia in 8%. The overall success rate was similar in both centers (Piezolith 2200: 94.5% vs Dornier HM-3: 98%). Only 46% of the patients were treated successfully in one session with the Wolf lithotriptor compared to 88% with the Dornier HM-3. Ultrasound localization with the Piezolith 2200 failed in 58% of ureteral calculi, whereas fluoroscopic stone localization (Dornier HM-3) was insufficient in the majority of slightly or nonopaque calculi.

    Notizen: Summary We report the efficacy and toxicity of combined methotrexate, vinblastine, 4′-epirubicin and cisplatin (M-VEC) for the treatment of advanced urothelial tract tumors in 58 evaluable patients. Histologically, the patients had pure transitional-cell carcinoma (89.7%), squamous-cell carcinoma (8.6%) and anaplastic carcinoma (1.7%). Locally advanced disease (pT3-4 N0 M0) was present in 22 patients (37.9%); pelvic lymphnode metastases (pT3-4 N1-3 M0), in 20 (34.5%); and metastatic disease, in 16 (27.6%). Response was observed in 72.3% of the patients, with complete remission achieved by 51.7%. Response rates and survival were influenced by histological subtype and tumor stage. Squamous-cell carcinoma did not respond to M-VEC chemotherapy. There was one drug-related death (1.7%); otherwise, toxicity was mild to moderate. Adverse effects included cardiac toxicity (9%), mucositis (5.1%), nadir sepsis (1.7%) and renal failure (1.7%) in a small number of patients.

    Notizen: Summary A system was developed and built for recording and processing urodynamic measurements during a 24 h period. The essential requirement was to obtain these signals without psychological stress. The system was small enough to allow the patient to move freely. Semiconductor pressure transducers were employed for measuring total bladder and rectal pressures and detrusor pŕessure was obtained by subtraction. Results gained with this method revealed some differences to those obtained with conventional methods.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Transportable Lithotripsiegeräte werden in zunehmendem Maße in urologischen Kliniken zur Harnsteinbehandlung eingesetzt, wenn kein festinstallierter Lithotriptor vorhanden ist bzw. eine solche Anschaffung als unrentabel angesehen wird. In der vorliegenden Studie wird überprüft, inwieweit die Komplikationsrate bei diskontinuierlicher Anwendung der ESWL mit transportablen Lithotripsiesystemen von den bekannten Komplikationsdichten aus etablierten Zentren verschieden ist. An bis zu 54 Kliniken wurde die Komplikationsrate bei diskontinuierlicher Anwendung transportabler Lithotripsiesysteme von 1993–1995 bei insgesamt 12 901 Therapien erfaßt. Schwerwiegende Komplikationen ergaben sich in insgesamt 85 Fällen (0,66 %). Die Mehrzahl davon (n = 64) waren intra- oder perirenale Hämatome; 3mal mußte nephrektomiert werden. Die Mortalität lag bei 0 %. Für die einzelnen Komplikationen lassen sich aus diesen Fallzahlen Wahrscheinlichkeiten ihres Auftretens berechnen. Insgesamt zeigt die Untersuchung, daß die ESWL mit mobilen Systemen mit der gleichen geringen Komplikationsrate angewendet werden kann, wie sie von etablierten Steinzentren bekannt ist.
    Notizen: Summary An increasing number of urological departments are taking advantage of portable lithotripsy units if a system is not available in their clinic or purchase does not seem feasible; however, infrequent application of ESWL in such a setting should not increase the rate of complications. From 1993 to 1995, up to 54 urological departments using mobile lithotripsy units collected data concerning all major complications. A total of 12 901 treatments were performed which led to 85 major complications (0.66 %). Of them 64 were intrarenal or perirenal hematomas. There was no fatal complication. In three patients nephrectomy had to be performed subsequently. The probability of complications can be calculated according to these data. Overall, less frequent application of ESWL does not yield higher complication rates than those at ESWL centers where larger numbers of treatments are performed.
